For vehicles which are equipped with the function Coming/Leaving-Home*
⇒ page 53, the side lights also go out. On models fitted with
right-hand steering the position of certain switches differs
from that shown in ⇒fig. 39 . The symbols which mark the switch positions are
identical, however.
In certain countries, the low beam is on a reduced brightness as well as the side
lights, when the ignition is switched on.
WARNING
Never drive with side lights on - risk of accident! The side lights are not
bright enough to light up the road suffic iently in front of you or to be seen by
other oncoming traffic. In this case, always switch on the low beam when it
is dark or if visibility is poor.
Note
•An audible warning will sound if you wi thdraw the ignition key and open the
driver's door when the vehicle lights are still on.
•The acoustic warning signal is switched off over the door contact when the
driver's door is closed (ignition off). The vehicle can be parked with the side lights
on.
•If you park the car for a lengthy period, we recommend switching off all lights,
or leaving only the side lights switched on.
•The switching on of the described lights should only be undertaken in accord-
ance with the legal requirements.
•If a fault occurs in the light switch , the low beam comes on automatically
•In the event of cool or humid weather co nditions, the headlights can be misted
up from inside.
−The temperature difference between interior and external area of the head-
light lenses is decisive.
− When the driving lights are switched on , the light outlet surfaces are free
from mist after a short period. The headlight lenses can possibly mist up at the
border areas.

Note
•Automatic mirror dimming operates only pr operly if the sun screen* for the rear
window is not in use or the light striking the rear of the interior rear-view mirror is
not affected by other objects.
•Do not affix any stickers in front of the light sensor, so that you do not impair the
automatic dimming function or put it out of operation.
•If you switch off the automatic dimming interior rear-view mirror, also the exte-
rior mirror dimming is switched off.

Heating and air conditioning system113

Note
The air outlet vents 2 ensure in the ventilation and cooling mode for a comfortable
(no-draught) ventilation of th e interior of the vehicle, also if the air outlet vents 4
are closed.
Auxiliary heating system (auxiliary heating and
ventilation)*
Description
The auxiliary heating (auxiliary heating and ventilation) heats or
supplies the interior of the vehicl e with fresh air independent of the
engine.
Auxiliary heating (auxiliary heating)
The auxiliary heating (auxiliary heating) f unctions in connection with the heater or
with the Climatic or Climatronic.
It can be used when stationa ry, when engine is switched off for preheating of the
vehicle as well as while driving (e.g. during the heating phase of the engine).
The auxiliary heating (auxiliary heating) warms up the coolant during the combus-
tion of fuel from the vehicle tank. The cool ant warms up the air, which (if the blower
speed is not set to zero) flows into the occupant compartment.
6)
Auxiliary ventilation
The auxiliary ventilation enables fresh air to flow into the vehicle interior by
switching on the blower, if the blower speed is not set to zero, whereby the interior
temperature is effectively decreased (e.g. with a vehicle parked in the sun).
Using the system
So that the auxiliary heating (auxiliary heating and ventilation) func-
tions according to your expectations, it is necessary to carry out the
basic setting before its programming.
Basic setting
– In the information display, select from the menu Main menu the
Menu Setup (settings) ⇒ page 19, fig. 11 .
– In the menu Settings select the menu Aux. Heating (auxiliary
heating).
– In the menu Aux. Heating (auxiliary heating) ⇒ fig. 128 select the
menu Weekday and set the current day.
– Return to a higher level by selecting the menu Back, i. e. in the menu
Aux. Heating (auxiliary heating) .
– In the menu Aux. Heating select the menu Running time and set the
desired operating period in steps of 1 minute. The operating period
can be 5 to 60 minutes.
– Return to a higher level by selecting the menu Back in the menu
Aux. Heating .
6)However the coolant does not warm up the engine.

Rear parking aid*
The parking aid provides a warning of obstacles behind the vehicle.
The audible parking aid determines the distance between the rear bumper and an
obstacle located behind the vehicle with the aid of ultrasound sensors. The sensors
are integrated in the rear bumper.
Range of sensors
The clearance warning begins at a distance of about 160 cm from the obstacle (area
⇒ fig. 135 ). The interval between the warning signals becomes shorter as the
clearance is reduced.
A continuous tone sounds from a clearanc e of just 30 cm (Bereich ) - danger
area. You should not reverse any further after this signal sounds!
For particular model versions, the distance to the obstruction is also displayed on
the display of the radio. You can also switch off this function - see operating instruc-
tions for radio
Activating
The parking aid is activated automatically when reverse gear is engaged and the
ignition is turned on. This is confirmed by a brief acknowledgement signal.
Deactivating
The parking aid is deactivated by removing the reverse gear.
WARNING
•The parking aid is not a substitute for the driver paying proper attention
and it is always the driver's responsibility to take care when parking the
vehicle or carrying ou t similar manoeuvres.
•You should therefore satisfy yourself, before reversing, that there is no
small obstacle, such as a rock, thin po st, trailer drawbar etc., behind your
vehicle. Such an obstacle might not be within the range detected by the
sensors.
Note
•The parking aid does not operate if you are towing a trailer (applies to models
which feature a factory-fi tted towing device*).
•If a warning signal sounds for about 3 seconds after switching the ignition on
and engaging reverse gear, and there is no obstacle close to your car, this indicates
a system fault. Have the fault rectified by a specialist workshop.
•The sensors must be kept clean and free of ice to enable the parking aid to
operate properly.
•If the parking aid is activated and the selector lever of the automatic gearbox is
in the position , warning signal indicates interruption (vehicle can no longer
move).
