188 Driving and en vironm ent
8_ WARNING
After driving through water, mud, slush,
etc ., the brakes may be slow to take effect
because of wet brake rotors and pads. Dry
the brakes first by braking carefully to re
store the full braking effect.
CD Note
Vehicle components such as the engine,
transmiss ion, suspension or electrical sys
tem can be severely damaged by driving
through wate r.
@ Tips
- Check the depth of the water before dr iv
i ng through it.
- Do not stop the veh icle, dr ive in reverse
or switc h the engine off when driving
t hr ough water.
- Keep in mind that oncoming vehicles
may c reate waves that raise the water
l evel and make it too deep fo r you r vehi
cle to dr ive through safely.
-
- Avoid dr iving thro ugh salt water because
i t can ca use corrosion.
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 on environmentally sound manner.
,,. Always use lead-free gasoli ne¢ page 207,
Fuel supply .
,,. Never run the tank down a ll the way to
empty.
,,. Never put too much motor oil in your en-
gine ¢
page 217, "t':::r. Adding engine oil.
,,. Never t ry to push- o r tow-start your veh icle.
The catalytic converter is an effic ient "clean
up" device built into the exhaust system of
the vehicle. The catalytic converter burns
many of the polluta nts in the exhaust gas be
fore they are released into the atmosphe re. The exclusive
use of unleaded f uel is critica lly
important for the life of the catalytic convert
er and proper funct ion ing of the eng ine .
A WARNING
= -
-Do not park or operate the vehicle in
areas where the hot exhaust system may
come in co ntact with dry grass, brush,
fuel spill or other material wh ich can
cause a fire .
- Do not app ly additional undercoating or
r u stp roofing on or nea r the exhaust
manifold, exhaust pipes, cataly tic con
ver ter or heat shields. Dur ing driv ing, the
substance used for under coa ting co uld

Engine cooling system
Coolant
The engine coolant performs two functions: it
keeps the engine from overheating and it pro
te cts the engine from freezing in the winter .
The cooling system is sealed and generally re
qu ires 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 G 13 antifreeze with
anticor ros ion add itives (50% for USA mode ls;
60% for Canadian mode ls). This mixtu re both
assures the ne cessa ry frost prote cti on and
p rotec ts metal components in the engine's
coo ling system from cor ros io n an d scaling. It
a lso raises the boiling point of the coolant.
D o not red uce the con cent ration o f th e coo l
ant in the summe r by adding plain water .
The
proportion of coolant additive must be at least 50% but not more than 60%
to ma in
tain antifreeze protection and cooling efficien
cy. If the coolant frost protect ion is too low,
the coolant cou ld freeze and damage the veh i
cle heating and eng ine cooling system .
For yea r-round driving, antifreeze is added at
the factory for temperatures down to:
- -3 1 °F (-35°C)USA
- -4 0 ° F ( - 40 °C) Canada.
A WARNING
Before yo u check any thing in the engine
compartment, always read and hee d all
W AR NIN GS
¢ .&. in Working in the engine
compartment on page 212.
(D Note
- Before win ter se ts in, have the coolan t
checked to see if t he coolant ad dit ive i n
your vehicle is suffic ient to meet the cli
mate cond itions . T hi s is especially imp or
tant if you live in a regi on whe re the w in
te r is e xtremely cold. If necessary, in -
Checking and fillin g 219
crease the propo rtion of coo lant add itive
to 60%.
- When adding coolant additive to yo ur
coolin g system , remembe r:
- We reco mmend us ing o nly coola nt ad
d itive G12++ or G13 for your vehicle .
This coolan t ad ditive is availab le at a u
thor ized Audi dealers. O ther types of
ant ifree ze can s ignific antly red uce cor

"' Park yo ur vehicle on a lev el su rface .
"' Turn off the ignition .
"' Read t he e ngine coolant level from the
coo lant expan sio n ta nk ¢
fig. 178 ,
¢ fig. 175. With a cold engine, the coolant
level sho uld be between the "MIN " and
"MAX" markings . When the engine is warm,
the level may be slightly above the "MAX"
marking.
Iii>
220 Check ing and filling
The location of the coolant expansion tank
can be seen in the engine compartment illus
tration ¢
page 214 .
To obtain an accurate read ing, the eng ine
must be switched off .
The expans io n tank in you r vehicle is equipped
with an e lectr ic cool ant level sensor.
When the coolant level is too low, the warning light in the A uto-Check System ¢
page 18 will
b link until you add coo lant and the level has
been restored to no rm al. Even though the re is
an e lec tric coolant level sensor, we s till rec
ommend you check the coolant leve l from
time to time.
Coolant loss
Coolant loss may indicate a leak in the cooling
system. In the event of coolan t loss, the cool
i ng system should be inspected immedia tely
by your authorized A udi dealer. It is not
enough merely to add coolant.
I n a
s e aled system, losses can occur only if
the boiling poin t of the coolant is excee ded as
a result of overheating.
A WARNING
The cooling system is unde r pressure and
can get ve ry hot. Reduce the risk of sca ld
ing from hot coolant by following these
steps.
- Turn off the engine and allow it to cool
down.
- Protect yo ur face, hands and arms from
escaping fluid and steam by covering the
cap with a large, thick rag.
- Turn the cap slowly and ve ry carefu lly in
a counter-clockwise direction wh ile ap
plying light, downward pressure on the
top of the cap .
- To avoid being b urned, do not spill ant i
freeze or coolant on t he exhaust system
or hot eng ine parts. Unde r certain condi
tions, t he ethy lene g lycol in engine cool
an t can ca tch fire.
(D Note
Do not ad d any type of radiator leak sea l
ant to your veh icle's engine coo lant. Add
i ng radiator repa ir fluid may adverse ly af
fect the funct ion and performance of your
cooling system and could result in damage not cove red by your New Veh icle L imited
War ran ty .
