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 nec­
essary p lace a sturdy board or simi lar support
under the jack. On
hard, slippery surfaces
(such as tiles) use a rubber mat or similar to
prevent the jack from slipping ¢
.&,.
A WARNING
--You or your passengers cou ld be injured
while changing a wheel if you do not fol­
low safety precautions:
- Position the vehicle jack on ly at the
designated lifting points and align the
jack. Otherwise, the vehicle jack could

slip and cause an injury if it does not
have sufficient hold on the veh icle.
- 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 u nti l yo u are
sure the jack is sec urely engaged .
- Pa ssenge rs must not remai n in the ve­
h icle when it is jacked up.

212 What do I do now?
When removing or installing the wheel,
the rim could hit the brake rotor and dam­
age the rotor. Work carefully and have a
second person help you.
Never use the hexagonal socket in the han ­
dle of the screwdriver to loosen or t ighten
the wheel bolts.
- Pull the reversible b lade from the screw­
driver before yo u use the hexagonal
socket in the handle to turn the whee l
bo lts.
- When mounting tires with
unid irectional
tread design
make sure the tread pat­
tern is pointed the r ight way
~page 212.
- The wheel bolts should be clea n and easy
to tu rn . Check for d irt and corrosion on
the mat ing su rfaces of both th e whee l
and the h ub. Remove a ll dirt from these
su rfaces before remo unti ng the wheel.
Notes on wheel change
Pl ease read the informa tion ~ page 192, New
tires and replacing tires and wheels,
if you are
going to use a spare t ire which is different
from the tires on your vehicle.
After you change a tire :
-Check the tire pressure on the spare imme­
diately after mounting .
- Have the wheel bolt tightening torque
che ck e d with a torqu e wrench a s soon as
possible b y your auth orized Audi dealer or
a qualified ser vice station .
- With steel and alloy wheel rims , the wheel
bolts are correctly tightened at a torque of
90 ft lb (1 20 Nm ).
- If y ou notice while changing a tire that the
wheel bolts are co rroded and difficult to
turn , then the y should be repl aced befo re
you check the t ightening torque . -
Repla ce the flat ti re with a new one and
have it installed on your veh icle a s soon as
possible. Remount the wheel cove r.
Until then , dr ive with extra care and at re­
duced speed s.
_& WARNING
-
- If you are going to eq uip your vehicle
wit h tires or rims which differ from those
which were factory installed, then be
sure to read the information
9 page 192,
New tires and replacing tires and
wheels.
- Always store the tools secu rely i n lug­
gage compartment. Othe rwise, in a n ac­
cident or s udden maneuver they cou ld fly
forwa rd, causi ng injury to passengers in
the vehicle.
Tires with unidirectional tread design
Tires with unidirectional tread design must be
mounted with their tread pattern pointed the
right direction.
A un idirectional tire can be identified by ar­
rows on the sid ewall ,
which point in the direc­
tion of the rota tion. Yo u m ust follow the
specified direction of rota tion. This is ne ces sa ­
r y in order fo r these tires to develop t heir op ­
timum character istics regard ing grip, road
noise, wear, and hydrop laning.

fuses in your vehicle. Fuses with the proper
ampere ratings are available at your author ­
ized Audi dealer.
A WARNING
-
Do not repair fuses and never replace a
b lown fuse with one that has a higher amp
rating. This can cause damage to the elec­
trica l system and a fire.
(D Note
If a new fuse burns out again after short ly
have you have installed it, have the electri­
ca l system checked by your authorized

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 . Th is appl ies especially to the l ight bulbs
in the front of your car which you can only
reach through the engine compartment.
Sheet metal and bulb holders can have sharp
edges that can cause ser ious cuts, and parts
must be co rrectly taken apart and then prop­
e rly 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 resealed.
For your safety, we recommend that you have
your author ized Audi dealer replace any bulbs
for you, since your dealer has the proper tools,
the correct bu lbs and the expertise.
Gas disc harg e la mps (X enon l ig ht s}*:
Due to the high electrical voltage, have the
bulbs replaced by a qualified technician.
Headlights with Xenon light can be identified
by the high voltage sticker.
A WARNING
Contact with high-voltage 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 pressurized and can ex­
plode when being changed. -
Changing Xenon lamps requires the spe­
cial tra ining, instructions and equip­
ment.
- Only an authorized Audi dealer or other
qualified workshop should change the
bulbs in gas discharge lamps.
A WARNING
=
There are parts with sharp edges on the
openings and on the bulb holders that can
cause ser ious cuts.
- If you are uncertain about what to do,
have the work performed by an author­
ized Audi dealer or other qualified work­
shop. Serious personal injury may result
from improperly performed work.
@ Tips
- If you must replace the light bulbs your­
self, a lways remember that the eng ine
compartment of any vehicle is a hazard­
ous area to work in. A lways read and
heed all WARNINGS
¢page 165, Work­
ing in the engine compartment¢.&..
-It is best to ask your authorized Audi
dealer whenever yo u need to change a
bulb .

