Q
how to reset tyre pressure mercedes
To reset the TPMS on your Mercedes, first make sure all tires are inflated to the vehicle's recommended pressure – you'll usually find that info on the door jamb sticker or in the owner's manual. Fire up the car, then navigate to the instrument cluster menu. Look for options like "Service" or "Tyre Pressure," then select "Confirm New Pressures" or a similar function to finish the reset. If your Merc has steering wheel buttons, use the left/right arrows and the "OK" button to get it done.
Heads up though – newer models like the W205 or W213 might require you to do this while stationary, using the "Vehicle Settings" on the central display. Older models, on the other hand, might need a dedicated diagnostic tool. With Malaysia's hot weather, tire pressure can creep up as temperatures rise, so it's smart to check pressures monthly when the tires are cold. That avoids issues like increased fuel consumption or uneven tire wear.
Also, remember Mercedes' indirect TPMS relies on wheel speed sensors to detect changes in tire circumference. So if you swap out tires or wheels, you *must* reset the system to keep it accurate. If that TPMS warning light stays on, it could be a puncture or a faulty sensor – best to swing by an authorized service center to get it checked out ASAP.

Q
What is the lifespan of an EV battery?
The lifespan of electric vehicle batteries typically ranges from 5 to 8 years, depending on the battery type, usage habits, and maintenance conditions. Taking mainstream ternary lithium batteries as an example, their cycle count is approximately 1500 to 2000 times. Assuming each cycle allows a driving distance of 500 kilometers, and with an annual driving distance of 20,000 kilometers, the theoretical lifespan can reach 300,000 to 500,000 kilometers or 6 to 8 years. However, the actual lifespan is affected by various factors. For instance, adverse conditions such as high or low temperature environments, frequent sudden acceleration or braking, and overcharging/discharging will shorten the battery lifespan. In contrast, regular maintenance, avoiding extreme charging/discharging (e.g., charging when the remaining battery level is 20%), and using appropriate charging equipment can extend the service life. Lead-acid batteries have a shorter lifespan of about 1.5 to 2 years, while lithium iron phosphate batteries have a theoretical lifespan of up to 7 to 8 years. Some manufacturers offer long-term warranty services, and it is recommended that car owners regularly check the battery status. If difficulties in starting the vehicle or a significant decrease in driving range occur, battery replacement should be considered. The cost of battery replacement varies greatly depending on capacity and type, usually ranging from a few thousand to tens of thousands of ringgit.
Q
Is a Tesla an EV?
Tesla is a pure electric vehicle brand, and all its models are equipped with electric drive systems without involving fuel engine technology. As the world's first electric vehicle manufacturer to apply lithium-ion battery technology on a large scale, Tesla has delivered multiple models including Model 3, Model Y, and Model S to over 30 countries since 2008. Among them, the Model 3, as a mid-size electric sedan, features a 202kW motor with 404N·m torque and utilizes lithium iron phosphate batteries, while the Model Y, positioned as a mid-size electric SUV, provides superior cargo space. Its core technological strengths lie in the three-electric system (battery energy density of 85kWh, range of 440km), intelligent driving (standard 8-camera Autopilot system), and suspension design (double-wishbone + multi-link independent suspension), complemented by a dedicated charging network to address energy replenishment needs. In the local market, Tesla models are priced from 235,500 MYR for the Model 3 to 939,900 MYR for the Model X, aligning with the premium positioning of new energy vehicles. The continuous optimization of vehicle performance through OTA upgrades further significantly enhances the user experience.
Q
What is the EV sales in May 2025?
As of May 2025, specific monthly sales data for Malaysia's electric vehicle (EV) market has not yet been publicly disclosed, but the overall trend can be inferred from comprehensive industry reports and registration statistics. In the first four months of 2025, BYD led the market with cumulative registrations of 3,207 units, followed by Proton eMas 7 at 2,537 units, while Tesla ranked third with 735 units. Extrapolating from the first three quarters' data, BYD's annual sales are projected to surpass 8,417 units, with Proton reaching 6,212 units, reflecting dual-track growth in both pure electric models (e.g., BYD Sealion 7 and Atto 3) and localized offerings (e.g., Proton eMas 7). Market expansion is fueled by policy incentives (including import duty exemptions) and product diversification, though charging infrastructure (currently around 2,000 public chargers) and local production capacity remain critical bottlenecks. The government targets a 20% EV adoption rate by 2030, against the current 7% penetration, highlighting coexisting growth potential and challenges.
