Wheels
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 overheat 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
proper tire maintenance, and it is the driver's re
sponsibility to maintain correct tire pressure,
even if under-inflation has not reached the level
to trigger illumination of the TPMS low tire pres
sure telltale.
Your vehicle has also been equipped with a TPMS malfunction indicator to indicate when the sys
tem is not operating 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 minute and then remain continuously
illuminated. This sequence will continue upon
subsequent vehicle start-ups as long as the mal
function exists .
When the malfunction indicator is illuminated,
the system may not be able to detect or signal low tire pressure as intended . TPMS malfunctions
may occur for a variety of reasons, including the
installation of replacement or alternate tires or
wheels on the vehicle that prevent the TPMS from functioning properly . Always check the
TPMS malfunction telltale after replacing one or
more tires or wheels on your vehicle to ensure
that the replacement or alternate tires and
wheels allow the TPMS to continue to function
properly.

· If the Tire Pressure Monitoring System
indicator appears
Applies to vehicles: with tire pressure monitoring system
The tire pressure indicator in the instrument
cluster informs you if the tire pressure is too low
or if there is a system malfunction.
Fig. 208 Instrument cl uster: i ndic ator ligh t with message
Using the ABS sensors, the tire pressure monitor
ing system compares the tire tread circumfer
ence and vibration characteristics of the individu
al tires . If the pressure changes in one or more
tires , this is indicated in the instrument cluster
display with an indicator light
RE and a message
c>fig. 208. If only one tire is affected, the loca
tion of that tire will be indicated.
The tire pressures 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
c> page 253. The tire pressure moni
toring system only monitors the tire pressure you have stored. Refer to the tire pressure label for
the recommended tire pressure for your vehicle
c> page 244, fig . 207.
Tire tread circumference and vibration character
istics can change and cause a tire pressure warn
ing if:
- the tire pressure in one or more tires is too low.
- the tire has structural damage.
- the tire was replaced or the tire pressure was
changed and it was not stored

The onboard tool k it includes:
- Hook for removing wheel covers*
- Plastic hook to
remove wheel bolt covers*
-Alignment pin for changing wheels
- Wheel bolt wrench
- Folding chocks
- Screwdriver with revers ible blade
- Socket (removable Torx socket)*
- 10 x 13 open ended wrench (for disconnecting
the battery cables)
- Towing eye
A WARNING
Improper use of the vehicle jack* can cause
ser ious personal injuries.
- Never use the jack* supplied with your Aud i
on another vehicle, particularly on a heavier
one. The jack* is only su itable for use on the
vehicle it came w ith.
254 -
Using a bumper jack to raise the vehicle will
damage the bumper system. The jack may
slip, caus ing injury.
- Never support your vehicle on cinder blocks,
bricks or other objects. These may not be
able to support the load and could cause in
jury when they fail.
- Never start or run the engine while the vehi
cle is supported by the jack* .
- If you must work under the vehicle, always
use safety stands specifically designed for
this purpose .
- Never use the hexagonal socket in the han
dle of the screwdr iver to loosen or tighten
the wheel bolts .
- Always make sure the inflatable spare tire*
and
even a flat tire are secu red in place and
not loose, otherwise they could fly forward,
causing personal inj ury to passenge rs in the
