Refuelling procedure
.,. Insert the fuel nozzle from the gasoline
pump into the fuel filler neck as far as it wi ll
go .
.,. Select a medium refuelling rate so that the
nozz le switches off automatically when the
tank is full.
Putting the fuel cap back on
.,. After filling your tank, twist the fuel filler
cap clockwise as far as it wi ll go.
.,. Close the fue l filler flap.
T o avoid fuel spilling or evaporating from the
fuel tank always close fuel filler cap properly
and completely . An improperly closed fuel fill­
er cap may also cause the MIL lamp¢
page 30
to come on.
A WARNING
Improper refue ling or handling of fuel can
cause fire, explosion and severe burns.
- Fuel is highly flammable and can cause
severe burns and other injur ies .
- Failure to shut the engine off while refu­
eling and/or to insert the pump nozzle
fully into the fuel filler neck could cause
fue l 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
fue ling. The electromagnet ic rad iation
can cause spa rks that can ignite fuel va­
pors and cause a fire.
- Never get back into yo ur vehicle while re­
fueling.
If in exceptional circumstances
you must get back in your vehicle while
refueling, make certain that you close
the door and touch metal to discharge stat ic 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 f lame any­
where in or near your veh icle when refu-
eling or filling a portab le fuel conta iner. .,.

222 Fuel su ppl y and fillin g yo ur fu el t an k
- For your safety , we strongly recommend
that you do not travel with a portable
fuel container in your vehicle. The con­
tainer, full or empty may leak and could cause a fire, especially in a crash.
- If, under exceptional circumstances, you
must transport a portable fuel container,
please observe the following:
- Never fill a portab le fuel container
while 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 n ite fuel vapors causing a fire .
- Always place a portable fuel container
on the ground before filling.
- Always keep the fi ller nozzle complete­
ly 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 dis­
charging and cause a fire .
- Never sp ill fuel inside the vehicle or
luggage compartment. Fuel vapors are
h ighly flammable.
- Always observe local and state/provin­
cial laws regarding the use, storage
and transpo rtation of fuel conta iners.
- Make certa in the fuel container meets
industry standards (ANSI/ ASTM
F8S2-86).
@ Note
If any fuel has spilled onto the car, it
should be removed immed iately 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 first
time, the tank is full . Do not try to add
mo re fuel because fuel may spill out. In
add it ion, the expans ion space in the fuel
tank will be f illed -causing the fue l to overflow when it becomes warm and pol­
lute the environment .
(D Tips
-Running your engine whi le refue lling
may cause vapors to escape or even
cause fuel to spi ll out of the tank. This
would then shut off the fue l nozzle be­
fore the tank is full.
- Do not refuel your vehicle with the igni­
tion switched on. The fuel gauge may
otherwise not ind icate the correct fuel
level after refuelling .
- Diesel vehicles* are equipped with a die­ sel misfueling protector. It allows the
vehicle to be fueled only with a diesel
fuel pump nozzle. A worn or damaged nozzle or a nozzle that is too small may
not be ab le to open the diesel misfueling
protector. If this is the case, try turning
the nozzle before insert ing it in the f uel
filler neck, use a different fuel pump or
see your authorized Audi dea ler or au­
thorized repair facility for assistance.
- The fuel fi ller f lap of your vehicle is not
locked when you lock the vehicle from
the inside.

