Catalytic converter
Applies to vehicles: with gasoline engine
It is very important that your emission control 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 250,
Gasoline .
... Never run the tank down all the way to
empty .
... Never put too much motor oil in your en-
gine ¢
page 264, Adding engine oil~-
.,. Never try to push- or tow-start your veh icle.
The catalytic converter is an eff icient "clean
up" device built into the exhaust system of
the vehicle. The catalytic converter burns
many of the poll utants in the exhaust gas be
fore they are released into the atmosphe re.
The exclusive use of unleaded fuel is cr it ically
i mportant for the life of the cata lytic convert
e r and proper fu nctioning of the engine.
A WARNING ,~
- Do not park or operate the veh icle 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 shie lds . During driving, the
substance used for undercoating could
overheat and cause a fire.
{[) Note
-Be aware that just one tank fi lling with
le aded fuel will already seriously de
grade the performance of the catalytic
conve rter .
- Do not exceed the correct engine oil level
¢ page 264.
-Do not drive until the fuel tank becomes
completely empty. The eng ine could mis
fire . U nburned fuel could a lso get into
Dri vin g and en vironm ent 229
the exhaust system and this cou ld cause
the catalytic converter to overheat .
- Do not turn off the igni tion while the ve
hicle is moving.
- Do not con tinue to ope rate your veh icle
unde r these conditions, as othe rwise fuel
can reach the catalytic converter. This
co uld result in overheating o f the con
verter, requir ing its replacement.
- To assure efficient operation of the Emis
sion Control System:
- H ave your vehicle maintained prope rly
and in accordance w ith the se rv ice rec
ommendat ions in you r Warranty &
M ain tenance boo klet.
- L ack of prope r maintenance as we ll as
improper use of the vehi cle w il l impair
the function of the em ission contro l
system and could lead to damage .
@ For the sake of the environment
Even when the Emiss io n Control System is
operat ing properly, 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 illing the tank with lead-free super
grade gasoline .
Diesel particulate filter
Applies to vehicles : with diese l eng ine
The diesel part ic u late filter filters nearly all of
the soot particles out of the exhaust . The fil
ter cleans itself automat ica lly under normal
driv ing cond itions . If the filter ca nnot clean it
self (for example, because you a re o nly dr iving
short distances), the fi lter becomes clogged
with soot and the. symbo l for the diesel
particu late filter ill uminates ¢
page 3 7.
A WARNING
- Do not park your vehicle over flammable
materia ls such as grass or leaves because
the high temperature of the diesel par-
ticulate fi lter could start a fire. ..,. •
•
-Apply the parking brake.
- Move selector lever to "P" (Park).
- Always let the engine cool down. Hot
components will burn skin on contact.
- To reduce the risk of being burned, never
open the hood if you see or hear steam
or coolant escaping from the engine
compartment. Wa it until no steam or
coolant can be seen or heard before care
fully opening the hood.
- Keep children away from the engine com
partment .
- Never spill fluids on hot engine compo
nents. They can cause a fire.
- Never touch the radiator fan. The auxili
ary electric fan is temperature controlled
and can switch on suddenly.
- Never open the coolant reservoir cap
when the engine is still warm. The cool
ant system is pressurized and hot cool
ant could spray out .
- Protect your face, hands and arm from
steam or hot engine coolant by placing a
thick rag over the cap when you open the
coolant reservoir .
- If work on the fuel system or the electri
cal system is necessary:
- Always disconnect the battery.
- Never smoke or work near heaters or
open flames. Fluids in the engine com
partment could start a fire.
- Keep an approved fire extinguisher im
mediately available.
- To avoid electrical shock and personal 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 repair
with the engine running:
- First, fully apply the parking brake,
move selector lever to "P" (Park).
Checking and filling 259
-Always use extreme caution to prevent
clothing, jewelry, or long hair from get
ting caught in the radiator fan, V-belts
or other moving parts, or from contact ing hot parts . Tie back hair before
starting, and do not wear clothing that
will hang or droop into the engine.
- Minimize exposure to emission and
chemical hazards

Changing the engine oil
Engine oil mus t be changed at intervals listed
in the Warranty
& Maintenance booklet.
The eng ine oi l and oil fi lter m ust be changed
accord ing to the mileage and time intervals
specified in your vehicle's Warranty
& Mainte
nance booklet . Do not exceed these intervals -
harmful s ludge and depos its from old engine
o il can reduce engi ne pe rformance and can
lead to expens ive engine repa irs.
Chang ing oi l at regula r intervals is so very im
po rtant because t he lubricat ing propert ies of
o il decrease gradually du ring normal vehicle
u se.
If you are not sure when to have the oi l
c h anged, ask your a uthori zed Audi Se rvi ce A d
visor .
U nder some c ircumstances the engine oil
sho uld even be cha nged more often than

ten if you often dr ive short distances, ope rate
t h e ve hicle in dusty a reas or mostly under
stop-and-go t raff ic conditions, or when you
u se your vehicle where temperatures stay be
low free zing point for long periods.
Detergent additives in the oil will make fresh
oi l loo k dark after the engine has been run-
ning for a short time . T hi s is normal and is not
IJ,,
a reason to change the oil more often than recommended.

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.
T he cooling sys tem is sealed and genera lly re
quires little attention.
T he cooli ng system has bee n filled a t the fac
t ory with a permanent coolant which does not
need to be c hanged . The coo lant cons ists of a
mixture of water and the manufacturer's gly
col-based coo lant additive G l3 antifreeze
with anticorrosion additives (50% for USA
models; 60% for Canadian mode ls). This m ix
ture both assures the necessary frost protec
tion and protects meta l compone nts in t he
engine's cool ing system from corros io n and
sca ling.
It also raises the boiling point of the
c oolant.
Do not reduce the concentration of the cool
ant in the s ummer by adding p lai n water .
The
proportion of coolant additive must be at
lea st 50 % but not more than 60 %
to main
tai n antifree ze pro te ct io n a nd coo ling eff icien
cy .
If the coo lant fros t protection is too low,
the coo lant co uld freeze and damage the vehi-
cle heating and engine cooling system. .,..

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 Audi d ealer. It is not
enough merely to add coolant.
I n a
sea led system, losses can occur only if
the boiling point of the coolant 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 following these
steps.
- Turn off the engine and allow it to coo l
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 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
o r hot eng ine parts. Under certai n condi
t ions, the ethy lene g lycol i n engine cool
an t ca n ca tch fire.
(D Note
Do not add any type of rad iator leak seal
ant to you r vehicle's eng ine coolant. Add
ing radiator repair f luid may adversely af
fec t the function and pe rformance of your
cooling system and could res ult 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 engi ne com
partment ,
alwa ys read and heed all WARN

and can restore the correc t ratio. This sho uld
be done as soon as possible.
If you have lost a cons iderab le amount of
coolant , the n you sho uld add cold ant ifree ze
and cold wate r on ly when the engine is cold.
Always use
