Parking on a slope
Do not pork on a slope with a trailer. If it cannot
be avoided, do so only ofter doing the following:
When parking:
.. Apply the foot brake .
.. Have someone place chocks under both the ve­
hicle and the trailer wheels .
.. With chocks in place, slowly release the brakes
until the wheel chocks absorb the load .
.. Turn the wheels towards the curb .
.. Apply the parking brake .
.. Move the selector lever to P.
When restarting after parking:
.. Apply the foot brake .
.. Start the engine .
.. Move the selecto r lever to D/S .
.,. Release the parking brake and slowly pull out
and away from the wheel chocks .
.. Stop and have someone retrieve the wheel
chocks.
(D Tips
If you move the selector lever of the automat­
ic transmission to P before applying the park­
ing brake and before blocking the wheels, you
may have to use more force later to move the
lever out of the P position.

Fuel and Refueling
CJ) Note
-Methanol fuels which do not meet these re­
quirements may cause corrosion and dam­
age to plastic and rubber components in the
fuel system.
- Do not use fuels that fail to meet the speci­
fied criteria in this chapter.
- If you are unable to determine whether or
not a particular fuel blend meets the speci­
fications, ask your service station or its fuel
supplier .
- Do not use fuel for which the contents can­
not be identified.
- Fuel system damage and performance prob­
lems resulting from the use of fuels differ­
ent from those specified a re not the respon­
s ibilit y 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 lems 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 manufactur­
ers is carbon deposit build-up caused by the type
of gasoline you use .
Although gasoline grades differ from one manu­
facturer to another, they have certain things in
common. All gasoline grades contain substances
that can cause deposits to collect on vita l engine
parts, such as fuel injectors and intake valves. Al­
though most gasoline brands include additives to
keep eng ine 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 in adequate
fuels, built -up carbon deposits can rob your en­
g ine of peak performance .

(D 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 your fuel tank .
Refueling
Fuel filler neck
The fuel filler neck is located on the right rear
s ide panel behind the fuel filler flap .
If the power locking system should fail , you can
still open the flap manually -for detailed instruc ­
tions see
Q page 176.
You can find the fuel tank capacity of your vehicle in
¢ page 230.
The label on the inside of the fuel fi ller flap tells
you the correct fuel for your vehicle. For more in­
formation about fuel specifications, see
¢ page 173.
Your vehicle fuel tank has an on-board refueling
vapor recovery system. This feature helps to pre­
vent fuel vapors from escaping from the tank and polluting the envi ronment while you refuel your
vehicle . In order to fill the tank properly while
protect ing the env ironment, please follow this
refueling procedure carefully.
A WARNING
Under normal operat ing conditions, never ca r­
ry additional fu el containers in your car. Gas
canisters and other containers used to trans­
port fue l can be dangerous . Such containers,
fu ll or empty, may leak and could cause a fire
in a collision. 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
tai n the container meets industry standards
(ANSI/ASTM F8S2 -86) .

Putting the fuel cap back on
• After fi lling your tank, twis t the fuel c ap cloc k-
w ise as far as i t will go.
• Close the fue l filler flap .
T o avo id f uel spilling or evaporat ing from the fuel
tank always close f ue l cap prope rly and com­
pletely . An im properly closed f uel fi ller cap may
also cause the MIL lamp¢
page 25 to come on.
A WARNING
- -
Improper refueling or handling of f ue l can
cause fire, explosion and severe burns .
- Fue l is highly flammable and can cause se ­
vere burns and other injuries.
- Fa ilure to shut the engine
off while refue l­
ing and/or to inse rt the pump nozzle f ully
into the f ue l filler neck cou ld cause fuel to
spray out of fi ller neck or to overflow. Fue l
spray and ove rflowing fuel can cause a f ire.
- Never use a cellular telephone while refue l­
i n g . The electromagnetic rad iat io n can
cause sparks t hat can ignite fuel vapors and
cause a fire.
- Never get back into yo ur vehicle whi le refu­
eling . If in excep tional circ umstances you
m ust g et ba ck in yo ur vehicle wh ile refuel­
i n g, make certa in tha t yo u close the doo r

- Never smo ke or have an open flame any­
where i n or near your vehicle when ref ueling
or fi lling a portab le fuel container.
- For your safety, we strong ly recommend
that you do not trave l w ith a portable fuel
container in your veh icle. The container, full
or empty may leak and co uld cause a fire,
especia.lly in a crash.
- If , under except ional circumstances, you

