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.
Air is cooled as quickly as possible:▷At an external temperature of approx.
32 ℉/0 ℃.▷When the engine is running.
The air volume can be adjusted when the pro‐
gram is active.
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 on the driver's side to utilize the con‐
densation sensor. Make sure that air can flow
onto the windshield.
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.◀

General driving notes
Closing the trunk lid Drive with the trunk lid closed
Only drive with the tailgate closed; other‐
wise, in the event of an accident or braking and
evasive maneuvers, passengers and other road
users may be injured, and the vehicle may be
damaged. In addition, exhaust fumes may en‐
ter the passenger compartment.◀
If driving with the tailgate open cannot be avoided:▷Close all windows and the glass sunroof.▷Greatly increase the blower speed.▷Drive moderately.
Hot exhaust system
Hot exhaust system
High temperatures are generated in the
exhaust system.
Do not remove the heat shields installed and
never apply undercoating to them. Make sure
that flammable materials, e. g. hay, leaves,
grass, etc. do not come in contact with the hot
exhaust system during driving, while in idle po‐
sition mode, or when parked. Such contact
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.◀
Climate control windshield
The marked area is not covered with heat re‐
flective coating.
Use this area for garage door openers, devices
for electronic toll collection, etc.
Climate control laminated tinted
safety glass
The vehicle glass provides full protection
against the harmful effects of UV radiation on
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.

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.
Ground clearance Limited ground clearance
Observe the limited ground clearance of
the vehicle, e. g. while entering underground
parking garages or when driving over obsta‐
cles. Otherwise, damages to the vehicle may
result.◀
To drive down from curbs with the Electronic
Damper Control, refer to page 119, select the
following program, to keep the ground clear‐
ance as even as possible: "Sport Plus"
M Driver's Package: Driving in the
higher speed range
Damage to the vehicle
To ensure problem-free driving behavior
in the maximum speed range, have any dam‐
age to the vehicle repaired as soon as possible
as it could negatively impact driving perform‐
ance. This includes, among other things, tires,
undercarriage and parts for improving aerody‐ namics.
Until the damage is repaired, do not drive the
vehicle in the higher speed range; otherwise,
there is danger of an accident.◀Seite 163Things to remember when drivingDriving tips163

Recommendation
Regardless of wear, replace tires at least every
6 years.
Uniform Tire Quality GradingQuality grades can be found where applicable
on the tire sidewall between tread shoulder
and maximum section width.
For example: Treadwear 200; Traction AA;
Temperature A
DOT Quality Grades
Treadwear
Traction AA A B C
Temperature A B C
All passenger car tires must conform to Fed‐
eral Safety Requirements in addition to these
grades.
TreadwearThe treadwear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled conditions on a specified gov‐
ernment test course. For example, a tire graded 150 would wear one and one-half, 1 g,
times as well on the government course as a
tire graded 100. The relative performance of
tires depends upon the actual conditions of
their use, however, and may depart signifi‐
cantly from the norm due to variations in driv‐
ing habits, service practices and differences in
road characteristics and climate.
Traction
The traction grades, from highest to lowest, are AA, A, B, and C.
Those grades represent the tire's ability to
stop on wet pavement as measured under
controlled conditions on specified governmentSeite 177Wheels and tiresMobility177
