ASTM F852 -86) .
(D Note
Never drive yo ur vehicle until the fuel tank
is completely dry . The irregular s upply of
fue l can cause misfiring. Gasoline cou ld
enter into the exhaust system and damage
the catalytic converter.
Refuelling
The fuel filler flap is unlocked from a button
in the driver 's door .
Fig. 152 Driver 's door: Un lock ing fuel filler flap
Fig. 153 F u el cap hooked on the opened fuel filler flap
When adding fuel, the ignition and any cellu ­
lar phones in the vehicle must be sw itched
off.
Tak ing th e fuel cap off
.. To open the fuel filler flap, pull the button
¢fig . 152 .
.. Unscrew fuel filler cap counter-clockwise
and hang it on the fuel filler flap¢
fig. 153 .
.. Check the label on the inside of the fuel fi ll­
er flap to determine if the vehicle must be
fueled with gasoline or diesel fuel.
Refuell ing proc edur e
.. Insert the f uel nozzle from the gasoline
pump into the fuel fi ller neck as far as it wi ll
go .
.. Select a medium refuelling rate
so that the
nozzle switches off automatically when the
tank is full.
Putting th e fu el cap ba ck on
.. After fi lling your tank, twist the fuel filler
cap clockwise until you hear a definite click.
.. Close the fue l filler flap.
T o 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 a message in the driver
information system or cause the MIL lamp
¢page 24 to come on.
A WARNING
-Improper refue ling or handling of fuel can
cause fire, explosion and severe burns.
- Fue l is highly flammable and can cause
severe burns and other injur ies.
- Failure to shut the engine off while refu­
eling and/or to insert the pump nozzle
ful ly into the fuel filler neck could cause
fue l to spray out of filler neck or to ove r­
f low. Fue l spray and overflowing fue l can
cause a fire .
- Never use a ce ll ular telephone while re­
fue ling. The electromagnet ic rad iation
can cause sparks that can ignite fuel va­
pors and cause a fire.
- Never get back in to yo ur vehicle whi le re­
fue ling. If in exceptional circ umstances
you must get back in your vehicle while
ref ueling, make certain that you close
the door and touch metal to discharge
static electricity before touching the fill­
er nozzle again . Static e lectr icity can
cause sparks that can ignite fuel vapors

eling or fi lling a portab le fue l conta iner . ..,_

204 Checking and filling
Checking the engine coolant level
The engine coolant level can be checked with
a quick glance .
Fig. 162 Engine compartme nt: coo lant expansio n tank
Before you check anything i n the eng ine com­
partment,
a lw ays rea d and h eed all WARN­
ING S ¢&. in Working in the engine compart­
ment on page 194.
.. Park your vehicle on a level surface.
.. Turn
off the ignit ion .
.. Read the eng ine coolant leve l from the
coolant expansion tank<=>
fig. 162 . With a
cold eng ine, the coo lant level should be be­
tween the "min" and "max" markings . When
the engine is warm, the level may be slightly above the "max" marking.
The location of the coolant expansion tank
can be seen in the engine compartment illus­
tration
i:> page 196.
To obtain an accurate read ing, the engine
must be switched
off.
The expansion tank in yo ur vehicle is equipped
with an e lectric coolant level sensor .
When the coolant level is too low, the warning light in the Auto -Check System
c> page 17 w ill
blink until you add coo lant and the level has
been restored to norma l. Even though there is
an electric coolant level sensor, we still rec­
ommend you check the coolant level from
time to time.
Coolant lo ss
Coolant loss may indicate a le ak in the cooling
system . In the event of coolant loss, the cool­
ing system should be inspected immediately by your authorized Audi dea
ler .
It is not
enough merely to add coolant .
In a
se aled system, losses can occur on ly if
the boiling point of the coo lant is exceeded as
a res ult of overheating.
(D Note
Do not ad d any type of radiator leak sea l­
ant to your veh icle's engine coolant . Add­
i ng radiator repair fl uid may adverse ly af ­
fect the funct ion and performance of your
cooling system and could result in damage not covered by your New Veh icle Limited
Warranty .
Adding coolant
Be very careful when adding engine coolant.
Before you check anything in the eng ine com ­
partment,
a lw ays re a d and heed all WARN­
INGS c::> A in Working in the engine compart ­
ment on page 194 .

instead unt il you can get the correct add itive
and can restore the correct ratio. This shou ld
be done as soon as possible .
If you have lost a considerab le amou nt of
c oolant, then you sho uld add cold ant ifree ze
and co ld wate r on ly when the engine is cold.
Always use
new engine coo lant when refilling .
Do not f ill coolant above the
"MAX" mark. Ex­
cess coolant will be forced out through the
pressure relief valve in the cap when the en -
gine becomes hot .

