108 4-3 Application of Driving Auxiliary Functions
Emergency brake function

When braking is needed in the vehicle travelling process but it is found that the
service brake has been failed or blocked, keep pulling up to forcibly brake the
vehicle until it stops. When this operation is finished, the indicator on the
instrument will light up and the instrument will produce an alarm sound and display the
message of "EPB deactivated".
WARNING
Avoid forcible braking by applying the EPB. The emergency brake function can be
activated only in emergency cases, such as failure of foot brake and blocking of brake
pedal.
As the EPB cannot go beyond the physical limit of road adhesion, the activation of
emergency brake function may result in drift, sideslip or deflection of the vehicle when
the vehicle passes through bends, dangerous and heavy-traffic road sections or when
the vehicle is driven under severe weather conditions. Therefore, please use this
function with care to avoid accidents.
Failure release function

When manually releasing the EPB fails, keep pressing for more than 2s. If the
EPB can be released, drive to the nearest repair shop as soon as possible to check
the switching signal of brake pedal and the relevant parts and lines. If the EPB cannot
be released after doing so, immediately contact a BYD authorised service provider.

If only EPB switch is pulled up, the braking effect will be weak; if the EPB switch is
pulled up and meanwhile the brake pedal is depressed, the braking effect will be
obvious. Avoid forcible braking by applying the EPB. The emergency brake function
can be activated only in emergency cases, such as failure of foot brake and blocking
of brake pedal.
