Instruments and warning/indicator lights
Warning light in the instrument cluster -t
When the _L warning light in the instrument cluster starts to flash,
this can mean one of two things: either the coolant
temperature is
too high, or the coolant
level is too low~ page 33.
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 the engine to cool.
If the warning light comes on again after
driving a short distance, contact an authorized dealer.
& WARNING
• Always observe the warning in ~ page 324, "Engine compart­
ment", before 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 engine coolant.
0 Note
• Mounting additional lights or accessories in front of the air inlets
reduces the cooling effect of the radiator. At high outside tempera­
tures or high engine load, the engine could overheat.
• The front spoiler has been designed to properly distribute the
cooling air when the vehicle is moving. If the spoiler is damaged,
this could reduce the cooling effect and the engine could then
over­
heat. Ask your authorized Audi dealer for assistance. •
Tachometer (engine rev counter)
The tachometer indicates the engine RPM (revolutions per
minutes).
The tachometer 0 ~ page 13, fig. 2 is the left of the two large clock ­
type displays. The
engine turns at a speed
1,000 times the single digit in the
display, e.g. if the needle is pointing at the "2" the engine is turning
at 2,000 RPM.
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 break -in period. Before reaching
this area, move the selector lever to position "D (Drive)" or ease your
foot off the accelerator pedal.
0 Note
The tachometer needle should not move into the red range. If it
does, then only for a
very short period of time. You could damage
your engine by driving at high RPM .
'£> For the sake of the environment
Upshifting early saves fuel and reduces engine noise.•
Digital clock with date display
Date and time of day can be set in the MM/.
Fig . 3 Instrument
cluster with digital
clock
The date, time of day, and time and date format can be set in the
MMI. You can find out more in the MMI manual. .,_

Instruments and warning/indicator lights
gallons (10-12 liters) of fuel left. This message is meant to remind
you to
refuel.
The total tank capacity of your vehicle is listed in~ page 399 .
0 Note
Never run the tank completely dry. An irregular supply of fuel can
cause engine misfiring and fuel could enter the exhaust system. The
catalytic converter could then overheat and be damaged. •
[ CHECK] button
You can perform different functions with this button.
Fig. 5 CHECK button in
the instrument cluster
The [ CHECK I button performs the following functions:
Switching on the clock and odometer
With the ignition turned off, the odometer reading and the digital
clock with date display can be switched on for about 30 seconds by
pressing the !CHECK ] button ~ fig. 5.
Starting the Auto-Check sequence
The Auto-Check system~ page 30 constantly monitors certain indi­
vidual functions and components of the vehicle when the ignition is
turned on and when the vehicle is moving. With the ignition turned on, you can start the "Auto-Check
sequence" by pressing the
I CHECK] button. You can perform an
Auto-Check sequence when the vehicle is stationary and the ignition
is turned on or when the vehicle is moving not faster than 3 mph
(5 km/hl.
The number of keys programmed to the vehicle is also displayed.
The display
3\3 indicates that three keys have been programmed.
This allows you to make sure you have received all of the keys when
you purchase a used vehicle.
For example, if you only receive two keys, you should take those
keys to your authorized Audi dealer to have the missing key deacti­
vated so it cannot be used. You should also report the missing key
to your insurance company.
Calling up the driver information
A yellow or red symbol appears in the instrument cluster display,
usually with a driver message. The driver message display disap­
pears after about 5 seconds. The driver message can be displayed
again by briefly pressing the
I CHECK I button.
Setting the speed warning
By pressing the I CHECK] button briefly, you can set threshold 1 of
the speed warning while you are driving~
page 39. By maintaining
pressure on the [ CHECK] button, you delete the warning
threshold. •

system goes through a learn ing process for the first few yards . The
warning/indicator light i lluminates . The warning/indicator light
goes out as soon as the learning process is complete.
If the ESP warning/indicator light i lluminates and stays on after you
have started the engine, this may mean that the control system has
temporarily switched off the ESP. If this is case, you can reactivate
the ESP by turning the ignition off and then on again. The
warning/indicator light should go out to show that the system is
fully functional again.
