Fig. 189 Close-up:
proper positioning of
lifting jack
-Activate the parking brake so the vehicle will not roll
unintentionally.
- Shift into
1st gear on vehicles with manual transmission,
or move the
selector lever to the P position on vehicles
with automatic transmission.
- Position the jack below the door sill under the
mounting
point
that is closest to the wheel to be changed
=> page 274, fig. 188.
- Turn the
jack handle clockwise until the jack arm just fits
underneath the rib running along the underbody
=> &.
- Align the jack so that the jack arm claw => fig . 189 @ fits
snugly around the underbody rib and the movable base
plate @ sits flat on the ground. The base @ must be
vertical under the lifting point@.
- Wind the jack up further until the flat wheel comes off the
ground =>& .
Recesses at the front and rear of the underbody rib mark the proper
mounting locations for the jack ~
page 274, fig. 188. There is only
one
designated jack mounting point for each wheel. Do not apply
the jack anywhere else~& . The
jack should be positioned approximately 6 in. (15 cm) behind
the front wheel or 10 in. (25 cm) in front of the rear wheel.
An unstable surface under the jack can cause the vehicle to slip off
the jack. Always provide a firm base for the jack on the ground. If
necessary place a sturdy board or similar support under the jack. On
hard, slippery surfaces (such as tiles) use a rubber mat or similar to
prevent the jack from slipping ~& .
& WARNING
• You or your passengers could be injured while changing a
wheel if you do not follow safety precautions:
-Mounting the jack under the vehicle at any other place than
indicated above may damage the vehicle or may result in
personal injuries.
- A soft or unstable surface under the jack may cause the
vehicle to slip off the jack. Always provide a firm base for the
jack on the ground. If necessary, use a sturdy board under the
jack.
- 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

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 50.
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 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 for the repeated short circuit or overload tracked and
fixed. •

• 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

The battery is located in the front, in the engine compart­
ment on the driver's side. To reach the positive terminal,
remove the cover=>
page 238. The procedure described
below for connecting jumper cables is intended to provide
a jump start for your vehicle.
Preparatory measures
1. Do not jump start a frozen battery ! => & in "Sta rting
with jumper cables" on
page 285, => & in "General infor ­
mation of starting assistance" . Replace such a battery!
2. Otherwise apply the hand brake and shift into idle gear if
your vehicle has manual transmiss ion, and put the
selector lever into P position if your vehicle has auto ­
matic transmission.
3. For both veh ic les switch o ff a ll co nsumers and the igni ­
tion.
Connecting/disconnecting the jumper cable.
4. Connect one end of the red jumper cable to the positive
terminal

battery @=> (Din "General information of starting assis­
tance".
5. Connect the other end o f the red jumper cable to the
positive terminal
@ of th e boost er battery ®·
6. Connect one end of the black jumper cable, preferably at the ground point. Otherwise, connect it to the negat ive
terminal
0 of the booster battery ®·
7. Connect the other end of the black jumper cable to the
ground point (bolt head) © in your vehicle @.
8. Route the jumper cables so that they cannot catch in any
rotating parts in the engine compartment.
Starting the engine
9. Start the engine of the veh icle providing ass istance and
allow it to run at idle.
10. Now start the engine of the vehicle with the discharged
battery , wait for two to three minutes unt il the eng ine
" runs " smoothly.
11. If the engine does not start: Stop t rying after 10 seconds
and then try again after about 30 seconds.
12. In the vehicle that has received start assistance, turn on the heater blower and the rear window heating to elimi­
nate any voltage peaks when disconnecting. Driving lights must be switched off! .,

13. Disconnect the cable while the engine is running exactly
in
reverse order to that described in~ page 287,
11Connecting/disconnecting the jumper cable.11
• When
doing so, make sure that the cable cannot contact rotating engine parts.
14. Turn the heater blower and the rear window heating off again.
The battery is vented to the outside to prevent gases from entering
the vehicle interior.
Make sure that the jumper clamps are well connected with their
metal ports in full contact with the battery terminals .
& WARNING
To avoid serious personal injury and damage to the vehicle, heed
all warnings and instructions of the jumper cable manufacturer. If
in doubt, call for road service.
• Jumper cables must be long enough so that the vehicles do not
touch .
• When connecting jumper cables, make sure that they cannot
get caught in any moving parts in the engine compartment.
• Before you check anything in the engine compartment, always
read and heed all WARNINGS =>
page 215, "Engine compartment" .
0 Note
Improperly connected jumper cables can damage or destroy the
generator.
• Do not use the battery negative terminal for jump starting or a
malfunction could occur in the vehicle electrical system.
• Always connect POSITIVE(+) to POSITIVE(+), and NEGATIVE( -) to
NEGATIVE (-l terminal. •
Check that all screw plugs on the battery cells are screwed in
firmly. If not, tighten plugs prior to connecting clamp on negative battery terminal.
• Please note that the procedure for connecting a jumper cable as
described above applies specifically to the case of your vehicle
being jump started. When you are giving a jump start to another
vehicle, do
not connect the minus(-) cable to the minus 1-l terminal
on the discharged battery@=>
page 287, fig. 196. Instead, securely
connect the minus(-) cable to either a massive metal component
that is firmly bolted to the engine block or to the engine block itself.
If the battery that is being charged does not vent to the outside,
escaping battery gas could ignite and explode! •
