Steering wheel
Points to remember
Depending on the vehicle equipment, you can
adjust the steering wheel either manually or
electrically*. 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 Adjusting the steering wheel man-

Easy-entry/exit feature*
The easy-entry/exit feature makes getting in
and out of your vehicle easier.
The steering wheel swings upwards when
you:
R remove the key from the ignition lock
R open the driver's door when the key in the
ignition lock is in position 0or 1.
When the key is inserted into the ignition lock
with the driver's door closed, the steering
wheel is automatically moved to the previ-
ously set position. 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 becoming trapped, stop the
adjustment procedure. To halt the procedure:
R press the steering-column adjustment
switch
R press one of the memory function position
buttons
The steering column stops moving immedi-
ately.
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 most recent position of the steering
wheel is stored when you switch off the igni-
tion or when you store a memory position
(Y page 69).
You can activate and deactivate the easy-
entry/exit feature via the on-board computer
(Y page 104). Mirrors

Risk of accident
The exterior mirrors reduce the size of the
image. Objects are actually closer than they
appear. You could misjudge the distance from
vehicles driving behind and cause an acci-
dent, e.g. when changing lane. For this rea-
son, make sure of the actual distance from the
vehicle driving behind by glancing over your
shoulder.
The convex exterior mirrors provide a larger

G
Risk of accident
If incident light from headlamps is prevented
from striking the sensor in the rear-view mir-
ror, for instance, if the safety net is fitted, the
mirror’s automatic anti-dazzle function will
not work.
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 functions*
Storing settings
You can store up to three different settings
using the memory button.
The following settings are stored as a single
memory preset:
R position of the seat, backrest and head
restraint
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

Wearing seat belts
Seat belts are the most effective means of
restraining the movement of vehicle occu-
pants in the event of an accident. This
reduces the risk of vehicle occupants coming
into contact with the vehicle interior. G
Risk of injury
A seat belt which is not worn correctly, or
which has not been engaged in the seat belt
buckle correctly, cannot perform its intended
protective function. Under certain circum-
stances, this could result in severe or even
fatal injuries.
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 70 Seat beltsControls

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
The seat belt does not offer the intended level
of protection unless the backrest is almost
vertical. 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 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. Seat belts

passenger
The 7 seat belt warning lamp in the instru-
ment cluster reminds you that all occupants
should fasten their seat belts. It is either lit
continuously or flashes. Additionally, there
may be a warning tone.
The 7 seat belt warning lamp goes out and
the warning tone ceases as soon as the driver
and front passenger have fastened their seat
belts. For certain countries only: regardless of
whether the driver or the front passenger
already have their seat belt fastened, the
7
seat belt warning lamp lights up for six
seconds after the engine has been started. It
then goes out if both the driver and the front
passenger have fastened their seat belt.
