— Engine Check/Malfunction Indicator Warning
Light (MIL)
The Engine Check/Malfunction Indicator Light (MIL) is a
part of an Onboard Diagnostic System called OBD II that
monitors engine and automatic transmission control sys-
tems. This warning light will illuminate when the ignition
is in the ON/RUN position before engine start. If the bulb
does not come on when turning the ignition switch from
OFF to ON/RUN, have the condition checked promptly.
Certain conditions, such as a loose or missing gas cap, poor
quality fuel, etc., may illuminate the light after engine start.
The vehicle should be serviced if the light stays on through
several typical driving styles. In most situations, the ve-
hicle will drive normally and will not require towing.
When the engine is running, the MIL may flash to alert
serious conditions that could lead to immediate loss of
power or severe catalytic converter damage. The vehicle
should be serviced by an authorized dealer as soon as
possible if this occurs.4

the 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.

Disabling/Enabling HSA
If you wish to turn the HSA system on or off, it can be done
using the Customer Programmable Features in the
Uconnect Settings. Refer to “Uconnect Settings” in “Multi-
media” for further information.
Electronic Stability Control (ESC)
The Electronic Stability Control (ESC) system enhances
directional control and stability of the vehicle under vari-
ous driving conditions. ESC corrects for oversteering or
understeering of the vehicle by applying the brake of the
appropriate wheel to assist in counteracting the oversteer-
ing or understeering condition. Engine power may also be
reduced to help the vehicle maintain the desired path. ESC
uses sensors in the vehicle to determine the vehicle path
intended by the driver and compares it to the actual path of
the vehicle. When the actual path does not match the
intended path, ESC applies the brake of the appropriatewheel to assist in counteracting the oversteer or understeer
condition.
•
Oversteer - when the vehicle is turning more than
appropriate for the steering wheel position.
• Understeer - when the vehicle is turning less than
appropriate for the steering wheel position.

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, 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 the recommended cold
tire pressure on the placard. Once the low tire pressure
warning (Tire Pressure Monitoring System Warning Light)
illuminates, you must increase the tire pressure to the
recommended cold tire pressure in order for the Tire Pressure
Monitoring System Warning Light to turn off. The system
will automatically update and the Tire Pressure Monitoring
System 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) tire pressure of 30 psi
(207 kPa). If the ambient temperature is 68°F (20°C) and the
measured tire pressure is 27 psi (186 kPa), a temperaturedrop to 20°F (-7°C) will decrease the tire pressure to
approximately 23 psi (159 kPa). This tire pressure is suffi-
ciently low enough to turn on the Tire Pressure Monitoring
System Warning Light. Driving the vehicle may cause the
tire pressure to rise to approximately 27 psi (186 kPa), but
the Tire Pressure Monitoring System Warning Light will
still be on. In this situation, the Tire Pressure Monitoring
System Warning Light will turn off only after the tires are
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 System
Warning Light.
•
Seasonal temperature changes will affect tire pressure, and
the TPMS will monitor the actual tire pressure in the tire.
TPM System With Comfort Cluster
This is the TPMS warning indicator located in the
instrument cluster.
The 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 regularly and to
maintain the proper pressure.
The TPMS consists of the following components:
• Receiver Module
• Four Tire Pressure Monitoring Sensors
• Tire Pressure Monitoring System Warning Light
• Text Message Display
108 SAFETY

Tire Pressure Monitoring Low Pressure Warnings
The Tire Pressure Monitoring System Warning Light will
illuminate in the instrument cluster, an audible chime will
be activated, and the “Low inflation pressure left or right
front/rear tire” text message will display when one or
more of the four active road tire pressures are low. 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 pres-
sure value. The system will automatically update and the
Tire Pressure Monitoring 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.
TPMS Warnings
The Tire Pressure Monitoring System Warning Light will
flash on and off for 75 seconds and remain on solid when
a system fault is detected, an audible chime will be
activated and the “Service Tire Pressure Monitoring Sys-
tem” text message will display. If the ignition key is cycled,
this sequence will repeat providing the system fault still
exists. The Tire Pressure Monitoring System Warning Light
will turn off when the fault condition no longer exists. A
system fault can occur with any of the following scenarios:•
Jamming due to electronic devices or driving next to
facilities emitting the same radio frequencies as the TPM
sensors.
• Installing some form of aftermarket window tinting that
affects radio wave signals.
• Snow or ice around the wheels or wheel housings.
• Using tire chains on the vehicle.
• Using wheels/tires not equipped with TPM sensors.
NOTE: Your vehicle may be equipped with a compact
spare wheel and tire assembly.
• The compact spare tire does not have a tire pressure
monitoring sensor. Therefore, the TPMS will not monitor
the tire pressure in the compact spare tire.
• If you install the compact spare tire in place of a road tire
that has a pressure below the low-pressure warning
limit, upon the next ignition key cycle, a chime will
sound, the Tire Pressure Monitoring System Warning
Light and the Low inflation pressure left or right front /
rear tire message will still turn ON due to the low tire.
• However, after driving the vehicle for up to 20 minutes
above 15 mph (24 km/h), the Tire Pressure Monitoring
System Warning Light will flash on and off for 75

