sudden change in direction. The child
restraint system could be thrown about, strik-ing vehicle occupants. There is an increased
risk of injury, possibly even fatal.
Always install child restraint systems prop-
erly, even if they are not being used. Make
sure that you observe the child restraint sys-
tem manufacturer's installation instructions.
You will find further information on stowing
objects, luggage or loads under "Loading
guidelines" ( Ypage 192).
GWARNING
Child restraint systems or their securing sys-
tems which have been damaged or subjected
to a load in an accident can no longer protect
as intended. The child cannot then be
restrained in the event of an accident, heavy
braking or sudden changes of direction. There is an increased risk of injury, possibly evenfatal.
Replace child restraint systems which have
been damaged or subjected to a load in an
accident as soon as possible. Have the secur-
ing systems on the child restraint system
checked at a qualified specialist workshop,
before you install a child restraint system
again.
The securing systems of child restraint sys-
tems are: R the seat belt system
R the LATCH-type (ISOFIX) securing rings
R the Top Tether anchorages
iIf it is absolutely necessary to carry a child
on the front-passenger seat, be sure to
observe the information on "Child restraint
systems on the front-passenger seat"( Y page 60). There you will also find infor-
mation on deactivating the front-passenger
front air bag. All child restraint systems must meet the fol-
lowing standards:
R U.S. Federal Motor Vehicle Safety Stand-
ards 213 and 225
R Canadian Motor Vehicle Safety Standards
213 and 210.2
Confirmation that the child restraint system
corresponds to the standards can be found
on an instruction label on the child restraint
system. This confirmation can also be found
in the installation instructions that are inclu-
ded with the child restraint system.
Observe the warning labels in the vehicle inte-
rior and on the child restraint system.
LATCH-type (ISOFIX) child seat secur-
ing system
GWARNING
LATCH-type (ISOFIX) child restraint systems
do not offer sufficient protective effect for
children whose weight is greater than 48 lbs
(22 kg) who are secured using the safety belt integrated in the child restraint system. In the
event of an accident, a child might not be
restrained correctly. This poses an increased
risk of injury or even fatal injury.
If the child weighs more than 48 lbs (22 kg),
only use LATCH-type (ISOFIX) child restraint
systems with which the child is also secured
with the vehicle seat belt. Also secure the
child restraint system with the Top Tether
belt, if available.
Always comply with the manufacturer's
installation and operating instructions for the child restraint system used.
Before every trip, make sure that the LATCH- type (ISOFIX) child restraint system is
engaged correctly in both LATCH-type (ISO-
FIX) securing rings
!When installing the child restraint system,
make sure that the seat belt for the middle seat does not get trapped. The seat belt
could otherwise be damaged.

BabySmart™ air bag deactivation sys-
tem
The BabySmart™ air bag deactivation sys-
tem's sensor system in the front-passenger
seat detects whether a special Mercedes-
Benz child restraint system with a trans-
ponder for the BabySmart™ air bag deactiva-
tion system has been installed. In this case,
the PASSENGER AIR BAG OFF indicator lamp lights up and remains lit. The front-passengerfront air bag is deactivated.
When the SmartKey is removed from the igni-
tion lock or is in position 0, the PASSENGER
AIR BAG OFF indicator lamp is not lit.
iIf the front-passenger front air bag is
deactivated by the BabySmart™ air bag
deactivation system, the following remain
enabled on the front-passenger side:
R the side impact air bag
R the pelvis air bag
R the window curtain air bag
R the Emergency Tensioning Device
GWARNING
If you secure a child in a child restraint system
on the front-passenger seat and the
PASSENGER AIR BAG OFF indicator lamp is
off, the front-passenger front air bag can
deploy in the event of an accident. The child
could be struck by the air bag. This poses an
increased risk of injury or even fatal injury.
Make sure that the front-passenger front air
bag has been disabled. The PASSENGER AIR
BAG OFF indicator lamp must be lit.
GWARNING
If the PASSENGER AIR BAG OFF indicator
lamp is lit, the front-passenger front air bag isdeactivated. It will not be deployed in the
event of an accident and cannot perform its
intended protective function. A person in the
front-passenger seat could then, for example, come into contact with the vehicle's interior,
especially if the person is sitting too close to
the dashboard. This poses an increased risk of injury or even fatal injury.
