constant brake pedal pressure.
Do not pump the brake pedal
since doing so may defeat the
operation of the ABS system.
The ABS system prevents the lock-up of
wheels which may occur during sudden
braking or braking on slippery road sur-
faces. This helps prevent the loss of
steering control and directional stability
caused by wheel lock-up.
When the ABS system is operating, you
may hear a chattering noise or feel a slight
vibration in the brake pedal. This is normal
when the ABS operates.
The ABS system will not operate when the
vehicle speed is below approximately 6
mph (10 km/h).
& ABS system self-check
You may feel a slight shock in the brake
pedal and hear the operating sound of
ABS from the engine compartment just
after the vehicle is started. This is caused
by an automatic functional test of the ABS
system being carried out and does not
indicate any abnormal condition.

the ignition switch is turned to the "ON"
position and turns off after approximately 2

ing driving.
If these occur, have the ABS system

tunity by your SUBARU dealer.

described in the following, the ABS
system may be considered normal.