Fuel and Refueling
while filling and can ignite fuel vapors
causing a fire.
- Always p lace a portable fuel container on
the ground before filling.
- Always keep the filler nozzle completely
inside the portable container before and
during filling.
- If filling a portable container made of
metal, the filler nozzle must a lways be in
contact with the container . This will help
prevent static electricity from discharging
and cause a fire .
- Never spill fuel inside the vehicle or lug­
gage compartment. Fuel vapors are highly
flammable .
- Always observe local and state/provincial
laws regarding t he use, storage and trans­
portation of fuel containers .
- Make certa in the fuel container meets in­
dustry standards (ANSI/ ASTM
F852-86) .
CD Note
If any fuel has spilled onto the car, it should
be removed immediately to prevent damage
to the paint.
@ For the sake of the environment
As soon as the correctly operated nozz le
switches off automatically for the first time ,
the tank is full. Do not try to add more fuel
because fuel may spill out . In addition, the
expansion space in the fuel tank will be filled -
causing the fuel to overflow when it becomes
wa rm and pollute the environment.
(0 Tips
- Running your engine while refueling may
cause vapors to escape or even cause fuel to
sp ill out of the tank. This would then shut
off the fuel nozzle before the tank is full.
- Do not refuel your vehicle with the ignition
turned on. The fuel gauge may otherwise
not indicate the correct fue l level after refu­
eling.
- The fuel filler flap of your vehicle is not
l ocked when you lock the veh icle from the
inside.

Check ing and F illing
The location of the coolant expansion tank can be
seen in the engine compartment illustration
c::> page 179.
To obtain an accura te reading, the eng ine must
be switched off .
The expans io n tank in your vehicle is equipped
with a n elec tric coolant level sensor.
When the coolant level is too low, the war ning
lig ht in the Auto-Check System
c::> page 14 will
blin k until you add coo la nt and the level has bee n
restored to normal. Even t hou gh the re is an e lec­
tr ic coolant level sensor, we still re commend you
check the coo lant level from time to time .
Coolant loss
Coolant loss may indicate a leak in the cooling
system. I n the event of coolant loss, the cooling
system should be inspected immediately by your
author ized Audi dealer. It is not enough me rely
to add coolant.
I n a
se aled system, losses can occur only if the
boi ling point of the coo lant is ex ceeded as a re ­
sul t of over heat ing.
A WARNING
T he cooling system is unde r pressure and can
get very hot . Red uce the risk of scalding from
hot coolant by following these steps.
- Turn off the eng ine and a llow it to cool
down .
- Protect your face, hands and arms from es ­
caping fluid and steam by cove ring the ca p
with a la rge, thick rag.
- Turn the cap s lowly and very ca refu lly in a
counter-clockwise direction w hile ap ply ing
light, downwa rd pressure o n the top of the
cap.
- To avo id being burned, do not sp ill anti­
freeze or coolant on the exha ust system or
hot eng ine parts. Under certain conditions,
the ethy lene g lycol in e ngine coolant can
catch fire.
(D Note
Do not add any type of radiato r leak sealant
to your veh icle's engine coolant. Adding radia-

A WARNING ,~
- The cooling system is under pressure and
can get very hot. Reduce the risk of scald ing
from hot coolant by following these steps.
- Turn
off the engine and allow it to coo l
down.
- Protect you r face, hands and arms from
escaping fluid and steam by cover ing the
cap with a large, thick rag.
- Turn the cap slowly and very carefully in a
counter-clockwise d irection while applying
light, downward p ressure on the top of
the cap.
- To avoid being burned, do not spill anti­
freeze or coolant on the exhaust system or
hot engine parts. Under certa in cond i­
tions, the ethylene glycol in eng ine cool­
ant can catch fire.
- Antifreeze is poisonous. Always store anti­
freeze in its orig inal container and well out
of the reach of children.
- If you dra in the coolant, it must be caught
and safely stored in a proper conta iner
clearly marked "poison".
- Do not add coolant if the expansion tank is
empty. Air cou ld enter the cooling system
and damage the eng ine. If this is the case,
do not continue driving . Seek professional
ass istance.
- Coolant pollutes the env ironment and could
cause an eng ine fire. Excess coolant will be