In this case the front-passenger seat may notbe used. You may only transport a child on the
front-passenger seat if they are seated in a
suitable rearward or forward-facing child
restraint system. Always observe the child
restraint system manufacturer's installation
instructions.
GWARNING
If you secure a child in a forward-facing child
restraint system on the front-passenger seat
and you position the front-passenger seat too close to the dashboard, in the event of an
accident, the child could:
R come into contact with the vehicle's inte-
rior if the PASSENGER AIR BAG OFF indi-
cator lamp is lit, for example
R be struck by the air bag if the PASSENGER
AIR BAG OFF indicator lamp is off
This poses an increased risk of injury or even fatal injury.
Move the front-passenger seat as far back as
possible. Always make sure that the shoulder belt strap is correctly routed from the vehicle
belt sash guide to the shoulder belt guide on
the child restraint system. The shoulder belt
strap must be routed forwards and down-
wards from the belt sash guide. If necessary,

Driving safety systems
Overview of driving safety systems
In this section, you will find information about the following driving safety systems:
R ABS ( Anti-lock Braking System)
R BAS ( Brake Assist System)
R Adaptive brake lights
R ESP ®
(E lectronic Stability Program)
R EBD ( Electronic Brake force Distribution)
R ADAPTIVE BRAKE
R Trailer stabilization
Important safety notes
GWARNING
The ABS, the BAS, and the ESP ®
switch off
when the differential locks are switched on.
When the ABS, the BAS, and the ESP ®
are
switched off
R wheels may lock during hard braking
R steering capabilities are reduced
R braking distance is increased
R vehicle stability in standard driving maneu-
vers is increased
Make sure the differential locks are switched on at all times except when driving off-road for
example. Switch on the differential locks
immediately when returning from off-roaddriving.
If you fail to adapt your driving style or if you
are inattentive, the driving safety systems can neither reduce the risk of an accident nor
override the laws of physics. Driving safety
systems are merely aids designed to assist
driving. You are responsible for the distance
to the vehicle in front, for vehicle speed and
for braking in good time. Always adapt your
driving style to suit the prevailing road and
weather conditions and maintain a safe dis-
tance from the vehicle in front. Drive care-fully.
iPlease note that the driving safety sys-
tems described only work as effectively as
possible if there is adequate contact
between the tires and the road surface. Pay particular attention to the information
regarding tires, recommended minimum
tire tread depths etc. in the "Wheels and
tires" section ( Ypage 230).
In wintry driving conditions, always use
winter tires (M+S tires) and if necessary,
snow chains. Only in this way will the driv-
ing safety systems described in this section work as effectively as possible.
64Driving safety systems
Safety
ABS (Anti-lock Braking System)
Important safety notes
iObserve the "Important safety notes" sec-
tion ( Ypage 64).
GWARNING
If the ABS malfunctions, other driving systems
such as the BAS or the ESP ®
are also switched
off. Observe indicator and warning lamps that may come on as well as messages in the mul-
tifunction display that may appear.
If the ABS malfunctions, the wheels may lock
during hard braking, reducing the steering
capability and extending the braking distance.
GWARNING
If ABS is faulty, the wheels could lock when
braking. The steerability and braking charac-
teristics may be severely impaired. Addition-
ally, further driving safety systems are deac-
tivated. There is an increased danger of skid- ding and accidents.
Drive on carefully. Have ABS checked imme-
diately at a qualified specialist workshop.
ABS regulates brake pressure in such a way
that the wheels do not lock when you brake.
This allows you to continue steering the vehi- cle when braking.
Provided that the differential locks are not
active, ABS works from a speed of about
5 mph (8 km/h) upwards, regardless of road-surface conditions. ABS works on slippery
surfaces, even if you only brake gently.
The yellow !ABS warning lamp in the
instrument cluster lights up when the ignition
is switched on. It goes out when the engine is running.
Braking
If ABS intervenes when braking, you will feel apulsing in the brake pedal. X
If ABS intervenes: continue to depress the
brake pedal vigorously until the braking sit-
uation is over.
X To make a full brake application:
depress the brake pedal with full force.
The pulsating brake pedal can be an indica-
tion of hazardous road conditions, and func-
tions as a reminder to take extra care while
driving.
