Driving your vehicle
Power brakes
Your vehicle has power-assisted
brakes that adjust automatically
through normal usage.
If the hybrid system is not on 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 dis-
tance, however, will be longer than
with power brakes.
When the hybrid system is not on,
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 con-
trol on slippery surfaces.Wet brakes may impair the vehicle’s
ability to safely slow down; the vehi-
cle 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 fash-
ion after driving through deep water.
To dry the brakes, apply them lightly
while maintaining a safe forward
speed until brake performance
returns to normal.
✽ ✽
NOTICE
Do not depress the brake pedal con-
tinuously without the " " indica-
tor ON. The battery may be dis-
charged.
BRAKE SYSTEM
WARNING- Steep hill
braking
Avoid continuous application of
the brakes when descending a
long or steep hill by shifting to a
lower gear. Continuous brake
application will cause the
brakes to overheat and could
result in a temporary loss of
braking performance.
WARNING- HEV driving down hill
Do not turn off the Hybrid sys-
tem while going down a hill. The
brake booster may not work
sufficiently and the braking dis-
tance may be longer.
CAUTION- Brake Pedal
Do not drive with your foot rest- ing on the brake pedal. This willcreate abnormally high braketemperatures which can causeexcessive brake lining and padwear.

In the event of brake failure
If service brakes fail to operate while
the vehicle is in motion, you can
make an emergency stop with the
parking brake. The stopping dis-
tance, however, will be much greater
than normal.
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 brakes or rear brakes. You
may hear this sound come and go or
it may occur whenever you depress
the brake pedal.
Please remember that some driving
conditions or climates may cause a
brake squeal when you first apply (or
lightly apply) the brakes. This is nor-
mal and does not indicate a problem
with your brakes.
Always replace the front or rear
brake pads as pairs.
WARNING- Parking
brake
Avoid applying the parking
brake to stop the vehicle while it
is moving except in an emer-
gency situation. Applying the
parking brake while the vehicle
is moving at normal speeds can
cause a sudden loss of control
of the vehicle. If you must use
the parking brake to stop the
vehicle, use great caution in
applying the brake.
WARNING- Brake wear
Do not ignore high pitched wear
sounds from your brakes. If you
ignore this audible warning, you
will eventually lose braking per-
formance, which could lead to a
serious accident.
CAUTION- Replace brake pads
Do not continue to drive withworn brake pads. Continuing todrive with worn brake pads candamage the braking system andresult in costly brake repairs.
