Warning!

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.

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).

Occupant safety
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 door 
mounted side airbags deactivated, then de-
activation 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), 
side impacts (side impact and head 
protection window curtain airbags) 
which exceed preset thresholds, and in 
certain rollovers (head protection win-
dow curtain airbags). Only during these 
events will they provide their supple-
mental protection.
The driver and passengers should al-
ways wear their seat belts. Otherwise it 
is not possible for the airbags to pro-
vide their supplemental protection.
In cases of other types of impacts and 
impacts below airbag deployment 
thresholds, the airbags will not be acti-
vated. The driver and passengers will 
then be protected to the extent possi-
ble by a properly fastened seat belt. A 
properly fastened seat belt is also 
needed to provide the best possible 
protection in a rollover.
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 
for 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 supplemental crash protec-
tion for occupants.

Never release the seat belt buckle while the 
vehicle is in motion, since the special seat 
belt retractor will be deactivated.!The use of infant or child restraints is 
required by law in all 50 states, the Dis-
trict of Columbia, the U.S. territories, 
and all Canadian provinces.
Infants and small children should be 
seated in an appropriate infant or child 
restraint system properly secured by a 
lap-shoulder belt or, if so equipped, a 
child restraint lower anchorage system 
that complies with U.S. Federal Motor 
Vehicle Safety Standards 213 and 225 
and Canadian Motor Vehicle Safety 
Standards 213 and 210.2.
A statement by the child restraint man-
ufacturer of compliance with this stan-
dard can be found on the instruction 
label on the restraint and in the instruc-
tion manual provided with the restraint.
When using any infant or child restraint 
system, be sure to carefully read and 
follow all manufacturer’s instructions 
for installation and use.
Please read and observe warning labels 
affixed to inside of vehicle and to infant 
or child restraints.

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.
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. un-
til they reach a height where a lap/shoulder 
belt fits properly without a booster.
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.
When the child restraint is not in use, re-
move it from the vehicle or secure it with the 
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 or the emergency 
tensioning device.
