burn itself on them.
If a child opens a door, the child or other
persons could be injured as a result. The
child could get out and be injured in the
process or be injured by a passing vehicle.
G
Risk of injury
An unsecured or incorrectly positioned load
increases the risk of injury to the child in
the event of:
R an accident
R a braking manoeuvre
R a sudden change of direction
Do not carry heavy or hard objects inside
the vehicle unless they are secured. You
will find further information under "Loading
guidelines" in the index.
Child restraint systems Mercedes-Benz recommends that you only
use the child restraint systems listed on
(Y page 47). G
Risk of injury
To reduce the risk of serious or even fatal
injury to the child in the event of a sudden
change in direction, braking or an accident:
R children less than 1.50 m tall and under
twelve years of age must always be
secured in special child restraint systems
on a suitable vehicle seat. This is neces-
sary because the seat belts are not
designed for children of this size.
R Do not secure children less than 1.50 m
tall or under twelve years of age on the
front-passenger seat. Exception: the
child is secured in a vehicle with auto-
matic child seat recognition on the front-
passenger seat* and is secured in a child
restraint system with automatic child
seat recognition.
R If you secure a forward-facing child
restraint system to the front-passenger
seat, you must move the front-passenger
seat as far back as possible.
R children must never travel sitting on the
lap of another occupant. Due to the
forces occurring in the event of a sudden
change of direction, heavy braking or an
accident, it would not be possible to restrain the child. The child could be
thrown against parts of the vehicle inte-
rior and be seriously or even fatally
injured.
G
Risk of injury
The child restraint system cannot perform
its protective function if is not correctly fit-
ted to a suitable vehicle seat. The child can-
not 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 system, observe the man-
ufacturer'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
protected 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 cov-
ers with genuine Mercedes-Benz covers.
For safety reasons, you should only use
child restraint systems which have been Safety

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. 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, 5PASSENGER AIRBAG
OFF indicator lamp 1lights 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
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 sys-
tem 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 work-
shop.
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 rest on the seat cush-
ion. An incorrectly fitted child restraint sys-
tem cannot perform its intended protective
function in the event of an accident, and
could lead to injuries.
i The windowbag*, th e head/thorax airbag
and the belt tensioner for the front-
passenger seat are still active even if the
front-passenger seat front airbag has been
disabled by the automatic child seat rec-
ognition. G
Risk of injury
Do not place items of electronic equipment
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
Signals from electronic equipment can
cause interference in the automatic child
seat recognition sensor system. This could
lead to a system malfunction. This may
cause the 5PASSENGER AIRBAG OFF
warning lamp to light up without there
being a child seat with automatic child seat
recognition fitted. This means that the Safety

The vehicle will lock automatically once you
have pulled away.
You can switch off the automatic locking
function via the on-board computer
(Y page 111).
i The vehicle is locked automatically when
the ignition is switched on and the wheels
begin to turn. There is therefore a risk of
being locked out when the vehicle is being
pushed or tested on a dynamometer. Locking/unlocking the vehicle from
the inside
You can centrally lock or unlock the vehicle
from the inside. This feature may be useful if,
for example, you wish to unlock the
passenger door from the inside or lock the
vehicle before you pull away. G

Risk of poisoning
Exhaust fumes could enter the vehicle inte-

is open. This could poison you. You should
therefore make sure that the tailgate is
always closed when the engine is running.

rear when opened. Therefore, make sure
that there is sufficient clearance above and
behind the tailgate. Controls

Seats
63Seats
Points to remember
You can find information about enlarging the
luggage compartment (folding forwards/
removing the rear seats) on (Y page 150).
Depending on the vehicle's equipment, the
seats can be adjusted either manually or elec-
trically. G
Risk of injury
The seats can be adjusted when the key is
removed and the door is open. For this rea-
son, children should never be left unsuper-
vised in the vehicle. They could become
trapped when adjusting a seat. G
Risk of accident
Only adjust the driver's seat when the vehi-
cle is stationary. You will otherwise be dis-
tracted from the road and traffic conditions
and you could lose control of the vehicle as
a result of the seat moving. This could
cause an accident. G
Risk of injury
Make sure that nobody can become trap-
ped when you adjust the seat. Observe the notes concerning the airbag
system.
Secure children as recommended; see
"Children in the vehicle" section.
! When you move the seats, make sure that
there are no objects in the footwell or
behind the seats. Otherwise, you could
damage the seats and the objects.
i The front seats are fitted with active head
restraints (Y page 42). For this reason, it is
not possible to remove the head restraints
from the front seats.
The rear-compartment head restraints can
be removed (Y page 66).
