Checking and Filling
If the recommended engine oil is not available,
in an eme rg enc y you may add a maximum of 1
quart(! liter) of ACEA C3 or API SN engine oil
one tim e until the next oil change.
F or more information on the correct engine oil
for your vehicle, contact an authorized Audi dea l­
er or authorized Audi Service Facility . Have the oil
changed by an authori zed Audi dealer o r author­
ized Service Fac ility .

(D If the engine oil leve l is just before the
mark ing
(D , then engine oil must be added .
See¢@.
@ Do not add engine oil.
(D Note
- T he engine o il level must not be below the
ma rking
(D , because this increases the risk
of engine damage.
- After add ing engine oil, the oil leve l must
not be above the marking @, because this
increases the risk of catalytic converter and/
or engine damage . Do not start the engine .
Contact an authorized Audi dealer or au­
thorized Audi Service Facility to have excess eng ine oil extracted if necessary .
(D Tips
- The engine oil consumption may be up to
0.5 quart/600 miles (0.5 liter/1,000 km),
depending on driving style and operating
conditions. Consumpt io n may be h igher
dur ing the fi rst 3,000 mi les (5,000 km) . Be­
c ause of this , the eng ine o il level must be
che cked regularly.
It is best to check each
t ime you refuel your vehicle and before long
drives .
- In order to prov ide effective l ubrication and
cooling of interna l engine components, a ll
internal combustion engines consume a cer ­
tain amount of oil. O il consumption varies
from engine to engine and may change sig­ nificantly over the life of the engine. Typi­
cally, eng ines with a specif ied break-in peri­
od consume more oil during the break-in pe ­
riod than they consume after o il consump­
t ion has stabilized .
- Under normal condit ions, the rate of oil
cons umption depends on t he quality and
viscosity of the oil, the RPM (revo lutions per
mi nute) at which the engine is ope rated, the
ambien t temperature and road conditions .
Further factors are the amount of oi l dilu­
tion from water condensation or fuel resi­ due and the oxidation level of the oil. As any
eng ine is subject to wear as m ileage builds
Ii>-

u. 00 .-< N l'­ N .-< 0 N > 00
up, the oil consumption may increase over
time unti l replacement of worn components
may become necessary .
- With a ll these variab les coming into p lay,
no standard rate of oil consumption can be
estab lished or specified. There is no alterna­
tive to checking the o il level regu larly and
frequently.
- If you have the impression your engine con ­
sumes excessive amounts of oil, we recom­ mend that you consult an authorized Aud i
dealer to have the cause of your concern properly d iagnosed . Keep in mind that the
accu rate measurement of oil consumption
r equ ires gre at ca re and may take some
time. An a uthorized Audi dea ler has instruc­
tions about how to measure oil consump ­
tion acc urately.

