!
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.
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. The noise will be
reduced or eliminated. Sliding sunroof reversing feature
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
The reversing feature does not react:
R 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 during resetting
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 during automatic operation, push the
switch briefly in any direction

Important safety notes G
WARNING
When the EASY-ENTRY/EXIT feature adjusts
the steering wheel, you and other vehicle
occupants – particularly children – could
become trapped. There is a risk of injury.
While the EASY-ENTRY/EXIT feature is mak-
ing adjustments, make sure that no one has
any body parts in the sweep of the steering
wheel.
Move the steering wheel adjustment lever if
there is a risk of entrapment by the steering
wheel. The adjustment process is stopped.
Press one of the memory function position
buttons. This function is only available on
vehicles with memory function. G
WARNING
If children activate the EASY-ENTRY/EXIT fea- ture, they can become trapped, particularly
when unattended. There is a risk of injury.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle. Never leave children unsupervised in the vehicle. G
WARNING
If you drive off while the EASY-ENTRY/EXIT
feature is making adjustments, you could lose
control of the vehicle. There is a risk of an
accident.
Always wait until the adjustment process is
complete before driving off. The EASY-ENTRY/EXIT feature makes getting
in and out of your vehicle easier.
You can activate and deactivate the EASY-
ENTRY/EXIT feature in the on-board com-
puter (Y page 287).
Position of the steering wheel when the
EASY-ENTRY/EXIT feature is active The steering wheel swings upwards when
you:
R remove the SmartKey from the ignition lock
R open the driver's door with KEYLESS-GO in
position 1
R open the driver's door and the SmartKey is
in position 0or 1in the ignition lock
i The steering wheel only moves upwards if
it has not already reached the upper stop.
Position of the steering wheel for driv-
ing The steering wheel is moved to the last selec-
ted position when:
R the driver's door is closed
R you insert the SmartKey into the ignition
lock
or
R you press the Start/Stop button once on
vehicles with KEYLESS-GO
When you close the driver's door with the
ignition switched on, the steering wheel is
also automatically moved to the previously
set position.
The last position of the steering wheel is
stored when you switch off the ignition or Steering wheel

function (Y page 124).
Crash-responsive EASY-EXIT feature If the crash-responsive EASY-EXIT feature is
triggered in an accident, the steering column
will move upwards when the driver's door is
opened. This occurs irrespective of the posi-
tion of the SmartKey in the ignition lock. This makes it easier to exit the vehicle and rescue the occupants.
The crash-responsive EASY-EXIT feature is
only operational if the EASY-EXIT/ENTRY fea-
ture is activated in the on-board computer
(Y page 287). Mirrors

WARNING
The exterior mirror on the front-passenger
side reduces the size of the image. Visible
objects are actually closer than they appear.
This means that you could misjudge the dis-
tance from road users traveling behind, e.g.
when changing lane. There is a risk of an acci-
dent. For this reason, always make sure of the
actual distance from the road users traveling
behind by glancing over your shoulder.

General notes
For reasons of safety, Mercedes-Benz recom- mends that you drive with the lights switchedon even during the daytime. In some coun-
tries, operation of the headlamps varies due
to legal requirements and self-imposed obli-
gations. Driving abroad
Conversion to symmetrical low beam Switch the headlamps to symmetrical low
beam in countries in which traffic drives on
the opposite side of the road from the country
where the vehicle is registered. This prevents glare to oncoming traffic. When using sym-
metrical lights, the edge of the road is not lit
as widely and as far ahead as normal.
Have the headlamps converted at a qualified
specialist workshop as close to the border as
possible before driving in these countries.
Conversion to asymmetrical low beam
after returning Have the headlamps converted back to asym-
metrical low-beam headlamps at a qualified
specialist workshop as soon as possible after crossing the border again. Setting the exterior lighting

switch to 0058, the manual settings take
precedence over the daytime running lamps.
USA only:
The daytime running lamps improve the visi-
bility of your vehicle during the day. To do this,
the daytime running lamps function must be
switched on using the on-board computer
(Y page 285).
If the engine is running and you turn the light
switch to 0060or0058, the manual settings
take precedence over the daytime running
