What are the precautions during the break-in period of the Tiguan L?

Tiguan L's break-in period requires attention to three main aspects: preheating before starting, avoiding emergency braking, and preventing excessive load. Below are detailed explanations: Preheating before starting: For fuel-injected vehicles, before starting, turn the key to the second position and wait for 5-10 seconds before ignition. This is because once the ignition is turned on, the fuel pump begins operating to adjust oil pressure and injection volume. Waiting a few seconds before starting helps protect the new engine. Avoiding emergency braking: Emergency braking not only shocks the braking system during the break-in period but also increases impact loads on the chassis and engine. It is advisable to avoid emergency braking within the first 300 kilometers of driving. Preventing excessive load: If a new car operates at full capacity during the break-in period, it can cause damage to mechanical components. Therefore, within the first 1,000 kilometers, domestic vehicles should not exceed 75%-80% of their rated load capacity.

Where is the accelerator pedal located in a car?

In an automatic transmission car, the accelerator pedal is on the right side, while the brake pedal is on the left. There are only two pedals in an automatic car, and both must be controlled exclusively by the right foot. Never use one foot for each pedal. For manual transmission cars, there are three pedals arranged from left to right: the clutch pedal, brake pedal, and accelerator pedal. The left foot controls the clutch pedal, while the right foot manages both the brake and accelerator pedals. A common mistake of confusing the accelerator for the brake often occurs during reversing, as drivers tend to turn their heads to look backward, focusing their attention entirely on the rear, which may cause their right foot to confuse left and right. When not pressing the accelerator, always keep your foot on the brake pedal, regardless of whether you're reversing or not. This way, when reversing, your right foot is already on the brake pedal, and to move the car backward, you must lift your foot from the brake to press the accelerator, thus avoiding the mistake of pressing the accelerator instead of the brake.

Does an eight-year-old car need an annual inspection?

An eight-year-old car does require an annual inspection. Here are the relevant details about vehicle inspections: 1. Timeframe: For passenger cars and blue-license-plate minivans, new vehicles must undergo inspection every two years for the first six years after registration; after six years, they require annual inspections; after ten years, inspections are conducted once a year, and after fifteen years, twice a year. For trucks, inspections are required annually after registration, and after ten years, twice a year. 2. Regulations: If a vehicle is found by traffic police to have not undergone inspection, the owner may face fines or have the vehicle impounded. Additionally, in insurance contracts, vehicles that have not been inspected on time are considered unqualified, and no claims will be paid in the event of an accident.

Where is the cabin air filter located in the Wuling Zhiguang?

The cabin air filter in the Wuling Zhiguang is located inside the glove box. First, remove the black plastic panel above the passenger footwell, then disconnect the negative battery terminal. Next, remove the body control module and its mounting bracket (secured by two 12mm nuts). After that, take off the panel on the left side of the passenger footrest to access the cabin air filter. The Wuling Zhiguang is a microvan with body dimensions of 3797mm (length) × 1510mm (width) × 1820mm (height) and a wheelbase of 2500mm. Power comes from a 1.2L 76hp L4 naturally aspirated engine paired with a 5-speed manual transmission, delivering a maximum power output of 56kW.

What is the difference between semi-slick and full-slick tires?

semi-slick and full-slick tires are different in the following aspects: 1. In terms of nature: Full-slick tires melt into a gel-like state when they rub against the road surface and the tread temperature rises during use, providing excellent grip for the vehicle. Semi-slick tires can achieve grip close to that of full-slick tires when the temperature rises, and the wear level is also within a controlled range. 2. In terms of grip: When semi-slick tires reach their operating temperature, they soften the tire tread, creating high stickiness, thereby improving grip. 3. Different characteristics: Full-slick tires increase the contact area with the road surface, enhancing grip when a certain temperature is reached. Semi-slick tires do not have this feature.

Why is there a gear friction sound when stepping on the accelerator?

Stepping on the accelerator produces a gear friction sound due to inaccurate signals from the engine knock sensor. Here are some related introductions about the car accelerator: 1. Function of the car accelerator: The throttle in a gasoline engine does not control the fuel injection volume but rather the opening size of the throttle valve. A smaller opening means less mixture enters the cylinder, resulting in lower engine power output, and vice versa. 2. Solutions for a heavy accelerator pedal: If the accelerator feels heavy, you can perform a fuel system cleaning. Alternatively, try continuing to accelerate to see if the engine speed increases but the vehicle speed does not. If this happens, it may be due to a damaged sensor inside the transmission, which locks the overdrive gear.
