La operación de este equipo está sujeta a las
siguientes dos condiciones:
1. es posible que este equipo o dispositivo no
cause interferencia perjudicial y
2. este equipo o dispositivo debe aceptar
cualquier interferencia, incluyendo la que
pueda causar su operación no deseada.
NOTE:
Changes or modifications not expressly approved
by the party responsible for compliance could
void the user’s authority to operate the equip-
ment.
Tire Pressure Monitoring System (TPMS)
The Tire Pressure Monitoring System (TPMS)
will warn the driver of a low tire pressure based
on the vehicle recommended cold tire pressure.
The tire pressure will vary with temperature by
about 1 psi (7 kPa) for every 12°F (6.5°C). This
means that when the outside temperature
decreases, the tire pressure will decrease. Tire
pressure should always be set based on cold
inflation tire pressure. This is defined as the tire
pressure after the vehicle has not been driven
for at least three hours, or driven less than
1 mile (1.6 km) after a three hour period. The
cold tire inflation pressure must not exceed the
maximum inflation pressure molded into the
tire sidewall. Refer to “Tires – General Informa-
tion” in “Servicing And Maintenance” for infor-
mation on how to properly inflate the vehicle’s
tires. The tire pressure will also increase as the
vehicle is driven, this is normal and there should
be no adjustment for this increased pressure.
The TPMS will warn the driver of a low tire pres-
sure if the tire pressure falls below the low pres-
sure warning limit for any reason, including low
temperature effects, or natural pressure loss
through the tire.
The TPMS will continue to warn the driver of low
tire pressure as long as the condition exists,
and will not turn off until the tire pressure is at
or above the recommended cold tire pressure
on the placard. Once the low tire pressure
warning (Tire Pressure Monitoring Warning
Light) illuminates, you must increase the tire
pressure to the recommended cold tire pres-
sure in order for the Tire Pressure Monitoring
Warning Light to turn off. The system will auto-
matically update and the Tire Pressure Moni-
toring Warning Light will turn off once the
system receives the updated tire pressures. The
vehicle may need to be driven for up to
20 minutes above 15 mph (24 km/h) in order
for the TPMS to receive this information.
For example, your vehicle may have a recom-
mended cold (parked for more than three
hours) tire pressure of 30 psi (207 kPa). If the
ambient temperature is 68°F (20°C) and the
measured tire pressure is 27 psi (186 kPa), a
temperature drop to 20°F (-7°C) will decrease
the tire pressure to approximately 23 psi
(159 kPa). This tire pressure is sufficiently low
enough to turn on the Tire Pressure Monitoring
Warning Light. Driving the vehicle may cause
the tire pressure to rise to approximately 27 psi
(186 kPa), but the Tire Pressure Monitoring
Warning Light will still be on. In this situation,
the Tire Pressure Monitoring Warning Light will
turn off only after the tires are inflated to the
vehicle’s recommended cold tire pressure
value.
