from the housing . T
hen w ipe the MM I terminal wit h a clean, so ft, s light ly
dam p cloth.
The M MI termina l shou ld be c leaned w ith a brush first so that no
dirt is trapped between the buttons and the housing. We recom­
mend giving the MMI terminal a fina l w ipe with a c loth moistened
with water and dish washing detergent.

To prevent damage, make sure that no fluid ever gets into the MMI
terminal. •
Aluminum trim
Use only neutral -pH produc ts to remove spots and deposits from
aluminum surfaces. Chrome care products and alkaline cleaners
wi ll attack aluminum surfaces and can damage them over time.
& WARNING
Al way s read and h eed all WARNINGS and oth er information
=> page 31 2. •
Fabrics and fabric coverings
Fabrics and fabric coverings (e.g . seats, door trim panels, etc.)
shou ld be c leaned at regular inte rvals with a vacuum cleaner . This
removes surface dirt particles which could become embedded in
the fabric th rough use. Steam cleaners shou ld not be used, because
the steam tends to push the dirt deeper into the fabric and lock it
there .

current list of oils (manufacturers, brand names etc.) that conform
t o Audi oi l standard VW 502 00 .
Changin g the engine oil
The engine oil and oil filter must be changed according to the
mi leage (ki lometers) and time intervals specified in your vehicle's
Warranty
& Maintenance booklet. Do not exceed these interva ls -
harmful deposits from old engine oil can reduce engine perfor­
mance and can lead to expensive engine repairs.
Changing the oi l at the recommended intervals is so very important
because the lubricating prope rties of oi l decrease gradual ly during
normal vehicle use . If you are not sure when you have your oil
changed, ask your author ized Audi Serv ice Advisor.
Under some circumstances the engine oil should even be changed
more frequently. Change oil more often if you dr ive mostly short
distances, operate the vehicle in dusty areas or mostly under stop ­
and -go t raffic conditions, or when you use your vehicle where
temperatures stay be low freezing point for long per iods.
Detergent additives in the oil will make fresh oil look dark after the
engine has been running for a short time . This is normal and is not
a reason to change the oil more often than recommended.
Damag e or malfunctions due to lack o f mainten anc e
It is essentia l that you change your oi l at the recommended interva ls
using on ly engine oil that complies with Audi oil standard
VW 502 00. Your Limited New Vehicle Warranty does not cover damage or ma lfunctions due to failure to follow recommended
main tenance and use requirements as set forth in the Aud i Owner's
Manual and Warranty
& Maintenance booklet. Your dealer wi ll have
t o deny warranty cove rage unless you present to the dealer p ro o f in
the form of Service or Repair Orders that all schedu led maintenance
was pe rformed in a timely manner. •
Engine oil consumption
The engine in your vehicle depends on an adeq uate
amount of oil t o lubric ate and c ool all of its m oving parts.
In order to provide effective lubrication and coo ling of interna l
engine components, al l interna l combustio n eng ines consume a
certain amount of oil. Oil consumption varies from engine to engine
and may change significant ly over the life of the engine . Typ ically,
engines with a specified break-in period (see=>
page 2971 consume
more oil du ring the break-in period than they consume after oil
consumption has stabi lized .
Unde r normal conditions, the rate of oil consumption depends on
the quality and v iscosity of the oil, the RPM (revolutions per minute)
at which the engine is operated, the ambient temperature and road
cond itions. Fur ther factors are the amount of oil di lu tion from wate r
condensation or fue l residue and the oxidation leve l of the oi l. As
any engine is subject to wear as mileage bu ilds up, t he oil consump ­
tion may increase over time until replacement of worn components
may become necessa ry .
With all these variables coming into play, no standard rate o f oi l
consumption can be established or specified . There is no alternative
t o regula r and frequent checking of the oil level, see
Note .
If the yel low engine oil level warning symbo l in the instrument
clus ter lights up, yo u should check the oil level as soon as
possible
with the oil dipstick=> page 335. Top off the oil at your
ea rliest convenience =>
page 336.
& WARNING
Before you check anything in the engine compartment , always
read and heed all WARNING S
=> & in "Working in the engine
compartment " on
page 331.

