.. Bring the steering wheel into the desired
position .
.. Push the lever against the steering column
until it latches .
_& WARNING
Improper use of steering wheel adjust­
ment and improper seating position can
cause serious personal injury.
- Adjust the steering wheel column only
when the veh icle is not moving to pre­
vent loss of vehicle control.
- Adjust the driver's seat or steering wheel
so that there is a min imum of 10 inches
(25 cm) between your chest and the
steering wheel¢
page 122, fig. 109 . If
you cannot maintain this minimum dis­
tance, the airbag system cannot protect
you properly.
- If phys ica l limitations prevent you from
sitting 10 inches (25 cm) or more from
the steering wheel, check w ith your au­
thorized Aud i dealer to see if adaptive
equipment is availab le .
- If the steering wheel is alig ned with your
face, the supplemental driver's airbag cannot p rovid e as much protectio n in an
accident. Always make sure that the steer
ing whee l is aligned with your
chest.
- Always hold the steering wheel with your
hands at the 9 o'clock and 3 o'clock posi­
tions to reduce the risk of personal injury
if the driver's airbag deploys.
- Never hold the steering wheel at the 12
o'clock position or with your hands inside
the steering wheel rim or on the steering
wheel hub. Holding the steering wheel
the wrong way can cause serious injuries
to the hands, arms and head if the driv­
er's airbag deploys.

driver's seat, see
Q page 54 .
.&, WARNING
Drivers who are unbelted, out of position
or too close to the airbag can be seriously
injured by an airbag as it unfolds. To help
reduce the risk of serious personal injury:
- Always adjust the driver's seat and the
steering wheel so that there are at least
10 inches (25 cm) between your breast­
bone and the steering wheel.
- Always adjust the driver's seat and the
steering wheel so that there are at least
4 inches (10 cm) between the knees and
the lower part of the instrument panel.
- Always hold the steering wheel on the
outside of the steering wheel rim with
your hands at the 9 o'clock and 3 o'clock positions to help reduce the risk of per­
sonal injury if the driver's airbag inflates.
- Never hold the steering wheel at the
12 o'clock position or with your hands at
other positions inside the steering wheel
rim or on the steering wheel hub. Hold­
ing the steering wheel the wrong way
can cause serious injuries to the hands,
arms and head if the driver's airbag in­
flates.
- Pointing the steering wheel toward your
face decreases the ability of the supple­
mental driver's airbag to protect you in a
collision.
- Always sit in an upright position and nev­
er lean against or place any part of your
body too close to the area where the air­
bags are located.
-
Driving safety 123
-Before driving, always adjust the front
seats properly and make sure that all passengers are properly restrained.
- For adjustable head restraints: before
driving, always also adjust the head re­
straints properly.
- Never adjust the seats while the vehicle is moving. Your seat may move unexpect­
edly and you could lose control of the ve­ hicle.
- Never drive with the backrest reclined or
tilted far back! The farther the backrests are tilted back, the greater the risk of in­
jury due to incorrect positioning of the safety belt and improper seating posi­
tion.
- Children must always ride in child seats
Q page 166. Special precautions apply
when installing a child seat on the front
passenger seat ¢
page 140.
Proper seating position for the front
passenger
The proper front passenger seating position
is important for safe, relaxed driving.
For your own safety and to reduce the risk of
injury in the event of an accident, we recom­
mend that you adjust the seat for the front
passenger to the following position:
.. Adjust the angle of the seatback so that it is
in an upright position and your back comes
in full contact with it whenever the vehicle is
moving.
.. For adjustable head restraints: adjust the
head restraint so the upper edge is as even
as possible with the top of your head. If that
is not possible, try to adjust the head re­
straint so that it is as close to this position
as possible
¢ page 125. Move the head re­
straint so that it is as close to the back of
the head as possible .
.. Keep both feet flat on the floor in front of
the front passenger seat.
.. Fasten and wear safety belts correctly

