section (Y page 43). NECK-PRO head restraints/NECK-
PRO luxury head restraints
NECK-PRO head restraints/NECK-PRO luxury
head restraints increase protection of the
driver’s and front-passenger’s head and neck.
In the event of a rear collision of a certain
severity, the NECK-PRO head restraints/
NECK-PRO luxury head restraints on the driv-
er's and front-passenger seats are moved for-
wards and upwards. This provides better
head support. G
Risk of injury
Head restraint covers prevent NECK-PRO
head restraints/NECK-PRO luxury head
restraints from triggering properly. The NECK-
PRO head restraints/NECK-PRO luxury head
restraints can therefore not provide the inten-
ded protection .Do not use head restraint cov-
ers.
If the NECK-PRO head restraints/NECK-PRO
luxury head restraints have been triggered in
an accident, reset the NECK-PRO head
restraints/NECK-PRO luxury head restraints
on the driver's and front-passenger seats
(Y page 41). Otherwise, the additional pro-
tection will not be available in the event of
another rear-end collision. NECK-PRO head
restraints/NECK-PRO luxury head restraints
that have been triggered are moved forwards
and can no longer be adjusted. Resetting triggered NECK-PRO head
restraints
Important safety guidelines Mercedes-Benz recommends that you have
NECK-PRO head restraints/NECK-PRO luxury
head restraints checked at a qualified spe-
cialist workshop, e.g. a Mercedes-Benz
Service Centre, if your vehicle is involved in a
rear-end collision.

Resetting the NECK-PRO head restraints
requires a lot of strength. If you have diffi-
culty resetting the NECK-PRO head

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 in the
event of an accident.
Before starting a journey, make sure that the
seat is properly adjusted and that the back-
rest is almost vertical. G
Risk of injury
Ad irty 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 in the even tofanaccident.
For this reason, check regularly that the seat
belts are not damaged or dirty.
Always have damaged sea tbelts 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. Fastening seat belts
X
Adjust the seat and move the backrest to
an almost vertical position (Y page 84).
X Pull the seat belt smoothly through belt

X Without twisting it, guide the shoulder sec-
tion of the seat belt across the middle of
your shoulder and the lap section across
your hips.
X Engage belt tongue ;in buckle =.
Seat-belt adjustment:ifn ecessary, the
driver's and front-passenger seat belts

X If necessary, adjust the seat belt to the
appropriate height (Y page 44).
X If necessary, pull upwards on the shoulder
section of the seat belt to tighten the belt
across your body.

Belt warning for driver and front
passenger The
7 seat belt warning lamp in the instru-
ment cluster is a reminder for all occupants
to fasten their seat belts .Itmay light up con-
tinuously or flash. In addition, there may be a
warning tone.
The 7 seat belt warning lamp goes out and
the warning tone ceases when the driver and
the fron tpassenger have fastened their seat
belt .Ift he vehicle is stationary and a door is
opened, the 7seat belt warning lamp
goes out and the warning tone ceases.
For certain countries only: regardless of
whether the driver or the front passenger
have fastened their seat belts, the 7seat
belt warning lamp lights up for six seconds
after the engine is started. It then goes out if
the driver and the front passenger have fas-
tened their seat belts.
i For more information on the 7seat
belt warning lamp, see "Indicator and warn-
ing lamps in the instrumentc luster, seat
belt" (Y page 239).
Rear seat belt status indicator The rear-compartmen
tseat belt status indi-
cator tells you if the rear passengers have
their seat belts fastened.
The rear-compartment seat belt status indi-
cator indicates the rear seat on which the belt
is fastened. 44

Problems with the steering wheel heat-
ing
If the steering wheel heating indicator lamp
on the lower left lever of the steering column
is flashing, the steering wheel heating has
switched off automatically. The vehicle's
electrical system voltage is too low because
too many electrical consumers are switched
on.
X
Switch off electrical consumers which you
do not need, such as the rear window heat-
ing or interior lighting.
Once the battery is sufficiently charged, the
steering wheel heating will switch back on
automatically. EASY-ENTRY/EXIT system
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 someone becoming trap-
ped, stop the adjustment procedure. To halt
the procedure:
R move the switch for steering wheel adjust-
ment in the opposite direction to that in
which the steering wheel is moving.
R press one of the memory function position
buttons.
Never leave children unsupervised in the vehi-
cle. They could open the driver's door and
thereby unintentionally activate the EASY-
ENTRY/EXIT feature and become trapped.
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 and KEYLESS-GO is
in position 1
R open the driver's door and the key is in
position 0or 1in the ignition lock i
The steering wheel only moves upwards if
it has not already reached the upper end
stop.
If you insert the key into the ignition lock with
the driver's door closed, the steering wheel is
automatically moved to the previously set
position.
The last position of the steering wheel is
stored after each manual setting or when you
store the setting with the memory function
(Y page 95).
You can activate and deactivate the EASY-
ENTRY/EXIT feature in the on-board com-
puter (Y page 211).
i If the crash-responsive EASY-EXIT feature
is triggered in an accident, the steering col-
umn will move upwards when the driver's
door is opened. This occurs irrespective of
the position of the key 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 after an accident if the
EASY-EXIT/ENTRY feature is activated in
the on-board computer. Mirrors

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 roller sun-
blind is extended, the mirror's automatic anti-
dazzle function will not operate.
Incident light could then blind you. This may
distract you from the traffic conditions and,
as a result, you may cause an accident .Inthis
case, adjust the rear-view mirror manually.
The rear-view mirror and the exterior mirror
on the driver's side automatically go into anti-
dazzle mode if the ignition is switched on and
incident light from headlamps strikes the sen-
sor in the rear-view mirror.
The mirrors do not go into anti-dazzle mode if
reverse gear is engaged or the interior lighting
is switched on. Parking position for the exterior mir-

ferent people.

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. They could otherwise become
trapped when adjusting the seat or the steer-
ing wheel. G
Risk of accident
Only use the memory function on the driver's

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
