Tire Pressure Monitoring
System (AS, S8)
(D General notes
A ppl ies to: AS, 58
Each t ire, including the spare (if provided),
should be checked monthly when cold and inflat
ed to the inflation pressure recommended by the
veh icle manufact urer on the vehicle placard or
tire inflation pressure label. (If your vehicle has
tires of a different size than the size indicated on
the vehicle placard or tire inflation pressure la
be l, you should determine the proper tire infla
tion pressure for those tires).
As an added safety feature, your veh icle has been
equipped with a tire pressure monitoring system
(TPMS) that illuminates a low tire pressure te ll
tale when one or more of your tires is significant
ly under-inflated . Accordingly, when the low tire
pressure telltale illuminates, you should stop and
check your tires as soon as possible, and inflate
them to the proper pressure . Driving on a signifi
cantly under-inflated tire causes the tire to over
heat and can lead to tire failure. Under-inflation
also reduces fuel efficiency and tire tread life,
and may affect the vehicle's handling and stop
ping ability .
Please note that the TPMS is not a substitute for
p roper tire maintenance, and it is the driver's re
sponsib ility to ma intain correc t tire p ressure,
even if under-inflation has not reached the level
to trigger illumination of the TPMS low tire pres
sure telltale.
Your veh icle has also bee n eq uipp ed w ith a TPM S
mal function indicator to indicate when the sys
tem is not operat ing properly. The TPMS mal
function indicator is combined with the low tire
pressure telltale. When the system detects a
malfunction, the telltale will flash for approxi
mately one mi nute and then remain cont inuously
illuminated . This sequence will continue upon
Wheels
subsequent vehicle start-ups as long as the mal
function exists .
When the malfunction indicator is illuminated ,
the sys tem may not be able to detect or signal
low tire pressure as intended . TPMS malfunctions
may occur for a variety of reasons, including the
i nsta llation of replacement or alternate tires or
whee ls on the vehicle that prevent the TPMS
from functioning properly. Always check the
TPMS malfunction telltale after replac ing one or
more tires or wheels on your vehicle to ensure
that the replacement or a lternate tires and
whee ls allow the TPMS to continue to function
properly.
If the Tire Pressure Monitoring System
indicator appears
Applies to: A8, 58
The tire pressure indicator in the instrument
cluster informs you if the tire pressure is too low
or if there is a system malfunction.

Using the ABS sensors, the tire pressure monitor
ing system compares the tire tread c ircumfer
ence and vibration characteristics of the individu
al tires.
If the press ure changes in one or more
tires, this is indicated in the instrument cluster
display with an indicator light
[I] and a message.
If only one tire is affected, the location of that
tire will be indicated.
T he tire press ures must be stored in the Infotain
ment system again each time the pressures
change (switching between partial and full load
pressure) or after changing or replacing a tire on
your vehicle

toring system only monitors the tire pressure you have stored . Refer to the t ire pressure label for ..,.

- The factory-supplied jack is intended only
for your vehicle model. Under no circum
stances should it be used to lift heavy

Observe the following precautions for your own
and your passenger's safety when changing a
wheel .
.,. After you experience a tire fail ure, pull the car
well away from moving t raff ic and try to reach
le vel ground before you stop¢,&. .
.,. All passengers should
lea ve the ca r and move
to a safe location (for instance, behind the
guardrail) ¢,&. .

WARNING
You or your passengers co uld be injured while
chang ing a wheel if you do not follow these
safety precautions:
Em ergenc y ass is tanc e
-If you have a flat tire, move a safe distance
off the road. Turn off the eng ine, turn the
emergency flashers on and use other warn ing dev ices to alert other motorists .
- Make sure that passengers wait in a safe
p lace away from the vehicle and well away
from the road and traff ic .
- To help prevent the veh icle from moving
suddenly and possib ly slipping off the jack,
always fully set the park ing brake and block
the wheel d iagonally opposi te the wheel be
ing changed. When one front whee l is lifted
off the groun d, p lacing the Automatic
Transmission in "P" (Park) w ill
not prevent
the vehicle from mov ing.
- Before you change a wheel, be sure the
g round is leve l and firm. If necessary, use a
sturdy board under the jack .
- Always s tore the vehicle tool kit, the jack
and the replaced tire in the luggage com
partment

(D Tips
Befo re c hanging the w heel, you must activate
t he jacking mode, so that the a utomat ic co n
tro ls for the Adaptive Air Suspension do not
make it more difficult to lift the vehicle with
the jack
