The DSR is an aid for driving downhill. The
DSR regulates your vehicle’s speed when
driving downhill to the value set in the control
system (Y page 141). The steeper the
downhill gradient is, the greater the brake
application. On flat road surfaces, the DSR
brakes only slightly or not at all.
GWarning!
The Downhill Speed Regulation (DSR) is a
convenience system designed to assist the
driver during vehicle operation. The system
must be set to be appropriate for the
topographical and weather conditions
encountered which can change quickly. The
driver is and must remain at all times
responsible for the vehicle speed and for safe
brake operation.
Depending on the programmed speed, actual
vehicle speed and gradient, switching on the
DSR while driving can cause the vehicle to
slow down rapidly and you may hear a sound
which is caused by the activation of the
vehicle’s brake system through the DSR.
Sudden and unexpected deceleration can
result in loss of vehicle control, causing an
accident and/or serious personal injury to
you and others. Do not switch on the DSR in
a circumstance where rapid deceleration
could result in a loss of vehicle control.
The DSR regulates the vehicle’s speed in
automatic transmission positions D, or R.
iIn addition, make use of the engine’s
braking effect by shifting the automatic
transmission into a lower gear.
You can drive slower or faster than the set
speed at any time by braking the vehicle or
depressing the accelerator pedal.
iWhenever the DSR is switched on, the
DSR will use the programmed default
speed to regulate the vehicle’s speed. The
default speed programmed at the factory is
4 mph (Canada: 6 km/h). The default speed
can be reprogrammed using the control
system (Y page 141). The next time the
DSR is switched on, the DSR will use the
newly programmed default speed to
regulate the vehicle’s speed.
Once the DSR is switched on, you can
adjust the set speed using the cruise
control lever (Y page 145). Keep in mind
that adjusting the set speed using the
cruise control lever with the DSR switched
on will not change the programmed default
speed. If the DSR is switched off and then
switched on again, the DSR will use the
programmed default speed.
Depending on the road surface and level of
downhill grade, the DSR may not be able to
maintain the set speed. To maintain the set
speed, apply the brakes if necessary.

You are responsible for safety at all times and
must continue to pay attention to the
immediate surroundings when parking and
maneuvering. This includes the area behind,
in front of, and beside the vehicle. Otherwise
you could endanger yourself and/or others.
GWarning!

Rthe camera lens is dirty or covered
Rthe rear of your vehicle is damaged
In this case, have the position and setting
of the camera checked by a qualified
specialist workshop. Mercedes-Benz
recommends that you contact a Mercedes-
Benz Center for this purpose.
Do not use the rear view camera in these
situations. Otherwise you could injure
yourself or others and/or damage property
including your vehicle while parking/
maneuvering.
GWarning!
Use of rear view camera can be dangerous if
you are color-blind or have impaired color
vision.
Only use rear view camera if you can see and
distinguish all colored guidelines shown by

Power tilt/sliding sunroof
Opening and closing
GObserve Safety notes, see page 55.GWarning!
When opening or closing the tilt/sliding
sunroof, make sure there is no danger of
anyone being harmed by the opening/closing
procedure.
The tilt/sliding sunroof is equipped with the
express operation and automatic reversal
function. If the movement of the tilt/sliding
sunroof is blocked during the closing
procedure, the tilt/sliding sunroof will stop
and open slightly.
The tilt/sliding sunroof operates differently
when the sunroof switch is pressed and held.
See the “Closing when the tilt/sliding sunroof
is blocked” section for details.
The opening/closing procedure of the tilt/
sliding sunroof can be immediately halted by
releasing the sunroof switch or, if the sunroof
switch was moved past the resistance point
and released, by moving the sunroof switch in
any direction.
GWarning!
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 properly as
entire body parts or portions of them may
protrude from the passenger compartment.
! To avoid damaging the seals, do not
transport 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.
If you cannot open or close the tilt/sliding
sunroof due to a malfunction contact
Roadside Assistance or an authorized
Mercedes-Benz Center.
! 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.
i You can also open or close the tilt/sliding
sunroof using the SmartKey or the
KEYLESS-GO function, see “Summer
opening feature” ( Y page 107) and
“Convenience closing feature”
( Y page 107).
i After switching off the ignition or
removing the SmartKey from the starter
switch, you can operate the tilt/sliding
sunroof until you open the driver’s or front
passenger door. If no door was opened you
can operate the tilt/sliding sunroof for up
to 5 minutes.192Power tilt/sliding sunroofControls in detail
