128 Airbag system
-in front -end collisions
- in rear-end co llisions
- in ro llovers.
In some types of accidents the front airbags
and side a irbags may be triggered together .
A WARNING
-Safety belts and the a irbag system wi ll
only p rov ide protection when occupants
are in the proper sea ting posit ion
¢page 128.
- If the airbag indicato r light comes on
when the vehicle is being used, have the
system inspected immediately by your
authorized Audi dealer. The airbag may
not work properly when the vehicle ac
celeration in a side co llision is high
enough to activate the airbag.
How supplemental side airbags work
-
Side airbags deploy instantly and can help re
duce the risk of upper torso injuries for occu
pants who are properly restrained.
Fig. 127 Inflated side air bags on left side of vehicle
When the system is triggered , the airbag is
fi lled with propellant gas and breaks through
a seam in the seat surface area marked "AIR
B AG".
It expands between the side t rim panel
and the passenger. In order to help provide
this additiona l protection, the side airbag
must inflate with in a fraction of a second at
very high speed and with great force. The sup
plemental side airbag could injure you if your
seating position is not proper or upright or if
items are located in the area where the sup
p lemental side a irbag expands . This appl ies
especia lly to childre n ¢ page 130, Child Safe- ty
. Supplemental side airbags inflate between
the occupant and the door panel on the side
of the vehicle that is struck in certain side col
li sion
¢ fig. 12 7.
Although they are not a soft pillow, they can
"cushion" the impact and in this way they can
help to reduce the risk of injury to the upper
part of the body.
A fine dust may deve lop when the airbag de
ploys . This is normal and does not mean there
is a fire in the vehicle.
Important safety instructions on the
side airbag system
Airbags are only supplemental restraints. Al
ways properly wear safety belts and ride in a
proper seating position .
There is a lot that you and your passengers
must know and act accord ingly to help the
safety belts and airbags do their job to pro
vide supplemental protection .
A WARNING
-
An inflat ing s ide a irbag can cause se rious
or fata l injury. Improperly wearing safety
bel ts and imp roper sea ting positions in
crease the r isk of se rious personal injury
and dea th whenever a vehicle is being
used .
- In order to reduce the risk of in jury w hen
the supplemental side airbag inflates:
- Always sit in an upright position and
never lean aga inst the area whe re the
supplementa l side airbag is located .
- Never let a child or anyone e lse rest
their head aga inst the s ide trim pane l
i n the area where the s upplementa l
s ide airbag inflates .
- Always make sure that safety be lts are
worn correctly,
- Do not let anyone s itting in the front
seat put their hand or any other parts
of the ir body out of the window.
- Always make sure that the s ide airbag
can inf late without inte rfe rence.
-Blend must contain not more than 15%
MTBE.
Seasonally adjusted gasoline
Many gasoline grades are blended to perform
espec ially we ll for winter or summer driving.
During seasonal change-over, we suggest that
you fill up at busy gas stat ions where the sea
sonal adjustment is more likely to be made in
time .
(D Note
-Methanol fuels which do not meet these
requirements may cause corrosion and
damage to plastic and rubber compo
nents in the fuel system .
- Do not use fue ls that fail to meet the
specified criter ia in this chapter.
- If you are unable to determine whether
or not a particular fue l blend meets the
specifications, ask your service station or
its fuel supp lier.
- Do not use fuel for which the contents
cannot be identified.
- Fuel system damage and performance
problems resulting from the use of fuels
different from those specified are not
the responsibility of Audi and are not
covered under the New Vehicle or the Emission Control System Warranties.
- If you experience a loss of fuel economy
or driveability and performance prob l ems due to the use of one of these fuel
blends, we recommend that you switch
to unblended fuel.
Gasoline additives
A major concern among many auto manufac
turers is carbon deposit build- up caused by
the type of gasoline you use.
Although gasoline grades differ from one manufacturer to another , they have certain
things in common. All gasoline grades contain
substances that can cause deposits to collect
on vital engine parts, such as fuel injectors
and intake valves. Although most gasoline brands include additives to keep engine and

A udi recommends using TOP TIER Detergent
Gasoline. For more info rmation on TOP TIER
Detergent Gasoline, please go to the official
website (www.toptiergas.com).
After an extended period of using inadeq uate
fuels, built-up carbon deposits can rob yo ur
engine of peak performance.

Fuel tank
Fuel filler neck
The fuel filler neck is located on the right rear
side panel behind the fuel fille r flap.
If the unlocking system should fail, you can
still open the flap manually -for detailed in
structions see
¢ page 167.
You can find the fuel tank capacity of your ve hicle in
Technical Data ¢ page 217.
The label on the inside of the fuel fi ller flap
tells you the correct fue l for your vehicle. For
more information about fuel specifications,
see
¢ page 164.
Your vehicle fue l tank has an on -board refue l
ing vapor recovery system. This feature helps
to prevent fuel vapors from escaping from the
tank and polluting the environment while you refuel your vehicle . In order to fill the tank
properly while protecting the environment,
please fo llow this refueling procedure careful
ly.
_&. WARNING
Under normal operating conditions, never
carry additional fuel containers in your car.

