It may be caused by a short circuit of the wiring harness to the positive pole, or the parking brake control unit may be faulty. Here is the relevant introduction: 1. Electronic handbrake: The electronic handbrake is also known as the electronic parking brake system. The Electronic Parking Brake (EPB) integrates the temporary braking during driving and the long-term braking after parking, and realizes the parking braking technology through electronic control. 2. Working principle: The electronic handbrake is a technology that realizes parking braking through electronic control. Its working principle is the same as that of the mechanical handbrake, both of which use the friction generated by the brake disc and the brake pad to control the parking brake, except that the control method has changed from the previous mechanical handbrake lever to an electronic button.

Where is the fuel filler switch on the Cruze?

The fuel filler door switch of the Cruze is located below the driver's seat on the left side, within reach of the left hand. There are usually two buttons: one for opening the trunk and the other for opening the fuel filler door. The fuel filler door switch has a fuel pump icon, and you can lift it upwards to open the fuel filler door. The Chevrolet Cruze uses an integrated central locking system. As long as the car door is unlocked, the fuel filler door can be opened. When the vehicle speed exceeds 8 km/h, the fuel filler door will automatically lock like the car doors. Below are the specific details about the Cruze's fuel filler door: 1. The fuel filler door of the Cruze is located on the right side, which is the passenger side, specifically below the driver's seat on the left. The Chevrolet Cruze uses an integrated central locking system. 2. To open the fuel filler door, first turn off the engine, then go to the fuel filler door. Use the car key to unlock it, and press the back of the fuel filler door to open it. Since the Cruze does not have a separate fuel filler door switch, it is integrated with the central locking system.

What does 'several oil' mean when referring to cars?

When people say 'several oil' in relation to cars, it refers to the amount of gasoline consumed per kilometer driven by the vehicle. Below are some relevant explanations: 1. Fuel consumption per 100 kilometers: This is an indicator for vehicles. Standardized fuel consumption is a statistical norm. The slower a vehicle drives within its economical speed range, the higher the fuel consumption per 100 kilometers will be, and the opposite is true when exceeding the economical speed. Since most vehicles approach their economical speed at around 90 km/h, the fuel consumption is usually measured as the fuel consumption per 100 kilometers at 90 km/h. 2. Calculating by hourly fuel consumption: Regardless of the speed at which the vehicle is traveling, the hourly fuel consumption remains the same. When calculating fuel consumption for highways and engineering transportation, the first two norms are not suitable; using hourly fuel consumption is more accurate. The formula for hourly fuel consumption is: Fuel consumption per 100 kilometers / 100 * limit speed * 0.8 (the limit speed is the highest safe speed).

How to Perform Parallel Parking with a Manual Transmission?

Here are the steps for performing parallel parking with a manual transmission: 1. Method One: First, adjust the rearview mirrors properly before entering the test area (marked by a pole with the project name on the right side of the road; once the car passes the pole, the system will announce "parallel parking" and start timing). You can stop to make adjustments before entering. 2. Method Two: Adjust the rearview mirrors as follows: For the left mirror, position it so that the distant horizon is centered vertically, and adjust the horizontal position so that the car body occupies one-fourth of the mirror's surface. For the right mirror, adjust it so that the ground occupies about two-thirds of the mirror vertically, and similarly, position the car body to occupy one-fourth horizontally. 3. Method Three: Start moving forward with the left turn signal on. Drive at half-clutch, aligning the 12 o'clock position of the steering wheel with the right-turn white arrow in front of the parking line, moving slowly and parallel while making minor adjustments. When you see the front boundary line of the parking space in the right rearview mirror, press the clutch and brake to stop.

How to Repair Branch Scratches?

Methods for repairing branch scratches are as follows: 1. Use scratch wax: Apply the wax with a polishing sponge in a clockwise or counterclockwise motion over the scratched area, then use a polishing wax. 2. Use toothpaste for repair: Gently apply toothpaste to minor scratches and wipe with a soft cloth in a counterclockwise motion. Additional information: Exposure to sunlight and rain can worsen small scratches and damage the car's paint, as rainwater can seep through these "wounds" and accelerate rusting. However, scratches that only affect the car's appearance and not driving safety can be addressed later if time is limited. In contrast, scratches or wear on tires, which are crucial for driving safety, require thorough inspection and immediate attention to ensure vehicle safety.

What to Do When Random Selection Attempts Are Exhausted?

If you have used up all random and self-compiled license plate selection attempts on the Traffic Management 12123 platform, the only option left is to visit the vehicle management office for a 50-choose-1 selection method. However, the probability of obtaining a satisfactory license plate number through this method is relatively low. Additional Information: 1. Traffic Management 12123 Selection Rules: The pre-selection period is from 8:00 AM to 10:00 PM daily. There are a total of 20 self-compiled attempts, and only number segments released for more than 7 days are eligible for self-compilation. Random selection allows 5 attempts, with 10 numbers per attempt and a 90-second selection time per batch. 2. Online Selection Notes: If you have selected a license plate number online, it is mandatory to complete the registration process within 5 working days. Failure to do so will not only invalidate the selected number but also prohibit the use of online selection services for two years.
