your speed and the distance between
your vehicle and other vehicles.
- For reasons of safety, cruise control
should not be used in the city, in stop­
and-go traffic, on twisting roads and
when road conditions are poor (such as
ice, fog, gravel, heavy rain and hydro­
plan ing) -you could have an accident.
- Switch the cruise control off temporarily
when dr iv ing in turning lanes, highway
exits or in construction zones.
- Please note that unconsciously "resting"
your foot on the accelerator pedal causes
cru ise contro l not to brake. This is due to
the control system being overridden by
the driver's acceleration.
- Never use the cruise control when driving
off-road or on unpaved roads. The cruise
con tro l is intended for use only when the
vehicle is being operated on paved roads,
and is not suitable for use off-road or on
unpaved roads.
- If a brake system malfunction such as
overheating occurs when the cruise con ­
trol system is switched on, the braking
function in the system may be switched off. The other cruise control functions re­
main active as long as the indicator light

206 Driving and en vir onm ent
Catalytic converter
It is very important that your emission con­
trol system (catalytic converter) is function­
ing properly to ensure that your vehicle is run­
ning in an environmentally sound manner .
• Always use lead-free gasoline¢ page 228,
Fuel supply.
• Never run the tank down all the way to
empty .
• Never put too much motor oil in your en-
gine ¢
page 238, Adding engine oil~-
., Never try to push- or tow -start your veh icle.
The catalytic converter is an eff ic ient "clean­
up" device built into the exhaust system of
the vehicle. The catalytic converter burns many of the pollutants in the exhaust gas be­
fore they are released into the atmosphere.
The exclusive use of unleaded fuel is critically
important for the life of the cata lytic conve rt­
e r and proper functioning of the engine.
& WARNING
-
- Do not park o r operate the vehicle in
areas where the hot exhaust system may
come in contact with dry grass, brush,
fuel spill or other material which can cause a fire.
- Do not apply additional undercoating or
rustproofing on or near the exhaust
man ifold, exhaust p ipes, catalytic con­
verter or heat shields . During driving, the
substance used for undercoating could
overheat and cause a fire .
@ Note
-Be aware that just one tank filling with
leaded fuel will already seriously de­
grade the performance of the catalytic
conve rter .
- Do not exceed the correct engine oil level
¢ page 238.
-Do not drive until the fuel tank becomes
completely empty. The eng ine could mis­
fire . U nburned f uel could a lso get into the exhaust system and this co
uld cause
the cata lytic converter to overheat .
- Do not turn off the ignition while the ve ­
hicle is moving.
- Do not continue to ope rate your veh icle
under these conditions, as otherwise fuel
can reach the catalytic converter. This
cou ld result in overheating of the con­
verter, requir ing its replacement.
- To assure efficient operation of the Emis ­
sion Control System:
- H ave your vehicle maintained properly
and in accordance w it h the service rec­
ommendat ions in your Warranty &
M ain tenance book let.
- L ack of prope r maintenance as we ll as
improper use of the vehi cle will impair
the function of the em iss ion contro l
system and could lead to damage .
@ For the sake of the environment
Even when the Emiss ion Control System is
operat ing proper ly, the exha ust gas can
have a sul fur -li ke exhaust gas smell under
some operating states . This depends on
the sulfur content of the fuel being used .
Using a different brand of fue l may help,
or f il li ng the tank with lead-free super
grade gasoline .
Avoid damaging the
vehicle
When you are d rivi ng on poor roads, or over
c u rbs, steep ramps, etc., ma ke certai n that
low- ly ing parts s uch as spoilers and exha ust
system parts do not bottom o ut and get dam ­
aged.
T his is espe cially true for ve hicles with low­
s lung chassis (spor ts chassis)* and fully load­
ed vehicles .

240 Checking 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 anticorros ion add itives (SO% for USA
models; 60% for Canadian models). This mix­
ture both assures 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 of the coo l­
ant in the summer by adding plain water .
The
proportion of coolant additive must be at
least 50% but not more than 60%
to main­
tain antifreeze protection and cooling efficien­
cy. If the coolant frost protection is too low,
the coolant could freeze and damage the veh i­
cle heating and engine cooling system .
For year-round driving, antifreeze is added at
the factory for temperatures down to:
- - 31 °F ( - 35°() USA
- - 40°F ( - 40°() Canada .
A WARNING
Before you check anything in the engine
compartment, always read and heed all
WARNINGS
c:> &. in Working in the engine
compartment on page 233.
- Before winter sets in, have the coolant
checked to see if the coolant addit ive in
your vehicle is sufficient to meet the cli­
mate cond itions. This 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 coolant additive
to 60%.
- When adding coolant additive to your
cooling system, remember:
- We recommend using only coolant ad­
ditive Gl2++ or Gl3 for your vehicle.
This coolant additive is available at au­
thorized Audi dealers. Other types of
antifreeze can significantly reduce cor­
rosion protection. The resulting corro ­
sion can ca use a loss of coolant and se­
rious engine damage.
- Do not add any type of radiator leak seal ­
ant to your vehicle's engine coolant .
Add ing radiator repair fluid may adverse­
ly affect the function and performance of
your cooling system and could result in
damage not covered by your New Vehicle
Limited Warranty.
Checking the engine coolant level
The engine coolant level can be checked with
a quick glance .
Fig. 199 Engine compartment : cover on t he coolant
expansion tank
Before you check anyth ing in the engine com­
partment,
always read and heed all WARN­
INGS c:> &. in Working in the engine compart­
ment on page 233 .
.. Park your vehicle on a level surface .
.. Turn off the ignition .
.. Read the engine coolant level from the
coolant expansion tank
c:> fig. 199,
c:> page 235, fig. 196 . 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 illus­
tration ¢
page 235.
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 30 will
blink until you add coolant and the level has
been restored to normal. Even though there is
an electric coolant level sensor, we still rec­
ommend 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 cool­
ing system should be inspected immediately
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.
(D Note
Do not add any type of radiator leak seal­
ant to your vehicle's engine coolant. Add­
ing radiator repair fluid may adversely af­
fect the function 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 com­
partment,
always read and heed all WARN­
INGS ¢ A in Working in the engine compart­
ment on page 233.
... Turn off the engine .
... Let the engine cool down.
Checking and filling 241
... Place a thick rag over the coolant expansion
tank ¢
page 240, fig. 199 and carefully turn
the cap counter-clockwise ¢
A.
... Add coolant.
... Twist the cap on again
tightly.
Replacement engine coolant must conform to
exact specifications ¢
page 240, Coolant. We
recommend using only coolant additive
Gl2+
+, Gl3
or in an emergency Gl2 +. Do not use a
different additive . In an emergency use plain
water until you can get the correct additive and can restore the correct ratio. This should
be done as soon as possible .
If you have lost a considerable amount of
coolant, then you should add cold antifreeze
and cold water only when the engine is cold.
Always use
new engine coolant when refilling.
Do not fill coolant above the "MAX" mark. Ex­
cess coolant will be forced out through the
pressure relief valve in the cap when the en­
gine becomes hot.
A 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.
- 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 an­
tifreeze or coolant on the exhaust sys­
tem or hot engine parts. Under certain
conditions, the ethylene glycol in en­
gine coolant can catch fire.
-Antifreeze is poisonous. Always store an­
tifreeze in its original container and well
out of the reach of children.