When charging at low voltages (e.g . with a
trickle charger ), the battery cables do not
have to be disconnected first. Before charging
at
high voltages, i.e. "fast charging", you
must disconnect both cables. In either case,
follow the instructions from the manufacturer
of the charger .
Fastcharging a battery is
dangerous ¢ & in
Working on the battery on page 179 .
It re
quires special charging equipment and the knowledge to go with it. We recommend hav
ing your battery fast charged only by a quali
fied workshop.
A discharged battery can
freeze at tempera
tures of only 32 °F (0 °C) . Allow a frozen bat
tery to thaw completely before attempting to
charge it¢ & . However, we recommend not
using a thawed battery again because the bat
tery casing can be cracked due to ice forma
tion and can leak battery acid .
Do not open the battery caps when charging
the battery.
_& WARNING
-
Charging a battery can be dangerous.
- Never charge a frozen battery .
It may ex
plode because of gas trapped in the ice.
Allow a frozen battery to thaw out first.
- Do not reuse batteries which 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
trical spark. Do not smoke. Hydrogen gas
generated by the battery is explosive.
- To reduce the danger of explosion , never
connect or disconnect charger cables
while the charger is operating.
- Fast charging a battery is dangerous and
should only be attempted by a compe
tent technician with the proper equip ment.
Checking and filling 181
- Battery acid that may spill during charg
ing should be washed off with a solution
of warm water and baking soda to neu
tralize the acid .
@ Note
Never use a fast charger as a booster to
start the engine. This will seriously dam
age sensitive electronic components, such
as control units, relays, radio, etc ., as well
as the battery charger .
(D Tips
-The vehicle battery must not be charged
with a standard small charger that plugs
into the cigarette lighter or outlet .
- Only charge the battery through the con
nections in the luggage compartment.
Replacing the battery
The new battery mus t have the same specifi
cations as the old one.
Your vehicle is equipped with an intelligent
energy management system for distributing
electricity¢
page 147 . The battery charges
better in vehicles with the energy manage
ment system than in vehicles without the sys
tem . To ensure that the additional power is
available after replacing the battery , replacing
with the same type of battery from the same manufacturer (like the battery that was deliv
ered with the vehicle) is recommended. An au
thorized dealer must code the battery in the
energy management control module.
The new battery must have the same capacity,
voltage (12 volts), current and design and it
must be sealed with plugs. The battery must
conform to the standards TL 825 06 (from
April 2008) and VW 7 SO 73 (from April 2010).
Since the vehicle battery is difficu lt to reach,
we recommend having the battery replaced by
an authori zed Audi RB dealer or other quali-
fied workshop . ..,. •

- Your vehicle is equipped with a specia l
battery. Installing a different type of
battery can cause prob lems in the vehi
cle electrical system. When replacing the
vehicle battery, always install one with
the same spec ificat ions as the original
battery .
- Make sure that the gas venting hose is
always connected to the o riginal open ing
on the battery side. Otherw ise gasses or
ba tte ry acid could leak out .
- Battery holder and term inals a lways
have to be secured cor rectly.
- Read and follow the warnings under
9 page 179, Working on the battery be
fore performing any work on the batte ry.
@) For the sake of the environment
Because of the problem of proper disposal
of a battery, we recommend your author
ized Audi dealer change the battery for
you . Batteries contain sulfur ic ac id and
lead and must always be disposed of prop
erly in compliance with a ll environmenta l
reg ulations. D isposing of vehicle batteries
improperly is very dangerous to the envi
ronment. Make sure that the removed bat
tery ca nnot overbalance, otherwise sulfu
r ic acid might escape!

Tires and wheels
Tires
General notes
Tires may be the least appreciated and most
abused parts of a motor vehicle .
Tires may be the least appreciated and most
abused parts of a motor vehicle . T ires are,
however, one of the most important parts of a
vehicle, particularly considering the compara
tively small patch of rubber on eac h tire that
assures that a ll- important contact between
you, you r vehicle and the road.
Maintaining the correct tire pressure, mak ing
sure that your vehicle and its tires do not have
to carry mo re weight than they can safely han
d le, avoiding damage from road hazards and
r eg ularly inspec ting t ires for damage i nclud
ing cuts, slashes irregu la r wear and ove rall
condition are the most important things that
you can do to he lp avoid sudden tire failure in
cluding tread separat ion and blowouts.
Avoiding damage If you have to d rive over a curb or similar ob
stacle, drive very slow ly and as close as possi
b le at a right angle to the curb.
A lways keep chemicals includ ing grease, o il ,
gasoline and brake fluid off the t ires .
I nspect the t ires regularly for damage (cuts,
cracks or b listers, etc.). Remove any fo reign
bod ies embedde d in the treads.
Storing tires Mark tires when you remove them to indicate
the direction of rotation . T his ensures you to
be ab le to mount them correctly when you re
i nstall them .
When removed, the whee ls or t ires should be
sto red in a cool, d ry and preferably dark place .
Store tires in a vertical pos ition if they are not
mounted on rims, in a horizontal pos it ion if
they are mounted on rims .
