one being harmed by the opening or closing
procedure.
The opening procedure of the tilt/sliding
panel can be immediately halted by releas-
ing the switch or, if the switch was moved
past the resistance point and released, by
moving the switch in any direction.
The closing procedure of the tilt/sliding
panel can be immediately halted by releas-

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.
When leaving the vehicle, always remove the
SmartKey or the SmartKey with
KEYLESS-GO* from the starter switch, take
it with you, and lock the vehicle. Do not
leave children unattended in the vehicle, or
with access to an unlocked vehicle. Unsu-
pervised use of vehicle equipment can
cause an accident and/or serious personal
injury.
!To avoid damaging the seals, do not
transport any objects with sharp edges
which can stick out of the tilt/sliding
panel.
Do not open the tilt/sliding panel if
there is snow or ice on the roof, as this
could result in malfunctions.iYou can also open or close the tilt/slid-
ing panel using the SmartKey or the
KEYLESS-GO* function, see “Summer
opening feature” (
page 251) and
“Convenience closing feature”
(
page 252).
iThe tilt/sliding panel may also open
when using the air recirculation
buttonÄ on the control panel of the
climate control (
page 218) or auto-
matic climate control (
page 232).

disconnected or discharged

after a malfunction

if the tilt/sliding panel does not open
smoothly!Do not attempt to open or close the
tilt/sliding panel before the tilt/sliding
panel is properly synchronized. The
tilt/sliding panel could otherwise
lock-up in the open position.
If the tilt/sliding panel cannot be
closed or synchronized, see an autho-
rized Mercedes-Benz Light Truck
Center or call Roadside Assistance

264 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.

Airmatic* adjusts the vehicle suspen-
sion characteristics automatically and
controls the vehicle level.

Parktronic*, which serves as a parking
assistant.
For information on the BAS, ABS, EBP,
4-ETS and ESP
® driving systems, see “Driv-
ing safety systems” (
page 97).
Cruise control
The cruise control automatically maintains
the speed you set for your vehicle.
The use of cruise control is recommended
for driving at a constant speed for extend-
ed 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).
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 advisable 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.

5 seconds.
Warning!
G
The cruise control brakes automatically so
that the set speed is not exceeded. The
brake pedal is depressed automatically to
do this.
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.
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.
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 active
braking action. In addition, on longer
downhill grades the automatic trans-
mission will automatically downshift.

driving except to coast when the vehi-
cle is in danger of skidding (e.g. on icy
roads).iDepressing the accelerator pedal does
not deactivate the cruise control. After
brief acceleration (e.g. for passing), the
cruise control will resume the last
speed set.
