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 pres-
sure 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 pres-
sure 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 the low-pressure 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 placard pressure. Once the low tire pressure warn-
ing (Tire Pressure Monitoring Telltale Light) illuminates,
you must increase the tire pressure to the recommended
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.

CAUTION!(Continued)
moisture and dirt from entering the valve stem,
which could damage the TPMS 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.
• 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 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 lev-
els. Sensors, mounted to each wheel as part of the valve
stem, transmit tire pressure readings to the Receiver
Module.
498 STARTING AND OPERATING
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, a LOW TIRE PRESSURE
message and “Inflate Tire to XX” message will be dis-
played 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 recommended cold placard pressure value. The recommended cold placard pressure value is
the pressure value in the
Inflate Tire to XXmessage
displayed in the EVIC/DID. The system will automati-
cally update and the Tire Pressure Monitoring Light will
extinguish and the LOW TIRE PRESSURE and “Inflate
Tire to XX” messages will turn off 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.
Service TPMS Warnings
The Tire Pressure Monitoring Telltale Light will flash on
and off for 75 seconds and then remain on solid when a
system fault is detected. The system fault will also sound
a chime and display a “SERVICE TPM SYSTEM” mes-
sage for a minimum of five seconds. If the ignition key is
cycled, this sequence will repeat providing the system
fault still exists. The Tire Pressure Monitoring Telltale

displayed in a different color. The recommended cold
placard pressure inflation value is the pressure value
displayed in theInflate Tire to XX message displayed in
the EVIC/DID.
Should a low tire condition occur on any of the four
active road tire(s), you should stop as soon as possible
and inflate all tires that are in a different color on the
graphic display to the vehicle’s recommended cold plac-
ard pressure value. The system will automatically up-
date, the “Inflate Tire to XX” message will no longer be
displayed, the graphic display of the pressure value(s)
will return to their normal color, and the Tire Pressure
Monitoring Light will extinguish once the updated tire
pressure(s) 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.Service TPMS Message
The Tire Pressure Monitoring Telltale Light will flash on
and off for 75 seconds, and then remain on solid when a
system fault is detected. The system fault will also sound
a chime. The EVIC/DID will display a “SERVICE TPM
SYSTEM” message for a minimum of five seconds. This
text message is then followed by a graphic display, with
“- -“ in place of the pressure value(s) indicating which
Tire Pressure Monitoring Sensor(s) is not being received.
If the ignition key is cycled, this sequence will repeat,
providing the system fault still exists. If the system fault
no longer exists, the Tire Pressure Monitoring Telltale
Light will no longer flash, the SERVICE TPM SYSTEM
message will not be present, and a pressure value will be
displayed instead of dashes. A system fault can occur
with any of the following scenarios:
502 STARTING AND OPERATING
Gross Vehicle Weight Rating (GVWR)
The GVWR is the total allowable weight of your vehicle.
This includes driver, passengers, and cargo. The total
load must be limited so that you do not exceed the
GVWR.
Tire Size
The tire size on the Vehicle Certification Label represents
the actual tire size on your vehicle. Replacement tires
must be equal to the load capacity of this tire size.
Rim Size
This is the rim size that is appropriate for the tire size
listed.
Inflation Pressure
This is the cold tire inflation pressure for your vehicle for
all loading conditions up to full GAWR.
Curb Weight
The curb weight of a vehicle is defined as the total weight
of the vehicle with all fluids, including vehicle fuel, at full
capacity conditions, and with no occupants or cargo loaded
into the vehicle. The front and rear curb weight values are
determined by weighing your vehicle on a commercial
scale before any occupants or cargo are added.
Overloading
The load carrying components (springs, tires, wheels,
etc.) of your vehicle will provide satisfactory service as
long as you do not exceed the GVWR.
The best way to figure out the total weight of your
vehicle is to weigh it when it is fully loaded and ready for
operation. Weigh it on a commercial scale to ensure that
it is not over the GVWR.

