16 Instrum ent s and w arn ing /indic ato r light s
immediately by your authorized Audi
dealer or a qualified workshop. Drive
slowly and avoid sudden, hard brake ap­ plication.
- Canada models: If both, the brake warn­
ing light . and the ABS warning light
Ii] come on at the same time, the rear
wheels could lock up first under hard braking. Lock-up of the rear wheel brakes
can cause loss of vehicle control and an
acc ident. Have your vehicle repaired im­
med iately by your authorized Audi dealer
or a qualified workshop. Drive slowly and avoid sudden, hard brake application
- If the brake warning/indicator light does not go out after a few seconds and the
park ing brake re leased, or lights up while
you are driving, the fluid level in the brake flu id reservo ir is too low. If you be­
lieve that it is safe to do so, proceed im­
med iately at low speed to the nearest
authorized Audi dealer or qualified work­
shop and have the bra ke system inspect­
ed.
- Always keep in m ind that afte r several
brake applicat ions, you will need g reater
pressure on the b rake peda l to stop your
vehicle. Do not re ly on strained brakes to
respond with maxim um stopping power
in critical situations . You must allow for
increased brak ing distances. The extra
distance used up by fad ing brakes could
lead to an acc ident.
~ / ! .!r Safety systems
The I (USA models)/ . (Canada mode ls) in­
d icator light monitors the safety systems e.g.
a irbags, pretensioners a nd illum inates for a
few seconds each time you switc h the ign ition
on.
If the
I (USA models)/ . (Canada models)
indicator light does not go out, or if it illumi­
nates w hile you are driv ing, or if it sta rts to
b lin k, then there is a ma lf u nction somewhere
in the system. If the light does not illuminate
when you switch on the ignition, this also
means there is a ma lfunction.
A WARNING
If you have a ma lfunction in the safety sys­
tems, contact your authorized Audi dea ler
i mmediately. Otherwise the safety sys­
tems may not work properly in an acc i­
dent.
~ Safety belt warning light
App lies to veh icles : w ith safe ty belt warni ng lig h t
The warning light is a reminder to fasten
safety belts .
The warning lig ht . comes on for a few sec­
onds after the ignition is sw itched on as a re ­
minder to fasten your safety belt .
Additional information on safety belts
r::> page 113.
D Generator '
This warning/indicator light detects a mal ­
function in the generator or in the vehicle 's
electrical system.
The . warning/indicator light i llum inates
when you switch on the ignition and must go
out after the eng ine has started.
If the . warning/indicator light illuminates
whi le you are driving, you sho uld contact your
authorized Aud i dea ler. Since the vehicle bat­
tery is discharging, you shou ld sw itch
off any
unnecessary electr ica l consumers (for exam ­
ple, the air conditioner) .
~ Engine oil pressure
The red engine oil pressure warning symbol
requires immediate service or repair .
If the . symbo l appears in the d isplay and
flashes, the o il pressure is too low . In add ition
to the symbol, the following message a lso ap­
pears in the display:
Switch off engine! Oil pre ssure is too low
.. Pull off the road and stop the vehicle.
.. Shut the engine down.
.. Check the engine oil leve l¢
page 200.

Instruments and warning/indicator lights 21
If the message does not turn off, have your
authorized Audi dealer or qualified workshop
correct the malfunction .
Bil Fuel supply too low
When the (I symbol illuminates, this means
there are about 2.6 gallons (10 liters) of fuel left in the fuel tank. Time to refuel!
Qpage 191.
If the symbol lights up, even when there is
ample fuel in the tank, and the text
Tank sys­
tem malfunction! Please contact workshop
appears in the display, there is a fault in the
system. Contact a qualified workshop to have
the fault rectified.
Q Windshield washer fluid level too low
If the I! symbol illuminates, add windshield
washer fluid to the washer system
Q page211.
~ Defective light bulb warning
The defective light bulb warning tells you
when a vehicle light bulb hos become defec­
tive .
If a defective bulb has been detected by the
system or a light bu lb burns out , the ~ sym­
bol with a message appears in the disp lay to
tell you which bu lb is burnt out and where it is
located. For example:
Rear left turn signal
After 5 seconds, the message disappears . If
you want to recall the message into the dis­
p lay, press the C H ECK button
Q page 10,
fig. 3(?) .
There are three reasons why the defective
bulb message wo uld app ear in the display:
- T he light bulb has burnt out
Q page 246 .
-The fuse is "blown" c> page 243, Replacing
fuses .
-The w ire connection to the light bulb is de­
fective. Have the
bulb replaced or the connection re­
paired by your authorized Audi Service depart­
ment .
_& WARNING
- Light bulbs are pressurized and could ex­
plode wh ile they are being changed caus­
ing serious pe rsonal injury .

high-vo ltage sect ion of gas discharge
(xenon) lamps. Failing to do so could re­
sult in death or serious injury!

ure, the symbol (USA models)/

ing electrical components should be checked,
repaired or replaced , as necessary:

A WARNING
- Never rely exclusively on the outside

road surface is icy or not . Keep in mind
that road surfaces, especially bridges
and overpasses, could be ice covered and
slippery even at an outside temperature
above 41 °F (+S °C).
- Always remember, even if the "snow­
f lake" symbo l (ice warning) does not ap­
pear in the display, black ice could be on
the road.
- Always reduce your speed and drive with
special care in cold weather conditions
when the chance of encountering icy
road surfaces increases.
(D 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 h igher than the actual outside .,,.

On-Board Diagnostics
Fig. 9 Locat ion of Data Link Connector (DLC)
On-Boa rd Diagnostics monitors the compo­
nents of your em iss ion control system. Each
controlled component in your engine system
has been assigned a code . In case of a mal ­
function, the component wi ll be identified
and the fault stored as a code in the control
module memory.
The MIL lamp may a lso illuminate if there is a
leak in the on-board fuel vapor recovery sys­
tem. If the light illuminates after a refuelling,
pull off the road and stop the vehicle, then
check that the fuel filler cap is properly closed
c:> page 192.
In order to make an accurate diagnosis, the
stored data can only be displayed using spe ­

for 080) .
In order to connect the special diagnostic
equipment, push the plug into the Data Link
Connector (DLC). The DLC is located to the
right of the engine hood release lever
