does not generally constitute a health hazard.
The + warning lamp lights up.
i If the belt buckle tensioners have been
triggered on the front seats, the buckle will
be pulled down and will be almost flush with
the upper edge of the seat. The +warn-
ing lamp comes on. G
Risk of injury
The belt buckle tensioners on the front seats
only function if the belt buckles can be pulled
down without obstruction. They must not be
restricted in any way. For this reason, do not
hold the belt buckles and do not place any
objects under the belt buckles. Otherwise, the
tensioning of the belt by the buckle is restric-
ted or will not function and will not provide
any additional protection. G
Risk of injury
If the seat belt tensioners have been trig-
gered, they provide no additional protection
in the event of another accident. Therefore,
have belt tensioners which have been trig-
gered replaced at a qualified specialist work-
shop.
Comply with safety regulations when dispos-
ing of belt tensioners. Any Mercedes-Benz
Service Centre can provide details of these
regulations.
Airbags Airbag deployment slows down and restricts
the movement of the vehicle occupant.
If the airbags are deployed, you will hear a
bang and a small amount of powder may also
be released. Only in rare cases will the bang
affect your hearing. The powder that escapes
does not generally constitute a health hazard.
The + warning lamp lights up.
The SRS/AIRBAG identification indicates the
location of the airbags. G
Risk of injury
Airbags provide additional protection; they
are not, however, a substitute for seat belts.
Observe the following notes to reduce the risk
of serious or even fatal injury if an airbag is
deployed:
R all vehicle occupants ― in particular, preg-
nant women ― must wear their seat belt
correctly at all times and lean back against
the backrest, which should be positioned
as close to the vertical as possible. The
head restraint must support the back of the
head at about eye level.
R always secure children less than 1.50 m tall
or under 12 years of age in suitable child
restraint systems.
R all vehicle occupants must select a seat
position that is as far away from the airbag
as possible. The driver's seat position must
allow the vehicle to be driven safely. The
driver's chest should be as far away from
the middle of the driver's front airbag cover
as possible.
R move the front-passenger seat as far back
as possible, especially if a child is secured
in a child restraint system on the seat.
R vehicle occupants – in particular, children
– must not lean their head into the area of
the window in which the sidebag/window-
bag is deployed.
R rearward-facing child restraint systems
must not be fitted to the front-passenger
seat unless the front-passenger front air-
bag has been disabled. The front-passenger
front airbag of a vehicle fitted with auto-
matic child seat recognition* is only disa-
bled when a child restraint system with
automatic child seat recognition is fitted to
the front-passenger seat. The 4
PASSENGER AIRBAG OFF warning lamp
must be continuously lit.

it would not be possible to restrain the
child. The child could be thrown against
parts of the vehicle interior and be seriously
or even fatally injured. G
Risk of injury
The child restraint system cannot perform its
protective function if it is not correctly fitted
to a suitable vehicle seat. The child cannot be
restrained in the event of a sudden change of
direction, heavy braking or an accident. This
may lead to serious or even fatal injuries. For
this reason, when fitting a child restraint sys-
tem, observe the manufacturer's installation
instructions and the correct use of the child
restraint system.
Child restraint systems should be fitted to the
rear seats. Children are generally better pro-
tected there.
The entire base of the child restraint system
must always rest on the seat cushion. Never
place objects, e.g. a cushion, under the child
restraint system.
Only use child restraint systems with their
original covers. Only replace damaged covers
with genuine Mercedes-Benz covers.
For safety reasons, you should only use child
restraint systems which have been approved
for use in Mercedes-Benz vehicles.

Risk of injury
If the front-passenger front airbag is not dis-
abled:
R a child secured in a child restraint system
on the front-passenger seat could be seri-
ously and even fatally injured by the front-
passenger front airbag deploying. This is
especially a risk if the child is in the imme-
diate vicinity of the front-passenger front
airbag when it deploys.
R a child must never be secured on the front-
passenger seat in a rearward-facing child
restraint system. Only secure a rearward-
facing child restraint system on a suitable
rear seat.
R always move the front-passenger seat to
the rearmost position if you secure a child
in a forward-facing child restraint system
on the front-passenger seat.

