dealer or qualified workshop. •
Low aspect ratio tires
Your Audi is factory-equipped with low aspect ratio tires . These tires
have been thoroughly tested and been selected specifically for your
model for their superb performance, road feel and hand ling under
a variety of driving conditions . Ask your authorized Audi dealer for
more details.
The low aspect ratio of these tires is indicated by a numeral of
55 or
less
in the tire's size designation. The numeral represents the ratio
of the tire's sidewa ll height in relat ion to its tread width expressed
in percentage. Conventional tires have a height/width ratio of 60 or
more.
The performan ce of low -aspect-ratio tires is particularly sensitive to
improper inflation pressure. It is therefore important that low
aspect ratio tires are inflated to the specified pressure and that the
inflation pressure is regularly checked and maintained. T ire pres­
s ures should be checked at least once a month and always before a
long trip => page 379,
"Checking tire pressure".
What you can do to avoid tire and rim damage
Low aspect ratio tires can be damaged more easily by impact with
potho les, curbs, gullies or ridges on the road, particularly if the tire
is underinflated.
In order to minimize the occurrence of impact damage to the tires
of your vehicle, we recommend that you observe the following precautions:
• Always ma inta in recommended inflation pressures. Check your
tire pressure every 2,000 miles (3,000 km) and add air if necessary.
• Drive carefully on roads with potholes, deep gu llies or ridges.
The impact from driving through or over such obstacles can
damage your tires. Impact with a curb may also cause damage to
your tires . •
After any impact, immediately inspect your tires or have them
inspected by the nearest authorized Audi dealer. Replace a
damaged tire as soon as possible.
• Inspect your tires every 2,000 miles (3,000 km) for damage and
wear. Damage is not always easy to see. Damage can lead to loss of
air and underinflation, which could eventually cause tire failure. If
you believe that a tire may have been damaged, replace the tire as
soon as possib le.
• T hese tires may wear more quickly than others .
• Please also remember that, whi le these tires deliver respons ive
handling, they may ride less comfortably and make more noise than
other choices .
Reduced performance in winter /cold season
conditions
A ll tires are designed for certain purposes. The low aspect ratio,
u ltr a high performance tires originally installed on your vehic le are
intended for maximum dry and wet road performance and handling.
They are not suitable for cold, snowy or icy weather conditions. If
you drive under those circumstances, you should equip your vehic le
with all -season or winter tires , wh ich offer better traction under
those conditions. We suggest you use the recommended snow or all -season tires specified for your vehicle, or their equivalent .
Refer to=>
page 329for more detailed information regarding winter
tires. •

& WARNING (continued)
front wheel is lifted off the ground, placing the Automatic Trans­
mission in "P" {Park) will
not prevent the vehicle from moving.
• Before you change a wheel, be sure the ground is level and firm.
If necessary, use a sturdy board under the jack.
• After installing the spare wheel, make sure that you replace the
flat tire/wheel in its storage area properly and tighten the knurled
retaining screw securely. •
Changing a wheel
When you change a wheel, follow the sequence described
below step-by-step and in exactly that order.
1. Activate the vehicle jack mode (only vehicles with Adap ­
tive Air Suspension)~
page 184.
2. Remove the decorative wheel cover*. For more details
see also ~
page 340, "Decorative wheel covers" or
~ page 340, "Wheels with wheel bolt caps".
3. Loosen the
wheel bolts~ page 341.
4. Locate the proper mounting point for the jack and align
the jack below that point~
page 341.
5. Lift the car with the jack ~ page 341.
6. Remove the wheel with the flat tire and then install the
spare
~ page 343.
7. Tighten all wheel bolts lightly.
8.
Lower the vehicle with the jack.
9. Use the wheel bolt wrench and
firmly tighten all wheel
bolts~
page 341 .
10. Replace the decorative wheel cover*.
11. Deactivate the vehicle jack mode (only vehicles with
Adaptive Air Suspension)~
page 184.
& WARNING
Always read and follow all WARNINGS and information => & in
uRaising the vehicle" on
page 341 and=> page 344. •
After changing a wheel
A wheel change is not complete without the doing the
following.
- Store and secure the wheel you replaced in the spare
wheel well.
- Replace the tools and the jack in their proper location.
- Check the tire pressure on the spare wheel immediately
after mounting it.
- As soon as possible, have the
tightening torques on all
wheel bolts checked with a torque wrench. The correct
tightening torque is 90 ft lb (120 Nm).
- Have the flat tire
replaced as soon as possible.
[ i] Tips
• If you notice that the wheel bolts are corroded and difficult to
turn while changing a tire, they should be replaced before you check
the tightening torque.
• Drive at reduced speed until you have the tightening torques
checked .•

standards. Therefore, vehicles built for the U.S .A. and Canada differ
from vehicles sold in other countries.
If you plan to take your vehicle outside the continental limits of the
United States or Canada, there is the possibility that
• unleaded fuels for vehicles with catalytic converter may not be
available;
• fuel may have a considerably lower octane rating. Improper fuel
may cause engine damage;
• service may be inadequate due to lack of proper service facilities,
tools or testing equipment;
• replacement parts may not be readily available .
• Navigation systems for vehicles built for the U.S.A. and Canada
will not necessarily work in Europe , and may not work in other coun­
tries outside of North America.

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 require­
ments to a minimum. However, a certain amount of regular mainte­
nance is still necessary to assure your vehicle 's safety, economy and
reliability. For detailed vehicle maintenance consult your Mainte­
nance & Warranty booklet .
Under difficult operating conditions, for example at extremely low
outside temperatures, in 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 emis ­
sion standards are maintained, thus minimizing adverse effects on
the environment. •
Important considerations for you and your
vehicle
The increasing use of electronics, sophisticated fuel injection and
emission control systems, and the generally increasing technical
complexity of today's automobiles, have steadily reduced the scope
of maintenance and repairs which can be carried out by vehicle
owners. Also, safety and environmental concerns place very strict
limits on the nature of repairs and adjustments to engine and trans­
mission parts which an owner can perform.
Maintenance, adjustments and repairs usually require special tools,
testing devices and other equipment available to specially trained .,_