detailed information about airbags, safety
belts and child safety in this and the other
chapters that make up the owner's literature.
Please be sure to heed the WARNINGS -they
are ex tremely important for your safety and
the safety of your passengers, especially in ­
fants and small children .
A WARNING
Never rely on airbags alone for protection.
- Even when they deploy, airbags provide only supplemental protection .
- Airbag work most effectively when used
with properly worn safety belts .
- Therefore, always wear your safety belts
and make sure that everybody in your ve ­
hicle is properly restrained .
- Always hold the steering wheel with both
hands on the outside of the steering
wheel rim at the 9:00 o'clock and 3:00
o'clock positions to help reduce the risk
of personal injury if the driver's airbag in­
flates.
- Never hold the steering wheel at the 12
o'clock position or with your hands any­
where inside the steering wheel or on the
steering wheel hub. Holding the steering
wheel the wrong way increases the risk of severe injury to the arms, hands, and
head if the driver airbag deploys .
A WARNING
Objects between you and the airbag will
increase the risk of injury in a crash by in­
terfering with the way the airbag unfolds
and/or by being pushed into you as the air­
bag inflates.
- Always make sure nothing is in the front
airbag deployment zone that could be
struck by the airbag when it inflates.
- Objects in the zone of a deploying airbag
can become projectiles when the airbag
deploys and cause serious personal in­
jury.
- Never hold things in your hands or on
your lap when the vehicle is in use .
-
Airbag system 145
-Never place accessories or other objects
(such as cup holders, telephone brackets,
note pads, navigation systems, or things
that are large, heavy, or bulky) on the
doors; never attach then to the doors or
the windshield; never place them over or
near or attach them to the area marked
,,AIRBAG " on the steering wheel, instru­
ment panel or the seat backrests; never
place them between these areas and you
or any other person in the vehicle.
- Never attach objects to the windshield
above the passenger front airbag, such
as accessory GPS navigation units or mu­
sic players. Such objects could cause seri­
ous injury in a collision, especially when
the airbags inflate.
- Never recline the front passenger seat to transport objects. Items can also move
into the deployment area of the side air ­
bags or the front airbag during breaking
or in a sudden maneuver . Objects near
the airbags can fly dangerously through
the passenger compartment and cause
injury, particularly when the seat is re­
clined and the airbags inflate.
A WARNING
-=
A person on the front passenger seat , es-
pecially infants and small children, will re­
ceive serious injuries and can even be kil­
led by being too close to the airbag when
it inflates.
- Although the Advanced Airbag System in your vehicle is designed to turn
off the
front passenger airbag if an infant or a
small child is on the front passenger
seat, nobody can absolutely guarantee
that deployment under these special conditions is impossible in all conceiva­
ble situations that may happen during
the useful life of your vehicle.
- The Advanced Airbag System can deploy
in accordance with the ,,low risk" option

ways observe local and state laws regard­
ing the use, transportation and storage of
such fuel containers . Make certain the con­
tainer meets industry standards (ANSI/
ASTM F852 -86) .
(D Note
Never drive your vehicle until the fuel tank
is completely empty . The irregular supply
of fuel can cause misfiring. Gasoline could
enter the exhaust system and damage the
catalytic converter.
Fueling procedure
Fig. 144 Rig ht rear side of the vehicle: opening the
fue l filler door
Fig. 145 Fu el filler door w ith atta ched fuel cap
The fuel filler door is unlocked or locked by
the central locking system.
Opening the fuel filler door
.,. Press the left side of the fuel filler door to
open it -arrow-
c::> fig . 144 .
• Unscrew the tank cap counterclockwise.
• Place the cap from above on the open fuel
filler door
c::> fig . 145. Closing the fuel cap
.,.
Turn the fuel cap clockwise until you hear it
lock.
.,. Close fuel filler door until it latches.
Once the pump nozzle switches off , the fuel
tank is "full". Do not fill the tank more. Other­
wise the expansion space in the tank will be
filled.
The correct fuel type for your vehicle can be
found on a label located on the inside of the
fuel filler door. Additional information on fuel
c::>page206.
The fuel tank capacity of your vehicle is in the
Technical Data c::> page 266.
To avoid fuel spilling or evaporating from the
fuel tank always close fuel filler cap properly
and completely. An improperly closed fuel fill­
er cap may also cause the MIL lamp
c::> page 29
to come on.
A WARNING
Improper refueling or handling of fuel can
cause fire, explosion and severe burns.
- Fuel is highly flammable and can cause
severe burns and other injuries.
- Failure to shut the engine off while refu­
eling and/or to insert the pump nozzle
fully into the fuel filler neck could cause
fuel to spray out of filler neck or to
over­
flow. Fuel spray and overflowing fuel can
cause a fire .
- Never use a cellular telephone while re­
fueling. The electromagnetic radiation can cause sparks that can ignite fuel va­
pors and cause a fire .
- Never get back into your vehicle while re­
fueling . If in exceptional circumstances
you must get back in your vehicle while
refueling, make certain that you close
the door and touch metal to discharge
static electricity before touching the fill­
er nozzle again. Static electricity can
cause sparks that can ignite fuel vapors released during refueling .

