Driving your vehicle

Anti-lock brake system (ABS)
(if equipped)
ABS (or ESC) will not prevent accidents
due to improper or dangerous driving
maneuvers. Even though vehicle control
is improved during emergency braking,
always maintain a safe distance between
you and objects ahead. Vehicle speeds
should always be reduced during
extreme road conditions.
The vehicle should be driven at reduced
speeds in the following circumstances:
• When driving on rough, gravel or
snow-covered roads
• When driving on roads where the road
surface is pitted or has different sur-
face heights.
Driving in these conditions increases the
stoppinZg distance for your vehicle.
The ABS continuously senses the speed
of the wheels. If the wheels are going to
lock, the ABS system repeatedly modu-
lates the hydraulic brake pressure to the
wheels.
When you apply your brakes under con-
ditions which may lock the wheels, you
may hear a “tik-tik’’ sound from the
brakes, or feel a corresponding sensation
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 situa-
tion allows the ABS to control the force
being delivered to the brakes.
✽ ✽
NOTICE
A click sound may be heard in the
engine compartment when the vehicle
begins to move after the engine is start-
ed. These conditions are normal and
indicate that the anti-lock brake system
is functioning properly.
• Even with the anti-lock brake system,
your vehicle still requires sufficient
stopping distance. Always maintain a
safe distance from the vehicle in front
of you.
• Always slow down when cornering.
The anti-lock brake system cannot pre-
vent accidents resulting from exces-
sive speeds.
• On loose or uneven road surfaces,
operation of the anti-lock brake system
may result in a longer stopping dis-
tance than for vehicles equipped with a
conventional brake system.
