The TPMS consists of the following components:
•Receiver module,
• Four TPM sensors,
• Various TPMS messages, which display in the Elec-
tronic Vehicle Information Center (EVIC), and
• TPM Telltale Light
The matching full size spare wheel and tire assembly (if
equipped) has a TPM sensor. The full size spare can be
used in place of any of the four road tires. The TPMS will
only monitor the pressure in the full size spare tire when
it is used in place of a road tire. Otherwise, a spare with
a pressure below the low-pressure limit will not cause the
TPM Telltale Light to illuminate or the chime to sound.Tire Pressure Monitoring Low Pressure Warnings
The TPM Telltale Light will illuminate in the
instrument cluster and a chime will sound when
tire pressure is low in one or more of the four
active road tires. In addition, the EVIC will display a
LOW TIRE message and a graphic showing the pres-
sure values of each tire with the low tire pressure values
flashing or changing color. An Inflate to XXmessage
will also be displayed.
Should this occur, you should stop as soon as possible
and inflate the tires with a low pressure condition (those
flashing or in a different color in the EVIC graphic) to the
vehicle’s recommended cold placard pressure inflation
value as shown in the Inflate to XXmessage. Once the
system receives the updated tire pressures, the system
will automatically update, the graphic display in the
EVIC will stop flashing or change color back to the
original color, and the TPM Telltale Light will turn off.

The EVIC will also display aSERVICE TPM SYSTEM
message for a minimum of five seconds when a system
fault related to an incorrect sensor location fault is
detected. In this case, the SERVICE TPM SYSTEM
message is then followed with a graphic display with
pressure values still shown. This indicates that the pres-
sure values are still being received from the TPM sensors
but they may not be located in the correct vehicle
position. The system still needs to be serviced as long as
the SERVICE TPM SYSTEM message is displayed.
Vehicles With Full Size Spare
1. The matching full size spare wheel and tire assembly has a TPM sensor that can be monitored by the TPMS.
2. If you install the full size spare in place of a road tire that has a pressure below the low-pressure warning
limit, upon the next ignition switch cycle, a chime
will sound and the TPM Telltale Light will turn ON. In addition, the EVIC will display a low pressure
message and a graphic showing the low tire pressure
value flashing or in a different color. An
Inflate to XX
message will also be displayed.
3. After driving the vehicle for up to 20 minutes above 15 mph (24 km/h) the TPM Telltale Light will turn
OFF, and the pressure value displayed will be updated
and stop flashing or return to its original color as long
as no tire pressure is below the low-pressure warning
limit in any of the four active road tires.
Vehicles With Compact Spare
1. The compact spare tire does not have a TPM sensor. Therefore, the TPMS will not monitor the pressure in
the compact spare tire.
474 STARTING AND OPERATING
Page 477 of 631

2. If you install the compact spare tire in place of a roadtire that has a pressure below the low-pressure warn-
ing limit, upon the next ignition switch cycle, the TPM
Telltale Light will remain ON and a chime will sound.
In addition, the graphic in the EVIC will still display a
flashing pressure value or a pressure value in a
different color. An Inflate to XXmessage will also be
displayed.
3. After driving the vehicle for up to 20 minutes above 15 mph (24 km/h), the TPM Telltale Light will flash on
and off for 75 seconds and then remain on solid. In
addition, the EVIC will display a SERVICE TPM
SYSTEM message for a minimum of five seconds and
then display dashes (- -) in place of the pressure value. 4. For each subsequent ignition switch cycle, a chime will
sound, the TPM Telltale Light will flash on and off for
75 seconds and then remain on solid, and the EVIC
will display a SERVICE TPM SYSTEM message for a
minimum of five seconds and then display dashes (- -)
in place of the pressure value.
5. Once you repair or replace the original road tire and reinstall it on the vehicle in place of the compact spare,
the TPMS will update automatically. In addition, the
TPM Telltale Light will turn OFF and the graphic in
the EVIC 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 for the
TPMS to receive this information.

Towing Requirements – Tires
– Do not attempt to tow a trailer while using a compactspare 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 information on tire pressures and 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 informa-
tion on tread wear indicators and for the proper
inspection procedure. – When replacing tires, refer to “Tires – General Infor-
mation” in “Starting and Operating” for information
on replacement tires and for the proper tire replace-
ment 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.

WARNING!
A loose tire or jack thrown forward in a collision or
hard stop could endanger the occupants of the ve-
hicle. Always stow the jack parts and the spare tire in
the places provided. Have the deflated (flat) tire
repaired or replaced immediately.
Preparations For Jacking
1.Park the vehicle on a firm, level surface as far from the
edge of the roadway as possible. Avoid icy or slippery
areas.
WARNING!
Do not attempt to change a tire on the side of the
vehicle close to moving traffic, pull far enough off
the road to avoid being hit when operating the jack
or changing the wheel.2. Turn on the Hazard Warning flasher.
3. Set the parking brake.
4. Place the shift lever into PARK.
5. Turn OFF the ignition.
6. Block the front and rear of thewheel diagonally opposite of the
jacking position. For example, if
changing the right front tire, block
the left rear wheel.
NOTE: Passengers should not remain in the vehicle
when the vehicle is being jacked.

CAUTION!
Do not attempt to raise the vehicle by jacking on
locations other than those indicated in the Jacking
Instructions for this vehicle.1. Remove the spare tire, jack, and lug wrench.
2. If equipped with aluminum wheels where the center
cap covers the lug nuts, use the lug wrench to pry the
center cap off carefully before raising the vehicle.
3. Before raising the vehicle, use the lug wrench to loosen, but not remove, the lug nuts on the wheel with
the flat tire. Turn the lug nuts counterclockwise one
turn while the wheel is still on the ground.
4. Place the jack underneath the lift area that is closest to the flat tire. Turn the jack screw clockwise to firmly
engage the jack saddle with the lift area of the sill
flange.

NOTE:
•For vehicles so equipped, do not attempt to install a
center cap or wheel cover on the compact spare.
•
Refer to “Compact Spare Tire” and to “Limited-Use
Spare” under “Tires—General Information” in “Starting
and Operating” for additional warnings, cautions, and
information about the spare tire, its use, and operation.
8. Install the lug nuts with the cone shaped end of the lug
nut toward the wheel. Lightly tighten the lug nuts.
WARNING!
To avoid the risk of forcing the vehicle off the jack,
do not tighten the lug nuts fully until the vehicle has
been lowered. Failure to follow this warning may
result in personal injury.
9. Lower the vehicle to the ground by turning the jack handle counterclockwise. 10. Finish tightening the lug nuts. Push down on the
wrench while at the end of the handle for increased
leverage. Tighten the lug nuts in a star pattern until
each nut has been tightened twice. The correct tight-
ness of each lug nut is 110 ft/lb. (150 N·m). If in doubt
about the correct tightness, have them checked with
a torque wrench by your authorized dealer or at a
service station.
11. Stow the jack, tools and flat tire. Make sure the base of the jack faces the back of the vehicle before
tightening down the fastener.WARNING!
•A loose tire or jack thrown forward in a collision or
hard stop could endanger the occupants of the vehicle.
• Always stow the jack parts and the spare tire in the
places provided. Have the deflated (flat) tire re-
paired or replaced immediately.
