196 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.
(D 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 conv ert er) is function
ing properly to ensure that your vehicle is run
ning in on env ironm entally sound manner.
,,. Always use lead-free gaso line Q page 209,
Fuel supply .
,,. Never run the tank down a ll th e way to emp
ty.
,,. Never put too much moto r oil in your engine
Q page 219, "t':::r. Adding engine oil .
,,. Never try to push -or tow -start your ve hicle .
T he cata lytic converter is an eff ic ient "clean
up" device built in to 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 exclus
ive use of unleaded f uel is critica lly
important for the life of the catalytic conv ert
er and p roper funct ion ing of the eng ine .
A WARNING
=
-The temperature of the exhaust system
is high, both when driving and after stop
p ing the eng ine .
- Never touch the exhaust tail pipes once
they have become hot. This could result
in burns.
- Do not park or operate the vehicle i n
areas where the hot exhaust system may
come in co ntact with dry grass, brush,
fue l 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 he at s hields. Dur ing driv ing, the
substance used fo r undercoating could
overheat and cause a fire.
CI) Note
- Be aware tha t just o ne tank filling with
leaded fu el w ill alre ady ser io usly de
grade the performance of the cata lytic
converter .
- Do not exceed the cor rect engine oil level
Q poge 219.
-Do not drive until the fuel t ank becomes
comple tely empty . The engine cou ld mis
fire . Unburned fuel could also get into
the exhaust system and th is co uld cause
the catalytic converter to overheat.
- Do not turn off the ignition while the ve
hicle is mov ing.
- Do not contin ue to ope rate your veh icle
under these conditions, as otherwise fuel
can reach the catalyt ic converter. Th is
co uld result in overheating of the con
verter, requir ing its replacement.
- To assure efficient operation of the Emis -
sion Control System: .,..
-To reduce the r isk of being burned, never
open the hood if you see or hear steam
or coolant escaping from the engine
compartment . Wait until no steam or
coolant can be seen or heard before ca re
fully opening the hood .
- Keep children away from the engine com
partment.
- Never spill flu ids on hot engine compo
nents. They can cause a fire .
- Never touch the radiator fan. The aux ili
ary e lectr ic fan is temperature controlled
and can switch on suddenly .
- Never open the coolant reservoir cap
when the eng ine is still warm . The cool
ant system is pressur ized and hot coo l
ant could spray out.
- Protect your face, hands and arm from
steam or hot eng ine coolant by placing a
thic k rag over the cap when you open the
coolant reservoir.
- Do not remove the engine cover under
any c ircumstances. Th is increases the
risk of bu rns.
- If wo rk on the fuel system or the electri
cal sys tem is ne cessary:
- Always disconnect the battery.
- Never smoke or work near heaters or
open flames . Fluids in the engine com
partment co uld start a fire.
- Keep an approved fire extinguisher im
mediately ava ilable.
- To avoid electrical s hock and persona l in
jury while the engine is running or being
started, never touch:
- Ignition cables
- Other components of the high voltage
electronic ignition system.
- If you must perform a check or repa ir
with the engine running:
- Fir st, fully apply the parking brake,
move se lector lever of a utomatic trans-

mission to "P" (Park); put manual
transmission in Neutral.
- Always use extreme caution to prevent
clothing, jewe lry, or long hair from get
ting caught in the radiator fan, V-be lts
or other moving parts, or from contact i ng hot parts . Tie back hair before
starting, and do not wear clothing that
will hang o r droop into the engine .
- Minimize exposure to emission and
chemical hazards~&. .

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
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 specially conditioned water and the
manufacturer's glycol-based coolant addi-
tive G13 antifreeze with anticorros ion addi
tives (50% for USA models; 60% for Canadian
models) . This mixture both assures the neces
sary frost protection and protects metal com
ponents in the engine's cooling system from
corrosion and scaling.
It also raises the boil
ing 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 antifree ze protection and cooling efficien
cy. If the coolant frost protection is too low,
the coolant could freeze and damage the vehi
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.
I f you must add coo lant, use a mixture of wa
ter and coolant addit ive. Mixing the coolant
additive with distilled water is recommended.
& WARNING
Before you check anything in the engine
compartment, always read and heed all
WARNINGS
c::;, .&. in Working in the engine
compartment on page 214.
(D Note
- Before winter sets in, have the coolant
checked to see if the coolant additive in
Checkin g and fillin g 221
your vehicle is sufficient to meet the cli
mate conditions. This is especia lly impor
tant if you live in a region where the win
ter is extremely co ld. 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 G12++ or G13 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 cause 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.
Adding 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 Veh icle
Limited Warranty.
Checking the engine coolant level
The engine coolant level can be checked with
a quick glance.

ant expansion tank
i=> fig . 185, c::;, page 216,
fig . 182. With a cold engine, the coolant Iii>
222 Check ing and filling
level should be between the "MIN" and
"MAX" markings. 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
c:> page 216.
To obtain an accurate reading, the engine must be switched
off.
The expansion tank in you r vehicle is equipped
with an e lectric coolant level sensor.
When the coolant level is too low, the warning light in the Auto-Check System
c:> page 17will
b link until you add coo lant and the level has
been restored to no rma l. Even though there is
an electric coolant level sensor, we still rec
ommend you check the coolant 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
ing system should be inspected immediately
by your authorized A udi dealer.
It is not
enough merely to add coolant.
I n a sealed system, losses can occur only if
the boiling point of the coolant is exceeded as
a result of overheat ing.
A WARNING
The cooling system is unde r pressure and
can get very hot. Reduce the risk of scald
ing from hot coolant by following these
steps .
- Turn
off the engine and allow it to cool
dow n.
- 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 very carefully in
a counter-clockwise direction wh ile ap
plying light, downward pressure on the
top of the cap .
- To avoid be ing burned, do not spill ant i
freeze or coolant on the exhaust system
'
or hot engine parts. Under certa in cond i
tions, the ethylene glycol in engine coo l
ant can catch fire.
(D Note
Do not a dd any type of radiator leak sea l
ant to your veh icle's engine coolant. Add
i ng radiator repa ir fl uid may adverse ly af
fect the funct ion and performance of your
cooling system and could result in damage
not covered by your New Veh icle L imited
War ranty .
