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 on the driver's side to utilize the con‐
densation sensor. Make sure that air can flow

Parked-car ventilation/
heating
The concept The parked-car ventilation ventilates the vehi‐
cle interior and lowers its temperature, if nec‐
essary.
The parked-car heating warms the vehicle in‐
terior, making snow and ice easier to remove.
With the ignition switched off, the air is auto‐
matically routed to the windshield, to the side
windows, and into the footwell.
The systems can be switched on and off di‐
rectly or by using two preset departure times.
The switch-on time is automatically deter‐
mined based on the temperature. The systems
promptly switch on before the selected depar‐
ture time.
Operation takes place on the iDrive or the re‐ mote control.

NoteParked-car heating in enclosed areas
Do not operate the parked-car heating in
enclosed areas, as breathing of the harmful ex‐
haust fumes may lead to loss of consciousness
and death. The exhaust gases contain carbon
monoxide, an odorless and colorless but highly
toxic gas. Switch off the parked-car heating
when refueling.◀
At external temperatures below 32 ℉/0 ℃, wa‐
ter vapor occurs that emerges from below the
vehicle.

could lead to a fire, and with it the risk of seri‐
ous personal injury as well as property dam‐
age.
Do not touch hot exhaust pipes; otherwise,
there is the danger of getting burned.◀

the skin.
Mobile communication devices in thevehicle
Mobile communication devices in the ve‐
hicle
It is advised that you do not use mobile com‐
munication devices, e.g., mobile phones, in‐
side the vehicle without connecting them di‐
rectly to the external antenna. Otherwise, the
vehicle electronics and mobile communication
devices can interfere with each other. In addi‐
tion, there is no assurance that the radiation
generated during transmission will be dis‐
charged from the vehicle interior.◀
Hydroplaning
On wet or slushy roads, a wedge of water can
form between the tires and road surface.
This phenomenon is referred to as hydroplan‐
ing. It is characterized by a partial or complete
loss of contact between the tires and the road
surface, ultimately undermining your ability to
steer and brake the vehicle.
Hydroplaning
When driving on wet or slushy roads, re‐
duce your speed to prevent hydroplaning.◀
Driving through water Drive though calm water only and only if it is
not deeper than. 9.8 inches/25 cm and at this
height, no faster than walking speed, up to 6 mph/10 km/h.
Adhere to water depth and speed limita‐
tions
Do not exceed this water depth and walking
speed; otherwise, the vehicle's engine, the
electrical systems and the transmission may
be damaged.◀
Braking safely
Your vehicle is equipped with ABS as a stand‐
ard feature.
Applying the brakes fully is the most effective
way of braking in situations when this is neces‐
sary.
The vehicle maintains steering responsive‐
ness. You can still avoid any obstacles with a
minimum of steering effort.
Pulsation of the brake pedal and sounds from
the hydraulic circuits indicate that ABS is in its
active mode.Seite 175Things to remember when drivingDriving tips175

Objects in the area around the pedalsNo 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
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 is 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.
