thorized Audi dealer as soon as possible.
A WARNING
- If the 9 (USA models)/ll] (Canada mod­
els) warning light does not go out, or if it
comes on while driving, the ABS system is
not working properly. The vehicle can then
be stopped only with the standard brakes
(without ABS). You will not have the protec­
tion ABS provides. Contact your Audi dealer
as soon as possible.
- USA models: If the 1111 warning light, the
DJ warning light and the 9warning 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 im­
mediately by your authorized Audi dealer or
a qualified workshop. Drive slowly and avoid
sudden, hard brake applications.

_& WARNING
--Never rely exclusively on the outside tem­
perature display to determine if a road sur­
face is icy or not. Keep in mind that road
surfaces, especially bridges and overpasses,
could be ice covered and slippery even at an
outside temperat ure above 41 °F (+S °C).
- Always reduce your speed and dr ive with
special care in cold weather conditions when
the chance of encountering icy road surfaces increases .
(D Tips
-You can select the units used for tempera­
ture, speed and other measurements in the
MMI.
- If the vehicle is stationary, or if you are driv­
ing at a very low speed, the temperature
shown in the display might be slightly high­
er than the actual outside temperature . This
is caused by the heat being radiated from
the engine .

On-board computer
Fig. 8 Instrument cluster: fuel consumption display
You can call up the following informat ion in the
on-boa rd computer:
- Date
- Dr iving t ime from the short-term memory
- Average consumption from the short-term
memory
- Average speed from the short-term memory
- Distance driven from the short-term memory
- Current fuel consumption
- Short-term memory overview
- Long-te rm memory
overv iew
The short-term memory collects driving informa­
tion from the time the ignition is switched on un­
ti l it is switched off. If you continue driving with­
i n two hours after switching the ignition off, the
new values are included when calculating the cur-
rent trip information.
II>

Unlike the short-term memory, the long-term
memory is not erased automatically. You can se­
lect the time period for evaluat ing trip informa­
tion yourself.
F or some vehicle functions, you can access driv­
ing information from the short-term memory
consecutively in the line ©~
page 23, fig. 5 by
turning the thumbwheel @.
Fuel consumption
The cu rrent fue l consumption can be shown us­
ing a bar graph¢
fig. 8. The average consump­
tion stored in the short-term memory is also dis­
p layed. If the bar is green, your vehicle is saving
fuel through one of the following functions:
- Recuperation : electrical energy can be stored in
the battery when the vehicle is coasting or driv­
ing downh ill. The bar will move toward 0.
-Cylinder on demand system*: the engine auto­
matically switches four cylinders
(4.0L TFS!) or
six cylinders (6.3L FSI) off when lower power
output is required and other conditions are met . This change is not noticeable to the pas­
sengers. The cylinders will switch on again
when higher power output is needed.

- Only reset the oil change display when you
have completed an oil change.
- If you disconnect the battery terminals, no
calculations can be made for the service in­
terval display during this time and no serv­
ice remi nder w ill appear. Remember that
observing the proper service interva ls is v i­