Selective catalytic
reduction
General information
App lies to vehicles: wi th diesel eng ine
On vehicles with se lective cata lytic reduc tion,
an urea solution (Ad Blue) is injected into the
exha ust system before a nitrogen oxide cata­
lytic converter to reduce n itrogen emissions.
The Ad Blue is s tored in a separate tank in the
vehicle. The Ad Blue usage accounts for ap­
proximately 0.5% to 1.2% of the diesel fue l
that is used.
You must refill the Ad Blue or have it refi lled
by your authorized Audi dea ler or q ua lified
workshop as soon as the Ad Blue refill mes­
sage appears in the instrument cluster
c> page225.
A WARNING

current list of oils (manufacturers, brand
names etc.) that conform to Audi oil standard
VW 502 00 (vehicles with gasoline engine) or
VW 507 00 (vehicles with diesel engine).
C hanging the engine oil
The engine oil and oil filter must be changed
according to the mileage (kilomete rs) and
time intervals specified in your vehicle's War­
ranty
& 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 inter­
vals is so very important because the lubricat­
ing properties of oil decrease gradually during
normal vehicle use. If you are not sure when
you have your oil changed, ask your author­
ized 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 con­
ditions, or when you use your vehicle where
temperatures stay below freezing point for long periods.
Detergent addit ives in the oil will make fresh
oil look dark after the eng ine has been run­
ning 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 (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 fol­
low recommended maintenance and use re­
quirements as set forth in the Audi Owner's
Manual and Warranty
& Maintenance booklet.
Your dealer will have to deny warranty cover­
age unless you present to the dealer proof in
Checking and filling 231
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 ade­
quate 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 in­
ternal 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 204) consume more oil during the
break-in period than they consume after oil
consumption has stabilized.
Under normal conditions, the rate of oil con­
sumption 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 fac­
tors are the amount of oil dilution from water
condensation or fuel residue and the oxida­
tion 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 oil consumption can be es­
tablished or specified. There is no alternative
to regular and frequent checking of the oil lev­
el, see
Note .
If the yellow engine oil level warning symbol
in the instrument cluster
II! lights up, you
should check the oil level as soon as possible
¢
page 232. Top off the oil at your earliest
convenience

your engine at regular intervals, pref ­
erably each t ime you refuel, and always
before going on a long trip .
-If you have the impression your engine
consumes excessive amo unts of oi l, we
recommend that yo u consult your Audi
dealer to have the ca use of you r co nce rn
prope rly diagnosed. Keep in mind that
t h e accurate measure men t of oil con­

-Never mount used tires on yo ur vehicle if
you are not sure of their "previous histo­
ry." Old used tires may have been dam­
aged even though the damage cannot be
seen that can lead to sudden t ire failure
and loss of vehicle control.
- If you notice unusual vibration or if the
vehicle pulls to one side when driving, al­
ways stop as soon as it is safe to do so
and check the wheels and tires for dam­
age.

Glossary of tire and loading terminology
Accessory weight
means t he comb ined we ight (in excess of
those sta ndard items which may be rep laced)
of au toma tic tra nsmission, power steer ing,
power brakes, power windows, power seats,
radio, and heater, to the extent that th ese
items are availab le as factory -installed equip­

dicate a low sidewall for improved steering re­
sponse and better overall handling on dry pavement .
Bead
means the part of the ti re that is made of
steel wires, wrapped or reinforced by ply cords
and that is shaped to fit the rim.
Bead separation
means a b reakdown of the bond between
components in the bead.
Cord
means the strands forming the plies in the
tire . typ
ica l in those seasons . Audi recommends
using winter tires during the winter
months . Low temperatures signif icant ly
decrease the e lasticity of summer tires,
which affects tract ion and brak ing ability.
If summer tires are used in very co ld tem­
peratures, cracks ca n form on the tread
bars, res ulting in permanent tire damage
that can cause loud driving no ise and un­
balan ced t ires. Audi is not responsible for
th is type of damage .
Cold tire inflation pressure
means the tire p ressu re recommended by t he
vehicle manufacturer fo r a tire of a des igna ted
s iz e that has not bee n driven for more than a
coup le of miles (k ilometers) at low speeds in
t h e three hour period before the tire pressure
is measured or adjusted.
Curb weight
mea ns the we ight of a motor ve hicl e w ith
standard equipment including the max imum
capacity of fuel, oil, and coolant, air condi ­
tioning and additional weight of optiona l
equipment.
Extra load tire
me ans a t ire design to operate at higher loads
and at h igher inflation pressures than the cor­
responding standard tire . Extra load tires may
be identified as "XL", "x l" , "EXTRA LOAD", or
"RF" on the sidewall.
Gross A xle Weight Rating ("GAWR ")
means the lo ad -c a rry ing c apac ity of a s ingle
axle system , measured a t the tire-ground in­

