braking with loss of front braking traction.
ABS warning lamp
ABS
TheABSwarning lamp in the instrument cluster momentarily illuminates
when the ignition is turned to the ON position. If the light remains on
after the vehicle is started, continues to flash or fails to illuminate, have
the system serviced immediately. With the ABS light on, the anti-lock
brake system is disabled and normal braking is still effective unless the
brake warning light also remains illuminated.
With the ABS light on, the anti-lock
brake system is disabled and normal
braking is still effective unless the
brake warning light also remains
illuminated with parking brake
released. (If your brake warning lamp illuminates, have your vehicle
serviced immediately.)
Using ABS
•In an emergency or when maximum efficiency from the four wheel
ABS is required, apply continuous force on the brake. The four wheel
ABS will be activated immediately, thus allowing you to retain full
steering control of your vehicle and, providing there is sufficient
space, will enable you to avoid obstacles and bring the vehicle to a
controlled stop.
•The Anti-Lock system does not decrease the time necessary to apply
the brakes or always reduce stopping distance. Always leave enough
room between your vehicle and the vehicle in front of you to stop.
•We recommend that you familiarize yourself with this braking
technique. However, avoid taking any unnecessary risks.
Hydraulic brake booster system (Hydroboost or Hydromax)
The Hydroboost and Hydromax systems receive fluid pressure from the
power steering pump to provide power assist during braking.
The Hydromax booster receives backup pressure from the reserve
system electric pump whenever the fluid in the power steering system is
not flowing. When the engine is OFF, the pump will turn on if the brake
pedal is applied, or if the ignition is turned to the ON position.

The sound of the pump operating may be heard by the driver, but this is
a normal characteristic of the system.
The reserve system provides reduced braking power, so the vehicle
should be operated under these conditions with caution, and only to seek
service repair and remove the vehicle from the roadway.
For Hydromax-equipped vehicles operating under normal conditions, the
noise of the fluid flowing through the booster may be heard whenever
the brake is applied. This condition is normal. Vehicle service is not
required.
If braking performance or pedal response becomes very poor, even when
the pedal is strongly depressed, it may indicate the presence of air in the
hydraulic system or leakage of fluid. Stop the vehicle safely as soon as
possible and seek service immediately.
Parking brake
Apply the parking brake whenever
the vehicle is parked. Push pedal
downward to set the parking brake.
The BRAKE warning lamp in the
instrument cluster illuminates and
remains illuminated (when the
ignition is turned ON) until the
parking brake is released.
Always set the parking brake fully and make sure the gearshift is
latched in P (Park). Turn off the ignition whenever you leave
your vehicle.
