The sidebag inflates next to the backrest side
cushions.
Sidebags 1and 2are triggered:
R on the side on which an impact occurs
R at the start of an accident with a high rat e
of lateral vehicle deceleration or accelera-
tion, e.g. in a side impact
R independently of the use of the seat belt
R independently of the front airbags
R independently of the belt tensioners Windowbags
The purpose of the windowbags is to enhanc
e
the level of protection for the head (but not
chest or arms) of the vehicle occupants on
the side of the vehicle on which the impact
occurs.
The windowbags are integrated into the side
of the roof frame. They are located between
the front door (A-pillar) and the rear door (C -
pillar). 1

If you are driving faster than approximately
35 km/h, PRE-SAFE ®
takes the following
measures in the aforementioned situations:
R It tensions the front seat belts.
R On vehicles with the memory package*: it
adjusts the front-passenger seat to a more
favourable position.
R If the vehicle skids, it closes the sliding/
tilting sunroof* or panorama sliding/tilting
sunroof* and the side windows, leaving a
small gap.
If the hazardous situation passes without
resulting in an accident, PRE-SAFE ®
releases
the belt pretensioning. You can then readjust
the front-passenger seat and, on vehicles
with the memory package*, the sides win-
dows and the sliding/tilting sunroof* or pan-
orama sliding/tilting sunroof* .
If the seat belts are not released:
X Move the backrest or the seat back slightly
until the belt tension is reduced.
The locking mechanism releases. G
Risk of injury
Make sure that nobody can become trap -
ped as you adjust the seat. !
Make sure that there are no objects in the
footwell or behind the seats when adjustin g
the seats. You could otherwise damage the
seats and the objects . NECK-PRO head restrain
t
NECK-PRO head restraints are designed to
increase protection to the driver's and front-
passenger's head and neck. To this end, the
head restraints on the driver's and front-
passenger seats are moved forwards and
upwards in the event of a rear-end collision in
the direction of travel. This provides better
head support. G
Risk of injury
Head restraint covers prevent the NECK -
PRO head restraints from triggering cor-
rectly. Consequently, the NECK-PRO head
restraints cannot provide the intended level
of protection. Do not use head restraint
covers .
If the NECK-PRO head restraints are triggered
in an accident, you must reset the head
restraints on the driver's and front-passenger
seats (Y page 303). Head restraints that have
been triggered are tilted forwards. Children in the vehicle
If a child is travelling in your vehicle, secure
the child, preferably on a suitable seat in the
rear, using a child restraint system appropri-
ate to the size and age of the child and rec-
ommended for Mercedes-Benz vehicles. If
possible you should do this on a suitable rear
seat.
You can obtain information about the correct
child restraint system from any Mercedes-
Benz Service Centre.
i It is advisable to use Mercedes-Benz care
products to clean child restraint systems.
You can obtain information about this from
any Mercedes-Benz Service Centre. G
Risk of injury
Do not leave children unsupervised in the
vehicle, even if they are secured in a chil d
restraint system. They could be injured on
parts of the vehicle. They could be seriously
or even fatally injured by prolonged expo-
sure to extreme heat or cold.
Do not expose the child restraint system to
direct sunlight. The metallic parts of the
child restraint system could heat up and the
child could be burned by them. Safety

PASSENGER AIRBAG OFF warning lamp
5
The front-passenger seat sensor system for
child restraint systems automatically detect s
whether a special Mercedes-Benz child seat
with automatic child seat recognition has
been fitted. If this is the case, the 5
PASSENGER AIRBAG OFF warning lamp on
the centre console lights up. The front-
passenger front airbag has been disabled. G
Risk of injury
If the 5PASSENGER 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 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-passenge r
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, e.g. a
cushion, under the child restraint system.
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 protective 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 passe s
or access passes
as signals from electronic equipment can
cause interference in the automatic child
seat recognition sensor system. This can
cause the system to malfunction. It could
cause the 5PASSENGER AIRBAG OFF
warning lamp to light up even when no child
seat with automatic child seat recognition
has been fitted. The front-passenger front
airbag would not be triggered in an acci-
dent. It may also be that th e
5 PASSENGER AIRBAG OFF warning
lamp does not light up briefly when you turn
the key to position 2in the ignition lock .Safety

Child-proof locks If children are travelling in the vehicle, you can
activate the child-proof locks for the rear.
Child-proof locks for the rear doors
The child-proof locks on the rear doors enable
you to secure each door individually. You can-
not open a locked door from the inside. You
can open the door from the outside if the
vehicle is unlocked. G

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)
i In wintry road conditions, use winter tyres
(M+S tyres) and snow chains if necessary. . G
Risk of accident
The risk of an accident is significantl y
increased by driving too fast. This is partic-
ularly the case when cornering on wet and
slippery roads and when driving too clos e
to the vehicle in front.
The driving safety systems described in thi s
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 severa l
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 fee
l
a pulsing in the brake pedal.
If ABS intervenes:
X Continue to depress the brake pedal wit h
force until the braking situation is over.
For full braking application:
X Depress the brake pedal with maximum
force. Safety