Off-road ABS
If the LOW RANGE shift range is selected by
the transfer case, ( Ypage 132), an ABS sys-
tem specifically suited to off-road terrain is
automatically activated.
At speeds below 37 mph (60 km/h), the front wheels lock cyclically during braking. The dig-
ging-in effect achieved in the process reduces
the stopping distance on off-road terrain. This limits steering capability.
BAS (Brake Assist System)
iObserve the "Important safety notes" sec-
tion ( Ypage 64).
GWARNING
If BAS is malfunctioning, the braking distance
in an emergency braking situation is
increased. There is a risk of an accident.
In an emergency braking situation, depress
the brake pedal with full force. ABS prevents
the wheels from locking.
BAS operates in emergency braking situa-
tions. If you depress the brake pedal quickly,
BAS automatically boosts the braking force,
thus shortening the stopping distance.
X Keep the brake pedal firmly depressed until
the emergency braking situation is over.
ABS prevents the wheels from locking.
The brakes will function as usual once you
release the brake pedal. BAS is deactivated.
Driving safety systems65
Safety
Z
Adaptive brake lights
If you brake sharply from a speed of more
than 30 mph (50 km/h) or if braking is assis-ted by BAS, the brake lamps flash rapidly. In
this way, traffic traveling behind you is
warned in an even more noticeable manner.
If you brake sharply from a speed of more
than 45 mph (70 km/h)to a standstill, the
hazard warning lamps are activated automat-
ically. If the brakes are applied again, the
brake lamps light up continuously. The hazard
warning lamps are deactivated automatically if you drive faster than 6 mph (10 km/h). You
can also switch off the hazard warning lamps using the hazard warning button( Y page 90).
ESP®(Electronic Stability Program)
Important safety notes
iObserve the "Important safety notes" sec-
tion ( Ypage 64).
GWARNING
If ESP ®
is malfunctioning, ESP ®
is unable to
stabilize the vehicle. Additionally, further driv- ing safety systems are deactivated. This
increases the risk of skidding and an accident.
Drive on carefully. Have ESP ®
checked at a
qualified specialist workshop.
!Only operate the vehicle for a maximum of
ten seconds on a brake test dynamometer.
Switch off the ignition.
Application of the brakes by ESP ®
may oth-
erwise destroy the brake system.
!A function or performance test should
only be carried out on a two-axle dyna-
mometer. Before you operate the vehicle
on such a dynamometer, please consult a
qualified workshop. You could otherwise
damage the drive train or the brake system. ESP
®
monitors the driving stability and the
traction. Traction is the power transmission
between the tires and the road surface. ESP ®
is deactivated if the åwarning lamp
in the instrument cluster lights up continu-
ously when the engine is running.
If the ÷ warning lamp and the åwarn-
ing lamp are lit continuously, ESP ®
is not
available due to a malfunction.
Observe the information on warning lamps ( Y page 165) and display messages which
may be displayed in the instrument cluster( Y page 148).
If ESP ®
detects that the vehicle is deviating
from the direction desired by the driver, one
or more wheels are braked to stabilize the
vehicle. If necessary, the engine output is also modified to keep the vehicle on the desired
course within physical limits. ESP ®
assists
the driver when pulling away on wet or slip-
pery roads. ESP ®
can also stabilize the vehi-
cle during braking.
If ESP ®
intervenes, the ÷warning lamp
flashes in the instrument cluster.
If ESP ®
intervenes:
X Do not deactivate ESP ®
under any circum-
stances.
X Only depress the accelerator pedal as far as
necessary when pulling away.
X Adapt your driving style to suit the prevail-
ing road and weather conditions.
iOnly use wheels with the recommended
tire sizes. Only then will ESP ®
function
properly.
iIf differential locks are switched on, ABS,
BAS and ESP ®
switch off automatically.
4ETS (Electronic Traction System)
iObserve the "Important safety notes" sec-
tion ( Ypage 64).
Traction control remains active, even if you
deactivate ESP ®
.
66Driving safety systems
Safety
XIf appropriate for the driving conditions,
engage the LOW RANGE off-road gear
( Y page 132).
Traction control is part of ESP ®
.
Traction control brakes the drive wheels indi-
vidually if they spin. This enables you to pull
away and accelerate on slippery surfaces, for
example if the road surface is slippery on one
side. In addition, more drive torque is trans-
ferred to the wheel or wheels with traction.
