According ly, when the low tire pressure te ll­
tale illuminates, you shou ld stop and check
your tires as soon as possible, and inf late
them to the proper pressure. Driving on a s ig­
n ificantly under-inflated tire causes the tire to
overheat and can lead to tire failure. Under-in­
flation also reduces fuel efficiency and tire
tread life, and may affect the vehicle's han­
dli ng and stopp ing ability.
Please note that the TPMS is not a subst itute
for proper tire maintenance, and it is the driv­
e r's responsib ility to ma inta in correct tire
p ressu re, even if under- inflation has not
reached the leve l to trigger ill umination of the
TPMS low tire pressure telltale.
Your veh icle has also been equ ipped with a
TPMS malfunction indicato r to indica te when
the system is not opera ting properly. The
TPMS mal function indicator is combined wi th
the low tire press ure telltale . When the sys­
tem detects a malfunction, the te lltale will
f lash fo r approximately one minute and then
remain cont inuous ly illuminated. This se­
quence will continue upon subsequen t vehicle
start -ups as long as the ma lfunction ex ists .
When the malfunct ion indicator is ill uminat­
ed, the system may not be able to detect or
signal low t ire pressure as intended . TPMS
malfunctions may occur for a variety of rea ­
sons , includ ing the installat ion of replace­
ment or a lternate tires or whee ls on the veh i­
cle that prevent the TPMS from funct ioning
p roperly. Always check the TPM S malf unct ion
tellta le after replacing one o r more t ires or
wheels on your veh icle to ensure that the re­
p lacement or a lternate tires and wheels allow
the TPMS to continue to function p roperly. Tire pressure indicator appears

The tire pressure indicator in the instrument
cluster informs you if the tire pressure is too
low or if there is a system malfunction .

U sing the ABS sensors, the tire pressure moni­
toring system compares the tire tread circum ­
ference and vib ration characteristics of the in­
dividua l tires.
If the pressure decreases in one
or more t ires, this is indicated in the instru­
ment cluster with a
RI] war ning symbol and a
message ¢
fig. 187 . The driver message in the
display goes out afte r 5 seconds . The driver
message can b e displayed again by pressing
t h e
ISE TI button. If o nly one t ire is affec ted,
the d isp lay w ill indicate its posi tion.
The tire pressure monitoring system must be reset via rad io or M MI* each time the pres­
su res a re adjusted (e.g. when swit ching be­
tween partial and f ull load p ress ure) or after
changing or rep lacing a tire on your ve hicle

tors the ti re pressure that yo u have previous ly
stored. You can find the recommended tire
pressures for your vehicle on the label on driv­
er 's side 8-pillar ¢

Tire tread circumference and vibration charac­
teristics can change and cause a ti re pressure

- the tire press ure in one or more tires is too
low,
- the t ire has struc tural damage,
- t he t ire p ress ure was c hanged, wheels rota t-
ed or rep laced but the TPMS was not reset
