KEYLESS-GO
Important!
For the KEYLESS-GO-system to function properly, the
operator should observe the following:
•The driver should carry the KEYLESS-GO-card with
him / her.
•To avoid radio transmission interference, never store
the KEYLESS-GO-card together with other electronic
items (e.g. cellular telephones, other KEYLESS-GO-
cards) or metallic objects (e.g. coins, metal foil).
•To lock or unlock the vehicle, the card must be
recognized by the system as being located outside
the vehicle. The card must be in close proximity to a
door or the trunk lid (approx. 3 ft. [1 m]). To activate
the start / stop button function, the KEYLESS-GO-
card must be recognized by the system as being
located inside the vehicle.
•If the KEYLESS-GO-card is positioned farther away
from the vehicle (e.g. inside clothing or a briefcase)
and can no longer be recognized by the system, the
vehicle cannot be locked or the engine started via
the KEYLESS-GO-system.•If the KEYLESS-GO-card is removed from the vehicle
while the engine is running, or by placing the card
in front of the center armrest (see page 195), the
message “CHIP-CARD – NOT RECOGNIZED!” will
appear repeatedly in the multifunction display,
seepage322.
Find the card or change its present location (e.g.
place it on the front passenger seat or insert it in
shirt pocket).
•If the message “CHIP - CARD – NOT RECOGNIZED”
is ignored for an extended of time (approx.
15 minutes), the engine could stop by itself during a
vehicle stop (e.g. traffic light). The vehicle can then
no longer be centrally locked or the engine
restarted. You must first find the card or change its
present location (e.g. place it on the front passenger
seat or insert it in shirt pocket). Start the engine
again. See page 228.
•Do not forget, the engine can be started by anyone
with a KEYLESS-GO-card that is left inside the
vehicle. Leaving the chip-card behind when exiting
and locking the vehicle, the message “CHIP-CARD –
STILL IN VEHICLE” appears in the multifunction
display, see page 322.

To operate the front power seat adjustment switches,
turn the electronic key in starter switch to position 1
or 2 (with a front door open, the power seats can also be
operated with the electronic key removed or in starter
switch position 0).
Wa r n i n g !
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 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.Never place hands under seat or near any moving
parts while a seat is being adjusted.
When leaving the vehicle always remove the
electronic key from the starter switch, take the
KEYLESS-GO-card (if so equipped) with you, and
lock your vehicle. The power seats can also be operated with the
driver’s or front 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.

Important!
Prior to operating the vehicle, the driver should adjust
the seat height for proper vision as well as fore/aft
placement and backrest angle to insure adequate
control, reach, operation, and comfort. The head
restraint should also be adjusted for proper height. See
also airbag section on page 94 for proper seat
positioning.
In addition, also adjust the steering wheel to ensure
adequate control, reach, operation, and comfort.
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
Stand ard 213.

Wa r n i n 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 the BabySmart
TM 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
child 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.
