Knee airbags
Description of knee airbags
The knee airbag system can provide supple­
mental protection to properly restrained
front seat occupants.
F ig . 11 4 Drive r's a irbag
The driver knee a irbag is in the instrument
panel underneath the steering whee l
~ fig. 114, the airbag for the passenger is at
about the same height in the i nstrument pan­
e l underneath the g love compartment.
The knee airbag offers additiona l protection
to the driver's and passenger's knees and up­
per and lower thigh areas and supp lements
the protect ion by the safety be lts .
I f the front airbags deploy, the knee airbags
a lso deploy i n frontal collisions when the de­
p loyment threshold sto red in the cont ro l uni t
is met ~
page 117, More important things to
know about front airbags .
In addition to their normal safety function,
safety belts he lp keep the driver or front pas ­
senger in posit ion in a frontal coll is ion so that
A irba g sy stem 123
the ai rbags can provide supplemental protec­
tion .
T he airbag system is no t a subs tit ute for your
sa fety be lt . Rather, it is part of the overall oc­
cupant restraint system in your vehicle . A l­
ways remember that the airbag system can
only he lp to protect you if you are wearing
your safety be lt and wearing it properly. This
is why you should always wear your safety
belt, not just because the law requires you to
do so
r::;, page 100, General notes .
Remember too, airbags will deploy on ly once
and only in certain kinds of accidents -your
safety belts are always there to offer protec­
t ion in those accidents in wh ich airbags are
not supposed to dep loy o r when they have al­
r eady deployed, for example when your vehi ­
cl e strikes or is struck by another after the
f irst collision.
This is just one of the reasons why an airbag is
not a s ubstitute fo r the safety be lt. The ai rbag
system works most effect ively when used with
the safety be lts. Therefore, always wear yo ur
sa fety belts correct ly .
It is impo rtant to remembe r that wh ile the
s u pplementa l knee airbag system is designed
to reduce the likelihood of ser ious inju ries,
other injur ies, for example, swelling, bru ising,
minor ab rasions and friction burns can a lso
occur when an airbag inflates.
The knee airbag system basically consists
of:
- The e lectronic control module
- Two in flatable ai rbags (a irbag and gas gen -
erator), one for the d river and one for the
front passenger
- The ai rbag indicator light in the instrument
panel
The knee airbag system will not deploy:
- when the ignit io n is t urned off
- in frontal collisions when the deceleration
meas ured by the control unit is too low
- in side co llisions
- in rear-end collisions
- in rollovers

ing/indicator light is on )

.&_ WARNING
-Safety belts and the airbag system can
only provide protection when occupants
are in the proper seating position
¢page 117.
-If the airbag indicator light comes when
the vehicle is being used, have the sys­
tem inspected immediately by your au­
tho rized Aud i deale r.
How knee airbags work
The risk of injury to the leg area can be re­
duced by fully inflated knee airbags.
F ig . 115 Inflated a irbags p rotecti ng in a fro ntal coll i­
s ion
The knee airbag system has been designed so
that the airbags for the driver and front pas­
senger deploy in certain but not all frontal
coll is ions.
If the front airbags deploy, the knee airbags
also deploy in frontal collisions when the de­ p loyment threshold stored in the control unit
i s met.
When the system dep loys, the airbags fill
with a propellant gas, and inflate between the lower part of the instrument panel and the
d river and the lower part of the instrument
panel and the front passenge r<=>
page 117,
fig. 112.
Although they are not a soft pillow, they can
"cush ion" the impact and in this way they can
he lp to reduce the r isk of injury to the lowe r
extremities. All o
f th is takes place in the b link o f an eye, so
fast that many peop le don't even realize that
the a irbags have deployed. The airbags a lso
inflate with a great deal of force and it is im­
portant for occupant safety that nothing
shou ld be in their way when they deploy.
Fully inflated a irbags in combination with
proper ly worn safety belts s low down and lim­
it the occupant's forward movement and help
to reduce the risk of injury .
Important safety instructions on the
knee airbag system
Airbags are only supplemental restraints . Al­
ways wear safety belts correctly and ride in a
proper seating position.
The re is a lot that you and you r passenger
must know and do to he lp the safety belts and
airbags to prov ide s upplemen ta l pro te ct io n .
.&_ WARNING
An inflat ing knee a irbag c an cause se rious
in ju ry. Wea ring safety belts incorrectly and
improper seat ing positions increase the
risk of ser ious persona l injury and death
whenever a vehicle is being used.
- The knee airbag system cannot protect
you properly if you a re seated too close
to any of the airbag locat ions. When ad­
justing their seat pos itions, it is impor­
tant that bot h the driver and the front
passenger keep the ir upper bod ies and
knees at the following minimum safe
d istances:
- at least 10 inches (25 cm) between the
chest and the steering wheel/inst ru­
ment panel.
- at least 4 inches (10 cm) between the
knees and the lower part of the instru­
ment panel.
- The risk of personal inj ury increases if
you lean forward or to the s ide, or if the
seat is improperly positioned and you are
not wearing yo ur safety belt . The risk in­
creases even more should the a irbag de­
p loy .

