A WARNING
Improper refueling or handling of fuel can
cause fire, explosion and severe b urns.
-
- Fuel is highly flammable and can cause se­
vere burns and other injur ies .
- Failure to shut the engine off wh ile refuel ­
ing and/or to insert the pump nozz le fully
into the fuel filler neck could ca use fue l to
spray out of filler neck or to ove rflow. Fuel
spray and overflowing fue l can cause a fire.
- Never use a cellular telephone wh ile refuel­
ing. The electromagnetic radiation can
cause spa rks that can ignite f uel vapors and
cause a fire .
- Never get back into your vehicle while refu­
eling. If in except ional circumstances you
must get back in your vehicle while refuel­
ing, make certain that you close the door
and touch meta l to discha rge static ele ctric­
ity befo re touching the filler noz zle ag ain.
Fuel and R efueling
Stat ic electricity can cause sparks that can
ignite fue l vapors released during refueling.
- Never smo ke or have an open flame any ­
where in or near your vehicle when ref ueling
or filling a portable fuel container .
- For your safety, we strongly recommend
that you do not trave l with a po rtable fuel
container in your veh icle. The container, fu ll
or empty may leak and co uld cause a fire,
especially in a crash .
- If, under except ional circumstances, you
m ust transport a portable fuel container,
p lease observe the following:
- Never fill a portab le fue l conta iner while it
is anywhere in or on the vehicle (for exam­
ple, in the l uggage compa rtment, o r on
the trunk). Static electricity can build up
while filling and can ignite fuel vapors caus ing a f ire .
-Always place a portab le fue l conta iner on
the ground before fi lling .
-A lways keep the f iller nozzle comp lete ly
inside the portable container before and
during f il li ng.
- If filling a portable conta iner made of
metal, the filler nozz le must always be in
contact with the container . This will he lp
prevent stat ic elec trici ty from discharging
and ca use a fire .
- Never spill fue l inside the vehicle o r lug­
gage compartment. F uel vapors a re highly
flammable .
- Always observe loca l and state/prov incial
laws rega rding the use, storage a nd trans­
po rtation of fuel contai ners.
- Make ce rtain the f uel con tainer mee ts i n­
dust ry standards (A NSI/ AS TM F852 -86) .

Cooling system
Coolant
The engine coolant performs two functions: it
keeps the engine from overheating and it pro ­
tects the engine from freezing in the winter .
The cooling system is sealed and generally re­
quires little attention.
T he cooling system has been filled at the factory
with a permanent coolant which does not need to
be changed . The coolant consists of a mixture of
specially condit ioned water and the manufactur ­
er's glycol-basedcoolant add itive G 13 antifreeze
with anticorrosion additives (SO% for USA mod­
e ls; 60% for Canadian mode ls). This m ixture
both ass ures the necessa ry frost protection and
protects metal components in the engine's coo l­
ing system from corrosion and scaling .
It also
raises the boiling point of the coolant.
Do not red uce the concent ration of the coolant in
the summer by adding p lain water.
The propor­
tion of coolant addit ive mu st be at least 50 %
but not more than 60 %
to mainta in antifreeze
protection and cooling efficiency. If the coolant
frost protection is too low, the coolant could
freeze and damage the vehicle heating and en­
g ine cooling system .
For year-round driving, antifree ze is added at the
factory for temperatures down to :
- -31° F(- 3S°C)USA
- - 40 ° F ( - 40 °C) Canada.
If you must add coolant, use a m ixture of water
and coolant addit ive. M ixing the coolant additive
with d istilled water is recommended .
_& WARNING
Before you check anythi ng i n t he engine com­
partment, always read and heed all WARN ­
INGS
¢ .&. in Working in the engine compart­
ment on page 193 .
(D Note
-Befo re winter se ts in, have the coo lant
checked to see if the coolant additive in your
vehicle is sufficient to meet the cl imate con -
Check ing and Filling
ditions. This is especially important if you
live in a region where the winter is extreme­
ly cold. If necessary, increase the proportion
of coolant additive to 60%.
- When adding coolant additive to your cool­
ing system, remember :
- We recommend us ing only coolant add i­
tive G12+ + or G13 for yo ur vehicle. This
coolant addit ive is avai lab le at aut horized
A udi dealers . O ther types of antifree ze can
significantly reduce corrosion pro tect ion .
The resulting corrosion can cause a loss of
coolant and serious engine damage.
- Do not add any type of radiator leak sealant
to your vehicle's engine coolant. Adding ra ­
diator repair fluid may adversely affect the
function and performance of your cooling system and cou ld resu lt in damage not cov­
ered by your New Veh icle Limited Warra nty .
Checking the engine coolant level
The engine coolant level can be checked with a
quick glance.

