appear on the multi-information display an d the indicator will start blinking for a
short time and then stay on; however, this is normal and is no cause for concern.

information display and the low tire pressu re/TPMS indicator will go off after a few
miles (kilometers).
■TPMS and the Compact Spare Tire1 TPMS and the Compact Spare Tire
The system cannot monitor th e pressure of the spare
tire. Manually check the spare tire pressure to be sure
that it is correct.
Use the TPMS specific wheels. Each is equipped with

uuIndicator, Coming On/Blinking uIf the Low Tire Pressure/TPMS Indicator Comes On or Blinks
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, the indicator blinks for about one
minute, 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 indicator blinks
Have the tire inspected by a dealer as soon as possible. If the compact
spare tire
* causes the indicator to first b link, and then stay on, change
the tire to a full-size tire. The indi cator goes off after driving for a few
miles (kilometers).

NOTICE
Driving on an extremely underinflated tire can cause
it to overheat. An overheated tire can fail. Always
inflate your tires to the prescribed level.
TPMS with Tire Fill Assist provides visual and audible
assistance during tire pre ssure adjustment. With the
power mode in ON and transmission in
( P, while you
adjust tire pressure up or down, the system alerts you
as follows:
Below recommended pressure: The beeper
sounds and exterior lights flash once every five
seconds.
At recommended pressure: The beeper sounds
and exterior lights flash ra pidly for three seconds with
five seconds intervals.
Above recommended pressure: The beeper
sounds and lights flash tw ice every two seconds.
When a certain amount of time has passed since
activation, Tire Fill Assist wi ll be canceled until you set
the power mode to OFF.
You cannot use Tire Fill Assist if the engine was
started by the remote engine start, or if there is a
malfunction in the system.
If Tire Fill Assist does not work, use a tire pressure
gauge.
