Adjust the driver’s seat as far as possi-
ble rearward, still permitting proper op-
eration of vehicle controls. The distance
from the center of the driver’s breast-
bone to the center of the air bag cover
on the steering wheel must be at least
10 in (25 cm) or more. You should be
able to accomplish this by a combina-
tion of adjustments to the seat and
steering wheel. If you have any prob-
lems, please see an authorized
Mercedes-Benz Center.
Do not lean with your head or chest
close to the steering wheel or dash-
board.
Keep hands on the outside of steering
wheel rim. Placing hands and arms in-
side the rim can increase the risk and
potential severity of hand/arm injury
when driver front air bag 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 air bag inflates.
This could result in serious injuries or
death should the air bag be triggered.
Always sit nearly upright, properly use
the seat belts and appropriate size in-
fant 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 deacti-
vate the passenger front air bag when it
is properly installed. Otherwise they will
be struck by the air bag when it inflates
in a crash. If this happens, serious or fa-
tal injury will result.
Failure to follow these instructions can re-
sult in severe injuries to you or other occu-
pants.
If you sell your vehicle, it is important that
you make the buyer aware of this safety in-
formation. Be sure to give the buyer this
Operator’s Manual.
Warning!
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 front air bag.
BabySmart
TM will not, however, turn off any
side impact air bag.
It should be noted that with respect to both
front and rear side impact air bags there is a
possibility for a side air bag related injury if
occupants, especially children, are not prop-
erly seated or restrained when next to a side
air bag 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 air bag inflates. This could result in

air bagWarning!
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 in-
stalled or supplied by an authorized
Mercedes-Benz Center.
Air bags and emergency tensioning de-
vices (ETDs) are designed to function on
a one-time-only basis. An air bag or ETD
that was activated must be replaced.
No modifications of any kind may be
made to any components or wiring of
the SRS. This includes changing or re-
moving any component or part of the
SRS, the installation of additional trim
material, badges, etc. over the steering
wheel hub, passenger front air bag
cover, outboard sides of the front seat
backrests, door trim panels, or door
frame trims, and installation of addition-
al electrical/electronic equipment on or
near SRS components and wiring. Keep
area between air bags and occupants
free from objects (e.g. packages, purs-
es, umbrellas, etc.).
Do not pass belts over sharp edges.
They could tear.
Do not make any modification that could
change the effectiveness of the belts.
Do not bleach or dye seat belts as this
may severely weaken them. In a crash
they may not be able to provide ade-
quate protection.
Do not hang items such as coat hangers
from the coat hooks or handles over the
door. These items may turn into projec-
tiles and cause head and other injuries
when curtain air bag is deployed.
Never place your feet on the instrument
panel, dashboard, or on the seat. Always
keep both feet on the floor in front of the
seat.
Air bag system components will be hot
after the air bag has inflated. Do not
touch.
In addition, improper repair work on the
SRS creates a risk of rendering the SRS
inoperative or causing unintended
air bag deployment. Work on the SRS
must therefore only be performed by
qualified technicians. Contact an autho-
rized Mercedes-Benz Center.
For your protection and the protection
of others, when scrapping the air bag
unit or emergency tensioning device,
our safety instructions must be fol-
lowed. These instructions are available
from your authorized Mercedes-Benz
Center.
Given the considerable deployment
speed and the textile structure of the
air bags, there is the possibility of abra-
sions or other injuries resulting from
air bag deployment.
68 Safety and SecurityOccupant safetyThe side impact air bags are deployed:
in impacts exceeding a preset deploy-
ment threshold
on the impacted side of the vehicle
independently of the front air bags
The side impact air bags are not deployed
in impacts which do not exceed the sys-
tem’s deployment threshold.
The front passenger side impact air bag
will only deploy if the system senses that
the front passenger seat is occupied.
Window curtain air bags

Seat belts
When the engine is started, the seat belt
telltale< illuminates to remind you and
your passengers to fasten your seat belts.
If the driver’s seat belt is not fastened be-
fore the engine is started, the seat belt
telltale< illuminates and a warning
chime sounds for approximately 6 seconds
when the engine is started.
Always wear your seat belt. All vehicle oc-
cupants always need to have their seat
belts fastened and wear them properly.
In addition, applicable motor vehicle safety
laws require you to wear seat belts. Even
where this is not the case, we strongly rec-
ommend that all vehicle occupants have
their seat belts fastened and wear them
properly.
For more information, see “Fastening the
seat belts” (
page 45).

dren, see “Children in the vehicle”
(page 72).
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. Air bags can only protect as
they are designed if the occupants are prop-
erly wearing their seat belts.
Warning!
G
Never ride in a moving vehicle with the seat
backrest in an excessively reclined position
as this 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 ab-
domen or neck. That could cause serious or
even fatal injuries. The seat backrest and
seat belt provide the best restraint when the
wearer is in a nearly upright position and the
belt is properly positioned on the body.Warning!
G
Never let more people ride in the vehicle
than there are seat belts available. Be sure
everyone riding in the vehicle is correctly re-
strained with a separate seat belt. Never use
a seat belt for more than one person at a
time.

