Seats, Front

Warning !
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
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. That could cause serious or even fatal injuries. The seat backrest and seat belt provide
the best restraint when the wearer is in an upright position and the belt is property positioned on the body.
Never place hands under seat or near any moving parts while a seat is being adjusted

1 - Seat, up/down
2 - Seat, fore7aft
3 - Seat cushion tilt
4 - Backrest tilt
5 - Head restraint

Adjust head restraint to support the back of the head approximately at ear level.
The head restraint angle can also be adjusted manually.
Note:
Your car is equipped with power head restraints, do not try to raise or lower them manually.


Power Seat (Optional on model C230 Kompressor passenger side)
The slide switches are located in each front door. Turn electronic key in steering lock to position 1 or 2 (with a front
door open, the power seats can also be operated with the electronic key removed or in steering lock position 0).

Warning !
When leaving the vehicle always remove the electronic key from the steering lock. 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. Unsupervised use of vehicle equipment may cause serious personal injury.

Caution !
Do not remove head restraints except when mounting seat covers. For removal refer to Head Restraints, Front, see
Index. Whenever restraints have been removed be sure to reinstall them
before driving.

Important !
Prior to operating the vehicle, the driver should adjust the seat height for proper vision as well as fore/aft placement
and seat back angle to insure adequate control, reach, operation, and comfort. The head restraint should also be
adjusted for proper height. See also airbag section for proper seat positioning. In addition, also adjust the steering
wheel to ensure
adequate control, reach, operation, and comfort, if vehicle so equipped. Both the inside and outside rear view mirrors
should be adjusted for adequate rearward vision. Fasten seat belts. Infants and small children should be seated in a
properly secured restraint system that complies with U.S. Federal Motor Vehicle Safety Standard 213 and Canadian
Motor Vehicle Safety Standard 213. All seat, head restraint, steering wheel, and rear view mirror adjustments as well
as fastening of seat belts should be done before the vehicle is put into motion.

Warning !
Children 12 years old and under must never ride in the front seat, except in a Mercedes-Benz authorized
BabySmart™ compatible child seat, which operates with the BabySmart™ system installed in the vehicle to
deactivate the passenger side 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 will result. The back seat is the safest place
for children. Infants and small children must ride in the back seats and be seated in an appropriate infant or
child restraint system, which is properly secured with the vehicle's seat belt, fully in accordance with the 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.

Seat Belts and Supplemental Restraint System (SRS)

Your vehicle is equipped with seat belts for all se ats, emergency tensioning retractors for the front
seats, as well as front and side impact airbag s and knee bolsters for driver and front passenger.

Seat Belts

Important !
Laws in most states and all Canadian provinces require seat belt use. All states and provinces
require use of child restraints that comply with U.S. Federal Motor Vehicle Safety Standard 213 and
Canadian Motor Vehicle Safety Standard 213

All child restraint systems are designed to be secure d in vehicle seats by lap belts or the lap belt
portion of a lap-shoulder belt.

For your safety and that of your pass engers we strongly recommend their use.

Warning !
Children 12 years old and under must never ride in the front seat, except in a Mercedes-Benz
authorized BabySmart™ compatible child seat, which operates with the BabySmart™ system
installed in the vehicle to deactivate the passenger side 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 will result. The back seat is the safest place for children.
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, fully in
accordance with the 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 !
Never ride in a moving vehicle with the seat back 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. That could cause serious or even
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.


Seat Belt Warning System
With the electronic key in steering lock position 2, a warning sounds for a short time if the driver's
seat belt is not fastened.

Warning !
Failure to wear and properly fasten and position 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 for injury or death is lessened with your seat belt
buckled.

Warning !

USE SEAT BELTS PROPERLY.
• 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, including rollovers. "SRS" (driver
airbag, front passenger airbag, front door side impact airbags), "ETR" (seat belt emergency
tensioning retractors), and knee bolsters are impacts which exceed preset deployment thresholds.
• Improperly positioned seat belts do not provide maximum protection and may
cause serious injuries in case of an accident.
• Never wear the shoulder belt under your arm, against your neck or off your shoulder. 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
severely injure infernal organs such as your liver or spleen.

• Position the lap belt as low as possible on your hips and not across the abdomen. If the
belt is positioned across your abdomen, it could cause serious injuries in a crash.
• Each seat belt should never be used for more than one person at a time. Do not fasten a
seat belt around a person and objects.
• 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 pressure on the abdomen.

Warning !

