66 Safety and SecurityOccupant safetyIn this section you will learn the most
important facts about the restraint system
components of the vehicle.

Front passenger seat with Occupant
Classification System (OCS)
(page 81)
As 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 early detection of malfunctions.
The
1
indicator lamp in the instrument
cluster lights up 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
1
indicator lamp is not
lit when the engine is running.
A malfunction in the system has been
detected if the
1
indicator 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

72 Safety and SecurityOccupant safetyThe air bags will not deploy in impacts
which do not exceed the system’s deploy-
ment thresholds. You will then be protect-
ed by the fastened seat belts.The passenger front air bag will only be
deployed if:
the system, based on OCS weight sen-
sor readings, senses that the front pas-
senger seat is occupied
the 75 indicator lamp in the
center console is not lit (
page 85)
the impact exceeds a preset deploy-
ment threshold
Side impact air bags, window curtain
air bags
1Side impact air bags
2Window curtain air bagThe side impact air bags1 and window
curtain air bags2 are deployed:
on the impacted side of the vehicle
in impacts exceeding a preset deploy-
ment threshold
independently of the front air bags
In addition, the window curtain air bags 2
are deployed:
in certain vehicle rollovers
The side impact air bags1 and window
curtain air bags2 are not deployed in im-
pacts which do not exceed the system’s
deployment threshold.
iThe front air bags in this vehicle have
been designed to inflate in two stages.
This allows the air bag to have different
rates of inflation that are based on the
rate of relevant vehicle deceleration as
assessed by the air bag control unit.
On the front passenger side, the front
air bag deployment is additionally influ-
enced by the passenger’s weight cate-
gory as identified by the Occupant
Classification System (OCS)
(page 81).
The lighter the front passenger side oc-
cupant, the higher the vehicle deceler-
ation rate required for the second
stage inflation of the air bag.
80 Safety and SecurityOccupant safety
If you must install a rear-facing child re-
straint on the front passenger seat be-
cause circumstances require you to do
so, make sure that the
75indicator lamp is illuminat-
ed, indicating that the front passenger
air bag is deactivated. Should the light
not illuminate or go out while the re-
straint is installed, please check installa-
tion. Periodically check the indicator
lamp while driving to make sure the
lamp is illuminated. If the
75indicator lamp goes out or
remains out, do not transport a child on
the front passenger seat until the sys-
tem has been repaired. A child in a
rear-facing child restraint on the front
passenger seat will be seriously injured
or even killed if the front passenger front
air bag inflates.
If you have to place a child in a
forward-facing child restraint on the
front passenger seat, move the seat as
far back as possible, use the proper
child restraint recommended for the
age, size and weight of the child, and se-
cure 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 front passenger
air bag may or may not be activated
(page 82).
Warning!
G
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 a toddler restraint must
ride in seats using regular seat belts. Posi-
tion shoulder belt across chest and shoul-
der, 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 proper-
ly without a booster.
82 Safety and SecurityOccupant safetyWarning!
G
If the 75 indicator lamp illumi-
nates when an adult or someone larger than
a small individual is in the front passenger
seat, have the front passenger re-position
himself or herself in the seat until the light
goes out, or check whether objects are
caught under or around the seat.
More information about air bag display mes-
sages (
page 393).
In the event of a collision, the air bag control
unit will not allow front passenger front
air bag deployment when the OCS classified
the front passenger seat occupant as being
up to or less than the weight of a typical
12-month-old child in a standard child re-
straint or if the front passenger seat is
sensed as being empty.
When the OCS senses that the front passen-
ger seat occupant is classified as being up
to or less than the weight of a typical
12-month-old child in a standard child re-
straint, the 75 indicator lamp will
illuminate when the engine is started and re-
main illuminated, indicating that the front
passenger front air bag is deactivated.
When the OCS senses that the front passen-
ger seat is classified as being empty, the
75 indicator lamp will illuminate
when the engine is started and remain illu-
minated, indicating that the front passenger
front air bag is deactivated.
When the OCS senses that the front passen-
ger 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 oc-
cupant weight sensor readings from the
seat, remain illuminated or go out. With the
75 indicator lamp illuminated, the
front passenger front air bag is deactivated.
With the 75 indicator lamp out,
the front passenger front air bag is activat-
ed.
When the OCS senses that the front passen-
g e r s e a t o c c u p a n t i s c l a s s i f i e d a s a n a d u l t o r
someone larger than a small individual, the
75 indicator lamp will illuminate
for approximately 6 seconds when the en-
gine is started and then go out, indicating
that the front passenger front air bag is acti-
vated.
