Safety notes
G
Warning!
In order to avoid possible loss of vehicle
control
the following must be done before the
vehicle is put into motion:
R seat adjustment
R head restraint adjustment
R steering wheel adjustment
R rear view mirror adjustment
R fastening of seat belts G
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
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 seat belt would apply force at the
abdomen or neck. That could cause serious
or fatal injuries. The seat backrest and seat
belts provide the best restraint when the
wearer is in a position that is as upright as
possible and seat belts are properly
positioned on the body. G
Warning!
Your seat must be adjusted so that you can
correctly fasten your seat belt.
Observe the following points:
R Adjust

the seat backrest until your arms are
slightly angled when holding the steering
wheel.
R Adjust the seat to a comfortable seating
position that still allows you to reach the
accelerator/brake pedal safely. The
position should be as far back as possible
with the driver still able to operate the
controls properly. Seats

Notes
i If you drive in countries with left-hand
driving, you must have the headlamps
modified for symmetrical low beams.
Relevant information can be obtained at
any authorized Mercedes-Benz Center.
i Vehicles equipped with active Bi-Xenon
headlamps:
The active Bi-Xenon headlamps increase
usable illumination over conventional
headlamps because they follow the
curvature of the road ahead. The beams of
the active Bi-Xenon headlamps shift to
either side according to the vehicle’s
steering angle and speed. Exterior lamp switch
