Tires and wheels
TPMS malfunction indicato r is combined with
the low tire pressure telltale . When the sys-
tem detects a malfunct ion, the te ll tale will
flash for approximately one minute and then
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 t ire pressure as intended . TPMS
malfunctions may occur for a variety of rea-
sons, includ ing the installat ion of replace-
ment or alt ernate tires or whee ls on the vehi-
cle that prevent the TPMS from functioning
properly. Always check the TPMS malfunct ion
tellta le 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
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 tir e 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 instr u-
ment cluster with a
[D]
warning symbol and a
message ¢
fig. 254.
The driver message in the
display goes out after S seconds. The driver
message can be displayed again by pressing
the

I
button . If only one tire is affect-
ed, the display will indicate its position .
The tire pressure monitoring must be reset via
MMI each time the pressures are adjusted (e.
g. when switching between partial and fu ll
load pressure) or after changing or replacing a
tire on your vehicle ¢

The TPMS in-
dicator on ly monitors the tire pressure that
you have previously stored . You can find the
recommended t ire pressures for your vehicle
on the label on driver's side B-pillar

Tire tread circumference and vibration charac-
teristics can change and cause a tire pressure
warning if:
- the t ire pressure in one or more tires is too
low,
- the t ire has structural damage,
- the t ire pressure was changed, wheels rotat-
ed or replaced but the TPMS was not reset
