Emergency braking function
If the car is braked during driving, but the foot brake is faulty or blocked, the electronic
handbrake switch can be applied continuously to brake and park the car forcedly. At the
time, the indicator on the dashboard will be turned on, an alarm will sound and “Electronic
Parking Not Released” will be displayed.
Warning
●
Must avoid the application of the electronic handbrake as much as possible; the
emergency braking function can only be activated only when the foot brake is faulty
or a the brake pedal is blocked.
●
Because the electronic handbrake cannot exceed the physical limit of road
adhesion, must avoid application of emergency braking function on corner sections,
dangerous sections, traffic jamming sections under bad weather conditions;
otherwise, it may cause driving instability, slipping or deviation, resulting in an
accident.
Invalid release function
■
When the electronic handbrake is not released manually, must press and hold
the switch for more than 2s. If the electronic handbrake can be released, please
drive the car to the nearest service station as soon as possible, to check the brake
pedal switch signal and related parts and lines; if it still cannot be released, it is
recommended to contact BYD Auto Authorized Service Station immediately.
■
During driving process, ESP system should be operated normally. If the brake is
blocked or faulty, CDP (Deceleration Control Function) function can be used for
emergency braking, with the specific operation as follows:
●
If only the electronic handbrake switch is applied, the brake deceleration should
be 0.4g;
●
If the electronic handbrake switch is applied and the brake pedal is depressed at
the same time, the brake decelerates should be 0.8g.
■
Do not apply EPB for forced braking if the brake is not faulty or the brake pedal is not
blocked.
