A WARNING
-Always observe the warning in¢ page 191,
before open ing the hood and check ing the
engine coolant level.
- Never open the engine hood if you see or
hear steam, or if you see engine coolant
dr ipping from the engine compartment. You
cou ld burn yourself. Let the eng ine cool off
first so that you cannot hear o r see any
steam o r engine coo lant.
0 Note
- Mount ing additional lights or accesso ries in
fron t of the a ir inlets reduces the cooling ef­
fect of the radia to r. A t high outside temper­
atu res or high e ngine load, the eng ine could
overheat.
- The front spo iler has been designed to prop­
erly distribute the cooling air when the veh i­
cle is moving. If the spo iler is damaged, this
could reduce the cooling effect and the en­
gine could then overheat. Ask your author­ ized Audi dealer for assistance.
Tachometer (engine rev counter)
The tachometer indicates the engine RPM (revo­
lutions per minutes).
If engine RPM drops be low 1,5 00, you should
downshift to the next lower gea r. T he red area at
the end of the scale indicates max imum permis­
sible eng ine RPM after the break-in period . Be­
fore reachi ng this area, move the selector lever to
position D/S or ease your foot off the accelerator
pedal.
(D Note
The tachometer needle@¢ page 10, fig. 3
should o nly briefly be in the red zone: you
co uld damage your eng ine! The beginn ing of
the r ed zone varies depending on the engine.
@ For the sake of the environment
Upshift ing early saves fuel and reduces eng ine
noise .

A hood that is not comp letely latched could
fly up and block your view while driving.
- When you close the engine hood, check it to
make sure the safety catch has properly en­
gaged . The hood should be flush with the
surrounding vehicle body parts.
- If you notice while driv ing that the hood is
not secured properly, stop at once and close
it.
Working in the engine compartment
Be especially careful whenever you work in the
engine compartment.
-
Whenever you must perform any work in the
engine compartment, for example checking and
filling different fluids , there i s a risk of injury ,
burns and accidents. To prevent personal injury
always observe the following WARNINGS . The
engine compartment of any vehicle is a hazard­
ous area
c:> .&. .
A WARNING
-
To help avoid injury, before you check any-
thing under the hood:
- Turn off the engine.
- Remove the ignition key .
- Apply the parking brake.
- Move selector lever of automatic transmis-
sion to "P" (Park); put manua l transmission

Checking and Filling
-To reduce the risk of being burned, never
open the hood if you see or hear steam or
coolant escaping from the engine compart­
ment . Wait until no steam or coolant can be
seen or heard before carefully 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 auxiliary
electric fan is temperature controlled and
can switch on suddenly .
- Never open the coolant reservoir cap when
the engine is still warm. The coolant system
is pressurized and hot coolant 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 .
- Do not remove the engine cover under any
circumstances. This increases the risk of
burns.
- If work on the fuel system or the electrical
system is necessary :
- Always disconnect the battery.
- Never smoke or work near heaters or open
flames. Fluids in the engine compartment could start a fire.
- Keep an approved fire extinguisher imme­
diately available .
- To avoid electrical shock and personal injury
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 of automatic transmission
192
to "P" (Park); put manual transmission in
Neutral.
- Always use extreme caution to prevent
clothing, jewelry, or long hair from getting
caught in the radiator fan, V-belts or other
moving parts, or from contacting 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 chemi­ cal hazards
