Fuel supply and filling your fuel tank
Your vehicle fuel tank has an on-board refuelling vapor recovery
sys te m. Th is f eat ure he lp s to p re vent f uel vapors from es ca pin g
from the tan k and polluting the environment while you refue l your
vehic le . In ord er to fill t he tank pr ope rly while protec tin g the e nvi ­
ronm ent, pl eas e follow this refu eling procedur e carefu lly.
& WARNING
Under normal operat ing conditions , never carry additional fuel
containers in your car. Gas canisters and other containers used to
tran sport fuel 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 , trans­
portation and storage of such fuel container s. Make certain the
container meets industry standards (ANSI/ASTM F852 -86).

& WARNING
Improper 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 refueling and /or to insert
the pump nozzle fully into the fuel filler ne ck could cause fuel to
spray out of filler neck or to overflow. Fuel spray and overflowing
fuel can cause a fire .
• Never use a cellular telephone while refueling . The electromag ­
netic radiation can cause sparks that can ignite fuel vapors and
c ause a fire .
• Never get ba ck into your vehicle while refueling .
If in excep­
tional circumstances you must get back in your vehicle while refu ­
eling , make certain that you close the door and touch metal to
discharge static electricity before touching the filler nozzle again.
& WARNING (continued )
Static electricity can cause sparks that can ignite fuel vapors
released during refueling .
• Never smoke or have an open flame anywhere in or near your
vehicle when refueling or filling a portable fuel 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 cause a fire , especially in a crash .
• If, under e xceptional 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 compartment , or on
the trunk). Static electricity can build up while filling and can ignite fuel vapors cau sing a fire.
- Always place a portable fuel container on the ground before
filling.
- Always keep the filler nozzle completely 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 spill fuel inside the vehicle or luggage compartment .
Fuel vapors are h ighly flammable.
- Alway s observe local and state /provincial laws regarding the
use , storage and transportation of fuel containers.
- Make certain the fuel container meets industry standards
(ANSI / ASTM F852-86I.

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.
W For the sak e of the environm ent
As soon as the correctly ope rated nozzle swi tches off automatical ly
for the first time, the tank is full. Do not try to add more fuel because
fue l may spill out . In addition, the expansion space in the fuel tank
wi ll be filled -causing the fuel to overflow when it becomes warm
and pollute the environment.
[ i J Tip s
• Running your engine while refuelling may cause vapors to
escape or even fuel to spill out of the tank . Th is would then shut off
the fue l nozzle before the tank is full.
• Do not refuel your veh ic le with the ignit ion switched on. The fue l
gauge may otherwise not indicate the correct fuel level after
refuel ling .•
Unlocking the fuel filler flap by hand
You can open the fuel filler flap by hand
if the power

Closing the engine hood
- Pull the hood down until the pressure from the strut is
reduced.
- Let the hood
drop down and latch in place. Do not try to
push it shut;
it may fail to engage~& .
& WARNING
A hood that is not completely latched could fly up and block your
view while driving.
• When you close the engine hood, check it to make sure the
safety catch has properly engaged. The hood should be flush with
the surrounding vehicle body parts.
• If you notice while driving that the hood is not secured prop­
erly, stop at once and close it. •
Working in the engine compartment
Be especially careful whenever you work in the engine
compartment!
Whenever you must perform any work in the engine compartment,
for example checking and filling different fluids, there is a risk of injury, burns and accidents. To prevent personal injury always
observe the following WARNINGS. The engine compartment of any
vehicle is a hazardous area!
=> &
& WARNING
To help avoid injury, before you check anything under the hood :
• Turn off the engine.
• Remove the ignition key.
• Set the parking brake fully .
& WARNING (continued)
• Move selector lever of automatic transmission to "P" {Park);
put manual transmission in Neutral.
• Always let the engine cool down. Hot components will burn
skin on contact.
• To reduce the risk of being burned, never open the hood if you
see or hear steam or coolant escaping from the engine compart­
ment. Wait until no steam or coolant can be seen or heard before
carefully opening the hood .
• Keep children away from the engine compartment.
• Never spill fluids on hot engine components. They can cause a
fire.
• Never touch the radiator fan. The auxiliary electric fan is
temperature controlled and can switch on suddenly.
• Never open the coolant reservoir cap when the engine is still
warm. The coolant system is pressurized and hot coolant could
spray out!
• Protect your face, hands and arm from steam or hot engine
coolant by placing a thick rag over the cap when you open the
coolant reservoir.
• If work on the fuel system or the electrical system is necessary:
- Always disconnect the battery .
- Never smoke or work near heaters or open flames. Fluids in
the engine compartment could start a fire.
- Keep an approved fire extinguisher immediately 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: .,_

