Instrument s and warning /indicator lights 11
,&_ WARNING
- Always observe the warning in
¢ page 208, Engine compartment, be­
fore opening the hood and checking the
engine coolant level.
- Never open the engine hood if you see or
hear steam, or if you see engine coolant
dripping from the engine compartment.
You could burn yourself. Let the engine cool off first so that you cannot hear or
see any steam or engine coolant .
(D Note
-Mounting additional lights or accessories
in front of the air inlets reduces the cool­
i ng effect of the radiator. At h igh outside
temperatures or high engine load, the
engine could overheat.
- The front spo iler has been designed to
properly distribute the cooling air when
the veh icle is moving. If the spoiler is
damaged, this could reduce the cooling
effect and the engine could then over­
heat. Ask your authorized Audi dealer for
assistance.
Tachometer (engine rev counter)
The tachometer indicates the engine RPM
(revolutions per minutes).
If engine RPM d rops be low 1,500 , you should
downshift to the next lower gear. The red area
at the end of the scale indicates maximum
permissible engine RPM after the break-in pe­
riod. Before reaching this area, move these­
lector lever to position D/S or ease your foot
off the accelerator pedal.
(D Note
The tachometer needle@¢ page 10,
fig . 3
shou ld only briefly be in the red
zone: you could damage your engine! The
beg inning of the red zone varies depend­
ing on the engine.
@) For the sake of the environment
Upshifting early saves fuel and reduces en­
gine noise.

respond with max imum stopping power
in critical s ituations . You must allow for
increased braking distances. The extra
d istance used up by fading bra kes could

mission in Neutral.
- 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 . Wait until no steam or
coolant can be seen or heard before care­
fully opening the hood .

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 of automatic trans­
mission to "P" (Park); put manual
transmission in Neutral.
- 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.