Q
Does 7th gear exist?
The 7-speed gearbox does exist; it is an automatic transmission with 7 forward gears, commonly found in models using dual-clutch technology. The gear settings of such gearboxes include Park (P), Reverse (R), Neutral (N), and Drive (D). Some models also offer specific gears like D1, D2 and a Sport mode (S) to meet different driving needs. The 7-speed dual-clutch gearbox operates through the alternating engagement of two clutches: one responsible for odd-numbered gears (1st, 3rd, 5th, 7th), and the other managing even-numbered gears (2nd, 4th, 6th), enabling rapid and seamless gear shifts while balancing fuel efficiency and power responsiveness. Based on clutch type, it can be categorized into dry and wet variants. The dry-type features a simpler structure and higher transmission efficiency but inferior heat dissipation, making it suitable for small-displacement engines; the wet-type employs oil cooling to handle greater torque, albeit at higher cost. Such transmissions have been extensively adopted in numerous mainstream models in domestic markets, demonstrating high technical maturity, with future development trends focusing on intelligentization and weight reduction. Notably, the 7th gear in these transmissions typically serves as an overdrive ratio designed for highway cruising, effectively lowering engine RPM and enhancing fuel economy.
Q
Is a V14 engine possible?
The V14 engine does exist, but it is a relatively rare configuration, mainly used in large medium-speed diesel engines for power generation and marine propulsion. This type of engine adopts a V-shaped arrangement with two banks of 7 cylinders each, which can provide higher power output and lower emissions. For example, the MAN B&W V14 engine has a power range of 7,000 to 16,800 kilowatts and has been used in some cruise ships such as "Explorer Dream" and "Norwegian Spirit". However, the V14 design is hardly used in the passenger car market due to its large size and high cost, making it more suitable for industrial or marine applications with fewer space constraints. Currently, the mainstream passenger car engines are still four-cylinder, six-cylinder or eight-cylinder, balancing performance and fuel economy. There are also products with similar names in the hydromechanical field, such as the Parker V14 series of bent-axis piston motors, but they are hydraulic system components and have nothing to do with internal combustion engines.
Q
Why do cars have seatbelt alarms?
Cars come with seatbelt reminder alerts mainly to boost driving safety, using audio or visual cues to get passengers to buckle up and cut down on injury risks in accidents. Studies show that proper seatbelt use can slash the chance of fatal injuries by around 50%, which is why so many countries make this feature a mandatory standard. Modern vehicle alert systems usually go with a progressive reminder—starting with a gentle chime, then ramping up if ignored. Some models even show exactly which seatbelt isn’t fastened on the dashboard. Beyond legal requirements, these designs also highlight automakers’ focus on safety tech. Take high-end models, for example—some link up with pre-tensioning seatbelts or airbag systems to automatically tighten before a crash. It’s worth noting, though, while alerts do a solid job of increasing seatbelt use, drivers forming the habit of buckling up on their own is way more crucial. After all, no matter how advanced the reminder, it can’t replace personal safety awareness.
Q
What happens if a passenger doesn't wear a seatbelt?
If passengers don't wear seatbelts, they first face legal risks. According to traffic laws, all passengers in a vehicle must wear seatbelts; otherwise, they could be fined. More importantly, not wearing a seatbelt drastically increases the risk of injury in an accident. When a vehicle suddenly decelerates or crashes, passengers might be thrown from their seats, hit hard objects inside the car, or even ejected from the vehicle entirely, leading to severe injuries or death. Seatbelts are designed to hold passengers in place during a crash, distribute the force of impact, and reduce harm to the head, chest, and spine. Additionally, not wearing a seatbelt can compromise the effectiveness of airbags. Airbags work in conjunction with seatbelts, and using an airbag alone could even cause secondary injuries. It's worth noting that accidents can happen suddenly, even at low speeds or during short trips. So whether the journey is long or short, fast or slow, wearing a seatbelt is a must. Some passengers might think the back seat is safer and skip the seatbelt, but in reality, rear passengers face just as much risk—especially in rear-end collisions or rollovers. For your own safety, both drivers and passengers should make it a habit to buckle up as soon as they get in the car.
