vehicle headlights are off . Be aware o f the
f ollowing diffe re nc e betwee n mode ls built
t o US or C ana di an specific ati ons :
-USA models: illumination of the instru­
ment clu ster (gauges and needles),
dash and center console around the
gearshift lever is controlled by a light
sensor located in the instrument panel.
The instrument panel illumination will automatically become dimmer as the daylight fades away and eventually will
go out completely when outside light is
very low . This is to remind you, the driv­
er , to switch on the headlight s before it
gets too dark.
- Canada model s: instrum ent pan el illu­
mination will stay bright regardless of
the intensity of ambient light. Always be aware of changes in out side light
conditions while you are driving. Re­
spond in time to fading daylight by
turn ing the light switch to position
iD
(or ,;AUTO" if your car is equipped w it h
this feat ure)

Tachometer (engine rev counter)
The tachometer indicates the engine RPM
(revolutions per minutes).
The tachometer CD c> page 10, fig. 3 is the left
one of the two large clock-type d isplays.
T he eng ine turns at a speed
1 000 times the
s ingle digit in the display, e.g . if the needle

ant
level is too low ¢ page 17.
.&_ WARNING
- Always observe the warning in
¢ page 187, Engine compartment be­
fore opening the engine hood and check­
ing the engine coo lant level.
- Never open the engine hood if you see or
hear steam, or if you see engine coolant
dr ipping from the eng ine compartment.
You could burn yourself . Let the engine
cool off first so that you cannot hear or
see any steam or engine coolant .
0 Note
-Mounting additional l ights or accesso ries
i n 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 could 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 reduce the cooling
effect and the engine could then over­
heat. Ask your authorized Audi dea ler for
assistance.
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
lum inate <=>
page 21 lil This means you
have approximately
1.8 gallons (7 liters) of
fuel left in the tank .
Time to re fu el!
The total tank capacity of your vehicle is listed
in¢
page 257, Data.
(D Note
Never run the tank completely dry! An ir­
regular supply of fuel can cause eng ine
m isfiring and fuel could enter into the ex­
haust system. The catalyt ic converte r
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.

The lower odometer shows the total number
of miles (kilometers) driven.
Uppe r odometer (trip odome ter)
The upper odometer shows the total number
of miles (kilometers) driven since you last re­
set the odometer back to zero. You can use
th is odometer when you want to keep track of
how many miles (kilometers) you have driven
for a single tr ip or errand. The last digit ind i­
cates 1/10 of a mile (100 metres) . You can set
the tr ip odomete r back to zero by pressing the

immediately by your authorized Audi
dealer or a qualified workshop. Drive
slowly and avoid sudden, hard brake ap­ plication.
- Canada models: If both, the brake warn­
ing light . and the ABS warning light
Ii] come on at the same time, the rear
wheels could lock up first under hard braking. Lock-up of the rear wheel brakes
can cause loss of vehicle control and an
acc ident. Have your vehicle repaired im­
med iately by your authorized Audi 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
park ing brake re leased, or lights up while
you are driving, the fluid level in the brake flu id reservo ir is too low. If you be­
lieve that it is safe to do so, proceed im­
med iately at low speed to the nearest
authorized Audi dealer or qualified work­
shop and have the bra ke system inspect­
ed.
- Always keep in m ind that afte r several
brake applicat ions, you will need g reater
pressure on the b rake peda l to stop your
vehicle. Do not re ly on strained brakes to
respond with maxim um stopping power
in critical situations . You must allow for
increased brak ing distances. The extra
distance used up by fad ing brakes could
lead to an acc ident.

~ Diesel particulate filter clogged
Applies to vehicles: with diesel engine and diesel particu­
late fi lter
1/1 Particulate filter ! See owner's manual
If the indicator light II in the instrument
cluster comes on, the diesel particulate filter has become blocked with soot as the result of
constant short-distance driving. When the
II symbol illuminates, you can alter your
driving style to assist the filter self-clean ing
p rocess. Drive for approximately 15 minutes
in 4th or 5th gear (automatic transmission with the se
lector lever in the S position) at a
minimum speed of 37 mph (60 km/h) and an
engine speed of approx imately 2,000 RPM .
The temperature increase that will result from
this can burn off the soot in the filter. The
symbol will switch off when the cleaning is
