Each tire, including the spare (if provided), should be checked
monthly when cold and inflated to the inflation pressure rec-
ommended by the vehicle manufacturer on the vehicle placard
or tire inflation pressure label. (If your vehicle has tires of a
different size than the size indicated on the vehicle placard or
tire inflation pressure label, you should determine the proper
tire inflation pressure for those tires.)
As an added safety feature, your vehicle has been equipped
with a tire pressure monitoring system (TPMS) that illuminates
a low tire pressure telltale when one or more of your tires is
significantly under-inflated.
Accordingly, when the low tire pressure telltale illuminates,
you should stop and check your tires as soon as possible, and
inflate them to the proper pressure.
Driving on a significantly under-inflated tire causes the tire to
overheat and can lead to tire failure.
If a malfunction is detected in the tire pressure mon-
itoring system, the tire pressure monitoring system
warning light will blink for approximately 1 minute
and then remain continuously illuminated. The
warning light will issue further warnings each time
the electric motor unit is restarted as long as the
malfunction exists.
Check to see whether the warning light goes off after
few minutes of driving.
If it then goes off during driving, there is no prob-
lem.
However, if the warning light does not go off, or if it
blinks again when the electric motor unit is
restarted, have the vehicle inspected by a certified i-
MiEV dealer.
In such situations, a malfunctioning of the system
may be preventing the monitoring of the tire pres-
sure. For safety reasons, when the warning light
appears while driving, avoid sudden braking, sharp
turning and high-speed driving.

Under-inflation also reduces alternative fuel efficiency and tire
tread life, and may affect the vehicle’s handling and stopping
ability.
Please note that the TPMS is not a substitute for proper tire
maintenance, and it is the driver’s responsibility to maintain
correct tire pressure, even if under-inflation has not reached the
level to trigger illumination of the TPMS low tire pressure tell-
tale.
Your vehicle has also been equipped with a TPMS malfunction
indicator to indicate when the system is not operating properly.
The TPMS malfunction indicator is combined with the low tire
pressure telltale.
When the system detects a malfunction, the telltale will flash
for approximately one minute and then remain continuously
illuminated. This sequence will continue upon subsequent
vehicle start-ups 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 variety of reasons, includ-
ing the installation of replacement or alternate tires or wheels
on the vehicle that prevent the TPMS from functioning prop-
erly. Always check the TPMS malfunction telltale after replac-
ing 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.

1. If the low tire pressure monitoring system warning light
illuminates, avoid hard braking, sharp steering maneuvers
and high speeds. You should stop and adjust the tires to
the proper inflation pressure as soon as possible. Refer to
“Tires” on page 7-18.NOTEWhen inspecting or adjusting the tire pressure, to avoid
breakage, do not apply excessive force to the valve stem.
After inspecting or adjusting the tire pressure, always
reinstall the valve cap on the valve stem.
Without the valve cap, dirt or moisture could get into the
valve, resulting in damage to the tire inflation pressure
sensor.
Do not use metal valve caps, which may cause a metal
reaction, resulting in corrosion and damage of the tire
inflation pressure sensors.
Once adjustments have been made, the warning light will
go off after a few minutes of driving.
2. If the tire pressure monitoring system warning light
remains illuminated after you have been driving for about
20 minutes after you adjust the tire inflation pressure, one
or more of the tires may have a puncture. Inspect the tire
and if it has a puncture, have it repaired by a certified i-
MiEV dealer as soon as possible.
