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.
6-26
• 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.
NOTICE
• Do not continue depressing the brake
pedal if the " " indicator is OFF. The
battery may be discharged.
• Noise and vibration generated during
braking is normal.
• Under normal operation, electric brake
pump noise and motor vibration may
occur temporarily in below cases.
- When the pedal is depressed
suddenly.
- When the pedal is repeatedly
depressed in short intervals.
- When the ABS function is activated
while braking.
