& WARNING
Incorrect tire pressures and/or underinflation can lead sudden tire
failure, los s of control, collision, serious personal injury or even
death.
• When the warning symbol appears in the instrument
cluster , stop and inspect the tires.
• Incorrect tire pressure and/or underinflation can cause
increased tire wear and can affect the handling of the vehicle and
stopping ability.
• Incorrect tire pressures and/or underinflation can also lead to
sudden tire failure, including a blowout and sudden deflation,
causing loss of vehicle control.
• The dr iver is responsible for the correct tire pressures for all
tires on the vehicle. The applicable pressure values are located on
a sticker on the driver 's side 8-pillar or on the inside of the fuel
filler flap .
& WARNING (co ntinued )
• Only when all tires on the vehicle are filled to the correct pres­
sure, the tire pressure monitoring* system can work correctly .
• The use of incorrect tire pressure values can lead to accidents or
other damage. Therefore it is essential that the driver observe the
specified tire pressure values for the tires and the correct pres­
sures for the function of the tire pressure monitoring system*.
• Always inflate tires to the recommended and correct tire pres­
sure before driving off .
• Driving with underinflated tires bend more , letting them get
too hot resulting in tread separation, sudden tire failure and loss
of control.
• Excessive speed and/overloading can cause heat build-up,
sudden tire failure and loss of control.
• If the tire pressure is too low or too high, the tires will wear
prematurely and the vehicle will not handle well.
• If the tire is not flat and you do not have to change a wheel
immediately, drive at reduced speed to the nearest service station
to check the tire pressure and add ai r as required.

& WARNING
Overloading a vehicle can cause loss of vehicle control, a crash or
other accident, serious personal injury, and even death .
• Carrying more weight than your vehicle was designed to carry
will prevent the vehicle from handling properly and increase the risk of the loss of vehicle control.
• The brakes on a vehicle that has been overloaded may not be
able to stop the vehicle within a safe distance.
• Tires on a vehicle that has been overloaded can fail suddenly,
including a blowout and sudden deflation, causing loss of control
and a crash.
• Always make sure that the total load being transported -
including the weight of a trailer hitch and the tongue weight of a
loaded trailer -does not make the vehicle heavier than the
vehicle's Gross Vehicle Weight Rating. •
Determining correct load limit
Use the example below to calculate the
total weight of the passengers and luggage
or other things that you plan to transport so
that you can make sure that your vehicle
will not be overloaded. .,_

tire failure and loss of vehicle control.
• All four wheels must be fitted with radial tires of the same
type, size (rolling circumference ) and the same tr ead pattern.
Driving with different t ires reduces vehicle handling and can lead
to a lo ss of control.
• If the spare ti re is not the same as the tires that are mounted
on the vehicle - for example with w inter tires - only use the spare
tire fo r a sho rt pe riod of t ime and drive with extra care. Refit the
normal road wheel as soon as safely possible.
• Never drive faster than the ma ximum speed for which the tires
on your vehicle are rated because tires that are driven faster than
their rated speed can fail suddenly .
• Overloading tire s cause heat build-up, sudden tire failure,
including a blowout and sudden deflation and loss of control.
• Temperature grades apply to tires that are properly inflated
and not over or underinflated.
• For technical reasons it is not always possible to use wheels
from other vehicles - in some c ases not even wheel s from the same
vehicle model.
• If you install wheel trim discs on the vehicle wheels , make sure
that the air flow to the brakes is not blocked. Reduced airflow to
the brakes can them to overheat , increasing stopping distance s
and causing a collision.
• Run flat tires may only be u sed on vehicles th at were equipped
with them at the factory. The vehicle must have a chassis designed
fo r run flat tires and a factor y-in stalled tire pres sure monitoring
system* that indicates a loss of tire pre ssure. Incorrect use of run
flat tires can lead to vehicle damage or accident s. Check with an
authorized Audi dealer or tire specialist to see if your vehicle can
be equipped with run flat tires . If run flat tires are used , they must
be installed on all four wheels. Mixing tire types is not permitted . ..,_