Traction control remains active, even if you
deactivate ESP ®
.
Traction control is no longer active above a
speed of approximately 37 mph (60 km/h).
Traction control brakes the drive wheels indi-
vidually if they spin. This enables you to pull
away and accelerate on slippery surfaces, for
example if the road surface is slippery on one
side. In addition, more drive torque is trans-
ferred to the wheel or wheels with traction.
Deactivating/activating ESP®
iObserve the "Important safety notes" sec-
tion ( Ypage 64).
GWARNING
If you deactivate ESP ®
, ESP ®
no longer sta-
bilizes the vehicle. There is an increased risk
of skidding and an accident.
Only deactivate ESP ®
in the situations descri-
bed in the following.
!Avoid spinning the driven wheels for an
extended period with ESP ®
deactivated.
You could otherwise damage the drivetrain.
X To deactivate: press button:until the
å warning lamp lights up in the instru-
ment cluster.
X To activate: press button :until the å
warning lamp goes out in the instrument cluster.
ESP ®
is activated automatically when the
engine is started.
iVehicles with the ECO start/stop func-
tion: the ECO start/stop function automat-
ically switches the engine off when the
vehicle comes to a stop. The engine starts
automatically when the driver wants to pull
away again. ESP ®
remains in its previously
selected status. For example, if ESP ®
was
deactivated before the engine was
switched off, ESP ®
remains deactivated
when the engine is switched on again.
It may be best to deactivate ESP ®
in the fol-
lowing situations:
R when using snow chains
R in deep snow
R on sand or gravel
If you deactivate ESP ®
:
R ESP ®
no longer improves driving stability.
R the engine's torque is no longer limited and
the drive wheels can spin. The spinning of
the wheels results in a cutting action, which
provides better grip.
R traction control is still activated.
R ESP ®
still provides support when you
brake.
R and are driving at above 37 mph (60 km/h)
(on AMG vehicles above 62 mph
(100 km/h)), ESP ®
still intervenes when
one wheel reaches its grip limit even
though it is deactivated.
iIf ESP ®
is deactivated and one or more
wheels start to spin, the ÷warning lamp
in the instrument cluster flashes. In such
situations, ESP ®
will not stabilize the vehi-
cle.
Driving safety systems67
Safety
Z
iIf ESP®
is deactivated, it is reactivated
automatically if you are driving at above
37 mph (60 km/h) (on AMG vehicles above
62 mph (100 km/h)) or you exceed a cer-
tain lateral acceleration.
Trailer stabilization
GWARNING
If road and weather conditions are poor,
trailer stabilization will not be able to prevent the vehicle/trailer combination from swerv-
ing. Trailers with a high center of gravity can
tip over before ESP ®
can detect this. There is
a risk of an accident.
Always adapt your driving style to the prevail- ing road and weather conditions.
Trailer stabilization does not work if ESP ®
is
deactivated because of a malfunction.
If your vehicle with trailer (vehicle/trailer
combination) begins to lurch, you can only
stabilize the vehicle/trailer combination by
depressing the brake firmly.
In this situation, ESP ®
assists you and can
detect if the vehicle/trailer combination
begins to lurch. ESP ®
slows the vehicle down
by braking and limiting the engine output until the vehicle/trailer combination has stabi- lized.
Trailer stabilization is active above speeds of
about 37 mph (60 km/h).
EBD (electronic brake force distribu- tion)
iObserve the "Important safety notes" sec-
tion ( Ypage 64).
GWARNING
If EBD is malfunctioning, the rear wheels can
lock, e.g. under full braking. This increases the
risk of skidding and an accident.
You should therefore adapt your driving style
to the different handling characteristics. Have
the brake system checked at a qualified spe-
cialist workshop.
Observe information regarding indicator and
warning lamps ( Ypage 163) as well as dis-
play messages ( Ypage 148).
EBD monitors and controls the brake pres-
sure on the rear wheels to improve driving
stability while braking.
ADAPTIVE BRAKE
ADAPTIVE BRAKE provides increased braking
safety. In addition to the braking function,
ADAPTIVE BRAKE also has the HOLD function
( Y page 126) and hill start assist
( Y page 105).
