Handling the Unexpected
If you replace a flat tire with the comp act spare tire, the low tire pressure/TPMS
indicator comes on while you are driving. A fter driving for a few miles (kilometers),
Tire Pressure Monitor Problem will appear on the multi-information display and
the indicator will start blinki ng for a short time and then stay on; however, this is
normal and is no cause for concern.
If you replace the tire with a full-size tire, the warning message on the multi-
information display and the low tire pressu re/TPMS indicator will go off after a few
miles (kilometers).
■TPMS with Tire Fill Assist and the Compact Spare Tire1 TPMS with Tire Fill Assist and the Compact Spare Tire
The system cannot monitor the pressure of the
compact spare tire. Manually check the compact
spare tire pressure to be sure that it is correct.
Use the TPMS specific wheels. Each is equipped with
a tire pressure sensor mount ed inside the tire behind
the valve stem.

Handling the Unexpected
If the Low Tire Pressure/TPMS Indicator Comes On or
Blinks
■Reasons for the indicator to come on or blink
A tire pressure is significantly low.
If there is a problem with the TPMS with Tire Fill Assist, the indicator
blinks for about one mi nute, and then stays on.
If the compact spare tire is installed, the indicator will either come on or
it will first blink for abou t one minute, then stay on.
■What to do when the indicator comes on
Drive carefully and avoid abrupt cornering and hard braking.
Stop your vehicle in a safe place. Ch eck the tire pressure and adjust the
pressure to the specified level. The sp ecified tire pressure is on a label on
the driver side doorjamb.
If the compact spare tire causes the indicator to come on, change the
tire to a full-size tire.
■What to do when the indica tor blinks, then remains on
Have the tire inspected by a dealer as soon as possible. If the compact
spare tire causes the indicator to firs t blink, and then stay on, change the
tire to a full-size tire. The indicator goes off after driving for a few miles
(kilometers).
