General Information
The following regulatory statement applies to all
Radio Frequency (RF) devices equipped in this
vehicle:
This device complies with Part 15 of the FCC
Rules and with Industry Canada license-exempt
RSS standard(s). Operation is subject to the
following two conditions:
1. This device may not cause harmful
interference.
2. This device must accept any interference
received, including interference that may
cause undesired operation.
NOTE:
Changes or modifications not expressly ap-
proved by the party responsible for compliance
could void the user’ s authority to operate the
equipment.
Tire Pressure Monitor System (TPMS)
The Tire Pressure Monitor System (TPMS) will
warn the driver of a low tire pressure based on the
vehicle recommended cold placard pressure.
NOTE:
The TPMS W arning Light will illuminate in the
instrument cluster and a chime will sound when
tire pressure is low in one or more of the four
active road tires. In addition, the instrument
cluster will display a graphic showing the pres-
sure values of each tire with the low tire pressure
values in a different color , when this occurs you
must increase the tire pressure to the recom-
mended cold placard pressure in order for the
TPMS W arning Light to turn off.
The tire pressure will vary with temperature by
approximately 1 psi (7 kPa) for every 12°F
(6.5°C). This means that when the outside tem-
perature decreases, the tire pressure will de-
crease. 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” in “Servicing
and Maintenance” for information on how to
properly inflate the vehicle’s tires.
The tire pressure will also increase as the ve-
hicle 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
pressure if the tire pressure falls below the
low-pressure warning limit for any reason, in-
cluding low temperature effects and 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 placard pressure.
Once the low tire pressure warning (TPMS
W arning Light) illuminates, you must increase
the tire pressure to the recommended cold plac-
ard pressure in order for the TPMS Warning
Light to turn off.
The system will automatically update and the
TPMS Warning Light will turn off once the
system receives the updated tire pressures. The
vehicle may need to be driven for up to 20 min-
utes above 15 mph (24 km/h) in order for the
TPMS to receive this information.
