Tire Pressure Monitoring System (TPMS)
If there is a problem with the TPMS,
the tire pressure monitor shows a
''SYSTEM FUNCTION ERROR''
message and the tire pressure
readings are not displayed. If this
happens, you will first see a system
warning message ''CHECK TPMS
SYSTEM'' on the multi-information
display.

TPMS System Failure
If there is a problem with the TPMS,
you will see the above message on
the multi-information display.
If you see this message, the system
is off and is not monitoring the tire
pressures. Have the system checked
by your dealer as soon as possible.
Also, the low tire pressure/TPMS
indicator begins to flash (see page
69 ).
If the low tire pressure/TPMS
indicator comes on, or the multi-
information display shows a
''CHECK TPMS SYSTEM'' message,
the VSA system automatically turns
on even when the VSA system is
turned off by pressing the VSA OFF
switch (see page 313 ). If this
happens, you cannot turn the VSA
system off by pressing the VSA OFF
switch again.
When you restart the vehicle with
the compact spare tire, the TPMS
system message will also be
displayed on the multi-information
display after several miles
(kilometers) driving.
