being loaded on the vehicle.
That weight may not safely
exceed the available cargo
and luggage load capacity
calculated in Step 4.
6. If your vehicle will be towing
a trailer, load from your trail­
er will be transferred to your
vehicle. Consult this manual
to determine how this re­
duces the available cargo
and luggage load capacity of
your vehicle.

(¢ page 257, fig. 199) to de­
termine the designated load rating for a specific tire.
Tire service life
The service life of tires depends
on a lot of different things in­
cluding proper installation and
balancing, correct tire pressure and driving style.

cators (TWI)

wear
Tread Wear Indicator (TWI)
The original tires on your vehi­
cle have
1/16 inch (1.6 mm)
high "wear indicators"
¢ fig. 197 running across the
tread. Depending on the make,
there will be six to eight of
them evenly placed around the
tire. Marks on the tire sidewall (for example "TWI" or other
symbols) indicate the positions
of the tread wear indicators.
Worn tires must be replaced.
Different figures may apply in
other countries
¢ & .
Tire pressure
Incorrect tire pressure causes
premature wear and can cause
sudden tire blow-out. For this
reason, tire pressure must be
checked at least once a month
¢ page 249.

272 What do I do no w?
• Always store the vehicle too l kit, the jack*
and the replaced tire in the luggage com­
partment
¢ page 132.
• Unhook the cargo floor before clos ing the
rear lid.
Using th e spare tir e (compac t spare tir e)
The compact spare tire is on ly intended for
emergencies until yo u can reach a repair shop.
Replace it as quickly as possible with a stand­
ard wheel and tire.
There are some restrictions on the use of the compact spare tire. The compact spare tire has been des igned specifically for your type of
vehicle. It must not be swapped with a com­ pact spare tire from another type of vehicle.
Sn ow chain s
For technical reasons, the use of snow chains
on the compact spare tire is
not permitt ed .
If you do have to dr ive with snow cha ins and a
front tire fails, mount the spare wheel with
tire instead of a rear tire . Install the snow
chains on the rear tire and use it to replace
the defective front tire.
A WARNING
- Never use the spare tire if it is damaged
or if it is worn down to the tread wear in­
dicators .
- If the spare tire is more than 6 years o ld,
use it only in an emergency and with ex­
t reme caution and careful driving .
- The spare tire is intended only for tem­
porary and short-term use. It should be
replaced as soon as possible w ith the
normal wheel and t ire.
- After mounting the compact spare tire,
the tire pressure must be checked as
soon as poss ible. The tire pressure of the
c ompact spare tire must be 4.2 bar; oth­
erwise, you risk hav ing an accident .
- Do not drive faster than 50 mph (80 km/
h). You risk having an acc iden t.
- Avoid full-throttle acce le rat ion, heavy
braking, and fast corner ing . You risk hav­
ing an a cc ident. -
Never drive using more than one spare
wheel and tire. You r isk having an acci­
dent.
- Normal summer or winter tires must not
be mounted on the compact spare wheel
rim.
- 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 ax le in the event of a flat in a rear
tire. The new ly available front wheel
m ust then be installed in place of the
rear whee l w ith the flat tire. Installing
the tire chain before mounting the whee l
and tire is recommended.
- Loose items in the passenger compart ­
ment 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 compart­ ment.
Changing a wheel
Before changing a wheel

move to a safe location ( for instance, behind
the guardrail) ¢,& .
• Engage the
par king brake to prevent your
vehicle from rolling unintentionally c> _& .
• Move

gency crews and working personnel who have the necessary tools and equipment to
perform these operations.
Starting by pushing or
towing
(D Note
Ve hicles w ith an au tomatic tra nsmission
cannot be started by pus hing o r tow ing.
Starting with jumper
cables
If necessary, the engine can be started by
connecting it to the battery of another vehi­
cle.
If the engine shou ld fail to start because of a
discha rged o r wea k battery, the battery can be
connected to the battery o f
another vehicle,
using a
pair of jumper cables to start the en­
g ine.
Jumper cables
Use only jumper cables of sufficiently la rge
c ross section to carry the starter c urrent safe­
l y. Refer to the man ufacturer's specifications.
Use only jumper cables with
insulated te rm i­
na l clamps wh ic h are d istinctly marked:
plus(+) cable i n mos t cases co lore d red

Operating your vehicle
outside the U.S.A. or
Canada
Government regu lations in the United States
and Canada require that automobiles meet
specific emission regulations and safety
standards. Therefore, veh icles built for the
U.S.A . and Canada differ from vehicles sold in
other countries .
If you p lan to take your vehicle outside the
continental limits of the United States or Can­
ada, there is the possibility that:
- unleaded fuels for vehicles with cata lytic
converter may not be available;
- fuel may have a considerably lowe r octane
rating. Improper fuel may cause engine
damage ;
- service may be inadequate due to lack of
proper service facilities, tools or testing
equipment ;
- replacement pa rts may not be readily availa­
ble.
- Navigation systems for vehicles built for the
U.S.A. and Canada will not necessar ily work
in Europe, and may not work in other coun­
tries outside North America .
(D Note
Audi cannot be responsible for mechanical
damage that could result from inadequate
fuel, service or parts availability.

Maintenance
General
Your vehicle has been designed to help keep
maintenance requirements to a minimum.
However, a certain amount of regular mainte­
nance is still necessary to assure your vehicle's
s afety, economy and rel iability. For detailed
vehicle maintenance consult your Warranty &
Maintenance booklet.
Under difficult operating conditions, for ex­
ample at extremely low outside temperatures,
i n very dusty regions , when towing a trailer
very frequently, etc., some service work
should be performed between the intervals
specified. This applies particularly to:
- oil changes, and
- cleaning or replacing the air filter .
(® For the sake of the environment
By regularly maintaining your vehicle, you
help make sure that emission standards
are maintained, thus minimizing adverse
effects on the environment.
Important considerations for you and
your vehicle

ed fuel injection and emission contro l sys-
tems, and the genera lly increasing technical
