Tire Pressure Monitoring System (TPMS)
For example, if you check and fill
your tires in a warm area, then drive
in extremely cold weather, the tire
pressure will be lower than
measured and could be underinflated
and cause the low tire pressure/
TPMS indicator to come on. Or, if
you check and adjust your tire
pressure in cooler conditions, and
drive into extremely hot conditions,
the tires may become overinflated.
However, the low tire pressure/
TPMS indicator will not come on if
the tires are overinflated.
Refer to page for tire inflation
314
guidelines.
If there is a problem with the TPMS,
this indicator begins to flash. It stops
flashing after approximately 1
minute, then stays on. You will also
see a ''CHECK TPMS SYSTEM''
message on the multi-information
display (see page 267 ).

Although your tire pressure is
monitored, you must manually check
the tire pressures monthly.
Each tire, including the spare, should
be checked monthly when the
vehicle is cold, and set to the
recommended inflation pressure as
specified on the vehicle placard and
in the owner's manual (see page
315 ).
