Adjusting
Adjusting
SeatsWarning!
G
All seat, steering wheel, and rear view mirror
adjustments, as well as fastening 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 in an excessively reclined position as
this can be dangerous. You could slide un-
der the seat belt in a collision. If you slide
under it, the seat belt would apply force at
the abdomen or neck. That could cause se-
rious or fatal injuries. The seat back and seat
belts provide the best restraint when the
wearer is in a nearly upright position and
seat belts are properly positioned on the
body.Warning!
G
Your seat must be adjusted so that you can
correctly fasten your seat belt (
page 45).
Observe the following points:


Adjust the seat to a comfortable seating
position that still allows you to reach the
accelerator/brake pedal safely. The po-
s i ti on s ho ul d be as fa r t o t he r ea r a s po s -
sible, consistent with ability to properly
operate controls.


Adjust the seat until a comfortable
steering wheel position is reached with
your arms slightly bent at the elbow.


Never place hands under the seat or
near any moving parts while a seat is
being adjusted.
Failure to do so 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 seats can be operated.
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.

Driving
Fastening the seat belts
Warning!
G
Make sure that absolutely no objects are ob-
structing the pedals’ 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
or 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 72).
Warning!
G
Children 12 years old and under must be
seated and properly secured in an appropri-
ately sized infant restraint, toddler restraint,
or booster seat recommended for the size
and weight of the child. For additional infor-
mation, see “Children in the vehicle”
(page 76).
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.

47 Getting started
Driving


Place the seat backrest in a nearly up-
right position.


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 that it is properly
positioned.


Make sure that the seat belt is always
fitted snugly. Take special care of this
when wearing loose clothing.
Starting the engine
Warning!
G
Do not pass 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.
Warning!
G
Inhalation of exhaust gas is hazardous to
your health. All exhaust gas contains carbon
monoxide (CO), and inhaling it can cause
unconsciousness and possible death.
Do not run the engine in confined areas
(such as garage) which are not properly
ventilated. If you think that exhaust gas
fumes are entering the vehicle while driving,
have the cause determined and corrected
immediately. If you must drive under these
conditions, drive only with at least one
window fully open.

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

63 Safety and Security
Occupant safety


Adjust the passenger seat as far as pos-
sible rearward from the dashboard when
the seat is occupied.


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 air bag be deployed. Always sit as
upright as possible, properly use the
seat belts and an appropriately sized in-
fant, or 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, prop-
erly use the seat belts, and for children
12 years old or under, use an appropri-
ately sized infant restraint, toddler re-
straint, 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 head-thorax air bag deactivated,
then deactivation can be accomplished
upon your written request 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.

If the PASSENGER AIR BAG OFF indicator
lamp illuminates when an adult or someone
larger than a small individual is in the pas-
senger seat, have the passenger re-position
himself or herself in the seat until the
PASSENGER AIR BAG OFF indicator lamp
goes out.
For information on air bag display
messages, see (
page 324).
In the event of a collision, the air bag control
unit will not allow passenger front air bag or
passenger knee air bag deployment when
the OCS classified the passenger seat occu-
pant 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 PASSENGER AIR BAG OFF indi-
cator lamp will illuminate when the engine is
started and remain illuminated, indicating
that the passenger front air bag and passen-
ger knee air bag are deactivated.
When the OCS senses that the passenger
seat is classified as being empty, the
PASSENGER AIR BAG OFF indicator lamp
will illuminate when the engine is started
and remain illuminated, indicating that the
passenger front air bag and the passenger
knee air bag are 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 PASSENGER
AIR BAG OFF 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
PASSENGER AIR BAG OFF indicator lamp
illuminated, the passenger front air bag and
the passenger knee air bag are deactivated.
With the PASSENGER AIR BAG OFF indicator
lamp out, the passenger front air bag and
the passenger knee air bag are activated.
When the OCS senses that the passenger
seat occupant is classified as an adult or
someone larger than a small individual, the

If the PASSENGER AIR BAG OFF indicator
lamp is illuminated, the passenger front air
bag and the passenger knee air bag are
deactivated and will not be deployed.
If the PASSENGER AIR BAG OFF indicator
lamp is not illuminated, the passenger front
air bag and the passenger knee air bag are
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 and the pas-
senger knee air bag are 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 and the passenger
knee air bag in your vehicle when the
system senses the weight of a typical
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 and/or the passenger knee
air bag inflate in a collision which could
occur under some circumstances, even
with the air bag technology installed in
your vehicle.