ommend that you have the brake fluid
changed by your authorized Audi dealer .
Battery
General information
Under normal operating conditions, the battery
in your Audi does not need any maintenance.
With
high outside temperatures or long daily
drives we recommend that you have the electro­
lyte level checked by an authorized Audi dealer or
qualified workshop. The electrolyte level should
also be checked each time the battery is charged
¢ page 205.
Have the battery checked when you take your ve­
hicle in for serv ice. You are well advised to re­
place a battery t hat is older than 5 years.
Disconnecting the battery terminals
Some vehicle functions (power window regula­
tors, for example) are lost if the battery termi­ nals are disconnected. These functions have to be
relearned after the battery terminals are con­
nected again. To prevent th is, the battery should
only be disco nnected from the vehicle e lectr ica l
system when abso lutely necessary for repairs.
Vehicles not driven for long periods
If you do not drive your vehicle over a period of
several days or weeks, electrical components are
gradually cut back or sw itched off. This reduces
energy consumption and maintains starting ca ­
pability over a longer period¢
page 173.
Some of the conven ience functions may not oper­
ate, such as the interior lights or the power seat
adjustment. The convenience functions will be
available again when you turn on the ignition and
start the engine.
Winter operation
During the winter months, battery capacity tends
to decrease as temperatures drop . T his is be-
Checking and Filling
cause more power is also consumed while start­
ing, and the headlights, rear window defogger,
etc., are used more often.
Avo id unnecessary power consumption, particu­
larly in city traff ic or when traveling only short
distances . Let your authorized Audi dealer check
the capacity of the vehicle battery before winter
sets in ¢
page 205. A well charged battery will
not only prevent starting problems when the
weather is cold, but will also last longer .
(D Tips
If your vehicle is left standing for several
weeks at extremely low temperatures, the ve­
hicle battery should be removed and stored
where it w ill not freeze. This will prevent it
from be ing damaged and having to be re­
placed.
Working on the battery
Be especially careful when working on or near
the battery.
The battery is located in the luggage compart­
ment under the floo r. Before you check anything
in the luggage compartment,
read and heed all
WARNINGS ¢
LD.·
Always heed the safety warnings, when working
on the vehicle battery or the veh icle electrical
system to prevent injury.
The following WARNINGS are very important
when working on the battery:

Intelligent energy management in your vehicle is
responsible for dist ributing the electrical energy
throughout your vehicle¢
page 173. The inte lli­
gent ene rgy ma nagement system wi ll keep the
eng ine batte ry charged better the n ve hicles w ith­
ou t th is system . To make su re the addit io nal
e lec trica l energy is avail ab le on ce again after you
h a ve changed the battery, we recommend t hat
you insta ll batteries o f the same type an d manu­
facture on ly (t he same as those insta lled at the
time your veh icle was delive red). Spec ificat ions
are listed on the battery housing. Your author­
ized Audi dealer must code the battery in the en­
ergy management system to enab le you to use
the energy manageme nt functions correctly after
replacing the battery .
If it is not possible to use a battery of th is type,
the new battery must have the same capacity ,
voltage (12-volts) , ampe rage, construct ion and
p lug sealing.
When insta lling the battery, make sure the igni­
tion and all electrical consumers are tur ned off .
@ Note
Make sure the ventilation hose on the side of
the batte ry is connected, othe rw ise fumes or
battery acid can lea k out.
@ For the sake of the environment
Because of the prob lem of proper disposal of
a battery, we recommend your author ized

New tires or wheels
Audi recommends having all work
on tires or wheels performed by
an authorized Audi dealer or au­
thor ized Audi Service Facility.
These facilit ies have the proper
knowledge and are equipped with
the required tools and replace­ ment parts.
.,. New tires do not yet have the
optimum gripping properties .
Drive carefully and at moderate
speeds for the first 350 miles
(500 km) with new tires.
1>-Use ti res of the same construc­
tion , size (rolling circumference)
and as close to the same tread
pattern as possible on all four
wheels.
1>-0o not replace tires individually.
At least replace both tires on the
same axle at the same time.
1>-Audi recommends that you use
Audi Original Tires. If you would like to use different tires, please
note that the tires may perform
differently even if they are the
same size ¢
.&..
214
1>-Ifyou would like to equip your
vehicle with a tire/rim combina­
tion that is different from what
was installed at the factory, con­
sult with an authorized Audi
dealer or authorized Audi Service Facility before making a pur­
chase ¢,&. .
The spare tire* is different from
the regular tires installed on the
vehicle -for example, if winter
tires or wide tires are installed -
so only use the spare tire* tempo­
rarily in case of emergency and
drive carefully while it is in use. It
should be replaced with a regular
tire as soon as possible.
On
all wheel drive vehicles, all
four wheels must be equipped
with tires that are the same brand and have the same construction
and tread pattern so that the
drive system is not damaged by
different tire speeds . For this rea­
son, in case of emergency , only
use a spare tire* that is the same
circumference as the regular
tires.
! WARNING
- Only use tire/rim combina­
tions and suitable wheel bolts
that have been approved by .,.

Wheels
1/16 inch (1.6 mm) high and are
spaced evenly around the tire per­ pendicular to the running direc­
tion
¢fig . 179. The letters "TWI"
or triangles on the tire sidewall
indicate the location of the tread­
wear indicators.
The tires have reached the mini­
mum tread depth
l) when they
have worn down to the treadwear
indicators. Replace the tires with
new ones
¢ .&. .
Tire rotation
Rotating the tires regularly is rec­
ommended to ensure the tires
wear evenly. To rotate the tires;
install the tires from the rear axle
on the front axle and vice versa.
This will allow the tires to have
approximately the same length of
service life.
For unidirectional tires, make
sure the tires are installed accord­
ing to the running direction indi­
cated on the tire sidewall
¢page 233.
Hidden damage
Damage to tires and rims can of­
ten occur in locations that are

hidden. Unusual vibrations in the
vehicle or pulling to one side may indicate that there is tire damage .
Reduce your speed immediately.
Check the tires for damage. If no
damage is visible from the out­
side, drive slowly and carefully to
the nearest authorized Audi deal­
er or authorized Audi Service Fa­
cility to have the vehicle inspect­
ed.
_&. WARNING
Tread that has worn too low or different tread depths on the
tires can reduce driving safety.
This can especially have a nega­
tive effect on handling, on the
risk aquaplaning when driving
through water, when driving
through curves and when brak­ ing, which increases the risk of
an accident.
