-L Engine cooling system malfunction
A malfunction in the engine cooling system
must be repaired as soon as possible.
• Switch off engine and check coolant level
If the indicator light turns on and the mes ­
sage appears, the coo lant temperature is too
high or the coo lant level is too low.
.. Pull
off the road.
.. Stop the vehicle .
.. Turn
off the engine.
.. Check coolant level
c> page 235.
.,. Add coolant if necessary c> page 235 .
.. Continue driving only after the eng ine cool­
ant warn ing/ indicator light goes out .
.. Contact your authorized Audi dealer for as-
sistance if necessary .
If the engine coolant level is correct, then the
radiator fan may be the cause of the malfunc­
tion .
• Coolant temperature too high! Please let
engine run with vehicle stationary
If the indicator light turns on and the mes­
sage appears in trailer mode*, let the engine
run at idle for a few m inutes to cool down.
A WARNING
- If your veh icle should break down for
mechanical or other reasons, park at a
safe distance from moving traffic, turn
off the engine and turn on the hazard
warning lights¢
page 45, Emergency
flasher.
- Never open the hood if you see or hear
steam or coolant escaping from the en­
gine compartment -you risk being scald­
ed. Wait until you can no longer see or
hear steam or coo lant escaping .
- The engine compartment of any vehicle
is a dangerous area. Before you perform
any work in the engine compartment,
turn of the eng ine and allow it to cool.
Follow the warning stickers¢
page 227.
@ Note
Do not continue driving if the . symbol
ill uminates . There is a malfunction in the
engine cooling system -you could damage
your engine.
D Battery
This warning/indicator light detects a mal­
function in the generator or in the vehicle 's
electrical system .
The .warn ing/ indicator light illuminates
when you switch on the ignition and must go
out after the eng ine has started .
• Alternato r fault : Battery is not being
charged
If t he indicator light turns on and the mes­
sage appears, there is a malfunction in the
generator or vehicle electrical system .
Drive to your authorized Audi dealer or quali­
fied workshop immed iate ly. Because the vehi­
cle battery is discharging, turn off all unnec ­
essary e lectrical equipment such as the radio.
Seek professiona l assistance if the battery
charge level is too low.
(•) Low battery: battery will be charged
while driving
If the indicator light turns on and the mes­
sage appears, there may be limited starting
ability .

S top-Sys tem.
A WARNING
- Never allow the engine to run in confined
spaces -danger of asphyxiation .
- Never turn off the eng ine unti l the vehi­
cle has come to a complete stop .
- The brake booster and power steer ing
only work when the engine is running . If
the engine is off, you have to use more
force when steering or braking. Because
you cannot stee r and brake as you usua l­
ly wou ld, this could lead to crashes and
serious injur ies.
- Avoid high engine rpm, fu ll throttle and
heavy engine loads unti l the engine has
reached operating temperature - ot her­
wise yo u risk eng ine dam age.
- The eng ine cannot be started by pushing
or tow ing the veh icle.
(D Tips
- After a cold engine is started, there may
be a brief period of increased noise be ­
cause oil press ure must fi rst bu ild up in
the hydraulic valve adjusters. This is nor ­
mal and not a ca use for concern .
-If yo u leave the vehicle with the ignit ion
switched on, the ignition will switch off

Homelink
Universal remote
control
General information
Applies to vehicles: with Homelink u nive rsal remote con­
tro l
The HomeLink universal remote control can
be programmed with hand-held transmitters
from existing equipment.
With Homelink, you can control devices such
as the garage door, security systems, house
lights, etc. comfortably from the inside of you
vehicle.
Homelink makes it possible for you to replace
three different remote controls from devices in your home with one universal remote . Th is
feature works for most garage door and exte­
rior door motor signals. Programming the in­
d iv idual remo te control fo r your remote con ­
trol takes p lace near the center of the radiator
grille. There is a control module attached at
this location .
A one-t ime programm ing of the sensor mus t
be performed before you are able to use sys­
tems w ith Homelink.
A WARNING
- Never use the Homelink transmitter
with any garage door opener that does
have not the safety stop and reverse fea­
ture as requ ired by federal safety stand­
ards. Th is includes any garage door open­
er model manufactured before April 1, 1982.
- A garage door opener which cannot de­
tect an object, signaling the door to stop
and reverse does not meet current feder­
al safety standards . Us ing a garage doo r
opener witho ut these fea tures increases
risk of serious injury or death.
- For safety reasons never release the
parking brake or start the engine while
anyone is standing in front of the vehicle .
- A garage door or an estate gate may
sometimes be set in motion when the Homelink remote control is being pro­
grammed. If the device is repeatedly ac­
tivated, this can overstrain motor and
damage its electrical components -an
overheated motor is a fire hazard!
- To avo id possible injuries or property
damage, please always make absolutely
certa in that no persons or objects are lo­
cated in the range of motion of any
equ ipment being operated.

is not s ecured prope rly, stop at onc e and
close it.

