remain continuously illuminated. This se-
quence will continue upon subsequent vehicle
start-ups as long as the malfunction exists.
When the malfunction indicator is illuminat-
ed, the system may not be able to detect or
signal low tire pressure as intend ed. TPMS
malfunctions may occur for a variety of rea-
sons, including the installation of replace-
ment or alternate tires or wheels on the vehi-
cle 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 re-
placement or alternate tires and wheels allow
the TPMS to continue to function properly.
Tire pressure 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.

Using the ABS sensors, the tire pressure moni-
toring system compares the tire tread circum-
ference and vibration characteristics of the in-
dividual tires . If the pressure decreases in one
or more tires, this is indicated in the instru-
Tires and wheels 267
ment cluster with a warning symbol [I] and a
message
r::!)fig. 213.
The tire pressure monitoring system must be
reset via MMI each time the pressures are ad-
justed (e.g. when switching between partial
and full load pressure) or after changing or re-
placing a tire on your vehicle
r::!) pag e 268. The
TPMS indicator only monitors the tire pres-
sure that you have previously stored. You can
find the recommended tire pressures for your
vehicle on the label on driver's side 8-pillar
<=:>page 252 .
Tire tread circumference and vibration charac-
teristics can change and cause a tire pressure
warning if:
- the tire pressure in one or more tires is too
low,
- the tire has structural damage,
- the tire pressure was changed, wheels rotat-
ed or replaced but the TPMS was not reset
