off the eng ine until 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.

General information
Applies to vehicles: with Homelink® unive rsal remote
co ntrol
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 moto r signals. Programming the in­
d iv idual remote control fo r you r 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 required by federal safety stand­
ards. This includes any garage door open­
er mode l manufact ured 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 s tandards. Us ing a garage doo r
o pener witho ut these fea tures increases
risk of serious inj ury or death.
- F or safety reasons never release t he
parking brake or s tart the engine while
anyone is standing in front of the vehicle .
- A garage door or an est ate 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 electrica l 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 rang e of motion of any
equ ipme nt being ope rated.

Engine compartment
Be especially careful when cleaning the en­
gine compartment.
A lw ays s witch off the ign ition befor e clean ­
ing the eng in e
c:> & .
Plenum panel
Remove leaves from the plenum pane l in front
of the windshield under the engine compart­
ment. This prevents the water drain ho les
from becoming blocked, and it prevents de­
bris from entering the veh icle inter ior through
the heating and ventilation ducts .
Corro sion protecti on
The engine compartment and transmission
have been corrosion-protected at the factory.
Good anti-corrosion treatment is very impor ­
tant, particular ly in the winter . If the vehicle
is frequent ly driven on salt treated roads, the
entire engine compartment and plenum panel
should be thoroughly cleaned at the end of
winter and retreated to prevent sa lt damage.
At the same time, the underside of the vehicle
should be washed as we ll.
If the engine compartment is cleaned at any
time with grease removing solut ions
1>, or if
you have the engine washed, the anti-corro­
sion treatment is a lmost always removed as
well.
It is therefore essential to have a long­
lasting co rrosion protection reapp lied to a ll
surfaces, seams, joints and components in the
engine compartment.
A WARNING
Be aware: The engine compa rtment of any
motor vehicle is a potentially hazardous
area.
- Before working in the engine compart­
ment, be s ure to read the in format ion
c:> page 225.
- Before reaching into the front pane l, al­
ways switch off the ignition. Otherwise,

(D Note
When adding flu ids, always make sure that
they are poured into the proper conta iner
or f iller opening, otherwise serious dam­
age to vehicle systems w ill occur.
® For the sake of the environment
To detect leaks in time, inspect the vehicle
floor pan from underneath regularly. If
you see spots from oil or other ve hicle flu­
i ds, have yo ur vehicle inspected by a n au­
thori zed Audi dea le r.
Closing the engine hood
.,. Pull the hood down un til the pressure from
t he struts is reduced.
.,. Let the hood drop down and latch in p lace .
Do not try to push it shut; it may fail to en­
gage ¢&_ .
A WARNING
-
A hood that is not completely latched
could fly up and b lock your view while dr iv­
ing.
- When you close the engine hood, check it
to make sure the safety catch has p roper­
ly engaged. The hood sho uld be flush
with the surrou nding vehicle body pa rts.
- If you notice while driv ing t hat the hood
is not s ecured prope rly, stop at onc e and
close it.

232 Check ing and filling
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 sealed and generally re­
quires little attention.
The cooling system has been filled at the fac­
tory with a permanent coolant which does not need to be changed. The coolant consists of a
mixture of water and the manufacturer's gly ­
col-based coolant additive Gl3 ant ifreeze
with ant icorros ion add itives (50% for USA
models; 60% for Canad ian models). This mix­
ture both assu res the necessary frost protec­
tion and protects metal components in the
engine's cooling system from corrosion and
scaling. It also raises the boiling point of the
coolant.
Do not reduce the concentration o f the coo l­
ant in the summer by adding plain water .
The
propo rtion of coolant add it iv e mu st be at
l eas t 50 % but not mo re than 6 0%
to main­
tain antifree ze protection and cooling efficien­
cy. If the coolant frost protect ion is too low,
the coolant could freeze and damage the veh i­
cle heating and eng ine cooling system .
For year-round driving, antifree ze is added at
the factory for temperatures down to:
- -31°F(-35°C)USA
- - 40 ° F ( -40 °C) Canada.
A WARNING
Before yo u check anything in the engine
compartment, always read and heed all
WARNINGS
c:> &. in Working in the engine
compartment on page 225.
- Before winter sets in, have the coolant
checked to see if the coo lant addit ive in
your vehicle is suffic ient to meet the cli­
mate cond itions. Th is is especially impor­
tant if you live in a region where the w in- ter is extreme
ly cold . If necessary, in ­
crease the proportion of coo lant additive
to 60%.
- When adding coolant additive to your
cooling system, remember:
- We recommend us ing only coolant ad­
d itive Gl2++ or G l3 (check the labe l)
fo r your vehicle. This coolant additive is
ava ilable at a utho rized Aud i dea le rs.
Other types of antifreeze can sign ifi­
cantly reduce corros ion protection. The
res ulting corrosion can cause a loss of
coolant and serious engine damage.
- Do not add any type of radiator leak seal ­
ant to yo ur vehicle's engine coolant .
Add ing radiator repair flu id may adverse­
ly affect the function and performance of
your cooling system and could resu lt in
damage not covered by your New Veh icle
Limited War ranty.
Checking the engine coolant level
The engine coolant level can be checked with
a quick glance .