the
4 PASSENGER AIRBAG OFF warning
lamp is not lit.
To alert you to this danger, a corresponding
warning sticker is located on the dashboard
and on both sides of the sun visor on the front-
passenger side.
Information about recommended child
restraint systems is available at any
Mercedes-Benz Service Centre.
Automatic child seat recognition on the
front-passenger seat
If your vehicle does not have automatic child
seat recognition on the front-passenger seat,
this is indicated by a special sticker. The
sticker is affixed to the side of the dashboard
on the front-passenger side. It is visible when
you open the front-passenger door.
The warning lamp 3
is located on the centre
console. The sensors for the automatic child seat rec-
ognition on the front-passenger seat detects
whether a special Mercedes-Benz child seat
with automatic child seat recognition has
been fitted. In such cases, 4PASSENGER
AIRBAG OFF warning lamp :lights up. The
front-passenger front airbag is disabled. G
Risk of injury
If the 4 PASSENGER AIRBAG OFF warning
lamp does not light up when the child restraint
system is fitted, the front-passenger front air- bag has not been disabled. If the front-
passenger front airbag is deployed, the child
could be seriously or even fatally injured.
Proceed as follows:
R
do not use a rearward-facing child restraint
system on the front-passenger seat.
R fit a rearward-facing child restraint system
on a suitable rear seat.
or
R only use a forward-facing child restraint
system on the front-passenger seat and
move the front-passenger seat to its rear-
most position.
R have the automatic child seat recognition
checked at a qualified specialist workshop.
To ensure that the automatic child seat rec-
ognition on the front-passenger seat func-
tions correctly, never place objects (such as
a cushion) under the child restraint system.
The entire base of the child restraint system
must always rest on the seat cushion. An
incorrectly fitted child restraint system can-
not perform its intended protective function
in the event of an accident, and could lead to
injuries.
i The windowbag, the sidebag and the belt
tensioner on the front-passenger side are
still active even if the front-passenger front
airbag is disabled by the automatic child-
seat recognition on the front-passenger
seat. G
Risk of injury
Do not place electronic devices on the front-
passenger seat, e.g.:
R laptops, when switched on
R mobile phones
R cards with transponders, e.g. ski passes or
access cards
3 Vehicles without automatic child seat recognition in the front-passenger seat: the warning lamp lights up

Overview of driving safety systems
In this section, you will find information about
the following driving safety systems:

R Distance warning function* (vehicles with
Distronic*)
i In wintry driving conditions, always use
winter tyres (M+S tyres) and if necessary,
snow chains. Only in this way will the driv-
ing safety systems described in this section
work as effectively as possible. G
Risk of accident
The risk of an accident is significantly
increased by driving too fast. This is particu-
larly the case when cornering as well as on
wet or slippery roads or when driving too close
to the vehicle in front.
The driving safety systems described in this
section can neither reduce this risk nor over-
ride the laws of physics.
For this reason, always adapt your driving
style to suit prevailing road and weather con-
ditions. Maintain sufficient distance from
other road users and objects on the road. ABS (Anti-lock Braking System)
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.
ABS works from a speed of about 8 km/h
upwards, regardless of road-surface condi-
tions. ABS works on slippery surfaces, even
when you only brake gently. G
Risk of accident
Do not depress the brake pedal several times
in quick succession (pumping). Depress the
brake firmly and evenly. Pumping the brake
pedal reduces the braking effect.
Braking If ABS intervenes when braking, you will feel
a pulsing in the brake pedal. X
If ABS intervenes: continue to depress the
brake pedal with force until the braking sit-
uation is over.
X To make a full brake application:
depress the brake pedal with full force. G
Risk of accident
If ABS is faulty, the wheels could lock when
braking. This limits the steerability of the vehi-
cle when braking and the braking distance
may increase.
If ABS is deactivated due to a malfunction,
then BAS and ESP are also deactivated. There
is an increased risk of your vehicle skidding in
certain situations.
You should always adapt your driving style to
suit prevailing road and weather conditions.
Off-road ABS An ABS system specifically suited to off-road
terrain is activated automatically if the LOW
RANGE (Y
page 114) off-road gear is selec-
ted.
At speeds below 30 km/h, the front wheels
lock cyclically under braking. The resulting
digging-in effect reduces the stopping dis-
tance on off-road terrain. This limits steering
capability. BAS (Brake Assist)
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. G
Risk of accident
If BAS has malfunctioned, the braking system
remains available with full brake boosting 50

