temperatures stay below freezing point for long periods.
Detergent additives in the oil 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.
Damage or malfun ctions due to lack of
maintenance
It is essential that you change your oil at the
recommended intervals 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 booklet . 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 timely 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, all in­
ternal combustion eng ines consume a certain
amount of oil. O il consumption varies from
engine to engine and may change significantly
over the life of the engine. Typically, engines
with a specif ied 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 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 oxida­
tion level of the oil. 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 all 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
Ill 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¢
A in Working in the engine
compartment on page 214.
(D Note
Driving w ith an insufficient o il level is like­
ly to cause severe damage to the engine .
(D 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, pref­ erably 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 consult an author­
ized Audi dealer to have the cause of
your concern properly diagnosed. Keep in
m ind that the accurate measurement of
oil consumption requ ires great care and
may take some time. An authorized Aud i
dea ler has instructions about how to
measure oil consumption accurately.

238 Tire s and whee ls
- Adjust the tire pressure to the load you are
carrying.
- Reinsta ll the va lve stem cap on the valve .
When should I ch eck the tire pres sur e?
The correct tire pressure is especially impor­
tant at high speeds. The pressure should
therefore be checked at least once a month
and a lways before starting a journey. Do not
forget to check the tire pressure for the spare
wheel.
When should I adj ust the tire p re ss ures?
Adjust the tire pressure to the load you are
carry ing . After changing a wheel
o r replacing
wheels you have to adjust the tire pressures
on all wheels . In addition, you must then initi­
alize the new tire pressures in the tire pres­
sure monitoring system*~
page 249.
A WARNING
Incorrect tire pressures and/or underinf la­
tion can lead sudden tire failure, loss of
control, collision, ser ious personal injury
or even death.
- When the
RI] warning symbol appears in
the instrument cluster, stop and inspect
the tires .
- Incorrect tire pressure and/or underinfla­
t ion can cause increased t ire wear and
can affect the handling of the veh icle and
stopp ing ability.
- Incorrect tire pressures and/or underin­
flation can also lead to sudden tire fa il­
ure, including a blowout and sudden de­
flation, causing loss of vehicle control.
- The driver is responsible for the correct
t ire pressures fo r all tires on the vehicle .
T he applicable p ressure va lues are locat­
ed on a sticker on the driver's side B-pil ­
lar.
- Only when a ll ti res on the vehicle are fi l­
led to the correct pressure, the tire pres­
sure monitoring system* can work cor­
rect ly.
- The use of incorrect tire pressure values
can lead to accidents or other damage.
Therefore it is essential that the driver observe the specified t
ire pressure values
for the tires and the correct pressures for
the function of the ti re pressure monitor­ing system*.
- Always inflate tires to the recommended
and correct t ire pressure before dr iv ing
off.
- Driving with underinflated tires bend
more, letting them get too hot resulting
in tread separation, sudden tire failure
and loss of control.
- Excessive speed and/overloading can
cause heat build-up, sudden tire failure
and loss of cont rol.
- If the tire pressure is too low or too high,
the t ires will wear prematurely and the
veh icle w ill not handle well.
- If the tire is not flat and you do not have
to change a wh eel immediately, drive at
reduced speed to the nearest service sta­
tion to check the t ire p ressure and add
air as required.
Q) Note
D riving without valve stem caps can cause
damage to the tire valves. To prevent this,
a lways make sure tha t factory insta lled
valve stem caps on all whee ls are sec urely
mounted on the valve.
@ For the sake of the environment
U nderinflated tires w ill also incre ase the
fuel consumption .
Tires and vehicle load limits
There are limits to the amount of load or
weight that any veh icle and any tire can carry.
A vehicle that is over loaded will not handle
well and is more d iff icult to stop. Overloading
can not only lead to loss of vehicle control,
but can also damage important parts of the
vehicle and can lead to sudden tire fa ilure, in­
clud ing a b lowout and sudden deflation tha t
can cause the vehicle to crash.
Your safety and that of your passengers also depends on making sure that load limits are .,..

