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 ob-
struction 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
pressing and holding button‹ on the
SmartKey, by pressing and holding the lock
button (vehicles with KEYLESS-GO*) on the
door handle, the automatic reversal function
will not operate.
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 re-
leased, 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.
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 un-
attended 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, reso-
nance noises may result in addition to the usual
wind noises. They are caused by minimal pres-
sure changes in the passenger compartment. To
reduce or eliminate these noises, change the po-
sition of the tilt/sliding sunroof or open a side
window slightly.
iYou can also open or close the tilt/sliding
sunroof using the SmartKey or the
KEYLESS-GO* function, see “Summer opening
feature” (
page 237) and see “Convenience
closing feature” (
page 238).

Driving systems
Setting to last stored speed
(“Resume” function)
Briefly pull the cruise control lever in di-
rection of arrow4 (
page 245).
The cruise control resumes to the last
set speed, or if no speed is stored, it
will set and store the current speed.
Remove your foot from the accelerator
pedal.
The last set speed appears in the multi-
function display for approximately
5seconds.
Downhill Speed Regulation (DSR)For more information, see “Off-road driv-
ing” (
page 319).
The DSR is an aid for driving downhill. DSR
regulates your vehicle’s speed when driv-
ing downhill to the value set in the control
system (
page 178). The steeper the
downhill gradient is, the greater the brake
application. On flat road surfaces, DSR
brakes only slightly or not at all.
DSR regulates the vehicle’s speed in auto-
matic transmission positionsD, orR.
You can drive slower or faster than the set
speed at any time by braking the vehicle or
depressing the accelerator pedal.
Warning!G
The set speed stored in memory should only
be set again if prevailing road conditions
permit. Possible acceleration or decelera-
tion differences arising from returning to the
preset speed could cause an accident
and/or serious injury to you and others.
Warning!G
Downhill Speed Regulation 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 vehi-
cle speed and for safe brake operation.
Depending on the programmed speed
(
page 178), actual vehicle speed and gra-
dient, 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 sys-
tem through the DSR. Sudden and unex-
pected 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.
iIn addition, make use of the engine’s braking
effect by shifting the automatic transmission
into a lower gear.

If only the red distance segments illumi-
nate and an acoustic warning sounds,
there is a malfunction in the Parktronic
system. The Parktronic system will auto-
matically switch off after 20 seconds and
the indicator lamp in the Parktronic switch
comes on.
Have the Parktronic system checked
by an authorized Mercedes-Benz Light
Truck Center as soon as possible.
If only the red distance segments illumi-
nate and no acoustic warning sounds, the
Parktronic system sensors are dirty (e.g.
slush, snow or ice) or there is an interfer-
ence from other radio or ultrasonic signals
(e.g. working jackhammers, car wash or
the air brakes of trucks). The Parktronic
system will automatically switch off after
20 seconds and the indicator lamp in the
Parktronic switch comes on.iThe Parktronic system switches on
automatically when you switch on the ignition

Rear view camera*
Warning!G
The rear view camera is only an aid and may
display obstacles from a distorted perspec-
tive or inaccurately, or may not display ob-

Loading instructions
Warning!G
Only use carriers* when the basic carrier
bars* have been completely mounted. The
left and right roof rails are only stabilized by
means of the basic carrier bars* mounted.
Follow the manufacturer’s installation
instructions. Otherwise, an improperly at-
tached carrier system or its load could be-
come detached from the vehicle.
Do not exceed the maximum roof load of
220 lb (100 kg).
Take into consideration that when the roof is
loaded, the handling characteristics are dif-
ferent from those when operating the vehi-
cles without a roof loaded.
!Load the carriers* in such a way that the
vehicle cannot be damaged while driving.
Make sure

the tailgate can be completely opened

the tilt/sliding sunroof can be completely
raised at the rear
Warning!G
Always fasten items being carried as secure-
ly as possible using cargo tie-down rings and
fastening materials appropriate for the
weight and size of the load.
In an accident, during hard braking or sud-
den maneuvers, loose items will be thrown
around inside the vehicle, and can cause in-
jury to vehicle occupants unless the items
are securely fastened in the vehicle.
To help avoid personal injury during a colli-
sion or sudden maneuver, always use tie
down rings, and if so equipped, always use
the cargo net* when transporting cargo.
Never drive vehicle with the tailgate open.
Deadly carbon monoxide (CO) gases may
enter vehicle interior resulting in uncon-
sciousness and death.

cargo.
Unless you are transporting cargo, the back-
rests must remain properly locked in the up-
right position.
In an accident, during hard braking or sud-
den maneuvers, loose items will be thrown
around inside the vehicle, and can cause
injury to vehicle occupants unless the items
are securely fastened in the vehicle.
Always use the cargo tie down rings
(

Warning!G
Never drive the vehicle with the tailgate
open. Deadly carbon monoxide (CO) gases
may enter vehicle interior resulting in un-
consciousness and death.
!Always release the seat cushion and fold it
up before folding the seat backrest forward. The
covering on the seat backrest may otherwise be
damaged.
When the seat backrest are folded forward, the
front seats may not be moved to the rearmost
position. Otherwise you could damage the front
and second-row seats.
