In order to fill the tank properly while protecting the environment,
please follow this refueling procedure carefully.
& 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 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 containers. Make certain the
container meets industry standards (ANSI/ASTM F852 -86).
0 Note
Never drive your vehicle until the fuel tank is completely empty . The
irregular supply of fuel can cause misfiring. Gasoline could enter the
exhaust system and damage the catalytic converter. •

& 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 neck 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
cause a fire.
• Never get back 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 electr icity before touching the filler nozzle again .
Static electricity can cause sparks that can ignite fuel vapors
released during refueling.

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 except ional circumstances, you must transport a
portable fuel container , please obser ve 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 causing a fire.
- Always place a portable fuel container on the ground before
filling.
Safety first
& WARNING (co ntinued )
-Alw ays 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 . Th is will help
prevent static electricity from discharging and cause a fire.
- Never spill fuel inside the veh icle or luggage compartment .
Fuel vapors are highly flammable.
- Always observe local and state/provincial laws regarding the
use, storage and transportation of fuel containers.
- Make certain the fuel containe r meets industry standards

Changing the engine oil
The engine oil and oil filter must be changed according to the mileage
(kilometers) and time intervals specified in your vehicle's Warranty
&
Maintenance booklet. Do not exceed these intervals -harmful
deposits from old engine oil can reduce engine performance and can
lead to expensive engine repairs.
Changing the oil at the recommended intervals is so very important
because the lubricating properties of oil decrease gradually during
normal vehicle use. If you are not sure when you have your oil
changed, ask your authorized Audi Service Advisor .
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 temper­
atures 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 oil at the recommended intervals
using only engine oil that complies with Audi oil standard
VW
502 00 . Your Limited New Vehicle Warranty does not cover
damage or malfunctions due to failure to follow recommended main­
tenance 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. •
Safety first
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 internal
engine components, all internal combustion engines consume a
certain amount of oil. Oil consumption varies from engine to engine
and may change significantly over the life of the engine. Typically,
engines with a specified break-in period (see~
page 250) 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 consumption
may increase over time until replacement of worn components may
become necessary.
With all these variables coming into play, no standard rate of oil
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
~ page 284. Top off the oil at your earliest convenience~ page 284.
& WARNING
Before you check anything in the engine compartment, always
read and heed all WARNINGS~
& in "Working in the engine
compartment" on page
280.

Driv ing with an insufficient o il level is likely to cause severe damage
to the engine .
[ i J Tips
• The oil pressure wa rning display 9:!::r. is not an ind icator of the oil
level. Do not rely on it. Instead, check the oil level
in your engine at
r egula r inte rvals , prefe rably ea ch time you refuel , and always
before going on a long trip.
• If you have the impression your engine consumes excessive
amounts of o il, we recommend th at yo u consult an autho riz ed Aud i
dealer to have the cause of your concern properly diagnosed . Keep in
m ind that the accurate measu rement of oil consumption re quires
great care and may take some t ime. An authorized Audi dealer has
instructions about how to meas ure oil consumption accu rately .•
Checking the engine oil level

The oil leve l needs to be c hec ked at regular intervals. The bes t times
to do this are whe neve r you refuel and p rior to long tr ips.
Depending on the way the vehicle is driven and the operating condi­
ti ons, oi l cons ump tion can be u p to 1/2 q uart per 600 m iles (0.5 l iter
per 1,000 km). Consumpt ion may be higher with in the first 3,000

Tires and vehicle load limits
There are limits to the amo unt of load or weig ht that any vehicle and
any t ire ca n carry. A veh icle th at is overlo ade d w ill n ot handle well and
is more difficult to stop . Overload ing can not on ly lead to loss of
vehicle co ntro l, bu t can also d amage important pa rts of the vehi cle
and can lead to sudden t ire failure, including a b lowo ut and sudden
deflation that can ca use the vehicle to c rash.
Yo ur safety and t hat of your passengers also depends o n mak ing s ure
that load limits are not e xceeded. Vehicle load incl udes eve rybody
and everyth ing in and on the ve hicle. These load limits are tech nically
refer red to as the veh icle's
Gross Vehicle We ight Rating ("GVWR").
T he "GVWR" includes t he weight of the basic vehi cle, all factory
installed accessories, a fu ll tank of fue l, o il, coo la nt and other fluids
plus maxim um load . The maxim um load includes the number of
passenge rs that the vehi cle is intended to car ry ("seating capacity ")
w ith an ass umed we ight of 150 lbs (68 kg) for each pa ssenger at a
designat ed seating position and the tota l w eight of any l uggage in
the vehicle. If you tow a trai le r, the weight o f the t railer hitch and the tongue weight of the
loaded tra ile r must be included as part of the
