~ Unscrew fuel cap counter-clockwise and
hang i t on the fuel filler flap
~ fig . 170.
Refuelling procedure
~ Insert the fuel no zzle from the gasoline
pump into the fuel filler nec k as far as it will
go .
~ Select a medium refuelling rate so that the
nozzle switches off automatical ly when the
tank is full.
Putting the fuel cap back on
~ After filling your tank, tw ist the fuel cap
clockwise as far as it will go .
~ Close the fuel filler flap. T
o avoid fuel spill ing or evaporating from the
fuel tank always close fuel cap properly and
completely .
A 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 refu­
eling and/or to insert the pump no zzle
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 vehicle while
ref ueling, 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 veh icle 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 f uel 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.

-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.
- The fuel filler flap of your vehicle is not locked when you lock the vehicle from
the i nside.

-To reduce the r isk of being burned, never
open the hood if you see or hear steam
or coolant escaping from the engine
compartment . Wait until no steam or
coolant can be seen or heard before ca re­
fully opening the hood .
- Keep children away from the engine com ­
partment.
- Never spill flu ids on hot engine compo­
nents. They can cause a fire .
- Never touch the radiator fan. The aux ili­
ary e lectr ic fan is temperature controlled
and can switch on suddenly .
- Never open the coolant reservoir cap
when the eng ine is still warm . The cool­
ant system is pressur ized and hot coo l­
ant could spray out.
- Protect your face, hands and arm from
steam or hot eng ine coolant by placing a
thic k rag over the cap when you open the
coolant reservoir.
- Do not remove the engine cover under
any c ircumstances. Th is increases the
risk of bu rns.
- If wo rk on the fuel system or the electri­
cal sys tem is ne cessary:
- Always disconnect the battery.
- Never smoke or work near heaters or
open flames . Fluids in the engine com­
partment co uld start a fire.
- Keep an approved fire extinguisher im­
mediately ava ilable.
- To avoid electrical s hock and persona l in­
jury 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 repa ir
with the engine running:
- Fir st, fully apply the parking brake,
move se lector lever of a utomatic trans­
mission to "P" (Park).

temperatures stay below freezing point for
long periods.
Detergent addit ives in the o il w il l make fresh
oil look dark after the eng ine has been run­
ning for a short time . This is norma l and is not
a reason to change the oi l more often than
recommended.
D am age or m alfunc tions du e to lack of
m ainten ance
It
is essential that you change your oil at the
recommended in tervals using only engine o il
that complies with Audi oi l standard
VW 502 00. Your Limited New Vehicle War­
ranty does not cover damage or malfunctions
due to fail ure to fo llow recommended mainte­
nance and use requ irements as set forth in
the Audi Owner's Manual and Warranty
&
Maintenance book let . Your dealer will have to
deny warranty coverage unless you present to
the dea ler proof in the form of Service or Re­
pa ir Orders that all scheduled ma intenance
was performed in a t imely manner.
Eng ine 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
cool ing of internal engine components, a ll in­
ternal combustion eng ines consume a certa in
amount of oil. O il consumption varies from
engine to engine and may change significantly
over the life of the engine. Typica lly, engines
with a specif ied break-in period (see
¢
page 187) consume more oil during the
break-in period than they consume after oil
consumption has stabilized.
Under norma l 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 condit ions . Further fac­
tors are the amount of oil d ilution from water
condensat ion or fuel residue and the ox ida­
tion level of the oi l. As any engine is subject to wear as mi
leage builds 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 play, no
standard rate of oil consumption can be es­
tablished or specified. There is no alternative
to regu lar and frequent check ing of the o il lev ­
el, see
Note .
If
the yellow engine oil leve l warning symbo l
I! in the instrument cluster lights up, you
shou ld check the oil leve l as soon as possib le

A WARNING '"---
Before you check anythi ng in the engine
compartment, always read and heed all
WARNINGS¢

compartment on page 212.
(D Note
Driving w ith an insufficient o il level is like­
ly to cause severe damage to the engine .
(D Tips
-The oil pressu re warn ing display . is
not an indic ator of the oil l evel. Do not

erably ea ch time you r efu el, and alwa ys
before go ing on a long trip .
-If you have t he impression yo ur engine
consumes excessive amoun ts of o il, we
recommend that you consu lt an author­
ized Aud i dea ler to have the cause of
your concern properly diagnosed. Keep in m ind that the accurate measu rement of
oil consumption requ ires great care and
may take some time. An authorized Aud i
dealer has instructions about how to
measu re oil consumption accurately.