Check ing and F illing
Changing the engine oil
We recommend that have your oil changed by an
authorized Audi dealer or a qualified service sta­ tion.
Before you check anyth ing in the eng ine compart­
ment,
a lw ays re ad and h eed all WARNING S c> .&
in Working in the engine compartment on
page 318.
The engine oil must be changed accord ing to the
intervals specif ied in your Warranty
& Mainte­
nance booklet. This is very impo rtant because the
lubricat ing p ropert ies of o il d iminish gradually
du ring normal vehicle use.
Under some c ircumstances the eng ine o il should
be changed more frequently . Change oil more of­
ten if you d rive most ly short distances, ope rate
the vehicle in dusty areas or under predominant ly
stop -and-go traffic cond it ions, o r have yo ur vehi ­
cle where temperatures remain below freezing
for extended periods .
Detergent additives in the oil will make fresh o il
look da rk afte r th e e ng ine
has been run ning fo r a
short time. This is norma l and is not a reason to
change the oil more often than recommended.
Because of the prob lem of p roper d isposa l, along
with the special tools and necessa ry expe rt ise re ­
quired, we strong ly recommend that you have
your oil changed by an authorized
Audi dealer or
a qualified service station .
If you choo se to change your oil your self , please
note the fo llowing important information:
A WARNING
T o red uce the risk of personal injury if you
must c hange the engine oil in your veh icle
yourself:
- Wear eye protection .
-To reduce the risk of bu rns from ho t engine
oi l, let the engine cool down to the touch .
-
-When removing the o il drain pl ug with you r
fingers, stay as far away as possible . A lways
keep your forearm paralle l to the ground to
help prevent hot oi l from running down your
arm.
324
- Drain the oil into a container designed for
this purpose, one large enough to hold at
least the tota l amount of oil in your engine.
- Engine oil is poisonous. Keep it well out of
the reach of children.
- Continuous contact with used engine oi l is
harmf ul to your skin. Always protect your
skin by washing oil off thoroughly with soap
and water .
@ Note
Never mix oil additives with your engine oil.
These additives can damage your engine and
adverse ly affect your Audi Limited New Vehi­
cle Warranty .
{® For the sake of the environment
- Before chang ing your oi l, first make sure
you know where you can properly dispose of
the used oil.
- Always dispose of used eng ine o il properly.
Do not dump it on garden so il, wooded
areas, into open streams or down sewage
dra ins.
- Recycle used eng ine o il by tak ing it to a used
eng ine oi l collect ion fac il ity in your area, or
contact a service station .
Cooling system
Coolant
The engine cooling system is filled w ith a mixture
of purified water and coolant additive at the fac­
tory. This coolant must not be not changed.
The coo lant level is monitored thro ugh
the . in­
dicator light
c> page 25. However, we do recom­
mend occas ionally checking the coolant leve l
manually.
If you must add coo lant, use a mixture of water
and coolant additive . Mix ing the coo lant add itive
with dist illed water is recommended.
1111-

Checking and Filling
Coolan t loss usu ally indicates there is a leak. Im ­
m ed iately drive your v ehicle to an authorized
Aud i dea ler or authorized Aud i Serv ice Facility
and have the cooling system inspected. If the
coo ling system is not leaking, a loss can come
from the coolant boiling through overheating
and be ing pushed out of the cool ing system.
.&_ WARNING
- The coo ling system is under pressure . Do
not open the coolant expans ion tank cap
when the eng ine is ho t. This inc reases the
risk of burns .
- T he coo lant add itive and the coolant can be
d angerous to your healt h. For this reason,
keep the coolant in the origina l container
and away from children . There is a risk of
poisoning .
- When working in the engine compartment,
remember that the rad iator fan can switch
on even if the ign ition is switched off, which
increases the risk of in jury .
-
CD Note
Do not add coolant if the expansion tank is
empty . Air could enter the cooling system and
damage the engine. If this is the case , do not
cont inue driving. See an authorized Audi deal­
er or author ized Audi Service Facility for assis­
tance .

General information
~check your tires regularly for
damage (punctures, cuts, cracks
and bulges). Remove foreign ob ­
jects from the tire tread.
~ If driving over curbs or similar
obstacles, drive slowly and ap­ proach the curb at an angle.
~Have faulty tires or rims re­
placed immediately.
~ Protect your tires from oil,
grease and fuel.
~ Mark tires before removing
them so that the same running
direction can be maintained if
they are reinstalled.
~Lay tires flat when storing and
store them in a cool, dry location
with as little exposure to light as
possible.
_&. WARNING -
-Never drive faster than the maximum permitted speed
for your tires. This could cause
the tires to heat up too much.
This increases the risk of an
accident because it can cause
the tire to burst .
-Always adapt your driving to the road and traffic condi-
330
tions . Drive carefully and re­
duce your speed on icy or slip­
pery roads . Even winter tires
can lose traction on black ice.
(@ Note
-Please note that summer and
winter tires are designed for
the conditions that are typical
i n those seasons . Aud i recom­
mends using winter tires dur­
ing the winter months . Low
temperatures significantly de­
crease the elasticity of summ­
er tires, which affects traction
and braking ability. If summer
tires are used in very cold
temperatures, cracks can form
on the tread bars, resulting in
permanent tire damage that
can cause loud driving noise
and unbalanced tires.
-Burnished, polished or chromed rims must not be used in winter driving condi­
t ions. The surface of the r ims
does not have sufficient corro­
sion protection for this and
could be permanently dam ­
aged by road salt or similar
substances.

