94 Safety and SecurityDriving safety systemsBraking
At the instant one of the wheels is about to
lock up, a slight pulsation can be felt in the
brake pedal, indicating that the ABS is in
the regulating mode.
Keep firm and steady pressure on the
brake pedal while experiencing the pul-
sation.
Continuous, steady brake pedal pressure
yields the advantages provided by the ABS,
namely braking power and ability to steer
the vehicle.
The pulsating brake pedal can be an
indication of hazardous road conditions
and functions as a reminder to take extra
care while driving.Emergency brake maneuver

Keep continuous full pressure on the
brake pedal.
Off-road – ABS
With the off-road driving program switched
on (page 248), the ABS designed for
off-road use is automatically activated.
When applying the brakes at speeds below
approximately 18 mph (30 km/h), the
front wheels are locked cyclically to short-
en the braking distance (dig-in effect). This
affects steering the vehicle.For more information, see “Practical hints”
(
page 381).
iWith the ABS malfunctioning, the BAS,
the ESP
®, and the 4-ETS are also
switched off.
The basic driving and braking functions
are still available.
Warning!
G
The ABS cannot prevent the natural laws of
physics from acting on the vehicle, nor can
it increase braking or steering efficiency be-
yond that afforded by the condition of the
vehicle brakes and tires or the traction
afforded. The ABS cannot prevent acci-
dents, including those resulting from exces-
sive speed in turns, following another
vehicle too closely, or hydroplaning. Only a
safe, attentive, and skillful driver can pre-
vent accidents. The capabilities of an ABS
equipped vehicle must never be exploited in
a reckless or dangerous manner which
could jeopardize the user’s safety or the
safety of others.

95 Safety and Security
Driving safety systems
BAS
The Brake Assist System (BAS) operates in
emergency situations. If you apply the
brakes very quickly, the BAS automatically
provides full brake boost, thereby poten-
tially reducing braking distance. Apply con-
tinuous full braking pressure until the
emergency braking situation is over. The
ABS will prevent the wheels from locking.
When you release the brake pedal, the
brakes function again as normal. The BAS
is then deactivated.
ESP
®
The Electronic Stability Program (ESP)
® is
operational as soon as the engine is run-
ning. It monitors the vehicle’s traction
(force of adhesive friction between the
tires and the road surface) and handling.
The ESP
® recognizes when a wheel is
spinning or if the vehicle starts to skid. By
applying brakes to the appropriate wheel
and by limiting engine output, the ESP
®
works to stabilize the vehicle. The ESP® is
especially useful while driving off and on
wet or slippery road surfaces. The ESP®
also helps stabilize the vehicle during
braking maneuvers.
The ESP
® warning lampv in the instru-
ment cluster flashes when the ESP
® is en-
gaged.
The ESP
® warning lampv in the instru-
ment cluster come on when you switch on
the ignition. It goes out when the engine is
running.
Warning!
G
If the BAS is malfunctioning, the brake sys-
tem is still functioning, but without the addi-
tional brake boost available that BAS would
normally provide in an emergency braking
maneuver. Therefore, the braking distance
may increase.
Warning!
G
The BAS cannot prevent the natural laws of
physics from acting on the vehicle, nor can
it increase braking efficiency beyond that
afforded by the condition of the vehicle
brakes and tires or the traction afforded.
The BAS cannot prevent accidents, includ-
ing those resulting from excessive speed in
turns, following another vehicle too closely,
or hydroplaning. Only a safe, attentive, and
skillful driver can prevent accidents. The
capabilities of a BAS equipped vehicle must
never be exploited in a reckless or danger-
ous manner which could jeopardize the
user’s safety or the safety of others.

Anti-theft systems
Arming the alarm system
The alarm system is armed after you have
locked the vehicle with the SmartKey or
SmartKey with KEYLESS-GO*.
The alarm system indicator lamp is located
to the lower left of the hazard warning
flasher.
1Alarm system indicator lamp

Make sure all doors and the tailgate are
closed.

Lock the vehicle (
page 60).
The turn signal lamps flash three times
to indicate that the alarm system is
activated.
Indicator lamp1 flashes permanently
to indicate that the alarm system is
armed.Disarming the alarm system

Unlock the vehicle (
page 32).
The turn signal lamps flash once to
indicate that the alarm system is
disarmed. Indicator lamp1 goes out.
iIf the turn signal lamps do not flash
three times, one of the following ele-
ments may not be properly closed:

a door


the tailgate
Close the respective element and lock
the vehicle again.
iThe alarm system will rearm automati-
cally again after approximately
40 seconds if one of the doors or the
tailgate is not opened.

102 Safety and SecurityAnti-theft systemsCanceling the alarm
To cancel the alarm:
With the SmartKey
Insert the SmartKey in the starter
switch.
or

Press theŒ or ‹button on the
SmartKey.
With KEYLESS-GO*

Grasp an outside door handle.
The SmartKey with KEYLESS-GO must
be within 3 ft (1 m) away from the
respective door.
or

Press the KEYLESS-GO start/stop
button.
The SmartKey with KEYLESS-GO must
be inside the vehicle.
Tow-away alarm
Once the tow-away alarm is armed, a visual
and audible alarm will be triggered when
someone attempts to raise the vehicle.Arming the tow-away alarm

Make sure all doors and the tailgate are
closed.

Lock your vehicle.
The tow-away alarm is automatically
armed after about ten seconds.
Disarming the tow-away alarm

Unlock your vehicle.
iThe tow-away protection alarm is trig-
gered, for example, if the vehicle is
lifted on one side.
If the alarm stays on for more than
30 seconds, a call to the Response
Center is initiated automatically by the
Tele Aid* system (
page 280), provid-
ed that the Tele Aid service was sub-
scribed to and properly activated, and
that necessary cellular service and GPS
coverage are available.
iWhen you unlock your vehicle, the
tow-away protection disarms automati-
cally.
The tow-away alarm remains disarmed
until you lock your vehicle again.

Switching off the tow-away alarm
To prevent triggering the tow-away alarm
feature, switch off the tow-away alarm be-
fore towing the vehicle, or when parking on
a surface subject to movement, such as a
ferry or auto train.
If the tow-away alarm is set to default en-
abled (On) in the control system and you
wish to retain the default setting, you can
switch off the tow-away alarm temporarily
on a one-time basis as follows:

Switch off the ignition (
page 34).
With the tow-away alarm set to default
enabled (On) in the control system, the
following message appears in the
multifunction display.

If you now wish to deactivate the
tow-away alarm on a one-time basis,
pressæ orç button on the
multifunction steering wheel.
The tow-away alarm is switched off.
The following message appears in the
multifunction display.

Exit vehicle and lock the vehicle
(page 60).
The alarm system is armed indepen-
dently of whether the tow-away alarm
is switched on or off.
iThe tow-away alarm feature can be set
to default enabled (On) or disabled (Off)
using the control system (
page 176).
iThe tow-away alarm is switched off on
a one-time basis only. It will be armed
automatically the next time you lock
the vehicle.
If you have disabled the tow-away
alarm feature in the control system
(page 176), you can also switch on
the tow-away alarm on a one-time basis
as described above.