Towing Requirements — Tires
•Do not attempt to tow a trailer while using a compact
spare tire.
• Proper tire inflation pressures are essential to the safe
and satisfactory operation of your vehicle. Refer to
“Tires – General Information” in “Starting And Oper-
ating” for proper tire inflation procedures.
• Check the trailer tires for proper tire inflation pres-
sures 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 – General Infor-
mation” in “Starting And Operating” for proper tire replacement procedures. Replacing tires with a higher
load carrying capacity will not increase the vehicle’s
GVWR and GAWR limits.
Towing Requirements — Trailer Brakes
•
Do not interconnect the hydraulic brake system or
vacuum system of your vehicle with that of the trailer.
This could cause inadequate braking and possible
personal injury.
• An electronically actuated trailer brake controller is
required when towing a trailer with electronically
actuated brakes. When towing a trailer equipped with
a hydraulic surge actuated brake system, an electronic
brake controller is not required.
• Trailer brakes are recommended for trailers over
1,000 lbs (450 kg) and required for trailers in excess of
2,000 lbs (907 kg).
522 STARTING AND OPERATING
NOTE:If the Mode Select Knob (5) is on Air Mode and
the pump is operating, air will dispense from the Air
Pump Hose (7) only, not the Sealant Hose (6).
If the sealant (white fluid) does flow through the
Sealant Hose (6):
1. Continue to operate the pump until sealant is no longer flowing through hose (typically takes 30 - 70
seconds). As the sealant flows through the Sealant
Hose (6), the Pressure Gauge (3) can read as high as 70
psi (4.8 Bar). The Pressure Gauge (3) will decrease
quickly from approximately 70 psi (4.8 Bar) to the
actual tire pressure when the Sealant Bottle (1) is
empty.
2. The pump will start to inject air into the tire immedi- ately after the Sealant Bottle (1) is empty. Continue to
operate the pump and inflate the tire to the pressure
indicated on the tire pressure label on the driver-side latch pillar (recommended pressure). Check the tire
pressure by looking at the Pressure Gauge (3).
If the tire does not inflate to at least 26 psi (1.8 Bar)
pressure within 15 minutes:
• The tire is too badly damaged. Do not attempt to drive
the vehicle further. Call for assistance.
NOTE: If the tire becomes over-inflated, push the Defla-
tion Button to reduce the tire pressure to the recom-
mended inflation pressure before continuing.
If the tire inflates to the recommended pressure or is at
least 26 psi (1.8 Bar) pressure within 15 minutes:
1. Push the Power Button (4) to turn off the Tire Service Kit.
2. Remove the Speed Limit sticker from the top of the Sealant Bottle (1) and place the sticker on the instru-
ment panel.
540 WHAT TO DO IN EMERGENCIES
(E) After Driving:
Pull over to a safe location. Refer to “Whenever You Stop
to Use Tire Service Kit” before continuing.
1. Push in the Mode Select Knob (5) and turn to the AirMode position.
2. Uncoil the power plug and insert the plug into the vehicle’s 12 Volt power outlet.
3. Uncoil the Air Pump Hose (7) (black in color) and screw the fitting at the end of hose (7) onto the valve
stem.
4. Check the pressure in the tire by reading the Pressure Gauge (3).
If tire pressure is less than 19 psi (1.3 Bar):
The tire is too badly damaged. Do not attempt to drive
the vehicle further. Call for assistance. If the tire pressure is 19 psi (1.3 Bar) or higher:
1. Push the Power Button (4) to turn on Tire Service Kit
and inflate the tire to the pressure indicated on the tire
and loading information label on the driver-side door
opening.
NOTE: If the tire becomes over-inflated, push the Defla-
tion Button to reduce the tire pressure to the recom-
mended inflation pressure before continuing.
2. Disconnect the Tire Service Kit from the valve stem, reinstall the cap on the valve stem and unplug from 12
Volt outlet.
3. Place the Tire Service Kit in its proper storage area in the vehicle.
4. Have the tire inspected and repaired or replaced at the earliest opportunity at an authorized dealer or tire
service center.
