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 .
174
(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) .

Cooling system
Coolant
The 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.
T he cooling system has been filled at the factory
with a permanent coolant which does not need to
be changed . The coolant consists of a mixture of
specially condit ioned water and the manufactur ­
er's glycol-basedcoolant add itive G 13 antifreeze
with anticorrosion additives (SO% for USA mod­
e ls; 60% for Canada models) . This mixt ure bot h
assures the necessary frost protec tion and pro­
tects meta l components in the engine's cooling
system from corrosion and scaling . It also raises
the boiling point of the coolant.
D o not red uce the concent ration of the coolant in
the summer by add ing p la in water.
The propor­
tion of coolant addit ive mu st be at least 50 %
but not more than 60 %
to mainta in antifreeze
protection and cooling efficiency. If the coolant
frost protection is too low, the coolant could
freeze and damage the vehicle heating and en­
g ine cooling system .
For year-round driving, antifree ze is added at the
factory for temperatures down to :
- -31° F(- 3S°C)USA
- -4 0 ° F ( - 40 °C) Can ada.
If you must add coolant, use a m ixture of water
and coolant addit ive. M ixing the coolant additive
with d istilled water is recommended .
_& WARNING
Before you check anythi ng i n t he engine com­
partment, a lways read and heed a ll WARN ­
INGS
¢ .&. in Working in the engine compart­
ment on page 177 .
(D Note
-Befo re winter se ts in, have the coo lant
checked to see if the coolant additive in you r
vehicle is sufficient to meet the cl imate con -
Check ing and Filling
ditions. This is especially important if you
live in a region where the winter is extreme­
ly cold. If necessary, increase the proportion
of coolant additive to 60%.
- When adding coolant additive to your cool­
ing system, remember :
- We recommend us ing only coolant add i­
tive G12+ + or G13 fo r yo ur vehicle. This
coolant addit ive is avai lab le a t aut horized
A udi dealers . O ther types of antifree ze can
significantly reduce corrosion pro tect ion .
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 engine coolant. Adding ra ­
diator repair fluid may adversely affect the
function and performance of your cooling system and cou ld resu lt in damage not cov­
ered by your New Veh icle Limited Warra nty .
Checking the engine coolant level
The engine coolant level can be checked with a
quick glance.

@ For the sake of the environment
Because of the problem of proper disposal of
brake fluid as we ll as the special toots re­
quired and the necessary expertise, we rec­
ommend that you have the brake fluid
changed by your authorized Audi dealer .
Battery
General information
Under normal operating conditions, the battery
in your Audi does not need any maintenance.
With
high outside temperatures or long daily
drives we recommend that you have the electro­
lyte level checked by an authorized Audi dealer or
qualified workshop. The electrolyte level should
also be checked each time the battery is charged
c> page 189.
Have the battery checked when you take your ve­
hicle in for serv ice. You are well advised to re­
place a battery t hat is older than 5 years.
With certain types of airbag deployment, the battery is disconnected from the vehicle electri­
cal system for safety reasons
c> & in Repair, care
and disposal of the airbags on page 125 .
Disconnecting the battery terminals
Some vehicle functions (power window regula­
tors, for example) are lost if the battery termi­ nals are disconnected. These functions have to be
relearned after the battery terminals are con­
nected again. To prevent th is, the battery should
only be disconnected from the vehicle e lectr ica l
system when abso lutely necessary for repairs.
Vehicles not driven for long periods
If you do not drive your vehicle over a period of
several days or weeks, electrical components are
gradually cut back or sw itched off. This reduces
energy consumption and maintains starting ca­
pability over a longer pe riod
c> page 157.
Some of the conven ience functions may not oper­
ate, such as the interior lights or the power seat
adjustment. The convenience functions will be
available again when you turn on the ignition and
start the engine.
Checking and Filling
Winter operation
During the winter months, battery capacity tends
to decrease as temperatures drop . This is be­
cause more power is also consumed while start­
ing, and the headlights, rear window defogger,
etc., are used more often.
Avo id unnecessary power consumption, particu­
larly in city traffic or when traveling only short
distances . Let your authorized Audi dealer check
the capacity of the vehicle battery before winter
sets in
c> page 189. A well charged battery will
not only prevent starting problems when the
weather is cold, but will also last longer .
(D Tips
If your vehicle is left standing for several
weeks at extremely low temperatures, the ve­
hicle battery should be removed and stored
where it w ill not freeze. This will prevent it
from be ing damaged and having to be re­
placed.
Working on the battery
Be especially careful when working on or near
the battery.
The battery is located in the engine compart­
ment . Before you check anything in the engine
compartment ,
read and heed all WARNINGS
c>,& ,
Always heed the safety warnings, when working
on the vehicle battery or the veh icle electrical
system to prevent injury.
The following WARNINGS are very important
when working on the battery:
Always heed the following WARNING SYM·
BOLS and safety precautions when working on
the battery.
®
Always wear eye protection.

Check ing and F illing
CJ) Note
Never use a fast charger as a booster to start
the engine . This will serious ly damage sensi­
tive electronic components, such as control
units, relays, radio, etc., as well as the battery
charger.
Battery replacement
The new battery must have the same specifica­
tions and dimensions as the original equipment
battery .
Intelligent energy management in your vehicle is
responsible for distributing the electrical energy
throughout your vehicle
¢ page 157. The intelli ­
gent energy management system wi ll keep the
engine battery charged better then veh icles w ith­
out this system. To make sure the addit ional
e lectrica l energy is available once again after you
have changed the battery, we recommend that
you install batteries of the same type and manu­
facture only (the same as those installed at the
time your veh icle was delivered). Specifications
are listed on the battery housing. Your author­
ized Audi dealer must code the battery in the en­
ergy management system to enable you to use
the energy manageme nt functions correctly after
replacing the battery.
If it is not possible to use a battery of this type,
the new battery must have the same capacity,
voltage (12-volts), amperage, construction and p lug sealing.
When installing the battery, make sure the igni­
tion and all electrical consumers are turned off.
@ Note
Make sure the ventilation hose on the side of
the battery is connected, otherw ise fumes or
battery acid can leak out.
@ For the sake of the environment
Because of the problem of proper disposal of
a battery, we recommend your authorized
Audi dea ler change the battery for you. Bat­
teries contain sulfuric ac id and lead and must
always be disposed of properly in compliance
190
with all environmenta l regulations. Disposing
of vehicle batteries improperly is very danger­
ous to the environment.

anti-freez ing agent shou ld be added to t he water
so that it does not freeze .
(D Note
-The concentration of anti-freezing agent
must be adjusted to the vehicle operating
conditions in the respective climate. A con­
centration that is too high can lead to vehi­
cle damage.
- Never add radiator anti-freeze or other addi­
t ives to the washer fluid.
- Do not use a glass cleaner that contains
paint solvents, because th is could damage
the paint.
