<=> page 29 0 if you
are going to use a spare tire which is different
from t he tires on your vehicle.
Afte r you change a ti re:
- Check the tire pressure on the spare immedi ­
ately after installation.
- Have the wheel bolt tightening torque
checked with a torque wrench as soon as pos­
sible by your authorized Audi dealer or a
qualified service station.
- With steel and alloy wheel rims, the wheel
bolts are correctly tightened at a torque of 90
ft lb (120 Nm).
- If you notice that the wheel bolts are corroded
and diff icult to turn while changing a tire,
they should be replaced before you check the
tightening torque .
Emergency assistance
-Replace the flat tire with a new one and have
it installed on your vehicle as soon as possi­
ble. Remount the wheel cover .
Until then , drive with extra care and at reduced
speeds.

Emerg ency assis ta nce
There are some restrictions on the use of the
spare tire. The spare tire has been designed spe­
cifically for your type of vehicle. Do not replace it
with the spare tire from another type of vehicle.
There are different types of spare tires availab le
depending on the equipment
c::> page 320.
Remo ving t he spare tire
• Lift the cargo floor by the plast ic handle
~fig. 283.
• Hook the hand le into the luggage compartment
seal.
• Turn the handwhee l counter-clockwise and re-
move it.
• Remove the spare tire.
Sn ow c hain s
For technica l reasons, the use of snow chains on
the compact spare tire is not permitted.
If you have to drive with snow chains and a front
tire fa ils, mount the spare wheel in place of a
rear tire. Insta ll the snow cha ins on the rear tire
that you removed, and install that in p lace of the
front tire that failed.
A WARNING
-After installing a spare t ire, the tire pres­
sure must be checked as quickly as poss ible.
- Do not drive faster than 50 mph (80 km/h)
with a compact spare tire. Driving faster
than that increases the risk of an accident.
- To reduce the risk of an accident, avo id fu ll­
throttle acceleration, heavy braking, and
fast cornering with the compact spare t ire.
- To reduce the risk of an accident, never drive with more than one compact spare tire.
- Norma l summer or winter tires must not be
mounted on the compact spare wheel rim.
A WARNING
- Never use the spare tire if it is damaged or if
it is worn down to the tread wear indicators.
- If the spare tire is more than 6 years o ld,
use it only in an emergency and with ex­
treme caution and careful dr iving.
- The spare tire is intended on ly for tempora­
ry and short-term use. It should be replaced
320
as soon as possible with the normal whee l
and tire.
- For technical reasons, the use of tire chains
on the spare tire is not permitted. If it is
necessary to drive w ith tire chains, the spare
wheel must be mounted on the front axle in
the event of a flat in a rear t ire. The newly
ava ilable front wheel must then be installed
in place of the rear wheel w ith the flat tire.
Installing the tire chain befo re mounting
the wheel and tire is recommended.
- Loose items in the passenger compa rtment
can cause se rious personal injury during
ha rd braking or in an accident. Never store
the inflatable spare tire or jack and tools in
the passenger compartment .

Fuses a nd bul bs
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 diffi­
cult to replace vehicle light bulbs since in many
cases, other parts of the car must first be re­
moved before you are able to get to the bu lb .
This applies espec ially to the light bulbs in the
front of your car wh ich 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
m ust be correctly taken apa rt and then p roperly
put back together to help prevent breakage of
parts and long term damage from water that can
enter housings that have not been properly re­
sealed.
For your safety, we recommend that you have
your authorized Audi dealer replace any bu lbs for
you, since your dealer has the proper tools, the correct bulbs and the expertise.
G as di sc harg e l am ps (Xe non li ghts):
Due to the high electrical voltage, have the bulbs
replaced by a qua lified technic ian . Headlights
with Xenon light can be identified by the high
voltage sticker.
LED headlights* require no maintenance. Please
contact your authorized Aud i dealer if a bulb
needs to be replaced.
A WARNING
Contact w ith high-voltage components of the
electrical system and improper rep lacement
of gas discharge (Xenon) headlight bulbs can
cause serious personal injury and death.
- Xenon bulbs are pressurized and can ex­
plode when being changed.
- Changing Xenon lamps requires the special training, instructions and equipment.
- Only an a uthorized Audi dea ler or other
qualified workshop should change the bulbs
in gas discharge lamps .
326
A WARNING
-
There are parts with sharp edges on the open-
ings and on the bulb holders that can cause
serious cuts.
- If you are uncertain about what to do, have
the work performed by an authorized Audi
dealer or other qualified workshop. Ser ious
pe rsonal injury may resu lt from improperly
pe rformed wor k.
@ Tips
- If you must replace the light bulbs yourself,
always remember that the eng ine compart­
ment of any vehicle is a hazardous area to
work in. Always read and heed all WARN­ INGS
'* page 271.
-It is best to ask your authorized Audi dealer
whenever you need to change a bulb.

