effort is necessary to stop or steer the vehi-
cle.

bustible materials such as grass, hay or
leaves can come into contact with the hot

56 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
warning lamp in the instrument
cluster lights up:


for about 4 seconds when you turn the
key in the starter switch to position1.


for about 4 seconds when you start the
engine by turning the key.The warning lamp goes out shortly after
you start the engine. This shows that the
restraint systems are operational.
A malfunction in the system has been de-
tected if the
1
warning lamp:


fails to extinguish after approximately
4seconds.


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
Mercedes-Benz Center immediately to
have the system checked.
More information can be found in the
“Practical hints” section (
page 248).
iFor information on infants and children
traveling with you in the vehicle and re-
straint systems for infants and chil-
dren, see “Children in the vehicle”
(page 65).

is turned to position2 and left there.
The warning lamp will go out when you

in the instrument cluster lights up and a
warning sounds for a short time when you
turn the key in the starter switch to
position2 and the driver‘s seat belt is not
fastened.After starting the engine the seat belt non-
usage warning lamp blinks for a brief peri-
od to remind the driver and passengers to
fasten the seat belts.
The use of seat belts and infant and child
restraint systems is required by law in
most states and all Canadian provinces.
Even where this is not the case, all vehicle
occupants should have their seat belts fas-
tened whenever the vehicle is in motion.
Information on fastening seat belts is
found in the “Getting started” section
(
page 41).iFor information on infants and children
traveling with you in the vehicle and re-
straint systems for infants and chil-
dren, see “Children in the vehicle”
(page 65).
Warning!
G
Always fasten your seat belt before driving
off. Always make sure your passengers are
properly restrained, even those sitting in the
rear and pregnant women.
Failure to wear and properly fasten and po-
sition your seat belt greatly increases your
risk of injuries and their likely severity in an
accident. You and your passengers should
always wear seat belts.
If you are ever in an accident, your injuries
can be considerably more severe without
your seat belt properly buckled. Without
your seat belt buckled, you are much more
likely to hit the interior of the vehicle or be
ejected from it. You can be seriously injured
or killed.
In the same crash, the possibility of injury or
death is lessened if you are properly wearing
your seat belt. Airbags can only protect as
they are designed if the occupants are prop-
erly wearing their seat belts.
