Light — If Equipped
This warning light will illuminate to indicate a fault in the
Forward Collision Warning System. Contact an authorized
dealer for service.
Refer to Forward Collision Warning (FCW) inSafety for
further information.
— Service Stop/Start System Warning Light — If
Equipped
This warning light will illuminate when the Stop/Start
system is not functioning properly and service is required.
Contact an authorized dealer for service.
— Tire Pressure Monitoring System (TPMS)
Warning Light
The warning light switches on and a message is displayed
to indicate that the tire pressure is lower than the recom-
mended value and/or that slow pressure loss is occurring.
In these cases, optimal tire duration and fuel consumption
may not be guaranteed. Should one or more tires be in the condition mentioned
above, the display will show the indications corresponding
to each tire.
CAUTION!
Do not continue driving with one or more flat tires as
handling may be compromised. Stop the vehicle,
avoiding sharp braking and steering. If a tire puncture
occurs, repair immediately using the dedicated tire
repair kit and contact an authorized dealer as soon as
possible.
Each tire, including the spare (if provided), should be
checked monthly when cold and inflated to the inflation
pressure recommended by the vehicle manufacturer on the
vehicle placard or tire inflation pressure label. (If your
vehicle has tires of a different size than the size indicated
on the vehicle placard or tire inflation pressure label, you
should determine the proper tire inflation pressure for
those tires.)
As an added safety feature, your vehicle has been
equipped with a Tire Pressure Monitoring System (TPMS)
that illuminates a low tire pressure telltale when one or
212 GETTING TO KNOW YOUR INSTRUMENT PANEL

more of your tires is significantly under-inflated. Accord-
ingly, when the low tire pressure telltale illuminates, you
should stop and check your tires as soon as possible, and
inflate them to the proper pressure. Driving on a signifi-
cantly 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.
Please note that the TPMS is not a substitute for proper tire
maintenance, and it is the driver ’s responsibility to main-
tain correct tire pressure, even if under-inflation has not
reached the level to trigger illumination of the TPMS low
tire pressure telltale.
Your vehicle has also been equipped with a TPMS malfunc-
tion indicator to indicate when the system is not operating
properly. The TPMS malfunction indicator is combined
with the low tire pressure telltale. When the system detects
a malfunction, the telltale will flash for approximately one
minute and then remain continuously illuminated. This
sequence will continue upon subsequent vehicle start-ups
as long as the malfunction exists. When the malfunction
indicator is illuminated, the system may not be able to
detect or signal low tire pressure as intended. TPMS
malfunctions may occur for a variety of reasons, includingthe installation of replacement or alternate tires or wheels
on the vehicle that prevent the TPMS from functioning
properly. Always check the TPMS malfunction telltale after
replacing one or more tires or wheels on your vehicle to
ensure that the replacement or alternate tires and wheels
allow the TPMS to continue to function properly.
CAUTION!
The TPMS has been optimized for the original equip-
ment tires and wheels. TPMS pressures and warning
have been established for the tire size equipped on
your vehicle. Undesirable system operation or sensor
damage may result when using replacement equip-
ment 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 inoper-
able. After using an aftermarket tire sealant it is
recommended that you take your vehicle to your au-
thorized dealer to have your sensor function checked.

GETTING TO KNOW YOUR INSTRUMENT PANEL 213

Tire Pressure Monitor System (TPMS)
The Tire Pressure Monitor System (TPMS) will warn the
driver of a low tire pressure based on the vehicle recom-
mended cold placard pressure.
NOTE:The TPMS Warning 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 instrument cluster will display a graphic
showing the pressure values of each tire with the low tire
pressure values in a different color, or the Uconnect radio
will display a TPMS message, when this occurs you must
increase the tire pressure to the recommended cold placard
pressure in order for the TPMS Warning Light to turn off.
The tire pressure will vary with temperature by approxi-
mately 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. The cold tire inflation pressure must not
exceed the maximum inflation pressure molded into the
tire sidewall. Refer to “Tires” in “Servicing and Mainte-
nance” 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 and 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 warning
(TPMS Warning Light) illuminates, you must increase the
tire pressure to the recommended cold placard pressure in
order for the TPMS Warning Light to turn off.
The system will automatically update and the TPMS
Warning Light will turn off once the system receives the
updated tire pressures. 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.
For example, your vehicle may have a recommended cold
(parked for more than three hours) 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

