32 Getting startedAdjusting
AdjustingSeats
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 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 serious or fatal injuries.
The seat back and seat belts provide the
best restraint when the wearer is in an up-
right position and belts are properly posi-
tioned on the body. Your seat must be
adjusted so that you can correctly fasten
your seat belt (
page 41).
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 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.

Getting started
Driving
 Driving
Fastening the seat beltWarning!
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 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

Safety and Security
Occupant safety
quarter trim panels where the side air-
bag inflates. This could result in serious
injuries or death should the side airbag
be activated.
(2) Always sit upright, properly use the seat belts and use an appropriately sized in-
fant or child restraint system for all chil-
dren 12 years old or under.
(3) Always wear seat belts properly.
If you believe that, even with the use of
these guidelines, it would be safer for your
rear seat occupants to have both rear side
airbags deactivated, then deactivation can
be accomplished upon your written request
to do so at your authorized Mercedes-Benz
Center at an additional cost.
Please contact your local authorized
Mercedes-Benz Center or call our Customer
Assistance Center at 1-800-FOR-MERCedes
(1-800-367-6372) for details.
iAirbags are designed to activate only in
certain frontal impacts (front airbags)
and in side impacts (side impact and
head protection window curtain air-
bags) which exceed preset thresholds.
Only during these types of impacts, if of
sufficient severity to meet the deploy-
ment tresholds, will they provide their
supplemental protection.
The driver and passengers should
always wear their seat belts. Otherwise
it is not possible for airbags to provide
their supplemental protection.
In cases of other frontal impacts,
angled impacts, roll-overs, other side
impacts, rear collisions, or other acci-
dents, the airbags will not be activated.
The driver and passengers will then be
protected by the fastened seat belts.
We caution you not to rely on the pres-
ence of the airbags in order to avoid
wearing your seat belt.
Your vehicle was originally equipped
with airbags that are designed to acti-
vate in certain impacts exceeding a
preset threshold to reduce the poten-
tial and severity of injury. It is important
to your safety and that of your passen-
ger that you replace deployed airbags
and repair any malfunctioning airbags
to ensure that the vehicle will continue
to provide supplement crash protec-
tion for occupants.

Children in the vehicle
If an infant or child is traveling with you in
the vehicle:

Secure the child using an infant or child
restraint appropriate to the age and
size of the child and recommended for
use by Mercedes-Benz.


Ensure that the infant or child is prop-
erly secured by a belt at all times while
the vehicle is in motion.
Infant and child restraint seats and infor-
mation on choosing an appropriate re-
straint system can be obtained from any
Mercedes-Benz Center. Infant and child restraint systems
Use only a BabySmart
TM1
compatible child
restraint for the front passenger seat in
this vehicle.
We recommend all infants and children be
properly restrained at all times while the
vehicle is in motion.
All lap-shoulder belts except the driver‘s
seat belt have special seat belt retractors
for secure fastening of child restraints.
To fasten a child restraint, follow child re-
straint instructions for mounting. Then pull
the shoulder belt out completely and let it
retract. During the seat belt retraction, a
ratcheting sound can be heard to indicate
that the special seat belt retractor is acti-
vated. The belt is now locked. Push down
on child restraint to take up any slack.
To deactivate, release seat belt buckle and
let seat belt retract completely. The seat
belt can again be used in the usual man-
ner.
Warning!
G
An emergency tensioning device (ETD) that
was activated must be replaced.
When disposing of the emergency tension-
ing device, our safety instructions must be
followed. These are available at your autho-
rized Mercedes-Benz Center.!Do not place objects heavier than
20 lbs (9kg) on the front passenger
seat. This could cause the front or side
impact airbag on the front passenger
side to deploy in a crash which exceeds
the system’s deployment threshold.

BabySmart
TM airbag deactivation
system Special BabySmart
TM compatible child
seats, designed for use with the
Mercedes-Benz system and available at
any authorized Mercedes-Benz Center are
required for use with the BabySmart
TM air-
bag deactivation system. With the special
child seat properly installed, the passenger
front airbag will not deploy.
The PASS. AIRBAG OFF indicator lamp lo-
cated in the center console will be illumi-
nated, except with the SmartKey removed
or in starter switch position 0.
Infants and small children should never
share a seat belt with another occupant.
During an accident, they could be crushed
between the occupant and seat belt.
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.
Children too big for child restraint systems
must ride in back seats using regular seat
belts. Position shoulder belt across chest
and shoulder, not face or neck. A booster
seat may be necessary to achieve proper
belt positioning for children from 41 lbs until
they reach a height where a lap/shoulder
belt fits properly without a booster.
When the child restraint is not in use, re-
m o v e i t f r o m t h e v e h i c l e o r s e c u r e i t w i t h t h e
seat belt to prevent the child restraint from
becoming a projectile in the event of an ac-
cident.
Do not leave children unattended in the ve-
hicle; even if the children are secured in a
child restraint system. Unsupervised chil-
dren in a child restraint system may use ve-
hicle equipment and may cause an accident
and/or serious personal injury.
iThe system does not deactivate the
side impact airbag and the emergency
tensioning device.