USE CHILD RESTRA INTS PROPERLY.
Children 12 years old and under must never ride in the front seat, except in a Mercedes-Benz
authorized Baby Smart™ compatible child seat, which operates with the BabySmart™ system
installed in the vehicle to deactivate the passenger side 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 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, fully in accordance with the seat manufacturer's instructions.
A child's risk of serious or fatal injuries is signi ficantly increased if the child restraints are not
properly secured in the vehicle and the child is not properly secured in the child restraint.
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.

BabySmart™ Airbag Deactivation System

Special child seats, designed for use with the Mercedes-Benz system and available at any
authorized Mercedes-Benz dealer are required for use with the BabySmart™ airbag deactivation
system. With the special child seat properly installed, the passenger front airbag will not deploy. The
indicator lamp located on the center console will be illuminated, except with electronic key
removed or in steering lock position 0. The system does not deactivate the door mounted side
impact airbag.

BabySmart is a trademark of Siemens Automotive Corp.

Warning !

The BabySmart™ Airbag Deactivation System will ONLY work with a special seat designed to
operate with it. It will not work with seats which are not BabySmart™ compatible. Never place
anything between seat cushion and child seat (e.g. pillow), since it reduces the effectiveness
of the deactivation system. Follow the manufacturer's instructions for installation of special
child seats. The passenger side front airbag will not deploy only if the indicator lamp
remains illuminated. Please be sure to check the indicator every time you use the special
system child seat. Should the light go out while the restraint is installed, please check
installation. If the light remains out, do not use the BabySmart™ restraint to transport
children, on the front passenger seat until the system has been repaired.


Self-Test BabySmart™ Without Special Child Seat Installed
After turning electronic key in steering lock to position 1 or 2, the indicator lamp located on
center console comes on for approx. 6 seconds.
If the lamp should not come on or is continuously lit, the system is not functioning. You must see an
authorized Mercedes-Benz dealer before using any child seat on the front passenger seat.

Supplemental Restraint System (SRS)

The term Supplemental Restraint System means that airbags are intended as a supplement to seat
belts. Airbags alone cannot protect as well as airbags plus seat belts in impacts for which the
airbags were designed to operate, and do not afford any protection whatsoever in crashes for which
the system is not designed to deploy. The SRS us es two crash severity levels (thresholds) to
activate either the Emergency tensioning retrac tor (ETR) or airbag or both. Activation depends on
the direction and severity of the impact, exceedi ng the thresholds and fastening of the seat belt.

Seat belt fastened
• first threshold exceeded:
ETR activates
• second threshold exceeded:
airbag also activates

Seat belt not fastened
• first threshold exceeded:
airbag activates, but not ETR
Driver and front passenger systems opera te independently from each other.

Airbags

1. Driver airbag
2. Front passenger airbag
3. Side impact airbag





The most effective occupant restraint system yet developed for use in production vehicles is the seat belt. In some
cases, however, the protective effect of a seat belt can be further enhanced by an airbag. The driver airbag is located
in the steering wheel hub. The passenger airbag is located in the dashboard ahead of the passenger.
The side impact airbags are located in the front doors. In conjunction with wearing the seat belts with emergency
tensioning retractors, the airbags can provide increased protection for the driver and passenger in certain major
frontal (for front airbags) and side impacts (for side impact airbags). 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 fault 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.
The following system components are monitored or undergo a self-check: crash-sensor(s), airbag ignition circuits,
front seat belt buckles, emergency tensioning retractors, seat sensor . Initially, when the electronic key is turned from
steering lock position 0 to positions 1 or 2, malfunctions in the crash-sensor are detected and indicated (the "SRS"
indicator lamp stays on longer than 4 seconds or does not come on). Have the system checked at your authorized
Merzedes-Benz dealer immediately. In the operational mode, after the indicator lamp has gone out following the initial
check, interruptions or short circuits in the airbag ignition circuit and in the driver and passenger seat belt buckle
harnesses, and low voltage in the entire system are detected and indicated.

Warning !
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 dealer 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.


Front Airbags
The driver and passenger front "SRS" airbags are designed to activate only in certain frontal impacts.
The front passenger airbag deploys only if the front passenger seat is occupied and the indicator lamp on the
center console is not illuminated.

Note:
Heavy objects on front passenger seat can cause the passenger front airbag to deploy in a crash.


Side Impact Airbags
The side impact "SRS" airbags are designed to activate only in certain side impacts. Only the side impact airbag on
the impacted side of the vehicle deploys. The side impact airbag for the front passenger deploys only if the front
passenger
seat is occupied. Side impact airbags operate best in conjunction with a properly positioned and fastened seat belt.

Note:
Heavy objects on front passenger seat can cause the side impact airbag to deploy in a crash.
