automatically update and the TPM Telltale 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 recommended
cold (parked for more than three hours) placard pres-
sure 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 (158 kPa). This
tire pressure is sufficiently low enough to turn ON the
TPM Telltale Light. Driving the vehicle may cause the
tire pressure to rise to approximately 27 psi (186 kPa),
but the TPM Telltale Light will still be ON. In this
situation, the TPM Telltale Light will turn OFF only
after the tires are inflated to the vehicle’s recommended
cold placard pressure value.
CAUTION!
The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures and
warnings have been established for the tire size

equipped on your vehicle. Undesirable system
operation or sensor damage may result when
using replacement equipment that is not of the
same size, type, and/or style. Aftermarket wheels
can cause sensor damage. Using aftermarket tire
sealants may cause the Tire Pressure Monitoring
System
(TPMS)
sensor
to
become
inoperable.
After using an aftermarket tire sealant it is recom-
mended that you take your vehicle to an autho-
rized dealer to have your sensor function checked.
After inspecting or adjusting the tire pressure,
always reinstall the valve stem cap. This will
prevent moisture and dirt from entering the valve
stem,
which
could
damage
the
Tire
Pressure
Monitoring Sensor.
NOTE:
The TPMS is not intended to replace normal tire care
and maintenance, or to provide warning of a tire
failure or condition.
The TPMS should not be used as a tire pressure
gauge while adjusting your tire pressure.

SAFETY
97
Driving on a significantly under-inflated tire causes
the tire to overheat and can lead to tire failure.
Under-inflation also reduces fuel efficiency and tire
tread life, and may affect the vehicle’s handling and
stopping ability.
The TPMS is not a substitute for proper tire mainte-
nance, and it is the driver’s responsibility to maintain
correct tire pressure using an accurate tire gauge,
even if under-inflation has not reached the level to
trigger illumination of the Tire Pressure Monitoring
Telltale Light.
Seasonal temperature changes will affect tire pres-
sure, and the TPMS will monitor the actual tire
pressure in the tire.
Base System
This is the TPMS warning indicator located in
the instrument cluster.
The TPMS uses wireless technology with wheel rim
mounted electronic sensors to monitor tire pressure
levels. Sensors, mounted to each wheel as part of the
valve stem, transmit tire pressure readings to the Re-
ceiver Module.
NOTE:
It is particularly important for you to check the
tire pressure in all of the tires on your vehicle regularly
and to maintain the proper pressure.
The TPMS consists of the following components:
Receiver Module.
Four Tire Pressure Monitoring Sensors.
Tire Pressure Monitoring Telltale Light.
Tire Pressure Monitoring Low Pressure Warnings
The Tire Pressure Monitoring Telltale Light will illumi-
nate in the instrument cluster, an acoustic signal will be
activated, and the “Check left or right front/rear tire”
text message will display when one or more of the four
active road tire pressures are low. Should this occur, you
should stop as soon as possible, check the inflation
pressure of each tire on your vehicle, and inflate each
tire to the vehicle’s recommended cold placard pressure
value. The system will automatically update and the
98
SAFETY
Tire Pressure Monitoring Light will extinguish once the
updated tire pressures have been received. The vehicle
may need to be driven for up to 20 minutes above
15 mph (24 km/h) to receive this information.
Check TPMS Warnings
The Tire Pressure Monitoring Telltale Light will flash on
and off for 75 seconds and remain on solid when a
system fault is detected, the “TIRE PRESSURE MONI-
TORING UNAVAILABLE” text message will display. If
the ignition key is cycled, this sequence will repeat
providing the system fault still exists. The Tire Pressure
Monitoring Telltale Light will turn off when the fault
condition no longer exists. A system fault can occur
with any of the following scenarios:
1. Jamming due to electronic devices or driving next to
facilities emitting the same radio frequencies as the
TPM sensors.
2. Installing some form of aftermarket window tinting
that affects radio wave signals.
3. Snow or ice around the wheels or wheel housings.
4. Using tire chains on the vehicle.
5. Using wheels/tires not equipped with TPM sensors.
NOTE:
Your vehicle may be equipped with a compact
spare wheel and tire assembly.
1. The compact spare tire does not have a tire pressure
monitoring sensor. Therefore, the TPMS will not
monitor the tire pressure in the compact spare tire.
2. If you install the compact spare tire in place of a road
tire that has a pressure below the low-pressure
warning limit, upon the next ignition key cycle, a
chime will sound and the Tire Pressure Monitoring
Telltale Light will still turn ON due to the low tire.
3.
However, after driving the vehicle for up to 20 minutes
above 15 mph (24 km/h), the Tire Pressure Monitoring
Telltale Light will flash on and off for 75 seconds and
then remain on solid.
4. This occurs for each subsequent ignition key cycle, a
chime will sound and the Tire Pressure Monitoring
Telltale Light will flash on and off for 75 seconds and
then remain on solid.

5. Once you repair or replace the original road tire and
reinstall it on the vehicle in place of the compact
spare tire, the TPMS will update automatically and
the Tire Pressure Monitoring Telltale Light will turn
OFF, as long as no tire pressure is below the low-
pressure warning limit in any of the four active road
tires. 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.
General Information
This device complies with Part 15 of the FCC rules and
RSS-210 of Industry Canada. Operation is subject to the
following two conditions:
(1) This device may not cause harmful interference.

OCCUPANT RESTRAINT SYSTEMS
Some of the most important safety features in your
vehicle are the restraint systems:
Occupant Restraint Systems Features
Seat Belt Systems
Supplemental Restraint Systems (SRS) Air Bags
Child Restraints
Some of the safety features described in this section
may be standard equipment on some models, or may be
optional equipment on others. If you are not sure, ask
your authorized dealer.
Important Safety Precautions
Please pay close attention to the information in this
section. It tells you how to use your restraint system
properly, to keep you and your passengers as safe as
possible.
Here are some simple steps you can take to minimize
the risk of harm from a deploying air bag:
1. Children 12 years old and under should always ride
buckled up in a vehicle with a rear seat.
