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
TP
MS malfunction indicator to indicate
when the system is not operating properly.
When the system detects a malfunction, the
telltale will flash for approximately one
minute and then remain continuously illumi
-
nated. This sequence will continue upon
s
u
bsequent 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, including the instal
-
lation of replacement or alternate tires or
wh
eels on the vehicle that prevent the TPMS
from functioning properly. Always check the
TPMS malfunction 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 properly.
System Error Activation
When the warning light flashes, there may
be a system malfunction. Contact an autho-
rized dealer.
A system error activation may occur in the
f
o
llowing cases:
When there is equipment or a device near
the vehicle using the same radio
frequency as that of the tire pressure
sensors.
When a metallic device such as a
non-genuine navigation system is
equipped near the center of the dash
-
board, which may block radio signals from
th
e tire pressure sensor to the receiver
unit.
When using the following devices in the
vehicle that may cause radio interference
with the receiver unit.
A digital device such as a personal
computer.
A current converter device such as a
DC-AC converter.
When excess snow or ice adheres to the
vehicle, especially around the wheels.
When the tire pressure sensor batteries are
discharged.
When using a wheel with no tire pressure
sensor installed.
When using tires with steel wire reinforce-
ment in the side walls.
When using tire chains.
Tires And Wheels
NOTE:
When inspecting or adjusting the tire air
p
r
essures, do not apply excessive force to the
stem portion of the wheel unit. The stem
portion could be damaged.
Changing Tires And Wheels
The following procedure allows the TPMS to
re
cognize a tire pressure sensor's unique ID
signal code whenever tires or wheels are
changed, such as changing to and from
winter tires.