SAFETY 241

•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 pressure
gauge, even if underinflation has not reached the level to
trigger illumination of the TPMS Warning Light.
•
Seasonal temperature changes will affect tire pressure, and
the TPMS will monitor the actual tire pressure in the tire.
Premium System
The Tire Pressure Monitor System (TPMS) uses wireless
technology with wheel rim mounted electronic sensors to
monitor tire pressure levels. Sensors, mounted to each
wheel as part of the valve stem, transmit tire pressure
readings to the receiver module.
NOTE: It is particularly important for you to check the tire
pressure 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 sensors
• Various tire pressure monitoring system messages,
which display in the instrument cluster
• Tire Pressure Monitoring System Warning Light
Tire Pressure Monitoring Low Pressure Warnings
The TPMS Warning 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 instrument cluster will display an Inflate
to XX message and a graphic showing the pressure values
of each tire with the low tire pressure values in a different
color.
Should this occur, you should stop as soon as possible and
inflate the tires with low pressure (those in a different color

SAFETY 243

Periodic Safety Checks You Should Make Outside
The Vehicle
Tires
Examine tires for excessive tread wear and uneven wear
patterns. Check for stones, nails, glass, or other objects
lodged in the tread or sidewall. Inspect the tread for cuts
and cracks. Inspect sidewalls for cuts, cracks, and bulges.
Check the wheel nuts for tightness. Check the tires (includ-
ing spare) for proper cold inflation pressure.
Lights
Have someone observe the operation of brake lights and
exterior lights while you work the controls. Check turn
signal and high beam indicator lights on the instrument
panel.
Door Latches
Check for proper closing, latching, and locking.
Fluid Leaks
Check area under the vehicle after overnight parking for
fuel, coolant, oil, or other fluid leaks. Also, if gasoline
fumes are detected or if fuel, or brake fluid leaks are
suspected. The cause should be located and corrected
immediately.

SAFETY 315

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.
Loading
The actual total weight and the weight of the front and rear
of your vehicle at the ground can best be determined by
weighing it when it is loaded and ready for operation.
The entire vehicle should first be weighed on a commercial
scale to insure that the GVWR has not been exceeded. The
weight on the front and rear of the vehicle should then bedetermined separately to be sure that the load is properly
distributed over the front and rear axle. Weighing the
vehicle may show that the GAWR of either the front or rear
axles has been exceeded but the total load is within the
specified GVWR. If so, weight must be shifted from front to
rear or rear to front as appropriate until the specified
weight limitations are met. Store the heavier items down
low and be sure that the weight is distributed equally. Stow
all loose items securely before driving.
Improper weight distributions can have an adverse effect
on the way your vehicle steers and handles and the way
the brakes operate.
CAUTION!
Do not load your vehicle any heavier than the GVWR
or the maximum front and rear GAWR. If you do, parts
on your vehicle can break, or it can change the way
your vehicle handles. This could cause you to lose
control. Also overloading can shorten the life of your
vehicle.

STARTING AND OPERATING 425

•Proper tire inflation pressures are essential to the safe
and satisfactory operation of your vehicle. Refer to
“Tires” in “Servicing And Maintenance” 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” in “Servicing And
Maintenance” for the proper inspection procedure.
•
When replacing tires, refer to “Tires” in “Servicing And
Maintenance” for the 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 per-
sonal injury.
• An electronically actuated trailer brake controller is
required when towing a trailer with electronically actu-
ated 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 hy-
draulic brake lines. It can overload your brake sys-
tem and cause it to fail. You might not have brakes
when you need them and could have an accident.
• Towing any trailer will increase your stopping dis-
tance. When towing, you should allow for additional
space between your vehicle and the vehicle in front
of you. Failure to do so could result in an accident.
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.
434 STARTING AND OPERATING