Under some circumstances the engine oil should even be changed
more frequently. Change oil more often if you drive mostly short
distances, operate the vehicle in dusty areas or mostly under stop ­
and -go traffic conditions, or when you use your vehicle where
temperatures stay below freezing point for long periods .
Detergent additives in the oil will make fresh oil look dark after the
engine has been running for a short time. This is normal and is not
a reason to change the oil more often than recommended .
Damage or malfunctions due to lack of maintenance
It is essential that you change your oi l at the recommended intervals
using only engine oil that complies with Audi oil standard
VW 502 00 (vehicles with gasoline engine) or VW 507 00 (vehicles
with diesel engine). Your Limited New Vehicle Warranty does not
cover damage or malfunctions due to failure to follow recom­
mended maintenance and use requirements as set forth in the Audi
Owner's Manual and Warranty
& Maintenance booklet. Your dealer
will have to deny warranty coverage unless you present to the dealer proof in the form of Service or Repair Orders that all scheduled
maintenance was performed in a timely manner .•
Engine oil consumption
The engine in your vehicle depends on an adequate
amount of oil to lubricate and cool all of its moving parts.
In order to provide effective lubrication and cooling of interna l
engine components, all internal combustion engines consume a
certain amount of oil. Oil consumption varies from engine to engine
and may change significant ly over the life of the engine. Typically,
engines with a specified break -in period (see=>
page 195) consume
more oil during the break-in period than they consume after oil
consumption has stabilized.
Under normal conditions, the rate of oil consumption depends on
the quality and viscosity of the oil, the RPM (revolutions per minute)
at which the engine is operated, the ambient temperature and road
conditions. Further factors are the amount of oil dilution from water condensation or fuel residue and the oxidation level of the oil. As
any
engine is subject to wear as mileage builds up, the oil consump­
tion may increase over time until replacement of worn components
may become necessary .
With all these variables coming into play, no standard rate of oi l
consumption can be established or specified. There is no alternative
to regular and frequent checking of the oil level, see
Note.
If the yellow engine oil level warning symbol in the instrument
cluster lights up, you should check the oil level as soon as
possible
with the oil dipstick=> page 229. Top off the oi l at your
earliest convenience =>
page 230.
& WARNING
Before you check anything in the engine compartment, always
read and heed all WARNINGS
=> &. in "Work ing in the engine
compartment" on
page 224.
0 Note
Driving with an insufficient oil level is likely to cause severe damage
to the engine.
[ i ] Tips
• The oil pressure warning display~ is not an indicator of the oil
level. Do not rely on it. Instead, check the oil level in your engine at
regular intervals , preferably each time you refuel, and always before
going on a long trip.
• If you have the impression your engine consumes excessive
amounts of oil, we recommend that you consu lt your authorized
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. Your authorized Audi
dealer has instructions about how to measure oil consumption
accurately. •

Determining oil level
- Park your vehicle so that it is horizontally level.
- While at operating state temperature, briefly let the
engine run at idle and then shut it off.
- Wait approx. two minutes. - Pull out the
oil dipstick. Wipe off the oil dipstick with a
clean cloth, and slide it back in as far as it will go.
- Pull it back out and read off the oil level=> fig. 166 or
=> fig. 167. Top off the engine oil, if applicable
=> page 230.
Oil level within range @
- Do not add oil.

