Adjusting
Adjusting
Seats
The seats can be adjusted either manually
or electrically, depending on the vehicle’s
equipment.Warning!
G
All seat, head restraint, steering wheel, and
rear view mirror adjustments, as well as fas-
tening of seat belts, must be done before
the vehicle is put into motion.Warning!
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 in an excessively reclined position as
this can be dangerous. You could slide un-
der the seat belt in a collision. If you slide
under it, the belt would apply force at the ab-
domen 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 nearly
upright position and belts are properly posi-
tioned on the body. Your seat must be ad-
justed so that you can correctly fasten your
seat belt (
page 43).
Never place hands under the seat or near
any moving parts while a seat is being ad-
justed.
Warning!
G
When leaving the vehicle, always remove the
key from the steering lock and lock your
vehicle.
Even with the key removed from the steer-
ing lock, the power seats* can also be oper-
ated when the respective door is open.
Therefore, do not leave children unattended
in the vehicle, or with access to an unlocked
vehicle. Unsupervised use of vehicle equip-
ment may cause an accident and / or seri-
ous personal injury.
Warning!
G
Children 12 years old and under must never
ride in the front seat, except in a
Mercedes-Benz authorized BabySmart
TM1
compatible child seat, which operates with
the BabySmart
TM system installed in the ve-
hicle to deactivate the passenger front air-
bag when it is properly installed. Otherwise
they will be struck by the airbag when it in-
flates 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 seat-
ing 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 and top tether strap, or secured via
lower anchors and top tether strap, fully in
accordance with the child seat manufactur-
er’s instructions.

Driving
After a cold start, the automatic transmis-
sion shifts at a higher engine revolution.
This allows the catalytic converter to reach
its operating temperature earlier.
For more information, see “Driving instruc-
tions” (
page 197).
For information on off-road driving, see
“Off-road driving” (
page 204).
!If you hear a warning signal when driv-
ing off, you have forgotten to release
the parking brake.
Release the parking brake.Warning!
G
It is dangerous to shift the gear selector
lever out ofP orN if the engine speed is
higher than idle speed. If your foot is not
firmly on the brake pedal, the vehicle could
accelerate quickly forward or in reverse. You
could lose control of the vehicle and hit
someone or something. Only shift into gear
when the engine is idling normally and when
your right foot is firmly on the brake pedal.
Warning!
G
On slippery road surfaces, never downshift
in order to obtain braking action. This could
result in drive wheel slip and reduced vehi-
cle control. Your vehicle’s ABS will not pre-
vent this type of loss of control.!Place the gear selector lever in
positionR only when the vehicle is
stopped in order to avoid damaging the
transmission.
!Do not run cold engine at high engine
speeds. Running a cold engine at high
engine speeds may shorten the service
life of the engine.!Simultaneously depressing the acceler-
ator pedal and applying the brake re-
duces engine performance and causes
premature brake and drivetrain wear.
