Is the Corolla's Electronic Parking Brake Automatic?

The Corolla's electronic parking brake is not automatic. Here’s how to use the electronic parking brake in the new Corolla: 1. After starting, the vehicle's computer sets the engine to idle, and the brake motor engages the brake pads to apply the brake. 2. Before the car starts, the electronic parking brake cannot be released; check if the battery is dead or if the vehicle's computer has frozen. 3. If the battery is dead, replace the motor; if the computer has frozen, restart the system. Relevant information about the electronic parking brake is as follows: 1. The electronic parking brake is a technology that achieves parking braking through electronic control. Its working principle is the same as that of a mechanical handbrake—both rely on the friction generated between the brake disc and brake pads to control parking braking. The only difference is that the control method has changed from a mechanical handbrake lever to an electronic button. 2. The electronic parking brake is also known as the Electronic Parking Brake (EPB) system. The EPB system integrates the temporary braking function during driving with the long-term parking braking function and achieves parking braking through electronic control.

What to Do If the Cruze Trunk Switch Fails?

Solutions for a malfunctioning Cruze trunk switch: If the trunk can be opened using the remote control, it indicates that the trunk switch is damaged. If the remote control also fails to open it, the lock block may be damaged. There is an emergency escape switch above the trunk lock; pulling it down can open the trunk. Below are the symptoms of a trunk that won't open: 1. The Cruze trunk door is operated remotely. When using the remote to open the door, remember to long-press the trunk unlock button to open it. Of course, when pressing the trunk unlock button, the central locking system should also unlock. If the remote can open it but the trunk still won't open, it may be due to rainwater entering the trunk switch area causing corrosion, which is a relatively common issue. The only solution is replacement, which can be done at a 4S shop. 2. If neither the remote nor manual methods work, it could be due to a damaged trunk lock block, requiring replacement. Additionally, there is a master switch for the trunk lock above the lock block; it's also important to check if the trunk's failure to open is caused by the master switch being turned off.