-The use of incorrect tire pressure values
can lead to accidents or other damage.
Therefore it is essential that the driver observe the specified tire pressure values
for the tires and the correct pressu res for
the funct ion of the tire pressure mon itor­
ing system*.
- Always inflate t ires to the recommended
and correct tire pressure before driving
off.
- Driv ing with under inflated tires bend
more, letting them get too hot resu lting
in tread separation, sudden t ire fa il u re
and loss o f control.
- Excessive speed and/ove rloading can
cause heat bui ld-up, sudden tire fail ure
and loss o f control.
- If the t ire pressure is too low or too high,
the tires w ill wear prematurely and the
vehicle will not hand le we ll.
- If the t ire is no t flat and you do not have
to change a wheel immediate ly, drive at
reduced speed to the nearest service sta­
tio n to check the tire pressure and add
air as required.
(D Note
Dr iving without va lve stem caps ca n cause
damage to the tire va lves. To prevent this,
always make sure that factory installed
valve stem caps on all wheels are secure ly
mounted on the va lve.
@ For the sake of the environment
Underinflated tires will a lso increase the
fue l consumption .
Tires and vehicle load limits
There are limits to the amount of load or
weight that any veh icle and any t ire can carry .
A vehicle that is overloaded w ill not handle
well and is more difficult to stop . Overload ing
can not on ly lead to loss of vehicle con trol,
b ut can a lso damage important par ts of the
vehicle and can lead to sudden tire failure, in­
cluding a blowout and sudden deflation that
can cause the vehicle to crash.
Tire s an d wheel s 251
Your safety and that of your passengers also
depends on making sure that load limits are
not exceeded. Vehicle load includes everybody
and everything in and on the veh icle. These
load lim its are technically referred to as the
vehicle's
Gro ss Ve hicle Wei ght R ating
("GVWR") .
The "GVWR" includes the weight of the basic
vehicle, all factory installed accessories, a full
tank of fuel, o il, coolant and other fluids plus
maximum load. The max imum load includes
the number of passengers that the vehicle is
in tended to carry ("seat ing capac ity") with an
assumed we ight of 150 lbs (68 kg) for each
passenger at a designated seating posit ion
and the total weight of any luggage in the ve­ hicle . If you tow a trai ler, the weight of the
trailer hitch and the tongue weight of the
loaded tra iler must be included as part of the
vehicle load.
The
Gr oss Ax le We ight R ating ("GAWR") is
the maximum load that can be applied at each
of the vehicle's two axles.
The Gross Vehicle Weight Rating and the
Gross Axle Weight Rating are listed on the
safety comp liance sticker label located on the
driver's side B-pillar. Your Audi has 4 seat ing
pos itions, 2 in the front and 2 in the rear for
total seating capacity of 4 . In some vehicles
there are 5 seating pos it ions, 2 in the front
and 3 in the rear for tota l seating capacity of
5. Each seat ing position has a safety belt
~ page 140, Safety belts .
The fact that there is a n upper limit to you r
vehicle's Gross Vehicle Weight Rating means
that the total weig ht of whatever is being car­
ried in the vehicle ( includ ing the weight of a
trailer hitch and the tongue weight of the
loaded trai ler) is limited . The more passen­
gers in the vehicle or passengers who are
heavier than the standard we ights assumed
mean that less we ight can be carried as lug­
gage .
The tire pressure label on your Audi also lists
the maximum combined weight of a ll of the
occupants and luggage or other cargo that ..,.
