Detergent add it 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.
Dam age or ma lf u ncti ons 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. You r 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 maintenance
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 comb ustion 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 197) 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
sumpt ion depends on the quality and viscosity
of the oil, the RPM (revolutions per m inute) 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
in the instrument cluster
m lights up, yo u
shou ld check the oil leve l as soon as possib le
¢
page 22 7. Top off the oil at your earliest
convenience ¢

A WARNING '"---
Before you check anything in the engine
compartment, always read and heed all
WARNINGS¢
A in Working in the engine
comportment on page 222.
(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 indicator of the oil le vel. Do not
r el y on it . In ste ad, ch eck the oil lev el in
y our engin e at regular inter vals , pref ­
erably ea ch time you r efu el, and alway s
before going on a long trip .
-If you have t he impression yo ur engine
cons umes ex cessive amoun ts of o il, we
recommend that you consu lt your Aud i
dea ler to have the cause of your concern
properly diagnosed. Keep in mind that
the accurate meas urement of oi l con­
sumption requ ires great care and may
take some t ime. Your Audi dea ler has in­
structions about how to measure oil con­
sumption accurately.
-

-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 tire failure
and loss of vehicle control.
Glossary of tire and loading terminology
Accessory weight

mounted on the valve .
@ For the sake of the environment
Underinflated tires will also increase the
fue l consumption.
Tires and vehicle load limits
There are limits to the amount of load or
weight that any vehicle and any tire can carry.
A vehicle that is overloaded will not handle
well and is more difficult 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 failure, in­
cluding a blowout and sudden deflation that
can cause the vehicle to crash.
Your safety and that of your passengers also
depends on making sure that load limits are
not exceeded. Vehicle load includes everybody
and everyth ing in and on the vehicle. These
l oad limits are techn ica lly referred to as the
vehicle's
Gross Vehicle Weight Rating
("GVWR").
The "GVWR" includes the we ight of the basic
vehicle, all factory installed accessories, a full
tank of fuel , oil, coo lant and other fluids plus
maximum load. The maximum load includes
the number of passengers that the vehicle is
intended to carry ("seating capacity") with an
assumed weight of 150 lbs (68 kg) for each
passenger at a des ignated seat ing pos ition
and the tota l we ight of any luggage in the ve­
hicle. If you tow a trailer, the weight of the
trailer hitch and the tongue weight of the
l oaded trailer must be included as part of the
vehicle load.
The
Gross Axle Weight Rating ("GAWR") is
the maximum load that can be applied at each
of the vehicle's two axles.
The G ross Vehicle Weight Rating and the
Gross Axle Weight Rating are listed on the
safety compliance sticker labe l located on the
driver's side B-p illar. You r A udi has 5 seat ing
positions, 2 in the front and 3 in the rear for
total seating capacity of 5. Vehicles with pow- er individual rear seats* have
4 seating posi ­
tions,
2 in the front and 2 in the rear for total
seat ing capac ity of
4. Each seating position
has a safety belt¢
page 137, Safety belts.
The fact that there is an upper limit to your
vehicle's Gross Vehicle Weight Rating means
that the total weight of whatever is being car­
ried in the vehicle (including the weight of a
trailer hitch and the tongue weight of the
loaded trailer) is lim ited . 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 max imum combined weight of a ll of the
occupants and luggage or other cargo that
the vehicle can carry. For the location of the
label¢
page 242, fig. 184.
A WARNING ,___
Overloading a vehicle can cause loss of ve­
h icl e contro l, a crash or other accident, se­
rious personal injury, and even death.
- Carrying more weight than your vehicle
was designed to carry will prevent the
vehicle from handling properly and in­
crease the risk of the loss of vehicle con­
trol.
- The brakes on a vehicle that has been
overloaded may not be able to stop the
veh icle with in a safe distance.
- Tires on a vehicle that has been overload­
ed can fail suddenly, including a blowout
and sudden deflation, causing loss of
control and a crash.
- Always make sure that the total load be­
ing transported -including the weight of
a trailer hitch and the tongue we ight of a
loaded trailer -does not make the vehi­
cle heavier than the vehicle's G ross Vehi­
cle Weight Rating.

256 Tires and wheels
or ridges on the road, particularly if the tire is
underinflated.
I n o rder to minim ize the occurrence of impact
damage to the tires of your vehicle, we recom­
mend that you observe the following precau ­
tions:
- Always maintain recommended inflation
pressures. Check your tire pressure every
2,000 miles (3,000
km) and add air if neces­
sary.
- Drive carefully on roads with potholes, deep
gullies or ridges. The impact from driving
through 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 Audi dealer. Replace a damaged
tire as soon as possible .
- Inspect your tires 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 tire failure . If you be lieve that a
t ir e may have been damaged, replace the
t ir e as soon as possible.
- T hese tires may wear mo re quick ly than oth­
ers.
- Please also remember that, while these t ires
deliver respons ive handling, they may ride
less comfortably and make more no ise than
other choices.
Reduced performance in winter/cold
season conditions
All tires are designed for certain purposes.
The low aspect ratio, ultra high performance
tires originally installed on your vehicle are in­
tended for maximum dry and wet road per­
formance and handling. They are not suitable
for cold, snowy or icy weather condit ions. If
you drive under those circumstances, you should equip your vehicle with all -season or
winter tires, which offer better traction under
those cond it ions. We suggest you use the rec­
ommended snow or all-season tires specified
for your vehicle, or their equivalent. Refer
to
q page 253 for more detailed infor­
mation regarding winter tires.
Tire pressure monitoring system
(D General notes
Applies to veh icles: w ith tire pressure monitoring system
Each tire, including the spare ( if provided),
shou ld be checked monthly when co ld and in­
flated to the inflation pressure recommended
by the veh icle manufacturer on the vehicle
placard or tire inflation pressure label. (If your
vehicle has tires of a different size than the
s ize indicated on the vehicle placard or tire in­
flation pressure label, you should dete rmine
the proper tire inflation p ressure fo r those
t i res).
As an added safety feature, your veh icle has
been equipped with a tire pressure mon itoring
system (TPMS) that illuminates a low tire
pressure tel ltale when one or more of your
tires is significant ly under-inflated. According­
ly, when the low tire pressure telltale illumi­
nates, you should stop and check your tires as
soon as possible, and inflate them to the
proper pressure. Driving on a sign ificantly un­
der-inflated t ire causes the tire to overheat
and can lead to tire failure . Under-inflation al ­
so reduces fuel efficiency and tire tread life,
and may affect the vehicle 's handling and
stopp ing ability.
Please note that the TPMS is not a substitute
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 trigger illuminat ion of the
TPMS low tire pressu re tellta le .
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate when
the system is not operating properly. The
T PMS ma lfunction indicator is combined with
the low tire pressure telltale. When the sys­
tem detects a malfunction, the telltale will
flash for approximately one minute and then ..,_
