Emergency assistance
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 available
depending on the equipment
c::> page 320.
Removing the spare tire
• Lift the cargo floor by the plast ic ha ndle
c::> fig. 282.
• Hook the hand le into the luggage compartment
weathe r strip.
• Turn the handwheel counter-clockwise and re-
move it.
• Remove the spare tire.
Snow chains
For technical reasons, the use of snow chains on
the compact spare tire is not permitted.
If you have to drive w ith snow chains and a front
tire fails , mount the spare t ire in place of a rear
tire . Install the snow chains on the rear tire that
you removed, and install that in place of the
front tire that failed.
A WARNING
-After installing a spare tire, the tire pres­ sure must be checked as quickly as possible.
- 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, avoid full­
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 old, use it only in an emergency and with ex­
treme caution and careful dr iving .
- The spare tire is intended only 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 with tire chains, the spare
wheel must be mounted on the front axle in
the event of a flat in a rear tire . 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 before mounting
the wheel and tire is recommended.
- Loose items in the passenger compartment
can cause serious personal injury during
hard braking or in an accident. Never store
the inflatable spare tire or jack and tools in
the passenger compartment .

Fuses and bulb s
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 bulb .
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 ho lders can have sharp
edges that can cause ser ious cuts, and parts
must be co rrectly taken apart 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 ­
sea led.
F or 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.
Ga s di sc ha rge la mp s (Xe non ligh ts):
Due to the high electrical voltage, have the bulbs
replaced by a qua lified techn ic ian . Head lights
with Xenon light can be identified by the high
voltage sticker.
LED headlights* requ ire no maintenance. P lease
contact your authorized Aud i dealer if a bulb
needs to be replaced.
A WARNING
Contact w it h high -vo ltage components of the
electrical system and improper rep lacement
of gas disc harge (Xenon) head light bu lbs 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 s hou ld change the bulbs
in gas disc harge 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 author ized Audi
dealer or other qual ified workshop . Ser ious
pe rsonal inju ry may resu lt from improperly
pe rformed wor k.
(D Tips
- If you must replace the light bulbs yourself,
always remember that the eng ine compart­
ment of any vehicle is a hazardo us a rea to
work in. Always read and heed all WARN­ INGS
~ page 272.
-It is best to ask you r author ized Audi dea le r
w henever you need to change a bulb.

" 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
operations.
Starting by pushing or
towing
~ Note
Vehicles 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 should 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 jumper cables to start the engine.
Jumper cables
Use only jumper cables of sufficiently large cross
section
to carry the starter current safely. Refer
to the manufacturer's specifications.
Use only jumper cables with
insulated terminal
clamps which are distinctly marked :
plus(+) cable in most cases colored red
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 avoid leaning
over the battery whenever possible.
-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 cables. 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 Audi dealer or author­ ized Audi Service Facility immediately to
have the vehicle battery checked.
- 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 substantial­
ly different "Ah " rating may cause an explo­
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. The battery case may have be weak­
ened.
- Use of batteries of different voltage or sub­
stantially different capacity (Ah) rating may
cause an explosion 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
c>page 272.
@ Note
- Applying a higher voltage booster battery
will cause 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.

-When connecting jumper cables, make sure
that they cannot get ca ught in any mov ing
parts in the engine compartment.
- Before you check anything in the engine
compartment, a lways read and heed a ll
