If you wish to improve comfort
when operating the vehicle at
normal load (up to 2 occu­
pants), you can adjust tire
pressures to those specified
for normal vehicle load. Before
operating the vehicle at maxi­ mum load, you must increase
the tire pressures to those
specified for maximum vehicle
load
c> .&. .
Bear in mind that the tire pres­
sure monitoring system can on­
ly monitor the tire pressures
you have stored. The system does not recognize the load
condition of your vehicle.
The effectiveness of the tire p ressure monitoring system
will be impaired if you store normal load pressures but then
operate the vehicle at its maxi­
mum load

236 Tires and wheels
Because technical changes may
be made to vehicle equipment
during the model year, always
compare the tire size designa­
tion on the tire pressure label
on your vehicle with the tires on
your vehicle . Make sure that the
tire size information on the ve­ hicle label is the same as the
size of the tires on the vehicle .
This is especially important if
the vehicle belongs to someone else or you bought the vehicle
with different rims/tires or you bought the vehicle as a previ ­
ously owned vehicle.
Remember, your safety and
that of your passengers also de­ pends on making sure that load
limits are not exceeded . Vehicle
load includes everybody and ev­
erything in and on the vehicle .
These load limits are technical­ ly referred to as the vehicle's
Gross Vehicle Weight Rating
("GVWR"). The Gross Axle
Weight Rating ("GAWR") is the
maximum load that can be ap­
plied at each of the vehicle's
two axles . The Gross Vehicle
Weight Rating and the Gross
Axle Weight Rating are listed on the safety compliance stick- er label located on the driver's
side B-pillar. The tire pressure
label on your Audi lists the
maximum combined weight of
all of the occupants and lug­
gage or other cargo that the ve­
hicle can carry. For the location
of the tire pressure label

&_ WARNING
-
Overloading a vehicle can
cause loss of vehicle control,
a crash or other accident, se­
rious personal injury, and
even death .
- Carrying more weight than
your vehicle was designed to carry will prevent the ve­
hicle from handling properly
and increase the risk of a
loss of vehicle control.
-The brakes on a vehicle that has been overloaded may
not be able to stop the vehi­
cle 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
does not make the vehicle .,.

240 Tires and wheels
the driver observe the speci­
fied tire pressure values for
the tires and the correct pressures for the function of
the tire pressure monitoring
system.
-Always inflate tires to the
recommended and correct
tire pressure before driving
off.
-Driving with underinflated tires bend more, letting
them get too hot resulting
in tread separation, sudden
tire failure and loss of con­
trol.
-Excessive speed and/over­
loading 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 near­
est service station to check
the tire pressure and add air
as required.
(D Note
Driving without valve stem
caps can cause damage to
the tire valves. To prevent
this, always make sure that
factory installed valve stem
caps on all wheels are secure­ly mounted on the valve.
@ For the sake of the environment
Underinflated tires will also
increase the fuel consump­
tion.
Tires and vehicle load limits
There are limits to the amount
of load or weight that any vehi­
cle and any tire can carry. Ave­ hicle that is overloaded will not
handle well and is more diffi­
cult to stop. Overloading can
not only lead to loss of vehicle
control, but can also damage
important parts of the vehicle
and can lead to sudden tire fail­
ure, including a blowout and
sudden deflation that can cause
the vehicle to crash.
Your safety and that of your passengers also depends on
making sure that load limits are~

256 Tire s and wheel s
Description
The tire pressure monitoring system monitors
th e pressure in the four tir es when driving .
The system uses sensors that measure the
temperature and pressure in the tires. Theda­
ta is sent from these sensors to the control
module by rad io frequency .
The tire pressure monitoring system shows
the current pressures and temperatures
of the
tires in the Infotainment system
c:> page 256 .
It also compares the current tire pressures
with the sto red press ures and gives a warn ing
in the dr iver information system if the t ire
p ressu re is different from what is sto red
<=:> page 257.
The system does not detect if the sto red ti re
p ressu res matc h the recommended tire pres­
sures . Yo u must resave the tire p ress ures
<=:> page 257:
- every time the tire pressures change, for ex­
amp le when the load in the veh icle changes,
- after replac ing a tire, or
- i f wheels with new wheel sensors are used .
.,&. WARNING
- The tire pressure mo nitor ing system as­
sists t he d rive r in monito ring t ire pres­
s ur es. The dr iver is responsible fo r having
the tires in flated t o the co rrec t press ure.
- Do not change t he tire pressu re when the
t empe rat ure of the ti re is high. This
cou ld resul t in ser io us damage to the ti re
and even cause t he tire to burst, increas ­
ing th e risk of an accident.
- A tire with low pressure flexes more . This
heats the tire up too much. This could
cause the tread to separate and even
cause the tire to burst, increasing the
risk
of a n accident.
- The tire pressure mon itor ing system
does not warn about damage or defects
in the tire construct ion that could ca use
the tire to b urst, for examp le . Inspect
yo ur t ires regularly .
{® For the sake of the environment
Low tire pressure increases fuel consump­
tion and tire wear .
(D Tips
- If tires are replaced, the senso rs/valves
do not need to be removed o r replaced.
Just replace the va lve stem and, if neces­
sary, the valve and the whee l electronics .
If you have questions, see your a uthor­
ized Aud i dea ler o r a qualified workshop .
- Us ing the tire mob ility kit can results in
an incorrect display or a ma lfunction in
t he tire pressure monito ring system .
Have the sensors replaced by an a uthor­
ized Aud i dea le r o r a qua lified workshop.

A WARNING
You or your passengers could be injured
while changing a wheel if you do not fol­
low these safety precautions:
- If you have a flat tire, move a safe dis­
tance off the road. Turn off the engine,
turn the emergency flashers on and use
other warning devices to alert other mo­
torists.
- 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
front wheel is lifted off the ground, plac­ ing the Automatic Transmission in P
(Park) will
not prevent the vehicle from
moving.
What do I do now? 263
- Before you change a wheel, be sure the
ground is level and firm. If necessary,
use a sturdy board under the jack.
- Always store the vehicle tool kit, the jack
and the replaced tire in the luggage com­
partment
