The ill umi nat ion fo r th e i nstru me nt cl uster
lights up whe never yo u switch on the i gni ­
tion with t he
vehicle headlights off . As
the daylight fades, the instrument cluster illumi nat ion likewise dims automatically
a n d w ill go out completely when t he out­
side light is very low. This feat ure is meant
to remind you to switch on the headlights
w hen o utside lig ht con dit io ns become
poor.
Engine coolant temperature gauge
The eng ine coolant gauge q page 10, fig. 3 CD
only works when the ignition is on. To p revent
damage to you r engine, please note the fol­
lowing impor tant po ints:
Engine cold
As long as the needle remains at or close to
the bottom of the gauge, the engi ne still has
not reached its operat ing temperature . Avoid
high eng ine speeds, heavy eng ine loads and
heavy th rottle a pplicat io ns.
Normal temperature
When the engine has reached its operat ing
temperature, the needle w ill move into the
midd le of the gauge and rema in the re. If th e
engine is worki ng ha rd at high outside tem­
peratures, the needle may rise up. This is no
need to worry as long as the. warning light
i n the i nstr ument cluster does not ill uminate.
Warning light in the instrument cluster
When the. warn ing light in the inst rument
cluster s tarts to flash, th is can mean one of
two things : eithe r the coo lant
temperature is .,..

Instrument s and warning /indicator lights 11
too high, or the coolant level is too low
¢ page 32.
If the needle is well in the upper area of the
ga uge , the coolant temperature is too high.
Stop the vehicle , switch the eng ine off and
allow the engine to cool.
If the warning light
comes on again after driving a short distance,
contact an authorized dealer.
A WARNING
- Always observe the warning in
¢
page 257, 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
dr ipping from the engine compartment.
You could bu rn yourself. Let the engine
cool off first until you can no longer see
or hear steam or coolant escaping.
0 Note
- Mount ing additional lights or accessories
i n front of the a ir inlets reduces the cool­
i ng effect of the radiator. At h igh outside
temperatures or high eng ine 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 cou ld reduce the cooling
effect and the engine could then over­ heat. Ask your authorized Audi dealer for
ass istance.
Tachometer (engine rev counter)
The tachometer indicates the engine RPM
(revolutions per minutes).
The tachometer @¢ page 10, fig. 3 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 be low 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 pe­
riod. Before reaching this area , move these­
lector lever to position D (Drive) or ease your
foot off the accelerator pedal.
(D Note
The tachometer needle should not move
into the red range. If it does, then only for
a very short per iod of t i me. You could
damage your engine by driving at high RPM .
@) For the sake of the environment
Upshifting early saves fuel and reduces en­
gine noise .
Digital clock with date display
Fig. 4 In st ru m en t cluster : time a nd da te
The date, time of day, and time and date for ­
mat can be set in the MMI. You can learn more
about this in the MMI manual.
(D Tips
-When open the driver door, the time,
date and odometer are disp layed for an
add itional 30 seconds.
- You can also call up the display with the
!CHECK I button q page 12 while the ig­
nition is switched off.

For example, the symbol II appears in the
display, indicating low windshield washer flu­
id level. The follow ing message also appears:
Pleas e refill w asher fl uid
The driver message disappears after a few
seconds. The driver message can be displayed
again by briefly pressi ng the
!CHECK I button.

"t:::7: Engine oil pressure malfunction
The red engine oil pressure warning symbol
requires immediate servi ce or repair. Driving
with a low -oil -pressure indication is likely to
inflict severe damage to the engine .
If the. symbol appe ars in the display and
b links, the oil press ure is too low . An addition­
a l driver message can also be disp layed by
pressing the
I CH ECK i button :
Switch off engine! Oil pre ssure too low
Immediate actions
~ Pull off the road .
~ Stop the vehicle.
~T urnoff the engine .
~ Check the engine oil lev el with the dipsti ck
¢page 262.
Dipstick readings checks too low
~ Top off o il to the proper level¢ page 263 .
Driver information di spla y 33
~ Make s ure that the oi l pressure wa rning
symbo l. appears no longer in the disp lay
befo re you sta rt driv ing again.
Dipstick reading checks OK
~ If the oil press ure warning symbol.
starts flashing aga in even thoug h the en­
gine oil leve l checks OK on the dipstick,
do
not continue driving and do not let the en­
gine run in idle .
Instead, contact your au­
thori zed A udi dealer for assistance.
(D Tips
- The engine oil pressure symbol. is
not an indicator for a low engine o il 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 b efore going on a long trip .
- The yellow oil level warning indication
l!I requires oil refill or workshop serv­
ice without delay . Do not wait until the
red oil pressure warning. start s to
fla sh before you. respond to th e low oil
level warning l!I. By then, your engine
may already have suffered serious dam­
age.
