Defective light bulb warning ~
The defective light bulb warning tells you when a vehicle
light bulb has become defective.
If a defective bulb has been detected by the system or a light bulb
burns out, the ' symbol with a message appears in the display to

gas discharge (xenon) lamps. Failing to do so could result in death
or serious injury! •

_________________________________________________ F_ u_ s_ e_s _ a_n _d_ b_ u _ lb_ s _ __._
The various electrical circuits are protected by fuses. The fuses are
clustered in a centralized unit. The unit is located behind the face
panel at the end of the instrument panel. The crank for operating
the sunroof in case of a power failure is a lso stored behind the face
panel
~ page 49.
Two spare fuses and a sticker identifying the fuses are located on
the inside of the fuse box cover.
You are well advised to keep a supply of spare fuses in your vehicle .
Fuses with the proper ampere ratings are available at your autho ­
rized Audi dealer.
& WARNING
Never replace a fuse with one that has a higher amperage rating.
• A fuse with a too high amperage could damage the electrical
part and cause a fire .
0 Note
• On no accoun t should fuses be repaired (e.g . patched up with tin
foil or wire) as this may cause serious damage elsewhere in the elec­
trical circuit or cause fire.
• If a fuse blows repeatedly, do not keep replacing it. Instead, have
the cause for the repeated short circuit or overload tracked and
fixed. •
