SAFETY 237
NOTE:
It is particularly important for you to check the tire
press u
re in all of the tires on your vehicle monthly
and to maintain the proper pressure.
The TPMS consists of the following components:
Receiver module
Four Tire Pressure Monitoring System sensors
Tire Pressure Monitoring System Light
TIRE PRESSURE MONITORING SYSTEM LOW
PRESSURE WARNINGS
The Tire Pressure Monitoring System
Light will illuminate in the instrument
clust e
r, a “LOW TIRE PRESSURE”
message will display in the instrument
cluster, an "Inflate to XX" message will be displayed
and a chime will sound when tire pressure is low in
one or more of the four active road tires. 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 as
shown in the "Inflate to XX" message. Once the
system receives the updated tire pressures, the
system will automatically update and the Tire
Pressure Monitoring System Light will turn off.
NOTE:
When filling warm tires, the tire pressure may need
to be i
ncreased up to an additional 4 psi (28 kPa)
above the recommended cold placard pressure in
order to turn the Tire Pressure Monitoring System
Light off. The vehicle may need to be driven for up
to 20 minutes above 15 mph (24 km/h) in order
for th e
TPMS to receive this information.
SERVICE TPMS WARNING
When a system fault is detected, the Tire Pressure
Monitoring System Light will flash on and off for
75 seconds and then remain on solid. The system
fault
will also sound a chime. If the ignition is
cycled, this sequence will repeat, providing the
system fault still exists. The Tire Pressure
Monitoring System Light will turn off when the fault
condition no longer exists. A system fault can occur
due to any of the following:
Jamming due to electronic devices or driving
next to facilities emitting the same radio
frequencies as the TPMS sensors.
Installing some form of aftermarket window
tinting that affects radio wave signals.
Lots of snow or ice around the wheels or wheel
housings.
Using tire chains on the vehicle.
Using wheels/tires not equipped with TPMS
sensors. Vehicles With Compact Spare Or Non-Matching
Full
S
ize Spare
1. The compact spare tire or non-matching full size
spare tire does not have a Tire Pressure
Monitoring System sensor. Therefore, the
TPMS will not monitor the pressure in the
spare tire.
2. If you install the compact or non-matching full size
spare tire in place of a road tire that has a
pressure below the low-pressure warning limit, a
chime will sound and the TPMS Light and “LOW
TIRE PRESSURE” and "Inflate to XX" messages
will turn on upon the next ignition cycle.
3. After driving the vehicle for up to 20 minu
tes
above 1
5 mph (24 km/h), the TPMS Light will
flash
on and off for 75 seconds and then
remain on solid.
4. For each subsequent ignition cycle, a chime will
sound and the TPMS 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 r
einstall it on the vehicle in place of the
compact spare or non-matching full size spare,
the TPMS will update automatically and the
“TPMS 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 th e
TPMS to receive this information.

Full
S
ize Spare
1. The compact spare tire or non-matching full size
does not have a Tire Pressure Monitoring
System sensor. Therefore, the TPMS will not
monitor the pressure in the compact spare
tire.
2. If you install the compact or non-matching full size
spare tire in place of a road tire that has a
pressure below the low-pressure warning limit,
upon the next ignition key cycle, the TPMS
Light will remain on and a chime will sound. In
addition, the graphic in the instrument cluster
will still display a different color pressure value
and an "Inflate to XX" message.
3. After driving the vehicle for up to 20 minu
tes
above 1

flash
on and off for 75 seconds and then
remain on solid. In addition, the instrument
cluster will display a “SERVICE TPM SYSTEM”
message for five seconds and then display
dashes (--) in place of the pressure value.
4. For each subsequent ignition key cycle, a chime
will sound, the TPMS Light will flash on
and off for 75 seconds and then remain on
solid, and the instrument cluster will display a
“SERVICE TPM SYSTEM” message for five
seconds and then display dashes (--) in place
of the pressure value. 5. Once you repair or replace the original road tire
and r
einstall it on the vehicle in place of the
compact spare or non-matching full size, the
TPMS will update automatically. In addition,
the TPMS Light will turn off and the graphic in
the instrument cluster will display a new
pressure value instead of dashes (--), 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 f
or the TPMS to receive this information.
TPMS Deactivation — If Equipped
The TPMS can be deactivated if replacing all four
wheel and tire assemblies (road tires) with wheel
and tire assemblies that do not have TPMS
sensors, such as when installing Winter wheel and
tire assemblies on your vehicle. To deactivate the
TPMS, first, replace all four wheel and tire
assemblies (road tires) with tires not equipped with
Tire Pressure Monitoring System sensors. Then,
drive the vehicle for 20 minutes above 15 mph
(24 km /
h). The TPMS will chime, the TPMS Light

NOTE:
Under a maximum loaded vehicle condition, Gross
Axle W
eight Rating (GAWR) for the front and rear
axles must not be exceeded.

SERVICING AND MAINTENANCE 327
To determine the maximum loading conditions of
your vehicle, locate the statement “The combined
weight of occupants and cargo should never
exceed XXX kg or XXX lbs” on the Tire and Loading
Information placard. The combined weight of
occupants, cargo/luggage and trailer tongue
weight (if applicable) should never exceed the
weight referenced here.
Steps For Determining Correct Load
Limit—
(1) Locate the statement “The combined
weight
of occupants and cargo should
never exceed XXX kg or XXX lbs.” on your
vehicle's placard.
(2) Determine the combined weight of
the dri
ver and passengers that will be
riding in your vehicle.
(3) Subtract the combined weight of the
driver
and passengers from XXX kg or
XXX lbs. (4) The resulting figure equals the
avail
a
ble amount of cargo and luggage
load capacity. For example, if “XXX”
amount equals 1400 lbs. and there will
be five 150 lb passengers in your
vehicle, the amount of available cargo
and luggage load capacity is 650 lbs.
(1400-750 (5x150) = 650 lbs.)
(5) Determine the combined weight of
luggag
e and cargo being loaded on the
vehicle. That weight may not safely
exceed the available cargo and luggage
load capacity calculated in Step 4.
(6) If your vehicle will be towing a trailer,
load fr
om your trailer will be transferred
to your vehicle. Consult this manual to
determine how this reduces the
available cargo and luggage load
capacity of your vehicle.
Metric Example For Load Limit
For example, if “XXX” amount equals 635 kg and
there
will be five 68 kg passengers in your vehicle,
the amount of available cargo and luggage load
capacity is 295 kg (635-340 (5x68) = 295 kg) as
shown in step 4.
NOTE:
If your vehicle will be towing a trailer, load from
your trailer will be transferred to your vehicle.
The following table shows examples on how to
calculate total load, cargo/luggage, and towing
capacities of your vehicle with varying seating
configurations and number and size of occu -
pants. This table is for illustration purposes only
a nd m a
y not be accurate for the seating and
load carry capacity of your vehicle.
For the following example, the combined weight
of occupants and cargo should never exceed
865 lbs (392 kg).
