• Sit properly belted in an upright position with
your back against the backrest.• Adjust the driver seat as far as possible
rearward, still permitting proper operation of
vehicle controls. The distance from the center
of the driver’s breastbone to the center of the
airbag cover on the steering wheel must be at
least ten inches (25 cm) or more. You should be
able to accomplish this by a combination of
adjustments to the seat and steering wheel. If
you have any problems, please see your
authorized Mercedes-Benz Center.• Do not lean with your head or chest close to the
steering wheel or dashboard.• Keep hands on the outside of steering wheel
rim. Placing hands and arms inside the rim
can increase the risk and potential severity of
hand/arm injury when the driver front airbag
inflates.• Adjust the front passenger seat as far as
possible rearward from the dashboard when
the seat is occupied.
• Occupants, especially children, should never
lean their heads in the area of the door where
the side airbag inflates. This could result in
serious injuries or death should the airbag be
triggered. Always sit upright, properly use the
seat belts, and appropriate size infant or child
restraint system.• Children 12 years old and under must never
ride in the front seat, except in a
Mercedes-Benz authorized BabySmart
TM
compatible child seat, which operates with the
BabySmart
TM system installed in the vehicle to
deactivate the passenger front airbag when it
is properly installed. Otherwise they will be
struck by the airbag when it inflates in a crash.
If this happens, serious or fatal injury can
result.
Failure to follow these instructions can result in
severe or fatal injuries to you or other occupants.

Wa r n i n g !
Accident research shows that the safest place for
children in an automobile is in the rear seat.
Should you choose to place a child 12 years old or
under in the front passenger seat of your vehicle,
you must properly use a BabySmart
TM child
restraint which will turn off the passenger side
front airbag. BabySmart
TM will not, however, turn
off the passenger’s side impact airbag.
It should be noted however that there is a
possibility for a side airbag related injury if
occupants, especially children, are not properly
seated or restrained when next to a side airbag
which needs to deploy rapidly in a side impact in
order to do its job.To help avoid the possibility of injury, please follow
these guidelines: (1) occupants, especially
children, should never place their bodies or lean
their heads in the area of the door where the side
airbag inflates. This could result in serious
injuries or death should the side airbag be
activated; (2) always sit upright, properly use the
seat belts and use an appropriately sized infant or
child restraint system for all children 12 years old
or under; and (3) always wear seat belts properly.
Wa r n i n g !
• Damaged seat belts or belts that were highly
stressed in an accident must be replaced and
their anchoring points must also be checked.
Use only belts installed or supplied by an
authorized Mercedes-Benz Center.• Do not pass belts over sharp edges.• Do not make any modification that could
change the effectiveness of the belts.• Ai rba gs an d E T Ds are d esi gned to fun c tion on a
one-time-only basis. An airbag or Emergency
tensioning device (ETD) that was activated
must be replaced.

When you sell the vehicle we strongly urge you to give
notice to the subsequent owner that it is equipped with
an SRS by alerting him to the applicable section in the
Operator’s Manual.
• No modifications of any kind may be made to
any components or wiring of the SRS. This
includes changing or removing any component
or part of the SRS, the installation of additional
trim material, badges etc. over the steering
wheel hub, front passenger airbag cover, or
front door trim panels, and installation of
additional electrical/electronic equipment on
or near SRS components and wiring. Keep area
between airbags and occupants free of objects
(e.g. packages, purses, umbrellas, etc.).• An airbag system component within the
steering wheel gets hot after the airbag has
inflated. Do not touch.• Improper work on the system, including
incorrect installation and removal, can lead to
possible injury through an unintended
activation of the SRS .• In addition, through improper work there is
the risk of rendering the SRS inoperative or
causing unintended airbag deployment. Work
on the SRS must therefore only be performed
by an authorized Mercedes-Benz Center.
• For your protection and the protection of
others, when scrapping the airbag unit or
Emergency tensioning device, our safety
instructions must be followed. These
instructions are available at your authorized
Mercedes-Benz Center.• Given the considerable deployment speed and
the textile structure of the airbags, there is the
possibility of abrasions or other injuries
resulting from airbag deployment.

Children 12 years old and under must never ride in
the front seat, except in a Mercedes-Benz
authorized BabySmart
TM compatible child seat,
which operates with the BabySmart
TM system
installed in the vehicle to deactivate the passenger
front airbag when it is properly installed.
Otherwise they will be struck by the airbag when it
inflates in a crash. If this happens, serious or fatal
injury can 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
accordance with the child seat manufacturer’s
instructions.Infants and small children should never share a
seat belt with another occupant. During an
accident, they could be crushed between the
occupant and seat belt.
Children too big for child restraint systems must
ride in back seats using regular seat belts. Position
shoulder belt across chest and shoulder, not face or
neck. A booster seat may be necessary to achieve
proper belt positioning for children from 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 accident and/or serious personal injury.

Supplemental restraint system (SRS) indicator lamp
The operational readiness of the airbag
system is verified by the indicator lamp
“SRS” in the instrument cluster when
turning the electronic key in steering lock to position 1
or 2. If no malfunction is detected, the lamp will go out
after approximately 4 seconds; after the lamp goes out,
the system continues to monitor the components and
circuitry of the airbag system and will indicate a
malfunction by coming on again.
See page 61 for notes on airbags, see page 60 for belt
tensioners and page 69 for infant and child seat
restraint.Fuel reserve and fuel cap placement warning
When the warning lamp (1) comes on after starting the
engine, or if it comes on while driving, it indicates that
the fuel level is down to the reserve quantity of
approximately 2.1 gal (8 liters).
The warning lamp blinks when the fuel cap is not
closed, or a fuel system leak has been detected.
Retighten cap and see if lamp goes out after restart and
next OBD selfcheck.
If the warning lamp continues to blink after closing the
fuel cap correctly, have the fuel system checked at your
authorized Mercedes-Benz Center as soon as possible.
Leaving the engine running and the fuel cap open can
also cause the “CHECK ENGINE” lamp to illuminate, see
page 224.
Wa r n i n g !
In the event a malfunction of the “SRS” is indicated
as outlined above, the “SRS” may not be
operational. For your safety, we strongly
recommend that you visit an authorized
Mercedes-Benz Center immediately to have the
system checked; otherwise the “SRS” may not be
activated when needed in an accident, which could
result in serious or fatal injury, or it might deploy
unexpectedly and unnecessarily which could also
result in injury.SRS
