What does the AVH Auto Hold System mean

Auto Hold refers to an automatic braking function. After activating this feature, such as when stopping at a traffic light, it eliminates the need to pull the handbrake, simplifying operations by avoiding the use of manual or electronic parking brakes. For automatic transmission models, it also reduces the need for frequent shifting between D to N or D to P. The functions of the Auto Hold system include: 1. Preventing rollback: When stopping briefly at a traffic light, the system automatically applies the brakes to the wheels after the vehicle comes to a complete stop to prevent rolling. 2. Preventing backward sliding: During uphill starts, the system automatically brakes to prevent backward sliding, and releases the wheels automatically when starting to move forward. 3. Automatic braking: Some models automatically apply the brakes to the wheels when the vehicle is parked and locked, eliminating the need to pull the handbrake. Working principle of Auto Hold: When the vehicle is temporarily stopped and needs to restart shortly after, the parking function is handled by the ESP-controlled brakes. The computer uses a series of sensors to measure the vehicle's levelness and wheel torque, determines any tendency for the vehicle to move, and applies an appropriate braking force to the wheels to keep the vehicle stationary. This braking force is just enough to prevent movement without being excessive, ensuring a smooth start when the accelerator is pressed again. If the temporary stop exceeds a certain duration, the braking system switches to mechanical rear-wheel parking (activating the electronic parking brake) instead of the previous four-wheel hydraulic braking. When the vehicle is ready to move forward, the electronic system detects the accelerator pedal pressure and, for manual transmission models, the clutch pedal travel to determine whether to release the brakes.

How to Handle a Car That Hasn't Been Driven for a Long Time?

Methods for handling a car that hasn't been driven for a long time: 1. Thoroughly clean the car's paint and interior before parking to prevent damage to the paint during storage. After cleaning, it is recommended to wax the car for better protection; 2. Remove the car battery to maintain sufficient charge; 3. Protect the tires. If the car remains stationary for a long time, the part of the tires in contact with the ground may deform or lose air. The owner should move the vehicle or drive it for a while; 4. Check the fluids. Cars have various fluids, and if the vehicle is parked for an extended period, it's necessary to inspect the condition of all fluids and replace them in time to prevent deterioration; 5. Find a suitable parking spot, cover the car with a car cover to properly protect the paint.

What are the symptoms of a broken engine turbocharger?

Symptoms of a broken engine turbocharger: The car's exhaust pipe emits blue or white smoke, decreased power, increased fuel consumption, increased engine oil, and unstable turbo pressure. When the car is idling, the exhaust pipe emits blue or white smoke due to poor sealing of the turbocharger impeller shaft. When the turbocharger malfunctions, the car's power will noticeably decrease, and fuel consumption will rise accordingly. If the exhaust gas recirculation pipe is blocked, stepping on the accelerator will not only produce blue smoke but also accelerate engine oil consumption. It is important to note that after starting the engine, you should not drive immediately. Instead, let the engine idle for 2 to 3 minutes to allow the turbocharger to be fully lubricated before driving. During long-distance driving, if the engine has been running at high speed for an extended period, do not turn it off immediately. Sudden shutdown can cause the residual oil in the turbocharger to overheat and damage the bearings.

Is the middle pedal the accelerator or the brake?

The middle pedal is the brake, and the one on the right is the accelerator. Manual transmission cars have three pedals: the left one is the clutch, the middle one is the brake, and the right one is the accelerator. Automatic transmission cars have two pedals: the left one is the brake, and the right one is the accelerator. The brake is a crucial system in a car, mainly composed of the vacuum booster, master cylinder, wheel cylinder, and brake pads. When the driver presses the brake pedal, the vacuum booster provides assistance, the master cylinder pushes the wheel cylinder through brake fluid, and the wheel cylinder then presses the brake pads against the brake disc, slowing the car down. Brake fluid is a liquid that easily absorbs moisture. If the brake fluid contains too much water, it can reduce braking force and increase stopping distance, affecting the car's stability and safety. It is recommended that car owners replace the brake fluid regularly.
