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

Note that the tire pressure also depends on
the tempe rature of the tire . Every 50 °F
(10 °C) increase in tire temperature results in
the tire pressure increasing by approximately
0 .1 bar. The tire pressure increases as the en­
g ine becomes warmer while drivi ng .

Malfunctions
Fig. 202 Display: indicator light wit h a message
If the tire pressure monitoring system is not
available, the
Ill ind icator light appears in
the dr iver information system. The
RIJ ind ica­
tor light also blinks for approximate ly one mi­
nutes each time the ignit ion is switched on.
The tire pressure monitoring system cannot be selected in the Infotainment system. The
malfunction could be caused by the following
examples:
- If the message appears at the end of the
adaptation phase, the system cannot detect
the wheels installed on the vehicle. This may
result from one or more wheels being instal­
led without wheel sensors or with incompat­
ible wheel sensors .
- A wheel sensor or another component has
failed .
- Using snow chains can affect the function of
the system because of the shielding effect
of the chains.
- The tire pressure monitoring system is not
available due to a malfunction.
- Transmitters with the same frequency, such
as headphones or remote-controlled devi ­
ces, may cause a temporary system mal­
function due to the strong electromagnetic
field .
The
Ill indicator light turns off once the tire
pressure monitoring system is available again.
I f you cannot correct the malfunction and the
Ill indicator light stays on, drive to an author­
ized Audi dealer or a qualified workshop to
have the malfunct ion corrected.

t ric pump directly onto the va lve.
• Insert the plug@~
fig. 206 into the socket
for the cigarette lighter.
• Switch on the ignition.
• Move the switch @~
fig. 207 on the e lec­
tric air pump
ll to position I. After 5 mi­
nutes, tire pressure must have reached at
least 1.8 bar.
• Switch the electric air pump off -switch in
pos it ion
0 . If the requ ired tire pressure of at
least 1.8 bar has not been reached, it is not
poss ible to make a repa ir with the tire seal­
ant. Seek professional assistance.
Disassembling Tire Mobility System
• Remove the hose from the valve and pull the
plug out of the socket.
• Screw the dust cap onto the valve .
• Place the empty sealant bottle back in the
original packaging and clip it in place under
the floor so that no tire sealant can run out
into the vehicle.
• Place the electric air pump in the luggage
compartment for the time being.
1l The electr ic air p ump sho uld never ru n fo r long er than
6 minut es.
• Start driving right away so that the sealant
is distributed in the tire .
A WARNING
=
- Follow the manufacturer 's safety instruc-
tions on the decal for the air pump and
the sealant bottle.
- If a tire pressure of 1.8 bar cannot be
achieved after pumping for 5 minutes,
the t ire is too severely damaged. Do not
continue to dr ive .
- Seek professional ass istance if it is not
possible to repa ir the tire w ith the tir e
sealant.
(D Tips
- Do not operate the electric air pump for
more than 6 minutes without stopping,
otherwise it can overheat . When the air
pump has cooled down, you can continue
to use it.
- If sealant has escaped, allow it to dry,
then you can pee l it off.
Final check
After driving for a short distance, tire pressure must be checked
• After driving for about 10 min utes, stop and
check the tire pressure.
• If tire pressure is sti ll at least 1.3 bar, in­
flate the tire to specif ied pressure (see driv­
er's side B-pillar), drive to the next repair
shop and have the tire and the sealant bot­
tle replaced .
• If tire pressure is less than 1.3 bar, the tire
is too severely damaged . Do not continue to
drive. Seek professional assistance.
A WARNING
If tire pressure is less than 1.3 bar after
driving for 10 minutes, the tire is too se­
verely damaged. Do not continue to drive.

functionality to the Tire Mobility System.
Changing a wheel
Before changing a wheel
Observe the following precautions for your
own and your passenger's safety when chang­
ing 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 c:> &, .
.. All passengers should leave the car and
move to a safe location (for instance, behind
the guardrail)
c:> &, .
.. Engage th e parking brake to prevent your
vehicle from rolling unintentionally
c:> &, .
.. Move selector lever to position Pc:> &, .
.. Take the jack out of the luggage compart­
ment
c> page 259.
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

If you are changing the wheel on a steep
incline, use a rock or similar object to
block the opposite wheel to prevent the
vehicle from moving .
(l) Tips
- Before changing the wheel, you must ac­
tivate the jacking mode, so that the au­
tomatic controls for the Adaptive Air
Suspension* do not make it more diffi­
cult to lift the vehicle with the jack
