Important safety notes
GWARNING
Parts of the body could become trapped
between the roller sunblind and frame or slid-
ing sunroof during automatic opening or clos-
ing. There is a risk of injury.
When opening or closing, make sure that no
body parts are in the sweep of the roller sun-
blind.
If somebody becomes trapped:

The roller sunblinds are equipped with an auto-
matic reversing feature. If a solid object blocks
or restricts a roller sunblind during the closing
process, the roller sunblind opens again auto-
matically. The automatic reversing feature is
only an aid and is not a substitute for your atten-
tion when closing the roller sunblinds.
GWARNING
The reversing feature does not react in par-
ticular to soft, light and thin objects, e.g. small
fingers. This means that the reversing feature
cannot prevent someone being trapped in
these situations. There is a risk of injury.
When closing the roller sunblind, make sure
that no body parts are in the sweep area.
If somebody becomes trapped:
Rrelease the switch immediately, or

Pulling away
General notes
GWARNING
If the engine speed is above the idling speed
and you engage transmission position Dor R,
the vehicle could pull away suddenly. There is
a risk of an accident.
When engaging transmission position Dor R,
always firmly depress the brake pedal and do not simultaneously accelerate.
Depress the accelerator carefully when pulling
away.
The vehicle locks centrally once you have pulled
away. The locking knobs in the doors drop down.
You can open the doors from the inside at any
time.
You can also deactivate the automatic locking
feature (
Ypage 87).
It is only possible to shift the transmission from
position Pto the desired position if you depress
the brake pedal. Only then is the parking lock
released.
If you do not depress the brake pedal, the
DIRECT SELECT lever can still be moved but the
parking lock remains engaged.
iUpshifts take place at higher engine speeds
after a cold start. This helps the catalytic con-
verter to reach its operating temperature
more quickly.

electric parking brake (
Ypage 191).
Hill start assist
Hill start assist helps you when pulling away for-
wards or in reverse on an uphill gradient. It holds
the vehicle for a short time after you have
removed your foot from the brake pedal. This
gives you enough time to move your foot from
the brake pedal to the accelerator pedal and to
depress it before the vehicle begins to roll.
GWARNING
After a short time, hill start assist will no lon-
ger brake your vehicle and it could roll away.
There is a risk of an accident and injury.

Important safety notes
GWAR NING
When you load the roof, the center of gravity
of the veh iclerises and the driving character-
istics change. Ifyou exceed the maximum roof
load, the driving characteristics, as wellas
steering and braking, will begreatly impaired.
There isa risk of an acc ident.
Never exceed the maximum roof load and
adjust your driving style.
You willfind information on the maximum roof
load inthe "Technical data" section
(
Ypage 433).
!Mercedes-Benz recommends that you only
use roof carriers that have been tested and
approved for Mercedes-Benz veh icles. This
helps to avoid damage to the veh icle.
Position the load on the roof carrier insuch a
way that the veh icle willnot sustain damage
even when it is inmotion.
Ensure that, dependin g on the vehicle's
equipm ent, you can raise the panorama roof
wit h power tilt/ sliding panel fully and open
the trunk lidfully when the roof carrier is
installed.
!To avoid damaging or scratching the covers,
do not use metallic or hard objects to open
them.
An incorrectly secured roof carrier or roof load
may become detached from the vehicle. You
must therefore ensure that you observe the roof carrier manufacturer's installation instructions.
