than your vehi cle' s maximum speed.
• Never drive faster than the speed for which the winter or other
tire s installed on your vehicle are rated.
& WARNING
Always adjust your driving to the road and traffi c cond it ions .
Never let the good acceleration of the winter tires and all -wheel
drive tempt you into taking e xtr a risks . Alway s remember :
• When braking, an all -wheel drive vehicle handles in the same
way as a front drive vehi cle.
• Drive carefully and reduce your speed on icy and slippery road s,
even winter tires cannot help under black ice condit ions .
<£> For the sake of the environment
Use summer tires when weather conditions permit. They are
qu ieter, d o not wear as qu ick ly and reduce fue l con sump tion.•
Snow chains
Snow chains may be fitted only to t he fr ont w heels, and only to
certain tire sizes . Ask your authorized Aud i dealer on which tire
s izes sn ow chains ca n be used .
I f you are going to use snow chains, then you must instal l them on
the front wheels at least.
Th e snow chains must have low- prof ile l inks and must n ot be t hicke r
than 0 .53 inch (13 .5 mm), including the lock. Remove whee
l center covers and trim discs before putting snow
chains o n yo ur vehicle =>
(D. For safe ty reaso ns cover caps must
then be fitted over the wheel bolts. These are available from autho ­
r iz ed Audi dealer s.
& WARNING
Using the wrong snow chain s for your vehicle o r installing them
incorre ctly can increase the risk of loss of control leading to
s erious personal injury .
• Snow chains are available in d iffe rent sizes . Always make sure
to follow the instructions provided by the snow chain manufac ­
turer .
• When driving with snow chains never drive faster than the
speed permitted for your specific snow chains .
• Always observe local regulations.
(}) Note
• Remove snow c hai ns be fore d riving on roads not covered wit h
snow to avoid damaging tires and wearing the snow cha ins down
unnec essarily .
• Snow chains, which come into direct contact with the wheel rim,
can scratc h or damage it. Therefore, make sure tha t the snow cha ins
are suitably covered. Check the position of the snow chains after
dr iv in g a few yards an d cor rect if necessary . Fo llow the i nstruct ions
from the snow cha in manufacturer when do ing so.

•
• 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 eventua lly cause tire failure. If
you believe that a tire may have been damaged, replace the tire as soon as possible .
• These tires may wear more quickly than others .
• Please a lso remember that, while these tires deliver responsive
handling, they may ride less comfortably and make more noise than
other choices.
Reduced performance in vvinter /cold season
conditions
All tires are designed for certain purposes. The low aspect ratio,
ultra high performance tires originally installed on your vehicle 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 vehicle
with all -season or win ter tires, which 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 284for more detailed information regarding winter
tires. •

==> page 291, fig. 215. Turn it counter-clockwise.
- Take out the spare wheel.
- Disengage and lower the floor panel before you close the
luggage compartment lid again.
Storing the replaced wheel
-Place the replaced wheel inside the spare wheel well in
the luggage compartment.
- Tighten the knurled retaining screw clockwise to secure
the wheel in place.
- Disengage and lower the floor panel before you close the
luggage compartment lid again.
& WARNING
Loose items in the passenger compartment can cause serious
personal injury during hard braking or in an accident .
• Never store the spare wheel or jack and tools in the passenger
compartment.
• Always store all jacking equipment, tools, and the spare wheel
in the luggage compartment.
• Tighten the knurled retaining screw for the spare wheel
securely.
[ i] Tips

Applies to vehic les: w ith a space -saving spare wheel
Space-saving spare wheel
The compact spare wheel is only intended to be used for
a short time.
Using the space-saving spare wheel
The space -saving spare wheel is only intended for emergencies
until you can reach a repair shop. Replace it as quickly as possible
with a normal wheel.
There are some restrictions on the use of the space -saving spare
wheel
=> ,&. . The space-saving spare wheel has been developed
especially for your type of vehicle. It must not be exchanged for the
space-saving spare wheel from another type of vehicle.
Normal summer or winter tires must not be fitted on the space ­
saving spare wheel rim.
Snow chains
For technical reasons, the use of snow chains on the space-saving
spare wheel
not permitted .
If you do have to drive with snow chains and have a tire failure on a
front wheel, install the space-saving spare wheel in place of a rear
wheel. Install the snow chains on the rear wheel and use it to
replace the defective front wheel.
& WARNING
• After installing the space-saving spare wheel, the tire pressure
must be checked as soon as possible. The tire pressure must be
adapted to the load condition of the vehicle according to the tire .,_

pressure table - risk of accident! Use the highest tire pressure in
the table.
• Do not drive faster than 50 mph (80 km/h) - risk of accident!
• Avoid full-throttle acceleration, sharp braking, and fast
cornering - risk of accident!
• Never drive using more than one space-saving spare wheel -
risk of accident!
• Normal summer or winter tires must not be fitted on the space­
saving spare wheel rim. •
Wheel change
Before changing a wheel
Follow these points for your own and your passenger's
safety when replacing a wheel.
-After you experience a tire failure, pull the car well away
from moving traffic and try to reach level ground before
you stop => & .
- All passengers should leave the car and move to a safe
location (for instance, behind the guardrail)=>& .
- Apply the parking brake firmly=>&.
- Move selector lever to position Pon an automatic trans-
mission; put manual transmission in first gear =>& .
- If you are towing a trailer: unhitch the trailer from your
vehicle.
- Take the tool case and the spare tire=>
page 290 out of
the luggage compartment.
& WARNING
You or your passengers could be injured while changing a wheel if
you do not follow these safety precautions:
• If you have a flat tire, move a safe distance off the road. Turn off
the engine, turn the emergency flasher on and use other warning devices to alert other motorists .
• Make sure that passengers wait in a safe place away from the
vehicle and well away from the roadway and traffic.
• To help prevent the vehicle from moving suddenly and possibly
slipping off the jack, always fully set the parking brake and block
the wheel diagonally opposite the wheel being changed. When one
front wheel is lifted off the ground, placing the Automatic Trans­
mission in "P" (Park), or engaging a gear in a manual transmission
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 remount
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 exactly in that order.
1. Remove the decorative wheel cover*. For more details
see also =>
page 294, "Decorative wheel covers" or
=>
page 295, "Wheels with cap-covered wheel bolts".
2. Loosen the wheel bolts=>
page 295.
3. Locate the proper mounting point for the jack and align
the jack below that point=>
page 296.
4. Lift the car with the jack=> page 296. _,..
