(Continued)
The safety features of an ABS (or
ESC) equipped vehicle should not be
tested by high speed driving or cor‐
nering. This could endanger the
safety of yourself or others.
The ABS continuously senses the speed
of the wheels. If the wheels are going
to lock, the ABS system repeatedly
modulates the hydraulic brake pressure
to the wheels.
When you apply your brakes under
conditions which may lock the wheels,
you may hear a tik-tik’’ sound from
the brakes, or feel a corresponding sen‐
sation in the brake pedal. This is normal
and it means your ABS is active.
In order to obtain the maximum benefit
from your ABS in an emergency situa‐
tion, do not attempt to modulate your
brake pressure and do not try to pump
your brakes. Press your brake pedal as
hard as possible or as hard as the sit‐
uation warrants and allow the ABS to
control the force being delivered to the
brakes.
NOTICE
A click sound may be heard in the
engine compartment when the vehi‐
cle begins to move after the engine
is started. These conditions are nor‐
mal and indicate that the anti-lock
brake system is functioning proper‐
ly.
• Even with the anti-lock brake sys‐
tem, your vehicle still requires suffi‐
cient stopping distance. Always main‐
tain a safe distance from the vehicle
in front of you.
• Always slow down when cornering.
The anti-lock brake system cannot
prevent accidents resulting from ex‐
cessive speeds.
• On loose or uneven road surfaces, op‐
eration of the anti-lock brake system
may result in a longer stopping dis‐
tance than for vehicles equipped with
a conventional brake system.
W-78
CAUTION
• If the ABS warning light is on and
stays on, you may have a problem
with the ABS. In this case, howev‐
er, your regular brakes will work
normally.
