WARNING:
If you are driving down a long or steep hill, shift to
a lower gear. Do not apply your brakes continuously, as they may
overheat and become less effective.
If brakes do not grip well
•
If you have been driving through deep water, gently apply the brakes
several times while the vehicle is moving slowly.
•
Let the brakes cool if you have been using them excessively, as in
mountain driving or after several fast, high-speed stops.
•
Check brake linings for excessive wear.
Hydraulic brake booster system (HydroBoost)
The HydroBoost systems receive fluid pressure from the power steering
pump to provide power assist during braking.
The HydroBoost booster includes a pneumatic accumulator that holds a
reserve of power steering fluid under pressure that will provide two or
more power-assisted brake applications in the event of power steering
fluid pressure loss. The accumulator will also deliver a limited number of
power-assisted brake applications when the engine is off.
The HydroBoost’s accumulator reserve provides reduced braking power,
and the number of stops is limited (depending on the severity and
duration of the brake applications), so the vehicle should be operated
under these conditions with caution, and only to seek service repair and
remove the vehicle from the roadway.
Under normal operating conditions, noise of the fluid flowing through the
booster may be heard whenever the brake is applied. This is normal and
should be no reason for concern.
If braking performance or pedal response becomes very poor, even when
the pedal is strongly applied, this may indicate the presence of air in the
hydraulic system or fluid leakage. Safely stop the vehicle as soon as
possible and seek service immediately.
If the brake fluid warning light in
the instrument cluster remains
illuminated after engine start-up,
and an audible tone is heard while the light is illuminated, this indicates
a system failure in the brake system. Stop the vehicle as soon as safely
possible and seek service immediately.