Battery
General information
All work on the battery requires technical
knowledge!
F ig . 1 64 Eng ine co mpa rtment: Batte ry w it h cover*
The battery is located in the engine compart­
ment
c::> fig. 164 and is near ly m ain te nance­
fre e.
The condition of the battery is checked in the
framework of the inspection.
Disconnecting the battery
The batte ry should not be disconnected. Some
ve hicl e functions such as power windows are
unavailable if the battery termina ls are dis­
connected. These funct ions have to be re­
l earned after the battery term inals are con­
nected aga in. To prevent this, the battery
should only be disconnected from the vehicle
electrical system if absolutely necessary .

Vehicl es not driven for long periods and
sho rt -d is tance op eration
If you do no t drive your vehicle for several
days or weeks, electrical consumers are grad ­
u ally scaled back or switched off . This reduces
energy use and ensures the vehicle will be
able to start after long periods of time
c::, page 167. Some convenience functions
such as opening w it h the remote control key
may not be available. These conve nience func­
tions wi ll be available again once you switch
the ignit io n on and sta rt the engine. Even
whe n consume rs a re switched off, the battery
will become deeply discharged by stand -by
power consumers if the vehicle is not driven
for several months . Deep discharging results
in a chemical reaction that destroys the inside
of the battery. The battery must be charged
every month to prevent th is
c::, page 209. Do
not disconnect the battery or the anti-t heft
alarm system* will not work .
Winter operation
Cold weather places higher demands on the
battery. This results in reduced starting abili­
ty. Have the battery checked and recharged if
necessary befo re the cold weather begins.
Avoid unnecessary power consumpt ion, par­
ticularly in city traffic or when traveling only
short distances . Let your authorized Audi
dealer check the capacity of the vehicle bat­
tery before winter sets in
c::, page 209 . A well
c harged bat tery will not o nly prevent s tarti ng
problems when the weather is cold, but will
also last longer .

used today are underinflated just by looking
at them.
Therefore, be sure to check tire pressures at l eas t once a mon th and always before going
on a long trip. 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 ¢
page 220, Tires and vehicle
load limits
for more important information .
A lways use an accurate tire pressure gauge
when check ing and adjusting inflation pres­
sures . Check all of the tires and be sure not to
forget the spare t ire . If the pressure in any tire
is too high when the tire is "cold," let air out
of the tire slowly with the edge of the t ire
gauge and keep checking the pressure until
you reach the p ress ure th at is cor rect for the
l oad (passengers and luggage) and kind of
driving you plan to do .
I f the p ressu re in any tire is too low , note the
d ifference between the pressure in the cold
tire and the pressure you need and add the air
that you need to reach the correct pressure for
the vehicle load (passengers and luggage) for
the tires on your vehicle as listed on the on
your veh icle and in this manual and the kind
of dr iving you p lan to do.
Never e xceed the m aximum inflation pre s­
su re li sted on th e tir e side wall for any rea ­
son.
Remember that the vehicle manufacturer, not
the tire manufacturer, determines the co rrect
tire p ressure for the tires on your vehicle .
It is important to check the tire pressure when
the tires are cold .
- Read the requ ired ti re p ressu re from the tire
pressure label. On USA veh icles, the t ire
pressure label is located on driver's side 8-
pillar . On Canada vehicles, the tire pressure
label is located either on the driver's side 8-
pillar or inside the fuel fi ller flap.
- Turn the valve stem cap counter-clockwise
to remove it from the tire valve.
- Place the air pressure ga uge on the valve.
Tire s an d wheel s 219
- The tire pressures 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.
- Reinstall the valve stem cap on the va lve.
When should I check the tir e pressu re?
T he co rrect tire pressu re is especially impor ­
tant a t high speeds. The pressure should
therefore be checked at least once a month
and always before starting a jo urney . Do not
forget to check the tire pressure for the spare
whee l
¢page 234.
When should I adjust the tire pres sur es?
Adjus t the t ire press ure to the load you a re
carrying . After changing a whee l
or rep lacing
whee ls you have to adjust the tire pressu res
on all whee ls. In addition, yo u m ust then initi­
ali ze the new t ire pressures in the tire pres­
sure monitoring system*¢

A WARNING
...---
Incorrect tire pressures and/or underinfla-
tion can lead sudden tire fa ilure, loss of
control, collision, serio us personal injury
or even death.
- When the warning symbol
ti] appears in
the instrument cluster, stop and inspect
the t ires.
- Inco rrect tire pressure and/or underinfla­
tion can cause increased tire wea r and
can affect the hand ling of the vehicle and
s topping abi lity.
- I nco rrect tire pressures and/or unde rin­
flation can a lso lead to sudden t ire fail­
ure, including a blowou t and sudden de­
flation, ca using loss of vehicle contro l.
- The driver is responsib le for the correc t
tire pressures for all tires on the veh icle.
The applicable pressure values are locat­
ed on a sticker on the dr iver's side 8-pil­
lar or on the ins ide of the fuel filler flap. •
