Warning!
G
When leaving the vehicle, always remove the 
SmartKey from the starter switch and lock 
the vehicle. Do not leave children unattend-
ed in the vehicle, or with access to an un-
locked vehicle. Children could release the 
parking brake and/or move the gear selec-
tor lever from positionP, either of which 
could result in an accident and/or serious 
injury.
Warning!
G
Getting out of your vehicle with the gear se-
lector lever not fully engaged in positionP is 
dangerous. Also, when parked on an incline, 
positionP alone may not prevent your vehi-
cle from moving, possibly hitting people or 
objects.
Always set the parking brake in addition to 
shifting to positionP (manual transmission: 
first or reverse gear).
When parked on an incline, turn front wheels 
towards the road curb.

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 indicator lamp in the instrument 
cluster (
page 22) comes on:
for about four seconds when you turn 
the SmartKey in the starter switch to 
position1.
for about four seconds when you start 
the engine by turning the SmartKey.The 1 indicator 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 indicator lamp:
fails to extinguish 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 
Mercedes-Benz Center immediately to 
have the system checked.
For more information see “Practical hints” 
section (
page 262).
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).
iThe 1 indicator lamp remains lit if 
the SmartKey is turned to position2 
and left there. The indicator lamp will 
go out when you start the engine.

61 Safety and Security
Occupant safety
When you sell your vehicle we strongly 
urge you to give notice to the subsequent 
owner that it is equipped with an SRS by 
alerting them to the applicable section in 
the Operator’s Manual.
Front airbags
Driver and passenger airbags are de-
ployed: 
in the event of a frontal impact
if impact exceeds a preset deployment 
threshold
independently of the side impact air-
bags
The airbags will not deploy in impacts 
which do not exceed the system’s deploy-
ment thresholds. You will then be protect-
ed by the fastened seat belts.The front passenger airbag will only be de-
ployed if:
the front passenger seat is occupied

in the center console is not lit 
(page 67)
the impact exceeds a preset deploy-
ment threshold.
1Driver airbag
2Passenger airbagSide impact airbags, window curtain 
airbags
The side impact airbags and window cur-
tain airbags are deployed:
on the impacted side of the vehicle
in impacts exceeding a preset deploy-
ment threshold
independently of the front airbags
The side impact airbags and window cur-
tain airbags are not deployed in impacts 
which do not exceed the system’s deploy-
ment threshold.!Do not place objects heavier than 
20 lbs (9kg) on the front passenger 
seat. This could cause the front or side 
impact airbag on the front passenger 
side to deploy in a crash which exceeds 
the system’s deployment threshold.

62 Safety and SecurityOccupant safetyThe front passenger side impact airbag will 
only deploy if the system senses that the 
front passenger seat is occupied.
1Window curtain airbag
2Side impact airbagsSeat belts
When the engine is started, the seat belt 
non-usage warning lamp< illuminates 
to remind you and your passengers to fas-
ten your seat belts. If the driver’s seat belt 
is not fastened before the engine is 
started, the seat belt non-usage warning lamp< illuminates and a warning 
chime sounds for approximately 
six seconds when the engine is started.
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.
For more information on seat belts see 
“Fastening the seat belt” (
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.
