your vehicle with correctly fitted winter tires or a ll- season tires,
w hen winter ro ad condit ions are e xpected. T his also i mproves the
vehic le 's brak ing performance and reduces stopp ing distances.
Summer tires provide less grip on ice and snow .
Winter tires (s now ti res) mus t always be fitted on a ll four whe els .
Compatible tire pressure monitoring sensors must be installed on
all f our winte r tires fo r th e tir e pres su re m onitori ng sy stem to f unc ­

Ask your authorize d Audi dealer or qualified worksho p for permitted
winter tire sizes. Use on ly rad ial winter t ires .
Winter tires lose their effectiveness when the tread is worn down to a depth of 0 .157 inc h (4 m m).

& WARNING
Winter tires have maximum speed limits that may be lower than
your vehicle's maximum speed . Always know the maximum speed
before driving off . Never dr ive faster than the speed permitted for
your specific winter tires. This will cause damage to the tires
leading to an accident and serious personal injury to you and your
passengers .
& WARNING
Driving faster than the maximum speed for whi ch the winter tires
on your vehicle were designed can cause tire failure including a
blowout and sudden deflation , loss of control , crashes and serious
personal injuries. Have worn or damaged tires replaced immedi­
ately.
• Winter tires have maximum speed rating that may be lower
than your vehicle's maximum speed .
• Never drive faster than the speed for which the winter or other
tires installed on your vehicle are rated.
& WARNING
Always adjust your driving to the road and traffic conditions .
Never let the good acceleration of the winter tires and all -wheel
dr ive tempt you into taking extra risks . Always remember :
• When braking , an all -wheel drive vehicle handle s in the same
way as a front drive vehicle .
• Drive carefully and reduce your speed on icy and slippery roads,
even winter tires cannot help under black ice conditions .
~ For the sake of the environment
Use summer tires when weather conditions permit . They are
q uieter, d o not wear as qu ick ly and re duce fue l c on sumption .•
Snow chains
S now c hains may be fitted on ly to t he rear w hee ls, and only to
certain tire sizes. Ask your autho rized A udi dea ler on which tire
s izes sn ow cha ins ca n be used .
T he snow chains must hav e low -prof ile links and must not be thicker
th an 0 .53 in ch (13 .5 mm), inc lu d in g the loc k. .,_

0 Note
The specified torque for the wheel bolts is 120 ft lb (160 Nm) with a
tolerance of± 7,4 ft lb(± 10 Nm). Torque wheel bolts diagonally.
After changing a wheel, the torque must be checked as soon as
possible with a torque wrench -preferably by an authorized Audi
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 handling 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 sidewall height in relation to its tread width expressed
in percentage. Conventional tires have a height/width ratio of 60 or
more.
The performance 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. Tire pres­
sures should be checked at least once a month and always before a
long trip~
page 353, "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
potholes, 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 maintain 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 gullies 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 possible.
• Th ese tires may wear more quickly than others.
• Please also remember that. while these tires deliver responsive
handling, they may ride less comfortably and make more noise than
other choices.
Reduced performance in winter/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 winter 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 363for more detailed information regarding winter
tires. •

& WARNING (continued)
• 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.
- Always store all jacking equipment, tools, and the inflatable
spare tire in the luggage compartment.
- Tighten the knurled retaining screw for the inflatable spare
tire securely.
0 Note
• Th e inflatable spare tire has been developed specifically for this
vehicle model. It must not be exchanged or used for other vehicle
models. Similarly, inflatable tires from other vehicle models must
not be used.
• Normal summer or winter tires must not be installed on the
inflatable tire rim.•
Changing a wheel
Before changing a wheel
Observe the following precautions for your own and your
passenger's safety when changing 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)=> &.
- Engage the
parking brake to prevent your vehicle from
rolling unintentionally=> &. -
Move
selector lever to position P =:> & .
- If you are towing a trailer: unhitch the trailer from your
vehicle.
- Block the diagonally opposite wheel with the folding
chocks or other objects.
- Take the
jack and the inflatable spare tire out of the
luggage compartment=>
page 370.
& 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 flashers 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 road 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 with the
folding chocks or other objects. When one front wheel is lifted off
the ground, placing the Automatic Transmission 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 inflatable spare tire, make sure that you
replace the flat tire/wheel in its storage area properly and tighten
the knurled retaining screw securely. •
