Power brakes
Your vehicle has power-assisted brakes
that adjust automatically through normal
usage.
If the engine is not running or is turned
off while driving, the power assist for
the brakes will not work. You can still
stop your vehicle by applying greater
force to the brake pedal than typical.
The stopping distance, however, will be
longer than with power brakes.
When the engine is not running, the
reserve brake power is partially depleted
each time the brake pedal is applied.
Do not pump the brake pedal when the
power assist has been interrupted.
Pump the brake pedal only when
necessary to maintain steering control
on slippery surfaces.
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.
• When descending a long or steep
hill, shift to a lower gear and avoid
continuous application of the brakes.
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 slow down; the
vehicle may also pull to one side
when the brakes are applied.
Applying the brakes lightly will
indicate whether they have been
affected in this way. Always test your
brakes in this fashion after driving
through deep water. To dry the
brakes, lightly tap the brake pedal to
heat up the brakes while maintaining
a safe forward speed until brake
performance returns to normal.
Avoid driving at high speeds until the
brakes function correctly.
Disc brakes wear indicator
When your brake pads are worn and new
pads are required, you will hear a high
pitched warning sound from your front
or rear brakes. You may hear this sound
come and go or it may occur whenever
you depress the brake pedal.
Please remember some driving
conditions or climates may cause a
brake squeal when you first apply (or
lightly apply) the brakes. This is normal
and does not indicate a problem with
your brakes.
NOTICE
To avoid costly brake repairs, do not
continue to drive with worn brake pads.
i Information
Always replace brake pads as complete
front or rear axle sets.
