Important safety notes
G WARNING
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. Exhaust
gases can enter the vehicle interior if the
trunk lid is open when the engine is running,
especially if the vehicle is in motion. There is a
risk of poisoning.
Always switch off the engine before opening
the trunk lid. Never drive with the trunk lid
open.
! The trunk lid swings upwards when opened.
Therefore, make sure that there is sufficient
clearance above the trunk lid. The opening dimensions of the trunk lid can be
found in the "Vehicle data" section
( Y
page 336).
You should preferably place luggage or loads in
the trunk. Observe the loading guidelines
( Y
page 251).
Do not leave the SmartKey in the trunk. You

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 feature
is only an aid and is not a substitute for your
attentiveness to the trunk lid while it is closing.
G WARNING
The reversing feature does not react: R
to soft, light and thin objects, e.g. small fin-
gers R
over the last 1/3 in (8 mm) of the closing
movement
This means that the reversing feature cannot
prevent someone being trapped in these sit-

gered in an accident, the steering column will
move upwards when the driver's door is opened.
This occurs irrespective of the position of the

Exterior lighting
General notes For reasons of safety, Mercedes-Benz recom-
mends that you drive with the lights switched on
even during the daytime. Therefore, your vehicle
is equipped with special daytime running lamps.
In some countries, operation of the headlamps
varies due to legal requirements and self-
imposed obligations.
If you wish to drive during the daytime without
lights, switch off the daytime running lamps
function in the on-board computer
( Y
