Points to remember
G
Risk of injury
The electrically adjustable steering wheel can
be adjusted when the key is removed from the
ignition lock. Therefore, do not leave children
unsupervised in the vehicle as they could
become trapped as the steering wheel is
adjusted. G
Risk of accident
Only adjust the steering wheel when the vehi-
cle is stationary and do not pull away until the
steering wheel adjustment mechanism is
locked in position. Otherwise, you might drive
without the steering wheel adjustment mech-
anism being locked in position and be distrac-
ted from road and traffic conditions by an
unexpected movement of the steering wheel
and cause an accident.
However, the steerability of the vehicle is not
affected.
When you adjust the steering wheel, make
sure that:
R the steering wheel can be reached with
your arms slightly bent
R you can move your legs freely
R you can see all the displays in the instru-
ment cluster clearly Steering wheel

i The steering wheel heating is switched off
automatically after about 24 minutes. Easy-entry/exit feature
The EASY-ENTRY/EXIT feature makes getting
in and out of your vehicle easier. The steering wheel tilts upwards and the driv-
er's seat slides back if you:
R remove the key from the ignition lock
R open the driver's door when the key is in
the ignition lock or in position 1
i The steering wheel only moves upwards
if it has not already reached the upper end
stop. The driver's seat only moves back-
wards if it is not already in the rearmost
position.
If you insert the key into the ignition with the
driver's door closed, the position of the steer-
ing wheel and the driver's seat will be
changed to the last selected position.
i The adjustment procedure stops when
you begin driving. G
Risk of injury
Make sure that nobody can become trapped
when you activate the EASY-ENTRY/EXIT fea-
ture.
If there is a risk of entrapment by the steering
column, move the steering wheel adjustment
lever or press the position button of the mem-
ory function.
If there is a risk of entrapment by the seat, you
can also cancel the adjustment procedure by
moving the seat adjustment switch. The steer-
ing column and driver's seat* stop moving
immediately.
Never leave children unsupervised in the vehi-
cle. They could open the driver's door and,
thereby, unintentionally activate the EASY-
ENTRY feature and become trapped.
The last driving position of the steering wheel
or the seat is saved if:
R the ignition is switched off
or
R a memory position is stored.
You can activate and deactivate the EASY-
ENTRY/EXIT feature using COMAND
(Y page 165). 188

The mirrors do not go into anti-dazzle mode if
reverse gear is engaged or the interior lighting
is switched on. G
Risk of accident
If the incident light from headlamps cannot
strike the sensor in the rear-view mirror, for
instance, when the rear window blind* is
extended, the mirror's automatic anti-dazzle
function will not operate.
Incident light could then dazzle you. This may
distract you from the traffic conditions, and
you may, thereby, cause an accident. In this
case, adjust the rear-view mirror manually. Memory function
Storing settings
Using the memory button you can store up to
three different settings, e. g. for three differ-
ent people.
The following settings are stored as a single
memory preset:
R seat, backrest, head restraint position and
contour of the backrest in the lumbar
region
R active multicontour seat*: activated/deac-
tivated
R multicontour seat*: the side bolsters of the
seat cushion and the backrest as well as
the contour of the backrest in the lumbar
and shoulder regions
R driver's side: steering wheel position
R driver's side: position of the exterior mir-
rors on the driver's and front-passenger
sides G
Risk of injury
The memory function can still be used when
the key has been removed. For this reason,
children should never be left unsupervised in
the vehicle. Otherwise, they could become
trapped when moving the seat or the steering
wheel. G
Risk of accident
Only use the memory function on the driver’s
side when the vehicle is stationary. Other-
wise, you could be distracted from the traffic
conditions by the steering wheel and seat
moving of their own accord, and as a result
cause an accident. X
Adjust the seat (Y page 183).
X On the driver's side, also adjust the steer-
ing wheel ( Ypage 187) and the mirrors
(Y page 189).

Make sure that all occupants – in particular,
pregnant women – wear their seat belt cor-
rectly at all times.
R The seat belt must pass closely over your
body and must not be twisted. Therefore,
you should avoid wearing bulky clothing
(e.g. a winter coat). The shoulder belt sec-
tion must be routed across the middle of
your shoulder – on no account across your
neck or under your arm – and pulled tight
against your upper body. The lap belt must
always pass across your lap as low down as
possible, i.e. over your hip joints – not
across your abdomen. If necessary, push
down the belt strap slightly and then
retighten it in the roll-up direction.
R Do not route the belt strap across sharp or
fragile objects, especially if these are loca-
ted on or in your clothing, e.g. spectacles,
pens, keys, etc. The seat belt strap could
be damaged and tear in an accident, and
you or other vehicle occupants could be
injured.
R Only one person should use each seat belt
at any one time. Children must never travel
sitting on the lap of other occupants. It
would not be possible to restrain the child
in the event of a sudden change in direc-
tion, braking or an accident. This could
result in severe or even fatal injuries to the
child and other occupants.
R Persons less than 1.50 m tall cannot wear
the seat belts correctly. For this reason,
secure persons less than 1.50 m tall in spe-
cially designed, suitable restraint systems.
R Children less than 1.50 m tall or under
12 years of age cannot wear the seat belts
properly. Therefore, they always should be
secured in a suitable child restraint system
on a suitable vehicle seat. You can find
more information under "Children in the
vehicle" in the "Safety" section of the Own-
er's Manual. Follow the manufacturer's installation instructions when fitting the
child restraint system.
R Do not secure any objects with a seat belt
if the seat belt is also being used by one of
the vehicle's occupants. G
Risk of injury
If the backrest is not almost vertical, the seat
belt does not offer the intended level of pro-
tection. Under certain circumstances, this
could cause severe or even fatal injuries.
Before starting a journey, make sure that the
seat is properly adjusted and that the back-
rest is almost vertical. G
Risk of injury
A dirty or damaged seat belt or a seat belt that
has been subjected to a load in an accident
or which has been modified no longer offers
the intended level of protection. Under certain
circumstances, this could cause severe or
even fatal injuries.
For this reason, check regularly that the seat
belts are not damaged or dirty.
Always have damaged seat belts or seat belts
that have been subjected to a load in an acci-
dent replaced at a qualified specialist work-
shop. Consult a qualified specialist workshop
which has the necessary specialist knowledge
and tools to carry out the work required.
Mercedes-Benz recommends that you use a
Mercedes-Benz Service Centre for this pur-
pose.
For safety reasons, Mercedes-Benz recom-
mends that you only use seat belts which have
been approved by Mercedes-Benz for your
vehicle. 192

General notes
G
Risk of injury
Make sure that nobody can become trapped
when closing the sliding sunroof. If there is a
risk of entrapment, release the switch and
push it briefly in any direction to stop the slid-
ing sunroof. G
Risk of injury
Children could injure themselves if they oper-
ate the sliding sunroof.
Never leave children unsupervised in the vehi-
cle. Always take the key with you when leaving
the vehicle, even if you are only leaving it for
a short time. G
Risk of injury
The glass in the panorama sunroof could
break in an accident. If you are not wearing a
seat belt, there is a risk that you could be
thrown through the opening in the event of the
vehicle overturning. Therefore, always wear a
seat belt to reduce the risk of injuries.
! Only open the panorama sliding sunroof
if it is free of snow and ice. Otherwise, mal-
functions may occur.
Do not allow anything to protrude from the
sliding sunroof. The seals could otherwise
be damaged. i
When the sliding sunroof is open, apart
from the normal airflow noises resonance
noises may also occur. 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.
