- When switching the ignition on, the nee­
dles in the instrument cluster move up­
ward briefly.
- The illumination for the instrument clus ­
ter lights up whenever you switch on the
i gnition with the
vehicle headlights off .
As the daylight fades, the instrument
cluster illumination likewise dims auto­
matically a nd will go out completely
when the outside light is very low. This
feature is meant to remind you to switch
on the head lights when outside light
conditions become poor .
Tachometer (engine rev counter)
The tachometer indicates the engine RPM
(revolutions per minutes) .

~
~
"'
If engine RPM drops below 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 br eak-in pe­
riod. Before reaching this area, move these­
lector lever to position "D (Drive)" or ease
your foot off the acce lerator pedal.
(D Note
The tachometer needle should only briefly
be in the red zone: you could damage your
engine! The beg inning of the red zone var­
i es depending on the engine.
@ For the sake of the environment
Upshifting early saves fuel and reduces en­
gine noise.

Engine coolant temperature gauge
The engine coo la nt gauge ¢ page 10 , fig. 3@
only works when the ign ition is on. To prevent
damage to your e ngine, please note the fo l­
l owing important points:
Engine cold
As long as the nee dle rem ains a t the left end
of the gauge, the engine s till h as not reac hed
its operating temperat ure. Avoid high engine
speeds, heavy engine loads and heavy throt­
tle.
Normal temperature
W hen the engine has re ache d its ope rat ing
temperature, the need le w ill move into the
mid dle of t he gauge and rema in there .
If the
engine is working hard at high outside tem ­
peratures, the needle may turn fu rther to the
right. This is no cause for concern as long as
the . warning light in the instrument cluster
does not illuminate .
When the. warning light sta rts to flash,
th is can mean one of two things: either the
coolant
temperature is too high, o r the coo l­
ant
level is too low ¢ page 17 .
A WARNING
--Always obs erv e th e war ning in
¢ page 164 before openi ng the eng ine
h o od and che ck ing t he e ngine coolant
leve l.
- N ever open t he eng ine hood if you see or
he ar steam, or if you see engi ne coo lant
drippin g from t he en gine compar tment .
You could burn yourse lf . Let the engi ne
coo l off fi rst until yo u can n o longe r see
or hea r steam or coolant escap ing.
(D Note
- M ounting ad ditiona l lights or accessories
i n fr ont of the air inlets reduces the coo l­
ing effect of t he radiato r. At high o utsi de
tempe rat ures or h igh engine load, the
eng ine could overheat.
- The front spoiler has been designed to
properly d istribute the cooling a ir when
the vehicle is movi ng. If the spoiler is
damaged, this could reduce the coo ling
e ff ect a nd th e eng ine could then ove r­
heat . As k yo ur au thori zed A udi deal er for

12 Instruments and warning/indicator lights
Fuel gauge
The fuel gauge works only when the ignition is
on . When the needle reaches the red area, the
warning light in the instrument cluster will il­
luminate ¢
page 20 Ill Time to refuel!
The total tank capacity of your veh icle is listed
in
¢ page 223
CD Note
Never run the tank completely dry! An ir­
regula r supply of fue l can cause engine

could then overheat and be damaged.
Speedometer with odometer
The speedometer shows you the vehicle
speed , and the odometer shows you how
many miles (kilometers) you have driven.
Fig . S Spee domete r close -up: odometer display
The dis tance driven is shown in miles (USA
models) or in kilometers (Canada models) .
Lower odometer
The lower odometer shows the total number
of miles (kilometers) driven.
Upper odometer (trip odometer)
The upper odometer shows the total number
of mi les (kilometers) driven since you last re­
set the odometer back to zero. You can use
this odometer wh en you want to keep track of
how many miles (kilometers) you have driven
for a sing le trip or errand. The last digit indi­
ca tes 1/10 of a mile (100 me ters). You can se t the trip odometer
back to zero by pressing the
reset button

