Engine oil
Engine oil specifications
The engine oil used in your Audi needs the
right kind of oil.
The engine in your Audi is a sophist icated
powerplant that was built to exacting specifi­
cations. This engine needs the right kind of
engi ne oil that meets specifications regard ing
quality and v iscosity so that it can run
smooth ly and reliab ly. Choosing the right oil
and changing oil within the time and mileage
intervals printed in your vehicle's Warranty
&
Maintenance booklet matters a lot more to­
day than it did years ago . Audi has developed
a spec ia l quality standard for eng ine oil that
will help assure that your vehicle's engine w ill
get the lubrication it needs for proper opera­
t ion .
Modern engine lubr ication has taken a quan ­
tum leap in the last few years. Many synthetic "'

-Never mount used tires on yo ur vehicle if
you are not sure of their "previous histo­
ry." Old used tires may have bee n 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
means the comb ined weight (in excess of
those standard items wh ich may be rep laced)
of automati c transmission, power steering,
power br akes, power wi ndows, power sea ts,
radio, and heater, to the ex tent that these
items are avai lab le as factory -installed equip­
ment (whether installed or not).
Aspect ratio
means the ratio of the height to the w idt h of
the tire in percent. Numbers of 55 or lower in ­
d icate a low sidewall fo r improved s teer ing re­
sponse and better overall handling on dry
pavement.
Bead
means the pa rt of the t ire that is made of
s teel wires, wrapped or re inforced by ply cor ds
and that is shaped to fit the r im.
Bead separation
means a b reakdown of the bond between
components in the bead.
Cord
means the strands forming the plies in the
tire.
Cold t ir e infl ation pr essure
means the tire pressure recommended by the
vehicle manufacturer for a t ire of a designated
size that has not been dr iven for more than a
couple of miles (kilometers) at low speeds in
the three hour period before the tire pressure i s measu red or adjusted.
Tire s an d wheel s 281
-If you notice un usua l vibration or if the
veh icle pulls to one side when driv ing, a l­
ways stop as soon as it is safe to do so and check the wheels and tires for dam­
age.
Curb weight
mea ns the weight of a motor ve hicle w ith
standard equipment includ ing t he maximum
capa city of fuel, o il, and coolant, ai r cond i­
tion ing a nd addi tional weig ht o f optiona l
equipment .
Extra load tire
means a tire design to operate at higher loads
and at higher inflation pressures than the cor­
respondi ng s tanda rd tire. Extra load tires may
be identified as "X L", "xl", "EXTRA LOAD", o r
"R F" on the sidewall .
Gross Axle Weight Rating ( "GAWR ")
mea ns the load-carrying capacity of a single
axle system, measured at the tire-ground in­
te rfaces.
Gross Vehicle Weight Rating ( "GVWR ")
means the maximum total loaded we ight of
t h e ve hicle.
Groo ve
means the space between two adjacent tread
ribs.
Load rating (code )
means the maximum load tha t a t ire is rated
to carry for a given inflation pressure. Yo u
may not find this information on all tires be­
ca use it is not required by law.
Maximum load rating
me ans the load r ating for a tire at the maxi­
mum pe rm issi ble inflat ion pressure for that
ti re .

2 90 Tires and wheels
Tire service life
The service life of tires depends on a lot of
different things including proper installation
and balancing, correct tire pressure and driv­
ing style.
F ig. 2 53 Tire tread: tread wea r ind icators (TWI)
F ig. 25 4 Rotat ing t ires for more even wear
Tr ead Wear Indicator (TWI)
The o rigi na l t ires on your veh icle have
1/16 inch (1.6 mm) high "wear indicators"
.... N M
c::> fig . 253 running across the tread. Depend ­
ing on the make, there will be six to eight of
them evenly p laced around the t ire. Marks on
the tire sidewa ll (for example "TWI" or other
symbols) indicate the positions of the tread
wear ind icators . Worn t ires must be replaced .
Different fig ures may apply in o ther countries
c::> & .
Tire p ressure
Incorrect tire pressure causes premature wear
a nd can cause sudden t ire blow-out. For t his
reason, tire pressure must be checked at least
once a month
c::> page 2 86.
Driving style
Driving fast aro und curves, heavy acce leration
and hard braking increase tire wear.
Rotating tires for more even wear
F or all four tires on your ve hicl e to h ave the
same service life, we recommen d that t he
front and rear t ires are rotated according to
the tire manufact urer's suggested tire rota­
tion intervals. Please remember the follow­ ing:
- Tire rotation intervals may differ from the
vehicle service inte rva ls o utlined in your
Warranty
& Maintenance booklet.
- The longer one tire is used in one location
on the vehicle, the more it wears at certain
points; therefore, we recommend that you
follow the tire manufact urer's suggested
tire rotation intervals .
- Vehi cles w ith front-wheel dr ive experience
more tread wear on the fro nt w heels com­
pa red to all-wheel drive (quattro ®).
- Please rotate tires as shown
c::> fig. 254.
-Extra care must be taken when rotating di-
rection-specific tires
c::> page 308.
Wheel balancing
The wheels on new ve hicles are balanced .
However, various situations during everyday
driving can cause them to become unba l­
anced, resulting in vibrat ions you can usually
feel through the steer ing wheel.
Un balanced whee ls must be rebalanced to
avo id excessive wear on steering, suspension
and t ires. A whee l m ust also be reba lanced
when a new tire is insta lled.
Incorrect wheel alignment
Incor rect w heel alig nment can cause exces ­
sive tire wear, impairing the safety of the vehi ­
cle . If tires show excessive wear, have the
whee l alignment checked by an aut horized
Audi dealer or qualif ied workshop .
All-wheel drive
Vehicles with q uattro ® mus t always have tires
of the same size, construction and tread type.
For details see
c::>page 231. ..,.

300 Tire s and whee ls
and avoid any hard steering or braking
maneuvers. Stop as soon as possible and
check the tires and their pressures. In­
flate the tire pressure to the proper pres­
sure as indicated on the vehicle's t ire
pressure label~
page 284 . Driving on a
significantly under-inflated tire causes
the tire to overheat and can lead to tire
failure. Under-inflation also is likely to impair the vehicle's handling and stop­
ping ability.
- T he driver is responsible for ma inta ining
the correct tire pressures . You must
check the tire pressures regular ly.
- Under certain conditions (such as a spor­
ty driving style, winter conditions or un­paved roads), the pressure monitor ind i­
cator may be de layed.
- Ask your authorized Audi dealer if run­
flat tires may be used on your veh icle.
Your vehicle registration becomes invalid if you use these tires when not permit­
ted . Damage to your veh icle or acc idents
could also result .
(D Tips
-The tire pressure monitoring system
stops working when there is an ESC/ABS
malfunction .
- Using snow chains may result in a system
malfunction.
- The tire pressure monitoring system on
your Audi was developed using t ires with
the "AO" or "RO" identification on the
tire sidewall
Q page 291 . We recom­
mend using these t ires.
Reset tire pressure monitoring system
If the tire pressure is adjusted , wheels are ro­
tated or changed, the TPMS must be reset via
MMI.
.. Before resetting the TPMS, the current pres ­
sures of all four tires must correspond to
the specified val ues. Adjust the tire pressure
and reset the pressure i n the t ire p ressu re monitoring system according to the load
you are carrying
