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


A - Seat, fore/aft
B - Seat, up/down
C - Seat tilt
D - Backrest tilt
E - 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
The slide switches are located in each front door. Turn elec tronic 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 co vers. 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 driv er 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 prope r seat positioning. 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 213.1. All seat, head restraint, 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.

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 insta lled, 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.

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 manufacture r'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, or otherwise do not transport child restraints 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 li t, the system is not functioning. You must see an
authorized Mercedes-Benz dealer before using any child seat.

Airbags

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




The most effective occupant restraint system yet developed fo
r 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 or rear impacts (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. 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 (when present). 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). In the operational mode, after the indicator lamp has gone
out following the initial check, interruptions or short circ uits 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 unneccesarily which could also result in
injury.


Front Airbags
The driver and passenger front "SRS" airbags are designed to activate only in certain frontal or rear impacts.
The front passenger airbag deploys only if the passenger seat is occupied.

Note:

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


Side Impact Airbags
The side impact "SRS" airbags are designed to activate onl y in certain side impacts. Only the side airbag on the
impacted side of the vehicle deploys. The side impact ai rbag for the front passenger deploys only if the seat is
occupied. Side impact airbags operate best in conjunct ion with a properly positioned and fastened seat belt.
Note:
Heavy objects on passenger seat can cause the side impact airbag to deploy in a crash

Loading instructions
(Vehicles with enlarged cargo area)

The total load weight including vehicle occupants and luggage/ cargo should not exceed the vehicle capacity weight
indicated on the certification tag which can be found on t he left door pillar. The handling characteristics of a fully
loaded vehicle depend greatly on the load distribution. It is therefore recommended to load the vehicle according to
the illustrations shown, with the heavie st items being placed towards the front of the vehicle. Always place items
being carried against front or rear seat backrests, and fast en them as securely as possible. The heaviest portion of
the cargo should always be kept as low as possible since it influences the handling characteristics of the vehicle.

Notes:
The trunk is the preferred place to carry objects. T he enlarged cargo area should only be used for items which
do not fit in the trunk alone.

Warning !
In an accident, during hard braking or sudden maneuvers, loose items will be thrown around inside the
vehicle, and can cause injury to vehicle occupants unless the items are securely fastened in the vehicle.
To help avoid personal injury during a collision or sudden maneuver, exercise care when stowing things.
Put luggage or cargo in the trunk if possible. Do not pile luggage or cargo higher than the seat backs.
Do not place anything on the shelf below the rear window. Never drive vehicle with trunk lid open while
pass-through is not closed and seat backrest not locked in its upright position. Deadly carbon monoxide
(CO) gases may enter vehicle interior resulting in unconsciousness and death.

Notes:
A warning sounds when the driver's door is opened with the el ectronic key in steering lock position 1 or 0. With the
engine at idle speed, the charging rate of the alternator (output) is limited. It is therefore recommended to turn off
unnecessary electrical consumers while driving in stop-and-go traffic. This precaution helps to avoid draining of the
battery. Unnecessary strain on the batte ry and charging system may be minimized by turning off the following power
consumers, for example: Heated seats, rear window defroster. In addition, the automatic climate air volume control
should be set to the lowest position. The steering lock can only be unlocked with the vehicle battery properly
connected.
