Tire pressure monitoring system
5-32 Features and controls
5
Driving on a significantly under-inflated tire
causes the tire to overheat and can lead to tire
failure.
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 telltale.
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 min-
ute 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 illumi-
nated, the system may not be able to detect or
signal low tire pressure as intended.
TPMS malfunctions may occur for a variety
of reasons, including the installation of
replacement or alternate tires or wheels on the
vehicle that prevent the TPMS from function-
ing properly. Always check the TPMS mal-
function telltale after replacing 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 prop-
erly.

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
9-10.
2. If the tire pressure monitoring system
warning light remains illuminated after
you have been driving for about 20 min-
utes after you adjust the tire inflation pres-
sure, 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.
If the warning light illuminates
while driving
NOTE
 When inspecting or adjusting the tire pres-
sure, to avoid breakage, do not apply exces-
sive force to the valve stem.
 After inspecting or adjusting the tire pres-
sure, 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 sen-
sors.
 Once adjustments have been made, the warn-
ing light will go off after a few minutes of
driving.
WARNING
 If the tire pressure monitoring system
warning light illuminates while you are
driving, avoid hard braking, sharp steer-
ing maneuvers and high speeds. Driving
with an under-inflated tire adversely
affects vehicle performance and can result
in an accident.
CAUTION

The tire pressure monitoring system warning
light may not illuminate immediately in the
event of a tire blowout or rapid leak.
NOTE

To avoid the risk of damage to the tire infla-
tion pressure sensors, have any punctured
tire repaired by a certified i-MiEV dealer. If
the tire repair is not done by a certified i-
MiEV dealer, it is not covered by your war-
ranty.
