Instrument s and warning /indicator lights 11
,&_ WARNING
- Always observe the warning in
¢ page 213, 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 engin e RPM
(r evolutions 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 a rea, 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.

hazard. Stop the car and get professional
assistance.
- USA models: If the 1111 warn ing light,
the
G1 warning light and the m;B warn­
ing light come on together, the rear
wheels co uld lock up first unde r hard
braking. Rear wheel lock-up can cause
loss of vehicle con tro l an d an accident .
Have your vehicle repai red immedia tely

- Always keep in mind that after severa l
brake applications, you will need greater
pressure on the brake pedal to stop your
veh icle. Do not rely on strained brakes to
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
le ad to an ac cident.
