70 Safety and SecurityOccupant safetyWarning!
G
Damaged seat belts or belts that were highly
stressed in an accident must be replaced
and their anchoring points must also be
checked.
Only use seat belts which have been
approved by Mercedes-Benz.
Do not make any modifications to the seat
belts. This can lead to unintended activation
of the ETDs or to failure.
Do not bleach or dye seat belts as this may
severely weaken them. In a crash, they may
not be able to provide adequate protection.
Have all work carried out only by qualified
technicians. Contact an authorized
Mercedes-Benz Center.
Warning!
G
USE SEAT BELTS PROPERLY
Each occupant should wear his or her
seat belt at all times, because seat belts
help reduce the likelihood and potential
severity of injuries in accidents, includ-
ing rollovers. The integrated restraint
system includes SRS (driver air bag,
passenger front air bag, front side im-
pact air bags, rear side impact
air bags*, head protection window cur-
tain air bags for side windows), ETD
(seat belt emergency tensioning device),
and front seat knee bolsters.
The system is designed to enhance the
protection offered to properly belted oc-
cupants in certain frontal (front air bags
and ETD) and side (front side impact
air bags, rear side impact air bags*, win-
dow curtain air bags and ETD) impacts
which exceed preset deployment
thresholds.
Seat belts can only work when used
properly. Never wear seat belts in any
other way than as described in this sec-
tion, as that could result in serious inju-
ries in case of an accident.
Never wear the shoulder belt under your
arm, against your neck or off your shoul-
der. In a crash, your body would move
too far forward. That would increase the
chance of head and neck injuries. The
belt would also apply too much force to
the ribs or abdomen, which could se-
verely injure internal organs such as
your liver or spleen.
Never wear belts over rigid or breakable
objects in or on your clothing, such as
eyeglasses, pens, keys etc., as these
might cause injuries.
Position the lap belt as low as possible
on your hips and not across the abdo-
men. If the belt is positioned across your
abdomen, it could cause serious injuries
in a crash.
77 Safety and Security
Occupant safety
Occupant Classification System
The Occupant Classification System (OCS)
automatically turns the front passenger
front air bag on or off based on the classi-
fied occupant weight category determined
by weight sensor readings from the front
passenger seat.
Occupants must sit properly belted in a
nearly upright position with their back
against the seat backrest and feet on the
floor to be correctly classified. If the occu-
pant’s weight is transferred to another
object in the vehicle (e.g. by leaning on
armrests), the OCS may not be able to
properly approximate the occupant’s
weight category.Both driver and the front passenger should
always use the 56indicator lamp
as an indication of whether or not the front
passenger is properly positioned.
Children too big for a toddler restraint must
ride in seats using regular seat belts. Posi-
tion shoulder belt across chest and shoul-
der, not face or neck. A booster seat may be
necessary to achieve proper belt positioning
for children from 18.6 kg (41 lbs) until they
reach a height where a lap/shoulder belt fits
properly without a booster.
When the child restraint is not in use,
remove it from the vehicle or secure it with
the seat belt to prevent the child restraint
from becoming a projectile in the event of
an accident.
Do not leave children unattended in the
vehicle, even if the children are secured in a
child restraint system. Unsupervised
children in a child restraint system may use
vehicle equipment and may cause an acci-
dent and/or serious personal injury.
iThe system does not deactivate the
front passenger side impact air bag,
the window curtain air bag and the
emergency tensioning device.
iIf your seat, including your trim cover
and cushion needs to be serviced in
any way, take the vehicle to your
authorized Mercedes-Benz Center.
Only seat accessories approved by
Mercedes-Benz may be used. Warning!
G
If the 56indicator lamp illuminates
when an adult or someone larger than a
small individual is in the front passenger
seat, have the front passenger re-position
himself or herself in the seat until the
56indicator lamp goes out.

sages (

Auto-dimming rear view mirrors*
The reflection brightness of the exterior
rear view mirror on the driver’s side and
the interior rear view mirror will respond
automatically to glare when
the ignition is switched on
and
incoming light from headlamps falls on
the sensor in the interior rear view
mirror.
The rear view mirror will not react if
reverse gearR is engaged
the interior lighting is turned on
Warning!
G
The auto-dimming function does not react if
incoming light is not aimed directly at
sensors in the interior rear view mirror.
The interior rear view mirror and the exterior
rear view mirror on the driver’s side do not
react, for example, if the rear window
sunshade* is in raised position.
Glare can endanger you and others.Warning!
G
In case of an accident, liquid electrolyte may
escape from the mirror housing if the mirror
glass breaks.
Electrolyte has an irritating effect. Do not
allow the liquid to come into contact with
eyes, skin, clothing, or respiratory system.
In case it does, immediately flush affected
area with water, and seek medical help if
necessary.
!Electrolyte drops coming into contact
with the vehicle paint finish can be
completely removed only while in the
liquid state and by applying plenty of
water.Warning!

Exercise care when using the passen-
ger-side exterior rear view mirror. The mirror
surface is convex (outwardly curved surface
for a wider field of view). Objects in mirror
are closer than they appear. Check your
interior rear view mirror or glance over your
shoulder before changing lanes.
