Warning!
Work improperly carried out on electronic
components and associated software could
cause them

to cease functioning. Because the
vehicle’s electronic components are
interconnected, any modifications made may
produce an undesired effect on other
systems. Electronic malfunctions could
seriously impair the operating safety of your
vehicle.
Contact an authorized Mercedes-Benz Center
for repairs or modifications to electronic
components.
Other improper work or modifications on the
vehicle could also have a negative impact on
the operating safety of the vehicle.
Some safety systems only function while the
engine is running. You should therefore never
turn off the engine while driving. G
Warning!
Heavy blows against the vehicle underbody or
tires/wheels may cause serious damage and
impair the operating safety of your vehicle.
Such blows can be caused, for example, by
running over an obstacle, road debris or a
pothole. If you feel a sudden significant
vibration or ride disturbance, or you suspect
that damage to your vehicle as occurred:
R turn on your hazard warning flashers
R slow down carefully
R drive with

caution to an area which is a safe
distance from the road
Inspect the vehicle underbody and tires/
wheels for possible damage. If the vehicle
appears unsafe, have it towed to the nearest
authorized Mercedes-Benz Center or other
qualified maintenance or repair facility for
further inspection or repairs. 22

R
Adjust the front passenger seat as far as
possible rearward from the dashboard
when the seat is occupied.
R Occupants, especially children, should
never place
their bodies or lean their heads
in the area of the door where the side
impact air bag inflates. This could result in
serious injuries or death should the side
impact air bag be deployed. Always sit as
upright as possible, wear the seat belt
properly and use an appropriately sized
infant restraint, toddler restraint, or
booster seat recommended for the size and
weight of the child.
Failure to follow these instructions can result
in severe injuries to you or other occupants.
If you sell your vehicle, it is important that you
make the buyer aware of this safety
information. Be sure to give the buyer this
Operator’s Manual. G
Warning!
Accident research shows that the safest place
for children

in an automobile is in a rear seat.
There is a possibility for a side impact air bag-
related injury if occupants, especially
children, are not properly seated or restrained
when next to a side impact air bag which
needs to deploy rapidly in a side impact in
order to do its job.
To help avoid the possibility of injury, please
follow these guidelines:
(1) Occupants, especially children, should never
place their bodies or
lean their heads in the area of the
door where the side impact air bag
inflates. This could result in
serious injuries or death should
the side impact air bag be
deployed.
(2) Always sit as upright as possible, wear the
seat belt properly and use
an appropriately sized infant
restraint, toddler restraint, or
booster seat recommended for the size and weight of the child. and
for children 12 years old and
under, use an appropriately sized
infant restraint, toddler restraint,
or booster seat recommended for
the size and weight of the child.
(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 the rear mounted side
impact air bags deactivated, then
deactivation can be carried out upon your
written request at an authorized Mercedes-
Benz Center at an additional cost.
Please contact an authorized Mercedes-Benz
Center or call the Customer Assistance
Center (in the USA) at 1-800-FOR-MERCedes
(1-800-367-6372), or Customer Service (in
Canada) at 1-800-387-0100 for details.
Air bags are designed to deploy only in certain
R frontal impacts (front air bags and driver’s
side knee bag)
R side impacts (side impact and window
curtain air bags) if the system determines
the need for air bag deployment
R rollovers (window curtain air bags)
Only in the event of such a situation will they
provide their supplemental protection.
The driver and passengers should always
wear their seat belts. Otherwise it is not
possible for the air bags to provide their
supplemental protection.
In case of other types of impacts and impacts
below air bag deployment thresholds, air
bags will not deploy. The driver and
passengers will then be protected to the
extent possible by a properly fastened seat
belt. A properly fastened seat belt is also
needed to provide the best possible
protection in a rollover.
Air bags are not a substitute for seat belts.
Always wear your seat belt, regardless of
whether or not your vehicle is equipped with
air bags. 38

If the occupant’s weight is transferred to
another object in the vehicle (e.g. by leaning
on armrests), the OCS may not be able to
properly approximate the occupant’s weight
category.
If your seat, including the trim cover and
cushion, needs to be serviced in any way, take
the vehicle to an authorized Mercedes-Benz
Center.
Only seat accessories approved by
Mercedes-Benz may be used.
Both the driver and the front passenger
should always use the 42
indicator lamp as an indication of whether or
not the front passenger is properly
positioned. G
Warning!
If the 42 indicator lamp
illuminates when an adult or someone larger
than a small individual is in the front
passenger seat, have the front passenger
reposition himself or herself in the seat until
the 42 indicator lamp goes out.
In the event of a collision, the air bag control
unit will

not allow front passenger front air bag
deployment when the OCS has classified the
front passenger seat occupant as weighting
as much as or less than a typical 12-month-
old child in a standard child restraint or if the
front passenger seat is classified as being
empty. When the OCS senses that the front
passenger seat occupant is classified as
being
up

to or less than the weight of a typical
12-month-old child in a standard child
restraint, the 42 indicator lamp
will illuminate when the engine is started and
remain illuminated, indicating that the front
passenger front air bag is deactivated.
When the OCS senses that the front
passenger seat is classified as being empty,
the 42 indicator lamp will
illuminate when the engine is started and
remain illuminated, indicating that the front
passenger front air bag is deactivated.
When the OCS senses that the front
passenger seat occupant is classified as
being heavier than the weight of a typical
12-month-old child seated in a standard child
restraint or as being a small individual (such
as a young teenager or a small adult), the
42 indicator lamp will illuminate
for approximately 6 seconds when the engine
is started and then, depending on occupant
weight sensor readings from the seat, remain
illuminated or go out. With the
42 indicator lamp illuminated,
the front passenger front air bag is
deactivated. With the 42
indicator lamp out, the front passenger front
air bag is activated.
When the OCS senses that the front
passenger seat occupant is classified as an
adult or someone larger than a small
individual, the 42 indicator lamp
will illuminate for approximately 6 seconds
when the engine is started and then go out,
indicating that the front passenger front air
bag is activated.
If the 42 indicator lamp is
illuminated, the front passenger front air bag
is deactivated and will not be deployed. 42