- Read the engine coolant level in the open coolant expan­
sion tank :::::>
page 338, fig. 287. With a cold engine, the
coolant level should be between the "min" and "max"
markings. When the engine is warm, the level may be
slightly above the "max" marking.
The location of the coolant expansion tank can be seen in the
engine compartment illustration~
page 332.
To obtain an accurate reading, the engine must be switched off.
The expansion tank in your vehicle is equipped with an electric
coolant level sensor.
When the coolant level is too low, the warning light in the Auto­
Check System~
page 33will blink until you add coolant and the
level has been restored to normal. Even though there is an electric
coolant level sensor, we still recommend you check the coolant level
from time to time .
Coolant loss
Coolant loss may indicate a leak in the cooling system . In the event
of coolant loss, the cooling system should be inspected immedi­
ately by your authorized Audi dealer . It is not enough merely to add
coolant.
In a
sealed system, losses can occur only if the boiling point of the
coolant is exceeded as a result of overheating.
& WARNING
The cooling system is under pressure and can get very hot. Reduce
the risk of scalding from hot coolant by following these steps.
• Turn off the engine and allow it to cool down.
• Protect your face, hands and arms from escaping fluid and
steam by covering the cap with a large, thick rag.
& WARNING (continued)
• Turn the cap slowly and very carefully in a counter-clockwise
direction while applying light, downward pressure on the top of
the cap .
• To avoid being burned, do not spill antifreeze or coolant on the
exhaust system or hot engine parts. Under certain conditions, the
ethylene glycol in engine coolant can catch fire.
0 Note
Do not add any type of radiator leak sealant to your vehicle's engine
coolant. Adding radiator repair fluid may adversely affect the func ­
tion and performance of your cooling system and could result in
damage not covered by your New Vehicle Limited Warranty. •
Adding coolant
Be very careful when adding engine coolant.
Before you check anything in the engine compartment,
always read and heed all WARNINGS:::::> & in "Working in
the engine compartment" on
page 331.
- Turn off the engine.
Let the engine cool down.
Place a thick rag over the coolant expansion tank
=:> page 338, fig. 287 and carefully twist the cap counter­
clockwise :::::>& .
Add coolant.
- Twist the cap on again
tightly.

- Read the brake fluid l eve l from the brake fluid reservoir
=> fig. 288. The brake flu id level mus t be between the
"MIN" and "MAX" markings.
The brake fluid reservoir is locate d at the rear partition of the engine
compartment on the left side=>
page 332.
The fluid level may drop slightly after some time due to the auto ­
ma tic adjustment of the brake pads. This is not cause for alarm .
If the brake fluid leve l falls
considerably below the "MIN" mark , the
brake warning/indicator light (U.S. models:
BRAKE , Canadian models:
«D> l will come on=>
page 23 and=> page 32 . Do not continue to
operate the vehicle. The complete brake system should be thor ­
oughly checked
by an author ized Audi dealer or qua lif ied workshop
and the cause corrected . If th e brake fluid level is too low, the brake
warning/indicator light w ill illumi nate. Contact an authorized Audi
dea ler
immedi ately .
[ i ] Tips
The brake fluid reservoir is located underneath the cover .•
Changing brake fluid
Have the brake fluid changed by an experience d techni ­
cian.
Brak e fluid absorbs mois ture from the air. If the wate r conten t in the
brake fluid is too high, corrosion in the brake sys tem may res ult
after a period of time . The boiling point of the brake fluid will also
decrease conside rably and decrease braking performance .
Therefore , the brake fluid mus t be changed
every two year s. Always
use new brake fluid which conforms to Federal Motor Vehicle S tan ­
da rd "FMVSS 116 DOT 4".
The brake fluid reservoir can be difficul t to reach, therefore , we
recommend that y ou have the brake fluid changed by your autho ­
rized
Audi deal er. Your dealer has the correct tools, the right brake
fluid and the know -how to do this for you .
& WARNING
• Brak e fluid is poi sonou s. It mu st be stored only in the clo sed
o riginal conta iner out of the rea ch of children! ..,.
