34 Getting startedAdjusting
AdjustingSeatsWarning!
G
All seat, head restraint, steering wheel, and
rear view mirror adjustments, as well as fas-
tening of seat belts, must be done before
the vehicle is put into motion.Warning!
G
Do not adjust the driver’s seat while driving.
Adjusting the seat while driving could cause
the driver to lose control of the vehicle.
Never ride in a moving vehicle with the seat
back reclined. Sitting in an excessively re-
clined position can be dangerous. You could
slide under the seat belt in a collision. If you
slide under it, the belt would apply force at
the abdomen or neck. That could cause se-
rious or fatal injuries. The seat back and seat
belts provide the best restraint when the
wearer is in an upright position and belts are
properly positioned on the body.
Your seat must be adjusted so that you can
correctly fasten your seat belt (
page 40).
Never place hands under the seat or near
any moving parts while a seat is being
adjusted.
Warning!
G
When leaving the vehicle, always remove the
SmartKey from the starter switch, take the
SmartKey with KEYLESS-GO* with you, and
lock your vehicle.
The power seats can also be operated with
the driver’s or passenger door open. Do not
leave children unattended in the vehicle, or
with access to an unlocked vehicle. Unsu-
pervised use of vehicle equipment may
cause an accident and/or serious personal
injury.
Warning!
G
Children 12 years old and under must never
ride in the front seat, except in a
Mercedes-Benz authorized BabySmart
TM1
compatible child seat, which operates with
the BabySmart
TM system installed in the ve-
hicle to deactivate the passenger front air-
bag when it is properly installed. Otherwise
they will be struck by the airbag when it in-
flates in a crash. If this happens, serious or
fatal injury will result.
According to accident statistics, children
are safer when properly restrained in the
rear seating positions than in the front
seating positions. Infants and small children
must ride in back seats and be seated in an
appropriate infant or child restraint system,
which is properly secured with the vehicle’s
seat belt or lower anchors, fully in accor-
dance with the child seat manufacturer's
instructions.

Press the KEYLESS GO* start/stop
button once or twice (
page 33).
or

Open the driver’s or passenger door.Seat fore and aft adjustment

Press the switch forward or backward
in the direction of arrow4.
Adjust seat to a comfortable seating
position that still allows you to reach
the accelerator / brake pedal safely.
The position should be as far to the rear
as possible, consistent with ability to
properly operate controls.
A child’s risk of serious or fatal injuries is
significantly increased if the child restraints
are not properly secured in the vehicle and
the child is not properly secured in the child
restraint.
iWhen moving the seat, make sure
there are no items in the footwell or be-
hind the seats. Otherwise you could
damage the seats.
The memory function (
page 116) lets
you store the setting for the seat posi-
tion together with the setting for the
steering wheel and the exterior rear
view mirrors.

41 Getting started
Driving
The seat belt presenter for driver and pas-
senger makes it easier to put on the seat
belt.
1Seat belt presenter
The seat belt presenter slides out when the
corresponding door is closed and the
SmartKey in the starter switch or
KEYLESS-GO* start/stop button are in
position1 or2.
According to accident statistics, children
are safer when properly restrained in the
rear seating positions than in the front seat-
ing positions. Infants and small children
must ride in back seats and be seated in an
appropriate infant or child restraint system,
which is properly secured with the vehicle's
seat belt or lower anchors, fully in accor-
dance with the child seat manufacturer's
instructions.
A child’s risk of serious or fatal injuries is
significantly increased if the child restraints
are not properly secured in the vehicle and
the child is not properly secured in the child
restraint.Warning!
G
Never let more people ride in the vehicle
than there are seat belts available. Make
sure everyone riding in the vehicle is cor-
rectly restrained with a separate seat belt.
Warning!
G
Never ride in a moving vehicle with the seat
backrest reclined. Sitting in an excessively
reclined position can be dangerous. You
could slide under the seat belt in a collision.
If you slide under it, the belt would apply
force at the abdomen or neck. This could
cause serious or even fatal injuries. The seat
backrest and seat belt provide the best re-
straint when the wearer is in an upright po-
sition and the belt is properly positioned on
the body.Warning!
G
Read and observe the additional warning no-
tices printed in the “Safety and Security”
section (
page 62).

58 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 for children (LATCH)
As independent systems, their protective
effects work in conjunction with each oth-
er.The 1 indicator lamp in the instrument
cluster comes on:


for about 4 seconds when you turn the
SmartKey in the starter switch to
position1 or press the KEYLESS-GO*
start/stop button once.


for about 4 seconds when you start the
engine by turning the SmartKey or
pressing the KEYLESS-GO* start/stop
button.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
4 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.
More information can be found in the
“Practical hints” section (
page 318).
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 69).
iThe 1 indicator lamp remains lit if
the SmartKey is turned to position2
and left there or if the KEYLESS-GO*
start/stop button is pressed twice. The
1 indicator lamp will go out when
you start the engine.

59 Safety and Security
Occupant safety
Airbags
Warning!
G
In the event that the 1 indicator lamp
comes on during driving or does not come at
all, the SRS may not be operational. For your
safety, we strongly recommend that you vis-
it an authorized Mercedes-Benz Center im-
mediately to have the system checked;
otherwise the SRS may not be activated
when needed in an accident, which could re-
sult in serious or fatal injury, or it might de-
ploy unexpectedly and unnecessarily which
could also result in injury.
Improper work on the restraint systems, in-
cluding incorrect installation and removal,
can lead to possible injury through an unin-
tended activation of the SRS.
In addition, through improper work there is
a risk of rendering the SRS inoperative or
causing unintended airbag deployment.
Work on the SRS must therefore only be per-
formed by qualified technicians. Contact
your authorized Mercedes-Benz Center.
Warning!
G
Airbags are designed to reduce the potential
for injury resulting from certain frontal im-
pacts (front airbags) or side impacts
(head-thorax airbags and rear side-impact
airbags) which may cause significant inju-
ries. However, no system available today
can totally eliminate injuries and fatalities.
The activation of the SRS temporarily releas-
es a small amount of dust from the airbags.
This dust, however, is neither injurious to
your health, nor does it indicate a fire in the
vehicle. The dust might cause some tempo-
rary breathing difficulty for people with asth-
ma or other breathing trouble. To avoid this,
you may wish to get out of the vehicle as
soon as it is safe to do so. If you have any
breathing difficulty but cannot get out of the
vehicle after the airbag inflates, then get
fresh air by opening a window or door.
Warning!
G
To reduce the risk of injury when the front
airbags inflate, it is very important for the
driver and front passenger to always be in a
properly seated position and to be wearing
seat belts.
For maximum protection in the event of a
collision always be in normal seated position
with your back against the backrest. Fasten
your seat belt and ensure that it is properly
positioned on your body.
Since the airbag inflates with considerable
speed and force, a proper seating and hands
on steering wheel position will help to keep
you at a safe distance from the airbag. Oc-
cupants who are unbelted, out of position or
too close to the airbag can be seriously in-
jured by an airbag as it inflates with great
force in the blink of an eye:

Sit properly belted in an upright position
with your back against the seat back-
rest.