The cooling system has been filled at the fac­
tory with a permanent coolant which does not need to be changed. The coolant consists of a
mixture of spec ia lly conditioned water and the
manufacturer's glycol-based coolant addi-
tive Gl3 antifreeze with anticorros ion addi ­
tives (50% fo r USA models; 60% for Canadian
models) . This mixture both assures th e neces­
sary frost protect ion a nd p rotects me tal com ­
ponents in the engine 's coo ling system from
corrosion and scaling.
It al so raises the boil­
ing po int o f the coo lant .
D o no t reduce the concentration of t he coo l­
an t in the summer by ad ding plain w ate r.
The
proportion of coolant additive must be at
lea st 50 % but not more than 60%
to main­
tain ant ifreeze protection and cooling efficien­
cy. If the coolant frost protect ion is too low ,
the coolant cou ld free ze and damage the veh i­
cle heating and eng ine cooling system.
F or yea r-round driv ing, antifreeze is added at
the facto ry for temperatures down to:
- -3 1 °F ( -3 5°C) USA
- -4 0°F ( -4 0°C) Canada.
If you must add coolant, use a m ixture of wa ­
ter and coolant addit ive. M ixing the coolant

• Add coolant mixed in the correct ratio
¢page 216 up to the upper marking.
• Make sure that the fluid level rema ins sta-
ble. Add more coolant if necessary.
• Clove the cap securely.
A coo lant loss suggests a leak. Immediately
drive your vehicle to an authorized repair fa­
cility and have the coolant system inspected.
If the coolant system is not leaking, a loss can
come from the coolant cooking through over­
heat ing and being pushed out of the coolant
system.
.8, WARNING
The cool ing system is under pressure and
can get very hot. Reduce the risk of scald­
ing from hot coolant by following these
steps .
- Do not open the coo lant expansion tank
cap with the engine hot . There is a risk of
burns.
- T urn off the engine and allow it to cool
down .
- Protect your face, hands and arms from
escaping fluid and steam by covering the
cap with a large, thick rag.
- T urn the cap slowly and ve ry carefu lly in
a counter-clockwise direction wh ile ap­
plying light, downward pressure on the
top of the cap.
- To avoid being b urned, do not spill anti­
freeze or coo lant on the exhaust system
or hot eng ine parts. Under certain condi­
t ions, the ethylene g lycol in engine cool­
ant can catch fire.
- The coo lant add itive and the coolant can
be dange rous to your hea lth. For th is
reason, keep the coolant in the or ig inal
conta iner away from children. There is a
risk of poisoning.
- Whe n work ing in the engine compart­
ment, remembe r that the radiator fan
can swit ch on even if the ignition is
switched off, wh ic h increases the risk of
persona l inju ry .
(D Note
Do not add coo lant if the expansion tank is
empty. Air cou ld enter the cooling system
and damage the engine. If this is the case,
do not continue dr iving. See your author­
i zed Audi dealer or qualified repair fac ility .
Radiator fan
The radiator fan switches on automatically by
itself
An a uxiliary electric radiator fan switches on
and off depending on coolant temperature
and other vehicle operat ing condit ions.
After you switch the engine off, the auxi liary
fan can continue running for up to 10 m inutes
- even w ith the ignition off.
It can even switch
on again later by itself¢.&. , if
- the temperature of the engine coo lant rises
due to the heat build- up from the engine in
the engine compartment, or
- the engine compartment heats up because
the vehicle is parked in intense sunlight.
.8, WARNING ,-
- To reduce the risk of personal injury nev-
er touch the radiator fan.
- The a uxiliary electric fan is temperat ure
controlled and can sw itch on suddenly
even when the engine is not ru nning.
- The auxiliary radiator fan sw itches on a u­
tomatically when the engine coo lant
reaches a certain temperature and will
continue to run until the coolant temper­
ature drops.

