@ Tips
It may take longer to start the engine
when the outside temperature is very cold.
If possible, use winterized fuel if tempera­
tures are below freezing.
Gasoline additives
A major concern among many auto manufac­
turers is carbon deposit build-up caused by
the type of gasoline you use.
Although gasoline grades differ from one manufacturer to another, they have certain
things in common. All gasoline grades contain
substances that can cause deposits to collect
on vital engine parts, such as fuel injectors
and intake valves. Although most gasoline
brands include additives to keep engine and
fuel systems clean, they are not equally effec­
tive.
Aud i recommends using TOP TIER Detergent
Gasoline. For more information on TOP TIE R
Detergent Gasoline, please go to the officia l
website (www.toptiergas .com) .
Afte r an extended pe riod of using inadequate
fuels, built-up carbon deposits can rob your
engine of peak performance.
CD Note
- Damage or malfunction due to poor fuel
quality is not covered by the Audi New
Vehicle Limited Warranty.
- Do not add aftermarket fuel additive
products to your fuel tank.
Fuel tank
Fuel filler neck
The fuel filler neck is located on the r ight rear
side panel behind the fuel filler flap.
If the power locking system should fail, you
can sti ll open the flap manually - for detailed
instructions see
c:> page 211.
You can find the fue l tank capacity of your ve ­
hicle in

Fuel supply and filling your fuel tank 209
The label on the inside of the fuel fi lier f lap
te lls you the correct fue l for your vehicle. For
more information about fuel specifications,
see
c:> page 207.
Your vehicle fue l tank has an on -board refue l­
ling vapor recovery system. This feature helps
to prevent fuel vapors from escaping from the
tank and polluting the environment while you
refuel your vehicle. In order to fill the tank
proper ly while protecting the environment,
please follow this refueling procedure careful­
ly.
_&. WARNING
Under normal operating conditions, never
carry additional fuel containers in your car.
Gas canisters and other containers used to
transport fuel can be dangerous. Such con­
tainers, 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 al­
ways observe local and state laws regard­
ing the use, transportation and storage of
such fuel containers. Make certain the con­
tainer meets industry standards (ANSI/
ASTM F852 - 86).
CD Note
Never drive your veh icle until the fuel tank
i s completely empty. The irregu la r supply
of fue l can cause misfiring. Gasoline cou ld
enter the exhaust system and damage the
catalytic converter.

A WARNING
-Im proper refueling or handling of fuel can
cause fire, explosion and severe burns.
- Fuel is highly flammable and can cause
severe burns and other injuries.
- Failure to shut the engine off while refu­
eling and/or to insert the pump nozzle
fully into the fuel filler neck could cause
fuel to spray out of filler neck or to over­
flow. Fuel spray and overflowing fuel can cause a fire .
- Never use a cellular telephone while re­
fueling. The electromagnet ic rad iat ion
can cause sparks that can ignite fuel va­
pors and cause a fire.
- Never get back into your vehicle whi le re­
fue ling.
If in exceptional circumstances
you must get back in your vehi cle while
refueling, make ce rtain that you close
the door and touch metal to discharge
static electricity before touching the fill­
er nozzle again. Static electricity can
cause sparks that can ignite fuel vapors released during refueling.
- Never smoke or have an open flame any­
where in or near your vehicle when refu­
eling or filling a portable fuel conta iner.
- For your safety, we strongly recommend
that you do not travel with a portable
fuel conta iner in your vehicle . The con­
tainer, full or empty may leak and could
cause a fire, especially in a crash.
- If, u nder exceptional cir cumstances, you
must transport a portable fuel conta iner,
p lease observe the following:
- Never fill a portable fuel container
whi le 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 fue l conta iner
on the ground before filling.

