Instrument s and warning /indicator lights 11
Warning light in the instrument cluster
display
If the. warning light in the instrument clus ­
ter disp lay flashes, this can mean one of two
things: either the coolant
t empera ture is too
high, or the coolant
level is too low
¢ page 31.
If the needle is well in the upper area of the
gauge, the coolant temperature is too high.
Stop the vehicle, switch the engine off, and
allow it to cool.
If the warni ng light comes on
again after driving a short distance, contact
an author ized Audi dealer or other qualif ied
workshop.
_& WARNING
- Always observe the warning in
¢ page 230, 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 e ngine coolant .
CD Note
-Mounting additional lights or accessories
in front of the a ir inlets reduces the cool­
ing effect of the rad iator. At high 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 co uld then over­
heat. Ask you r aut horized Aud i dealer for
assistance.
Tachometer (engine rev counter )
The tachometer indicates the engine RPM
(revolutions per minutes).
If engine RPM drops be low 1,500, you should
downshift to the next lower gear . Th e red area at
the end of the scale indicates maximum
perm issible eng ine 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.
CD Note
The tachometer needle @ ¢ page 10,
fig. 3
should on ly briefly be in the red
zone: you cou ld damage your eng ine! The
beginn ing of the red zone var ies depend-
i ng on the engine.
@) For the sake of the environment
Upshifting early saves fuel and reduces en­
gine noise .
~button
You can perform different func tions with this
button.
Fig . 4 SET but ton in t he in strumen t cl uster
T he !S ET ! button performs the following func ­
tions :
Switching on time, date, temperature
display, and odometer
The display appea rs fo r approximately 30 sec­
onds when you press the
! S ET ! button¢ fig . 4
with the ignit ion off.
Starting the Auto -Check sequence
The Auto-Check system ¢ page 28 constant-
ly mon itors certa in individua l functions and
components of the vehicle when the ignition
is turned on and when the vehicle is moving.
With the ign ition turned on, you can start the
"Auto-Check sequence" by pressing the
i S ET i liJJ,,

12 Instruments and warning/indicator lights
button. You can perform an Auto-Check se­
quence when the veh icle is stationary and the
ignit ion is turned on or when the vehicle is
moving slower than 3 mph (5 km/h).
Calling up the drive r information
A yellow or red symbol appears in the instru­
ment cluster display, usually with a driver
message . The driver message display disap­
pears after about
S seconds. The driver mes­
sage can be displayed again by briefly press­
ing the
! SET ! button.
Setting the speed warning
By pressing the I SET ! button briefly, you can
set threshold 1 of the speed warning while
you are driv ing
¢ page 28. By mainta ining
pressure on the
ISETI button, you delete the
warning threshold.
Digital clock with date display
Fig. S Ins trumen t cluster: time and da te
Digital clock
The date, time of day, time and date format
can be set in the radio or MMI *. You can learn
more about this in the MMI manual or in the
radio user's manual.
@ Tips
- The dig ital clock turns on for about 30
seconds when the driver's door is
opened.
- When the ignition is turned off, the od­
ometer reading and the digital clock with
date display can be switched on for
--about 30 seconds by pressing the iSE Ti
button ¢ page 11, fig . 4.
Fuel gauge
The fuel gauge works only when the ignition is
on.
When the needle reaches the red area, the
Ii
warning light in the instrument cluster will il­
luminate ¢
page 35. This means you have
approximately
2 .1 ga llons (8 liters) of fuel
left in the tank.
Time to refuel!
The total tank capacity of your vehicle is listed
in
¢ page 292.
(D Note
Never run the tank completely dry! An ir­
regular supply of fuel can cause engine
misfiring and fuel could enter into the ex­
haust system. The catalytic converter
could then overheat and be damaged.
Odometer
The odometer indicates the distance driven.
