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.

.,.Audi recommends that you use
Audi Original Tires. If you would like to use different tires, please
note that the tires may perform
differently even if they are the
same size
¢ 11:,. .
.,. If you would like to equip your
vehicle with a tire/rim combina­
tion that is different from what
was installed at the factory, con­
sult with an authorized Audi dealer or authorized Audi Service
Facility before making a pur­
chase¢ ,&.
Because the spare tire* is differ­
ent from the regular tires instal­
led on the vehicle (such as winter
tires or wide tires), only use the
spare tire* temporarily in case of
emergency and drive carefully
while it is in use. It should be re­
placed with a regular tire as soon
as possible.
Applies to: vehicles with all wheel
drive: all four wheels must be
equipped with tires that are the
same brand and have the same
construction and tread pattern so
that the drive system is not dam­
aged by different wheel speeds. For this reason, in case of emer­
gency, only use a spare tire* that
338
is the same circumference as the
regular tires.
~ WARNING -
-Only use tire/rim combina­ tions and suitable wheel bolts
that have been approved by
Audi. Otherwise, damage to
the vehicle and an accident could result.
-For technical reasons, it is not possible to use tires from oth­
er vehicles - in some cases,
you cannot even use tires from
the same vehicle model.
-Make sure that the tires you
select have enough clearance
to the vehicle. Replacement
tires should not be chosen simply based on the nominal
size, because tires with a dif­
ferent construction can differ
greatly even if they are the
same size. If there is not
enough clearance, the tires or
the vehicle can be damaged and this can reduce driving
safety and increase the risk of
an accident.
-Only use tires that are more than six years old when abso­
lutely necessary and drive
carefully when doing so.
