Contact your authorized Audi dealer as
soon as possible.
- USA models: If the . warning light and
the
rJl1 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 acci­
dent . Have your vehicle repaired immed i­
ately by your authorized Audi dealer or
qualified workshop. Dr ive slowly and
avo id sudden, hard brake applicat ions.
- Canada models: If the brake warn ing
light . and the ABS warning light

i ndi cato r light does not go out, or if it illumi­
nates wh ile you are driv ing, or if it sta rts to
blink, then there is a ma lfunction somewhere
in the system.
If the light does not illuminate
when you switch the ignition on, this also means there is a malfunction.
A WARNING
If you have a malfunction in the safety sys­
tems, contact your author ized Audi dealer
immediately. Otherw ise the safety sys­

Auto Check Control
Some functions and vehicle components are
scanned for their operating status when you
switch the ignition on and whi le you are driv­
ing . Malfunctions or required service proce­
dures are signaled audibly and indicated by
red and yellow illuminated symbols and re­
minders in the d isplay.
A WARNING
--- Never rely exclusively on the outside
temperature display to determine if a
road surface is icy or not . Keep in mind
that road surfaces , espec ially br idges
and overpasses, could be ice covered and
slippery even at an outside temperature
above 41 °F (+S °C).
- Always remember,
even if the "snow­
flake" symbol (ice warning) does not ap­
pear in the disp lay, black ice cou ld be on
the road.
- Always reduce your speed and drive with
specia l care in cold weather conditions
when the chance of encountering icy
road surfaces increases.
¢j) Tips
If the vehicle is stationary, or if you are
driving at a very low speed, the tempera­
ture shown in the display might be slightly
higher than the actual outside tempera­
ture. This i.s caused by the heat being radi­
ated from the engine .

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*.

Single-tr ip m emory (Trip computer 1 )
The single-trip memory stores the trip infor­
mat ion from the time the ignition is turned o n
until it is turned off. If the trip is continued
w ithin 2 hours from the t ime the ignition was
turned off, the new data will be included in
the calcu lation of the current trip i nfo rma­
tion .
If the t rip is inte rrupted fo r more than 2
hours the memory is reset automati ca lly.
Total -trip memory (Trip computer 2)
Unlike the sing le-trip memory, the tota l- tr ip
memory is not reset automatically . Th is per­
mits you to evaluate your d riving data for the
enti re pe riod be tween manual rese ts.
