"'
If engine 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 br eak-in pe­
riod. Before reaching this area, move these­
lector lever to position "D (Drive)" or ease
your foot off the acce lerator pedal.
(D Note
The tachometer needle should only briefly

Upshifting early saves fuel and reduces en­
gine noise.

Auto Check Control
Some f unct ions and vehicle components are
scanned for their operati ng sta tus when yo u
switch the ign ition on and whi le you a re driv­
ing. Malfunctions or req uired service proce­
dures ar e signaled audib ly and indicated by
red and yellow i lluminated symbols and re ­
m inders in the display.
A WARNING -
- Never rely exclusively on the outside
temperature display to determine if a
road surface is icy or not . K eep in m ind
that road surfaces, espec ially br idges
and overp asses, co uld be ice covered and
slippe ry even at an outside tempe ra tu re
above 4 1 °F (+5 °C).
- Always remembe r, even if the "snow­
f lake" symbo l (ice warning) does not ap­
pear in the disp lay, black ice could be on
the road .
- A lways reduce your speed and d rive with
specia l care in cold weather cond itions
when the chance of encountering icy
road surfaces increases.
(D Tips
- If the vehicle is stationary, or if you are
dr iving at a very low speed, the tempera­
t u re s hown in the d isp lay m ight be
slightly h igher than the actual o utside
temperature. Th is is caused by the heat
being radiated from the engine .
- On vehicles with Audi Nav igat ion sys­
tem *, the displays may differ from their
normal appearance during navigation .

The Malfunction Indicator Lamp (MIL) Ill in
the instrument cluster is part of the On-Board
Diagnostic (OBD II) system.
The warning/indicator light illuminates when
the ignition is switched on and goes o ut after
the engine starts and the idle has stabilized.
This indicates that the MIL is working proper­
ly.
If the light does not go out after the engine
is started, or illuminates whi le you are driv­
ing, a ma lfunction may exist in the engine sys­
tem. If the light illuminates, the catalytic con­
verter could be damaged.
Continue driving
with reduced power (avoid­
ing sustained high speeds and/or rapid accel­
erations) and have the condition corrected.
Contact your authorized Audi dealer .
If the light illuminates, the electronic speed limiter may also be malfunctioning. For more
information ¢
page 30, Electronic speed
limiter.
An improperly closed fuel filler cap may also
cause the MIL light to illuminate

On-Board D iagnostics monitors the compo­
nents of your emission control system . Each
monitored component in your engine system
has been ass igned a code. In case of a mal­
funct ion, the component will be identified
and the fault stored as a code in the control
module memory.
The MIL light may also illuminate if there is a
leak in the on-board fuel vapor recovery sys­
tem .
If the light illuminates after a refuelling,
stop the vehicle and make sure the fuel filler
cap is properly closed¢
