scalding from hot coo lant by following
these steps.
- Turn
off the engi ne and a llow it to cool
down.
- Protect your face, hands and arms from
escapi ng fl uid and steam by cover ing
the cap with a large, thick rag .
- Turn the cap slowly and very ca refully
i n a cou nte r-clockw ise dir ect ion while
a pply ing lig ht, downwa rd p ress ure on
the top of the cap.
- T o avo id being burned, do no t sp ill an­
tifree ze o r coolan t on t he exh aust sys­
tem or ho t engine parts . Un der certain
conditions, the ethylene glyco l in en­
gine coolant can catch fire .
- Antifree ze is poisono us. Always store an­
tifreeze in its or iginal co ntainer and we ll
o ut o f the reac h of children.
- If you drain the coolant , it must be
caught and safely stored in a p roper con ­
tainer clear ly marked "poison".
(D Note
- Coolant po llutes the env ironment and
could ca use a n engine fire . Excess coo l­
ant wi ll be forced out through the pres ­
sure re lief va lve in the cap when the en­
gine becomes hot.
- If, in an emergency, only water can be
added , the correct ratio between water
and antifreeze¢
page 219 must be re­
stored as soon as possib le .
@ For the sake of the environment
Drained coolant should not be re used . Al­
ways dispose of used c oolant while observ­
ing all envir onmental regulations .
Radiator fan
The radiator fan switches on automa tically by
itself
T he radiator fan is driven by the engine via the
V-be lt. The viscous clutch regulates the speed
of the fan according to the temperature of the
coolant .
Checkin g and fillin g 221
An auxiliary electric radiato r fan* sw itches on
and
off depending on coolant temperature
and othe r vehicle ope rat ing con ditions.
After yo u switc h the engi ne off, the aux iliary
f an can con tinue r unning for up to 10 minutes
- even with the ignition off. It can even switch
on again later by itself¢ & , if
- t he temperatu re of the engine coo lant rises
due to the heat b uild -up from the en gine in
the engi ne compartment, or
- the engine compartment heats up be cause
the vehicle is parked in intense sunlight.
A WARNING
- To reduce the risk of personal in jury nev­
er touch the radiator fan.
- The a uxiliary electric fan is temperat ure
contro lled and can switch on sud denly
even when the engine is not running.
- The a uxiliary radiator fa n switches on a u­
tomatically when the engine coo lant
reaches a certain temperature and will
continue to run until the coo lant temper­
ature drops .
Brake fluid
Checking brake fluid level
The brake fluid level can be checked with a
qui ck glance.
Fig. 17 9 En gin e compar tment: Cover o n the brak e flu­
i d reservoi r
Before you check anyth ing in the eng ine com­
partment ,
always re ad and heed all WARN­
INGS c::> ,& in Working in the engine compar t-
ment on page 212 . .,..

222 Check ing and filling
• Read the brake fluid leve l from the brake
fluid reservoir ¢
fig. 179, ¢ fig. 175. The
brake f lu id leve l must be between the "MIN"
and "MAX" markings.
The brake fluid reservoir is located at the rear partition of the engine compartment on the
left side ¢
page 214 .
The fluid level may drop slightly after some
time due to the automatic adjustment of the brake pads . This is not cause for alarm .
I f the brake fluid level falls
considerably be­
l ow the "MIN" mark, the brake wa rning/indi ­
cator light (U .S . mode ls:
1111 , Canadian
models :. ) will come on
¢ page 15. Do not
continue to operate the vehicle. The complete brake system should be thoroughly checked
by an authorized Audi dealer or qualified
workshop and the cause corrected . If the
brake fluid level is too low, the b rake war ning/
i ndicato r light w ill illuminate . Contact an au­
thor ized Audi dealer
imm ediately .
@ Tips
The brake f lu id reservoir is located unde r­
neath the cove r.
Changing brake fluid
Have the brake fluid changed by an experi­
enced technician .
Brake fluid absorbs moisture from the a ir . If
the water content in the brake fluid is too
h igh, corrosion in the brake system may result
after a per iod of t ime . The bo iling po int of the
b rake fluid w ill also decrease considerably and
dec rease braking per formance.
Therefore, the brake flu id must be changed
e ver y two ye ars. A lways use new b rake fluid
which confo rms to Fede ral Motor Vehicle
S tanda rd "FMVSS 116 DO T 4".
The brake flu id reservoir can be difficult to
r each, therefo re , we recommend that yo u
have the brake fl uid changed by yo ur au tho r­
i z ed
Audi dealer . Your dealer has the co rrec t tools, the
right brake flu id and t he know -how
to do this for you.
A WARNING
'-
- Brake flu id is poisonous. It must be stor-
ed only in the closed or igina l container
out of the reach of children!
- Brake failure can res ult from o ld or inap­
propriate brake f lu id. Observe these pre­
cautions:
- Use only brake f luid that meets SA E
spe cifi cat ion
J 17 03 and conforms to
Federa l Motor Vehi cle Standard 1 16.
Always chec k with yo ur authorized A udi
dealer to make sure yo u are using the
correct brake fluid. The cor rect type of
brake flu id is also ind icated on the
brake f lu id reservoir.
- The brake fluid must be new. Heavy use
of the brakes can cause a vapor lock if
the brake fluid is left i n the system too
long . This can se riously affect the effi­
c iency of the brakes as well as your
safety . T his could result in an accident.
W Note
Brake fluid will damage the pai nt of you r
vehicle .
@ For the sake of the environment
Because of the prob lem of proper disposal
of brake fluid as well as the spec ial too ls
r equired and the necessary expertise, we
r ecommend that yo u have the brake flu id
changed by yo ur autho rized Aud i dea le r.
Battery
General information
U nder normal operat ing cond itions, the bat­
te ry in your Audi does not need any ma inte­
nance. With
high outside temperatu res or
long da ily drives we recommend that you have
the e lectrolyte leve l che cked by an autho riz ed
A udi dealer or qu alified workshop. The elec­
tro ly t e level should also be checked e ach time
the battery is charged
¢ page 225. ...