~ co
rl I.O
"' rl
"' rl
-Always keep the f iller nozzle complete­
ly inside the portable conta iner before
and during filling.
- If filling a portable container made of
metal, the filler nozz le must always be
in contact with the container. Th is w ill
he lp prevent static electricity from dis­
charg ing and cause a fire .
- Never sp ill fuel inside the vehicle or
luggage compartment. Fue l vapors are
h ighly f lammable .
- Always observe local and state/provin­ cial laws regarding the use, storage
and tra nspo rta tion of fuel containers.
- Make certa in the fuel conta iner meets
industry standards (A NSI
I ASTM
F852-86).
(D Note
If any fuel has spilled onto the car, it
should be removed immediate ly to prevent
damage to the paint.
@ For the sake of the environment
As soon as the correctly operated nozzle
sw itches off automatically for the fi rs t
time, the tank is full. Do not try to add
more f ue l because fuel may spill out. In
add it ion , the expans io n s pace in the fuel
t ank will be fi lled -ca using the fue l to
overflow when it becomes warm and pol ­
lute the env iro nment.
@ Tips
- Runn ing yo ur engine while re fuelling
may ca use vapors to escape o r even
ca use fue l to spill out of the tank . This
would then shut off the fuel nozzle be­
fo re the tank is fu ll.
- Do not refuel your ve hicle w ith the igni ­
tion t urned on. The fuel gauge may oth­
erwise not ind icate the correct fue l level
after refuel ling.

Engine oil
· Engine oil specifications
The engine oil used must conform to exact
specifications.
The service interval disp lay in the instrument
cluster of your vehicle will inform you when it
is time for a n oil change . We recommend that
you have your oil changed by an authorized
Audi Se rv ice Adv isor.
If you have to top off the o il between o il
changes, use the Audi o il quality standard
specified in the tab le.
Audi oil quality standard
Gasoline
VW 502 00 or
engine vw 504 00

Using the proper engine oil is important for
the functionality and service life of the en­
g ine. Your engine was factory -filled with a
h igh-quality oil which can usually be used
t h roughout the entire year.
Your Limited New Vehicle Warranty does not cover damage or ma lf u nctions due to
fa ilure to follow recommended mainte­
nance and use requirements as set forth in
the Audi Owner's Manual and Warranty
&
Ma intenance booklet .
- Use only a high quality eng ine oil that ex­
pressly complies w ith the Audi o il quality
sta ndard specified for your veh icle's e n­
gine . U sing any other oil can cause seri­
ous eng ine dam age.
- Do not m ix any l ubrica nts o r othe r addi­
tives into the eng ine oi l. Doing so can
ca use eng ine damage.
I f you need to add oil and there is no ne
availab le tha t mee ts the Audi o il qua lity
s t andard your engine requires, yo u may
add a tota l of no more than 0 .5 quart/ liter
of a high -quality "synthetic"oil t hat meets
the following specifications.
- Vehicles with gaso line engine: ACEA A3
or API S M with a viscosity grade of
SAE 0W-30, SAE SW-30 or SA E SW-40.

Engine oil consumption
The engine in your vehicle depends on an ade ­
quate amount of oil to lubricate and cool all
of its moving parts.
In order to provide effective lubrication and
cooling of inte rnal engine components, all in-
~ ternal combustion eng ines consume a certai n ,....,
Checking and fillin g 215
amoun t of oil. Oil consumpt ion varies from
engine to engine and may change significantly
over the life of the engine . Typically, engines
with a spec ified break-in period (see
¢
page 193) consume more oil during the
break -in period than they consume after o il
consumption has stabilized .
U nder normal cond itions, the rate of oil con ­
sumption depends on the quality and viscos ity
of the oil, the RPM (revolutions per minute) at
which the engine is operated, the ambient
temperature and road conditions. Further fac­
tors are the amount of oil dilut ion from water
condensa tion or fue l resid ue an d the oxida­
t ion level of the o il. As any engine is subject to
wear as mi leage b uilds up, the oil consump ­
tion may increase over time until replacement
of worn components may become necessary.
With a ll these variab les coming into p lay, no
standard rate of oil consumption can be es ­
tablished or specified. There is no alternative
to regular and frequent check ing of the o il lev ­
el, see
Note .
If the yellow engine oil leve l warning symbo l
El in the instrument cl uster lights up, you
sho uld check the oil leve l as soon as possib le

216 Checking and filling
-If you have the impression your engine
consumes excessive amounts of oi l, we
recommend that you consult an author­
ized Audi dealer to have the cause of
your concern properly diagnosed. Keep in
mind that the accurate measurement of
oil consumption requires great care and
may take some time . An authorized Audi
dealer has instructions about how to
measure oil consumpt ion accurately.