played.
• This occurs for each subsequent ignition key cycle, a
chime will sound and the Tire Pressure Monitoring
System Warning Light will flash on and off for 75
seconds and then remain on solid and the “Service Tire
Pressure Monitoring System” message will be dis-
played.
• Once you repair or replace the original road tire and
reinstall it on the vehicle in place of the compact spare
tire, the TPMS will update automatically and the Tire
Pressure Monitoring System Warning 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 the TPMS
to receive this information.TPM System With (TFT) Tire Pressure Display
Screen
The Tire Pressure Monitor System (TPMS) uses wireless

of the four active road tires. In addition, the instrument
cluster will display a low pressure text message and a
graphic showing the low tire pressure tire highlighted in a
different color.
110 SAFETY

A system fault can occur due to any of the following:
1. Signal interference due to electronic devices or drivingnext to facilities emitting the same radio frequencies as
the TPM sensors.
2. Installing aftermarket window tinting that contains ma- terials that may block radio wave signals.
3. Accumulation 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:
• The TPMS will not monitor the pressure in a replace-
ment tire installed without a tire pressure sensor.
• If you install a replacement 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 System Warning Light will remain
on and a chime will sound. In addition, the graphic in
the instrument cluster will still display a low pressure
message and a tire highlighted in a different color. •
After driving the vehicle for up to 20 minutes above
15 mph (24 km/h), the Tire Pressure Monitoring System
Warning Light will 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 each subsequent ignition switch cycle, a chime will
sound, the Tire Pressure Monitoring System Warning
Light will flash on and off for 75 seconds and then
remain on solid, and the instrument cluster will display
a “Service Tire Pressure Monitoring System” message.
Once you repair or replace the original road tire and
reinstall it, the TPMS will update automatically. In addi-
tion, the Tire Pressure Monitoring System Warning 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 the TPMS to
receive this information.

WARNING!(Continued)
•Never place a rear-facing child restraint in front of an
air bag. A deploying passenger front air bag can
cause death or serious injury to a child 12 years or
younger, including a child in a rear-facing child
restraint.
• Never install a rear-facing child restraint in the front
seat of a vehicle. Only use a rear-facing child re-
straint in the rear seat. If the vehicle does not have a
rear seat, do not transport a rear-facing child restraint
in that vehicle.
Driver And Passenger Front Air Bag Features
The Advanced Front Air Bag system has multistage driver
and front passenger air bags. This system provides output
appropriate to the severity and type of collision as deter-
mined by the Occupant Restraint Controller (ORC), which
may receive information from the front impact sensors (if
equipped) or other system components.
The first stage inflator is triggered immediately during an
impact that requires air bag deployment. A low energy
output is used in less severe collisions. A higher energy
output is used for more severe collisions. This vehicle may be equipped with a driver and/or front
passenger seat belt buckle switch that detects whether the
driver or front passenger seat belt is buckled. The seat belt
buckle switch may adjust the inflation rate of the Ad-
vanced Front Air Bags.
This vehicle may be equipped with driver and/or front
passenger seat track position sensors that may adjust the
inflation rate of the Advanced Front Air Bags based upon
seat position.
WARNING!
•
No objects should be placed over or near the air bag
on the instrument panel or steering wheel because
any such objects could cause harm if the vehicle is in
a collision severe enough to cause the air bag to
inflate.
• Do not put anything on or around the air bag covers
or attempt to open them manually. You may damage
the air bags and you could be injured because the air
bags may no longer be functional. The protective
covers for the air bag cushions are designed to open
only when the air bags are inflating.
