For automatic transmission cars on highways, you can use the S gear or D gear. The following are the speed regulations for highway driving: 1. Vehicle speed limits: The maximum speed for small passenger cars must not exceed 120km/h, other motor vehicles must not exceed 100km/h, motorcycles must not exceed 80km/h, and the minimum speed must not be lower than 60km/h. 2. Lane speed limits: For roads with 2 lanes in the same direction, the minimum speed for the left lane is 100km/h; for roads with 3 or more lanes in the same direction, the minimum speed for the leftmost lane is 110km/h. The minimum speed for the middle lane is 90km/h, and vehicles traveling at speeds above 60km/h but below 90km/h should drive in the rightmost lane.

Can the Rear Seats of a Station Wagon Lie Flat?

It is not recommended to lie flat while the car is in motion, as it is very dangerous. In the event of a collision, a person could be thrown out, which would likely be fatal. It is best to wear a seatbelt while driving. Station Wagon Models: Station wagons are considered a niche model in China, similar to pickup trucks. Although they are not as restricted as pickups, they still haven't gained much popularity over the years. In countries like Europe and the US, station wagons are practically a must-have family vehicle. Station Wagon Cargo Space: The rear seats can be completely folded down, and the enormous trunk space can be fitted with a mattress. Without exaggeration, this space can accommodate two adults lying flat. If all the seats are folded down, it essentially leaves only the driver and front passenger seats.

Where is the horn located on a Jetta?

The horn of a Jetta is positioned behind the front bumper, typically featuring both high and low tones or sometimes just a high tone. The horn serves as the vehicle's audio signaling device, allowing the driver to emit sound signals as needed or required during driving to warn pedestrians and other vehicles, ensuring traffic safety. It is also used to prompt action or convey signals. A single honk is a greeting to oncoming vehicles, especially when used during a turn to alert vehicles on the other side to drive cautiously. Two honks are a signal for the vehicle ahead to be aware of the following vehicle's actions, as relying solely on turn signals might be overlooked if the leading driver isn't checking mirrors. Three honks are typically used on inclines or declines to remind descending vehicles to yield to ascending ones. The Jetta measures 4501mm in length, 1704mm in width, and 1469mm in height, with a wheelbase of 2604mm, and features front-wheel drive.

How to Step on the Accelerator?

Methods of stepping on the accelerator: 1. Each car has different performance, and the sensitivity of the accelerator varies. Test the accelerator first when stepping on it; 2. After getting the car, lightly step on the accelerator, gradually shift gears, and observe the speed. If the acceleration is slow and the speed doesn't increase, the accelerator is relatively stiff, so you need to gradually increase the force applied; 3. Normally, avoid stepping on the accelerator all the way down. Even in good road conditions, start by lightly stepping on the accelerator before smoothly increasing the pressure; 4. Avoid uneven force when stepping on the accelerator—don't alternate between light and heavy pressure. Keep the foot pressure steady; 5. Do not step on the accelerator when going downhill. Keep your foot on the brake, ready to brake at any time.

What to Do When the Battery Is Dead and the Car Won't Start?

When the battery is dead and the car won't start, you can use the push-start method or the jump-start method. If the car battery dies on the road and the car won't start, the first method is to push the car to help it start. At this time, the road condition is very important. If it happens to be a downhill slope, pushing the car will become much easier and the car will start more smoothly. First, press the clutch, shift into gear, and when reaching a certain speed, ignite while giving gas. Once the engine starts, quickly press the clutch pedal while controlling the throttle to prevent the engine from stalling, then slowly stop the car. The jump-start method involves finding a vehicle that can start normally, positioning the two cars front to front, opening the hood, and using jumper cables—positive to positive, negative to negative. Then, the stalled vehicle can start normally by igniting.

What are the effects of sun exposure and rain on a car?

It has a significant impact. Prolonged parking under wind and sun exposure can lead to aging of the wiring and loss of gloss on the paint surface. Rainwater contains acidic substances that can erode the car's surface paint. It is recommended to park the car in a garage. Damage from rain: The main issue with rain is damage to the paint. If parked in a less-than-ideal environment, acid rain can easily occur, which also harms the paint. Additionally, rain can cause corrosion of certain car components, leading to short circuits and potential hazards. Wash the car as soon as possible: After heavy rain, wash the car as soon as possible. If parking for an extended period, it's best to park in a garage. If a garage is not available, it's advisable to use a car cover to shield the car from tiny airborne particles and corrosive substances that can damage the paint.