Have the battery checked when you take your
vehicle in for service. Yo u are well advised to
replace a battery that is older than 5 years.
W ith certa in types o f airbag deployment, the
battery is disconnec ted from the vehicle elec ­
trica l system for safety reasons
c::> &. in Re­
pair, care and disposal of the airbags on
page 154.
Di sconn ecting the battery t erminal s
Some vehicle functions (power w indow regu­
l ators, for example) are lost if the battery ter­
minals are disconnected . These functions have
to be re learned after the battery terminals are
connec ted again. To prevent this, the battery
should only be disconnected from the vehicle
e lectrical system when absolutely necessary
for repairs .
Vehicl es not driven for long p eriod s
If you do not drive your vehicle over a period
of several days or weeks, electrical compo­
nents are gradually cu t back or switched off .
This reduces energy consumption and main ­
tains starting capability over a longer per iod
c::> page 185.
Some of the conven ience functions may not
operate, such as the inter ior lights or the
power seat adjustment. The conven ience
functions will be ava ilable again whe n you
turn on the ignition and sta rt the eng ine.
Winter operation
During the winter months, battery capacity
tends to decrease as temperatures drop . This
i s because more powe r is also consumed while
start ing , and the head lights, rea r window de­
fogger, etc., are used more often .
Avo id unnecessary power consumption, par­
ticularly in c ity t raffic or when t rave ling on ly
short d istances. Let you r authorized Audi
dea le r che ck t he capacity of the vehicle bat­
t ery before w inte r sets in

Because technical changes may be made to
ve hicle equipment during the model year, al­
ways compare the tire size designation on the
tire pressure labe l on your vehicle w ith the
tires on your vehicle. Make sure that the tire
size information on the veh icle label is the
same as the size of the tires on the vehicle.
This is especially important if the vehicle be­
lo ngs to someone else or you bought the veh i- cle
with different rims/tires or you bought the
vehicle as a previously owned vehicle.
Remember, your safety and that of your pas ­
sengers also depends on making sure that
l oad lim its are not exceeded. Vehicle load in­
cludes everybody and everything in and on the
vehicle. These load limits are techn ically refer­
red to as the veh icle's Gross Vehicle Weight
Rating ("GVWR"). The Gross Axle Weight Rat­
ing ("GAWR") is the maximum load that can
be applied at eac h of the vehicle's two axles .

Using the ABS sensors, the tire pressure moni ­
tor ing system compares the tire tread circum­
ference and vibration characteristics of the in­
dividual tires.
If the pressure decreases in one
or mo re tires, this is indicated in the instru­
ment cluster with a
[I] warning symbol and a
message
r:!> fig. 187 . The driver message in the
display goes out after S seconds. The driver
message can be displayed again by pressing
the
! SET ! button. If only one tire is affected,
the display will indicate its position.
The tire press ure monitoring system must be
reset via radio or MMI* each time the pres­
sures are adjusted (e. g . when switching be­
tween partial and full load pressure) or after
changing or replacing a tire on your veh icle
r:!> page 247 . The TPMS indicator only moni­
tors the tire pressure that you have prev iously
stored . You can find the recommended tire
pressures for your vehicle on the label on driv­
er's side 8-pillar

A WARNING
-
- If the tire pressure ind icator appears in
the instrument cluster display, one or
more of your t ires is sign ificantly under­
inflated . Reduce yo ur speed immediately
and avoid any hard steering or braking
maneuvers. Stop as soon as possible and
check the tires and their pressures. In­
f la te the tire pressure to the prope r pres­
sure as indicated on the vehicle's tire
pressure label
r:!> page 231. Driving on a
significantly under-inflated tire causes
the t ire to overheat and can lead to tire
fa ilure . Under -inflation also is likely to
impair the vehicle's handling and stop­ ping ability.
- The driver is responsible for maintaining
the co rrect tire pressures. You must
check the tire pressures regularly.