220 Checking and Filling
Battery
General information
Under normal operating conditions, the bat­
tery in your Audi does not need any mainte­
nance. With
high outs ide temperatu res or
long daily drives we recommend that you have
the electro lyte level checked by a service fa­
cility. The e lectrolyte level shou ld also be
checked each time the battery is charged
c:>page222.
Have the battery checked when you take your
vehicle in for service. You are well advised to replace a battery that is older than 5 years.
With certain types o f airbag deployment, the
battery is disconnected from the vehicle elec ­
trica l system for safety reasons
c;, .&. in Re­
pair , care and disposal of the airbags on
page 156.
Disconnecting the battery terminals
Some vehicle functions such as power win­
dows are unavai lable if the battery termina ls
are d isconnected. These functions have to be
relearned after the battery terminals are con­
nected again. To prevent this, the battery
should only be disconnected from the vehicle
electrical system when absolutely necessary
for repairs .
To reprogram the functions, proceed as fol­ lows:
Function Reprogramming
Power window one-c;, page 40, Correcting
touch up/down power window mal-
function functions
Remote control key If the vehicle does not
or react to the key, it
convenience key must be synchroni zed
c:>page 33
Digital clock c:>page 10
ESC indicator light The indicator light
goes out after driving
a few meters
Vehicles not driven for long periods
If you do not drive your vehicle over a period
of severa l days or weeks, e lectrica l compo­
nents are gradually sca led back or switched
off. This reduces energy consumption and
maintains starting capability over a longer pe­
riod
c;, page 190. Some of the conven ience
functions may not operate, such as the interi­
or lights or power seat adjustment. The con ­
venience functions will be availab le aga in
when you switch on the ignition and start the
engine.
Winter operation
During the winter months, battery capacity
tends to decrease as temperatures drop. This
is because more power is also consumed wh ile
sta rting, and the headlights, rear window de­
fogger, etc. , are used more often.
Avoid unnecessary power consumpt ion, par­
ticularly in city traffic or when traveling only
short distances. Let your authorized Aud i
dealer check the capacity of the vehicle bat­
tery before winter sets in ~ page 222. A well
charged battery will not on ly prevent starting
problems when the weather is cold, but will
also last longer.
A WARNING -
-Work on the battery requ ires expert
know ledge. Contact your authorized Audi
dealer qualified repair facility for infor­
mat ion regarding the vehicle battery.
There is a risk for chemical burns or ex­
p losions.
- Never open the vehicle batte ry . Do not
try to change the battery electrolyte lev­
el. Otherwise explosive gas will escape
from the battery and increase the risk of
an explosion .
(i) Tips
If your vehicle is left standing for several
weeks at extremely low temperatures, the
vehicle battery should be removed and
stored where it w ill not freeze. This will ..,.

location of the label
c::> page 229, fig . 156.
Most ti res lose a ir naturally over time. They
can also lose some a ir if you drive ove r a pot­
ho le or hit a curb while parking . It is usua lly
not possible to see whether the radial tires
used today are under inflated just by looking
at them.
Therefore, be sure to check tire pressures at
l east once a month and always before going
on a long tr ip. Make sure to take the number
of people and the amount of luggage into ac ­
count when adjusting tire pressure for a trip -
even one that you would not consider to be
" long." See
c::> page 233 , Tires and vehicle
load limits
for more important information .
Always use an accurate tire pressure gauge
when checking and adjusting inflation pres­
sures . Check all of the t ires and be sure not to
forget the spare t ire . If the pressure in any tire
is too high when the tire is "cold ," le t air out
of the tire slowly with the edge of the tire
gauge and keep checking the pressure until
you reach the pressure that is correct for the l oad (passengers and luggage) and kind of
driving you plan to do .
I f the pressure in any tire is too low, note the
diffe rence between the pressure in the cold
tire and the pressure you need and add the air
that you need to reach the cor rect pressure for
the vehicle load (passengers and luggage) for
the tires on your veh icle as lis ted on the on
your veh icle and in this manual and the k ind
of dr iv ing you pla n to do .
Never e xceed th e ma ximum inflatio n pres ­
sure li sted on th e tire s id ewall for an y rea ­
son .
Remember that the vehicle manufacturer, not
the tire manufacturer, determ ines the correct
tire pressure for the t ires on your vehicle .
It is important to check the tire pressure when
the tires are cold .
- Read the req uired ti re pressure from the tire
pressure label. The tire pressure labe l is lo ­
cated on the driver's side B-pi llar . - Tu
rn the va lve stem cap counter -clockwise
to remove it from the tire va lve .
- Place the air pressure gauge on the va lve.
- The tire pressu res should only be checked
and adj usted when the tires are co ld. The
slightly raised pressures of warm tires must
not be reduced.
- Adjust the tire pressure to the load you are
carrying.
- Reins tall the valve stem cap on the va lve.
When should I check the tire pr essure ?
The correct tire pressure is especially impor­
tant at high speeds. The pressure should
the refore be che cked at least once a mo nth
and always before sta rting a jo urney. Do not
f orget to c heck the ti re p ress ure for the spare
whee l
c::> page 247.
When should I adjust the tire pressures?
Adjust the t ire pr essure to the load you are
ca rrying. After cha ng ing a whee l
or replacing
whee ls you have to adjust the ti re p ress ures
on all whee ls. In addition, you m ust then
store the new tire pressures in the tire pres­
s u re monitoring system
c::> page 243 .
A WARNING
Incorrect tire pressures and/or underinfla­
tion can lead sudden tire fa ilure, loss of
control, collision, serious personal injury
or even death.
- When the warning symbol
RIJ appears in
the instrument cluster, stop and inspect
the t ires.
- Incorrect tire pressure and/or underinfla­
tion can cause increased tire wear and
can affect the handling of the vehicle and
stopping abi lity.
- Inco rrect tire pressures and/or underin ­
f lation can a lso lead to s udden t ire fail­
ure, including a blowout a nd sudden de­
f lation, ca using loss of veh icle cont ro l.
- The driver is responsible for the co rrect
tire pressures for all tires on the veh icle.
