Driving
ABS warning lamp
The warning lamp in the instrument cluster momentarily illuminates
ABS
when the ignition is turned on and the engine is off. If the light does not
illuminate momentarily at start up, remains on or continues to flash, the
ABS needs to be serviced.
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 ABS is
required, apply continuous full force on the brake. The 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.
Rear anti-lock brake system (RABS) (if equipped)
Rear Anti-lock Brake System (RABS) is designed to help you maintain
directional stability in emergency stopping situations. With RABS, the
rear brakes are kept from locking during panic stops; however, the front
wheels can lock because they are not controlled by RABS.
A clicking noise and slight pedal pulsation during RABS braking events
indicates the RABS is functioning. Pedal pulsation coupled with clicking
noise while braking under panic conditions on loose gravel, wet or snowy
roads is normal and indicates proper functioning of the vehicle's RABS. If
the vehicle has continuous vibration or shudder in the steering wheel
while braking, the vehicle should be inspected by a qualified service
technician.
The RABS operates by detecting the onset of rear wheel lockup during
brake applications and compensating for this tendency.
