TIRE PRESSURE MONITOR SYSTEM (TPMS) Ð IF
EQUIPPED
The Tire Pressure Monitoring System (TPMS) will warn
the driver of a low tire pressure based on the vehicle
recommended cold tire inflation placard pressure. The
placard pressure is defined on the Tire and Loading
Information label. The Tire and Loading Information
label is located on the drivers side B-pillar. Vehicles
equipped to be operated in either the ªmax load inflation
pressureº condition described on the Tire and Loading
Information label or the alternative ªlight load inflation
pressureº condition described on the Supplemental Tire
Pressure Information label, may also be equipped with a
reset switch to choose the appropriate TPMS low pres-
sure warning threshold levels based upon the vehicle
load condition. The Supplemental Tire Pressure Informa-
tion label is located on the rear face of the driver door.
Operation of the ªLight Loadº reset switch is described
later in this manual section.The tire pressure will vary with temperature by approxi-
mately 1 psi (6.9 kPa) for every 12ÉF (6.5ÉC). 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 a vehicle has not been driven for
more than 3 hours, or driven less than 1 mile (1km/h)
after a 3 hour period.Refer to the ªTires ± General
Informationº in this section 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 pres-
sure.
The TPM System will warn the driver of a low tire
pressure if the tire pressure falls below the low pressure
warning threshold for any reason, including low tem-
perature effects, or natural pressure loss through the tire.

Loadº Reset Switch Description ± If Equipped
WARNING!
Never operate your vehicle with the TPMS and tire
pressures set to the Light Load Inflation Pressure
settings if carrying more than two occupants ( 150 lbs
each) plus 200 pounds of cargo. The vehicle ªLight
Load Definitionº is found in the Supplemental Tire
Pressure Information Label which is located on the
rear face of the driver door. Failure to do so may
cause you to lose control resulting in an accident,
causing serious or fatal injury.The Tire Pressure Monitor (TPM) system ªLight Loadº
reset switch will allow the driver to switch between the
max load inflation pressure (cold) low pressure warning
threshold and the light load inflation pressure (cold) low
pressure warning threshold depending on the vehicle's
load condition. The Tire and Loading Information label
defines the recommended front and rear cold tire infla-
tion pressures for the vehicle when operating in the Max
Load condition. A Supplemental Tire Pressure Informa-
tion label is also available defining Light Load tire
inflation pressures when operating in the Light Load
condition. When the ªLight Loadº reset switch LED is
ON, the Tire Pressure Monitoring (TPM) system is using
the light load inflation pressure (cold) low inflation
warning thresholds and will warn the driver if one or
more of the tire pressures are 25% or more below the
vehicle's defined light load inflation pressures.

Equipped
²
This vehicle may have different recommended tire
pressure values between the front and rear tires as
shown in both the Tire Loading Information Label and
the Supplemental Tire Pressure Information Label
(located on the rear face of the driver door). It is also
equipped to be driven with tire pressures appropriate
to either a Light Load condition or the vehicle Max
Load condition.
²The ªLight Loadº reset switch will allow the driver to
change between the max load inflation pressure (cold)
low pressure warning threshold and the light load
inflation pressure (cold) low pressure warning thresh-
old depending on the vehicle's load condition. Refer to
the ªSupplemental Tire Pressure Informationº label for
the vehicle's Light Load inflation pressures and ªTire
and Loading Information º label for the vehicle's Max
Load inflation pressures.

²The TPMS system will always reset to the max load
inflation pressure (cold) low pressure warning thresh-
old condition when the system experiences a loss of
electrical power. For example, by momentarily discon-
necting the battery or IOD fuse.To switch from the max load inflation pressure (cold) low
pressure warning threshold to the light load inflation
pressure (cold) low pressure warning threshold, the
driver must first lower all four road tire pressures to the
Light Load Inflation Pressure values as listed on the
Supplemental Tire Pressure Information label. The
Supplemental Tire Pressure Information label is located
on the rear face of the driver door. Use an accurate tire
gauge to check the tire pressures when lowering all four
tire pressures. Next proceed to turning the ignition on to
the Run position. This may cause the TPMS low pressure
warning telltale lamp located in the Instrument Cluster to
turn ON and a chime to sound since the tire pressures
have been lowered below the max load inflation pressure
(cold) pressures. After all four tire pressures have been
lowered to the Light Load inflation pressures, press the
ªLight Loadº reset switch. If the ªLight Loadº switch
amber colored LED turns ON, the TPM system low
pressure telltale lamp will illuminate at a tire pressure

25% or more below the light load inflation pressure (cold)
tire pressure values. The light load inflation pressure
(cold) tire pressure values are defined in the Supplemen-
tal Tire Pressure Information label located on the rear face
of the driver door. If the switch LED did not turn ON,
you may need to drive the vehicle for one minute above
15 mph (25 km/h) and then press the ªLight Loadº reset
switch again. Also, the TPM system low pressure telltale
lamp will turn off once the vehicle has been driven for up
to one minute above 15 mph (25 km/h). The TPM system
will now remain in the Light Load vehicle pressure
monitoring condition and the ªLight Loadº reset switch
LED will remain ON for each subsequent key cycle,
unless the system experiences a loss of electrical power as
previously described.If the ªLight Loadº reset switch amber colored LED
flashes on and off for 10 seconds, after all four tire
pressures have been lowered to the Light Load inflation
pressures, the pressure in any one of the four tires may
not be at the light load inflation pressure (cold) values as
indicated for the Light Load condition as defined in the
Supplemental Tire Pressure Information label located on
the rear face of the driver door. Using an accurate tire
pressure gauge, re-check the tire pressures for the light
load inflation pressure (cold) value and drive the vehicle
for up to one minute above 15 mph (25 km/h) and press
the ªLight Loadº reset switch again.

WARNING!
It is the driver 's responsibility to change to the max
load inflation pressure (cold) low pressure warning
threshold condition when not driving in the light
load condition as defined as two occupants ( 150 lbs
each) plus 200 pounds of cargo. The vehicle ªLight
Load Definitionº is found in the Supplemental Tire
Pressure Information Label located on the rear face of
the driver door. Failure to do so may cause you to lose
control resulting in an accident, causing serious or
fatal injury.To switch back to the max load inflation pressure (cold)
low pressure warning threshold, press the ªLight Loadº
reset switch. It is not necessary to first fill the tires to the
max load inflation pressure (cold) values to switch the
TPMS system to the max load inflation pressure (cold)
low pressure warning threshold. If after pressing the
ªLight Loadº reset switch and tire pressures are below
the max load inflation pressure (cold) low pressure
warning thresholds, the TPMS low pressure warning
telltale lamp located in the Instrument Cluster will turn
ON and a chime will sound. The tire pressures are now
required to be inflated to the max load inflation pressure
(cold) values described on the Tire and Loading Informa-
tion label. The Tire and Loading Information label is
located on the drivers side B-pillar. If the ªLight Loadº
reset switch LED turns OFF the TPMS has been reset and
the low pressure telltale lamp will illuminate at tire
pressures 25% or more below the max load inflation
pressure (cold) values.
