Engine oil
Engine oil specifications
The engine in your Audi needs the right kind
of oil.
The engine in your Audi is a sophisticated
powerplant that was built to exacting spec ifi­
cations . Th is eng ine needs the right k ind of
engine oil that meets specifications regardi ng
quality and viscosity so that it can run
smooth ly and reliab ly. Choosing the right o il
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 deve loped
a spec ia l quality standard for engine oil that
will help assure that your vehicle's engine w ill
get the lubrication it needs for proper opera­
tion.
Modern engine lubrication has taken a quan ­
tum leap in the last few years. Many synthetic

C han gin g the en gin e o il
The engine oil and oil filter must be changed
according to the m ileage (ki lomete rs) and
time inte rva ls specified in your vehicle 's War­
r anty
& M aintenance booklet. Do not ex ceed
t hese intervals -harmf ul depos its from old
engine oi l can reduce engine performance and
can lead to expensive engine repairs.
Changing the o il at the recommended inte r­
va ls is so very important because the lub ric at­
ing p roperties o f oi l decrease grad ually during
norma l vehicle use . If you are not sure when
you have yo ur oi l changed, ask your a uthor­
ized A udi Service Advisor.
Unde r some ci rc u mstances the engine o il
should even be changed more frequently.
Change o il more often if you drive mostly
short distances, operate the vehicle in dusty
areas or mostly under stop-and-go traffic con­
d itions, or when you use your vehicle where
temperatures stay below freezing po int for
l ong periods .
Detergent addit ives in the o il w ill make fresh
oil look dark after the eng ine has been run­
ni ng fo r a short time . This is no rmal and is not
a reason to change the o il mo re often than
r ec om mended.
Damage or malfun ctions due to lack of
maintenance
It is essential that yo u change your oil at the
recommended interva ls using only engine oil
that complies with Audi oi l standard

· Engine oil consumption
To provide effective l ubr ication and cooling for
interna l eng ine parts, all interna l combustion
engines use some oi l. Oi l consumption varies
from eng ine to engine and may change over
the life of the engine . Engines tend to use
more o il du ring the b reak-in period tha n they
do afterward, when o il cons umption has sta­
bilized. Depend ing on the way the vehicle is
driven and the operating conditions, oil con­
s u mption can be up to
1 quart per 1,200
miles (l liter per 2,000 km) . Consumption
may be higher within the first
3,000 m iles
(5,000 km) .
U nder normal conditions , the rate of oi l con ­
s u mption depends on oi l quality as well as vis­
cosity, engine speed (rpm), outs ide tempera ­
ture, road conditions, the amount of oil dilu­
tion caused by condensed water or fue l resi­
due, and ox idat ion of the o il. Oi l consumption
may increas e with eng ine wear over time, un­
t il rep lacement of worn engine pa rts may be­
come ne cessa ry.
Because of all these var iables, there is no
standard o r "n orma l" rate of o il cons umption .
We urge you to check the engine oil level at
regular interval s, preferably every time y ou
fill the fuel t ank, and always before a long
trip .
The oil pres sure warning light. i s not an
indicator of low engine oil level. If the warn ­
ing light does not go out after starting, or
flashes while dr iving (above 1500 rpm), a
buzzer will sound. It indicate s that the oil
pressure is too low . Stop the engine immedi ­
ately , check the engine oil level and add oil if
necessa ry. If the engine oil level is normal,
but the l ight continues to fla sh, do not keep
driving or let the engine idle, as damage may
occur .

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.
Fig. 251 Tire tread: tread wear indicators (TWI)
Fig. 252 Rotating tires for more even wear
Tread Wear Indicator (TWI)
The original tires on your vehicle have
1/16 inch (1.6 mm) high "wear indicators"
c::> fig. 251 running across the tread. Depend­
ing on the make, there will be six to eight of
them evenly placed around the tire. Marks on
the tire sidewall (for example "TWI" or other
symbols) indicate the positions of the tread
wear indicators . Worn tires must be replaced.
Different figures may apply in other countries
c::> &. .
Tire pressure
Incorrect tire pressure causes premature wear
and can cause sudden tire blow-out . For this
Tires and wheels 283
reason , tire pressure must be checked at least
once a month
c::> page 2 79.
Driving style
Driving fast around curves, heavy acceleration
and hard braking increase tire wear .
Rotating tires for more even wear
For all four tires on your vehicle to have the
same service life, we recommend that the
front and rear tires are rotated according to
the tire manufacturer's suggested tire rota­
tion intervals. Please remember the follow­
ing:
- Tire rotation intervals may differ from the
vehicle service intervals outlined 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 manufacturer's suggested
tire rotation intervals.
- Vehicles with front-wheel drive experience
more tread wear on the front wheels com­
pared to all-wheel drive (q uattro).
- Please rotate tires as shown
c::> fig. 252.
-Extra care must be taken when rotating di-
rection-specific tires
c::> page 301.
Wheel balancing
The wheels on new vehicles are balanced .
However, various situations during everyday
driving can cause them to become unbal­ anced, resulting in vibrations you can usually
feel through the steering wheel.
Unbalanced wheels must be rebalanced to
avoid excessive wear on steering, suspension
and tires. A wheel must also be rebalanced
when a new tire is installed.
Incorrect wheel alignment
Incorrect wheel alignment can cause exces­
sive tire wear, impairing the safety of the vehi­
cle.
If tires show excessive wear, have the
wheel alignment checked by an authorized
Audi dealer or qualified workshop.

