The rear window heater only operates when the engine is running.
The rear window heater switches off automatically after 10 minutes. For the sake of the environment
As soon as the window is de-iced or free from mist, the heating should be switch-
ed off. The reduced current consumption will have a favourable effect on fuel
economy ⇒ page 165, Saving electricity. Note
● If the on-board voltage drops, the rear window heater switches off automati-
cally, in order to provide sufficient electrical energy for the engine control
⇒

CAUTION
● In cold temperatures and in winter, check before the trip or before switching
on the ignition that the wiper blades are not frozen. Switching on windscreen
wipers when the blades are frozen to the windscreen may result in damage both
to the blades and the motor of the windscreen wipers!
● If you switch off the ignition while the windscreen wipers are on, the wipers
will sweep in the same mode the next time the ignition is switched on. At low
temperatures, the wipers may freeze to the window between switching off the ig-
nition and the next time you switch the ignition on again.
● Carefully detach frozen wiper blades from the front or rear window.
● Remove snow and ice from the window wipers before driving. Note
● If the slower 2 or the faster
3 wiper setting is switched on
⇒  fig. 37 and the
vehicle speed decreases to below 4 km/h, the lower wiper step is switched on au-
tomatically. At a speed increase of more than 8 km/h the previous wiper setting is
established again.
● If there is an obstacle on the windscreen, the wiper will try to push away the
obstacle. If the obstacle continues to block the wiper, the wiper stops automati-
cally after 5 attempts to eliminate the obstacle, in order to avoid a damage to the
wiper. Remove the obstacle and and switch on the wiper again.
● The windscreen washer nozzles for the windscreen are heated when the en-
gine is running and the outside temperature is less than +10
°C.
● The content of the windscreen wiper reservoir is 3 litres. On vehicles which are
equipped with a headlight cleaning system, the content of the reservoir is 5.5
li-
tres. On vehicles fitted with auxiliary heating, the content of the windscreen wiper
reservoir is 4.5 litres. 
Automatic rear window wiper (Estate car) If the windshield wiper is in positions
2
⇒  fig. 37 or 3 the rear view window is
wiped every 30/10 seconds if the vehicle's speed exceeds 5 km/h.
When the rain sensor is active (the lever is in the position 1 ) the function is only
active if the front window wipers continue to operate (no break between each
wiping process). Activation/deactivation
The function of the automatic rear window wiper is activated/deactivated in the
information display in the menu:
■ Settings
■ Lights & Vision
■ Rear wiper Note
The function of the automatic rear window wiper is only valid for Estate car vehi-
cles which are equipped with an information display. The function is activated in
the factory. 
Headlight cleaning system The headlights are being cleaned after the windscreen has been sprayed for the
first time and fifth time, the low beam or main beam are switched on and the
windscreen wiper lever was held in the position 5
⇒  fig. 37 for about 1 second.
The headlight washer nozzles are moved forward out of the bumper by the water
pressure for cleaning the headlights.
You should remove stubborn dirt (such as insect residues) from the headlight len-
ses at regular intervals, for example when refuelling. Please refer to the following
guidelines ⇒

  page 172, The headlight lenses.
You should remove any snow from the fixtures of the washer nozzles and clear ice
in winter with a de-icing spray in order to ensure proper operation of the cleaning
system. CAUTION
Never remove the nozzles from the headlamp cleaning system by hand - risk of
damage!  55

Heating and air conditioning system Using the system Safety Driving Tips General Maintenance Breakdown assistance Technical data

The cooling only operates if button
AC ⇒ 
fig. 94 1 is pressed, and the following
conditions are met:
● engine running,
● outside temperature above approx. +2 °C and
● blower switch switched on (positions 1 to 4).
Air at a temperature of about 5 °C may flow out of the vents under certain circum-
stances when the cooling system is operating. Lengthy and uneven distribution of
the air flow out of the vents and large differences in temperature, for example
when getting out of the vehicle, can result in chills in sensitive persons. Note
● We recommend that you have the air conditioning system cleaned by a spe-
cialist garage once every year. 

perature is regulated automatically within this range. If you chose a temperature
lower than +18 °C, a blue symbol lights up at the start of the numerical scale. If you
chose a temperature higher than +26 °C, a red symbol lights up at the end of the
numerical scale. In both limit positions the Climatronic operates at maximum cool-
ing or heating capacity, respectively. The temperature is not controlled in this
case.
Lengthy and uneven distribution of the air flow out of the vents (in particular at
the leg area) and large differences in temperature, for example when getting out
of the vehicle, can result in chills in sensitive persons. 92
Heating and air conditioning system

Auxiliary heating (auxiliary heating and ventilation)
Description and important information The auxiliary heating (auxiliary heating and ventilation) heats or
supplies the interior of the vehicle with fresh air independent of the
engine.
Auxiliary heating (parking heating)
The auxiliary heater (parking heater) functions in connection with the air-condi-
tioning system or Climatronic.
It can be used when stationary, 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 engine is also preheated when the vehicle is stationary and the engine is
switched off, if the auxiliary heating is switched on.
The auxiliary heating (parking heating) warms up the coolant during the combus-
tion of fuel from the vehicle tank. The coolant warms up the air, which (if the
blower speed is not set to zero) flows into the occupant compartment.
Auxiliary ventilation
The auxiliary ventilation enables fresh air to flow into the vehicle interior by
switching off the engine, whereby the interior temperature is effectively de-
creased (e.g. with the vehicle parked in the sun). WARNING
● The auxiliary heating must never be operated in closed rooms - risk of poi-
soning!
● The auxiliary heating must not be running during refueling - risk of fire.
● The exhaust pipe of the auxiliary heating is located on the underside of
the vehicle. Therefore do not place the vehicle, if you wish to operate the aux-
iliary heating, in such a way that the exhaust gases of the auxiliary heating
can come easily into contact with inflammable materials (e.g. dry grass) or
easily inflammable substances (e.g. fuel run out). Note
If the auxiliary heating runs, the fuel consumption comes from the vehicle tank.
The auxiliary heating automatically controls the filling level in the fuel tank. If only
a low quantity of fuel is present in the fuel tank, the function of the auxiliary heat-
ing is blocked.
● The exhaust pipe of the auxiliary heating, which is located on the underside of
the vehicle, must not be clogged and the exhaust flow must not be blocked.
● If the auxiliary heating and ventilation is running, the vehicle battery discharg-
es. If the auxiliary heating and ventilation has been operated several times over a
longer period, the vehicle must be driven a few kilometers in order to recharge the
vehicle battery.
● The auxiliary heating only switches the blower on, if it has achieved a coolant
temperature of approx. 50 °C.
● At low outside temperatures, this can result in a formation of water vapour in
the area of the engine compartment. This is quite normal and is not an operating
problem.
● After switching off the auxiliary heating, the coolant pump runs for a short pe-
riod.
● The auxiliary heating and ventilation does not switch on or comes on, if the
vehicle battery indicates a low loading state ⇒

shut-off.
● The auxiliary heating (parking heating) does not switch on, if the following was
shown in the information display or before switching off the ignition: Please re-
fuel!
● The air inlet in front of the windscreen must be free of ice, snow or leaves in
order to ensure that the auxiliary heating operates properly.
● So that warm air can flow into the vehicle interior after switching on the auxili-
ary heating, you must maintain the comfort temperature normally selected by you
and leave the air outlet vents in an open position. It is recommended to put the air
flow in the position  or . 94
