TIRE PRESSURE MONITORING
SYSTEM (TPMS)
The Tire Pressure Monitor System (TPMS) will
warn the driver of a low tire pressure based on
the vehicle recommended cold placard pres-
sure.
The tire pressure will vary with temperature by
about 1 psi (7.0 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 maxi-
mum inflation pressure molded into the tire
sidewall. Refer to “Tires – General Information”
in “Starting And Operating” for information 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
pressure if the tire pressure falls below thelow-pressure warning limit for any reason, in-
cluding low temperature effects, or natural pres-
sure 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 (Tire Pres-
sure Monitoring Telltale Light) illuminates, you
must increase the tire pressure to the recom-
mended cold placard pressure in order for the
Tire Pressure Monitoring Telltale Light to turn
off. The system will automatically update and
the Tire Pressure Monitoring Telltale Light will
turn off once the system receives the updated
tire pressures.
NOTE:
When filling warm tires, the tire pressure
may need to be increased up to an additional
4 psi (30 kPa) above the recommended cold
placard pressure in order to turn the Tire
Pressure Monitoring Telltale Light off.
The vehicle may need to be driven for up to 10
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)
placard 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 (158
kPa). This tire pressure is sufficiently low
enough to turn ON the Tire Pressure Monitoring
Telltale Light. Driving the vehicle may cause the
tire pressure to rise to approximately 27 psi (186
kPa), but the Tire Pressure Monitoring Telltale
Light will still be ON. In this situation, the Tire
Pressure Monitoring Telltale Light will turn OFF
only after the tires are inflated to the vehicle’s
recommended cold placard pressure value.
NOTE:
When filling warm tires, the tire pressure
may need to be increased up to an additional
4 psi (30 kPa) above the recommended cold
placard pressure in order to turn the Tire
Pressure Monitoring Telltale Light off.

CAUTION!
•The TPMS has been optimized for the
original equipment tires and wheels. TPMS
pressures and warning have been estab-
lished 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. Af-
ter using an aftermarket tire sealant it is
recommended that you take your vehicle
to an authorized dealership to have your
sensor function checked.
•After inspecting or adjusting the tire pres-
sure always reinstall the valve stem cap.
This will prevent moisture and dirt from
entering the valve stem, which could dam-
age the TPMS sensor.NOTE:
•The TPMS is not intended to replace nor-
mal tire care and maintenance or to pro-
vide warning of a tire failure or condition.
•The TPMS should not be used as a tire
pressure gauge while adjusting your tire
pressure.
•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 maintenance, 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 pressure, 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 Receiver 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 compo-
nents:
•Receiver Module.
•Four Tire Pressure Monitoring Sensors.
•Tire Pressure Monitoring Telltale Light.
205

Tire Pressure Monitoring Low Pressure
Warnings
The Tire Pressure Monitoring Telltale Light will
illuminate in the instrument cluster, a LOW TIRE
message will be displayed for a minimum of five
seconds, and an audible chime will be activated
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 recom-
mended cold placard pressure value. The sys-
tem will automatically update and the Tire Pres-
sure Monitoring Light will extinguish and the
LOW TIRE message will turn off once the
updated tire pressures have been received.
NOTE:
When filling warm tires, the tire pressure
may need to be increased up to an additional
4 psi (30 kPa) above the recommended cold
placard pressure in order to turn the Tire
Pressure Monitoring Telltale Light off.
The vehicle may need to be driven for up to 10
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
system fault will also sound a chime. 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 is 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 and
LOW TIRE message will still turn ON due to
the low tire.
3. However, after driving the vehicle for up to
10 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. 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.

WARNING!
Improper towing can lead to an injury acci-
dent. Follow these guidelines to make your
trailer towing as safe as possible:
•Make certain that the load is secured in the
trailer and that it will not shift during travel.
When trailering cargo that is not fully se-
cured, dynamic load shifts can occur that
may be difficult for the driver to control. You
could lose control of your vehicle and have
an accident.
•All trailer hitches should be professionally
installed on your vehicle.
•When hauling cargo or towing a trailer, do
not overload your vehicle or trailer. Over-
loading can cause a loss of control, poor
performance, or damage to brakes, axle,
engine, transmission, steering, suspen-
sion, chassis structure, or tires.
(Continued)
WARNING!(Continued)
•Safety chains must always be used be-
tween your vehicle and trailer. Always con-
nect the chains to the frame or hook re-
tainers of the vehicle hitch. Cross the
chains under the trailer tongue and allow
enough slack for turning corners.
•Vehicles with trailers should not be parked
on a grade. When parking, apply the park-
ing brake on the tow vehicle. Always, block
or"chock"the trailer wheels.
•GCWR must not be exceeded.
•Total weight must be distributed be-
tween the tow vehicle and the trailer
such that the following four ratings are
not exceeded:
1. GVWR
2. GTW
3. GAWR
4. Tongue weight rating for the trailer hitch
utilized.Towing Requirements — Tires
•Do not attempt to tow a trailer while using a
compact spare tire.
•Proper tire inflation pressures are essential
for the safe and satisfactory operation of your
vehicle. Refer to “Tires – General Informa-
tion” in “Starting and Operating” for proper
tire inflation procedures.
•Check the trailer tires for proper tire inflation
pressures before trailer usage.
•Check for signs of tire wear or visible tire
damage before towing a trailer. Refer to
“Tires – General Information” in “Starting and
Operating” for the proper inspection
procedure.
•When replacing tires, refer to “Tires – Gen-
eral Information” in “Starting and Operating”
for proper tire replacement procedures. Re-
placing tires with a higher load carrying ca-
pacity will not increase the vehicle’s GVWR
and GAWR limits.

hicle.”CAUTION!
•The metal end fitting from Power Plug (8)
may get hot after use, so it should be
handled carefully.
•Failure to reinstall the cap on the fitting at
the end of the Sealant Hose (6) can result
in sealant contacting your skin, clothing,
and the vehicle’s interior. It can also result
in sealant contacting internal Tire Service
Kit components which may cause perma-
nent damage to the kit.
(D) Drive Vehicle:
Immediately after injecting sealant and inflating
the tire, drive the vehicle 5 miles (8 km) or 10
minutes to ensure distribution of the Tire Ser-
vice Kit Sealant within the tire. Do not exceed
55 mph (90 km/h).