effect. However, braking force is not auto-
matically increased in emergency braking sit-
uations and the stopping distance may
increase. Adaptive brake lamps
i Adaptive brake lamps are only available in
certain countries.
If you brake sharply from a speed of more
than 25 km/ho r if braking is assisted by BAS,
the brake lamps flash rapidly. In this way,
traffic travelling behind you is warned in an
even more noticeable manner.
If you brake sharply from a speed of more
than 70 km/h to a standstill, the hazard warn-
ing lamps are activated automatically. If the
brakes are applied again, the brake lamps
light up continuously. The hazard warning
lamps switch off automatically if you travel
faster than 10 km/h. You can also switch off
the hazard warning lamps using the hazard
warning switch button (Y page 81).ESP
®
(Electronic Stability Program)
ESP ®
monitors driving stability and traction,
i.e. power transmission between tyres and
the road surface.
If ESP ®
detects that the vehicle is deviating
from the direction desired by the driver, one
or more wheels are braked to stabilise 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 stabilise the vehi-
cle during braking.
When ESP ®
intervenes, the dwarning
lamp flashes in the instrument cluster. G
Risk of accident
If the d warning lamp in the instrument
cluster flashes, proceed as follows: R
do not deactivate ESP ®
under any circum-
stances.
R only depress the accelerator pedal as far as
necessary when pulling away.
R adapt your driving style to suit the prevail-
ing road and weather conditions.
Otherwise, the vehicle could skid.
ESP ®
cannot reduce the risk of an accident if
you drive too fast. ESP ®
cannot override the
laws of physics.
! Only operate the vehicle briefly (for a max-
imum of ten seconds) on a brake dyna-
mometer. Turn the key in the ignition lock
to position 0or 1. You could otherwise
damage the drive train or the brake system.
! A function or performance test should
only be carried out on a twin-axle dyna-
mometer. If you wish to operate the vehicle
on such a dynamometer, please consult a
Mercedes-Benz Service Centre in advance.
You could otherwise damage the drive train
or the brake system.
i Only use wheels with the recommended
tyre sizes. Only then will ESP ®
function
properly.

trailer stabilisation If your trailer begins to lurch, you can only
stabilise the vehicle/trailer combination by
depressing the brake firmly.
In this situation, ESP
®
assists you and can
detect when the trailer begins to lurch.
ESP ®
slows the vehicle down by braking and
limiting the engine output until the vehicle/
trailer combination has stabilised.
Trailer stabilisation is active above speeds of
about 65 km/h. G

R the engine's torque is no longer limited and
the drive wheels can spin. 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

ted. It intervenes with a delay if there is over-
steering or understeering, thus improving
traction. EBV (electronic brake force distribu-
tion)
EBV monitors and controls the brake pres-
sure on the rear wheels to improve driving
stability when braking. 52

Risk of accident
If EBV is malfunctioning, the brake system is
still available with full brake boosting effect.
However, the rear wheels can still lock, e.g.
under full braking. This could cause you to
lose control of your vehicle and cause an acci-
dent. You should therefore adapt your driving
style to the different handling characteristics. 4ETS (Electronic Traction System)
4ETS makes it possible to pull away or accel-
erate on a slippery surface. It brakes the
wheels individually if they start to spin.
The d warning lamp in the instrument
cluster lights up briefly when the engine is
started. This indicates that the warning lamp
is operational.
X Activate the LOW RANGE off-road gear
(Y page 114) if appropriate to driving con-
ditions.
The d warning lamp in the instrument
cluster flashes at any speed if at least one tyre
has exceeded its tyre grip limit. G
Risk of accident
If the d warning lamp in the instrument
cluster flashes, proceed as follows:
R only depress the accelerator pedal as far as
necessary when pulling away.
R accelerate less when driving.
R adapt your driving style to suit the prevail-
ing road and weather conditions.
Otherwise, the vehicle could skid.
If you drive too fast, 4ETS cannot reduce the
risk of an accident. 4ETS cannot override the
laws of physics.
! Only operate the vehicle briefly (for a max-
imum of ten seconds) on a brake dyna-
mometer. Turn the key in the ignition lock
to position 0or 1. You could otherwise
damage the drive train or the brake system. !
A function or performance test should
only be carried out on a twin-axle dyna-
mometer. If you wish to operate the vehicle
on such a dynamometer, please consult a
Mercedes-Benz Service Centre in advance.
You could otherwise damage the drive train
or the brake system.
i If the brakes are subjected to heavy loads,
4ETS switches off automatically for a brief
period so that the brakes do not heat up
further. If, for this reason, 4ETS does not
engage, the dwarning lamp in the
instrument cluster lights up. The message
ABS, ESP unavailable see Owner's
Manual also appears in the multi-function
display.
! The engine must be off when the parking
brake is being checked on the brake dyna-
mometer. Application of the brakes via
4ETS may otherwise destroy the braking
system.

(Y page 114). Distance warning function* (vehicles
with Distronic*)
This function will issue a warning at speeds of
around 30 km/h or more if:
R for a period of several seconds, the dis-
tance to the vehicle in front is too short for
the speed at which you are travelling. The