& WARNING
Improperly tightened or maintained wheel bolts can become
loose causing lo ss of control, a collision and serious per sonal
injury .
• Always keep the wheel bolts and the thread s in the wheel hub s
clean so the wheel bolts can turn easily and be properly tightened .
• Never grease or oil the wheel bolts and the threads in the wheel
hubs. They can become loose while d riving if greased or oiled , even
if tightened to the specified torque.
• Only use wheel bolts that belong to the rim being installed.
• Never use different wheels bolts on your vehicle.
• Always maintain the correct tightening torque for the wheel
bolts to reduce the risk of a wheel loss. If the tightening torque of
the wheel bolts is too low , they can loo sen and come out when the
vehicle is moving. If the tightening torque is too high, th e wheel

Low aspect ratio tires
Your Audi is fa cto ry -equ ip ped wi th low aspec t ratio tires. These tire s
have been thorough ly tested and been selected specifically for your
mode l for the ir supe rb perfo rmance, roa d fee l an d han dling un der a
var iety of driv ing cond it ions. Ask your author ized Audi dea ler for
more deta ils.
Th e low a spect rat io of these tires is indica ted by a nu meral of
55 or
less
in the tire's size designation. The numeral represents the ratio of
t he t ire's s idewall heigh t in relat io n t o its t re ad wi dth expressed in
percentage. Conventiona l tires have a height/width ratio of 60 or
more .
The performance of low -aspect -ratio tires is particularly sen sitive 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 mainta ined. Tire pres­
s ure s should be checked at lea st once a month and always before a
long trip =>
page 313, "Checking tire pressure".
What you can do to avoid tire and rim damage
Low aspect ratio ti res can be damaged more easi ly by impact w ith
potholes, curbs, gull ies or ridges on the road, p articular ly if the tire is
underinflated. .,_

App lies to veh icles: with Tire pressure monitoring syste m
Introduction
The tire pressure monitoring system monitors air pres­
sure in all four road wheels and the spare tire* while the
vehicle is moving.
As soon as the tire pressure monitoring system senses a significant
loss of air pressure in one or several tires, text messages and yellow
symbols appear in the instrument cluster display to alert the driver.
The
1warning light in the instrument cluster comes on when the tire
is significantly underinflated
=> page 17.
The warning light
L also illuminates in the case of a system malfunc­
tion.
The system continuously receives radio signals from sensors located
inside each tire.
Be aware that tire pressure is also dependent on the temperature of
the tire. For every 18 °F (10 °C) increase in tire temperature, tire pres­
sure increases by about 1.5 psi (0.1 bar). The tire warms up while the
vehicle is moving and tire pressure rises. So you should adjust tire
pressure only when the tires are
cold, when the temperature of the
tires is roughly the same as the ambient air temperature.
In order to keep the tire pressure monitoring system properly cali­
brated, tire pressure on all four tires and on the spare tire* should be
checked at regular intervals, adjusted if necessary and saved in the
proper setting (recommended pressure)=>
page 330.
The tire pressure is shown on the tire pressure label. On USA vehicles,
the tire pressure label is located on the driver's side B-pillar. On
Canada vehicles, the tire pressure label is located either on the
Safety first
driver's side B-pillar or inside the fuel filler flap. The tire pressure
label lists the recommended cold tire inflation pressures for the
vehicle at its maximum capacity weight and the tires that were on
your vehicle at the time it was manufactured. For recommended tire
pressures for normal load conditions, please see chapter
=> page 310.
The current temperatures and pressure of your tires can be viewed in
the MMI
=> page 329.
& WARNING
• When the tire pressure monitoring system warning light is lit,
one or more of your tires is significantly under-inflated. You
should stop and check your tires as soon as possible, and inflate
them to the proper pressure as indicated on the vehicle's tire pres­ sure label =>
page 310. Driving on a significantly under-inflated
tire causes the tire to overheat and can lead to tire failure. Under­
inflation also is likely to impair the vehicle's handling and stop­
ping ability.
• Do not adjust tire pressure when tire temperature is excessive.
This could lead to serious tire damage and even cause the tire to
burst, with the additional danger of an accident.
<£> For the sake of the environment
Driving with under-inflated tires reduces fuel efficiency and tire tread
life.
(I) Tips
• Each tire, including the spare*, should be checked monthly when
cold and set to the recommended inflation pressure as specified on
the tire pressure label=>
page 310.
• The tire pressure monitoring system helps the driver to keep an
eye on tire pressures. But the driver still has the responsibility for
maintaining the correct tire pressure. .,,,
