Cleaning and protec tion
Engine compartment
Be especially careful when cleaning the en­
gine compartment.
A lw ays switch o ff the ign it ion before cle an ­
i ng the eng ine
c> ,& .
Plenum pan el
Remove leaves from the plenum panel in front
of the windshield under the engine hood. This
prevents the water drain holes from becoming
blocked, and it prevents debris from enter ing
the vehicle interior through the heating and
vent ilat ion ducts.
Co rro sio n protect ion
The engine compartment and transmission
have been corrosion-protected at the factory.
Good anti -corrosion treatment is very impor­
tant, partic ularly in the winter.
If the vehicle
is frequently driven on salt treated roads, the
entire engine compartment and p lenum panel
should be thoroughly cleaned at the end of
winter and retreated to prevent salt damage.
At the same time, the underside of the vehicle
shou ld be washed as well.
If the engine compartment is cleaned at any
time with grease remov ing solutions
1> , or if
you have the engine washed, the anti-corro­
s ion treatment is almost always removed as
well.
It i s therefo re essentia l to have a long­
lasti ng cor rosion pro tect ion reapplied to all
surfaces, seams, joints and components in the
engine compartment .
A WARNING
Be aware: The engine compartment of any
motor vehicle is a potentially hazardous
area.
- Before work ing in the engine compart­
ment, be sure to read the information
c>page 194.
- Before reaching into the front plenum
panel, a lways remove the ignit ion key.

Sea sonally adju sted ga soline
Many gaso line g rades are blended to perform
espec ia lly we ll for winte r or summe r d riv ing .
Du ring seasonal change-ove r, we suggest that
you fill u p at busy gas s tat ions where the sea­
sona l adjus tment is more likely to be made in
time .
(CT) Note
-Methanol fuels which do no t mee t these
r equirements may cause co rrosion and
damage to plastic and rubber compo ­
nents i n the fuel system .
- Do no t use fue ls that fai l to meet the
spec ified criteria in this chapter.
- If yo u are unable to de term ine whether
or not a particular fue l blend meets the
specifications, ask your service station or
i ts fuel s upplier.
- Do not use fue l for which the contents
cannot be identified.
- Fuel sys tem damage and performance

- If you experience a loss of fue l economy
or driveability and performance prob­ l ems due to the use of one of these fuel
blends, we recomme nd that yo u sw itch
to unblended fuel.
Gasoline additives
A majo r concern among ma ny auto manufac ­
turers is carbon deposit build -up caused by
the type of gasoline you use .
A lthough gasoline grades differ from one
manuf acturer to anothe r, they h ave certa in
things in common. All gaso line g rades contain
substances that can cause deposits to co llect
on vital engine parts, such as fuel injectors
and intake valves. Although most gasoline
brands incl ude additives to keep engine and fuel systems clean, they a
re not equally effec­
tive .
A udi re commends using TOP TI ER De tergent
Gasoline. For mo re info rmat ion on TO P TI ER
Detergent Gasoline, please go to the official
website (www.toptiergas.com).
After an extended period of using inadeq uate
f uels, bui lt-up carbon deposi ts can rob yo ur
engine of peak performance.

-For your safety, we strongly recommend
that you do not travel with a portable
fuel container in your vehicle. The con­
tainer, full or empty may leak and could
cause a fire, especially in a crash.
- If, under exceptional circumstances, you
must transport 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 compart­
ment, or on the trunk) . Static electrici­
ty can build up while filling and can ig­
nite fuel vapors causing a fire.
- Always place a portable fuel container
on the ground before filling .
-Always keep the filler nozzle complete­ ly 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 electricity from dis­
charging and cause a fire.
- Never spill fuel inside the vehicle or
luggage compartment. Fuel vapors are
highly flammable.
- Always observe local and state/provin­
cial laws regarding the use, storage
and transportation of fuel containers.
- Make certain the fuel container meets
industry standards (ANSI/ ASTM
F852-86).
(D Note
- If any fuel has spilled onto the car, it should be removed immediately to pre­
vent damage to the paint.
- If the fuel tank runs completely empty in
a vehicle with a
diesel engine, the igni­
tion must remain switched on for at least 30 seconds after refueling before
starting the engine.
It may take longer
than usual for the engine to start, even
up to a minute. This is because the air
must first bleed out of the fuel system
when starting the engine.
Fuel supply and filling your fuel tank 193
@) For the sake of the environment
As soon as the correctly operated nozzle
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 warm and pol­
lute the environment.
(0 Tips
-Running your engine while refuelling
may cause vapors to escape or even fuel
to spill out of the tank. This would then
shut off the fuel nozzle before the tank
is full.
- Do not refuel your vehicle with the igni­
tion switched on. The fuel gauge may
otherwise not indicate the correct fuel
level after refuelling.
Unlocking the fuel filler flap by hand
You can open the fuel filler flap by hand if the
power locking system should fail.

Engine cooling system
Coolant
T he 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.
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 water and the manufacturer's gly­
col-based coolant additive Gl2++ antifree ze
with anticorrosion additives (50% for USA models; 60% for Canadian models). This mix ­
ture both assures the necessary frost protec­
tion and protects metal components in the
engine 's cooling system from corrosion and
scaling.
It also raises the boiling point of the
coolant.
Do not reduce the concentration of the cool­
ant in the summer by adding plain water.
The
proportion of coolant additive must be at
least 50% but not more than 60%
to main­
tain antifreeze protection and cooling efficien­
cy. If the coolant frost protection is too low,
the coolant could freeze and damage the vehi­
cle heating and engine cooling system.
Checking and filling 203
For year-round driving, antifreeze is added at
the factory for temperatures down to:
--31°F(-35°C)USA
- - 40 °F ( - 40 °C) Canada.
You can mix the Gl2 ++ coolan t additive with
other additives Gl2 + or Gl2. Always check
with your authorized Audi dealer .
A WARNING
-
Before you check anything in the engine
compartment, always read and heed all
WARNINGS~
& in Working in the engine
comportment on page 194.
(D Note
- Before winter sets in, have the coolant
checked to see if the coolant additive in
your vehicle is sufficient to meet the cli­
mate conditions. This is especially impor­
tant if you live in a region where the
win­
ter is extremely cold. If necessary, in­
crease the proportion of coolant additive
to 60% .
- When adding coolant additive to your
cooling system, remember :
- We recommend using only coolant ad­
ditive G 12++ (check the label) for your
vehicle. This coolant additive is availa­
ble at authorized Audi dealers. Other
types of antifreeze can significantly re­
duce corrosion protection. The result­
ing corrosion can cause a loss of cool­
ant and serious engine damage.
- Do not add any type of radiator leak seal­
ant to your vehicle's engine coolant.
Adding radiator repair fluid may adverse­ ly affect the function and performance of
your cooling system and could result in
damage not covered by your New Vehicle
Limited Warranty.

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 .

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

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

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
