mains on after starting the engine or
comes on while driving, see “Lamps in
instrument cluster” (
page 346).
3Starting position
iWithout the antenna on the left rear side
of the vehicle installed, the SmartKey signaling
range is considerably reduced.
Hold the SmartKey in close proximity towards
the antenna base when locking or unlocking
the vehicle.
Warning!G
When leaving the vehicle, always remove the
SmartKey from the starter switch, take it
with you, and lock the vehicle. Do not leave
children unattended in the vehicle, or with
access to an unlocked vehicle.
A child’s unsupervised access to a vehicle
could result in an accident and/or serious
personal injury.

Warning!G
When leaving the vehicle, always remove the
SmartKey from the starter switch, take it
with you, and lock the vehicle.
Even with the SmartKey removed from the
starter switch, the power seats* can be op-
erated when the respective door is open.
Therefore, do not leave children unattended
in the vehicle, or with access to an unlocked
vehicle. A child’s unsupervised access to a
vehicle could result in an accident and/or
serious personal injury.
Warning!G
Children 12 years old and under must be
seated and properly secured in an appropri-
ate infant, or toddler restraint, or booster
seat recommended for the size and weight
of the child. For additional information, see
“Children in the vehicle” (
page 79).
A child’s risk of serious or fatal injuries is
significantly increased if the child restraints
are not properly secured in the vehicle
and/or the child is not properly secured in
the child restraint.
!When moving the seats, make sure there are
no items in the footwell or behind the seats;
otherwise you could damage the seats.

48 Getting started
Driving
Fastening the seat belts
Warning!G
Make sure that absolutely no objects are ob-
structing the pedal’s range of movement.
Keep the driver’s footwell clear of all obsta-
cles. If there are any floormats or carpets in
the footwell, make sure the pedals still have
sufficient clearance.
During sudden driving or braking maneu-
vers, the objects could get caught between
the pedals. You could then no longer brake
or accelerate. This could lead to accidents
and injury.Warning!G
Always fasten your seat belt before driving
off. Always make sure your passenger is
properly restrained.
Failure to wear and properly fasten and
position your seat belt greatly increases
your risk of injuries and their likely severity
in an accident. You and your passenger
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 air bags can only provide the
protection they were designed to afford if
the occupants are using their seat belts
(
page 64).
Warning!G
Children 12 years old and under must be
seated and properly secured in an appropri-
ate infant, or toddler restraint, or booster
seat recommended for the size and weight
of the child. For additional information, see
“Children in the vehicle” (
page 79).
A child’s risk of serious or fatal injuries is
significantly increased if the child restraints
are not properly secured in the vehicle
and/or the child is not properly secured in
the child restraint.

50 Getting started
Driving
Proper use of seat belts

Do not twist the seat belt when
fastening.

Adjust seat belt so that the shoulder
portion is located as close as possible
to the middle of the shoulder (it should
not touch the neck). Never pass the
shoulder portion of the seat belt under
your arm.

Position the lap belt as low as possible
on your hips (over hip joint) and not
across the abdomen.

Place the seat backrest in a position
that is as upright as possible.

Never use a seat belt for more than one
person at a time.

Do not fasten a seat belt around a per-
son and another object at the same
time. When using a seat belt to secure
infant or toddler restraints or children
in booster seats, always follow the
child seat manufacturer’s instructions.

Check your seat belt during travel to
make sure it is properly positioned.

Make sure the seat belt is always fitted
snugly. Take special care of this when
wearing loose clothing.
Warning!G
Do not pass seat belts over sharp edges.
They could tear.
Do not allow the seat belt to get caught in
the door or in the seat adjustment mecha-
nism. This could damage the seat belt.
Never attempt to make modifications to
seat belts. This could impair the effective-
ness of the seat belts.
Do not bleach or dye seat belts as this may
severely weaken them. In a crash, they may
not be able to provide adequate protection.
Damaged seat belts or seat belts that were
highly stressed in an accident must be
replaced. Contact an authorized
Mercedes-Benz Center.

Although independent systems, their
protective functions work in conjunction
with each other.The SRS system conducts a self-test when
the ignition is switched on and in regular
intervals while the engine is running. This
facilitates detection of malfunctions. The
1indicator lamp in the instrument
cluster comes on when the ignition is
switched on and goes out no later than a
few seconds after the engine has been
started.
The SRS components are in operational
readiness if the 1indicator lamp is not
lit when the engine is running.
A malfunction in the system has been
detected if the 1indicator lamp:

fails to go out after approximately
4 seconds after the engine was started

does not come on at all

comes on after the engine was started
or while driving

67 Safety and Security
Occupant safety

Occupants, especially children, should
always sit as upright as possible, proper-
ly use the seat belts and use an appro-
priately 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.Warning!G
There is a possibility of a head-thorax air bag
related injury if occupants, especially chil-
dren, are not properly seated or restrained
when next to a head-thorax 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
head-thorax air bag inflates. This could
result in serious injuries or death should
the head-thorax air bag be deployed.
(2) Always sit as upright as possible,
properly use the seat belts, and for all
children 12 years old or 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
passenger seat occupants to have the pas-
senger side head-thorax air bag deactivated,
then deactivation can be accomplished
upon your written election to do so at an
authorized Mercedes-Benz Center at an
additional cost.
Please contact your local 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.

