G WARNING
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. If the tailgate
is open when the engine is running, particu-
larly if the vehicle is moving, exhaust fumes
could enter the passenger compartment.
There is a risk of poisoning.
Turn off the engine before opening the tail-
gate. Never drive with the tailgate open.
G WARNING
If objects, luggage or loads are not secured or
not secured sufficiently, they could slip, tip
over or be flung around and thereby hit vehicle
occupants. There is a risk of injury, particu-
larly in the event of sudden braking or a sud-
den change in direction.
Always store objects so that they cannot be
flung around. Secure objects, luggage or
loads against slipping or tipping before the
journey.
! The tailgate swings upwards and to the
rear when opened. Therefore, make sure
that there is sufficient clearance above and
behind the tailgate.
The opening dimensions of the tailgate can be
found in the "Vehicle data" section
( Y

You should preferably place luggage or loads
in the cargo compartment. Observe the load-
ing guidelines ( Y

G WARNING
At high speeds the raised sliding sunroof auto-
matically lowers slightly at the rear. This could
trap you or other persons. There is a risk of
injury. Make sure that nobody reaches into
the sweep of the sliding sunroof whilst the
vehicle is in motion.
If somebody becomes trapped, immediately
pull back the sliding sunroof switch. The slid-
ing sunroof lifts during opening.
! Only open the sliding sunroof if it is free of
snow and ice. Otherwise, malfunctions may
occur.
Do not allow anything to protrude from the
sliding sunroof. Otherwise, the seals could
be damaged.
! The weather can change abruptly. It could
start to rain or snow. Make sure that the
sliding sunroof is closed when you leave the
vehicle. The vehicle electronics can be
damaged if water enters the vehicle inte-
rior.
i Resonance noises can occur in addition to
the usual airflow noises when the sliding
sunroof is open. They are caused by minor
pressure fluctuations in the vehicle interior.
Change the position of the sliding sunroof
or open a side window slightly to reduce or
eliminate these noises.
Sliding sunroof reversing feature
In the following section, the term "sliding sun-
roof" refers to the panorama roof with power
tilt/sliding panel.
The sliding sunroof is equipped with an auto-
matic reversing feature. If a solid object
blocks or restricts the sliding sunroof during
the closing process, the sliding sunroof opens
again automatically. However, the automatic
reversing feature is only an aid and does not
relieve you of the responsibility of paying
attention when closing the sliding sunroof. G WARNING

to soft, light and thin objects, e.g. small fin-
gers R
over the last 1/6 in (4 mm) of the closing
movement R

when closing the sliding sunroof again man-
ually immediately after automatic reversing
This means that the reversing feature cannot
prevent someone being trapped in these sit-
uations. There is a risk of injury.
Make sure that no body parts are in close
proximity during the closing procedure.
If somebody becomes trapped: R
release the switch immediately, or R
press the switch in any direction during the
automatic closing process

matic lowering. To do so, press the W
switch. The sliding sunroof raises again auto-
matically.

roof after switching off the engine or remov-
ing the SmartKey from the ignition lock. This
function remains active for five minutes or
until you open a front door.
The sliding sunroof cannot be opened if a roof
carrier is installed. In order to allow ventila-
tion of the vehicle interior, you can raise the
sliding sunroof.
If contact is made with a roof carrier approved
by Mercedes-Benz, the sliding sunroof lowers
slightly but remains raised at the rear.
Rain-closing feature
The rain-closing feature is only available for
vehicles with a rain sensor.
When the SmartKey is in position 0 in the
ignition lock or is removed, the sliding sunroof
closes automatically: R
if it starts to rain. R
at extreme outside temperatures. R
after six hours. R
if there is a malfunction in the power sup-
ply.
The panorama roof with power tilt/sliding
panel remains raised at the rear in order to
allow ventilation of the vehicle interior.
If the panorama roof with power tilt/sliding
panel is obstructed while being closed by the
rain-closing feature, it opens again slightly.
The rain-closing feature is then deactivated.
The panorama roof with power tilt/sliding
panel does not close if: R
it is raised at the rear. R
it is blocked. R
no rain is falling on the area of the wind-
shield being monitored by the rain sensor.
If the vehicle is under a bridge or in a car-
port, for example, the field of the sensor
may be covered.