Q
What is the function of ESC in a car?
ESC (Electronic Stability Control) is a crucial car safety tech that's all about keeping you in control when things get tricky—like during sudden swerves or on slippery roads. Here's how it works: sensors constantly track how the vehicle's moving. If it detects wheels slipping or the car veering off your intended path, the system jumps into action. It automatically applies the brakes to individual wheels and tweaks the engine's power output to help you regain control, cutting down on the risk of skidding or rolling over. This stuff really shines on rainy days or when taking sharp turns, making driving way safer. And ESC isn't alone—modern cars also come with other helpers like ABS (Anti-lock Braking System) and TCS (Traction Control System). These systems team up to boost stability and handling. When you're car shopping, it's a smart move to prioritize models with these safety features. Trust me, they make for a much more secure driving experience.
Q
Is ESC in every car?
Electronic Stability Control (ESC) isn't standard on all vehicles, but its adoption in new cars has increased significantly in recent years. Particularly, since 2014, regions like the EU and the US have mandated ESC for new vehicles, so most imported cars or global models come equipped with it. In the local market, mid-to-high-end models and new cars from major brands generally have ESC, but some entry-level models or older used cars might still lack this feature. When buying a car, you can check the "ESC OFF" indicator on the dashboard or the vehicle specification sheet to confirm. ESC uses sensors to detect wheel slip and automatically adjusts braking force or engine output, effectively preventing loss of control due to understeer or oversteer, which is especially noticeable on rainy, slippery roads. If your budget allows, it's recommended to prioritize models with ESC. Also, keep in mind that this system can't overcome physical limits, so safe driving habits remain fundamental. Other common active safety features like ABS (Anti-lock Braking System) and TCS (Traction Control System) usually work in conjunction with ESC, and together the three enhance driving stability.
Q
Which cars have Electronic Stability Control?
Most new cars from major brands these days come with Electronic Stability Control (ESC), a key part of modern automotive safety tech. You'll find it on Japanese models like Toyota, Honda, Nissan, Mazda, and Mitsubishi, European rides such as Volkswagen, BMW, and Mercedes-Benz, Korean cars from Hyundai and Kia, and even locally assembled domestic vehicles like the Proton X70 and X50, where it's standard. ESC uses sensors to monitor the car's movement. If it detects a skid or loss of control, it automatically adjusts engine power and braking to help the driver keep the vehicle stable—super useful on wet roads or tight turns. As safety regulations get stricter and consumers become more aware, ESC has moved from a high-end option to a common feature even on budget cars. When buying, just check the spec sheet or ask a sales rep. Some brands might call it VSC, DSC, or other names, but the basic function is the same. I’d recommend prioritizing cars with ESC. After all, you can never have too many safety features, and this tech has been proven over the years to cut down accident risks.

Q
What are EV cars called?
Electric vehicles are commonly referred to as EVs (Electric Vehicles) or pure electric vehicles locally. Among them, the e.MAS series launched by Proton and Perodua's QV-E are currently representative local electric vehicle models. The Proton e.MAS brand covers models such as mid-size SUVs, including the e.MAS 7 and the entry-level e.MAS 5, with the latter priced at RM 59,800 and targeting the economy segment. As Perodua's first independently developed pure electric hatchback, the QV-E adopts a battery-swapping model, featuring a body price of RM 80,000, a 52.5 kWh battery, and a range of 445 km. Additionally, local startups have developed the MyKar 1.0 concept car based on the Honda Jazz and showcased an unofficial Axia Electric prototype. The government aims for new energy vehicles to account for 20% of new car sales by 2030. Currently, electric vehicle sales are growing significantly, with a 112% year-on-year increase in the first half of the year. These developments demonstrate that local automakers are accelerating their electrification transformation through technical collaboration and independent innovation, offering consumers more diversified choices.
Q
What is the future of EV?
The development prospect of electric vehicles in Malaysia is very promising, and significant growth is expected in the next few years. According to market research data, the sales volume of pure electric vehicles will surge by 102.6% year-on-year to 20,167 units in 2025, while the sales of hybrid vehicles will also increase by 20.5%, indicating that new energy vehicles have become the core growth driver of the market.