72 Safety and Security
Occupant safety
Warning!G
If the 75 indicator lamp illumi-
nates when an adult or someone larger than
a small individual is in the passenger seat,
have the passenger re-position himself or
herself in the seat until the 75
indicator lamp goes out.
More information about air bag display
messages (
page 361).
In the event of a collision, the air bag control
unit will not allow passenger front air bag
deployment when the OCS classified the
passenger seat occupant as being up to or
less than the weight of a typical
12-month-old child in a standard child
restraint or if the passenger seat is sensed
as being empty.
When the OCS senses that the 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 75 indicator lamp
will illuminate when the engine is started
and remain illuminated, indicating that the
passenger front air bag is deactivated.
When the OCS senses that the passenger
seat is classified as being empty, the
75 indicator lamp will illumi-
nate when the engine is started and remain
illuminated, indicating that the passenger
front air bag is deactivated. When the OCS senses that the 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
75 indicator lamp will illumi-
nate 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
75 indicator lamp illuminated,
the passenger front air bag is deactivated.
With the 75 indicator lamp out,
the passenger front air bag is activated.
When the OCS senses that the passenger
seat occupant is classified as an adult or
someone larger than a small individual, the
75 indicator lamp will illumi-
nate for approximately 6 seconds when the
engine is started and then go out, indicating
that the passenger front air bag is activated.

73 Safety and Security
Occupant safety
If the 75 indicator lamp is
illuminated, the passenger front air bag is
deactivated and will not be deployed.
If the 75 indicator lamp is not
illuminated, the passenger front air bag is
activated and will be deployed:

in the event of certain frontal impacts

if impact exceeds a preset deployment
threshold

independently of the head-thorax air
bags
If the passenger front air bag is deployed,
the rate of inflation will be influenced by:

the rate of relevant vehicle deceleration
as assessed by the air bag control unit

passenger’s weight category as identi-
fied by the Occupant Classification
System (OCS)
Warning!G
Children 12 years old and under must be
seated and properly secured in an appropri-
ate infant or child restraint recommended
for the size and weight of the child.
The infant or child restraint must be properly
secured with the vehicle’s seat belt fully in
accordance with the child seat manufactur-
er's instructions.
Children can be killed or seriously injured by
an inflating air bag. Note the following
important information:

Your vehicle is equipped with air bag
technology designed to turn off the pas-
senger front air bag in your vehicle when
the system senses the weight of a typi-
cal 12-month-old child or less along with
the weight of a standard appropriate
child restraint on the passenger seat.

A child in a rear-facing child restraint on
the passenger seat will be seriously
injured or even killed if the passenger
front air bag inflates in a collision which
could occur under some circumstances,
even with the air bag technology in-
stalled in your vehicle.

If you install a rear-facing child restraint
on the passenger seat, make sure that
the 75indicator lamp is
illuminated, indicating that the passen-
ger front air bag is deactivated. Should
the 75 indicator lamp not
illuminate or go out while the restraint is
installed, please check installation.
Periodically check the 75
indicator lamp while driving to make
sure the 75 indicator lamp
is illuminated. If the 75 in-
dicator lamp goes out or remains out, do
not transport a child on the passenger
seat until the system has been repaired.
A child in a rear-facing child restraint on
the passenger seat will be seriously in-
jured or even killed if the passenger
front air bag inflates.


74 Safety and Security
Occupant safety
The 75indicator lamp is
located in the center console.
1Passenger front air bag off indicator
lamp
The 75indicator lamp1 will
be illuminated, except with the SmartKey
removed or in starter switch position0.
If you place a child in a forward-facing
child restraint on the passenger seat,
move the seat as far back as possible,
use the proper child restraint recom-
mended for the age, size and weight of
the child, and secure child restraint with
the vehicle’s seat belt according to the
child seat manufacturer’s instructions.
For children larger than the typical
12-month-old child, the passenger front
air bag may or may not be activated
(
page 72).
iDeployment of the driver front air bag does
not mean that the passenger front air bag also
should have deployed.
The Occupant Classification System (
page 71)
may have determined:

that the seat was empty or occupied by the
weight up to or less than that of a typical
12-month-old child seated in a standard
child restraint – both instances where the
system suppresses deployment of the
passenger front air bag even though the
impact met the criteria and was of sufficient
severity to deploy the driver front air bag.

that the seat was occupied by a small individ-
ual (such as a young teenager or a small
adult) or a child weighing more than the
weight of a typical 12-month-old child in a
standard child restraint – instances where
the system may suppress deployment of the
passenger front air bag even though the
impact met the criteria and was of sufficient
severity to deploy the driver front air bag.
