Among other possible causes, the
polyVbelt could be broken. Do not continue
to drive. Otherwise, the engine will overheat
due to an inoperative water pump which may
result in damage to the engine.
When the system detects a malfunction,
the telltale will flash for approximately
1 minute and then remain continuously
illuminated.
This sequence will continue upon subse
quent vehicle startups as long as the
malfunction exists. When the malfunction
indicator is illuminated, the system may
not be able to detect or signal low tire
pressure as intended.
TPMS malfunctions may occur for a vari
ety of reasons, including the installation
of incompatible replacement or alternate
tires or wheels on the vehicle that pre
vent the TPMS from functioning properly.
Always check the TPMS malfunction tell
tale after replacing one or more tires or
wheels on your vehicle to ensure that the
replacement or alternate tires and
wheels allow the TPMS to continue to
function properly.

Driving when your engine is overheated
can cause some fluids, which may have
leaked into the engine compartment, to
catch fire. You could be seriously burned.
Turn off the engine, get out of the vehicle
and do not stand near the vehicle until
the engine has cooled down.
