42 Getting startedDrivingProper use of seat belts

Do not twist the belt when fastening.


Adjust seat belt so that the shoulder
portion is located as close as possible
to the middle of the shoulder (it should
not touch the neck or pass under the
arm).


Position the lap belt as low as possible
on your hips (over hip joint) and not
across the abdomen.


Place the seat backrest in a nearly up-
right position.


Never use a seat belt for more than one
person at a time.


Do not fasten a seat belt around a per-
son and another object at the same
time.


Check your seat belt during travel to
ensure that it is properly positioned.


Ensure that the seat belt is always fit-
ted snugly. You should avoid wearing
bulky clothing, such as winter coats,
when traveling in the vehicle.
Starting the engine
Warning!
G
Do not pass belts over sharp edges. They
could tear.
Do not allow the belt to get caught in the
door or in the seat adjustment mechanism.
This could damage the belt.
Never attempt to make modifications to
seat belts. This could impair the effective-
ness of the belts.
Damaged seat belts or belts that were highly
stressed in an accident must be replaced by
an authorized Mercedes-Benz Center.
Warning!
G
Inhalation of exhaust gas is hazardous to
your health. All exhaust gas contains carbon
monoxide, and inhaling it can cause uncon-
sciousness and lead to death.
Do not run the engine in confined areas
(such as a garage) which are not properly
ventilated. If you think that exhaust gas
fumes are entering the vehicle while driving,
have the cause determined and corrected
immediately. If you must drive under these
conditions, drive with at least one window
fully open.

54 Safety and SecurityOccupant safety
Occupant safetyIn this section you will learn the most im-
portant facts about the restraint systems
of the vehicle.
The restraint systems are:

Seat belts


Emergency tensioning device


Airbags


Child seats


Child seat recognition


Lower anchors and tethers for children
(LATCH)
As independent systems their protective
effects work in conjunction with each oth-
er.The
1
indicator lamp in the instrument
cluster lights up


for about four seconds when you turn
the key in the starter switch to
position1 or press the KEYLESS-GO*
start/stop button once. It then goes
out briefly, lights up again and remains
lit until you start the engine.


for about four seconds when you start
the engine by turning the key or press-
ing the KEYLESS-GO* start/stop but-
ton.The restraint systems are fully operational
if the
1
indicator lamp is not lit when
the engine is running.
A malfunction in the system has been de-
tected, if the 1
indicator lamp:


fails to go out after approximately four
seconds.


does not come on at all.


comes on after the engine was started
or while driving.
For safety reasons, we strongly recom-
mend that you visit an authorized

83 Controls in detail
Locking and unlocking
KEYLESS-GO card*
Specially equipped vehicles come with two
KEYLESS-GO cards. On these vehicles, the
validity of the KEYLESS-GO card is
checked every time you grasp a door
handle.
If the card is valid, your vehicle unlocks

the doors


the trunk lid


the fuel filler flapImportant notes on using KEYLESS-GO


Always carry the KEYLESS-GO card
with you.


Never store the KEYLESS-GO card to-
gether with:

Electronic items such as a cellular
phone or another KEYLESS-GO card


Metallic objects such as coins or
metal foil
Doing so could impair the function of
the KEYLESS-GO system.


Always take an electronic SmartKey
with you in case of a malfunction of the
KEYLESS-GO system.


To lock or unlock the vehicle, the card
must be located outside the vehicle
within approximately 3 ft. (1 m) of a
door or the trunk lid.


In order to start the engine with the
KEYLESS-GO card:

The KEYLESS-GO card must be lo-
cated in the vehicle.


All the doors must be closed.


If you have started the engine with the
KEYLESS-GO start / stop button, you
can only turn it off again with this but-
ton, even if you have put the key in the
starter switch in the meantime.


This does not apply if, after starting, the
selector lever is still in positionP. The
key will then have priority over the card
and the vehicle’s electrical system will
operate according to the position of
the key in the starter switch, even stop-
ping the engine.


If the KEYLESS-GO card is positioned
farther away from the vehicle (e.g. in-
side clothing or briefcase) and can no
longer be recognized by the system,
the vehicle cannot be locked or the en-
gine started via the KEYLESS-GO sys-
tem.
Warning!
G
When leaving the vehicle, always remove the
key from the starter switch, take the
KEYLESS-GO card with you and lock the ve-
hicle. Do not leave children unattended in
the vehicle, or with access to an unlocked
vehicle. Unsupervised use of vehicle equip-
ment may cause an accident and/or serious
personal injury.
!To prevent possible malfunction, avoid
exposing the KEYLESS-GO card to high
levels of electromagnetic radiation.
