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.

Restraints in Index. Whenever restraints have been removed be sure to reinstall them before driving.

Multicontour Seat (optional)
We recommend to adjust the multicontour seat in the following order:
1. Seat cushion depth
2. Backrest bottom
3. Backrest center
4. Side bolster adjustment
Some models may be equipped with multicontour seats. These seats have movable seat cushions,
and inflatable air cushions built into the backrest to provide additional lumbar and side support.
The seat cushion movement and amount of backrest cushion height and curvature can be
continuously varied with regulators (1, 2 and 3) after turning the electronic key in steering lock to
position 2.
The side bolsters of the backrest can be adjusted with rocker switch (4):
• press down forward end-increase side support,
• press down rearward end-decrease side support.
If the engine is turned off, the last cushion setting is retained in memory, and automatically adjusts
the cushion to this setting when the engine is restarted.

Heated Seats (optional)
Heated Seats (optional)
The front seat heater can be switched on with the electronic key in steering lock
positions 1 or 2.
Press switch to turn on seat heater:
1. Normal seat heating mode. One indicator lamp in the switch lights up.
2. Rapid seat heating mode. Both indicator lamps in the switch light up. After
approximately 5 minutes in the rapid seat heating mode, the seat heater automatically
switches to normal operation and only one indicator lamp will stay on.
Turning off seat heater:
If one indicator lamp is on, press upper half of switch.
If both indicator lamps are on, press lower half of switch.
If left on, the seatheater automatically turns off after approximately 30 minutes of operation.
Note:
When in operation, the seat heater consumes a large amount of electrical power. It is not advisable to use the seat
heater longer than necessary. The seat heaters may automatically switch off if too many power consumers are
switched on at the same time, or if the battery charge is low. When this occurs, the indicator lamp in the switch will
blink (both indicator lamps blink during rapid seat heating mode). The seat heaters will switch on again automatically
as soon as sufficient voltage is available. If the blinking of the indicator lamps is distracting to you, the seat heaters
can be switched off.

Adjusting Telescoping Steering Column (optional)
Warning!
Do not adjust the steering wheel while driving. The telescoping
