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.
The tilt/sliding sunroof can be opened or closed
manually should an electrical malfunction occur
(
page 503).
!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.

Driving systems
Switch on the distance warning
function in the control system
(
page 186).
Downhill Speed Regulation (DSR)For more information, see “Off-road driv-
ing” (
page 357).
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 186). 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
If the distance warning lampl in the in-
strument cluster comes on while driving
and/or an intermittent warning sounds,
immediate attention on the part of the driver
is required. As required by the traffic
situation, apply the brakes and navigate
around a possible obstacle. However, do not
drive by relying on the distance warning
function, as this will result in an emergency
braking application. This will not always
enable you to avoid a collision, especially
when traveling on varying road surface
conditions and with varying driver reaction.
Complex driving situations are not always
fully recognized by the distance warning
function. This could result in wrong or miss-
ing distance warnings.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 186), 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.

cross bars are not mounted correctly, they
and the objects attached to them could
come loose from your vehicle and cause an
accident, thereby injuring you and other per-
sons and/or causing damage to property,
including damage to your vehicle.
Warning!G
Every time the basic cross bars are mount-
ed, before you set off on a journey and peri-
odically during longer journeys, check all the
screws on the bars to make sure that they
are secure, and tighten them if necessary.
Repeat these checks at regular intervals as
road-surface conditions dictate, and at least
after every 1500 miles (2500 km) of contin-
uous use.
Otherwise, the basic cross bars, mounted
accessories and the objects attached to
them could come loose from the vehicle
causing an accident, thereby injuring you
and other persons and/or causing damage
to property, including damage to your vehi-
cle.
Do not use lubricant on the screws of the
basic cross bars. The screws could work
loose and the basic cross bars could be-
come detached from your vehicle, together
with the objects attached to them causing
an accident, thereby injuring you and other
persons and/or causing damage to proper-
ty, including damage to your vehicle.
Warning!G
Only install the basic cross bars at the exact
locations designated on the roof rails. The
designated locations for the front basic
