• Before winter sets in, have the coolant checked to see if th e
coolant additive in your vehicle is sufficient to meet the climate
conditions . This is especially important if you live in a region where
the winter is extremely cold .
If necessary, increase the proportion of
coola nt additive to 60% .
• When adding coolant additive to your cooling system, remember:
- We recommend using only coolant additive Gl2++ (check the
label) for your vehicle . This coolant additive is available at autho
r iz ed Audi dealers. Other types of antifreeze can significantly
reduce corrosion protection . The resulting corrosion can cause
a
loss of coolant and serious engine damage.
• Do not add any type of radiator leak sealant to your vehicle's
eng ine coolant . Adding radiator repair fluid may adversely affect the
function and performance of your cooling system and could result in
damage not covered by yo ur New Vehicle Limited Warranty .•

Replacing a fuse
A problem in the electrical system may be caused by a
blown fuse.
Fig. 244 Instrument
panel left: Face cover
- Locate the fuse which belongs to the component which
failed.
- Switch off the ignition and the electrical component affected.
- Carefully pry the face cover
off the instrument panel using
a screwdriver => fig. 244 .
- Remove the plastic clip from its retainer in the face cover,
place it over the questionable fuse and remove the fuse.
- Replace a blown fuse (recognizable by the melted metal
strip inside) with a fuse of the
same amperage.
The individual circuits are protected by fuses. The fuse panels with
the fuses are located on the left and right front faces of the instru-
Vehicle OP-eration
ment panel behind a cover and in the right storage area in the
luggage compartment.
There is a plastic clip in the cover on the left side of the instrument
panel, which can be used to remove the fuses. You will also find a
label on both covers in the instrument panel with the fuse layout for
the corresponding fuse panel.
& 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 account 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 of the repeated short circuit or overload located and fixed.
Ii] Tips
You are well advised to keep a supply of spare fuses in your vehicle .
Fuses with the proper ampere ratings are available at your authorized
Audi dealer. •
