The instrument illumination (for dia ls and
needles) t urns on when the ignition is on
a nd the vehicle lights are tur ned off. As
the daylight fades, the illumination of t he
dia ls likewise dims automatica lly and w ill
go o ut comple tely when the o utsi de light
i s very low. Th is feature is meant t o rem ind you
to sw itch on the head ligh ts when o ut­
s id e light condi tions become poor .
Engine coolant temperature gauge
The engine coolant gauge (!) ¢ poge 10, fig. 3
only works when the ignition is on. To prevent
damage to your engine, please note the fol­
lowing important po ints:
Engine cold
If only the LEDs at the bottom of the gauge
turn o n, the engine has not reached operating
temperature yet. Avoid hig h engine speeds,
heavy engine loads and heavy throttle applica­
tions .
Normal temp erature
The eng ine has reached its operating temper-
at ure once the LEDs up to the center of the .,.

Instrument s and warnin g/indic ator ligh ts 11
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.

(USA models): If the warning light 1111 and
the warning light
EiJ appear together, imme­
diately contact your authorized Audi dealer or
qualified workshop to have all brake pads in­
spected
¢ page 20 .
When t he light comes on, an audible warning
signal is also given.
A WARNING
-Always observe the warnings in
¢ page 226, Engine compartment, be­
fore opening the hood and checking the
brake fluid .
- Driving with low brake fluid is a safety
hazard. Stop the car and get professional
assistance.
- USA models: Ifthe llll warning light,
the
G1 warning light and the firlilJ warn­
ing light come on together, the rear
wheels could lock up first under hard braking. Rear wheel lock-up can cause
loss of vehicle control and an accident.
Have your vehicle repaired immediately
by your authorized Audi dealer or a quali­
fied workshop. Drive slowly and avoid sudden, hard brake applications.
- Canada models: If the brake warning
light ., the
DJ warning light and the
ABS warning light
BJ come on together,
the rear wheels could lock up first under
hard braking. Rear wheel lock -up can
cause loss of vehicle control and an acci­
dent . Have your vehicle repaired immedi­
ately by your authorized Audi dealer or a
qualified workshop. Drive slowly and
avoid sudden, hard brake applications.
- If the brake warning/indicator light does
not go out after a few seconds and the
parking brake is released, or lights up
while you are driving, the fluid Level in
the brake fluid reservoir is too low. If you
believe that it is safe to do so, proceed
immediately at low speed to the nearest
authorized Audi dealer or qualified repair
facility and have the brake system in­ spected. -
Always keep in mind that after several
brake applications, you will need greater
pressure on the brake pedal to stop your
vehicle. Do not rely on strained brakes to
respond with maximum stopping power
in critical situations. You must allow for
increased braking distances. The extra
distance used up by fading brakes could
lead to an accident.
PARK/( ®) Electromechanical parking
brake
The warning/indicator light monitors the
electromechanical parking brake.
If the indicator light - (USA models)/ .
(Canada models) turns on, the parking brake
was set. If the parking brake is set when the
ignition is off, the indicator light turns off af­
ter about 20 seconds.
Th e warning/indicator light will go out when
the parking brake is released.