USE SEAT BELTS PROPERLY
Seat belts can only work when used
properly. Never wear seat belts in any
other way than as described in this sec-
tion, as that could result in serious inju-
ries in case of an accident.
Each occupant should wear their seat
belt at all times, because seat belts help
reduce the likelihood of and potential
severity of injuries in accidents, includ-
ing rollovers. The integrated restraint
system includes SRS (driver’s air bag,
passenger front air bag, side impact
air bags, head protection window cur-
tain air bags for side windows), ETD
(seat belt emergency tensioning device),
and front seat knee bolsters. The sys-
tem is designed to enhance the protec-
tion offered to properly belted
occupants in certain frontal (front
air bags and ETD) and side (side impact,
window curtain air bags and ETD) im-
pacts which exceed preset deployment
thresholds and in certain rollovers
(window curtain air bags and ETD).
Never wear the shoulder belt under your
arm, against your neck or off your shoul-
der. In a crash, your body would move
too far forward. That would increase the
chance of head and neck injuries. The
belt would also apply too much force to
the ribs or abdomen, which could se-
verely injure internal organs such as
your liver or spleen.
Never wear belts over rigid or breakable
objects in or on your clothing, such as
eyeglasses, pens, keys, etc., as these
might cause injuries.
Position the lap belt as low as possible
on your hips and not across the abdo-
m e n . I f t h e b e l t i s p o s i t i o n e d a c r o s s y o u r
abdomen, it could cause serious injuries
in a crash.
Never use a seat belt for more than one
person at a time. Do not fasten a seat
belt around a person and another per-
son or other objects.
71 Safety and Security
Occupant safety
Emergency tensioning device (ETD),
seat belt force limiter
The seat belts for the front and rear outer
seats are equipped with emergency ten-
sioning devices and belt force limiters.
The ETD is designed to activate in the fol-
lowing cases:
in frontal or rear-end impacts exceed-
ing a preset severity level
in certain vehicle rollovers
if the restraint systems are operational
and functioning correctly, see
1indicator lamp (
page 62).
In an impact, emergency tensioning devic-
es remove slack from the belts in such a
way that the seat belts fit more snugly
against the body. Belt force limiters reduce
the force exerted by the seat belts on oc-
cupants during a crash.
Automatic comfort-fit feature seat belt
An automatic comfort-fit feature for front
seats reduces the retracting force of the
seat belts when they are in normal use.
Belts should not be worn twisted. In a
crash, you wouldn’t have the full width
of the belt to manage impact forces. The
twisted belt against your body could
cause injuries.
Pregnant women should also use a
lap-shoulder belt. The lap belt portion
should be positioned as low as possible
on the hips to avoid any possible pres-
sure on the abdomen.
Never place your feet on the instrument
panel, dashboard or on the seat. Always
keep both feet on the floor in front of the
seat.
iThe ETDs for the front seats will only
activate if the respective front seat belt
is fastened (latch plate properly insert-
ed into buckle).
The ETDs for the rear outer seats will
activate with or without the respective
seat belt fastened.
Warning!
G
An emergency tensioning device (ETD) that
was activated must be replaced.
When disposing of the emergency tension-
ing device, our safety instructions must be
followed. These are available at your autho-
rized Mercedes-Benz Center.!Do not place objects heavier than
20 lbs (9 kg) on the front passenger
seat. This could cause the front or side
impact air bag on the front passenger
side and, with the seat belt fastened to
secure the object, the ETD to deploy in
a crash which exceeds the system’s de-
ployment threshold.
72 Safety and SecurityOccupant safetyChildren in the vehicle
If an infant or child is traveling with you in
the vehicle:
Secure the child using an infant or child
restraint appropriate to the age and
size of the child.
Make sure the infant or child is proper-
ly secured at all times while the vehicle
is in motion.
Infant and child restraint seats and infor-
mation on choosing an appropriate re-
straint system can be obtained from any
Mercedes-Benz Center.Infant and child restraint systems
Use only a BabySmart
TM compatible child
restraint for the front passenger seat in
this vehicle.
We recommend all infants and children be
properly restrained at all times while the
vehicle is in motion.
All lap-shoulder belts except the driver’s
seat belt have special seat belt retractors
for secure fastening of child restraints.
To fasten a child restraint, follow child re-
straint instructions for mounting. Then pull
the shoulder belt out completely and let it
retract. During seat belt retraction, a ratch-
eting sound can be heard to indicate that
the special seat belt retractor is activated.
The belt is now locked. Push down on child
restraint to take up any slack.
To deactivate, release seat belt buckle and
let seat belt retract completely. The seat
belt can again be used in the usual man-
ner.

with mounting fittings for tether an-
chorages, see “Installation of infant
and child restraint systems”
(page 76).

seat mounts (
page 77).
Warning!
G
Never release the seat belt buckle while the
vehicle is in motion, since the special seat
belt retractor will be deactivated.!The use of infant or child restraints is
required by law in all 50 states, the Dis-
trict of Columbia, the U.S. territories
and all Canadian provinces.
Infants and small children should be
seated in an appropriate infant or child
restraint system properly secured by
73 Safety and Security
Occupant safety
a lap-shoulder belt or, if so equipped, a
child restraint lower anchorage system
that complies with U.S. Federal Motor
Vehicle Safety Standards 213 and 225
and Canadian Motor Vehicle Safety
Standards 213 and 210.2.
A statement by the child restraint man-
ufacturer of compliance with this stan-
dard can be found on the instruction
label on the restraint and in the instruc-
tion manual provided with the restraint.
When using any infant or child restraint
system, be sure to carefully read and
follow all manufacturer’s instructions
for installation and use.
Please read and observe warning labels
affixed to inside of vehicle and to infant
or child restraints.
Warning!
G
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
BabySmart
TM System installed in the vehicle
to deactivate the passenger front air bag
when it is properly installed. Otherwise they
will be struck by the air bag when it inflates
in a crash. If this happens, serious or fatal in-
jury will result.
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 and top tether strap, or secured via
lower anchors and top tether strap, fully in
accordance with the child seat manufactur-
er’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.
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.
When the child restraint is not in use, re-
move 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 ac-
cident.
