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 Cont

Risk of accident
Clear all windows of ice or snow before set-
ting off. Impaired visibility could otherwise
endanger you and others.
i At very low temperatures, the rear win-
dow heating is only switched on once the
vehicle interior has warmed up.
i The rear window heating has a high cur-
rent draw. You should therefore switch it
off as soon as the window is clear, as it only
switches off automatically after approxi-
mately six to twenty minutes.
i If the battery voltage is too low, the rear
window heating may switch off.
i Saloon: there are aerial wires in the upper
area of the rear window; this area is there-
fore not heated.

tion mode
You can deactivate the flow of fresh air if
unpleasant odours are entering the vehicle
from outside. The air already inside the vehi-
cle will then be recirculated. G
Risk of accident
Only switch over to air-recirculation mode
briefly at low outside temperatures. Other-
wise, the windows could mist up, thus
impairing visibility and endangering your-
self and others. This may prevent you from
observing the traffic conditions, thereby
causing an accident.

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 141).
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