Tire pressure monitoring system
UJ General notes
Applies to vehicles: with tire pressure monito ring system
Each t ire, i ncluding the spare (if provi ded),
should be chec ked month ly w hen cold and in­
flated to the inflation pressure recommended by the vehicle manufacture r o n the vehicle
placar d or tire infla tion pressure label. (If your
veh icle has t ires of a diff erent siz e than the
size ind icat ed on the vehicle p lacard or tir e in ­
flation pressure label, you should deter mine
the proper tire inflation pressure for those
tires).
As an added safety feature, your vehicle has been equipped with a tire pressure monitor ing
system (TPMS) that illuminates a low tire
pr essu re tellta le when one or mo re of your
tires is significantly under -inflated . Accord ing ­
l y, when the low tire p ress ure telltale illumi­
nates, you should stop and check your tires as
soon as possible, and inflate them to the
proper pressure. Driv ing on a signif icantly un­
der-inflated tire causes the tire to overheat
and can lead to tire failure. Under -inflation al ­
so reduces fuel efficiency and tire t read life,
and may affect the ve hicle's handling and
stopping ab ility.
Please note that the TPMS is not a subst itute
for p roper t ire mainte nance , and it is the dr iv­
e r's responsib ility to ma inta in cor re ct t ire
p ress ure, even if under- infla tion has no t
reached the leve l to trigger ill umin ation of the
TPMS low tire pressure telltale.
Your veh icle has also bee n equ ipped with a
TPMS malfunc tion indica to r to indica te when
the system is not opera ting properly. The
TPMS mal function indicato r is combined wi th
the low tire press ure tellta le . When the sys­
tem detects a malf unct ion, the te lltale will
flash for approximately one minute and then remain cont inuo usly illuminated. This se­
quence will continue upon subsequent vehicle
start-ups as long as the ma lf u nction ex ists .
Tire s an d wheel s 249
When the malfunction indicator is illum inat ­
ed , the system may not be ab le to detect or
s ignal low tire pressure as intended . TPMS
malfunctions may occur for a var iety of rea­
sons, including the insta llation of replace­
ment or alternate tires or wheels on the vehi ­
cle that p revent the TPMS from functioning
proper ly. Always check the TPMS malfunction
te lltale after rep laci ng one or more tires o r
whee ls on you r vehicle to e nsur e th at the re­
placement or alterna te t ires and wheels a llow
the TPMS to continue to func tion p roperly.

A WARNING
- If the tire pressure indicator appears in
the instrument cl uster d isplay, one or
more of your tires is s ignificantly under­
inflated. Reduce your speed immediately
and avoid any hard steering or braki ng
maneuvers. Stop as soon as possible and
check the t ires and the ir pressures. In­
flate the tire pres sure to the proper p res­
s u re as in dic ated on the vehicle 's t ire
pressure label¢
page 234 . Driving on a
significantly under-inf lated tire ca uses the tire to overheat and can
lead to tire
fa ilure. Under-inflation also is likely to
impair the vehicle's handling and stop­
ping ability.
- The driver is responsible for maintaining
the correct tire pressures. You must
check the tire pressures regu larly .
- Under certain conditions (such as a spor­
ty driving style, winter conditions or un­ paved roads), the pressure monitor indi ­
cato r may be delayed .
-Ask your authorized Aud i dea ler if run­
flat t ires may be used on you r vehicle.
Your vehicle registration becomes invalid
if you use these t ires when not perm it­
ted. Damage to your vehicle or accidents
could a lso result.
(D Tips
- The tire pressure mon itoring system
stops work ing whe n there is an ESC/ABS
m alfu nction.
- Us ing snow chains may result in a system
ma lf u nction.
- The tire pressure mon itoring system on
your Audi was deve loped using tires with
t he "AO" or "R O" ident ifi cat ion on the
tire sidewa ll¢
page 242 . We recom ­
mend using these tires.