The government plans to raise the sales share of new energy vehicles to 20% by 2030 and build 10,000 public charging piles. Currently, there are over 2,000 charging infrastructure facilities, mainly concentrated in major urban areas.
Local assembly (CKD) has become a strategic focus for automakers. Benefiting from the government's tax incentives extended until 2027, brands such as BYD and Xpeng are accelerating their local production layout. Local manufacturers like Proton and Perodua are also actively launching electric models; for example, the Proton e.MAS 5, priced affordably between RM 65,800 and RM 69,800, has received a large number of orders.
Although the expiration of tax incentives for fully imported vehicles may cause short-term market fluctuations, policy support, improved industrial chain maturity, and increased consumer acceptance will continue to drive the electrification transformation. In the medium to long term, with the improvement of charging networks, the enrichment of vehicle model options, and the reduction of costs, electric vehicles are expected to gradually become the mainstream travel choice, helping to achieve the national target of 38% penetration rate by 2030.
Q
Is it better to buy EV or hybrid car?
When choosing between an electric vehicle (EV) or a hybrid vehicle in Malaysia, one needs to comprehensively consider usage scenarios, infrastructure, and policy support. Currently, hybrid vehicles are more popular, with sales reaching 30,796 units in 2024, accounting for 67% of total new energy vehicle sales. Their advantages lie in not relying on charging stations—they can operate purely on electricity in urban areas to achieve low emissions, while relying on fuel engines for long distances to avoid range anxiety, making them suitable for regions where charging infrastructure is still under development. Although EV sales are growing rapidly (a 45% year-on-year increase to 14,766 units in 2024), they depend on the charging network. The government is accelerating the deployment of home, public, and fast-charging stations, and extending tax incentives until 2027, which will improve convenience in the future. If daily travel primarily involves short urban commutes and a home charging station can be installed, EVs are more economical and environmentally friendly; if frequent long-distance travel is required or charging access is limited, hybrids remain a practical choice. Both options qualify for tax incentives, but hybrid technology is more mature and maintenance costs are lower, making it the dominant transitional solution at present.
Q
How much does it cost to replace an EV battery?
The battery replacement cost for new energy vehicles varies significantly depending on the vehicle model, battery type, and capacity. For micro electric vehicles like the Wuling Hongguang MINIEV with a 120km range, battery replacement costs approximately 5,000-12,000 Malaysian Ringgit, while the 300km version costs about 18,000-25,000 Malaysian Ringgit. For mainstream family cars, the LFP battery pack for the BYD Dolphin costs around 46,000-50,000 Malaysian Ringgit. The rear-wheel-drive Tesla Model 3 costs about 126,900 Malaysian Ringgit, and the all-wheel-drive version with a ternary lithium battery costs approximately 172,000 Malaysian Ringgit. For hybrid models such as the BYD Qin PLUS DM-i, a full battery pack replacement ranges from 10,000 to 30,000 Malaysian Ringgit. Among battery types, ternary lithium batteries are 20%-30% more expensive than LFP batteries. For high-end brands like the Tesla Model S, battery replacement may cost 140,000-300,000 Malaysian Ringgit. Owners should note warranty policies—for instance, BYD's first owners receive a lifetime warranty on battery cells. To prolong battery life, avoid maintaining a charge level below 20% for extended periods. When purchasing a vehicle, prioritize models with modular maintenance support or lifetime warranties to minimize long-term costs.
Q
Is EV cars AC or DC?
The battery system of an electric vehicle (EV) uses direct current (DC) to store energy, but the charging process involves the conversion between alternating current (AC) and direct current. During charging, the alternating current (AC) supplied by household power sources or public charging piles needs to be converted into direct current (DC) through an on-board or external charger to charge the battery. Therefore, the AC port marked on the charger is the input, and the DC port is the output. Fast charging stations usually provide high-voltage direct current (DC) directly, bypassing the on-board conversion process to shorten charging time. Understanding this principle helps in choosing a suitable charging method, for example, household AC charging is suitable for slow charging at night, while DC fast charging is more suitable for quickly replenishing energy during long-distance trips.
