266 Tires and wheels
When the malfunction indicator is illuminat-
ed, the system may not be able to detect or
signal low tire pressure as intended. 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 funct ioning
properly . Always check the TPMS malfunction
telltale after replacing one or more t ires 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 monitor ing 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, th is is indicated in the instru-
ment cluster with a warning symbol
[9] and a
message
<=>fig. 219. The driver message in the
display goes out after 5 seconds. The driver
message can be displayed again by pressing
the
ISETI button. If only one tire is affected ,
the display will indicate its position.
The tire pressure monitoring must be reset via
radio or 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 <=>
page 267. You
can find the recommended tire pressures for
your vehicle on the label on driver 's side B-pil-
lar
<=> page 251.
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
<=> page 267 .

Check the tire or tires and replace or repair if
necessary. The indicator light

_&, WARNING
-
- If the tire pressure indicator appears in
the instrument cluster display, one or
more of your tires is significantly under-
inflated . Reduce your speed immediately
and avoid any hard steering or braking
maneuvers. Stop as soon as possible and
check the tires and their pressures. In-
flate the tire pressure to the proper pres-
sure as indicated on the vehicle's tire
