This small hole plays a significant role, primarily designed for the safety of the car owner. Here are the specific reasons for the existence of this hole: Driving requires the use of airbags: Accidents are inevitable while driving. In the event of a severe collision, the car must deploy an airbag to protect the driver. The airbag effectively shields the driver's head from significant impact, thereby safeguarding the driver's life. The small hole is used to secure the airbag: The airbag is located inside the steering wheel. The small hole under the steering wheel contains a fixing screw, primarily used for replacing the airbag. Simply insert a tool into this hole and turn it to remove the screw.

As a driver with over 20 years of experience, I've noticed that the hole under the steering wheel is primarily designed for safety. Especially in older vehicles, this hole typically serves as an access point for airbags or steering column locks. In the event of a collision, it allows the internal structure of the steering wheel to deploy rapidly, reducing impact force and protecting the driver's chest. When I was younger, I drove cars without this hole, and during accidents, the steering wheel could potentially jam, increasing the risk of injury. The current design with the hole is much safer. Additionally, it's used for routing wires to connect the horn or other buttons, preventing the wires from getting tangled when turning the steering wheel. Checking that the hole is clear every time you get in the car can prevent dust blockages that might cause functional failures. Overall, this hole is part of modern car safety standards, ensuring we drive with greater peace of mind.

I discovered that the most common function of that hole under the steering wheel is for installing the ignition key or anti-theft devices. As an ordinary car owner, I was curious about its purpose when I bought the car, and later learned it's the mounting point for the steering column lock. You need to insert the key to start the engine - without this hole, the key system couldn't be installed. Additionally, in newer car models, this hole might be used to install additional equipment like GPS trackers or alarm systems. I once installed an anti-theft lock myself by drilling into this hole for fixation - super convenient. A friend also mentioned that if dirt accumulates in the hole, the ignition system might malfunction, so regular cleaning is recommended. In short, though small, this hole plays significant roles in starting and anti-theft functions.

Can the Bubbled Rear Window Film Be Removed?

Bubbled rear window film can be removed. Bubbles in the film can obstruct the driver's view, and timely removal and replacement can enhance driving safety. Bubbles in the rear window film can result from improper installation techniques or prolonged heating, causing expansion and contraction that leads to bubbles. It is recommended to remove and reapply the film. Areas for car window film application include: front windshield film, rear windshield film, side window film, and quarter window film. The benefits of car window film are: 1. Heat insulation and sun protection to reduce interior temperature; 2. UV blocking to slow down the aging of car interiors; 3. Preventing injuries from accidental glass shattering; 4. Creating a private space; 5. Reducing air conditioning consumption; 6. Enhancing aesthetics; 7. Reducing glare.

Why Can't I Engage Reverse Gear in a Manual Transmission?

The reasons for being unable to engage reverse gear in a manual transmission are: 1. The clutch is not fully depressed; 2. The transmission has malfunctioned; 3. The gear teeth happen to align; 4. The car temperature is low, and the transmission oil is not fully lubricated; 5. The vehicle speed and gear position do not match. A manual transmission car uses a manual shift mechanical transmission to adjust the vehicle speed, where the driver manually moves the gear lever to change the gear meshing position inside the transmission, altering the gear ratio to achieve speed change. The gear positions in a manual transmission car are: 1. 1st gear is the starting gear: used for vehicle start-up; 2. 2nd gear is the passing gear: used for navigating complex road surfaces and handling complex situations; 3. 3rd gear is the transition gear: used for low-speed driving on urban roads; 4. 4th gear is the driving gear: used for prolonged high-speed driving; 5. 5th gear is the high-speed gear: used for long-distance highway driving.

What does Dual VVT mean?

Dual VVT separately controls the engine's intake and exhaust systems. During rapid acceleration, the intake VVTi advances the intake timing and increases valve lift, while the exhaust VVTi delays the exhaust timing. This effect is similar to a small turbocharger, effectively enhancing engine power. Additionally, the increased air intake ensures more complete combustion of gasoline, achieving the goal of low emissions. The maintenance methods for a Dual VVT engine are: 1. Maintain good crankcase ventilation; 2. Regularly change the oil and filter; 3. Periodically clean the crankcase; 4. Regularly clean the radiator; 5. Periodically clean the fuel system; 6. Use lubricants appropriately.

Where to Add Transmission Fluid for a Car?

There are two bolts on the transmission housing of a car, one on the left and one on the right. The upper bolt is the oil filler hole; simply unscrew it when you need to add transmission fluid. The function of transmission fluid is to ensure smooth gear shifting, lubricate internal transmission components, and prevent damage to the transmission during gear changes. The steps for changing transmission fluid are as follows: 1. Start the engine to warm it up, allowing the transmission to reach operating temperature. Remove the drain bolt and collect the old fluid from the transmission. 2. Once the old fluid has completely drained, open the oil pan, replace the transmission filter, reinstall the oil pan and drain plug. 3. Add new transmission fluid, start the car, and shift through all gears. 4. Check if the automatic transmission fluid level is normal and make adjustments as needed.

Where is the water temperature gauge displayed on the Volkswagen Jetta?

The water temperature gauge on the Volkswagen Jetta is displayed in the central electronic display of the instrument panel. When the car's water temperature is too high, the water temperature warning light on the instrument panel will illuminate to alert the driver. The water temperature indicator is used to show the temperature of the coolant in the engine, with some models using colors to indicate different conditions: blue indicates the water temperature is too low, red indicates it is too high, and no light means it is normal. Taking the 2020 Jetta VS5 as an example, its body dimensions are 4419mm in length, 1841mm in width, and 1616mm in height, with a wheelbase of 2630mm. This model is equipped with a 1.4L inline 4-cylinder turbocharged engine, delivering a maximum horsepower of 150PS, a maximum power of 110kW, and a maximum torque of 250Nm, paired with a 6-speed automatic transmission.
