Electronic stability program
(ESP
®
) (if equipped)
ESP
®
is a registered trademark of Daimler
AG.
The Electronic Stability Program (ESP
®
)
helps to control the vehicle during corner-
ing if front wheels or rear wheels skid. It
also assists you in maintaining traction
while accelerating on loose or slippery
road surfaces. It does this by regulating
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 sys-
tems:
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 clunking sound when you
start the engine or after the vehicle begins
to move. This means that the above sys-
tems are in the self-check mode. This
sound does not indicate a malfunction.
Anti-lock brake system (ABS)
ABS will help you avoid skidding by elec-
tronically controlling braking pressure. It
will also help you maintain steering control
when braking on slippery surfaces or when
braking hard. The ABS works automati-
cally, so you do not have to use any spe-
cial braking technique. Just push the brake
pedal down without pumping. The ABS will
operate whenever it senses that wheels
are locking up. You may feel the brake
pedal pulsate while the ABS is operating.
(For more information on ABS, see “Brak-
ing” in this section.)
NOTE:
• The ABS will not work if vehicle speed is
under about 9 km/h.
• If the ABS system is activated, you may
hear a clunking noise and/or feel pulsat-
ing in the brake pedal. This is normal
and indicates that the brake fluid pres-
sure is being controlled properly.
• You may hear an operation sound when
you start the engine or after the vehicle
begins to move. This means that the
above systems are in the self-check
mode. This sound does not indicate a
malfunction.
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 safe
and attentive drive can prevent acci-
dents. The capabilities of an ESP
®
-
equipped vehicle must never be used
as a substitute for careful driving.
