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 or
when you accelerate after a hard stop, you
may hear a momentary motor or clicking
sound as the system resets or checks
itself.
Electronic Stability Program
(ESP
®
)
ESP
®
is a registered trademark of
DaimlerChrysler AG.
The Electronic Stability Program (ESP
®
)
helps to control the vehicle during corner-
ing if the vehicle is understeering or over-
steering. It also assists you in maintaining
traction while accelerating on loose or slip-
pery road surfaces. It does this by regulat-
ing the engine’s output, and by selectively
applying the brakes. In addition, ESP
®
helps to avoid skidding by controlling brak-
ing pressure.
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, engine
control, etc. This system automatically
controls the brakes and engine to help pre-
vent the vehicle from skidding when cor-
nering on a slippery road surface or when
turning the steering wheel abruptly.
Traction Control System
The traction control system automatically
helps prevent the spinning of wheels when
the vehicle is started or accelerated on
slippery road surfaces. The system oper-
ates 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
reduces 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.
WARNING
The ABS may not work properly if
tires or wheels other than those
specified in the owner’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
The ESP
®
cannot enhance the vehi-
cle’s driving stability in all situations
and does not control your vehicle’s
entire braking system. The ESP
®
can-
not prevent accidents, including
those resulting from excessive speed
in turns, or hydroplaning. Only a safe
and attentive driver can prevent acci-
dents. The capabilities of an ESP
®
-
equipped vehicle must never be used
as a substitute for careful driving.