-Always make sure that the knee airbag
can inflate without interference. Objects
between you and the airbag can increase
the risk of injury in an accident by inter­
fering with the way the airbag deploys or by being pushed into you as the airbag
deploys.
- Never let anybody, especially children
or animals ride in the footwell in front
of the passenger seat.
If the airbag de­
ploys, this can result in serious or fatal
injuries.
- Never carry objects of any kind in the
footwell area in front of the driver's or passenger's seat. Bulky objects (shop­
ping bags, for example) can interfere
with or prevent proper deployment of
the airbag. Small objects can be
thrown through the vehicle if the air­
bag deploys and injure you or your pas­
sengers.
- Make sure there are no cracks, deep
scratches or other damage in the area of
the instrument panel where the knee air­
bags are located.
- If children are incorrectly seated, their
risk of injury increases in a collision

Side airbags
Description of side airbags
The airbag system can provide supplemental
protection to properly restrained front seat occupants.
Fig . 116 Side airbag location in the driver 's seat
The s ide airbags are located in the sides of the
front seat backrests
¢ fig. 116facing the
Airbag system 125
doors. They are identified by the word "AIR­
BAG".
The side airbag system basically consists of:
- the electron ic control module and external
side impact sensors
- the two side airbags located in the sides of the front backrests
- the airbag warning light in the instrument
cluster.
The airbag system is monitored electronically
to make certain that it is functioni ng properly
at all times. Each time you turn on the igni­
tion, the airbag system indicator light will
come on for a few seconds (self diagnostics).
The side airbag system supplements the safe­
ty belts and can help to reduce the risk of in­
jury to the driver's and front passenger's up ­
per torso on the s ide of the vehicle that is
struck in a side collision. The airbag deploys in
side impacts and only when the vehicle accel­
eration registered by the control unit is high
enough. If this rate is below the reference val­
ue programmed into the control unit, the side
airbags will not be triggered, even though the
car may be badly damaged as a result of the
collision . It is not possible to define an airbag
triggering range that will cover every possible
angle of impact, since the circumstances will
vary considerably between one collision and
another. Important factors include, for exam­
ple, the nature (hard or soft) of the impacting
object, the angle of impact, vehicle speed,
etc.
¢ page 127, Important safety instruc­
tions on the side airbag system .
Aside from their normal safety function, safe­
ty belts work to help keep the driver or front
passenger in position in the event of a side
collision so that the side airbags can provide
protection.
The airbag system is
not a substitute for your
safety belt. Rather, it is part of the overall oc­
cupant restraint system in your vehicle. Al­
ways remember that the side airbag system
can only help to protect you if you are wearing
your safety belt and wearing it properly. This is another reason why you should always wear

130 Child Safety
8_ WARNING
If, in exceptional circumstances, you must
install a forward-facing child restraint on
the front passenger's seat:
- Always make sure the forward-facing
seat has been designed and certified by
its manufacturer for use on a front seat
with a passenger front and side airbag.
-Always follow the manufacturer's in­
structions provided with the child safety
seat or carrier.
-Always move the passenger seat into its
rearmost position in the seat's fore and
aft adjustment range, as far away from
the airbag as possible before installing
the child restraint. The backrest must be adjusted to an upright position.
- Always make sure that the
PASSENGER
AIR BAG OFF
light comes on and stays
on all the time whenever the ignition is
switched on.
(D Tips
Always replace child restraints that were
installed in a vehicle during a crash. Dam­
age to a child restraint that is not visible
could cause it to fail in another collision
situation.
Advanced front airbag system and children
Your vehicle is equipped with an "Advanced
Airbag System" in compliance with United
States Federal Motor Vehicle Safety Standard
(FMVSS) 208 as applicable at the time your
vehicle was manufactured.
The Advanced Airbag system in your vehicle
has been certified to meet the "low-risk " re­
quirements for 3- and 6-year old children on
the passenger side and small adults on the
driver side. The low risk deployment criteria
are intended to reduce the risk of injury
through interaction with the airbag that can
occur, for example, by being too close to the
steering wheel and instrument panel when
the airbag inflates. In addition , the system has been certified to comply with the "sup­
pression" requirements of the Safety Stand­
ard, to turn off the front airbag for infants up
to 12 months who are restrained on the front
passenger seat in child restraints that are list­
ed in the Standard.
Even though your vehicle is equipped with an
Advanced Airbag system, a child should al­
ways ride in the seat properly restrained for
its age and size. The airbag on the passenger
side makes the front seat a potentially dan­
gerous place for a child to ride. The front seat
is not the safest place for a child in a forward­
facing child safety seat. It can be a very dan­
gerous place for an infant or a larger child in a
rearward-facing seat.
Advanced Airbags and the weight­
sensing mat in the front seat
The Advanced Airbag System in your vehicle
detects the presence of an infant or child in a
child restraint on the front passenger seat us­
ing the weight-sensing mat in the seat cush­
ion and the sensor below the safety belt latch
on the front passenger seat that measures the
tension on the safety belt.
The weight-sensing mat measures total
weight of the child and the child safety seat
and a child blanket on the front passenger
seat. The weight on the front passenger seat
is related to the design of the child restraint
and its "footprint", the size and shape of the
bottom of the child restraint as it sits on the
seat. The weight of a child restraint and its
"footprint" vary for different kinds of child re­
straints and for the different models of the
same kind of child restraint offered by child
restraint manufacturers.
The weight ranges for the individual types,
makes and models of child restraints that the
NHTSA has specified in the Safety Standard
together with the weight ranges of typical in­
fants and typical 1 year-old child have been
stored in the control unit of the Advanced Air­
bag System. When a child restraint is being
used on the front passenger seat with a .,..
