Side curtain airbags
Description of curtain airbags
The curtain airbags can provide supplemental protection
to properly restrained occupants.
F ig . 1 42 C urtain
a irb ag, dr iver 's side:
s ide c urt ain ai rbag
loc ation
The side curtain airbags are located on bot h sides of t he interior
a b ove the fro nt an d rear side windows ~ fig. 1 42. T hey ar e identified
by the word "AIRBAG" on t he w indshield frame and the center roo f
pillar .
Th e side curtain a irbag system supplements t he safety belts and ca n
help to reduce the risk of injury for occupants' heads and upper torso
on t he side of the vehi cle th at i s st ru ck in a s ide collision. The s ide
curtain airbag inflates in side impacts and only when t he veh icle
accele ration registe red by the co ntrol u nit is high enoug h. If t his ra te
is below the reference va lue programmed into the control unit, the
side airbags w ill not be triggered, eve n though the car may be badly
damaged as a result of the co llision . It is not possib le to define an
airbag trigger ing range that w ill cover every possible ang le of impact,
sinc e the circumstances will vary co nsiderab ly between one col lision
and another . Important factors incl ude, for example, the nature
(hard or soft) of the impact ing object, the a ngle of impact, vehicle
speed, etc.~
page 165.
Aside from the ir normal safety fu nction, safe ty be lts 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 provide protection.
T he airbag system is not a substitute for your safe ty belt. Rathe r, it is
part of the overall occupant restraint system in your veh icle. Always
remembe r th at the airbag system can on ly help to protect you if yo u
are wear ing your safety belt and wearing it proper ly . This is another
reaso n why yo u sho uld always wea r your sa fety be lts, no t jus t becau se
the law requires you to do so~
page 135, "General notes".
It is impo rtan t to remember that while the side curtain airbag sys tem
is des igned to he lp reduce the like lihood of ser ious injur ies, other
injuries, for example, swe lling, bruising, and minor abrasions can
also be assoc iated with t hese airbags upon deployment . Remembe r
too, these airbags w ill dep loy only once and on ly in certain kinds of
a cci den ts -your safe ty belts a re always there to offer protection .
The side curtain airbag system basically consists of:
• The e lec tron ic cont rol mo dule and e xte rnal si de impact sensors
• The side curtain air bags above the front and rear side windows
~

• The airbag indicator light in the instrument panel
The airbag system is monitored electronically to make certain it is
functioning properly at all times. Each time you turn on the ignition,
the airbag system indicator light will come on for a few seconds (self
diagnostics).
The side curtain airbag is not activated:
• if the ignition is turned off,
• in side collisions when the acceleration measured by the sensor is
too low,
• in rear-end collisions,
• in rollovers.
& WARNING
• Safety belts and the airbag system will only provide protection
when occupants are in the proper seating position =>
page 73,
"General recommendations" .
• If the airbag indicator light comes on when the vehicle is being
used , have the system inspected immediately by your authorized
Audi dealer. The side curtain airbag may not work properly even
when the vehicle acceleration in a side collision is high enough to
activate the airbag. •

Airbag system
How side curtain airbags work
Side curtain airbags can work together with side airbags
to help reduce the risk of head and upper torso injuries for
occupants who are properly restrained.
Fig. 143 Illustration
of principle: Inflated
s ide curtain airbags on
the left side
The side curtain airbags inflate between the occupant and the
w indo ws on the side of the vehicle that is struck in a side collision
=> fig . 143.
When the system is triggered, the side curtain airbag is filled with
propellant gas and breaks through a seam above the front and rear
side windows identif ied by the AIRBAG label. In order to help provide
this additional protection, the side curtain airbag must inflate with in
the blink of an eye at very high speed and with great force. The side
curtain airbag could injure you if your seating position is not proper or
upright or if items are located in the area where the supplemental
side curtain airbag inflates. This applies especially to ch ildren
::::>page 167.
Although they are not a soft pillow, side curtain airbags can "cushion"
the impact and in this way they can help to reduce the risk of injury to
the head and the upper part of the body.
A fine dust may develop when the airbag deploys. This is quite no rmal
and does not mean there is a fire in the vehicle. •

