The side airbag system supplements the safety be lts and can help to reduce the risk of injury to
the dr iver's and front passenger's upper torso on
the side of the vehicle that is struck in a side col­
lision . The airbag deploys on ly in side impacts
and only when the vehicle acceleration reg istered
by the control unit is h igh enough. If this rate is
be low the reference va lue programmed into the
control unit, the s ide airbags will not be tr ig­
gered, even though the car may be badly dam ­
aged as a result of the collision.
It i s not possib le
to define an airbag triggering range that wi ll cov­
er every possible angle of impact, since the cir ­
cumstances will vary considerably between one
coll is ion and another. Important factors include,
for example , the nature (hard or soft) of the im­
pacting object, the ang le of impact, vehicle
speed , etc .
r::;;, page 154, Important safety in­
structions on the side airbag system .
Aside from their normal safety function, safety
be lts work to he lp keep the driver or front pas­
senger in pos it ion in the event of a side collision
so that the s ide a irbags can provide p rotection.
The airbag system is
not a substitute for your
safety belt . Rather, it is part of the overall occu­
pant restraint system i n your veh icle . Always re­
member that the s ide airbag system can only
he lp to p rotect yo u if you a re wea ring your safety
be lt and wea ring it properly. This is another rea­
son why you shou ld always wear your safety
be lts, not just because the law requi res you to do
so
r::;;, page 130, General information.
It is important to remember that while the s up­
p lemental side ai rbag system is designed to re­
duce the like lihood of serious injur ies, other inju­
ries, for example, swelling, bruising, and minor
abrasions can a lso be associated with deployed
side airbags. Remember too , side airbags will de­
ploy only once and only in certain kinds of acci­
dents -your safety belts are always t here to offer
p rotection.
Vehicle damage, repair costs or even the lack of
vehicle damage are not necessarily an indication
of over-sensitive o r failed airbag activation . In
some coll is io ns, both front and s ide a irbags may
in flate. Remember too, that airbags will deploy
only once and only in ce rtain k inds of coll is ions -
Airb ag sys tem
your safety belts are always there to offer protec­
tion in those accidents in which airbags are not
s u pposed to deploy or when they have already
deployed .
The side airbag system w ill n ot deploy:
- when t he ignit io n i s t urned off
- in side co llisions whe n the acceleration meas-
ured by the sensor is too low
- in front-end coll is io ns
- in rear-end col lisions
- in rollovers .
In some types of accidents the front airbags, side
curtain airbags and side airbags may be triggered
together .
A WARNING
--Safety belts and the airbag system will only
p rov ide protect ion when occupants are in
the prope r seat ing pos ition
r::;;, page 154 .
- If the ai rbag ind icator light r::;;, page 19
comes when the veh icle is being used, have
the system inspected immedia tely by your
a uthor ized Audi dealer.
It is possib le th at
the airbag will inflate when i t is not sup­
posed to, or w ill not inf late w hen it should.
How supplemental side airbags work
Side airbags deploy ins tantly and can help re­
duce the risk of upper torso injuries for occu­
pants who ore properly restrained.

Fuel and Refueling
Gasoline additives
A major concern among many auto manufactur­
ers is carbon deposit build-up ca used by the type
of gasoline you use.
Although gasoline grades d iffer from one manu­
facturer to another, they have certain things in
common. All gasoline grades contain substances
that can cause deposits to collect on v ital engine
parts, such as fuel injectors and intake valves. Al­
though most gasoline brands include additives to
keep engine and fuel systems clean, they are not
equally effective.
Audi recommends using TOP TIER Detergent Gas­
oline. For more information on TOP TIER Deter­
gent Gasoline, please go to the official website (www.toptiergas.com).
After an extended period of using inadequate
fue ls, built-up carbon depos its can rob your en­
g ine of peak performance.
CD Note
- Damage or malfunction due to poor fuel
quality is not covered by the Audi New Vehi­
cle Limited Warranty .
