Risk of injury
If the front-passenger front airbag is not
disabled:
R a child secured in a child restraint system
on the front-passenger seat can be seri-
ously and even fatally injured by the
front-passenger airbag deploying. This is
especially likely if the child is in the imme-
diate vicinity of the front-passenger front
airbag when it is deployed.
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 front-passenger front airbag is not dis-
abled:
R on vehicles without automatic child seat
recognition in the front-passenger seat*
R on vehicles with automatic child seat rec-
ognition on the front-passenger seat* if there is no child restraint system with
automatic child seat recognition fitted to
the front-passenger seat.
R on vehicles with automatic child seat rec-
ognition on the front-passenger seat*, if
the 5 PASSENGER AIRBAG OFF warn-
ing lamp is not lit.
To draw attention to this danger, there is an
appropriate warning sticker on the dash-
board as well as 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 dash-
board on the front-passenger side. It is visible
when you open the front-passenger door.
The warning lamp 6
is located on the centre
console.1 5 PASSENGER AIRBAG OFF warning
lamp
The front-passenger seat sensor system for
child restraint systems detects whether a
special Mercedes-Benz child seat with auto-
matic child seat recognition has been fitted.
In such cases, the 5 PASSENGER AIRBAG
OFF indicator lamp 1 lights up. The front-
passenger airbag is deactivated.
G Risk of injury
If the 5 PASSENGER AIRBAG OFF warn-
ing lamp does not light up when the child
restraint system is fitted, the front-
passenger front airbag has not been disa-
bled. If the front-passenger front airbag is
6 Vehicles without automatic child seat recognition in the front-passenger seat: the warning lamp lights up briefly when you turn the key to position 2 in the ignition
lock. However, it has no function and does not indicate that there is automatic child seat recognition on the front-passenger seat.

Occupant safety
52 inflated, 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 sys-
tem on a suitable rear seat.
or
R Only use a forward-facing child seat on
the front-passenger seat and move the
front-passenger seat to its rearmost
position.
R Have the automatic child seat recogni-
tion 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 sys-
tem. The entire base of the child restraint
system
must always be resting on the seat
cushion. An incorrectly fitted child restraint
system cannot perform its intended pro-
tective function in the event of an accident,
and could even 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. G
Risk of injury
Do not place items of electronic equipment
on the front-passenger seat, e.g.:
R laptops, if switched on
R mobile phones
R cards with transponders, e.g. ski passes
or access passes
Signals from electronic equipment can
cause interference in the automatic child
seat recognition sensor system. This can
lead to a system malfunction. This may
cause the 5 PASSENGER AIRBAG OFF
warning lamp to light up without there
being

a child seat with automatic child seat
recognition fitted. This means the front-
passenger airbag is not deployed during an
accident. It is also possible that the
5 PASSENGER AIRBAG OFF warning
lamp will not light up if you turn the key in
the ignition lock to position 2.Safety

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 lamps
R ESP ®
(
Electronic Stability Program)
R EBV (electronic brake-power distribution)
R ADAPTIVE BRAKE
i In wintry road conditions, always use win-
ter tyres (M+S tyres) and, where 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 partic-
ularly the case when cornering on wet and
slippery roads and when driving too close
to the vehicle in front.
The driving safety systems described in this
section cannot reduce this risk or override
the laws of physics.
For this reason, always adapt your driving
style to suit the prevailing road and weather
conditions. 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. Pump-
ing the brake pedal reduces the braking
effect.
Braking
If ABS intervenes when braking, you will feel
a pulsing in the brake pedal.

If ABS intervenes:
X
Continue to depress the brake pedal with
force until the braking situation is over.
For full braking application:
X Depress the brake pedal with maximum
force. G
Risk of accident
If ABS is faulty, the wheels could lock when
braking. This limits the steerability of the
vehicle when braking and the braking dis-
tance may increase.
If ABS is deactivated due to a malfunction,
then
BAS and ESP are also deactivated. The
risk of your vehicle skidding is then
increased in certain situations.
You should therefore always adapt your
driving style to suit the prevailing road and
weather conditions. 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 sys-
tem
remains available with full brake boost-
ing effect. However, braking force is not
automatically increased in emergency
braking situations and the stopping dis-
tance 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 50 km/h or 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 from a speed of more than
70 km/h and bring the vehicle to a halt, the
hazard warning lamps switch on automati-
cally once the vehicle is stationary and the
brake lamps light up constantly if you depress
the brake pedal again. The hazard warning
lamps switch off automatically if you travel
faster than 10 km/h again. Safety

To deactivate/activate ESP ®
X To deactivate: press button 1.
The v warning lamp in the instrument
cluster lights up.
G Risk of accident
If the v warning lamp in the instrument
cluster is permanently lit when the engine
is running, ESP ®
is deactivated or not avail-
able due to a malfunction. The risk of your
vehicle skidding is then increased in certain
situations.
You should always adapt your driving style
to suit the prevailing road and weather con-
ditions. X
To activate: press button 1.
The v warning lamp in the instrument
cluster goes out.
EBV (electronic brake-power distribu-
tion)
EBV monitors and controls the brake pres-
sure on the rear wheels to improve driving
stability under braking.
G 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 accident. You should there-
fore adapt your driving style to the different
handling characteristics.
ADAPTIVE BRAKE
Due to its higher level of braking safety,
ADAPTIVE BRAKE offers exceptional braking
comfort. In addition to the braking function,
ADAPTIVE BRAKE also features the conveni-
ence function HOLD (Y page 144). For fur-
ther information, see Driving tips
(Y page 206).

An audible and visual alarm is triggered if your
vehicle's angle of inclination is altered while
tow-away protection is primed. This happens
if the vehicle is jacked up on one side, for
example.
Priming tow-away protection X
Lock the vehicle using the key. On vehicles
with KEYLESS GO*, the locking button on
the door handle/boot lid can also be used.
Tow-away protection is primed after
approximately 30 seconds.
To deactivate tow-away protection When you unlock your vehicle using the key
or KEYLESS GO*, tow-away protection is
automatically deactivated.
Deactivate tow-away protection manually to
prevent a false alarm if your vehicle:

If the interior motion sensor is primed, a vis-
ual and audible alarm is triggered if move-
ment is detected in the vehicle interior while
the vehicle is locked. This occurs, for exam-
ple, if someone breaks the side windows of
your vehicle or reaches into the vehicle's inte-
rior.
Priming the interior motion sensor X
Make sure that:
R
the side windows are closed
R the sliding/tilting sunroof* is closed
R there are no objects, e.g. mascots, hang-
ing on the rear-view mirror or on the
grasp handles on the roof trim.
This will prevent false alarms.
