Switching the auxiliary heating/venti-
lation on/off using the remote control Your vehicle comes with one remote control.
You may use two additional remote controls
for your vehicle. For further information, con-
sult a qualified specialist workshop, e.g. a
Mercedes-Benz Service Centre. The remote control has a maximum range of
approximately 300 metres. This range may be
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 batteries in the remote control
are low. Replace the remote control bat-
teries (Y page 312).

To obtain an accurate display of your com-
pass bearing, the correct geographical zone
must be set. If necessary, the compass must
also be calibrated (Y page 213).

Problem Possible cause/consequence Suggested solutions
You cannot lock or unlock the
vehicle using the KEYLESS GO
key. The KEYLESS GO key batteries
are discharged or nearly dis-
charged. X
Lock or unlock the vehicle using the remote control function of the
key. To do this, point the tip of the key at the driver's door handle
from close range and try to unlock or lock the vehicle again.
If this does not work:
X Unlock the vehicle using the emergency key element
(Y page 308).
X Check the KEYLESS GO key batteries (Y page 311) and replace
them if necessary (Y page 311). There is a fault with KEYLESS GO. X
Lock or unlock the vehicle using the remote control function of the
key. To do this, point the tip of the key at the driver's door handle
from close range and try to open the vehicle again.
X Have the KEYLESS GO key checked at a qualified specialist work-
shop. There is interference from a pow-
erful source of radio waves. X
Unlock the vehicle using the emergency key element

Notes on changing bulbs
Bulbs and lamps are an important aspect of
vehicle safety. You must therefore make sure
that all bulbs function correctly at all times. G
Risk of injury
Bulbs and lamps can be very hot. You
should therefore allow them to cool down
before you change them. Otherwise, you
could be burned if you touch them.
Keep bulbs out of the reach of children.
Otherwise, they could damage them, for
example, and injure themselves.
Never use a bulb which has been dropped.
Such a bulb may explode and injure you.
H7 bulbs are pressurised and could explode
when you change them, particularly if they
are very hot. You should therefore wear eye
protection and gloves when you are chang-
ing them. G
Risk of injury
Xenon bulbs carry a high voltage. You could
get an electric shock and be seriously or
even fatally injured if you touch the electric
contacts on xenon bulbs. Therefore, never
remove the cover from xenon bulbs. Practical advice