BRAKE/ ((D) Brake system
This warning/indicator light illuminates when
the brake fluid level is too low or when there
is a malfunction in the ABS, or when the park­
ing brake is set.
If the. (USA models) . (Canada models)
symbol flashes in the display with the parking
brake released , there is a malfunction in the
brake system. In addition to the symbol, one
of two messages appears in the display:
Stop vehicle and check brake fluid level
Stabilization program and ABS fault! See
Owner's manual
.,. Pull off the road and stop the veh icle.
.,. Obtain profess ional assistance.
USA models: if there is a ma lfunction in the
ABS system, the
II warning/indicator light il­
luminates along with the. system malfunc­
t ion warning/indicator light
Q &. .
Canada models: if there is a malfunction in
the ABS system, the
[IJ warning/indicator

Q&. ,
The light . (USA)/ . (Canada) illuminates
when the ignition is turned on. It goes o ut af­
ter the engine has been started and the park­ ing brake is fully released . This indicates that
the brake warn ing light is funct ion ing proper­
ly.
If the brake warning light does not light up
when the engine is cranking or the parking
brake is applied, there may be a malfunction
in the electrical system. In this case, contact
your Audi dealer.

_& WARNING
-Always observe the wa rni ngs in
¢ page 164, Working in the engine
compartment,
before opening the en­
gine hood and check ing the brake fluid.
- Driving with low brake fluid is a safety
hazard! Stop the car an d get professiona l
assistance.
- USA models: If both, the. warning
light and the
Ill warning light come on
at the same time, the rear wheels could
lock up first under hard brak ing . Lock-up
of the rear whee l brakes can cause loss of
vehicle control and an accident. Have
yo ur vehicle repaired immed iately by
you r autho rized Aud i dealer o r a quali­
fied workshop . D rive slowly and avo id
s u dden, hard brake application .
-Canada models: If both, the brake warn ­
ing light . and the ABS warning light
[iJ come on at the same t ime, the rear
wheels co uld lock up first unde r hard
braking . Lock -up of the rear wheel brakes
can cause loss o f vehicle control and an
acc ident. Have your vehicle repaired im­
med iate ly by your authorized Aud i dealer or a qualified workshop
. Drive slowly and
avoid sudden, hard brake application .
- 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 dr iving, the f lu id leve l in
the brake flu id reservo ir is too low . If you
be lieve that it is safe to do so, proceed
immed iate ly at low speed to the nearest
author ized Audi dealer or qualified work­
shop and have the brake sys tem inspect­
ed .
- Always keep in mind that after severa l
brake applications, you will need greater
pressu re on the brake pedal to stop you r
vehicle . Do not rely on strained brakes to
respond with maximum stopping power
in critical s ituations. You must allow for
increased braking distances. The extra
distance used up by fading brakes could lead to an accident.
tli1 ! .'!r Safety systems
The . (USA models) /. (Canada models)
indicato r light monitors the safety systems
e.g. (a irbags, pre tensioners) and ill uminates
f or a few se conds eac h time you swi tch the ig­
nition on.
If the . (USA models)/ . (Canada models)
i ndicato r ligh t does no t go o ut, o r if it illum i­
na tes while yo u are driving, or if it starts to
blink, then there is a mal function somewhe re
in the system. If the light does not i lluminate
when you switch on the ignition , th is also
means there is a malfunct ion.
_& WARNING
If yo u have a ma lfunction in the safety sys­
tems, co ntact your authorized Aud i dea ler
immediately. Otherwise the safety sys­
tems may not work properly in an acc i­
dent.

~ Engine oil pressure
The red engine oil pressure warning symbol
requires immediate service or repair .
If the . symbo l appears in the disp lay and
flashes, the o il pressure is too low . In add ition
to the symbol, the followi ng message also ap ­
pears in the display :

(D Tips
- The engine oil pressure symbol. is
not an indicator for a low engine oil lev­
el. Do not rely on it. Instead, check the oil level in your engine at regular inter­
vals, preferably each time you refuel, and always before going on a long trip .
- The yellow oil level warn ing indication
Ill requires oil refill or workshop serv­
ice without delay. Do not wait until the
red oil pressure warning symbol.
starts to flash before you respond to
the low oil level warning
II . By then,
your engine may already have suffered
serious damage.