Emergency situations
General
This chapter is intended for trained emer­
gency crews and working personnel who
have the necessary tools and equipment to
perform these operations.
Starting by pushing or
towing
(D Note
Vehicles with an automatic transmission
cannot be started by pushing or towing .
Starting with jumper
cables
If necessary, the engine can be started by
connecting it to the battery of another vehi­
cle.
If the engine should fail to start because of a
discharged or weak battery, the battery can be
connected to the battery of
another vehicle,
using a
pair of jumper cables to start the en­
g ine.
Jumper cables
Use only jumper cables of sufficiently
largecross section to safely carry the starter
current. Refer to the manufacturer's specifica­
tions.
Use only jumper cables which have
insulated
termina l clamps and are properly marked for
distinction :
plus(+) cable in most cases colored red
minus(-) cable
in most cases colored black.
_& WARNING
Batteries contain electricity, acid, and gas.
Any of these can cause very serious or fatal
injury. Follow the instructions below for
safe handling of your vehicle's battery.
- Always shield you r eyes and avoid lean­
ing over the battery whenever possible.
Emergency situations 21 7
-A discharged battery can already freeze
at temperatures just below 32 °F (0 °C).
Before connect ing a jumper cable, the
frozen battery must be thawed com­
pletely, otherwise it could explode .
- 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 batter ies generate explosive gas­
es. Keep sparks, flame and lighted c iga­
rettes away from batteries.
- Do not try to jump start any veh icle w ith
a low ac id 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 bat­
tery. Use of batteries of diff erent voltage
or substantially different "Ah" rat ing
may cause an exp losion and personal in­
jury.
- Never charge a frozen battery. Gas trap­
ped 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) rat ­
ing may cause an exp losion and injury .
The ca pa city (Ah) of the booster battery
should not be lower than that of the dis­
charged battery.
- Before you check anything in the engine
compartment, always read and heed all
WARNINGS
c::;,page 165, Working in the
engine compartment.
(D Note
- App lying a higher voltage booster bat­
tery will cause expensive damage to sen­
sit ive electronic components, such as
control units, relays, rad io, etc .
- There must be no electrical contact be­
tween the vehicles as otherwise current
could already start to flow as soon as the
posit ive(+) terminals are connected. ..,. •

218 Emergency situations
@ Tips
The discharged battery must be properly
connected to the vehicle's electrical sys­
tem.
Use of jumper cables
Make sure to connect the jumper coble
clomps in exactly the order described below!
Fig. 165 Engine compart ment: Co nnectors for jumper
cables and charger

hicle: @discharged veh icle batte ry,® booste r battery
The procedure described below for connecting
jumper cables is intended to provide a jump
start for your veh icle.
Preparatory measures
1. Do not jump start a frozen battery! Re­
place such a battery!
2 . Otherwise apply the hand brake and put
the selector lever into P position.
3. For both vehicles switch off all consumers
and the ign ition.
Connecting/disconnecting the jumper
cable .
4. Connect one end of the red jumper cable
on the
jump start bolt@q fig. 166
(Bolts under red cover = "positive") of the
vehicle to be started @.
5. Connect the other end of the red jumper
cable to the positive terminal @of the
booster battery @.
6. Connect one end of the black jumper ca­
ble to the negat ive terminal @of the
booster battery @.
7. Connect the other end of the black jumper
cable to the negative terminal (bolt head)
@ in the external start ing point @ of
your vehicle.
8. Route the jumper cables so that they can­
not catch in any rotating parts in the en­
gine compartment.
Starting the engine
9. Start the engine of the vehicle providing
assistance and allow it to run at id le .
10. Now start the engine of the vehicle with
the discharged battery, wait for two to
three minutes until the engine "runs"
smoothly.
11. If the eng ine does not start: Stop try ing
after 10 seconds and then try again after
about 30 seconds.
12. In the vehicle that has received start as­
sistance, turn on the heater blower and
the rear window heating to elim inate any
vo ltage peaks when disconnecting . Driv­
ing lights must be switched off!
13 . Disconnect the cable while the engine is
running exactly in
reverse order to that

page 218, Connecting/dis­
connecting the jumper coble ..
When do­
ing so, make sure that the cable cannot
contact rotating eng ine parts.
14. Close the cover on the positive terminal.
The battery is vented to the outside to prevent
gases from entering the vehicle inter ior. Make
sure that the jumper clamps are well connect­
ed with their
metal parts in full contact with
the battery terminals.
A WARNING ~
To avoid serious personal injury and dam-
age to the vehicle, heed all warnings and
