CAUTION
D
Do not pump the brake pedal if the
engine stalls. Each push on the
pedal uses up your reserved vacu-
um.
D
Even if the power assist is com-
pletely lost, the brakes will still
work. But you will have to push the
pedal hard, much harder than nor-
mal. And your braking distance will
be longer.
ANTI–LOCK BRAKE SYSTEM
(with "ABS" warning light)
The anti–lock brake system is designed
to help prevent lock–up of the wheels
during a sudden braking or braking on
slippery road surfaces. This assists in
providing directional stability and steer-
ing performance of the vehicle under
these circumstances.

'03 HIGHLANDER_U (L/O 0208)
Effective way to press the ABS brake
pedal: When the anti–lock brake system
function is in action, you may feel the
brake pedal pulsating and hear a noise.
In this situation, to let the anti–lock
brake system work for you, just hold the
brake pedal down more firmly. Do not
pump the brake in a panic stop. This
will result in reduced braking performan-
ce.
The anti–lock brake system becomes op-
erative after the vehicle has accelerated
to a speed in excess of approximately 10
km/h (6 mph). It stops operating when the
vehicle decelerates to a speed below
approximately 5 km/h (3 mph).
Depressing the brake pedal on slippery
road surfaces such as on the manhole
cover, the steel plate under the construc-
tion, joints in the bridge, etc. on a rainy
day tends to activate the anti–lock brake
system.
You may hear a click or motor sound in
the engine compartment for a few seconds
when the engine is started or just after
the vehicle is started. This means that the
anti–lock brake system is in the self–
check mode, and does not indicate a mal-
function.
2003 HIGHLANDER from Aug. '02 Prod. (OM48441U)
When the anti–lock brake system is ac-
tivated, the following conditions may
occur. They do not indicate a malfunc-
tion of the system:
D
You may hear the anti–lock brake sys-
tem operating and feel the brake pedal
pulsating and the vibrations of the ve-
hicle body and steering wheel. You
may also hear the motor sound in the
engine compartment even after the ve-
hicle is stopped.
D
At the end of the anti–lock brake sys-
tem activation, the brake pedal may
move a little forward.
