The panorama roof with power tilt/sliding
panel 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
properly as entire body parts or portions of
them may protrude from the passenger
compartment.
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.
Unsupervised use of vehicle equipment can
cause an accident and/or serious personal
injury.
!To avoid damaging the seals, do not trans-
port 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.
iWhen the tilt/sliding panel is open,
resonance noises may result in addition to the
usual wind noises. They are caused by minimal
pressure changes in the passenger compart-
ment. To reduce or eliminate theses noises,
change the position of the tilt/sliding panel or
open a door window slightly.
iYou can also open or close the tilt/sliding
panel using the SmartKey or the KEYLESS-GO*
function, see “Summer opening feature”
(
page 254) and “Convenience closing
feature” (
page 256).
iThe tilt/sliding panel may also open when
using the air recirculation button:on the
control panel of the climate control
(
page 220) or automatic climate control
(

266 Controls in detail
Driving systems
The driving systems of your vehicle are
described on the following pages:

Cruise control (page 266) and
Distronic* (
page 271), with which
the vehicle can maintain a preset
speed.

Distance warning function*
(
page 284) is only available with
Distronic*, which warns of stationary
obstacles or slower moving vehicles
that you are closing in on too quickly.

AIRMATIC* (page 285) adjusts the
vehicle suspension characteristics
automatically and controls the vehicle
level.

Parktronic* (page 291) and rear view
camera* (
page 295), which serve as
a parking aid.
For information on the ABS, BAS, EBP,
ESP
®, and 4-ETS, see “Driving safety sys-
tems” (
page 100).
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 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 advisable to
travel at a constant speed.

The use of the cruise control can be
dangerous on winding roads or in heavy
traffic because conditions do not allow
safe driving at a constant speed.

The use of the cruise control can be
dangerous on slippery roads. Rapid
changes in tire traction can result in
wheel spin and loss of control.

Deactivate the cruise control when
driving in fog.
The “Resume” function should only be
operated if the driver is fully aware of the
previously set speed and wishes to resume
this particular preset speed.

4Resuming to last set speedActivating cruise control
You can activate the cruise control when
the vehicle speed is above
20 mph (30 km/h).
In the following cases you cannot activate
the cruise control:

when you brake

when you have set the parking brake

when the automatic transmission is set
to positionP, R, or N

if the ESP® is switched off

if the ESP® has switched off due to a
malfunction
Warning!G
The cruise control brakes automatically so
that the set speed is not exceeded. The
brake pedal depresses automatically when
the cruise control engages the brakes.
Keep driver’s foot area clear at all times,
including the area under the brake pedal.
Objects 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
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.
iThe vehicle speed displayed in the speedo-
meter can briefly vary from the speed setting for
the cruise control system.

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 by braking with the vehicle’s
braking system. In addition, on longer downhill
grades the automatic transmission will down-
shift automatically.
iThe last stored speed is canceled when you
turn off the engine.
iThe cruise control switches off
automatically when

you step on the brake pedal

Setting a higher speed
You can increase the set speed in two
ways.
Adjustment in 1 mph (Canada: 1 km/h)
increments
Briefly lift the cruise control lever up to
the resistance point in direction of
arrow1 (
page 267).
Release the cruise control lever.
The vehicle set speed increases in in-
crements of 1 mph (Canada: 1 km/h).Adjustment in 5 mph
(Canada: 10 km/h) increments
!Setting the automatic transmission toN
while driving cancels the cruise control.
However, the automatic transmission should not
be set toN while driving except to coast when
the vehicle is in danger of skidding (e.g. on icy
roads).
iDepressing 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.
iThe set speed value is increased in 1 mph
(Canada: 1 km/h) increments each time you lift
the cruise control lever to the resistance point.
Warning!G
You can increase the vehicle speed in
5 mph (Canada 10 km/h) increments.
When using this feature, keep in mind that it
may take a brief moment until the vehicle
has reached the set speed.
Increase the vehicle set speed to a value
that the prevailing road conditions permit.
Otherwise, sudden and unexpected acceler-
ation of the vehicle could cause an accident
and/or serious injury to you and others.
iThe set speed value is increased in
5 mph (Canada: 10 km/h) increments each time
you lift the cruise control lever past the
resistance point.
