WARNING
Flammable material such as leaves, grass or
twigs may ignite if they come into contact with hot parts of the exhaust system. There is a risk of fire.
When driving off road or on unpaved roads,
check the vehicle's underside regularly. In
particular, remove parts of plants or other
flammable materials which have become
trapped. In the case of damage, contact a
qualified specialist workshop. G
WARNING
Modifications to electronic components, their software as well as wiring could effect their
function and/or the operation of other net-
worked components. This could in particular
also be the case for systems relevant to
safety. They might not function properly any
more and/or jeopardise the operational
safety of the vehicle. There is an increased
risk of an accident and injury.
Do not attempt to modify the wiring as well as
electronic components or their software.
Always have work on electrical and electronic components carried out at a qualified special-
ist workshop.
If you make any changes to the vehicle elec-
tronics, the general operating permit is ren-
dered invalid.
! There is a risk of damage to the vehicle if:
R the vehicle becomes stuck, e.g. on a high
kerb or an unpaved road
R you drive too fast over an obstacle, e.g. a
kerb or a pothole in the road
R a heavy object strikes the underbody or
parts of the chassis
In situations like this, the body, the under-
body, chassis parts, wheels or tyres could
be damaged without the damage being visi-
ble. Components damaged in this way can
unexpectedly fail or, in the case of an acci-
dent, no longer withstand the strain they
are designed for. If the underbody panelling is damaged,
combustible materials such as leaves,
grass or twigs can gather between the
underbody and the underbody panelling. If
these materials come in contact with hot
parts of the exhaust system, they can catch
fire.
In such situations, have the vehicle
checked and repaired immediately at a
qualified specialist workshop. If, upon con-
tinuing your journey, you notice that driving
safety is impaired, pull over and stop the
vehicle immediately, paying attention to
road and traffic conditions. In such cases,
visit a qualified specialist workshop. Declarations of conformity
Wireless vehicle components The following information applies to all com-
ponents of the vehicle and the information
systems and communication devices integra-
ted into the vehicle which receive and/or
transmit radio waves:
The components of this vehicle that receive
and/or transmit radio waves are compliant
with the basic requirements and all other rel-
evant conditions of Directive 1999/5/EC.
You can obtain further information from any
Mercedes-Benz Service Centre.
Electromagnetic compatibility The electromagnetic compatibility of the vehi-
cle components has been checked and certi- fied according to the currently valid version of Regulation ECE-R 10. Diagnostics connection
The diagnostics connection is only intended
for the connection of diagnostic equipment at a qualified specialist workshop. Introduction
25 Z

Do not keep the key:
R
with electronic devices, e.g. a mobile
phone or another key
R with metallic objects, e.g. coins or metal
film
R inside metallic objects, e.g. a metal case
This can affect the key's functionality. Key functions
:
& To lock the vehicle
; F To unlock the boot lid/tailgate
= % To unlock the vehicle
X To unlock centrally: press the%but-
ton.
If you do not open the vehicle within
approximately 40 seconds of unlocking:
R the vehicle is locked again
R the anti-theft system is primed again
X To lock centrally: press the&button.
The key centrally locks/unlocks: R the doors
R the boot lid/tailgate
R the fuel filler flap
When unlocking, the turn signals flash once.
When locking, they flash three times.
You can also set an audible signal to confirm that the vehicle has been locked. The audible
signal can be activated and deactivated using the on-board computer (Y page 255).When it is dark, the surround lighting also
comes on if it is activated in the on-board
computer (Y
page 254). KEYLESS-GO
General notes Bear in mind that the engine can be started by
any of the vehicle occupants if there is a KEY- LESS-GO key in the vehicle.
Locking and unlocking centrally You can start, lock or unlock the vehicle using
KEYLESS-GO. To do this, you only need carry the key with you. You can combine the KEY-
LESS-GO functions with the functions of a
conventional key. Unlock the vehicle by using
KEYLESS-GO, for instance, and lock it using
the & button on the key.
When locking or unlocking with KEYLESS-GO,
the distance between the key and the corre-
sponding door handle must not be greater
than 1 m.
A check which periodically establishes a radio
connection between the vehicle and the key
determines whether a valid key is in the vehi- cle. This occurs, for example:
R when the external door handles are
touched
R when starting the engine
R while the vehicle is in motion Key

Important safety notes
United Kingdom only: G
WARNING
When the double locks are activated, the
doors can no longer be opened from the
inside. People in the vehicle can no longer get out, e.g. in hazardous situations. There is a
risk of injury.
Therefore, do not leave any people unsuper-
vised in the vehicle, particularly children, eld-
erly people or people in need of special assis-
tance. Do not activate the double lock when
people are in the vehicle.
If the vehicle has been locked from the out-
side, the double-lock function is activated as
standard. It is then not possible to open the
doors from inside the vehicle. You can deac-
tivate the double-lock function by deactivat-
ing the interior motion sensor (Y page 79).
The doors can then be opened from the inside after the vehicle has been locked from the
outside. The anti-theft alarm system is trig- gered if the door is opened from the inside.
Switch off the alarm (Y
page 78).
All countries: G
WARNING
If children are left unsupervised in the vehicle, they could:
R open doors, thereby endangering other per-
sons or road users
R get out and be struck by oncoming traffic
R operate vehicle equipment and become
trapped, for example
In addition, the children could also set the
vehicle in motion, for example, if they:
R release the parking brake
R shift the automatic transmission out of park
position P or shift manual transmission into
neutral
R start the engine
There is a risk of an accident and injury.
When leaving the vehicle, always take the key with you and lock the vehicle. Never leave
children and animals unattended in the vehi-
cle. Keep the keys out of the reach of children. 88

Switching the auxiliary heating/venti-
lation on/off using the remote control General notes
Your vehicle comes with one remote control.
You may use two additional remote controls
for your vehicle. For more information, please
contact a qualified specialist workshop.
Store the remote control for the auxiliary
heating so that the auxiliary heating cannot
be switched on unintentionally. In particular,
ensure that the remote control for the auxili-
ary heating is kept out of the reach of chil-
dren. The remote control has a maximum range of
approximately 300 metres. This range is
reduced by:
R sources of radio interference
R solid objects between the remote control
and the vehicle
R the remote control being in an unfavoura-
ble position in relation to the vehicle
R transmitting from an enclosed space
i The optimum range can be achieved if you
hold the remote control vertically, pointing
upwards when you press one of the but-
tons.
i A battery symbol appears in the display
when the battery in the remote control is
low. Replace the remote control battery
(Y page 152).