Battery diagnosis
Battery diagnosis continuously determines the state of the battery.
Sensors determine battery voltage, battery current and battery
temperature. This determines the current state of charge and the
power of the battery .
Idling current management
Idling current management reduces energy consumption while the
vehicle is standing. With the ignition switched off, it controls the
energy supply to the various electrical components. Data from
battery diagnosis is considered.
Depending on the battery's state of charge , individual consumers are
gradually turned off to prevent excessive discharge of the battery and
thus maintain starting capability.
Dynamic energy management
While the vehicle is being driven, dynamic energy management
distributes the energy generated according to the needs of the indi­
v idual components. It regulates consumption, so that more electrical
energy is not being used than is being generated and ensures an
optimal state of charge for the battery.
[ i] Tips
• But even energy management cannot negate the limits of physics.
Consider that the power and life of a battery are limited.
• If starting ability is threatened, you are informed by a warning
=> page 196, "Driver notification in the instrument cluster display". •
What you should know
The highest priority is given to maintaining starting capa­
bility.
The battery is severely taxed in short-distance driving, in city traffic
and during the cold time of year. Abundant electrical energy is
Controls and equip­
ment Safety first Vehicle operation
required, but only a little is generated. It is also critical if the engine
is
not running and electrical components are turned on. In this
instance energy is being consumed but none is being generated .
It is in precisely these situations that you will notice energy manage­
ment actively regulating the distribution of energy.
Vehicle stands for an extended period
If you do not drive your vehicle over a period of several days or weeks,
electrical components are gradually cut back or switched off. This
reduces energy consumption and maintains starting capability over a
longer period.
Take into consideration that when you unlock your vehicle, some
convenience functions, such as the remote key or power seat adjust ­
ment, may not be available. The convenience functions will be avail­
able again when you turn on the ignition and start the engine .
With the engine turned off
If you listen to the radio, for example, with the engine turned off, the
battery is being discharged.
If starting capability is jeopardized due to energy consumption, a
message appears in the driver information display.
You have to start the engine to charge the battery.
With the engine running
Although electrical energy is generated when the vehicle is being
driven, the battery can become discharged. This happens mostly
when little energy is being generated and a great deal consumed and
the battery's state of charge is not optimal.
To bring the energy balance back into equilibrium, consumers which
require especially large amounts of energy are temporarily cut back
or switched off. Heating systems in particular require a great deal of
energy . If you notice, for example , that the heated seats* or the
heated rear window are not heating, they have been temporarily cut
back or switched off. These systems will be available again as soon as
the energy balance has been restored. .,

High temperatures, as from exposure to intense sunlight, intensify
the corrosive effect particularly when humidity is high as well.
Under certa in circumstances,
weekly washing may be necessary .
Under other conditions, a month ly washing and waxing may be
adequate.
After the winter, the underside of the vehicle should be thoroughly
washed, preferably in a profess ional car wash.
& WARNING
Always read and heed all WARNINGS and other information
=> page 206.
0 Note
You should remove debris (such as insects) from the headlight lenses
on a regular basis, for example when refueling yo ur vehicle. Never
clean the headlights with a dry cloth or sponge. Use a wet cloth or
sponge. It is best to use soapy wate r.•
Automatic car wash
The vehicle can be washed in almost any modern auto­
matic car wash.
The vehicle paint is so durable that the vehicle can normally be
washed without problems in an automatic car wash. However, the
effect on the paint depends to a large extent o n the design of the
facility, the filtering of the wash water, the type of wash and care
material, e tc. If the paint has a dull appearance after going through
the car wash or is scratched, bring this to the attention of the oper­
ator immediately .
If necessary, use a different car wash.
Before going through a car wash, be sure to take the usual precau­
tions such as closing the windows and panoramic sliding sunroof*.
Remove ante nna if applicable.
Safety first
If you have installed additional accessories on the vehicle - such as
spoilers, roof rack, etc. - it is best to ask the car wash operator if these
should be removed.
& WARNING
Always read and heed all WARNINGS and other information
=>page 206. •
Washing the vehicle by hand
A lot of water is needed when washing a vehicle by hand.
-Before you start wash ing, ma ke sure you have read and
understood the WARNINGS ~
& in "General informa­
tion" on
page 206.
-First soak all dried dirt until it is soft, then rinse it off.
- As you clean your vehicle, start with the roof and work your
way down to the bottom, using a sponge, a sponge glove
or a clean brush.
- Rinse the sponge or the sponge glove often, flushing it
clean each time.
- Use special car shampoo only for very persistent dirt.
- Rinse the car thoroughly with water .
- Use a chamois leather to gently wipe the exter ior dry .
Use a separate sponge for cleaning the whee ls, door s ills and other
regions exposed to road dirt. In this way, you will not scratch the
paint with coarse particles imbedded in the sponge the next time you
wash the car . .,,

Windows
Clear vision to all sides.
Clean all windows regularly to remove road film and carwash
wax buildup.
- Remove snow from windows using a brush.
- Use a plastic ice scraper to remove ice from windows and
mirrors.
- Remove other residue on the w indows with a spray-on
glass cleaner .
- Wipe the windows dry with a clean piece of cloth or
kitchen paper towel.
T he best way to remove snow from w indows and mirrors is to use a
brush. Use a non-abrasive plastic ice s craper - be tter st ill, a spray
deicer -to remove ice from windows and mirrors.
Th e w indows must not be cleaned with insect remover or wax since
these can interfere with the function of the w indshield wiper blades
(chatte r) .
Oil, grease or s ilicone residue can be removed with glass cleane r or
s ili cone remover. Howeve r, wax residue requires the use of a specially
formulated solvent . Please contact your author ized Aud i dealer for
advice on safe products for wax remova l.
W indows shou ld also be cleaned on the inside at regu lar i nte rvals.
