Power tilt/sliding sunroof*
Opening and closing
Warning!G
When closing the tilt/sliding sunroof, make
sure that there is no danger of anyone being
harmed by the closing procedure.
If the tilt/sliding sunroof encounters an
obstruction that blocks its path in a circum-
stance where you are closing the tilt/sliding
sunroof by moving the tilt/sliding sunroof
switch past the resistance point, or by

and released, by moving the switch in any
direction.
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.
When leaving the vehicle, always remove the
SmartKey or SmartKey with KEYLESS-GO*
from the starter switch, take it with you, and
lock your vehicle. Do not leave children
unattended in the vehicle, or with access to
an unlocked vehicle. A child’s unsupervised
access to a vehicle could result in 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 sunroof.
Do not open the tilt/sliding sunroof if there is
snow or ice on the roof, as this could result in
malfunctions.
!Please keep in mind that weather conditions
can sometimes change rapidly. Make sure to
close the tilt/sliding sunroof when leaving the
vehicle. If water enters the vehicle interior,
vehicle electronics could be damaged which is
not covered by the Mercedes-Benz Limited
Warranty.
iWhen the tilt/sliding sunroof 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 sunroof or
open a door window slightly.

Driving systems
Driving systems
The driving systems of your vehicle are
described on the following pages:

Cruise control (page 257) and
Distronic* (
page 262), with which
the vehicle can maintain a preset
speed.

Distance warning function*
(
page 275) is only available with
Distronic*, which warns of stationary
obstacles or slower moving vehicles
that you are closing in on too quickly.

AIRMATIC* (page 276) adjusts the
vehicle suspension characteristics
automatically and controls the vehicle
level.

Parktronic* (page 281) and rear view
camera* (
page 285), which serve as
a parking aid.
For information on the ABS, BAS, EBP,
ESP
®, and 4-ETS, see “Driving safety sys-
tems” (
page 99).
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.

Driving systems
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 responsibility for the vehicle’s speed,
distance to the preceding vehicle and, most
importantly, brake operation to ensure a
safe stopping distance, always remains with
the driver.
Distronic cannot take road and traffic condi-
tions into account.
Complex driving situations are not always
fully recognized by Distronic. This could
result in wrong or missing distance
warnings.
Warning!G
Distronic adaptive cruise control is no
substitute for active driving involvement. It
does not react to pedestrians or on station-
ary objects, nor does it recognize or predict
the lane curvature or the movement of
preceding vehicles.
Distronic can only apply a maximum of 20%
of the vehicle’s braking power.
It is the driver’s responsibility at all times to
be attentive to the road, weather and traffic
conditions. Additionally, the driver must
provide the steering, braking and other
driving inputs necessary to remain in control
of the vehicle.
High-frequency sources such as toll
stations, speed measuring systems etc. can
cause the Distronic system to malfunction.
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.
Warning!G
Distronic cannot take road and traffic condi-
tions into account. Only use Distronic if the
road, weather and traffic conditions make it
advisable to travel at a constant 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.

Vehicle care
Cleaning the panorama roof with
tilt/sliding panel*
The rear part of the panorama roof has a
protective layer on the inside.
Use a soft, clean cloth and a mild
window cleaning solution.
An automotive glass cleaner is recom-
mended.Light alloy wheels
If possible, clean wheels once a week.
Use Mercedes-Benz approved Wheel
Care, a soft bristle brush and a strong
spray of water for cleaning the light al-
loy wheels.Plastic and rubber parts
Use a gentle dishwashing detergent or
mild detergent for delicate fabrics as a
washing solution.
Wipe with a cloth moistened in a luke-
warm solution.
The surface may temporarily change
color. If this is the case, wait for it to
dry.
!Do not use a dry cloth, abrasives, solvents
or cleaners containing solvents. Do not touch
the protective layer with hard objects such as an
ice scraper or ring. Never apply strong force and
only use a soft, non-scratching cloth when clean-
ing the rear part of the tilt/sliding panel*.
Otherwise you may scratch or damage the
protective layer.
!Only use acid-free cleaning materials. Acid
may cause corrosion or damage the clear coat.
!The vehicle should not be parked for an
extended period of time immediately after it has
been cleaned, especially not after the wheel rims
have been cleaned with wheel rim cleaner.
Wheel rim cleaners can lead to increased
corrosion of the brake disks and brake pads.
Non-approved wheel cleaners may also damage
the wheel paint if the car is not driven after
cleaning. Therefore, the vehicle’s brake system
should always be warmed-up before it is parked
after cleaning. To do so, please drive your vehicle
for several minutes to allow the brakes to dry.
When applying Mercedes-Benz approved Tire
Care and Mercedes-Benz approved Wheel Care
products, take care not to spray them on the
brake disks.
Warning!G
Do not use cleaners containing solvents or
cockpit care sprays to clean the cockpit or
the steering wheel. Cleaners containing sol-
vents will make the surface porous and vehi-
cle occupants could suffer serious injuries
from plastic parts coming loose in the event
of air bag deployment.
