Worn or dirty wiper blades can cause smearing on the glass
which can also impair the effectiveness of the rain sensor. Please
check the wiper blades regularly.
Applies to vehicles: with headlight washersHeadlight washer systemThe headlight washer system only operates when the lights
are switched on.
– Move the automatic wash and wipe lever to position ⇒page 65, fig. 67.The headlight washer system is always activated the first time you
operate the automatic wash and wipe. Subsequently, it is only acti-
vated about every five wash and wipe cycles. The headlights are
always washed if you hold th e lever for longer than about
2seconds.
The headlight washer jets come out of the bumper automatically
(under water pressure).
Clean off stubborn dirt (insects, etc.) from the lenses at regular
intervals, for instance when stopping for fuel.
To ensure that the system works properly in winter, keep the nozzle
holders free of snow and remove any ice with a de-icer spray.
Service position
Use the service position to change the wiper blades.You can set the wipers to the service position on the sound
system or MMI*.
– If the wiper blades are not frozen to the windscreen,
move the windscreen wiper lever to the "off" position

Applies to vehicles: with diesel engineSupplementary heater– Set the Supplementary heater to auto or off .Models with a diesel engine are equipped with a supplementary
heater to help warm up the interior more quickly. At outside temper-
atures below about +5 °C the supple mentary heater is switched on
(and off) automatically when the engine is running, depending on
the coolant temperature, the temperature in the vehicle interior and
the temperature the heater is set to.Deluxe automatic air conditioner plusApplies to vehicles: with deluxe automatic air conditioner plusDescription
The air conditioner is designed to keep the passenger
compartment at the temperature you find most comfort-
able at all times of the year.The air conditioner provides heatin g and ventilation and also cools
and dehumidifies the air inside the vehicle.
The air conditioner is fully automatic, and will maintain the desired
temperature at a constant level. To achieve this, the temperature of
the air supplied to the interior, the blower speed (volume of air
delivery) and the air distribution are regulated automatically. The
system also allows for the effect of strong sunlight, so there is no
need for manual adjustment. For these reasons it is advisable to use
the automatic mode for the comfort of all the passengers in virtually
all conditions throughout the year ⇒page 103 .
Please note:
The humidity of the air is automatically reduced when the system
cools the interior of the vehicle. This helps to prevent condensation
on the windows. If the humidity and temperature outside the vehicle are high,
condensation
can drip off the evaporator in the air cooling system
and form a pool underneath the vehicle. This is normal and does not
indicate a leak.
If the outside temperature is low, the blower normally only switches
to a higher speed once the coolan t has warmed up sufficiently (this
does not apply to the defrost setting).
In order to achieve maximum engine power, the air conditioner
compressor is temporarily switch ed off when pulling away from a
standstill with full throttle.
The compressor also switches of f if the coolant temperature is
excessively high, to ensure adequate engine cooling under extreme
loads.
Pollution filter
The pollution filter (a combined particle filter and activated charcoal
filter) serves as a barrier against impurities in the outside air,
including dust and pollen, and against unpleasant smells. The air is
also filtered when the air recirculation mode is activated.
For the air conditioner to work with maximum efficiency, the pollu-
tion filter element must be replaced at the intervals specified in the
Service Schedule.
If the vehicle is driven in areas with a high level of air pollution and
the filter is no longer fully effective, it may be necessary to change
the filter element more frequently.
Key-coded settings
The currently selected air conditioner settings are automatically
stored and assigned to the remote control key.
Power management
To prevent the battery from becoming discharged and to maintain
the necessary power level, the syst em will temporarily shut off the
electrical components that are usin g a lot of power, or reduce the
current they are consuming ⇒page 226 . Heating systems in partic-
ular use a large amount of electrical power. If you notice, for

– Select: Function selector button > control button AC > e.g. Timer 1 ⇒ page 111, fig. 122.
Activating a timer
– Select: Function selector button > control button AC > Timer status ⇒ fig. 123.Three timers are available for the auxiliary heating/ventilation. You
can set a starting time and running time for each of the timers.
When the time set on one of the ti mers elapses, the date automati-
cally changes to the next day and the Timer status is reset to off. You
have to activate one of the timers (e.g. T1 on) before it will switch on
the auxiliary heating/ventilation at the time you have set. This
prevents the auxiliary heating/ventilation from switching on when
you are not using your vehicle.
Note
Before activating the timer, make su re that the correct time and date
settings have been entered. If the time and/or date are not correct,
the auxiliary heating will come on late or not at all. Please refer to
the MMI Operating Instructions for information on how to set the
date and time.
Applies to vehicles: with auxiliary heating - under development at the time of printingSetting the running time
You can set the running time on the sound system or
MMI*.– Select: Function selector button > control button AC > Running time .The running time for the auxiliary heating/ventilation can be set to

Technical data
•
The control lever has been pushed up / down to increase / reduce
the speed, but the resulting speed would be outside the range of 30
to 200 km/h.
ACC deactivation
The message ACC deactivation sometimes appears on vehicles with
a manual gearbox. If you press the clutch pedal for longer than
about 20 seconds, the adaptive crui se control will be automatically
deactivated and a warning tone will sound.
ACC not available
The text message ACC not available will appear if, for example, the
brakes are overheated. The adaptive cruise control will then tempo-
rarily not be available. This is indicated by a warning tone.
ACC not available!
The text message ACC not available! appears if a malfunction
should occur. The adaptive cruise control will then be switched off.
This is indicated by a warning tone. Have the system checked by a
qualified workshop.
ACC sensor blocked!
The text message ACC sensor blocked! appears if the ACC system
can no longer detect objects reli ably. The adaptive cruise control
will then be switched off. This is indicated by a warning tone.
The ACC sensor is obstructed by dirt or foreign objects (e.g. leaves
or snow). Clean the sensor to restore the function ⇒page 128,
fig. 136.
Engine speed !
On vehicles with manual gearbox, the text message Engine speed !
will appear if the driver does not change gear in time when the
adaptive cruise control accelerates or brakes the vehicle. The adap-
tive cruise control will automatically be deactivated if the engine
speed is not maintained within the permissible range. This is indi-
cated by a warning tone. ESP activation
The text message
ESP activation appears if the Electronic Stabilisa-
tion Programme (ESP) has intervened. In this case, the adaptive
cruise control will automatically be switched off. This is indicated by
a warning tone.
Speed (in km/h)
The target speed (in km/h) will appear in the display whenever it is
stored or changed ⇒page 131, “Setting the speed” and
⇒ page 131, “Setting a new speed”.
Speed range
The text message speed range appears if the current speed is too
low to set or to maintain the target speed.
To set a target speed, the speed of the vehicle must be at least
30 km/h. The cruise control system switches off if the speed falls
below 20 km/h.
If the speed exceeds 200 km/h (OVE RRIDE), the system will remain
active and will reduce the speed to 200 km/h once the driver stops
accelerating.
ACC functionality limited
The text message ACC functionality limited appears if the ACC
system does not detect any objects for an extended period. The
distance to vehicles in front is not being controlled while the
message is displayed. The ACC system is not deactivated, and so
extra care should be taken! The text message ACC functionality
limited can appear for the following reasons:
•
The ACC sensor is dirty. The ACC system is not responding or is
not responding correctly to the vehicles in front!
•
You may be driving on a country road with no traffic and no clear
roadside demarcation (e.g. safety barriers, traffic signs, trees). As
soon as the system detects a vehicle, distance control is resumed
and the text message disappears.
