The cor rect tire pressure for the spare wheel is located on a label
either on the driver 's side B -pillar o r inside the fue l fil ler flap .
Because technica l changes may be mad e to vehicle equipmen t
du ring the mo del year, always co mpare the tire si ze designa tion on
the tire pressure label on your vehicle with the tires on your vehicle .
Make sure t hat the t ire size info rmati on on t he veh icle labe l is the
same as the size of the tires on the vehicle . This is especially impor ­
tan t if the vehicle bel ongs t o some one e lse or you boug ht the
vehic le with different rims/tires or you bought the vehicle as a previ ­
ously owned ve hicle.
Reme mbe r, you r safety an d that of your passengers a ls o depe nds
on making sure tha t load limi ts are not exceed ed. Vehicle load
inc ludes everybody and everyt hin g in an d on th e vehicle . T h ese load
limits are technical ly referred to as the vehicle's Gross Vehicle
Weigh t Ra ting ("GVWR"). The Gro ss Axle Weigh t Ra tin g ("GAWR") is
the maximum load that can be applied at each of the vehicle's two axles
. The G ross Vehic le We ight Rating and the Gross Axle Weight
Rat ing are lis ted on the safety compliance sticker labe l located
either on the driver 's side 8 -pillar or on the inside of the fue l fi ller
fl ap . The ti re p ressure label on you r Aud i lists the maximum
combined weight of a ll of the occupants and luggage or other cargo
th at th e vehic le can carry . Fo r the location o f the t ire pressure labe l

& WARNING
Overload ing 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 des igned to carry
will prevent the vehicle from handling properly and increase the
risk of a loss of vehicle control . .,_

•
& WARNING (continued)
• 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
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.
& WARNING
• Incorrect tire pressures and/or underinflation can lead to a
serious or fatal accident.
• Incorrect tire pressures and/or underinflation cause increased
tire wear and can affect the handling of the vehicle.
• Incorrect tire pressures and/or underinflation can also lead to
sudden tire failure, including a blowout and sudden deflation,
causing loss of vehicle control. •
Checking tire pressure
The correct tire pressure for the tires originally installed
on your vehicle is listed on the tire pressure label located
either on driver's side 8-pillar or inside the fuel filler flap.
The recommended tire pressures are on the tire pressure label and
in the table~
page 330, "Cold tire inflation pressure".This means
that the pressure must be checked and adjusted when the tire has
not been driven for more than a couple of miles (kilometers) at low
speeds during the previous three hours. Air in the tires expands
when the tire heats up as a result of internal friction as it flexes in
use. The tire pressure is higher when the tire has warmed up than
when it is "cold ." It
is the inflation pressure in a "cold" tire that counts. Therefore, you
should never let air out of a warm tire to match "Cold tire inflation
pressure" recommendations~
page 330. The tires would then be
underinflated and could fail suddenly.
The tire pressure label on your Audi lists the recommended cold tire
inflation pressures at maximum capacity for the new, original equip ­
ment tires that were on your vehicle at the time it was manufac­
tured. For the location of the label
~ page 330, fig. 274.
Most tires lose air naturally over time. They can also lose some air if
you drive over a pothole or hit a curb while parking. It is usually not possible to see whether the radial tires used today are underinflated
just by looking at them.
Therefore, be sure to check tire pressures at least once a month and
always before going on a long trip. Make sure to take the number of
people and the amount of luggage into account when adjusting tire
pressure for a trip -even one that you would not consider to be
"long ." See~
page 335, "Tires and vehicle load limits" for more
important information.
Always use an accurate tire pressure gauge when checking and
adjusting inflation pressures . Check all of the tires and be sure not
to forget the spare tire . If the pressure in any tire is too high when
the tire is "cold," let air out of the tire slowly with the edge of the tire
gauge and keep checking the pressure until you reach the pressure
that is correct for the load (passengers and luggage) and kind of
driving you plan to do.
If the pressure in any tire is too low, note the difference between the
pressure in the cold tire and the pressure you need and add the air
that you need to reach the correct pressure for the vehicle load
(passengers and luggage) for the tires on your vehicle as listed on
the on your vehicle and in this manual and the kind of driving you
plan to do.
Never exceed the maximum inflation pressure listed on the tire
sidewall for any reason.
Remember that the vehicle manufacturer, not the tire manufacturer,
determines the correct tire pressure for the tires on your vehicle. .,,_

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

& 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. When one ..,
