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 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 .
- Work with due care when handling the
high-vo ltage sect ion of gas discharge
(xenon) lamps. Failing to do so could re­
sult in death or serious injury!
BRAKE LIGHT!<@> Brake light defective
In case of a malfunction or component fail-
ure, the symbol (USA models)/
tlJ (Canada models) can appear. The follow­
ing electrical components should be checked,
repaired or replaced , as necessary:
- Brake light bulbs
- All wir ing con nections
- Brake light switch
Contact your authori zed Audi dea ler for assis­
tance if necessary.
(D Tips

(D Note
To prevent possible damage to the heating
elements, do not kneel on the seats or ap­
ply a heavy load to relatively small areas of
the seat.
Engine preheater
Applies to vehicles: with engine p reheate r
Use of the engine pre heater is recommended
when the ambient temperature is below
-5 °F
(-20 °C) .
Fig. 100 In t he l eft fron t bump er: en gine preheater
co nn ect ion socket
The engine preheater slowly w arms the en­
gine coolant using a heating element when
the vehicle is parked. The included cable
1>
must be connected to a 120 Volt Ground Fault
Circuit (GFI) protected outlet that is protected
from water (in your garage, for instance).
When the coolant is preheated, the engine
reaches its operating temperature more quick­
ly and will use less fuel and produce fewer
polluting emissions during the warm-up
phase.
Preheating the engine can take up to 3 hours
depending on the temperature outside.
Connecting the engine preheater
- Only use the cable provided.
-All cables and connectors that are used
must not be damaged
¢ .&.­
-Open the cover Q fig. 100 @.
l) Th e cabl e is de live red w it h veh icles i n Canada a s
s tandard e quipmen t. The cable c an be o btain ed fro m
an a uth orize d Au di d ea le r fo r veh icl es in the USA.
- Plug the connecting cable into the socket @
Q.ii_.
-Connect the connecting cable to the power
cord.
- Attach the extensions cord to the connector
cable. Always use a 12 gauge or heavier
heavy -duty extension cord that can be prop ­
erly grounded to a three-prong Ground Fault
Circuit (GFI) wall outlet and is not longer
than 100
ft (30 meters).
- Always plug the preheate r into an 120 Volt
Ground Fault Circuit (GFI) wall outlet that is
properly protected against rain and other
moisture. Never plug the preheater into a
normal outlet regardless of whether it is
grounded or not .
- Always disconnect the connecting cable and
close the cover
Q fig . 100 @ before starting
the engine.
_&. WARNING
-
Using incorrect or damaged outlet and
power cords, using electrical accessories
incorrectly or ignoring safety precautions
can lead to short circuits, accidents, inju­ ries and life-threatening electric shocks.
- Always plug the preheater into a
120 Volt Ground Fault Circuit (GFI) wall
outlet that is properly protected against
rain and other moisture.
- Always check the fuse protection of the
120 Volt power source before using the
connecting cable .
- Always use a 12 gauge or heavier heavy­
duty extension cord that can be properly
grounded to a three-prong GFI outlet .
The extension cord must not be longer
than 100
ft (30 meters).
- Always connect the cable to a 120 Volt
outlet that is grounded and protected
from water .
- Check the cable for damage before every
use . Never use a damaged cable.

Bulbs
Replacing light bulbs
For your safety, we recommend that you have
your authorized Audi dealer replace burned
out bulbs for you.
It is becoming increasingly more and more
difficult to replace vehicle light bulbs since in
many cases, other parts of the car must first
be removed before you are able to get to the
bulb. This applies especially to the light bulbs
in the front of your ca r which you can only
reach through the engine compartment.
Sheet metal and bulb holders can have sharp
edges that can cause serious cuts, and parts
must be cor rectly taken apart and then prop­
erly put back together to help prevent break­
age of parts and long term damage from wa ­
ter that can enter housings that have not been
properly re sea led.
For your safety, we recommend that you have
your authorized Audi dea ler replace any bulbs
for you, since your dealer has the proper tools,
the correct bulbs and the expertise.
Gas discharge lamp s (Xenon lights)*:
Due to the high e lectr ica l voltage, have the
bulbs replaced by a qualified techn ic ian.
Head lights with Xenon light can be identified
by the high voltage sticker.
_& WARNING ~
Contact with high-vo ltage components of
the electrical system and improper re­
placement of gas discharge (Xenon) head­
light bulbs can cause serious personal in­
jury and death.
- Xenon bulbs are pressur ized and can ex­
plode when being changed.
- Changing Xenon lamps requires the spe­
cial tra ining, instructions and equip­
ment.
- On ly an authorized Audi dealer or other
qualified workshop should change the bulbs in gas discharge lamps .