CAUTION!
Be sure to mount the inflatable spare tire with the
valve stem facing outward. The vehicle could be dam-
aged if the inflatable spare tire is mounted incorrectly.
NOTE: Do not install the wheel cover on the inflatable
spare tire.
7. Leave the vehicle on the jack and start inflating the inflatable spare after the tire has been mounted to the
vehicle. Secure the wheel to the hub by tightening the nuts with wrench. After inflation, once the vehicle is
lowered you will have a second opportunity to “torque”
the lug nuts.
8. Inflate the tire to the prescribed pressure 60 psi (4.2 Bar) using the Portable Air Compressor or Tire Service Kit if
equipped. Refer to “Portable Air Compressor” in this
section for usage procedure if equipped. Refer to “Tire
Service Kit For Inflating Tire” in this section for usage
procedure if equipped.
9. Lower the vehicle once the inflatable Spare has reached its pressure and the compressor-hose has been removed
from the tire valve.
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. Refer to “Torque
Specifications” in “Technical Specifications” for proper
wheel lug nut torque. If in doubt about the correct
tightness, have them checked with a torque wrench by
your authorized dealer or at a service station.

NOTE:Sealant may leak out through the puncture in the
tire.
If the sealant (white fluid) does not flow within0–10
seconds through the Sealant Hose:
1. Push the Power Button to turn the Tire Service Kit off. Disconnect the Sealant Hose from the valve stem. Make
sure the valve stem is free of debris. Reconnect the
Sealant Hose to the valve stem. Check that the Mode
Select Knob is in the Sealant Mode position and not Air
Mode. Push the Power Button to turn the Tire Service
Kit on.
2. Connect the Power Plug to a different 12 Volt power outlet in your vehicle or another vehicle, if available.
Make sure the vehicle is running before turning the Tire
Service Kit on.
3. The Sealant Bottle may be empty due to previous use. Call for assistance. If the sealant (white fluid) does flow through the Sealant
Hose:
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, the Pres-
sure Gauge can read as high as 70 psi
(4.8 Bar). The Pressure Gauge will
decrease quickly from approximately
70 psi (4.8 Bar) to the actual tire
pressure when the Sealant Bottle is empty.
2. The pump will start to inject air into the tire immedi- ately after the Sealant Bottle is empty.
Continue to operate the pump and
inflate the tire to the cold tire inflation
pressure found on the tire and load-
ing information label located in the
driver-side door opening. Check the
tire pressure by looking at the Pres-
sure Gauge.

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.
If the tire inflates to the recommended pressure or is at
least 26 psi (1.8 Bar) pressure within 15 minutes:
NOTE: If the tire becomes over-inflated, push the Deflation
Button to reduce the tire pressure to the recommended
inflation pressure before continuing.
1. Push the Power Button to turn theTire Service Kit off.
2. Remove the speed limit label from the Tire Service Kit and place sticker on the steering
wheel. 3. Immediately disconnect the Sealant Hose from the valve
stem, reinstall the cap on the fitting at the end of the
hose, and place the Tire Service Kit in the vehicle storage
location. Proceed to “Drive Vehicle.”
Drive Vehicle:
Immediately after injecting sealant and inflating the tire, drive the vehicle 5 miles (8 km) or 10
minutes to ensure distribution of the
Tire Service Kit Sealant within the tire.
Do not exceed 50 mph (80 km/h).
WARNING!
The Tire Service Kit is not a permanent flat tire repair.
Have the tire inspected and repaired or replaced after
using the Tire Service Kit. Do not exceed 50 mph
(80 km/h) until the tire is repaired or replaced. Failure
to follow this warning can result in injuries that are
serious or fatal to you, your passengers, and others
around you. Have the tire checked as soon as possible
at your authorized dealer.