0 co .... N ,..... N .... 0 0 :c ' Emergency situations
General
This chapter is intended for trained emergency
crews and working personnel who have the nec­
essary tools and equipment to perform these
ope rations.
Starting by pushing or
towing
CD Note
Veh icles with an automatic transmission can­
not be started by pushing or towing.
Starting with jumper
cables
If necessary, the engine can be started by con­
necting it to the battery of another vehicle.
If the engine shou ld fail to start because of a dis ­
charged or weak battery, the battery can be con­
nected to the battery of
another vehicle, using a
pair of jumpe r cables to start the engine.
Jumper cables
Use only jumper cables of suffic iently large cross
section
to carry the starter current safely. Refer
to the manufacturer's specifications.
Use only jumper cables with
insulated term inal
clamps which are dis tinct ly marked:
plus (+) cable in most cases colored re d
minus( -) cable
in most cases colored black.
A WARNING
Batteries contain electricity, acid, and gas.
Any of these can cause very serious or fatal in­
jury. Follow the instructions below for safe
handling of your vehicle's battery.
- Always shield your eyes and avo id leaning
over the battery whenever poss ible.
- A dead battery can freeze at temperatures
around 32 °F (0 °C). If the vehicle battery is
frozen, you must thaw it before connecting
the jump start cab les. If you do not, this in-
Emergency situations
creases the risk of an explosion and chemi­
cal burns. After jump starting the vehicle,
drive to an authorized Aud i dealer or author­
ized Audi Service Facility immediately to
have the vehicle battery checked.
- Do not allow battery ac id to contact eyes or
skin . Flush any contacted area with water
immed iately.
- Improper use of a booster battery to start a
veh icle may cause an explosion .
- Veh icle batteries generate explosive gases.
Keep sparks, flame and lighted cigarettes
away from batter ies.
- 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 rat ing. The capacity (Ah) of
the booster battery should not be lower
than that of the discharged battery. Use of
batter ies of different voltage or substantial­
ly different "Ah" rating may cause an exp lo­
sion 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 . T he battery case may have be weak­
ened.
- Use of batteries of different voltage or sub­
stantially different capacity (Ah) rating may
cause an exp losion and injury . The capacity
(Ah) of the booster battery should not be
lower than that of the discharged battery.
- Before you check anything in the engine
compartment, always read and heed all
WARNINGS
qpage 271.
CD Note
-App lying a higher voltage booster battery
wi ll ca use expensive damage to sensitive
electronic components, such as control
units, relays, radio, etc.
- There must be no electrical contact between
the vehicles as otherwise current could al­
ready start to flow as soon as the positive
(+) terminals are connected.
327

Emergency situations
@ Tips
The discharged battery must be properly con­
nected to the vehicle's electrical system .
When jump starting or charging the battery,
never connect the negative ground cable to
the battery negative post because the battery
manager system must be able to detect the
battery's state of charge. Always connect the
negat ive ground cable to the negative ground
pos t of the battery manager control unit.
Using the jump start
cable
Both jump start cables must be connected in the
correct order!

procedure after 10 seconds and then repeat it
after approximately 30 seconds .
... Remove the cables whe n the engi nes are run­
ning. Remove them in reverse order from the
way they were installed.
" Close the cover on the positive terminal.
The battery is vented to the outside to prevent
gases from enter ing the vehicle interior. Make
sure that the jumper clamps are well connected
with their
metal parts in full contact with the
battery terminals .
A WARNING
