remain continuously illuminated. This se
quence will continue upon subsequent vehicle
start-ups as long as the malfunction exists.
When the malfunction indicator is ill uminat
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 installat ion 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
tellta le after replacing one or more t ires or
wheels on your veh icle 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 indi cator 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 t ire tread circum
ference and vibration characteris tics of the in
dividual tires. If the pressure decreases in one
or more tires, this is indicated in the i nstru- ment
cluster with a warning symbol
RE and a
message
c:> fig. 205 .
The tire pressure monitoring system must be
reset via MMI each time the p ress ures are ad
justed (e.g . when switching between partial
and full load pressure) or after changing or re
plac ing a tire on your vehicle

TPMS indicator only monitors the tire pres

find the recommended tire pressures for your
vehicle on the Label on dr iver's side 8-pillar

Tire tread circumference and vibrat ion charac
teristics can change and cause a tire pressure
wa rning if:
- the t ire 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