The oil level needs to be checked at regular intervals . The best times
to do this are whenever you refuel and prior to long trips.
Depending on the way the vehicle is driven and the operating condi­
tion s, oil consumption can be up to 1 quart per 1.200 miles (1 liter
per 2.000 km). Consumption may be higher within the first 3.000
miles (5.000 km) .•

is a tire information system developed by the United States Nationa l
Highway Traffic Safety Administration (N HTSA) that is designed to
help buyers make re lative comparisons among tires. The UTQG is
not a safety rating and not a guarantee that a tire will last for a
prescribed number of miles or perform in a certain way. It simply
gives tire buyers additiona l information to combine with other
considerations, such as price, brand loya lty and dealer recommen- dations
. Under UTQG, tires are graded by the tire manufacturers in
three areas : treadwea r, trac tion and temperature resistance. The

Cold tire inflation pressure
Tire
pressure affects the overall handling, performance and safety of a vehicle.
Fig. 173 Tire pressure
label: located either on
driver's side B-pillar or
inside the fuel filler flap
Tire pressure generally refers to the amount of air in a tir e that it
needs it to do its job and safely carry the combined load of the entire
vehicle and its contents. Tire pressure is measured in kilopascals
(kPa), the international measuring unit and in pounds per square
inch (PSI). Tire pressure is based in part on the vehicle's design and
load limit -the greatest amount of weight that the vehicle can carry
safely and the tire size. The proper tire pressure is frequently
referred to as the "recommended cold tire inflation pressure." Air in
the tires expands when the tire heats up because of internal friction
when it flexes in use. The tire pressure is higher when the tire has
warmed up than when it is "cold ." It is the inflation pressure in a
"cold" tire that counts. Therefore, you should never let air out of a
warm tire to match "cold tire inflation pressure" recommendations .
The tires would then be underinflated and could fail suddenly.

Maintaining proper tire pressure is one of the most important
th ings you can do to help avoid sudden tire failure . Underinflated
tires are a major cause of sudden tire failure. Keeping tires at the
right pressure is also important for safe and responsive vehicle
handling, traction, braking and load carrying .
Tire pressures are
particularly important when the vehicle is being driven at higher
speeds, and then especially when heavily loaded even within the
permissible load -carrying capacities approved for your vehicle.
The recommended tire pressures for your Audi depend on the kind
of tires on your vehicle and the number of passengers and/or
amount of luggage you will be transporting.
On USA vehicles, the tire pressure label is located on driver's side B ­
pillar. On Canada vehicles, the tire pressure label is located either on
the driver's side B -pillar or inside the fuel filler flap. The tire pressure

Because technica l changes may be made to vehicle equipment
during the mode l year, always compare the tire size designat ion on
the tire pressure la bel on y our vehicle with the tires on your vehicle.
Make sure tha t the t ire size information on the veh icle labe l is the
same as the size of the tires on the vehicle. This is especially impor ­
t ant if the vehicle belongs to someone e lse or you boug ht the
vehic le with different rims/tires or you bought the vehicle as a previ ­
ously owned vehicle.
Remember, your safety and that of your passengers a lso depends
on making su re tha t load limits a re not exceeded . Vehicle load
inc ludes everybody and everything in and on the vehicle. These load
limits are technically referred to as the vehicle's Gross Vehicle
Weight Rating ("GVWR"). The Gross Axle Weight Rating ("GAWR") is
the maximum load that can be applied at each of the vehicle's two

Rating are listed on the safety comp liance sticker labe l located
e it he r on the d river's side B-pillar o r on the i nside of the fuel f iller

& WARNING
Overloading a vehi cle can cause los s of vehicle control , a crash or
other accident, serious per sonal injury, and even death .
• Carrying more weight th an your vehicle was de signed to carry
will prevent the vehicle from handling properly and increase the
risk of a loss of vehicle control.
• The brakes on a vehicle that has been overloaded may not be
able to stop the vehicle within a safe distance .
• Tires on a vehicle that has been overloaded c an fail suddenly
cau sing loss of control and a crash .
• Alway s make sur e that the total load being tran sported -
including the weight of a trailer hitch and the tongue weight of a
loaded trailer -does not make the vehicle heavier than the
vehicle 's Gross Vehicle Weight Rating . _.,
