gauge turn on under normal d riving condi ­
tions . The LEDs higher up may turn on when
the eng ine is under heavy load or the exter ior
temperature is high . This is no need to worry
as long as the. warning light in the instru­
ment cluster does not illuminate . If the LEDs
in the upper area of the display and the ind ica­
tor light . in the instrument cluster d isplay
turn on, the coolant temperature is too high
¢page 16.
A WARNING
-Always observe the warning in
~ page 226, 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
dr ipping 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 a ir inlets reduces the cool­
i ng effect of the rad iator . At h igh outside
temperatures or high eng ine load, the
engine co uld overheat.
- The front spo ile r has been designed to
properly distrib ute the cooling air when
the veh icle is moving. If the spoiler is
damaged, this cou ld red uce the cooling
effect and t he engine co uld then over­
heat . Ask your aut ho rized Audi dea le r for
ass istance.
Tachometer (engine rev counter)
The tachometer indicates the engine RPM
(revolutions per minutes).
If engine R PM drops be low 1,500, you should
downshift to the next lower gear. The red a rea
at the end of the sca le ind icates maxim um
perm iss ible engine RPM after the break-in pe­
riod. Before reaching this area, move these­
lector lever to position "D (Drive)" or ease
your foot off the accelerator pedal.
@ Note
The tachometer need le should only briefly
be in the red zone: yo u could damage your
engine! The beg inning of the red zone var ­
i es depending on the engine.
@ For the sake of the environment
Upsh ifting early saves fuel and reduces en ­
gine noise.
Fuel gauge
The fuel gauge only works when the ignition is
o n.
If the fue l level drops below 4 gallons (15
l ite rs), the bottom LE D tu rns red and the indi­
cator light~ turns on
c::> page 21. The bot­
tom LED b link s red when the fue l level is very
l ow .
The possible range based on the current fuel
level is shown in tab@~
page 23, fig. 4.
(D Note
Never run the ta nk complet ely dry. An ir­
r egular supply of f uel can cause engine
misfiring and fuel cou ld enter the exha ust
system. The cata lytic converter could t hen
overheat and be damaged.
