Defrosting windows and removing
condensation
Direct the air distribution toward windows, in‐
crease the air flow and temperature, and, if
necessary, use the cooling function.
Rear window defroster Press the button.
The rear window defroster switches
off automatically after a certain period of time.
Air flow, manual Press the left or right side of the but‐
ton: decrease or increase air flow.
The air flow of the air conditioner may be re‐
duced automatically to save battery power.
AUTO program Press the button.
Air flow, air distribution, and tempera‐
ture are controlled automatically.
Depending on the selected temperature and
outside influences, the air is directed to the
windshield, side windows, upper body, and
into the footwell.
The cooling function, refer to page 145, is
switched on automatically with the AUTO pro‐
gram.
Temperature Turn the wheel to set the de‐sired temperature.
The automatic climate control reaches this
temperature as quickly as possible, if neces‐
sary by increasing the cooling or heating out‐
put, and then keeps it constant.
Avoid rapidly switching between different tem‐
perature settings. Otherwise, the automatic cli‐
mate control will not have sufficient time to ad‐
just the set temperature.
Cooling function The passenger compartment can only be
cooled with the engine running.
Press the button.
The air is cooled and dehumidified
and, depending on the temperature setting,
warmed again.
Depending on the weather, the windshield may
fog up briefly when the engine is started.
The cooling function is switched on automati‐
cally with the AUTO program.
When using the automatic climate control,
condensation water, refer to page 168, devel‐
ops that exits underneath the vehicle.
Recirculated-air mode You can respond to unpleasant odors or pollu‐
tants in the immediate environment by tempo‐
rarily suspending the supply of outside air. The
system then recirculates the air currently within the vehicle.

ton: decrease or increase the inten‐
sity.
The selected intensity is shown on the display
of the automatic climate control.

The system is set to the lowest tem‐
perature, maximum air flow and air circulation
mode.
Air flows out of the vents for the upper body
region. The vents need to be open for this.
The function is available above an external
temperature of approx. 32 ℉/0 ℃ and with the
engine running.
The air flow can be adjusted when the program
is active.
Cooling function

Automatic recirculated-air control/
recirculated-air mode
You can respond to unpleasant odors or pollu‐
tants in the immediate environment by tempo‐
rarily suspending the supply of outside air. The
system then recirculates the air currently
within the vehicle.
Press the button repeatedly to select
an operating mode:▷LEDs off: outside air flows in continuously.▷Left LED on, automatic recirculated-air
control: a sensor detects pollutants in the
outside air and controls the shutoff auto‐
matically.▷Right LED on, recirculated-air mode: the
supply of outside air into the vehicle is per‐
manently blocked.
If the windows are fogged over, switch off the
recirculated-air mode and press the AUTO
button to utilize the condensation sensor.
Make sure that air can flow onto the wind‐
shield.
Continuous recirculated-air mode
The recirculated-air mode should not be
used for an extended period of time, as the air
quality inside the vehicle deteriorates stead‐
ily.◀
Manual air distribution Press the button repeatedly to select
a program:
▷Upper body region.▷Upper body region and footwell.▷Footwell.▷Windows and footwell: driver's side only.▷Windows, upper body region and footwell:
driver's side only.
If the windows are fogged over, press the
AUTO button to utilize the condensation sen‐
sor.
Air flow, manual
To be able to manually adjust the air flow,
switch off the AUTO program first.
Press the left or right side of the but‐
ton: decrease or increase air flow.
The selected air flow is shown on the display of
the automatic climate control.
The air flow of the automatic climate control
may be reduced automatically to save battery
power.
Rear window defroster Press the button.
The rear window defroster switches
off automatically after a certain period of time.
Defrosting windows and removing
condensation
Press the button.
Ice and condensation are quickly re‐
moved from the windshield and the front side
windows.
The air volume can be adjusted when the pro‐
gram is active.
If the windows are fogged over, you can also
switch on the cooling function or press the AUTO button to utilize the condensation sen‐
sor.

Objects within the range of movement
of the pedals
No objects in the area around the pedals
Keep floor mats, carpets, and any other
objects out of the area of motion of the pedals;
otherwise, the function of the pedals could be
impeded while driving and create the risk of an
accident.
Do not place additional floor mats over existing
mats or other objects.
Only use floor mats that have been approved
for the vehicle and can be properly fixed in
place.
Ensure that the floor mats are securely fas‐
tened again after they were removed for clean‐
ing, for example.◀
Driving in wet conditions When roads are wet coated with road salt or
there is heavy rain, briefly exert gentle pres‐
sure on the brake pedal every few miles.
Ensure that this action does not endanger
other road users.
The heat generated in this process helps dry
the brake discs and pads.
In this way braking efficiency will be available
when you need it.
Hills
Drive long or steep downhill gradients in the
gear in which the least braking is required.
Otherwise, the brake system may overheat, re‐
sulting in a reduction in the brake system effi‐
ciency.
You can increase the engine's braking effect
by shifting down, going all the way to first gear,
if necessary.
Avoid load on the brakes
Avoid placing excessive load on the
brake system. Light but consistent brake pres‐
sure can lead to high temperatures, brake wear
and possibly even brake failure.◀Do not drive in neutral
Do not drive in neutral or with the engine
stopped, as doing so disables engine braking.
In addition, steering and brake assist are un‐
available with the engine stopped.◀
Brake disc corrosion The corrosion on the brake discs and the con‐
tamination on the brake pads are furthered by:▷Low mileage.▷Extended periods when the vehicle is not
used at all.▷Infrequent use of the brakes.
Corrosion occurs when the minimum pressure
that must be exerted by the pads during brake
applications to clean the discs is not reached.
Should corrosion form on the brake discs, the
brakes will tend to respond with a pulsating ef‐
fect that generally cannot be corrected.
Condensation under the parked
vehicle
When using the automatic climate control,
condensation water develops that exits under‐
neath the vehicle.
Traces of water under the vehicle like this are
normal.

Danger of burns
Only change bulbs when they are cool;
otherwise, there is the danger of getting
burned.◀
Working on the lighting system
When working on the lighting system,
you should always switch off the lights af‐
fected to prevent short circuits.
To avoid possible injury or equipment damage
when replacing bulbs, observe any instructions
provided by the bulb manufacturer.◀
Do not perform work/bulb replacement
on xenon headlamps
Have any work on the xenon lighting system,
including bulb replacement, performed only by
a service center. Due to the high voltage
present in the system, there is the danger of
fatal injuries if work is carried out improperly.◀
Do not touch the bulbs
Do not touch the glass of new bulbs with
your bare hands, as even minute amounts of
contamination will burn into the bulb's surface
and reduce its service life.
Use a clean tissue, cloth or something similar,
or hold the bulb by its base.◀
Light-emitting diodes (LEDs)
Light-emitting diodes installed behind a cover
serve as the light source for controls, display
elements and other equipment.
These light-emitting diodes, which are related
to conventional lasers, are officially designated as Class 1 light-emitting diodes.
Do not remove the covers
Do not remove the covers, and never
stare into the unfiltered light for several hours; otherwise, irritation of the retina could result.◀Headlamp glass
Condensation can form on the inside of the ex‐
ternal lamps in cool or humid weather. When
driving with the light switched on, the conden‐
sation evaporates after a short time. The head‐
lamp glasses do not need to be changed.
If the headlamps do not dim despite driving
with the light switched on, increasing humidity
forms, e. g. water droplets in the light, have the
service center check this.
Headlamp setting
The headlamp adjustments can be affected by
changing lamps and bulbs. Therefore after a
change, have the headlamp setting checked
and corrected by Service.
