a reason to change the oil more often than recommended.
A WARNING
Stop! Before working in the engine com­
partme nt, always read and heed all WARN­
INGS
q & in Working in the engine com­
partment on page 258.
The engine com­
partme nt of any motor veh icle is a poten­
tially dangerous a rea and can cause ser i­
ous pe rsonal injury.
A WARNING
If you must change t he engine o il i n your
vehicle:
- Always wea r eye p rotection.
- To reduce the r isk of burns from hot en-
gine oil let the engine cool down to the
t ouch.
- When removing the oil drain plug with
yo ur finge rs, stay as far away as possible.
Always kee p your forea rm pa ra llel to the
ground to he lp prevent ho t oi l from r un­
ning down your arm.
- Drain the o il into a co nt ainer designed
f or this p urpose, one large enough to
hold at least the total amount of oil in
yo ur engine .
- T o reduce the r is k of po ison ing, never use
empty food or beverage containers that
might mis lead someone into dr inking
from them.
- Engine oil is poisono us. Keep it well out
of the reach of chi ldren.
- Cont in u ous contact with used engi ne oil
is harmful to your skin. Always protect
yo ur sk in by washing tho ro ughly with
soap and water.
(D Note
Never mix oi l ad dit ives with your engine
oil. These additives can damage your en ­
gine and adverse ly affect your Audi Limit­
ed New Vehicle Warranty.

@) For the sake of the environment
-Before changing the oil, first make sure
you know where you can prope rly dispose
of the old o il.
- Always dispose of used oil p ro perly. Nev­
er dump it on garden soil, in wooded
areas, into streams or down sewage
dra ins.
- Recycle used o il by tak ing it to a used en ­
gine oil collection facility in your area, or
contact a service station.
- We strongly recommend that yo u have
your oil cha nged by an authorized Audi
dealer or a qualified wo rkshop with the
special tools a nd expert ise required, and
proper m eans of disposa l.
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 ­
INGS c:> A in Working in the engine compart ­
ment on page 258 .

recommend us ing on ly coo lant additive G12+
+, G 13 or in an eme rgency G12 +. Do
not use a
different additive. In an emergency use pla in
water until you can ge t the co rrect addi tive
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
n ew engine coolant when refilling .
Do not f ill coolant above the "MAX" mark. Ex­
cess coola nt 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 ve ry hot. Reduce the risk of
scalding from hot coolan t by following
these steps.
- Turn off the engine and allow it to coo l

After using the inflatable spare wheel
The inflatable spare tire can be re-used as
long as it is not damaged and is not worn
down to the tread wear indicators~.&. .
When you let the air out of the inflatable
spare tire, it does not assume its folded shape
again for several hours. Until then, it cannot
be placed back in the spare wheel well and
stowed securely.
A WARNING
- Never use the spare tire if it is damaged
or if it is worn down to the tread wear in­
dicators.
- If the inflatable spare tire is more than 6
years old, use it only in an emergency
and with extreme caution and careful
driving .
- The inflatable spare tire is intended only
for temporary and short-term use .
It
should be replaced as soon as possible
with the normal wheel and tire.
- The tire pressure value for the inflatable
spare tire is located on the driver's side
8-pillar
~ page 2 78, fig . 238.
-Maximum permissible speed is 50 mph
(80 km/h).
- Avoid full-throttle acceleration, heavy
braking, and fast cornering.
- When the air is let out of the inflatable
spare wheel, it does not assume its fold­
ed shape for several hours . Until then, it
cannot be placed back in the spare wheel
well and stowed securely.
- Never drive with more than one inflata­
ble spare tire.
- For technical reasons, the use of tire
chains on the inflatable spare tire is not
permitted. If it is necessary to drive with
tire chains, the inflatable spare wheel
must be mounted on the front axle in the
event of a flat in a rear tire. The newly
available front wheel must then be in­
stalled in place of the rear wheel with
What do I do now? 297
the flat tire. Installing the tire chain be­
fore mounting the wheel and tire is rec­
ommended.
- Loose items in the passenger compart­
ment can cause serious personal injury
during hard braking or in an accident.
Never store the inflatable spare tire or
jack and tools in the passenger compart­
ment.
(D Note
- The inflatable spare tire has been devel­
oped specifically for this vehicle model.
It must not be exchanged or used for
other vehicle models. Similarly, inflata­
ble tires from other vehicle models must
not be used.
- Normal summer or winter tires must not
be installed on the inflatable tire rim.