If you install a rear-facing child restraint
on the passenger seat, make sure that
the PASSENGER AIR BAG OFF indicator
lamp is illuminated, indicating that the
passenger front air bag and the passen-
ger knee air bag are deactivated. Should
the PASSENGER AIR BAG OFF indicator
lamp not illuminate or go out while the
restraint is installed, please check in-
stallation. Periodically check the
PASSENGER AIR BAG OFF indicator
lamp while driving to make sure the
PASSENGER AIR BAG OFF indicator
lamp is illuminated. If the PASSENGER
AIR BAG OFF indicator 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 injured or even killed if the
passenger front air bag and/or the
passenger knee air bag inflate.


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 and the passenger knee air bag
may or may not be activated
(page 68).
i
Deployment of the driver front air bag does
not mean that the passenger front air bag also
should have deployed.
The Occupant Classification System (
page 67)
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

Seat belts
The use of seat belts and infant and child
restraint systems is required by law in all
50 states, the District of Columbia, the
U.S. territories and all Canadian provinces.
Even where this is not the case, all vehicle
occupants should have their seat belts fas-
tened when ever the vehicle is in motion.
For information on fastening seat belts,
see “Fastening the seat belts” (
page 45).
Warning!
G
If the PASSENGER AIR BAG OFF indicator
lamp should not illuminate, the system is
not functioning. You must contact an autho-
rized Mercedes-Benz Center before seating
any child on the passenger seat.Warning!
G
Never place anything between seat
cushion and child seat (e.g. pillow), since it
reduces the effectiveness of the Occupant
Classification System. The bottom of the
child seat must make full contact with the
passenger seat cushion. An incorrectly
mounted child seat could cause injuries to
the child in case of an accident, instead of
increasing protection for the child.
Follow the manufacturer’s instructions for
installation of child seats.
i
For information on infants and children trav-
eling with you in the vehicle and restraint sys-
tems for infants and children, see “Children in
the vehicle” (
page 76).
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 po-
sition 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. Air bags can only protect as they
are designed if the occupants are properly
wearing their seat belts.

74 Safety and SecurityOccupant safety
Enhanced seat belt reminder system
When the engine is started, the seat belt
telltale< will always illuminate
for 6 seconds to remind you and your
passenger to fasten your seat belts.
If the driver’s seat belt is not fastened
when the engine is started, an additional
warning chime will also sound for a maxi-
mum of 6 seconds or until the driver’s seat
belt is fastened.
If after these 6 seconds, the driver’s or the
passenger’s seat belt (with the passenger
seat occupied) are not fastened with all
doors closed,

the seat belt telltale< remains illu-
minated for as long as either the
driver’s or passenger’s seat belt is not
fastened.


Never wear the shoulder belt under your
arm, against your neck or off your shoul-
der. In a frontal crash, your body would
move too far forward. That would in-
crease the chance of head and neck in-
juries. The belt would also apply too
much force to the ribs or abdomen,
which could severely injure internal
organs such as your liver or spleen.


Never wear belts over rigid or breakable
objects in or on your clothing, such as
eyeglasses, pens, keys, etc., as these
might cause injuries.


Position the lap belt as low as possible
on your hips and not across the abdo-
men. If the belt is positioned across your
abdomen, it could cause serious person-
al injuries in a crash.


Never use a seat belt for more than one
person at a time. Do not fasten a seat
belt around a person and another per-
son or other objects.


Seat belts should not be worn twisted.
In a crash, you wouldn’t have the full
width of the seat belt to manage impact
forces. The twisted seat belt against
your body could cause injuries.


Pregnant women should also always use
a lap-shoulder belt. The lap belt portion
should be positioned as low as possible
on the hips to avoid any possible
pressure on the abdomen.


Never place your feet on the instrument
panel, dashboard or on the seat. Always
keep both feet on the floor in front of the
seat.


When using a seat belt to secure infant
or toddler restraints or children in
booster seats, always follow the child
seat manufacturer’s instructions.
