which display in the Driver Information Display
(DID), and a graphic displaying tire pressures
• Tire Pressure Monitoring Telltale Light
The Tire Pressure Monitoring System (TPMS) will warn
the driver of a low tire pressure based on the vehicle
recommended cold tire placard pressure.
The tire pressure will vary with temperature by about
1 psi (7 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. Refer to “Tires – General Informa-
tion” 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
threshold 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 recommended
cold tire placard pressure. Once the low tire pressure
warning has been illuminated, the tire pressure must be
increased to the recommended cold tire pressure in order
for the Tire Pressure Monitoring Telltale Light to be
turned off.
552 STARTING AND OPERATING
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 system will automatically update and the Tire Pres-
sure Monitoring Telltale Light will extinguish 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.
For example, your vehicle has a recommended cold
(parked for more than three hours) tire placard pressure
of 33 psi (227 kPa). If the ambient temperature is 68°F
(20°C) and the measured tire pressure is 28 psi (193 kPa),
a temperature drop to 20°F (-7°C) will decrease the tire
pressure to approximately 24 psi (165 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 28 psi (193 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 have been inflated to the vehicle’s recommended
cold tire pressure value.
CAUTION!
•
The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures and
warnings have been established for the tire size
equipped on your vehicle. Undesirable system op-
eration 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. After using an after-
market 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 pressure al-
ways reinstall the valve stem cap. This will prevent
moisture and dirt from entering the valve stem,
which could damage the Tire Pressure Monitoring
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.
554 STARTING AND OPERATING
Tire Pressure Monitoring Low Pressure Warnings
The Tire Pressure Monitoring Telltale Light will
illuminate in the instrument cluster, and an au-
dible chime will be activated, when one or more of the
four active road tire pressures are low. In addition, the
DID will display a Tire Lowmessage, an Inflate to
XXX message and a graphic display of the pressure
value(s) with the low tire(s) displayed in a different color.
Refer to “Driver Information Display (DID)” in “Under-
standing Your Instrument Panel” for further information.
NOTE: Your system can be set to display pressure units
in PSI, BAR or kPa. Should a low tire condition occur on any of the four
active road tire(s), you should stop as soon as possible,
and inflate the low tire(s) that is in a different color on the
graphic display to the vehicle’s recommended cold tire
pressure displayed in theInflate to XXXmessage.
Low Tire Pressure Monitor Display
556 STARTING AND OPERATING
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 system will automatically update, the graphic dis-
play of the pressure value(s) will return to its original
color and the Tire Pressure Monitoring Telltale 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 infor-
mation.
Service Tpm System Warning
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. The DID will display a “SERVICE TPM SYS-
TEM” message for a minimum of five seconds. This
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 switch 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 by
any of the following:
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. Lots of 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:There is no tire pressure monitoring sensor in the
spare tire. The TPMS will not be able to monitor the tire
pressure. If you install the spare tire in place of a road tire
that has a pressure below the low-pressure warning limit,
upon the next ignition switch cycle, the Tire Pressure
Monitoring Telltale Light will remain ON, a chime will
sound, and the DID will still display a pressure value in
the different color graphic display and an Inflate to
XXX kPa message will be displayed. After driving the
vehicle for up to 20 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. In addition,
the DID will display a “SERVICE TPM SYSTEM message
for five seconds and then display dashes (- -) in place of the pressure value. For each subsequent ignition switch
cycle, a chime will sound, the Tire Pressure Monitoring
Telltale Light will flash on and off for 75 seconds and then
remain on solid, and the DID will display a
SERVICE
TPM SYSTEM message for five seconds and then dis-
play dashes (- -) in place of the pressure value. Once you
repair or replace the original road tire, and reinstall it on
the vehicle in place of the spare tire, the TPMS will
update automatically.
In addition, the Tire Pressure Monitoring Telltale Light
will turn OFF and the graphic in the DID 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.
558 STARTING AND OPERATING
WARNING!
•Never have any smoking materials lit in or near the
vehicle when the fuel door is open or the tank is
being filled.
• Never add fuel when the engine is running. This is
in violation of most state and federal fire regula-
tions and may cause the “Malfunction Indicator
Light” to turn on.
• A fire may result if fuel is pumped into a portable
container that is inside of a vehicle. You could be
burned. Always place fuel containers on the
ground while filling.
Emergency Fuel Filler Door Release
If you are unable to open the fuel filler door, use the fuel
filler door emergency release.
1. Open the liftgate.
2. Push the inboard edge of the left storage bin to the center, this will pop up the outboard edge.
3. Grab popped up outboard edge with other hand to disengage snaps.
4. Remove the storage bin.
5. Pull the release cable to open the fuel door, push the release cable back to the home position to re-seat the
fuel door latch to the closed position.

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 (453 kg) and required for trailers in excess of
2,000 lbs (907 kg).
WARNING!
• Do not connect trailer brakes to your vehicle’s
hydraulic brake lines. It can overload your brake
system and cause it to fail. You might not have
brakes when you need them and could have a
collision.
• Towing any trailer will increase your stopping
distance. When towing you should allow for addi-
tional space between your vehicle and the vehicle
in front of you. Failure to do so could result in a
collision.
CAUTION!
If the trailer weighs more than 1,000 lbs (453 kg)
loaded, it should have its own brakes and they
should be of adequate capacity. Failure to do this
could lead to accelerated brake lining wear, higher
brake pedal effort, and longer stopping distances.
Towing Requirements — Trailer Lights And Wiring
Whenever you pull a trailer, regardless of the trailer size,
stoplights and turn signals on the trailer are required for
motoring safety.
The Trailer Tow Package may include a four- and seven-
pin wiring harness. Use a factory approved trailer har-
ness and connector.
NOTE: Do not cut or splice wiring into the vehicles
wiring harness.