234 Check ing and filling
@ For the sake of the environment
- Before changing your oil , first make sure
you know where you can properly dispose
of the used o il.
- Always dispose of used engine oil proper­
l y. Do not dump it on garden soi l, wood­
ed areas, into open streams or down
sewage dra ins.
- Recycle used engine oil by taking it to a
used engine oil collection facility in your
area, or contact a service station .
Engine cooling system
Coolant
The engine coolant performs two functions: it
keeps the engine from overheating and it pro­ tects the engine from freezing in the winter.
The cooling system is sea led and generally re­
q uir es little attention .
The cooling system has been filled at the fac ­
tory with a pe rmanent coolant which does not
need to be c hanged. The coolant consists of a
mixture of spec ia lly conditioned water and the
manufacturer 's glyco l-b ased coo lant add i-
tive G l3 antifreeze with ant icorrosion addi ­
tives (50% for USA models ; 60% for Canadian
mod els). This mixture both assures the nec es­
sary frost protection and protects metal com­ ponents in the engine's cooling sys tem from
corrosion and scaling . It a lso raises the boil­
ing point of the coolant .
Do not red uce the concentration o f the coo l­
ant in the summer by adding plain water.
The
proportion of coolant add itive mu st be at
l e a st 50 % but not more than 60 %
to main­
tain antifreez e protection and cooling efficien­
cy . If the coolant frost prote ct ion is too low,
the coo lant cou ld freeze and damage the veh i­
cle hea ting and eng ine cooling system.
For yea r-round d riving, antifreeze is added at
the fac to ry for temperatures down to:
-- 31°F( -35°C)USA
- -40 °F ( -40 °C) Canada. If
you must add coolant, use a mixture o f wa ­
ter and coolant additive . Mixing the coo lant
additive with distilled water is recommended.
A WARNING
-
Before you c heck anything in the engine
compartment, always read and heed a ll
WAR NINGS
c::, & in Working in the engine
compartment on page 22
7 .
(D Note
- Before winter sets in, have the coo lant
checked to see if the coolant additive in
your vehicle is sufficient to meet the cli­ mate conditions . This is especia lly impor­
tan t if you live in a reg io n where the win­
t er is ex treme ly cold. If ne cessa ry, i n­
crease the pr opo rtion of coo lant add itive
t o 60%.
- Whe n adding coolant additive to yo ur
c oolin g sys tem, remembe r:
- We recommend using on ly coolant ad ­
d itive Gl2++ or Gl3 (check the label)
for your vehicle . This coolant additive is
ava ila ble at autho rized Aud i deale rs.
Other types of antifreeze ca n sig nifi­
ca ntly reduce co rr os io n protection. The
r es ult ing co rrosion c an c ause a los s o f
coolant and serious engine damage.
- Do not add any type of rad iator leak seal­
a n t to y our vehicle 's engine coolant.
Add ing radiator repai r fl uid may adverse ­
ly affect the function and performance of
your cooling system and co uld resu lt in
damage not covered by yo ur New Vehicle

Checking the engine coolant level
The engine coolant level can be checked with
a quick glance .
Fig. 196 Eng ine compartment: cover on the coolant
expansion tank
Before you check anything in the engine com­
partment,
alwa ys read and hee d all W ARN­
ING S ¢.&. in Working in the engine compart­
ment on page 22
7 .
.,. Park your vehicle on a level surface.
.,. Switch off the ignit ion.
.,. Read the engine coolant level from the cool­
ant expansion tank¢
fig. 196, ¢ page 229 ,
fig. 193 .
With a cold engine, the coolant
level should be between the "min" and
"max" mar kings. When the engine is warm,
the leve l may be slightly above the "max"
marking.
The location of the coolant expansion tank
can be seen in the engine compartment illus­
tration¢
page 229 .
To obtain an accurate read ing, the eng ine
must be switched off.
The expans ion tank in you r 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 17 will
illum inate u ntil you add coolant a nd the level
has been restored to normal. Even though
there is an electric coolant level sensor, we
still recommend you check the coolan t leve l
from time to time.
Coolant loss
Coolant loss may indicate a leak in the cool ing
system. In the event of coolant loss, the cool-
Checkin g and fillin g 235
ing system should be inspected immediately
by your authorized Audi dealer . It is not
enough merely to add coolant.
In a
s ea led system, losses can occur on ly if
the boiling point of the coo lant is exceeded as
a result of overheating.
A WARNING
The cooling system is under pressure and
can get very hot. Reduce the risk of scald­
ing from hot coolant by follow ing these
steps.
- Turn off the engine and allow it to cool
down.
- Protect your face, hands and arms from
escap ing f lu id and steam by cover ing the
cap with a la rge, th ick rag.
- Turn the cap slowly and very carefully in
a counter-clockwise d irect ion while ap­
plyi ng light, downward pressure on the
top of the cap .
- To avo id being burned, do not sp ill anti­
freeze or coolant on the exhaust system
or hot engine parts. Under certa in cond i­
tions, the ethylene gly col in engine coo l­
a nt can catch fire.
(D Note
Do not add any type of radiator leak sea L­
ant to your veh icle's engine coo lant . Add­
i ng radiato r repa ir flui d may adverse ly af­
fect the funct io n and performa nce o f your
cooling system and could result in damage
