ANTI-LOCK BRAKING SYSTEM
(ABS)
WARNING
● TheAnti-lock BrakingSystem (ABS)isa
sophisticated device, but it cannot pre-
vent accidents resulting from careless
or dangerous driving techniques. It can
help maintain vehicle control during
braking on slippery surfaces. Remem-
ber that stopping distances on slippery
surfaces will be longer than on normal
surfaces even with ABS. Stopping dis-
tances may also be longer on rough,
gravel or snow covered roads, or if you
are using tire chains. Always maintain a
safe distance from the vehicle in front
of you. Ultimately, the driver is respon-
sible for safety.
● Tire type and condition may also affect
braking effectiveness.
– When replacing tires, install the
specified size of tires on all four
wheels.
– When installing a spare tire, make
surethat itis theproper sizeand type
as specified on the Tire and Loading
Information label. See “Tire and
Loading Information label” in the
“Technical and consumer informa-
tion” section of this manual.
– For detailed information, see
“Wheels and tires” in the “Mainte-
nance and do-it-yourself” section of
this manual.
The Anti-lockBraking System(ABS) controlsthe
brakes so the wheels do not lock during hard
braking or when braking on slippery surfaces.
The system detects the rotation speed at each
wheel and varies the brake fluid pressure to pre-
vent each wheel from locking and sliding. By
preventing each wheel from locking, the system
helps the driver maintain steering control and
helps to minimize swerving and spinning on slip-
pery surfaces.
Using the system
Depress the brake pedal and hold it down. De-
press the brake pedal with firm steady pressure,
but do not pump the brakes. The ABS will oper-
ate to prevent the wheels from locking up. Steer
the vehicle to avoid obstacles.
WARNING
Do not pump the brake pedal. Doing so
may result in increased stopping
distances.
Normal operation
TheABS operatesat speedsabove3-6MPH(5
- 10 km/h). The speed varies according to road
conditions.
When theABS senses that1 or morewheels are
close to locking up, the actuator rapidly applies
and releases hydraulic pressure. This action is
similar to pumping the brakes very quickly. You
may feela pulsationin thebrake pedaland hear a
noise fromunder thehood or feela vibrationfrom
the actuator when it is operating. This is normal
and indicates that the ABS is operating properly.
However, the pulsation may indicate that road
conditions are hazardous and extra care is re-
quired while driving.
Self-test feature
The ABS includes electronic sensors, electric
pumps, hydraulic solenoids and a computer. The
computer has a built-in diagnostic feature that
tests the system each time you start the engine
andmove thevehicle ata lowspeed inforward or
reverse. Whenthe self-test occurs,you mayhear
a“clunk”noiseand/or feelapulsationinthe brake
