HOW THE ABS WORKS
A computer continuously monitors wheel
speed. The computer compares the
changes in wheel speed when braking. If
the wheels slow suddenly, indicating a
skidding situation, the computer will
change braking pressure several times
each second to prevent the wheels from
locking. When you start your vehicle af-
ter a stop you may hear a momentary mo-
tor noise as the system checks itself.
The ABS may not work
properly if tires or wheels
other than those specified in the own-
er’s manual are used. This is because
the ABS works by comparing changes
in wheel speed. When replacing tires
or wheels, use only the size and type
specified in this owner’s manual.
WARNING
ELECTRONIC STABILITY
PROGRAM (ESP
®
)
(if equipped)
ESP
®
is a registered trademark of Daim-
lerChrysler AG.
The Electronic Stability Program (ESP
®
)
helps to control the vehicle during cor-
nering if the vehicle is understeering or
oversteering. It also assists you in main-
taining traction while accelerating on loose
or slippery road surfaces. It does this by
regulating the engine’s output, and by se-
lectively applying the brakes. In addition,
ESP
®
helps to avoid skidding by controlling
braking pressure.
The ESP
®
cannot enhance
the vehicle’s driving stabili-
ty in all situations and does not con-
trol your vehicle’s entire braking sys-
tem. The ESP
®
cannot prevent acci-
dents, including those resulting from
excessive speed in turns, or hy-
droplaning. Only a safe and attentive
driver can prevent accidents. The ca-
pabilities of an ESP
®
- equipped ve-
hicle must never be used as a substi-
tute for careful driving.
WARNING
The ESP
®
has the following three systems:
STABILITY CONTROL SYSTEM
The vehicle stability control system helps
provide integrated control of systems such
as anti- lock brakes, traction control, en-
gine control, etc. This system automati-
cally controls the brakes and engine to
help prevent the vehicle from skidding
when cornering on a slippery road surface
or when turning the steering wheel
abruptly.
TRACTION CONTROL SYSTEM
The traction control system automatical-
ly helps prevent the spinning of wheels
when the vehicle is started or accelerated
on slippery road surfaces. The system op-
erates only if it senses that some of the
wheels are spinning or beginning to lose
traction. When this happens, the system
operates the front or rear brakes and re-
duces engine power to limit wheel spin.
NOTE You may hear a clicking sound in
the engine compartment for a few seconds
when you start the engine or just after the
vehicle begins to move. This means that
the above systems are in the self-check
mode. This sound does not indicate a mal-
function.
