Index
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 visible.
Components damaged in this way can unex-
pectedly fail or, in the case of an accident, no
longer withstand the strain they are designed for.
If the underbody panelling is damaged, com-
bustible 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 spe-
cialist workshop. If, upon continuing your
journey, you notice that driving safety is
impaired, pull over and stop the vehicle imme- diately, paying attention to road and traffic
conditions. In such cases, consult a qualified
specialist workshop. Declarations of conformity
Wireless vehicle components The following information applies to all compo-
nents of the vehicle and the information sys-
tems and communication devices integrated
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 relevant
conditions of Directive 1999/5/EC. You can
obtain further information from any Mercedes-
Benz Service Centre. Electromagnetic compatibility The electromagnetic compatibility of the vehicle
components has been checked and certified
according to the currently valid version of Reg-
ulation ECE-R 10. Diagnostics connection
The diagnostics connection is only intended for the connection of diagnostic equipment at a
qualified specialist workshop. G
WARNING
If you connect equipment to a diagnostics
connection in the vehicle, it can affect the
operation of the vehicle systems. This may
affect the operating safety of the vehicle.
There is a risk of an accident.
Do not connect any equipment to a diagnos-
tics connection in the vehicle. G
WARNING
Objects in the driver's footwell may restrict
the clearance around the pedals or block a
depressed pedal. This jeopardises the oper-
ating and road safety of the vehicle. There is a risk of an accident.
Stow all objects securely in the vehicle so that
they do not get into the driver's footwell.
Always fit the floormats securely and as pre-
scribed in order to ensure that there is always sufficient room for the pedals. Do not use
loose floormats and do not place several floor-mats on top of one another.
! If the engine is switched off and equipment
on the diagnostics connection is used, the
starter battery may discharge.
Connecting equipment to the diagnostics con-
nection can lead to emissions monitoring infor-
mation being reset, for example. This may lead
to the vehicle failing to meet the requirements of
the next emissions test during the main inspec- tion. Operating safety

X
To lock centrally: press the&button.
The key centrally locks/unlocks: R the doors
R the boot lid
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 or deactivated using the on-board computer (Y page 219).
When it is dark, the surround lighting also comes
on if it is activated in the on-board computer
(Y page 218). 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 (Y page 134).
Locking and unlocking centrally You can start, lock or unlock the vehicle using
KEYLESS-GO. To do this, you need to carry the
key with you. You can combine the KEYLESS-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 vehicle. This occurs, for example:
R when the external door handles are touched
R when starting the engine
R whilst driving X
To unlock the vehicle: touch the inner sur-
face of the door handle.
X To lock the vehicle: touch sensor sur-
face :.
X Convenience closing feature: touch
recessed sensor surface ;for an extended
period.
For further information on the convenience
closing feature (Y page 86). X
To unlock the boot lid: pull the boot lid han-
dle.
The vehicle only unlocks the boot lid.
Deactivating and activating If you do not intend to use a key for an extended
period of time, you can deactivate the KEYLESS-
GO function of the key. The key will then use very
little power, thereby conserving battery power.
For the purposes of activation or deactivation,
the vehicle does not have to be nearby. Key

of the front-passenger door handle.
X To lock centrally: touch the outer sensor
surface on one of the door handles.
X To restore the factory settings: press and
hold down the %and& buttons simul-
taneously for approximately six seconds until
the battery check lamp flashes twice
(Y page 77). Emergency key element
General notes If the vehicle can no longer be locked or
unlocked with the key, use the emergency key
element.
If you use the emergency key element to unlock
and open the driver's door or the boot lid, the
anti-theft alarm system will be triggered. Switch
off the alarm (Y page 71).
If you unlock the vehicle using the emergency
key element, the fuel filler flap will not be
unlocked automatically.
X To unlock the fuel filler flap: insert the key
into the ignition lock.
Removing the emergency key element X
Push release catch :in the direction of the
arrow and, at the same time, remove emer-
gency key element ;from the key.
