Should I choose the 1.4 or 1.5 for Lavida?

The difference in power between the 1.5L and 1.6L engines of the Lavida is minimal. The 1.5L engine is a newer design by Volkswagen, with slightly better technology compared to the 1.6L, but there is almost no difference in power. You can make your choice based on your actual needs. Below is a detailed comparison of the two: 1. Power: The 1.4T is lower than the 1.5T. 2. Fuel consumption: The difference between the two is not significant. However, it's important to note that the 1.5 requires 92-octane gasoline, while the 1.4T model requires 95-octane or higher. In the long run, the 1.5 naturally aspirated model has lower usage costs. 3. Maintenance: Maintenance costs are definitely higher for the 1.4T model compared to the 1.5. In terms of oil grade and quality, the 1.4T model, being turbocharged, requires higher-quality oil, typically full synthetic oil.

What are the reasons why the Land Cruiser's one-touch start fails to ignite?

Land Cruiser's one-touch start fails to ignite for the following reasons: 1. Smart key battery dead: When the vehicle's smart key is out of battery, the key's transmission power is very low, making it difficult for the in-car sensor to detect it. 2. Gear not in P position: If the vehicle is in D or R gear and can be directly started, the sudden movement of the vehicle at ignition poses a significant safety hazard. 3. Steering wheel locked: The steering wheel lock is a simple anti-theft feature. When the car is turned off, turning the steering wheel from the straight position to a certain angle in one direction will lock the steering wheel with a click. In the locked state, the one-touch start function will not work.
