& WARNING
• USA models: If the BRAKE warning light and the I warning
light come on together, the rear wheel s could lock up first under
hard braking . Rear wheel lock-up can cause loss of vehicle control
and an accident. Have your vehicle repai red immediately by you r
authorized Audi dealer or a qualified workshop. Drive slowly and
avoid sudden, hard brake applications.
• Canada models : If the brake warning light ((j)) and the ABS
warning light
~ come on together , the rear wheels could lock up
first under hard braking . Rear wheel lock-up can cause loss of
vehicle control and an accident. Have your vehicle repaired imme­
diately by your authorized Audi dealer or a qualified workshop .
Drive slowly and avoid sudden , hard brake applications.
• If the brake warning /indicator light does not go out after a few
second s and the parking brake released , or lights up while you are
driving , the fluid level in the brake fluid reservoir i s too low. If you
believe that it is safe to do so , proceed immediately at low speed
to the neare st authorized Audi dealer or qualified repair facility
and have the brake system inspected .
• Always keep in mind that after several brake applications, you
will need greater pressure on the brake pedal to stop your vehicle.
Do not rely on strained brake s to re spond with maximum stopping
power in critical situations. You must allow fo r increased braking
di stan ce s. The extra distance used up by fading brakes could lead
to an accident. •

tions and vehicle components are scanned for their operating status. Malfunctions or required service procedures are signaled audibly and
shown by red and yellow lighted symbols and reminders to the driver
in the display.
The driver is also shown information about radio and CD operation
and directions for the navigation system*. You can find additional
information on these subjects in the MMI manual.
The illustrations in the instrument panel display differ in some of the
vehicles.

T he unit of measurement for the temperature can be set in either ° F
or in °Con the MM I* or on the radio co ntrol unit. The ou ts ide tempe r­

& WARNING
• Never use the outside temperatu re display to determine if a
road surface i s ic y or not . Keep in mind that road surfaces, espe­
cially bridges and o verpasses , could be ice covered and slippery
even at an out side temperature above 41 °F (+5 °C ).
• Always remember , even if the "snowflake " symbol (ice
warning ) does not appear in the di splay, black ice could be on the
road.
• Always reduce your speed and drive with special care in cold
weathe r conditions when the chance of encountering icy road
s urfaces increa se s.
[I) Tips
If the vehicle is s tat ionary, or if yo u are dr iv ing a t a very low speed, the
temperature shown in the d isplay m ight be slightly higher than the
act ua l ou tside tempe ra tur e. This is caused by the heat being radia ted
from the engine. •

Trip computer
Introduction
The trip
computer gives you information on current and
average fuel mileage, average speed, fuel range and
driving time.
Fig. 14 Trip computer
display: Average fuel
m ile age
The follow ing information is continuously evaluated by the trip
computer and can be displayed sequentially in the instrument cluste r
display:
Fuel range
The estimated cruising range in miles (km) appears in the display .
Thi s tells you how far your vehicle w ill be able to travel on the current
tank of fuel and with the same dr iv in g style . The display changes in
increments of 6 miles (10 km).
The cruising range is calculated based on the fuel consumption for
the last 18 miles (30 km). If you drive conservatively, the cruising
range will increase.
Average fuel mileage
The average fuel economy in MPG {l/100 km) since you last cleared
the memory appears in this disp lay . You can use this display to adjust
your dr iv ing tech nique to achieve a desired mileage . .,_
Vehicle care Technical data

Driver information display
Current fuel mileage
The instantaneous fuel consumption in miles per gallon (l/100 km) is
shown in this display. You can use th is display to adjust your driving
technique to achieve a desired mi leage.
Fuel consumption is reca lculated at intervals of 33 yards (30 meters).
This display switches to gallons/hour (liters/hour) when the vehicle is
not moving .
Average speed
The average speed in mph (km/h) since the last time the display was
reset appears in the display.
Elapsed time
Th e length of time that you have been driving since you last reset the
memory appears in this display.
Distance
The distance that has been cove red since the last time the memory
was cleared appears in the display.
[I) Tips
• Fuel consumptions (average and current), range and speed are
displayed in metr ic units on Canad ian models.
• All stored values will be lost if the vehicle battery is
disconnected . •
Memories
The trip computer is equipped with two fully automatic
memories as well as an efficiency program.
Fig. 15 Trip computer
disp lay : memory level

You can switch between the trip computer 1 and 2 and the efficiency
program* by pressing the [
RESET] button@=> page 23, fig. 16.
You can tell which memory level is currently active by the number or
the sign in the display=> fig . 15. The data from the single-trip
memory (memory level 1) is being disp layed if a
1 appears in the
display. If a
2 is shown, then the data from the total-trip memory is
being disp layed (memory level 2). The fuel pump nozzle
ii1 ind icates
the efficiency program*=>
page 24.
Single-trip memory (Trip computer 1)
The single-trip memory stores the trip information from the time the
ignition is turned on until it is turned off. If the tr ip is cont inued
within 2 hours from the time the ign ition was turned off, the new
data will be incl uded in the calculation of the current trip inf orma­
tion. If the trip is interrupted for
more than 2 hours the memory is
reset automa tically.
Total-trip memory (Trip computer 2)
Unlike the sing le-trip memory, the total-trip memory is not reset
automatically. This permits you to evaluate your driving data for the
entire period between manual resets.
