On the passenger side, regard less of safety
be lt use, the airbag will be turned off if the
weight on the passenger seat is less than the
amo unt programmed in the electronic control
un it. The front airbag on the passenger side
w ill also be turned off if one of the child safe­
ty seats that has been certified under Federal
Motor Vehicle Safety Standard 208 has been
recog nized on the seat . The

_&. WARNING
To reduce the risk of injury when an airbag
inf lates, a lways wear safety belts properly.
- If you are unrestrained, lean ing forward,
sitting sideways or out of position in any
way, yo ur risk of inj ury is much higher.
- You w ill also receive serio us injuries and
cou ld even be killed if you are up against
the a irbag or too close to it when it in­
flates -even with an Advanced Airbag

front airbags
F ig. 2 11 Inflated front airbags
Safety belts are important to help keep front
seat occupants in the proper seated pos ition
so that airbags can unfo ld properly and pro ­
vide supplemental protection in a fronta l col­
l ision.
A irba g sy stem 193
The front airbags are designed to provide ad ­
ditional protection for the chest and face of
the driver and the front seat passenger when:
- safety belts are worn properly
- t he seats have bee n positioned so that the
occ upan t is properly seated as far as poss i­
b le from the airbag
- and the head restraints have been properly
adj usted
Because airbags inflate in the blink of an eye
with great force, t hings you have on your lap
or have placed on the seat co uld become dan­
gerous projecti les, and be p ushed in to you if
the a irbag inf lates.
When an airbag deploys, fine dust is re leased.
T his is no rma l and is not caused by a fi re in
the vehi cle. This dust is made up mos tly of a
powder used to lub ricate the airbags as they
deploy. It could irritate skin.
It is important to remembe r that wh ile the
s u pplementa l airbag system is designed to re­
duce the like lihood o f serious injuries, other
injuries, for example swelling, bruising and
minor abrasions, can a lso happen when air ­
bags inflate . A irbags do not protect the arms
or the lower parts of the body. Front airbags
supplement the th ree-point safety belts only
i n some frontal co llisions in which the vehicle
deceleration is high enough to deploy the air­
bags.
Front a irbags will not deploy :
-if the ignition is sw itched off when a crash
occurs
- in side collisions
- in rear-end co llisions
- in rollovers
- when the crash dece leration meas ured by
the air bag system is less than the minimum
threshold needed for airbag deployment as
reg istered by the electronic cont ro l unit
The front passenger airbag also will not
deploy:
- when the front passenger seat is not occu-
pied ..,.

inflates in side impacts and only when the ve­
hicle acceleration registered by the control
un it is high enough. If this rate is below the
reference value programmed into the contro l
unit, the side airbags will not be triggered,
even though the car may be badly damaged as
a result of the coll ision.
It is not possible to
define an airbag triggering range that will
cover eve ry possible angle of impact, since the
circumstances w ill vary considerably be tween
one co llision and another . Important factors
include, for examp le, the natu re (hard or soft)
of the impacting object, the angle of impact,
veh icle speed, etc. c::>
page 203, How side cur­
tain airbags work.
Aside from the ir normal safety function, safe ­
ty belts work to he lp keep the driver or front
passenger in posit ion in the event of a co lli­
sion so that the side curtain airbags can pro­
vide protection.
The airbag system is not a s ubstitute for your
safety belt. Rather, it is part of the overall oc­
cupant restraint system in your vehicle. Al­
ways remember that the airbag system can
only help to protect you if you are wearing
your safety belt and wear ing it prope rly. Thi s
i s another reason why you sho uld always wear
your safety bel ts, not just beca use the law re­
q ui res you to do soc::>

notes.
It is important to rememb er that while the
side curta in a irbag sys tem is designed to he lp
r educe the like lihood of se rious injur ies, other
in ju ries, for example, swell ing, bruising, and
minor abrasions can also be associated with
these airbags upon deployment. Remember
too, these a irbags w ill dep loy on ly once and
only in certain kinds of accidents - your safety be lts are a lways there to offer protection.

consi sts of:
- The electronic control mod ule and external

- The side curtain airbags above the front and rear side windows

- The airbag indicator light in the instrument
panel
T he airbag system is mon itored e lec tronically
to make ce rtain i t is func tioning prope rly at all
times . Each time you turn on the ignit ion, the
airbag system indicator light will come on for
a few seconds (self diagnostics).
The side curtain airbag i s not activat ed :
- if the ignition is turned off
- in side co llisions whe n the acceleration
measured by the sensor is too low
- in rea r-end collisions.
A WARNING
- Safety belts and the airbag system will
only provide pro te ction when occup ants
are in the proper seating posi tion
c::>
page 71, General recommendations.
- If th e air bag ind icator light comes on
when the vehicle is being used, have the
system inspected immediately by your
authorized A udi dealer . The side curtain
airbag may not work properly even when
the vehicle acce lerat ion in a side collision
is high enough to activate the airbag.
How side curtain airbags work
Side curtain airbags con work together with
side airbags to help reduce the risk of head
and upper torso injuries for occupants who
ore properly restrained.

A discharged batte ry can fre eze at tempera­
tures of on ly O
0C. Allow a frozen batte ry to
thaw comp lete ly before at tempting to charge
it ¢& . However, we recommend not using a
thawed battery again because the battery cas­
ing can be cracked due to ice formation and
can leak battery acid .
Battery charging (Ma ximum charging rate
of 30 amp s/14 .8 Volt)
When charging at low voltages (e.g . w ith a
tri ckle ch arger ), the battery cables do not
have to be d isconnected first. The battery
caps should
not be opened when charging a
battery .
It is not necessary to remove the battery from
the luggage compartment.
Fast chargin g the battery (ch arging rate
ab ove 14.8 V olt s)
For technical reasons do not use a battery
charger that uses voltage greater than 14.8
Volts to charge your vehicle's battery.
A WARNING
= -
Charging a battery can be dangerous .
-Always follow the operating instructions
provided by the battery charger manu­
facturer when charg ing your battery .
- Never charge a frozen battery. It may ex­
plode because of gas trapped in the ice.
Allow a frozen battery to thaw out f irst .
- Do not reuse batteries wh ich were fro­
zen. The battery housing may have
cracked and weakened when the battery
froze.
- Charge the battery in a well ventilated
area. Keep away from open flame or elec­
tr ica l spark. Do not smoke. Hydrogen gas
generated by the battery is explos ive .
- To reduce the danger of explosion, never
connect or d isconnect charger cab les
while the charger is ope rat ing .
- Fast cha rging a battery is dangerous and
should only be attempted by a compe­
tent techn ic ian with the proper equip­
ment .
- Battery acid that may sp ill dur ing cha rg­
ing should be washe d off wi th a solut ion
of wa rm water and baking soda to neu ­
tralize the ac id.

Neve r use a fast charger as a booster to
start the eng ine. Th is w ill seriously dam­
age sensit ive e lectronic components, such
