Important safety notes
GWARNING
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 trunk lid swings upwards when
opened. Therefore, make sure that there is
sufficient clearance above the trunk lid.
!Only close the trunk once the roof is low-
ered completely. Otherwise, you could
damage the roof. If you close the trunk lid before the roof is
lowered completely, the loading aid switch
lights up and a warning tone sounds.
iOpening dimensions of the trunk lid
(
Ypage 608).
iWith the roof open, you can use the load-
ing aid (
Ypage 516) to raise the folded roof
in the trunk to make loading easier. For this
purpose, you can also open the trunk par-
tition.
The trunk partition must be closed again
after loading. It will otherwise not be pos-
sible to close the roof.
You can unlock the trunk lid if the vehicle is
stationary and the roof is completely open or
closed.
Do not leave the SmartKey in the trunk. You
could otherwise lock yourself out.
The trunk lid can be:
Ropened/closed from outside
Ropened and closed automatically from out-
side (vehicles with trunk lid remote closing
feature)
Ropened and closed automatically from
inside (vehicles with trunk lid remote clos-
ing feature)
Ropened, closed or stopped during opera-
tion without the use of your hands (vehicles with KEYLESS-GO and HANDS-FREE
ACCESS)
Rlocked separately
Runlocked with the mechanical key
Ropened with the emergency release button
Trunk lid reversing feature
The trunk lid is equipped with an automatic
reversing feature. It reacts if a solid object
obstructs or restricts the trunk lid during the
closing procedure. The trunk lid opens again
automatically. The automatic reversing func-
tion is only an aid and is not a substitute for
your attentiveness to the trunk lid while it is
closing.

Setting the air vents
Important safety notes
GWARNING
Very hot or very cold air can flow from the air
vents. This could result in burns or frostbite in
the immediate vicinity of the air vents. There
is a risk of injury.
Make sure that all vehicle occupants always
maintain a sufficient distance to the air out-
lets. If necessary, redirect the airflow to
another area of the vehicle interior.
GWARNING
When AIRSCARF is switched on, very hot air
can flow from the vents in the head restraints. This could result in burns in the immediate
vicinity of the air vents. There is a risk of injury.
Reduce the heater output before it becomes
too hot.
In order to ensure the direct flow of fresh air
through the air vents into the vehicle interior,
please observe the following notes:
Rkeep the air inlet grille on the hood and in
the engine compartment on the front-
passenger side free of blockages, such as
ice, snow or leaves.
Rnever cover the air vents or air intake grilles
in the vehicle interior.
iYou can move the adjusters for the air
vents vertically or horizontally to set the
direction of the airflow.
iFor optimal climate control in the vehicle,
open the air vents completely and set the
adjusters to the central position.
Setting the center air vents
XTo open the center air vents: turn the

Do not get into the vehicle again during the
refueling process. Otherwise, electrostatic
charge could build up again.
!Do not use diesel to refuel vehicles with a
gasoline engine. Do not switch on the igni-
tion if you accidentally refuel with the
wrong fuel. Otherwise, the fuel will enter
the fuel system. Even small amounts of the wrong fuel could result in damage to the
fuel system and the engine. Notify a quali-
fied specialist workshop and have the fuel
tank and fuel lines drained completely.
!Overfilling the fuel tank could damage the
fuel system.
!Take care not to spill any fuel on painted
surfaces. You could otherwise damage the
paintwork.
!Use a filter when refueling from a fuel can.
Otherwise, the fuel lines and/or injection
system could be blocked by particles from
the fuel can.
If you overfill the fuel tank, fuel could spray
out when the fuel pump nozzle is removed.