- Do not add aftermarket fuel additive prod­
ucts to yo ur fuel tank.
Refueling
Fuel filler neck
The fuel filler neck is located on the right rear
side panel behind the fuel f iller flap .
If the power locking system should fail, you can
still open the flap manually -for detailed instruc­
tions see
c> page 202.
You can find the fuel tank capacity of your vehicle
in
c> page 256 .
The label on the inside of the fuel filler flap tells
you the correct fue l for your vehicle. For more in­
formation about fuel specifications, see
<=>page 198.
Your vehicle fuel tank has an on-board refuelling
vapor recovery system. This feature he lps to pre­
vent fuel vapors from escaping from the tank and
200
polluting the environment whi le you refuel your
vehicle. In order to fill the tank proper ly while
protecting the env ironment, please follow th is
refueling procedure carefully.
A WARNING
Under normal operating conditions, never car­
ry additional fuel containers in your car. Gas
can isters and other containers used to trans­
port fue l can be dangerous. Such containers,
full or empty, may leak and could cause a fire
in a col lision.
If you must transport fuel to
use for your lawn mower, snow blower, etc.,
be very careful and always observe local and
state laws regarding the use, transportation
and storage of such fuel containers. Make cer­
tain the container meets industry standards (ANSI/ASTM F852 -86).
CD Note
Never drive your vehicle until the fuel tank is
complete ly empty. The irregular supply of
fuel can cause misfiring. Gasoline could enter the exhaust system and damage the catalytic
converte r.

A discharged battery can freez e at temperatures
of only 32 °F (0 °C) . Allow a frozen battery to
thaw completely before attempt ing to charge it
~ _& . However, we recommend not us ing a
thawed batte ry again because the battery casing
can be cracked due to ice format ion and can leak
battery acid.
Battery charg ing (Maximum charging rate of
30 amps /14.8 Volt )
When cha rging at low vo ltages (e .g . with a tric k­
l e char ger ),
the battery cables do not have to be
disconnected first. The battery caps should
not
be opened when charging a battery.
It is not necessary to remove the batte ry from
the luggage compartme nt.
F a st cha rging the battery (charg ing rate
above 14.8 Volt s)
For techn ical reasons do not use a battery charg­
e r that uses voltage greate r 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 manufactur­
er when charging your battery .
Check ing and Filling
-Never charge a frozen battery . It may ex­
plode because of gas trapped in the ice. Al­
low a frozen battery to thaw out first.
- Do not reuse batteries which were frozen.
The battery hous ing may have cracked and
weakened when the battery froze.
- Charge the battery in a well ventilated area. Keep away from open flame or electrical
spark. Do not smoke . Hydrogen gas generat­
ed by the battery is explos ive.
- To reduce the danger of explosion, never
connect or disconnect charger cables while
the charger is operating .
- Fast charg ing a battery is dangerous and
should only be attempted by a competent
technician w ith the proper equipment.
- Battery acid that may spill during charging should be washed off w ith a solution of
warm water and baking soda to neutralize
the acid .
@ Note
Never use a fast charger as a booster to start
the engine . This will seriously damage sensi­
tive electronic components, such as control units, re lays, radio, etc., as well as the battery
cha rge r.
Battery replacement
The new battery must have the same specifica­
tions and dimensions as the original equipment
battery.
Intelligent energy management in your vehicle is
r esponsib le for distr ibut ing the e lectrical energy
t hr oughou t your vehicle ~
page 182. The intelli­
gent energy management system will keep the
engine battery charged better then vehicles with ­
out this system. To make sure the additional
electrical energy is available once again after you
have changed the battery, we recommend that
you install batteries of the same type and manu­
facture only (the same as those installed at the
t ime your vehicle was delivered) . Specifications
are listed on the battery housing . Your author­
ized Audi dealer must code the battery in the en-
ergy managemen t system to enable you to use
