Auto Check Control
Some functions and vehicle components are
scanned for their operating status when you
switch the ignition on and while you are driving. Malfunctions or required service procedures are
signaled audibly and indicated by red and yellow
illum inated symbols and reminders in the dis­
play.
A WARNING
--
- Never rely exclus ively on the outside tem­
pe rature display to determine if a road sur­
face is icy or not. Keep in m ind 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 remember, even if the "snowflake"
symbol (ice warning) does not appear in the
display, black ice could be on the road.
- Always reduce your speed and dr ive 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 driv­
ing at a very low speed, the temperature
shown in the disp lay might be slightly higher
than the actual outside temperature. This is
caused by the heat being radiated from the
engine.

Driver information system
In addition, you can determine what information
from the trip computer should be shown in the instrument cluster disp lay . If one of the pieces of
driver information is turned
Off , that driver infor­
mation will not be shown in the display. The in­
formation will continue to be calculated by the
tr ip computer and can be turned back
On at any
time .
(D Tips
-This function is not available on all veh icles.
- The driving information in the efficiency
program is also reset to zero with the sin­
gle-trip memory .
Gearshift Indicator
Appl ies to ve hicles: w ith manu al transmiss ion an d ge arshi ft
i n di cato r
This indicator can help conserve fuel.
Fig. 12 Display: Gearshift indicator
In order to become familiar with the gearshift in­
d ictor, at firs t just drive the way you are used to.
If the current gear - and the driving situation -is
not the best one for conserving fuel, then the in­
d icator will display the recommended gear. The
display shows the current gear and the gear that
is recommended
c>fig. 12.
-Upshifting The display will light up to the right
of the gear currently selected if it is recom­
mending a higher gear.
-Downshifting: The display will light up to the
left of the gear current ly selected if it is recom­
mending a lower gear.
Sometimes the indicator will recommend skip­
ping a gear (3
> 5).
26
If there is no gearshift recommendation, then
just drive in the appropriate gear for conserving
fuel.
(D Note
This indicator can help you conserve fuel. This
indicator is not meant to show you which gear
you should a lways be in in all driving situa­
tions. Somet imes, in situations such as pass­
i ng, driving through mountains or when tow­
i ng a tra iler, there won't be any gearshift rec­
ommendat ion.
@ Tips
The display does not light up when the clutch
pedal is be ing depressed .
Efficiency program
Description
Applies to vehicles : wi th trip co mpute r with eff ic ie n cy pro­
gram

repeatedly until the efficiency program appears
in the display .
The efficiency program can help you to use less
fuel. It evaluates driving information in reference
to fuel consumpt ion and shows other equipment
i nfluencing consumption as well as shift recom­
mendat ions. Fuel economy messages
c>
page 28 provide tips for efficient driv ing.
The eff ic iency program uses distance and con­
sumption data from trip computer
1. If the data
are deleted in the efficiency program, those val­
ues are also reset in trip computer

• In the efficiency program, press the function
selection switch¢
page 25, fig. 11@ repeat­
edly until the enhanced shift indicator appears
in the display.
The efficiency program also has an enhanced
shift ind icator. This enhanced shift indicator fol­
lows the same concept as the "standard" shift in­
dicator¢
page 26. The selected and the recom­
mended gears are highlighted in colors like a
traffic light .
The color of the circle indicates if the most suita­ b le gear is engaged or if you should shift up or
down.
Green circle w ithout or No gear or the most
with a gear suitable gear is engag-
ed

gear
Red circle Shift up two gears
(D Note
This enhanced shift indicator can help you
conserve fuel. It is not designed to recom­
mend the correct gear in all dr iving situa­
tions . Only the dr iver can decide which gear is
correct in certain dr iving situations such as
when passing another veh icle, dr iving on hill s
or towing a trailer.

(D Tips
-The enhanced shift indicator display is dif­
ferent in vehicles with a monochrome dis­
play.
- The "standard" shift indicator* disappears
when the enhanced shift indicator is dis­
played.

Other equipment that is currently affecting fuel
consumption is listed in the eff ic iency program.
T he display shows up to three other items of
equipment @. T he equipment using the most
fuel is listed first. If more than three items using
fuel are switched on, the equipment that is cur­ rently using the most fuel is displayed.
A scale @also shows the current total consump­

taining its value. Even if the mileage driven
is low, the maximum period of one year
from one service to the next must not be ex­

On Board Diagnostic
System (OBD)
Malfunction Indicator Lamp (MIL)
The Malfunction Indicator Lamp (MIL) ¢..ift in the
instrument cluster is part of the On-Board Diag­
nostic (OBD II) system .
The warning/indicator light illuminates when the
ignition is switched on and goes out after the en­
gine starts and the idle has stabilized. This indi­
cates that the MIL is working properly .
If the light does not go out after the engine is
started, or illuminates while you are driving, a malfunction may exist in the engine system.
If
the light illuminates, the catalytic converter
could be damaged.
Continue driving
with reduced power (avoiding
sustained high speeds and/or rapid accelera­
tions) and have the condition corrected. Contact
your authorized Audi dealer.
If the light illuminates, the electronic speed lim­iter may also be malfunctioning. For more infor­
mation
¢ page 29, Electronic speed limiter.
An improperly closed fuel filler cap may also
cause the MIL light to illuminate ¢
page 200.
Driver in forma tion system
On-Board Diagnostics
Fig. 17 Loca tion of Data Link Connector (DLC)
On-Board Diagnostics monitors the components
of your emission control system. Each monitored
component in your engine system has been as­
s igned a code. In case of a malfunction, the com­
ponent 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 system.
If the light illuminates after a refueling, stop the
vehicle and make sure the fuel f iller cap is prop­
erly closed
¢ page 200.
In order to make an accurate diagnosis, the stor­
ed data can only be displayed using special diag­
nostic equipment (gener ic scan tool for OBD).
In order to connect the special d iagnost ic equip­
ment, push the p lug into the Data L ink Connector
(DLC). The DLC is located to the right of the hood
release
¢ fig. 17.
Your authorized Audi dealer or qualified work­
shop can interpret the code and perform the nec­
essary repair.
.&, WARNING
Do not use the diagnostic connector for per­
sonal use. Incorrect usage can cause malfunc­
tions, which can increase the risk of a co lli­
sion!
Electronic speed limiter
Your vehicle may be factory equipped with tires
that are rated for a maximum speed of 130 mph (210 km/h). This is may be less than the maxi­
mum speed of your vehicle . To reduce the risk of .,.
29

Driver information s ystem
sudden tire failure and loss of contro l if the vehi­
cle is operated at excessive speeds, your vehicle has an electronic speed limiter . The e lectronic
speed limiter prevents your veh icle from go ing
faster than the t ire speed rating. For more infor­
mat io n
¢ page 217 .
If the engine contro l unit receives faulty vehicle

tact the nearest author ized Audi dealer for assis ­
tance .
A WARNING
Always observe the posted speed limits and
adjust you r speed to s uit prevailing road, traf­
fic and we athe r con ditions. Never drive you r
vehicle fas ter than the maximum speed rat ing
of the tires installed.
