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 tirefailure. Under-inflation also re
duces alternative fuel
efficiency and tire tread life, and may affectthe vehicle’s handling and stopping ability. Please note that the TP
MS is not a substitute
for proper tire mainte
nance, and it is the
driver’s responsibility to maintain correct tire pressure, even if under-inflation has not reached the level to tri
gger illumination of the
TPMS low tire pressure telltale. Your vehicle has also been equipped with a TPMS malfunction indicator to indicate whenthe 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 thevehicle 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 wheelsallow the TPMS to continue to function prop- erly.

1. If the low tire pressure monitoring system warning light illumi
nates, avoid hard
braking, sharp steering maneuvers and high speeds. You should stop and adjustthe 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 afteryou 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 adju
sting the tire pres-
sure, always reinstall the valve cap on the valve stem. Without the valve cap, dirt or moisture couldget 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.
WA R N I N G If the tire pressure monitoring system warning light illumi
nates while you are
driving, avoid hard br
aking, sharp steer-
ing maneuvers and high speeds. Drivingwith 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 cert
ified i-MiEV dealer. If
the tire repair is not done by a certified i- MiEV dealer, it is not
covered by your war-
ranty.
