How to pair the Bluetooth of Volkswagen Passat with your phone?

All models of the 2019 Alfa Romeo Stelvio are equipped with a timing chain design instead of a timing belt. This configuration is commonly found in its 2.0-liter turbocharged four-cylinder gasoline engine and 2.2-liter turbocharged diesel engine (the Malaysian market mainly uses gasoline engines). Compared with the timing belt, the timing chain has a longer service life. Generally, it can last for the entire life of the engine and doesn't require regular replacement. You only need to regularly check the status of the lubrication system, which can significantly reduce the long-term maintenance costs for Malaysian car owners in the tropical climate. However, the chain makes a bit more noise during operation, and lack of proper oil maintenance may cause wear on the guide plate. It is recommended that Stelvio owners follow the original factory's maintenance schedule to replace high - quality engine oil. It's worth noting that although the timing chain is highly durable, if there are abnormal noises or tooth - skipping symptoms, it still needs to be repaired in time. This is in contrast to the problem of the timing belt, which is prone to aging in Malaysia's rainy and humid environment. Usually, the timing belt needs to be replaced every 60,000-100,000 kilometers. For local users who pursue low-maintenance convenience, the chain design of the Stelvio is a more worry-free choice. At the same time, the high-speed characteristics of Alfa Romeo engines are also more suitable for the precise transmission requirements of the chain.

The 2019 Alfa Romeo Stelvio offers a variety of configuration options in the Malaysian market. It is equipped with a 2.0-liter turbocharged gasoline engine, with a maximum output power of 280 horsepower and a peak torque of 400 N·m. It is paired with an 8-speed automatic transmission, and it only takes 5.7 seconds to accelerate from 0 to 100 km/h, showing outstanding performance. It comes standard with a full-time all-wheel-drive system (Q4), an adaptive suspension, and a DNA driving mode selection system (Dynamic, Natural, and Advanced Efficiency), which combines both sportiness and comfort. The interior features leather seats, an 8.8-inch central control screen (supporting Apple CarPlay/Android Auto), and aluminum shift paddles. Safety features include forward collision warning, automatic emergency braking, and lane-keeping assist. It's worth noting that the Stelvio shares a rear-wheel-drive architecture with the Giulia on the same platform. This design is quite rare in SUVs, giving it a handling experience closer to that of a sedan. For Malaysian consumers, its status as an imported vehicle and its unique Italian design language make it stand out in the luxury mid-size SUV market. However, it should be noted that maintenance and repairs need to be carried out through officially authorized channels. The vehicle has a fuel tank capacity of 64 liters, and the combined fuel consumption is approximately 7-8 liters per 100 kilometers, making it suitable for users who seek driving pleasure and also need practical space.

The top speed of the 2019 Alfa Romeo Stelvio varies depending on the vehicle configuration. The regular version equipped with a 2.0-liter turbocharged engine can reach a top speed of up to 230 km/h. Meanwhile, the more powerful Quadrifoglio version comes with a 2.9-liter V6 twin-turbocharged engine, and its top speed can be increased to 283 km/h, demonstrating the Italian brand's profound expertise in sporty tuning. For Malaysian car enthusiasts, the Stelvio not only offers outstanding top-speed performance. Its iconic Alfa Romeo DNA driving mode system can also adapt to the diverse local road conditions. Through the three modes of Dynamic, Natural, and Advanced Efficiency, the vehicle's characteristics can be flexibly adjusted, balancing the comfort of daily driving and the excitement of track-like performance. It's worth mentioning that when such high-performance SUVs are driven in Malaysia's hot climate for a long time, it is recommended to regularly check the cooling system and tire condition to ensure that the vehicle always maintains its best performance, while enjoying the unique driving pleasure and Italian design aesthetics of Alfa Romeo.

For the 2019 Alfa Romeo Stelvio, it is recommended to conduct regular maintenance every 10,000 kilometers or 12 months, whichever comes first. The main items include changing the engine oil and oil filter, and checking the brake system, tires, suspension, and the status of various fluids. In Malaysia's hot and humid climate, it is advisable to pay extra attention to the cabin air filter and the battery health. When the mileage reaches 20,000 kilometers, the air filter needs to be replaced. At 40,000 kilometers, a major maintenance such as changing the transmission fluid and differential fluid is required. As an imported Italian model, the Stelvio is equipped with precision components like an all-aluminum engine. It is recommended to strictly follow the original manufacturer's maintenance specifications and use certified 0W-20 fully synthetic engine oil. Malaysian car owners should also pay attention to regularly cleaning the vehicle's underbody to prevent seawater corrosion. If you often drive in congested areas, you can appropriately shorten the replacement cycle of the brake fluid. The Q4 all - wheel - drive system and the DNA driving mode selector installed in this car need to be calibrated with professional equipment. It is recommended to choose an Alfa Romeo authorized service center for maintenance. They are familiar with the maintenance points of the unique MultiAir solenoid valve technology of this model, which can ensure that the vehicle maintains its best performance.

The 2021 Lexus ES 250 doesn't use a turbocharged engine. Instead, it's equipped with a 2.5 - liter naturally aspirated four - cylinder engine with a maximum output of 203 horsepower, paired with an 8 - speed automatic transmission. This powertrain is well - known for its smoothness and reliability, making it highly suitable for city driving and long - distance trips in Malaysia. The Lexus ES series has always been promoted for its luxury, comfort, and noise - reduction technology. The 2021 ES 250 also has many upgrades in interior materials and technological features. For example, the Lexus Safety System+ comes as standard, which includes functions like pre - collision warning and lane - keeping assist, enhancing driving safety. For Malaysian consumers, although naturally aspirated engines don't have the same explosive power as turbocharged models, their maintenance costs are relatively low. Moreover, the Lexus brand has a well - established after - sales service network locally, making long - term use more worry - free. If you have higher power requirements, you can look into the ES 300h hybrid version, which strikes a better balance between fuel economy and performance.
