Tire Pressure Monitoring System (TPMS)
Changing a Tire with TPMS
If you have a flat tire, the low tire
pressure and tire monitor indicators
will come on. Replace the indicated
flat tire with the compact spare tire
(see page 277 ).
Each wheel is equipped with a tire
pressure sensor mounted inside the
tire behind the valve stem. You must
use TPMS specific wheels. It is
recommended that you always have
your tires serviced by your dealer or
a qualified technician.
After you replace the flat tire with
the spare, the TPMS indicator stays
on. This is normal; the system is not
monitoring the spare tire pressure.
Manually check the spare tire
pressure to be sure it is correct.
210
The low tire pressure indicator or
the TPMS indicator will go off when
you replace the spare tire with the
specified regular tire equipped with
the tire pressure monitor sensor.
Never use a puncture-repairing agent
in a flat tire. If used, you will have to
replace the tire pressure sensor.
Have the flat tire repaired by your
dealer as soon as possible.
