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.

RABS warning lamp

The

ABS

warning lamp in the instrument cluster momentarily illuminates

when the ignition is turned to the ON position. 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 RABS

• In an emergency, applying full pressure may cause the front wheels to

lock. If the front brakes lock, the vehicle cannot be steered. You

should apply the brakes with steadily increasing force, as if

“squeezing” the brakes. If you feel the front wheels begin to lock,

momentarily release the pedal and repeat the “squeeze” technique.

• We recommend that you familiarize yourself with how the RABS

performs. However, avoid unnecessary risks.

Four-wheel anti-lock brake system (ABS) (if equipped)

On vehicles equipped with a four–wheel anti-lock braking system (ABS),

a noise from the hydraulic pump motor and pulsation in the pedal may

be observed during ABS braking events. Pedal pulsation coupled with

noise while braking under panic conditions or on loose gravel, bumps,

wet or snowy roads is normal and indicates proper functioning of the

vehicle’s anti-lock brake system. If the vehicle has continuous vibration

or shudder in the steering wheel while braking, the vehicle should be

inspected by a qualified service technician.
