-Never open the engine compartment lid if
you see or hear steam, or if you see engine coolant dripping from the engine compartÂ
ment. You could burn yourself. Let the enÂ
gine cool off first until you can no longer see
or hear steam or coo lant escaping .
CD Note
- Mount ing additional lights or accessories in
front of the a ir inlets reduces the cooling efÂ
fect of the rad iator. At h igh outside temperÂ
atures or high engine load, the engine could
ove rheat.
- The front spo ile r has been designed to propÂ
erly distribute the cooling air when the veh iÂ
cle is mov ing. If the spo iler is damaged, this
could reduce the cooling effect and the enÂ
gine could then overheat. Ask your authorÂ
ized Audi dealer for assistance.

- Methanol fuels which do not meet these reÂ
quirements may cause corrosion and damÂ
age to plastic and rubber components in the
fuel system.
- Do not use fuels that fail to meet the spec iÂ
fied criteria in this chapter.
- If you are unable to determine whether or
not a particular fuel blend meets the speciÂ
fications, ask your service station or its fuel
supplier.
- Do not use fuel for which the contents canÂ
not be identified.
- Fuel system damage and performance probÂ
l ems resulting from the use of fuels differÂ
ent from those specified are not the responÂ
sibility 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 problems due
to the use of one of these fuel blends, we
recommend that you switch to unb lended

Gasoline additives
A major concern among many auto manufacturÂ
ers is carbon deposit build-up caused by the type
of gasoline you use.
A lthough gasol ine grades differ from one manuÂ
facturer to another, they have certain things in
common. All gaso line grades contain substances
that can cause deposits to collect on vita l engine
parts, such as fuel injectors and intake valves. A lÂ
though most gasoline brands include additives to
keep engine and fuel systems clean, they are not
equally effect ive .
Audi recommends using TOP TIER Detergent GasÂ
oline. For more information on TOP TIER DeterÂ
gent Gasoline, please go to the official website (www.toptiergas .com).
152
After an extended period of using inadequate
fuels, built-up carbon deposits can rob your en gine of peak performance .

Damage or malfunction due to poor fuel qualÂ
ity is not covered by the Audi New Vehicle
Limited Warranty.
Fuel tank
· Fuel filler neck
The fuel filler neck is located on the right rear
s id e panel behind the fuel filler flap.
If the unlocking system should fail, you can still
open the flap manually -for detailed instructions
see
~page 154.
You can find the fuel tank capacity of your vehicle
i n
Technical Data .
The label on the inside of the fuel filler flap tells
you the correct fuel for your vehicle. For more inÂ
formation about fuel specifications, see
~ page 151 .
Your vehicle fue l tank has an on-board refueling
vapor recovery system. This feature helps to preÂ
vent fuel vapors from escap ing from the tank and
polluting the environment while you refuel your
vehicle. In order to fill the tank properly while
protecting the environment, please follow this
refueling procedure carefully.
& WARNING
-Under normal operating conditions, never carÂ
ry additional fuel containe rs in your car . Gas
canisters and other containers used to trans port f uel can be dangerous. Such containers,
full 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, transpo rtation
and storage of such fuel containers. Make cerÂ
tain the container meets indus try s tandar ds
(ANSI/ASTM F8S2 -86).

into the fue l filler neck cou ld cause fuel to
spray out of filler neck or to overflow. Fue l
sp ray an d overflowing fue l can ca use a fire.
- Never use a ce llular telepho ne while refuelÂ
ing . T he elec tromagnetic radiation can
cause sparks that can ignite fuel vapo rs and
cau se a fire .
- Never get back into yo ur vehicle wh ile refuÂ
e ling . If in except iona l circumst ances you
m ust get ba ck in yo ur vehicle whi le refuelÂ
i n g, make cert ain that yo u close the doo r

- For your safety, we strongly recomme nd
that you do not travel with a portable f uel
container in your veh icle. The container, f ull
or empty may leak and cou ld cause a f ire,
especia lly in a cras h .
- If, under exceptional c ircumstances, you
must t ransport a po rtab le fuel conta iner,

Fuel supply and filling your fuel tank
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 f illing.
- Always keep the fi ller nozzle comp letely
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 discharging
and cause a fire .
- Never sp ill fuel inside the vehicle or lugÂ
gage compartment. Fuel vapors are highly
f la mmab le.
- Always observe local and state/provincial
laws regarding the use, storage and transÂ
portat ion of fuel containers.
- Make certain the fuel container meets inÂ
dustry standards (ANSI/ ASTM F8S2 -86) .
(D 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 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 pollute the enviro nment.
@ Tips
- Running your engine while refueling may
cause vapors to escape or even fue l to spill
out of the tank. This would then shut off the
fuel nozzle before the tank is full.
- Do not refuel your vehicle w ith the ignition
switched on . The fuel gauge may otherwise
not indicate the correct fuel level after refuÂ
e ling.

could start a fire.
- Keep an approved fire extinguisher immeÂ
diately available .
- To avoid electrical shock and personal injury
while the engine is running or being started,
never touch:
- Ignition cables
- Other components of the high voltage
electronic ignition system.
- If you must perform a check or repair with
the engine running:
- First, fully apply the parking brake, move
selector lever of S tronic to
"N" (Neutral);
put manual transmission in Neutral.
- Always use extreme caution to prevent
clothing, jewelry, or long hair from getting
caught in the radiator fan, V-belts or other

Tires and wheels
-The use of incorrect tire presÂsure values can lead to acciÂ
dents or other damage. ThereÂ
fore it is essential that the driver observe the specified
tire pressure values for the
tires and the correct pressures
for the function of the tire pressure monitoring system.
-Always inflate tires to the rec ommended and correct tire
pressure before driving off.
-Driving with underinflated tires bend more, letting them get too hot resulting in tread
separation, sudden tire failure
and loss of control.
-Excessive speed and/overloadÂ
ing can cause heat build-up,
sudden tire failure and loss of
control.
-If the tire pressure is too low
or too high, the tires will wear
prematurely and the vehicle
will not handle well.
-If the tire is not flat and you do not have to change a wheel
immediately, drive at reduced
speed to the nearest service
station to check the tire presÂ
sure and add air as required .

d) Note
Driving without valve stem caps
can cause damage to the tire
valves. To prevent this, always
make sure that factory instalÂ
led valve stem caps on all
wheels are securely mounted on the valve.
@ For the sake of the environment
Underinflated tires will also inÂ
crease the fuel consumption.
Tires and vehicle load limits
There are limits to the amount of
load or weight that any vehicle
and any tire can carry. A vehicle
that is overloaded will not handle
well and is more difficult to stop. Overloading can not only lead to
loss of vehicle control, but can alÂ
so damage important parts of the
vehicle and can lead to sudden
tire failure, including a blowout and sudden deflation that can
cause the vehicle to crash.
Your safety and that of your pasÂ
sengers also depends on making
sure that load limits are not exÂ
ceeded. Vehicle load includes evÂ
erybody and everything in and on
the vehicle. These load limits are ...
