Switch to the right high sensitivity.
Switch to the left low sensitivity.

WARNING
The rain/light sensor cannot always adequately detect all precipitation and activate the wipers
correspondingly.
If necessary, switch on the wipers manually in good time if the water on the windscreen restricts the
field of vision.

Some settings can be stored in the user accounts of the personalisation function and therefore
change automatically when the user account changes

Changes in the activation behaviour of the rain/light sensor
Possible causes for faults and misinterpretations relating to the sensitive surface of the rain/light
sensor
Damaged wiper blades: a film of water or smears caused by damaged wiper blades can increase the
time the wipers are switched on, can shorten the length of the intervals between wipes or cause the
wipers to run quickly and continuously.
Insects: insects hitting the windscreen can cause the wipers to be activated.
Salt deposits: in winter, salt deposits can cause the wipers to continue to wipe the windscreen when
it is almost dry.
Dirt: dry dust, wax, windscreen coatings (lotus effect), or detergent deposits (from an automatic car
wash) can cause the rain/light sensor to become less sensitive and react too slowly, or prevent it
from reacting at all. Clean the sensitive surface of the rain/light sensor Caring for and cleaning the
vehicle exteriorat regular intervals and inspect the wiper blades for damage.
Crack in the windscreen: a wipe cycle will be triggered if the rain/light sensor is on when the
windscreen is impacted by a stone. The rain/light sensor will then register the impairment of the
sensitive surfaces and adjust accordingly. Depending on the size of the stone impact, the activation
behaviour of the rain/light sensor may be changed.
We recommend that you use an alcohol-based glass cleaner to remove wax and polish.

The wipers will try to wipe away any obstacles that are on the window. The wiper will stop moving if
the obstacle continues to block its path. Remove the obstacle and switch the wiper back on again.

Auxiliary heater and ventilation
Introduction
This chapter contains information on the followingsubjects:
Switching the auxiliary heater and ventilation on and off
Programming the auxiliary heater and ventilation
Remote control
The auxiliary heater and ventilation system can be used to heat the vehicle interior in the winter and
ventilate it in the summer. It is able to clear ice, condensation and a thin layer of snow from the
windscreen. The auxiliary heater is supplied with fuel from the vehicle fuel tank and can be operated
when the vehicle is stationary with the ignition switched off. The auxiliary ventilation system is
powered by the 12-volt vehicle battery.
Auxiliary heater exhaust system
The emissions generated by the auxiliary heater are discharged via an exhaust pipe underneath the
vehicle. The exhaust pipe must not be blocked by snow, mud or other objects.

WARNING
Among other things, the emissions from the auxiliary heater contain carbon monoxide, which is an
odourless and colourless poisonous gas. Carbon monoxide can cause people to lose consciousness. It
can also cause death.
Never switch on the auxiliary heater when the vehicle is in unventilated or closed rooms nor let the
auxiliary heater run in unventilated or closed rooms.
Never program the auxiliary heater so that it is switched on and runs in unventilated or closed
rooms.

WARNING
Parts of the auxiliary heater exhaust system become very hot. This can cause fires.
Park the vehicle so that no part of the exhaust system can come into contact with any inflammable
material underneath the vehicle, e.g. dry grass.

Food, medicine and other items that are sensitive to heat or cold could be either damaged or
rendered useless by the air flowing out of the vents.
Never leave food, medicines or other temperature-sensitive objects in front of the vents.
Switching the auxiliary heater and ventilation on and off
First read and observe the introductoryinformation and safety warnings
The auxiliary heater can be operated only when the ignition is switched off. If the ignition is switched
on while the auxiliary heater is working, the auxiliary heater continues to run to provide additional
heat.
Switching on the auxiliary heater

The auxiliary heater runs on for a short time after it has been switched off manually or automatically
so that the remaining fuel in the system can be burnt off.

When the vehicle is at a standstill, the auxiliary heater can be activated up to three times in
succession for the maximum operating duration.

e date and time set in the vehicle are correct Time
Open the Auxiliary heater menu.
Touch the Set function button.
Select one of the memory locations for a Departure time.
Touch the Activate function button.
Manual air conditioning system: the programmed departure time determines the time at which
the auxiliary heater or ventilation should switch off. The point at which the heating or ventilation
process starts is determined depending on the programmed running time.
Climatronic: on the basis of the programmed departure time, the vehicle automatically
calculates the start time for heating or ventilation to the currently set temperature depending on
the outside temperature.
Press the Running time function button under Adjust in order to select the running time when the
auxiliary heater is switched on using the immediate heat button or remote control.
Checking programming
If a departure time has been activated, the LED in the immediate heat button will light up on the
Climatronic control panel for approximately 10 seconds after the ignition is switched off.

WARNING
Never program the auxiliary heating system so that is switched on and run in unventilated or
enclosed spaces. Among other things, the emissions from the auxiliary heater contain carbon
monoxide, which is an odourless and colourless poisonous gas. Carbon monoxide can cause people
to lose consciousness. It can also cause death.
