- On hard, slippery surface (such as tiles ) use a rubber mat or
similar to prevent the jack from slipping .
• To help prevent injury to yourself and your passengers:
-Do not raise the vehicle until you are sure the jack is securely
engaged.
- Passengers must not remain in the vehicle when it is jacked
up.
- Make sure that passengers wait
in a safe place away from
the vehicle and well away from the roadway and traffic .
- Make sure jack position is correct, adjust as necessary and
then continue to rai se the jack. •

• T he wheel bolts should be clean and easy to turn . Check for dirt
and corrosion on the mating surfaces of bo th the wheel and the
hub. Remove all dirt from these surfaces before remounting the
whee l.•
Tires with unidirectional tread design
Tires with unidirectional tread design must be mounted
with their tread pattern pointed in the right direction.
Using a spar e tir e with a tread pa ttern intended for u se
in a sp ecific direc tion
When using a spare tire with a tread pattern intended for use in a
specific direction , p lease note the following:
• T he direction of rotation is marked by an arrow on the sid e of the
tire .
• I f the spare tire has to be installed in the incorrec t direction in the
event of a flat tire , use the spare tire on ly temporarily since the tire
wi ll not be ab le to achieve its optimum performance characteristics
with regard to aquap laning, noise and wear .
• We recommend that particula r atten tion be pa id to this fact
dur ing wet weather and that you adjust your speed to match road
conditions.
• Replace the flat tire with a new one and have it installed on your
vehicle as soon as possible to restore the handling advantages of a p roper ly pointed d irection -dependent t ire. •
Notes on wheel change
Please read the information=> page 255, "New tires and replacing
tires and wheels" if you are going to use a spare tire which is
different from the tires on your veh ic le.
Aft er you change a tire :
• Che ck the ti re pre ss ure on the spare immed iately aft er
mounting .
• Have the wheel b olt t ight en ing to rque checked with a torque
wrench a s soon a s po ssible by your authorized Audi dea ler or a
q u alified service stat ion .
• On steel and a lloy wheel rims , the wheel bolt s are correctly tight­
ened with a t orque of 90 ft lb (1 2 0 Nm l.
• If you noti ce w hile changing a tire that the wheel bolt s are
c o rroded and d iff ic ult to turn , then they should be repla ced befo re
you check the tightening torque.
• Repl ace the fl at t ir e w ith a new one and hav e it installed o n your
vehicle as soon as pos sib le . Remount the wheel cover .
Until then , drive wi th ext ra care and at redu ced speeds.

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. •

Emergency situations
General
This chapter is intended for trained emergency crews and working
pe rsonnel who have the necessary tools and equ ipment to perform
these operations. •
Starting by pushing or towing
(D Note
Vehicles with an automatic transmis sion cannot be started by
push ing or towing . •
Starting with jumper cables
Ju mpe r cabl e: Note the man ufa ct ure r's in for matio n.
If the battery is discharged, another veh icle can provide starting
assistance. For this you require a jumper cable. Both batteries must
h ave t he same vo ltage (V) and a s im ilar capacity (Ah).
Jumper cables
Use
only jumper cables of sufficiently large cross section to safely
car ry the starter current . Refer to the manufactu rer's specifications.
Use only j um per ca bles with
isolated term in al cl am ps and pr operly
marked for distinction :
plus
(+) cable in mo st c ases c olored red
minus( -) cable i n most cas es co lor ed black .
& WARNING
Batteries contain electricity, acid , and gas. Any of the se can cause
very ser ious or fatal injury . Follow the instructions below for safe
handling of your vehicle 's battery .
• Always shield your eyes and avoid leaning over the battery
whenever possible .
• A discharged battery can already freeze at temperatures just
below 32 °F (0 °C l. Never attempt to provide starting assistance on
a frozen or thawed out battery- Danger of explosion and chemical
burns! Replace a battery if it has been frozen.
• Do not allow battery acid to contact eyes or skin. Flush any
contacted area with water immediately .
• Improper use of a booster battery to start a vehicle may cause
an explosion .
• Vehicle batteries generate explosive gases . Keep sparks, flame
and lighted cigarettes away from batteries .
• Do not try to jump start any vehicle with a low acid level in the
battery .
• The voltage of the booster battery must also have a 12 -Volt
rating . The capacity (Ah ) of the booster battery should not be
lower than that of the discharged battery . Use of batteries of
different voltage or substantially different "Ah " rating may cause
an explosion and personal injury .
• Never charge a frozen battery . Gas trapped in the ice may cause
an explosion.
• Never charge or use a battery that has been frozen . The battery
case may have be weakened .
• Use of batter ies of different voltage or substantially different
capacity (Ah) rating may cau se an e xplosion and inju ry . The
c apacity (Ah ) of the booster battery should not be lower than that
of the discharged battery. .,.
