@ Tips
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 255, 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 yo urself. Let the engine
cool off first un til you can no longer see
or hear steam or coo lant escaping .
(D Note
- Mounting additional lights or accessories
i n front of the air inlets reduces the cool­
in g effect of the rad iato r. At high outside
temperatures or high engine load, the
engine could overheat.
- The front spoi ler has been designed to
properly distribute the cooling air when
the vehicle is moving. If the spoiler is
damaged, this cou ld red uce the cooling
effect and the engine could then over­
heat. Ask your authorized Aud i dealer for
assistance .
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
eng ine 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 pe­
riod. Before reaching this area, move these­
lector lever to position "D (Drive)" or ease
your foot off the accelerator pedal.
Q) Note
The tachometer needle should not move
i nto 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
Upsh ifting early saves fuel and reduces en­
gine noise .
Digital clock with date display
Fig. 4 In st rum en t cluster : time and date
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.
{!) Tips
- When open the driver door, the time,
date and odometer are displayed for an
add itional 30 seconds.
- You can also call up the display with the
!CHECK I button c:> page 12 while the ig­
nition is sw itched off.

12 Instruments and warning/indicator lights
Speedometer with odometer
The speedometer shows you the vehicle
speed, and the odometer shows you how many miles (kilometers) you have driven.
Fig. 5 Instrument cluster Odometer and reset button
The odometer and trip odometer are located
inside the speedometer.
- USA mode ls - Miles
- Canada models -Kilometers
You can switch the display from miles to kilo­ meters and vice versa via the MMI. You can
find out more in the MMI manual.
Lower odometer
The lower odometer shows the total number
of mi les (kilometers) driven.
Upper odometer (trip odometer)
The upper odometer shows the tota l number
of mi les (kilometers) driven since you last re­
set the odometer to zero. You can use this od­
ometer when you want to keep track of how many miles (k ilometers) you have driven for a
single trip or errand. The last digit indicates
1/10 of a mile (100 meters).
You can reset the trip odometer to zero by
pressing the Reset button
~o.
Malfunction message
If there is a malfunction somewhere in the in­
strument cluster,
dEF will appear in the trip
odometer and will stay on. Contact your au ­
thorized Audi dealer to have the problem cor­
rected.
(D Tips
- When you open t he driver door, the time,
date and odometer are disp layed for an
add itiona l 30 seconds.
- You can also call up the display with the
I CHECK I button c> page 12 while the ig­
nition is switched off.
Fuel gauge
The fue l gauge only works when the ignition is
on .
When the needle reaches the reserve mark,
the
c> page 35 00] symbol appears in the in­

@ Note
Never run the tank completely dry. An ir­
regular supply of fuel can cause engine
misfiring and fuel could enter the exhaust
system. The catalytic converter could then
overheat and be damaged.

0 Adaptive Air Suspension
Applies to vehicles: with Adaptive Air Suspension
This IIJ warning/indicator light has the fol­
l owing functions:
- It illuminates for a few seconds after the ig­
nition is tu rned on as function check and
then goes out .
- If the warning/ind icator light illuminates or
blinks continuously, there is a system fau lt
in the Adaptive A ir Suspension . A system
fault can result in limited ride comfort and
low ground cl earance . Drive safely to the
nearest authorized Aud i dealer or qualified
workshop, and have the fault corrected .
- If the warning/ind icator light flashes, you
should not drive the vehicle. The flash ing
warning/ind icator light po ints to an extreme
High level. A very
pronounced lifting of the
vehicle (extreme High level) can resu lt, fo r
example, when a heavy load is removed
from the vehicle. As soon as the leve l has re­
turned to normal, the warning/indicator
light stops flashing, and yo u can drive away.
- If the warning/ind icator light flashes in con ­
junction with the
II warning/indicator
light, you sho uld not drive off immediate ly
i n order to prevent damage to the under­
body . The two warning/ind icator lights flashing together points to an extreme Low
level. A very
pronounced lowering of the ve­
hicle (extreme Low leve l) can result, for ex­
ample, from a heavy load . As soon as the
level has returned to normal, the warning/
ind icator lights stop flashing, and you can
dr ive away.
(D Note
If the warning/indicator light flashes in
conjunction with the
II warning/ind ica-
tor light, you should not dr ive the veh icle
because low-lying veh icle parts can bot-
tom out as you d rive over uneven ground
a n d be damaged as a result.

controls.
- If the warning/indicator light flashes in con­
junction with
the m warning/indicator
light, you should not drive the veh icle imme ­
diately in order to prevent damage to the
underbody. The two warn ing/ indicator
lights flashing together points to an ex­
treme Low level. A very
pronounced lower­
ing
of the vehicle (extreme Low level) can re­
sult, for example, from a heavy load. As
soon as the level has returned to normal,