228 Tire s and wheel s
-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.

Please note that summer and winter tires
are designed for the cond itions that are
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
ment (whether installed or not) .
Aspect ratio
means t he ratio of the he ight to the w idth of
the tire in percent . Numbers of 55 or lower in ­
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

- Always inflate tires to the recommended
and correct tire pressure before driving
off.
- Driving with under inflated tires bend
more, letting them get too hot resu lting
in tread separation, sudden t ire failure
and loss of control.
- Excessive speed and/overloading can
cause heat build-up, sudden tire fail ure
and loss of control.
- If the t ire pressure is too low or too high,
the tires w ill wea r prematurely and the
vehicle will not hand le we ll.
- If the t i re is not flat and you do not have
to change a w heel immed iate ly, dr ive at
reduced speed to the nearest serv ice sta­
t ion to check the tire pressure and add
air as requi red.

Tires and vehicle load limits
There are l imits to the amo un t of load or
weight that any vehicle and any tire can carry .
A veh icle that is overloaded w ill not handle
w ell and is more difficult to stop. Overload ing
can not only lead to loss of vehicle contro l,
but c an a lso damage import ant parts of the
ve hicle and can lead to sudden tire failure, in­
cluding a blowout and sudden deflation that
can cause the ve hicle to crash .
Your safety and that of your passengers a lso
depends on making sure that load limits are n ot exceeded. Vehicle load includes everybody
and everyth ing in and on the vehicle . Th ese
Tire s an d wheel s 235
load lim its are technically referred to as the
vehicle's
Gross Vehicle Weight Rating
("GVWR").
T he "GVWR" incl udes the weight of the basic
vehicle, a ll factory installed accessories, a f ull
tan k of fuel, oi l, coo lant and other fluids plus
max imum load. The max imum load incl udes
the n umber of passengers t hat the vehicle is
intended to carry ("seat ing capac ity") with an
ass umed we ight of 150 lbs . (68 kg) for eac h
passenger at a designated seating posi tion
and the tota l weight of a ny luggage i n the ve­
hicle. If you tow a tra ile r, the we igh t of the
tra iler hi tch and the tongue we igh t of t he
loaded tra iler mus t be included as part of the
vehicle load .
T he
Gro ss Axle Weight Rating (" G AWR ") is
the max imum load th at can be appl ied a t each
of the veh icle's two axles .
T he Gross Vehicle Weight Rat ing and t he
G ross Ax le Weig ht Ra ting are listed on the

The speed rating letter code (c::> page 230) is
on the side wall of the tire
c::> page 238.
A WARNING
Winter tires have maximum speed limits
that may be lower than your vehicle's max­
imum speed . Always know the maximum
speed before driving off. Never drive faster
than the speed permitted for your specific
winter tires . This will cause damage to the
tires leading to an accident and serious
personal injury to you and your passen­
gers.
A WARNING
Driving faster than the maximum speed
for which the winter tires on your vehicle
were designed can cause tire failure in­ cluding a blowout and sudden deflation,
loss of control, crashes and serious per­
sonal injuries . Have worn or damaged tires
replaced immediately.
- Winter tires have maximum speed rating
that may be lower than your vehicle's
maximum speed .
- Never drive faster than the speed for
which the winter or other tires installed
on your vehicle are rated .
A WARNING
Always adjust your driving to the road and
traffic conditions. Never let the good ac­
celeration of the winter tires and all wheel
drive tempt you into taking extra risks . Al­
ways remember :
- When braking, an all wheel drive vehicle
handles in the same way as a front drive
vehicle.
- Drive carefully and reduce your speed on
icy and slippery roads, even winter tires
cannot help under black ice conditions.
@l For the sake of the environment
Use summer tires when weather condi­
tions permit. They are quieter, do not wear
as quickly and reduce fuel consumption.
Tires and wheels 243
Snow chains
Snow chains may be fitted only to the front
wheels , and only to certain tire sizes. Ask your
authorized Audi dealer on which tire sizes
snow chains can be used.
The snow chains must have low-profile links
and must not be thicker than 0.53 inch
(13.S mm) , including the lock.
Remove wheel center covers and trim discs
before putting snow chains on your vehicle
c::> 0 . For safety reasons cover caps must then
be fitted over the wheel bolts. These are avail­
able from authorized Audi dealers.
A WARNING
~ Using the wrong snow chains for your vehi­
cle or installing them incorrectly can in­
crease the risk of loss of control leading to
serious personal injury.
- Snow chains are available in different sizes . Always make sure to follow the in­
structions provided by the snow chain
manufacturer.
- When driving with snow chains never
drive faster than the speed permitted for
your specific snow chains .
- Always observe local regulations.
(D Note
- Remove snow chains before driving on
roads not covered with snow to avoid
damaging tires and wearing the snow
chains down unnecessarily.
- Snow chains, which come into direct con­
tact with the wheel rim, can scratch or
damage it. Therefore, make sure that the
snow chains are suitably covered. Check
the position of the snow chains after
driving a few yards and correct if neces­
sary. Follow the instructions from the
snow chain manufacturer when doing so.
(D Tips
Where snow chains are mandatory on cer­
tain roads, this normally also applies to
vehicles with all wheel drive .
•
•

