5. Release the parking brake switch
.
6. Depress and hold the brake pedal.
7.
Pull the parking brake switch
for
two seconds.
The deactivation of the automatic
operation of the electric parking brake
is confirmed by illuminating on the
cluster. The electric parking brake can
only be applied and released manually.
The deactivation of the automatic
operation of the electric parking brake
is confirmed by illuminating on the
cluster
ð page 42. The electric parking
brake can only be applied and released
manually.
To reactivate the automatic operation,
repeat the steps described above.
Fault
Failure mode of electric parking brake is
indicated by a control indicator
and
by a message displayed on the cluster.
Control indicator
flashes: electric
parking brake is not fully applied or
released. When continuously flashing,
release electric parking brake and try
applying it again.
Brake Assist
If brake pedal is depressed quickly
and forcefully, maximum brake force is
automatically applied.
Operation of brake assist might become
apparent by a pulse in the brake
pedal and a greater resistance when
depressing the brake pedal.
Maintain steady pressure on the brake
pedal as long as full braking is required.
Maximum brake force is automatically
reduced when brake pedal is released.

Regenerative Braking
Warning
In the case of extreme temperatures or
if the high-voltage battery is almost fully
charged, the brake force of the engine
braking may be temporarily reduced. If
the braking force is not sufficient, the
driver must be prepared to use the
brake pedal.
Warning
Depending on the engine braking force
the brake lights are illuminated.
BEV: Regenerative braking generates
electrical energy resulting from engine
braking to charge the high-voltage
battery.