Checking and Filling
Brake fluid
Checking brake fluid level
The brake fluid level can be checked with a quick
glance.
Fig. 153 Eng ine compartment: Cover on the brake fluid
r eservoir
Before you check anything in the engine compart­
ment,
always read and heed all WARNINGS
¢ A in Working in the engine compartment on
page 177.
., Read the brake fluid level from the brake fluid
reservoir
<=> fig . 153, ¢page 179, fig . 149 . The
brake fluid level must be between the
" MIN"
and "MAX " markings.
The brake fluid reservoir is located at the rear
partition of the engine compartment on the left
side ¢
page 179 .
The fluid level may drop slightly after some time
due to the automatic adjustment of the brake
pads . This is not cause for alarm .
If the brake fluid level falls
considerably below
the ' 'MIN" mark, the brake warning/indicator
light (USA models:
1111 , Canada models:. )
will come on¢
page 13 . Do not continue to oper­
ate the vehicle . The complete brake system
should be thoroughly checked by an authorized
Aud i dealer or qualified workshop and the cause
corrected. If the brake fluid level is too low, the
brake warning/indicator light w ill illuminate.
Contact an author ized Audi dealer
immediately.
(D} Tips
The brake fluid reservoir is located under­
neath the cover.
186
Changing brake fluid
Have the brake fluid changed by an experienced
technician .
Brake fluid absorbs moisture from the air. If the
water content in the brake fluid is too high, cor­
rosion in the brake system may result after ape­
riod of time . The boiling po int of the brake fluid
will a lso decrease considerably and decrease
braking performance.
Therefore , the brake fluid must be changed
every
two years .
Always use new brake fluid which con­
forms to Feder-al Motor Vehicle Standard "FMVSS
116 DOT 4 ".
The brake fluid reservoir can be difficult to reach ,
therefore, we recommend that you have the
brake fluid changed by your author ized
Audi
dealer .
Your dealer has the correct tools, the
right brake fluid and the know-how to do this for
you.
A WARNING
- Brake fluid is poisonous. It must be stored
only in the closed original container out of
the reach of children!
- Brake fai lure can result from o ld or inappro­
priate brake fluid. Observe these precau­
tions:
- Use only brake fluid that meets SAE speci­
fi cation
J 1703 and conforms to Federal
Motor Veh icle Standard 116. Always check
with your authorized Audi dealer to make
sure you are using the correct brake fluid .
The correct type of brake f luid is also indi­
cated on the brake fluid reservoir.
- The brake fluid must be new . Heavy use of
the brakes can cause a vapor lock if the
brake fluid is left in the system too long .
This can seriously affect the efficiency of
the brakes as well as your safety. This
could result in an accident.
(D Note
Brake fluid will damage the paint of your vehi-

Wheels
and a special procedure. You must not repair or
disassemble them¢&. .
A WARNING
Wheel bolts that are tightened or repaired in­
correctly can become loose and result in loss
of vehicle control, which increases the risk of
an accident. For the correct t ightening specifi ­
cation, refer to ¢
page 214, After changing a
wheel .
- Always keep the wheel bolts and the
threads in the wheel hub clean and free of grease.
- Only use wheel bolts that fit the rim .
- Always have damaged rims repaired by an
authorized Audi dealer or authorized Aud i
Service Facility . Never repair or disassemble
rims yourself, because this inc reases the risk
of an accident.
Winter tires
Winter tires s ignificantly improve the vehicle's
handling when driving in winter conditions . Be­
cause of their construction (width, compound,
tread pattern), summer tires provide l ess trac­
tion on ice and snow.
.,. Use winter tires on all four wheels.
.,. Only use winter tires that are approved for your
vehicle.
.,. Please note that the maximum permitted
speed may be lower with winter tires
q .&,. . An
authori zed Audi dealer or authori zed Audi Serv­
ice Facility can inform you about the maximum
permitted speed for your tires .
.,. Check the tire pressure after install ing wheels
q page 201.
The effectiveness of winter tires is reduced great­
ly when the tread is worn down to a depth of
0 .157 inch (4 mm). The character istics of winter
tires also decrease greatly as the tire ages, re­
gardless of the remaining tread.
A WARNING
- Never drive faster than the maximum per­
mitted speed for your tires. This cou ld cause
the tires to heat up too much. This increases
206
-
the risk of an accident because it can cause
the tire to burst.
- Always adapt your driving to the road and
traffic conditions . Drive carefully and reduce
your speed on icy or slippery roads . Even
winter tires can lose traction on black ice .
@ For the sake of the environment
Reinstall summer tires at the appropriate
time, because they prov ide better handling
when roads are free of snow and ice. Summer
tires cause less road noise, tire wear and fuel
consumpt ion .
(D Tips
You can also use all season tires instead of
winter tires. Please note that in some coun­
tries where winter tires are required, only
winter tires w ith the ~ symbol may be per­
mitted.
Snow chains
Snow chains improve traction in the snow .
.,. Only install snow chains on the front wheels.
This applies also to vehicles with all wheel
drive* .
.,. Check and correct the seating of the snow
chains if necessary after driving a few feet. Fol­
low the instructions from the manufacturer.
.,. Note the maximum permitted speed when dr iv­
ing with snow chains. Do not exceed 30 mph (SO km/h).
Snow cha ins not only improve the
driving in win­
ter road conditions, but also the
braking .
Use of snow chains is only permitted with certain
rim/tire combinat ions due to technical reasons .
Check with an author ized Audi dealer or author­
ized Audi Service Facility to see if you may use
snow chains.
The snow chains must have
low-profile links and
must not be thicker than 0.53 inch (13.5 mm),
including the lock.
You must remove the chains when driving on
roads that are
free of snow . When roads are free ..,.
