BRAKING SYSTEM

Power-assist brakes

Your vehicle has power-assisted brakes
that adjust automatically through normal
usage.
In the event of a vehicle power failure,
the power assist for the brakes will not
work. You can still stop your vehicle, but
it will require greater force and increased
pedal travel than normal. The stopping
distance, however, will be longer than
with power brakes.
Information
• When the brake pedal is depressed
under certain driving conditions
or weather conditions, you may
temporarily hear a noise. This is
normal and does not indicate a problem
with your brakes.
• While driving on a road with deicing
chemicals, brake noise or abnormal
tire wear may occur due to deicing
chemicals. In a safe traffic condition,
additionally apply the brakes to remove
deicing chemicals on the brake discs
and pads.

WARNING
Take the following precautions:
• Do not drive with your foot resting
on the brake pedal. This will create
abnormal high brake temperatures,
excessive brake lining and pad wear,
and increased stopping distances.
So increase the regeneration braking
level with the left paddle shift lever
to decrease the speed.
• When descending down a long or
steep hill, use the paddle shifter to
increase the regeneration braking
level in order to decrease your
speed without using the brake
pedal excessively. Applying the
brakes continuously will cause
the brakes to overheat and could
result in a temporary loss of braking
performance.
• Wet brakes may impair the vehicle's
ability to safely decelerate. Because
wet brakes increase braking distance
and cause noise troubles, select 0
step of the regenerative braking
system and depress the brake pedal
around 10 times, with keeping the
safe distance from other vehicles,
lightly in order to dry the braking
system. Such procedure may
decrease the driving distance by
restraining the regenerative braking
system, which is not a system
malfunction. Inspect the braking
system after car wash or driving over
wet road conditions.