What you can do to avoid tire and rim
damage
L ow aspect ratio tires can be damaged more
easi ly by impact with potho les, curbs, gu llies
or ridges on the road, particularly if the tire is
underinflated.
I n order to minimize the occurrence o f 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
t ires or have them inspected by the nearest
authorized Aud i dealer . Replace a damaged
t ir e 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 unde rinflation, wh ich could eventu­
ally cause tire failure. If you be lieve that a
tire may have been damaged, replace the
tire as soon as possible.
- These tires may wea r more quickly than oth­
ers.
- Please also remember that, while these tires
deliver responsive handling, they may ride
less comfortably and make more noise 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 veh icle 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
Tires and wheels 2 91
you drive under those ci rcumstances, you
shou ld equip your vehicle with all-season or
winter tires, which offer better traction under
those conditions. We suggest you use the rec­ ommended snow or all-season t ires specified
for your vehicle, or their equivalent .
Refer to
¢ page 288 for more detailed infor­
mation regarding winter tires .
Tire pressure
monitoring system
ill General notes
Each tire, incl uding 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 veh icle
placard or tire inflation pressure label. (If your
vehicle has tires of a d ifferent size than the
s iz e indicated o n the vehicle placard or tire in­
flat io n pressu re lab el, you sho uld determine
the p roper tire inflation pressure for those
tires).
As an added safe ty feature, your veh icle has
been equipped with a tire pressure monito ring
system ( TPMS) that illuminates a low ti re
pressure telltale when one or more of your
tires is significantly under-inflated. According­
l y, when the low tire pressure te lltale 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 fa ilure. Under-inflation al­
so reduces fuel efficien cy and tire tread life,
and may affect the vehicle's hand ling and
stopping ability .
Please note that the TPMS is not a subst itute
for proper tire maintenance, and it is the driv­
er's responsibility to maintain correct tire
pressure, even if under-inflation has not
reached the leve l to tr igger illumination of the
T PMS low tire pressure tellta le .
Your vehicle has also been eq uipped with a
T PMS ma lfunction indicator to indicate when
the system is not operating properly. The

Maintenance
General
Your vehicle has been designed to help keep
maintenance requirements to a minimum.
However, a certain amount of regular mainte­
nance is still necessary to assure your vehicle's
s afety, economy and rel iability. For detailed
vehicle maintenance consult your Warranty &
Maintenance booklet.
Under difficult operating conditions, for ex­
ample at extremely low outside temperatures,
i n very dusty regions , when towing a trailer
very frequently, etc., some service work
should be performed between the intervals
specified. This applies particularly to:
- oil changes, and
- cleaning or replacing the air filter .
(® For the sake of the environment
By regularly maintaining your vehicle, you
help make sure that emission standards
are maintained, thus minimizing adverse
effects on the environment.
Important considerations for you and
your vehicle
The increasing use of electronics, sophisticat­
ed fuel injection and emission contro l sys-
tems, and the genera lly increasing technical
liJJ,

complexity of today's automobi les, have
steadi ly reduced the scope of maintenance
and repairs which can be carried out by vehicle
owners.
Also, safe ty and e nvir onm en tal con­
cerns p lace very strict limits on the na ture of
repairs and adjustments to engine and trans ­
miss io n pa rts which an owner can perform .
Maintenance, adjustments and repa irs usua lly
require special tools, testing dev ices and oth­
er equipment avai lab le to specially trained
workshop personnel in order to assure prope r
performance, reliab ility and safety of the vehi­
cle and its many systems .
Improper ma intenance, adjustments and re ­
pa irs can impair the operation and reliability
of your vehicle and even void your vehicle war­ ranty. The refo re, p roof of servici ng in accord­
ance w ith the maintenance sched ule may be a
condition for upholding a poss ible war ranty
claim made within the warranty period.
Above all, operational safety can be adversely
affected, crea ting unnecessary risks for you
and your passengers.
If in doubt about any servicing, have it done
by your authorized Audi dealer or any other
properly equipped and q ualified workshop .
We strong ly urge you to give you r a uthorized
Audi dealer the opportunity to perform all
schedu led maintenance and necessary repairs .
Your dea ler has the facilities, or iginal parts
and trained spec ialists to keep your vehicle
running properly .
Performing limit ed m aintenance you rself
The following pages describe a limited num­
ber of procedures which can be performed on
your vehicle with ordinary too ls, should the
need arise and trained personnel be unavaila­
b le. Before performing any of these proce­
dures, always thoroughly read all of the app li­

A WARNING
-Ser ious personal injury may occur as a re­
sult of improperly performed mainte­ nance, adjustments or repa irs.
-Always be extremely careful when work­ ing on the vehicle. Always follow com­
mon ly accepted safety pract ices and gen­
eral common sense . Never r isk personal
lnJUry .
- Do not attempt any of the ma intenance ,
checks or repairs descr ibed on the fol­
lowing pages if you are not fully fam iliar
wit h these or othe r pro cedures with re­
spect to t he veh icle, or are uncerta in how
to p roceed .
- Do not do any work without the proper
too ls and equipment. Have the necessary
work done by your authorized A udi deal ­
er or another proper ly equipped and
qualified workshop .
- The engine compartment o f any motor
veh icle is a potentially hazardous area.
Never reach into the area around or
touch the rad iator fan. It is temperature
contro lled and can switch on suddenly -
even when the engine is
off and the igni­
tion key has been removed. The rad iator
fan switches on automat ica lly when the
coo lant reaches a certai n temperatu re
and will cont inue to run until the coo lan t
tempera ture drops .
- Always remove the ign ition key befo re
anyone gets under the vehicle.
- Always support your veh icle with safety
s tands i f it is necessary to work under­
neath the vehicle. The jack s upplied with
the vehicle is not adequate for this pur ­
pose and cou ld collapse causing serio us
personal injury.
- If you must work underneath the vehicle
with the wheels on the ground, a lways
make sure the vehicle is on leve l ground,
that the wheels are a lways securely
blocked a nd that the engine cannot be
started .
