34 Getting startedAdjusting
AdjustingSeatsWarning!
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 reclined. Sitting in an excessively re-
clined 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 se-
rious 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.
Your seat must be adjusted so that you can
correctly fasten your seat belt.
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 starter switch, take the Smart-
Key with KEYLESS-GO* (if so equipped) with
you, and lock your vehicle.
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. Unsu-
pervised use of vehicle equipment may
cause an accident and/or serious personal
injury.
Warning!
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 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.
35 Getting started

position should be as far to the rear as
possible, consistent with ability to
properly operate controls.
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.
iWhen moving the seat, be sure that
there are no items in the footwell or be-
hind the seats. Otherwise you could
damage the seats.

ered.
Warning!
G
Do not adjust the steering wheel while driv-
ing. Adjusting the steering wheel while driv-
ing could cause the driver to lose control of
the vehicle.
When leaving the vehicle always remove the
key from the starter switch, take the Smart-
Key with KEYLESS-GO* (if so equipped) with
you and lock your vehicle.
The electrical steering wheel adjustment
feature can also be operated with the driv-
er’s door open. Do not leave children unat-
tended in the vehicle, or with access to an
unlocked vehicle. Unsupervised use of vehi-
cle equipment may cause an accident
and/or serious personal injury.
40 Getting startedDriving
Driving
Fastening the seat belts
Warning!
G
Do not lay any objects in the driver’s foot-
well. Be careful that floor mats or carpets in
the driver’s footwell have sufficient clear-
ance for the pedals.
During sudden driving or braking maneu-
vers, the objects could get caught between
the pedals. You could then no longer brake
or accelerate.
Warning!
G
Always fasten your seat belt before driving
off. Always make sure your passengers are
properly restrained, even those sitting in the
rear and pregnant women.
Failure to wear and properly fasten and po-
sition your seat belt greatly increases your
risk of injuries and their likely severity in an
accident. You and your passengers should
always wear seat belts.
If you are ever in an accident, your injuries
can be considerably more severe without
your seat belt properly buckled. Without
your seat belt buckled, you are much more
likely to hit the interior of the vehicle or be
ejected from it. You can be seriously injured
or killed.
In the same crash, the possibility of injury or
death is lessened if you are wearing your
seat belt. The airbags can only protect as ex-
pected if the occupants are using their seat
belts (
page 56).
Warning!
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 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.
41 Getting started
Driving
The seat belt presenter for driver and pas-
senger makes it easier to put on the seat
belt.
1Seat belt presenter
The seat belt presenter slides out when the
corresponding door is closed and the key
is turned in the starter switch to
position2.
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.
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.Warning!
G
Never let more people ride in the vehicle
than there are seat belts available. Be sure
everyone riding in the vehicle is correctly re-
strained with a separate seat belt.
Warning!
G
Never ride in a moving vehicle with the seat
backrest 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. This could
cause serious or even fatal injuries. The seat
backrest and seat belt provide the best re-
straint when the wearer is in an upright po-
sition and the belt is properly positioned on
the body.Warning!
G
Read and observe the additional warning no-
tices printed in the “Safety and Security”
section (
page 60).

which could result in an accident and/or se-
rious personal injury.Warning!

gerous. Also, when parked on an incline,