-Drive carefully on roads with potholes, deep
gullies or ridges. The impact from driving
thro ugh or over such obstacles can damage
your tires. Impact with a curb may also cause damage to your tires.
- After any impact, immediately inspect your
tires or have them inspected by the nearest
authorized Aud i dealer. Replace a damaged
t ire as soon as possible .
- Inspect your t ires every 2,000 miles (3,000
km) for damage and wear . Damage is not al­
ways easy to see . Damage can lead to loss of
air and underinflation, wh ich could eventu­
ally cause ti re fail ure. If you be lieve that a
t ire may have been damaged , replace the
t ir e as soon as possible.
- These tires may wea r more q uick ly than oth­
ers.
- Please also remember that, wh ile these t ires
deliver respons ive handling, they may ride
less comfortably and make mo re noise than
othe r choices .
Reduced performance in winter /cold
season condit ions
All t ires are des igned for certa in pu rposes.
The low aspect ratio, ultra high pe rformance
tires originally installed o n your vehicle are in­
tended for max imum dry and wet road per­
formance and handling . They are not suitable
for cold, snowy or icy weather condit ions. If
you dr ive under those circumstances, you
should equip your veh icle with all-season or
winter t ires, which offer better traction under
those cond itions . We suggest you use the re c­
ommended snow or all-season tires specified
for your ve hicl e, or their equ ivalent .

Tire pressure
monitoring system
U) General notes
Ap plies to vehicles: with tire pressure monitoring system
Each t ire , includ ing the spare (if provided),
should be che cked mo nth ly when cold and in-
Tire s an d wheel s 245
flated to the inflation pressure recommended
by the vehicle man ufact urer on the vehicle
placard or tire inflat ion pressure labe l. (If your
vehicle has tires of a different size than the
s ize indicated o n the vehicle placard or tire in­
flat ion pressure labe l, you shou ld determine
the proper t ire inflation pressu re for those
tires) .
As an added safety feature, your veh icle has
been equipped with a tire pressure monitoring
system ( TPMS) that illum inates a low tire
pr essure te lltale when one o r more of you r
tir es is s ignificant ly unde r-inflated. Acco rding ­
ly, when the low tire pressure tell tale illumi­
nates, you shou ld stop and check you r tires as
soon as possib le, and inflate them to the
proper pressure . Driving on a significant ly un­
der- inflated t ire causes the tire to overheat
and can lead to tire fa ilure. Under-inflation al­
so reduces fuel effic iency and tire tread life,
and may affect the vehicle's hand ling and
stopp ing abil ity .
Please note that the TPMS is not a substit ute
for proper tire ma intenance, and it is the driv­
er 's respons ibility to maintain correct tire
pressure, even if under-inflation has not
reached the level to tr igger illuminat ion of the
T PMS low ti re p ressu re tellta le.
Your vehicle has also been equipped with a
T PMS ma lfunction ind icator to ind icate when
the system is not operating p rope rly . T he
T PMS ma lfun ction indicator is comb ined w ith
the low tire pressure te lltale . Whe n the sys ­
tem detects a malfunc tion, the telltale will
flash for approximate ly one mi nute and then
remain continuously i lluminated. T his se­
quence will continue upon subsequent vehicle
start-ups as long as the malfunct ion exists .
When the malfunction indicato r is illum inat­
ed, the system may not be ab le to detect or
s ignal low tire pressure as intended. TPMS
malfu nctions may occur for a var iety of rea­
sons, including the installation of replace­
ment or a lternate tires or wheels on the vehi ­
cle that p revent the TPMS from functioning
properly. Always check the TPMS malfunction
t e llt ale after rep laci ng one or more tires o r ..,.
