Brake System
▼Foot Brake
This vehicle has power-assisted brakes
that adjust automatically through
normal use.
Should power-assist fail, you can stop
by applying greater force than normal
to the brake pedal. But the distance
required to stop will be greater than
usual.
WARNING
Do not coast with the engine stalled
or turned off, find a safe place to stop:
Coasting with the engine stalled or
turned
off is dangerous. Braking will
require more effort, and the brake's
power-assist could be depleted if you
pump the brake. This will cause longer
stopping distances or even an
accident.
Shift to a lower gear when going
down steep hills:
Driving with your foot continuously on
the brake pedal or steadily applying
the brakes for long distances is
dangerous. This causes overheated
brakes, resulting in longer stopping
distances or even total brake failure.
This could cause loss of vehicle control
and a serious accident. Avoid
continuous application of the brakes.
Dry off brakes that have become wet
by driving slowly, releasing the
accelerator pedal and lightly applying
the brakes several times until the
brake performance returns to normal:
Driving with wet brakes is dangerous.
Increased stopping distance or the
vehicle pulling to one side when
braking could result in a serious
accident. Light braking will indicate
whether the brakes have been
affected.
CAUTION
Do not drive with your foot held on
the brake pedal. Doing so could
result in the following:
The brake parts will wear out more
quickly.
The brakes can overheat and
adversely
affect brake
performance.
Always depress the brake pedal with
the right foot. Applying the brakes
with the unaccustomed left foot
could slow your reaction time to an
emergency situation resulting in
insufficient braking operation.
Wear shoes appropriate for driving in
order to avoid your shoe contacting
the brake pedal when depressing the
accelerator pedal.
