- When switching the ignition on, the nee­
dles in the instrument cluster swing up­
ward briefly.
- The illumination for the instrument clus­
ter lights up whenever you switch on the
i gnition with the
vehicle headlights off .
As the daylight fades, the instrument
cluster illumination likewise dims auto­
matically a nd will go out completely
when the outside light is
very low. This
feature is meant to remind you to switch
on the headlights when outside light
conditions become poor .
Engine coolant temperature gauge
The engine coolant gauge q page 10, fig. 3 CD
only works when the ignition is on. To prevent
damage to your engine, please note the fol ­
lowing important points:
Engine cold
If the needle is at or close to the bottom of
the gauge, the engine has not yet reached its
operating temperature. Avoid high engine
speeds, heavy engine loads, and heavy throt ­
tle app lications.
Normal temperature
When the engine has reached its operating
temperature, the needle will
move to the mid­
dle of the gauge and remain there . If the en­
gine is working hard at high outs ide tempera­
tures, the needle may
move higher on the
gauge. This is not a cause for concern as long
as the . warn ing light in the instrument
cluster display does not illuminate. If the.
warning light in the instrument cluster dis­
play flashes, this can mean one of two things:
either the coolant
temperature is too high, or
the coolant
level is too low¢ page 17 Ill-

Instrument s and warning /indicator lights 11
A WARNING
- Always observe the warning in
c::> page 214 , 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 .
(D Note
-Mounting additional lights or accessories
in front of the air inlets reduces the cool­
ing effect of the rad iator. At high outside
temperatures or high eng ine load , the
engine could overheat.
- The front spoiler 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 co uld then over­
heat. Ask your authorized Aud i dealer for
assistance.
Tachometer (engine rev counter)
The tachometer indicates the engine RPM
(revolutions per minutes).
I f engine RPM drops below 1,500, you should
downshift to the next lower gear . T he red area
at the end of the scale indicates maximum
perm issible engine RPM after the break-in pe­
riod. Before reaching this area, move these­
lector lever to position 0/5 or ease your foot
off the accelerator pedal.
@) Note
The tachometer needle@c::> page 10 ,
fig. 3 shou ld only briefly be in the red
zone: you could damage your engine! The
beg inning of the red zone varies depend-
ing on the engine .
@) For the sake of the environment
Upshifting early saves fuel and reduces en­
gine noise.

't:::7: Engine oil pressure
The red en gine oil pressure warning symbol
requires immediate service or repair . Driving
with a low-oil -pressure indication is likely to
inflict severe damag e to the engine.
• Turn off engine! Oil pressure too low
If th e ind ic a tor lig ht tur ns on an d th e me s­
sage a ppears, the oil press ure is too low .
~ Pull off the road.

(D Tips
- The engine oil pressure symbol. is
not an indicator for a low engine oil 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 before going on a long trip.
- The yellow oil level warning indication
Ill requires oil refill or workshop serv­
ice without delay . Do not wait until the
red oil pressure warning. starts to
flash before you respond to the low oil level warning

Trip computer
Introduction
Applies to vehicles: with trip computer
The trip computer gives you information on
current and average fuel mileage, average
speed, fuel range and driving time .
Fig. 9 Trip comp uter d isp lay : Ave rage fuel mileage
The following information is continuously
eva luated by the trip computer and can be dis­
played sequentia lly in the instrument cluster
disp lay:
Fuel range
The estimated cruising range in miles (km)
appears in the display. This tells you how far
your vehicle wi ll be able to travel on the cur­
rent tank of fuel and with the same driving
style. The display changes in increments of
5 miles (10 km).
The cruising range is calcu lated based on the
fuel consumption for the last 18 miles
(30 km). If you drive conservatively, the cruis­
ing range will increase.
Average fuel mileage
The average fuel economy in MPG (l/100 km)
since you last cleared the memory appears in
this display. You can use this disp lay to adjust
your driving technique to achieve a desired mileage.
Current fuel mileage
The instantaneous fuel consumption in miles
per gallon (l/100 km) is shown in this disp lay.
You can use this display to adjust your driving
technique to achieve a desired mileage.
Driver information display 25
Fuel consumption is recalculated at intervals
of 33 yards (30 meters). This display switches
to gallons/hour (liters/hour) when the veh icle
is not moving .
Average speed
The average speed in mph (km/h) s ince you
last reset the memory appears in the display.
Elapsed time
The length of time that yo u have been driving
s inc e you last reset the memory appears in
this display.
Distance
The distance that has been covered since the
last time the memory was cleared appears in
the display.
(0 Tips
- Fuel consumptions (average and cur ­
rent), range and speed are displayed in
metric units on Canadian models.
- All stored values will be lost if the vehi­
cle battery is disconnected.
Memories
App lies to vehicles: wi th trip computer
The trip computer is equipped with two fully
automatic memories as well as an efficiency
program*.
Fig. 10 T rip comput er dis play: memory lev el 1
You can switch between the trip computer 1
and 2 and the efficiency program* by pressing
the
I RESET I button @c::> page 26, fig. 11 .
You can tell which memory leve l is currently
active by the number or the sign in the display .,..
