Vehicles with KEYLESS-GO*: In addition to
the two SmartKeys with remote controls
and removable mechanical key, your vehi-

KEYLESS-GO* cards.
The function of the SmartKey overrules the
KEYLESS-GO function.If you have the KEYLESS-GO function, your
vehicle checks whether the KEYLESS-GO
card is valid when you grasp the door han-
dle. If your KEYLESS-GO card is valid, the
doors will unlock, and you can open them.

34 Getting startedAdjusting
Adjusting
Seats
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 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 backrest 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
SmartKey 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 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.

35 Getting started
Adjusting
Seat adjustment
The seat adjustment switches are located
on the front doors.
1Head restraint height
2Seat height
3Seat cushion tilt
4Seat cushion depth
5Seat fore and aft adjustment
6Seat backrest tilt
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 front passenger 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.
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.

Steering wheel
Warning!
G
For your protection, drive only with properly
positioned head restraints.
Adjust head restraint to support the back of
the head approximately at ear level.
Do not drive the vehicle without the seat
head restraints. Head restraints are intend-
ed to help reduce injuries during an acci-
dent.
iThe front passenger seat head restraint
automatically lowers after a few sec-
onds when the front passenger seat is
not occupied. This improves the driv-
er’s outward view as well as the for-
ward view from the rear passenger
compartment.
When the front passenger seat is occu-
pied again, the front passenger seat
head restraint returns to the last set
position within a few seconds.
If the front passenger seat was moved
fore or aft while not being occupied,
the front passenger seat head restraint
returns to a position that corresponds
best with the seat’s axial position when
the seat is occupied again.
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
SmartKey from the starter switch, and take
the KEYLESS-GO
* card (if so equipped) with
you.
The steering wheel adjustment feature can
also be operated with the driver’s door
open. 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 serious
personal injury.

G
In the case of an accident liquid electrolyte
may escape the mirror housing if the mirror
glass breaks.
Electrolyte has an irritating effect. Do not al-
low the liquid to come into contact with
eyes, skin, clothing, or respiratory system.
In case it does, immediately flush affected
area with water, and seek medical help if
necessary.

exterior rear view mirrors, see “Folding the
exterior mirrors in and out automatically”
(
page 170).
Warning!
G
Exercise care when using the passenger
side exterior rear view mirror. The mirror
surface is convex (outwardly curved surface
for a wider field of view). Objects in mirror
are closer than they appear. Check your in-
side rear view mirror or glance over your
shoulder before changing lanes.!Electrolyte drops coming into contact
with the vehicle paint finish can only be
completely removed while in their liq-
uid state and by applying plenty of wa-
ter.
!For information on how to reposition
the exterior mirror housing when it was
forcibly pushed forward (hit from the
rear) or forcibly pushed rearward (hit
from the front), see “Folding the exteri-
or mirrors in and out manually”
(page 170).
iAt low ambient temperatures, the mir-
rors will be heated automatically.

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 maneuvers
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 passenger should al-
ways 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 front passenger air-
bag when it is properly installed. Otherwise
