Risk of injury
Very hot or very cold air can flow from the
air vents. This could cause burns or frost-
bite to bare skin in the immediate vicinity
of the vents. Keep bare skin away from
these air outlets. If necessary, direct the
airflow away to a different area of the vehi-
cle interior.
Please observe the following notes to ensure
that the air can flow freely through the air
vents:
R keep the air inlet between the windscreen
and the bonnet free of deposits, such as ice
and snow, to guarantee the supply of fresh
air into the vehicle interior.
R never cover the vents or air inlet and outlet
grilles in the vehicle interior.
i Position the sliders for the centre air
vents in the central position to provide vir-
tually draught-free ventilation. Cont

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).

Risk of injury
Children could injure themselves if they
operate the sliding/tilting sunroof.
Never leave children unsupervised in the
vehicle. Always take the KEYLESS–GO
key* with you when leaving the vehicle,
even if you are only leaving it for a short
time. G
Risk of injury
Make sure that nobody can become trap-
ped when you are opening and closing the
sliding/tilting sunroof. If there is a risk of
entrapment, release the switch and push it
briefly in any direction to stop the sliding/
tilting sunroof. G
Risk of injury
The glass in the sliding/tilting sunroof
could break in an accident. If you are not
wearing a seat belt, there is a risk that you
could be thrown through the opening in the
event of the vehicle overturning. Therefore,
always wear a seat belt to reduce the risk
of injuries. !
Only open the sliding/tilting sunroof if it
is free of snow and ice. Otherwise, mal-
functions may occur.
Do not allow anything to protrude from the
sliding/tilting sunroof. The seals could oth-
erwise be damaged.
i Resonance noises can occur in addition
to the usual airflow noises when the slid-
ing/tilting sunroof is open. They are caused
by minor pressure fluctuations in the vehi-
cle interior.
Change the position of the sliding/tilting
sunroof or open a side window slightly to
reduce or eliminate these noises.
i It is also possible to open and close the
sliding/tilting sunroof from the outside
using the "Summer opening" (Y page 101)
and "Convenience closing" (Y page 102)
features respectively.
When PRE-SAFE ®
* has been activated, the
sliding/tilting sunroof closes automatically in
the event of danger, leaving a small gap open. Controls

X Slide the lower end of the mobile phone
into connector contact 2in mobile phone
bracket 3.
X Push the top part of the mobile phone in
the direction of arrow 1until it engages in
mobile phone bracket 3.
The mobile phone is connected to the
hands-free system and to the multi-func-
tion steering wheel.
The battery is charged depending on the
charge status and the position of the key in
the ignition lock. The charging process is
shown in the mobile phone display. i
The system reads the phone book stored
on the SIM card and in the mobile phone
memory. If the same entry is stored in both
of the phone books, both of these entries
will be shown in the multi-function display.
You can make a call using the sand
t buttons on the multi-function steering
wheel. You can control other mobile phone
functions via the on-board computer
(Y page 136).
i When you remove the key from the igni-
tion lock, the mobile phone remains
switched on for approximately ten minutes
(run-on time). If you make a call during this
time, the mobile phone will be switched off
approximately ten minutes after you have
ended the call.
Run-on time:
You can change the run-on time by making
an additional phone book entry on the SIM
card. For the name, enter "Idletime" and for
the number, enter a figure between "1" and
"30" (minutes). If you have not entered a
number or have entered a different num-
ber, the run-on time of ten minutes will still
apply. For information on how to create a phone
book entry, refer to the mobile phone oper-
ating instructions.
Own number sending:
The hands-free system does not recognise
whether own number sending is enabled or
disabled in the mobile phone. The phone
number is therefore always sent by default.
By creating an additional phone book entry
on the SIM card, you can switch the own
number sending function on and off. For
the name, enter "CALLID" and for the num-
ber, enter a "0" or a "1". Entering "0" will
prevent the telephone number from being
sent; entering "1" will allow it to be sent.
For information on how to create a phone
book entry, refer to the mobile phone oper-
ating instructions. Controls

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).
If the compass is not calibrated or is malfunc-
tioning due to external interference, you will

In order to calibrate the compass correctly,
observe the following points:
R find a suitable place where you can drive
the vehicle a full circle.
R calibrate the compass in the open and not
in the vicinity of steel constructions or high-
voltage transmission lines. R
switch off electric consumers, e.g.
Thermati c/multi-zone Thermotronic*,
windscreen wipers or rear window heating.
R close all doors and the tailgate.

When calibration is completed, you will see
the following message in the multi-function display:

ted successfully
If you do not see the Compass calibration
Completed successfully message in the
multi-function display, drive another full cir-
cle. If calibration is not successful within
three minutes of it starting, the Compass
calibration message will appear in the
multi-function display again. This means that
compass calibration is impossible because of
external interference. Repeat calibration at
another location. Floormat* on the driver's side

Risk of accident
Make sure that there is sufficient clearance
around the pedals when floormats are
used, and that the floormats are properly
secured.
The floormats must be secured at all times
using retainers and studs.
Before you drive off, make sure that the
floormats are secure and rectify if neces-
sary. A floormat which is not properly
secured can slip and thereby interfere with
the movement of the pedals. Controls
