Putting the fuel cap back on
- After filling your tank, twist the fuel fi ller cap c lockwise as
f ar as it w ill go.
- Close t he fue l fi ller flap.
To avoid fuel spi lling or evapo rating from the f uel tank a lways close
fue l filler cap properly and comp lete ly . An impro perly closed fuel
filler cap may also ca use the MIL lamp~
page 26 to come on (only
vehicle s wi th gaso lin e e ngine).
& WARNING
Improper refueling or handling of fuel can cause fire, explosion
and severe burns .
• Fuel i s highly flammable and can cause severe burns and other
injuries.
• Failure to shut the engine off while refueling and /or to insert
the pump nozzle fully into the fuel filler neck could cause fuel to spray out of filler n eck or to overflow. Fuel spray and ov erflowing
fuel can cause a fire.
• Never use a cellular telephone while refueling. The electromag­
netic radiation can cau se sparks that can ignite fuel vapors and
cause a fire.
• Never get back into your vehicle while refueling. If in excep­
tional cir cumstan ces you must get ba ck in your v ehicle while refu­
eling, make certain that you close the door and touch metal to
discharge static electricity before touching the filler nozzle again .
Static electricity can cause sparks that can ignite fuel vapo rs
released during refueling.
• Never smoke or have an open flame anywhere in o r near your
vehicle when refueling or filling a portable fue l container.
• For your safety , we strongly recommend that you do not travel
with a portable fuel container in your vehicle . The container , full
or empty may leak and could cau se a fire , especially in a crash.

Fuel supply and filling your fuel tank
& WARNING (co ntinued )
• If, under exceptional circumstances , you must tran sport a
portable fuel container, please observe the following:
-Never fill a portable fuel container while it is anywhere in or
on the vehicle (for example, in the luggage compartment, or
on the trunk ). Static electricity can build up while filling and
can ignite fuel vapors causing a fire .
- Always place a portable fuel container on the ground before
filling .
- Always keep the filler nozzle completel y inside the portable
container before and during filling.
- If filling a portable container made of metal, the filler nozzle must always be in contact with the container. This will help
prevent static ele ctricity from discharging and cause a fire .
- Ne ver spill fuel inside the vehicle or luggage compartment .
Fuel vapor s are highly flammable.
- Always observe local and state /provincial laws regarding the
use, storage and tran sportation of fuel containers .
-Make certain the fuel container meets industry standards
( ANSI / ASTM F852-86 ).

- We recommend using only coolant additive Gl2 ++ (check the
l a bel) for yo ur vehicle. This coolant ad dit ive is available at au tho·
r ized Audi dealers . Other types of antifreeze can s ignificantly
reduce corrosion protection. 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
eng ine coo lant . Adding radiator repa ir fluid may adversely affect the
function and performance of your cooling system and could result in
damage not covered by your New Vehicle Limited Warranty .•
Checking the engine coolant Level
The engine coolant level can be checked with a quick
glance .

ex pansion tank
Before you c heck anything in the eng ine compartment,
always read and heed all WARNINGS~ & in "Working in
the e ngine compartment" on
page 297.
- Turn off the ignit ion .
- Let t he eng ine cool down .
- Place a thick rag over the coolant expans ion tank
~ fig . 235 and carefully twist the cap counter ·clockwise
~ & -
Vehicle OP-eration
-Read the engine coolant level in th e open coo lant expan ·
sion tank ~ fig . 235 . With a cold engine, the coolant level
should be between the "min" and "max" ma rkings . Whe n
the engine is warm , the level may be slight ly above the
"max" marking .
The location o f the coo lant expansion tank can be seen in the engine
compartment illustration=>
page 298 .
To obt ain an accurate reading , the engine must be sw itched off.
Th e expans ion t an k in your vehicle is equippe d with an electric coolant
level sensor.
When the coolant lev el is too low, the warning light in the Auto·Check
System=>
page 30 will blink until you add coolant and t he level has
been resto red to normal. Even though there is an electric coolant
level sensor, we st ill recommend you check the coolant leve l from
time to time.
Coolant loss
Coolant loss may indicate a leak in the coo ling system . In the event of
coo lant loss , the cooling system sho uld be inspected immed iate ly by
your authorized Aud i dea ler . It is not enough mere ly to add coolant.
In a
s ealed system, losses can occu r only if the boiling point of the
coolant is exceeded as a result of ove rheating .
& WARNING
The cooling system is under pressure and can get ve ry hot. Reduce
the ri sk of scalding from hot coolant by following the se steps.
• Turn off the engine and allow it to cool down .
• Protect your face, hand s and arms from e scaping fluid and
s team b y co ve ring the cap with a large, thi ck r ag.
• Turn the cap slowly and ver y carefully in a counter-clo ckwise
direction whil e applying light , downward pre ssure on the top of
thecap .
