When closing the tilt/sliding sunroof, make
sure there is no danger of anyone being
harmed by the closing procedure.
The opening/closing procedure of the
tilt/sliding sunroof can be immediately halt-
ed by releasing the switch or, if the switch
was moved past the resistance point and
released, by moving the switch in any direc-
tion.
The tilt/sliding sunroof is made out of glass.
In the event of an accident, the glass may
shatter. This may result in an opening in the
roof.
In a vehicle rollover, occupants not wearing
their seat belts or not wearing them properly
may be thrown out of the opening. Such an
opening also presents a potential for injury
for occupants wearing their seat belts prop-
erly as entire body parts or portions of them
may protrude from the passenger compart-
ment.

Driving systems
The following driving systems are
explained on the following pages:
Cruise control and Distronic*, with
which the vehicle can maintain a preset
speed
Airmatic DC adjusts the vehicle sus-
pension characteristics automatically
and controls the vehicle level
Parktronic system*, which assists the
driver during parking maneuvers
For information on the BAS, ABS, ESP
® and
EBP, see “Driving safety systems”
(
page 91).
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 24).
Warning!
G
The cruise control is a convenience system
designed to assist the driver during vehicle
operation. The driver is and must always
remain responsible for the vehicle’s 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.

The selected speed appears in the multi-
function display for approximately
5 seconds, and the corresponding speed-
ometer segments from the selected speed
to the vehicle maximum speed are illumi-
nated.
Warning!
G
The cruise control brakes automatically so
that the set speed is not exceeded.
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.
i
On uphill or downhill grades, the cruise con-
trol may not be able to maintain the set speed.
Once the grade eases, the set speed will be re-
sumed.
On downhill grades, the cruise control maintains
the set speed with active braking action. In addi-
tion, on longer downhill grades the automatic
transmission will automatically downshift.

Canceling cruise control
There are several ways to cancel the cruise
control:
Step on the brake pedal.
The cruise control is canceled. The last
speed set is stored for later use.
or
Briefly push the cruise control lever in
direction of arrow3 (
page 216).
The cruise control is canceled. The last
speed set is stored for later use.Setting a higher speed
Lift the cruise control lever in direction
of arrow1 (
page 216) and hold it
up until the desired speed is reached.
Release the cruise control lever.
The new speed is set.
Setting a lower speed
Depress the cruise control lever in
direction of arrow2 (
page 216) and
hold it down until the desired speed is
reached.
Release the cruise control lever.
The new speed is set.

The last stored speed is canceled when you
turn off the engine.

!
Moving the gear selector lever to positionN
while driving also cancels the cruise control.
However, the gear selector lever should not be
moved to positionN while driving except to
coast when the vehicle is in danger of skidding
(e.g. on icy roads).
i
Depressing the accelerator pedal does not
deactivate the cruise control. After brief acceler-
ation (e.g. for passing), the cruise control will re-
sume the last speed set.
i
When you use the cruise control lever to de-
celerate, the brake system will automatically
brake the vehicle if the engine’s braking power
does not brake the vehicle sufficiently.

Distronic*
When activated, the Distronic adaptive
cruise control system increases driving
convenience afforded by the cruise control
during travel on expressways and other
major roads.
If the Distronic distance sensor detects
a slower moving vehicle directly ahead,
your vehicle speed will be reduced so
that you follow that vehicle at a preset
distance.
If there is no vehicle directly ahead of
you, Distronic will function in the same
way as cruise control (
page 216).
Warning!
G
The speed stored in memory should only be
set again if prevailing road conditions per-
mit. Possible acceleration or deceleration
differences arising from returning to the pre-
set speed could cause an accident and/or
serious injury to you and others.
Warning!
G
Distronic adaptive cruise control is no sub-
stitute for active driving involvement. It does
not react to stationary objects, nor recog-
nize or predict the curvature and lane layout
or the movement of vehicles ahead.
Distronic can only apply a maximum of 20%
of the vehicle’s braking power.

Driving systems
It is the driver’s responsibility at all times to
be attentive to road, traffic, and weather
conditions and to provide the steering, brak-
ing and other driving inputs necessary to re-
tain control of the vehicle.Warning!
G
Distronic is a convenience system. Its speed
adjustment reduction capability is intended
to make cruise control more effective and
usable when traffic speeds vary. It is not
however, intended to, nor does it, replace
the need for extreme care. The responsibili-
ty for the vehicle speed and the distance to
the vehicle ahead, including most impor-
tantly brake operation to assure safe stop-
ping distance, always rests with the driver.
Distronic cannot take street and traffic con-
ditions into account.
Warning!
G
Distronic requires familiarity with its opera-
tional characteristics. We strongly recom-
mend that you review the following
information carefully before operating the
system.i
USA only: This device has been approved by
the FCC as a “Vehicular Radar System”. The ra-
dar sensor is intended for use in an automotive
radar system only. Removal, tampering, or alter-
ing of the device will void any warranties, and is

220 Controls in detailDriving systemsWarning!
G
Distronic cannot take street and traffic con-
ditions into account. Only use Distronic if
the road, weather and traffic conditions
make it advisable to travel at a steady
speed.Warning!
G
Use of Distronic can be dangerous on slip-
pery roads. Rapid changes in tire traction
can result in wheel spin and loss of control.
Distronic does not act upon adverse sight
distance conditions. Do not use Distronic
during conditions of fog and heavy rain,
snow or sleet.
Warning!
G
Distronic cannot take weather conditions
into account. Switch off Distronic or do not
turn it on if:
roads are slippery or covered with snow
or ice. The wheels could lose traction
while braking or accelerating, and the
vehicle could skid
the sensor is dirty or visibility is
diminished due to snow, rain or fog. The
distance control could be impaired
Always pay attention to traffic conditions
even while Distronic is switched on. Other-
wise, you may not be able to recognize
dangerous situations until it is too late and
could cause an accident resulting in person-
al or fatal injury to you or others.
Warning!
G
Close attention to road and traffic condi-
tions is imperative at all times, regardless of
whether or not Distronic is activated.
Use of Distronic can be dangerous on wind-
ing roads or in heavy traffic because condi-
tions do not allow safe driving at a steady
speed.
Distronic will not react to stationary objects
in the roadway (e.g. a stopped vehicle in a
traffic jam or a disabled vehicle). Distronic
will also not respond to oncoming vehicles.
Switch off Distronic:
when changing from the left to the right
lane if vehicles are moving more slowly
in the left lane
when entering a turn lane or highway off
ramp
in complex driving situations, such as in
highway construction zones
In these situations, Distronic will continue to
maintain the set speed unless deactivated.
