In addition the air conditioning dehumidi-
fies the interior air at outside temperatures
above than 41°F (5° C) and helps prevent
window fogging.

only return to its previous position if it
has not been moved to another posi-
tion using the respective window
switch or tilt/sliding sunroof* switch
after it was closed with button:. A
window or tilt/sliding sunroof* that
was moved will remain in its current po-
sition if button: is used to re-open
the remaining windows or tilt/sliding
sunroof*.
iThe air recirculation mode is
deactivated automatically
after five minutes if the outside
temperature is below
approximately 41°F (5°C)
after five minutes if the air condi-
tioning and air-drying is turned off
after 30 minutes if the outside
temperature is above
approximately 41°F (5°C)
iCondensation may drip out from under-
neath the vehicle. This is normal and
not an indication of a malfunction.Warning!

Warning!
G
When closing the windows, make sure that
there is no danger of anyone being harmed
by the closing procedure.
The closing of the door windows can be im-
mediately halted by releasing the switch or,
if switch was pulled past the resistance
point and released, by either pressing or
pulling the respective switch.
The door windows are equipped with the
express-close and automatic reversal
function. If the window encounters an ob-
struction that blocks its path in a circum-
stance where you pulled the switch past the
resistance point and released it to close the
window, the automatic reversal function will
stop the window and open it slightly.
If the window encounters an obstruction
that blocks its path in a circumstance where
you are closing the window by pulling and
holding the switch, by pressing and holding
button‹on the SmartKey, by pressing
and holding the lock button (vehicles with
KEYLESS-GO*) on a door handle, or by
pressing and holding button: on the
climate control panel, the automatic rever-
sal function will not operate.
When leaving the vehicle, always remove the
SmartKey or SmartKey with KEYLESS-GO*
from the starter switch, take it with you, and
lock the vehicle. Do not leave children unat-
tended in the vehicle, or with access to an
unlocked vehicle. Unsupervised use of vehi-
cle equipment can cause an accident
and/or serious personal injury.

238 Controls in detailDriving systemsThe driving systems of your vehicle are de-
scribed on the following pages:
Cruise control, with which the vehicle
can maintain a preset speed.
Downhill Speed Regulation (DSR),
which supports you when you are
driving downhill.
Off-road driving program, which
supports you when you are driving
off-road.
Air suspension package* which adjusts
the vehicle suspension characteristics
automatically and controls the vehicle
level.
Parktronic*, which serves as a parking
aid.
For information on the ABS, BAS, EBB,
ESP®, and 4-ETS driving systems, see
“Driving safety systems” (
page 93).
Cruise control
The cruise control automatically maintains
the speed you set for your vehicle.
Use of cruise control is recommended for
driving at a constant speed for extended
periods of time. You can set or resume
cruise control at any speed above
20 mph (30 km/h).
The cruise control function is operated by
means of the cruise control lever.
The cruise control lever is the uppermost
lever on the left-hand side of the steering
column (
page 22).
iThe cruise control should not be acti-
vated during off-road driving.
Warning!
G
The cruise control is a convenience system
designed to assist the driver during vehicle
operation. The driver is and must remain at
all times responsible for the vehicle speed
and for safe brake operation.
Only use the cruise control if the road,
traffic, and weather conditions make it ad-
visable to travel at a steady speed.
The use of cruise control can be danger-
ous on winding roads or in heavy traffic
because conditions do not allow safe
driving at a steady speed.
The use of cruise control can be danger-
ous on slippery roads. Rapid changes in
tire traction can result in wheel spin and
loss of control.
Deactivate the cruise control when driv-
ing in fog.
The “Resume” function should only be oper-
ated if the driver is fully aware of the previ-
ously set speed and wishes to resume this
particular preset speed.

Warning!
G
The cruise control brakes automatically so
that the set speed is not exceeded. The
brake pedal depresses when the cruise con-
trol engages the brakes.
Keep driver’s foot area clear at all times, in-
cluding the area under the brake pedal. Ob-
jects stored in this area may impair pedal
movement which could interfere with the
braking ability of the cruise control system.
Do not place your foot under the brake pedal
- your foot could become caught.
Keep in mind that the cruise control is a con-
venience system designed to assist the driv-
er during vehicle operation. The driver is and
must always remain responsible for the ve-
hicle’s speed and for safe brake operation.

Canceling cruise control
There are several ways to cancel the cruise
control:
Step on the brake pedal.

iOn uphill grades, the cruise control
may not be able to maintain the set
speed. Once the grade eases, the set
speed will be resumed.
On downhill grades, the cruise control
maintains the set speed with braking
from the vehicle’s braking system. In
addition, on longer downhill grades the
automatic transmission will automati-
cally downshift.
iThe last stored speed is canceled when
you turn off the engine.