Glossary of tire and loading
terminology
Accessory weight
means the combined weight ( in
excess of those standard items
which may be replaced) of auto­ matic transmission , power steer ­
ing, power brakes, power win­
dows, power seats, radio, and
heater, to the extent that these
items a re available as factory- in­
stalled equipment (whether i n­
stalled or not) .
Aspect ratio
means the ratio of the height to
the width of the tire in percent .
Numbers of 55 or lower indicate a
low s idewall for improved steer­
ing response and better overall
handling on dry pavement.
Bead
means the part of the tire that is
made of steel wires, wrapped or
reinforced by ply cords and that is
shaped to fit the rim .
Bead separation
means a breakdown of the bond
between components in the bead .
Wheel s
Cord
means the strands forming the
plies in the tire .
Cold tire inflation pressure
means the tire pressure recom­
mended by the vehicle manufac ­
turer for a tire of a designated
size that has not been driven for
more than a couple of miles (kilo­
meters) at low speeds in the
three hour period before the tire pressure is measured or adjusted .
Curb weight
means the weight of a motor ve­
hicle with standard equipment in­
cluding the maximum capacity of
fuel, oil , and coolant, air condi­
tioning and additional weight of
optional eq uipm ent .
Extra load tire
means a tire designed to operate
at higher loads and at highe r in­
flation pressures than the corre­
sponding standard tire . Extra load
tires may be identified as "X L",
"xl", "EXTRA LOAD", or "RF" on
the sidewall.

vehicle's Gross Veh ic le Weig ht
R ati ng
("GVWR").
The "GVWR" includes the weight
of the basic vehicle, all factory in­
stalled accessories, a full tank of
fuel, oil, coolant and other fluids
plus maximum load. The maxi­
mum load includes the number of
passengers that the vehicle is in­
tended to carry ("seating capaci­
ty") with an assumed weight of 150 lbs . (68 kg) for each passen­
ger at a designated seating posi ­
tion and the total weight of any luggage in the vehicle. If you tow
a trailer, the weight of the trailer
hitch and the tongue weight of
the loaded trailer must be includ­
ed as part of the vehicle load .
The
Gro ss Ax le W eight Rating
("GAWR") is the maximum load
that can be applied at each of the
vehicle's two axles .
T he fact that there is an upper
limit to your vehicle's Gross Vehi­
cle Weight Rating means that the
total weight of whatever is being
carried in the vehicle (including
the weight of a trailer hitch and
the tongue weight of the loaded
trailer) is limited . The more pas­
sengers in the vehicle or passen -
344
gers who are heavier than the
standard weights assumed mean
that less weight can be carried as luggage .
The Gross Vehicle Weight Rating and the Gross Axle Weight Rat ing
are listed on the safety compli­
ance sticker labe l located on the
driver's side B-pillar.
1.8. WARNING
Overloading a vehicle can cause loss of vehicle control, a crash
or other accident, serious per­
sonal injury, and even death.
-Carrying more weight than your vehicle was designed to carry will prevent the vehicle
from handling properly and increase the risk of the loss of
vehicle control.
-The brakes on a vehicle that has been overloaded may not
be able to stop the vehicle
within a safe distance .
-Tires on a vehicle that has been overloaded can fail sud ­
denly, including a blowout and
sudden deflation, causing loss
of contro l and a crash.
-Always make sure that the to­ tal load being transported
