SAFETY 101
Electronic Roll Mitigation (ERM)
Electronic Roll Mitigation (ERM) anticipates the potential for
wheel lift by monitoring the driver’s steering wheel input
and the speed of the vehicle. When ERM determines that the
rate of change of the steering wheel angle and vehicle’s
speed are sufficient to potentially cause wheel lift, it then
applies the appropriate brake and may also reduce engine
power to lessen the chance that wheel lift will occur.
ERM can only reduce the chance of wheel lift occurring
during severe or evasive driving maneuvers; it cannot
prevent wheel lift due to other factors, such as road
conditions, leaving the roadway, or striking objects or other
vehicles.Hill Start Assist (HSA)
Hill Start Assist (HSA) is designed to assist the driver when
starting a vehicle from a stop on a hill. HSA will maintain the
level of brake pressure the driver applied for a short period
of time after the driver takes their foot off of the brake pedal.
If the driver does not apply the throttle during this short
period of time, the system will release brake pressure and the
vehicle will roll down the hill. The system will release brake
pressure in proportion to the amount of throttle applied as
the vehicle starts to move in the intended direction of travel.
HSA Activation Criteria
The following criteria must be met in order for HSA to
activate:
• The vehicle must be stopped.
• The vehicle must be on a 5% (approximate) grade or
greater hill.
• Gear selection matches vehicle uphill direction (i.e., vehicle facing uphill is in forward gear; vehicle backing
uphill is in REVERSE (R) gear).

HSA will work in REVERSE and all forward gears when the
activation criteria have been met. The system will not activate if
the vehicle is placed in NEUTRAL (N) or PARK (P).

WARNING!
Many factors, such as vehicle loading, road conditions
and driving conditions, influence the chance that wheel
lift or rollover may occur. ERM cannot prevent all wheel
lift or roll overs, especially those that involve leaving the
roadway or striking objects or other vehicles. The
capabilities of an ERM-equipped vehicle must never be
exploited in a reckless or dangerous manner which could
jeopardize the user's safety or the safety of others.

102 SAFETY
Traction Control System (TCS)
The Traction Control System (TCS) monitors the amount of
wheel spin of each of the driven wheels. If wheel spin is
detected, brake pressure is applied to the slipping wheel(s)
and engine power is reduced to provide enhanced accelera-
tion and stability. A feature of the TCS system, Brake Limited
Differential (BLD), functions similar to a limited slip differ -
ential and controls the wheel spin across a driven axle. If one
wheel on a driven axle is spinning faster than the other, the
system will apply the brake of the spinning wheel. This will
allow more engine torque to be applied to the wheel that is
not spinning. This feature remains active even if TCS and
ESC are in the Partial Off mode. Refer to “Electronic Stability
Control (ESC)” in this section for further information. Trailer Sway Control (TSC) — If Equipped
Trailer Sway Control (TSC) uses sensors in the vehicle to
recognize an excessively swaying trailer and will take the
appropriate actions to attempt to stop the sway. The system
may reduce engine power and apply the brake of the appro
-
priate wheel(s) to counteract the sway of the trailer. TSC will
become active automatically once an excessively swaying
trailer is recognized.
NOTE:
TSC cannot stop all trailers from swaying. Always use
caution when towing a trailer and follow the trailer tongue
weight recommendations. Refer to “Trailer Towing” in
“Starting And Operating” for further information.
When TSC is functioning, the “ESC Activation/Malfunction
Indicator Light” will flash, the engine power may be reduced
and you may feel the brakes being applied to individual
wheels to attempt to stop the trailer from swaying. TSC is
disabled when the ESC system is in the “Partial Off” mode.
WARNING!
There may be situations on minor hills with a loaded
vehicle, or while pulling a trailer, when the system will
not activate and slight rolling may occur. This could
cause a collision with another vehicle or object. Always
remember the driver is responsible for braking the
vehicle.
WARNING!
If TSC activates while driving, slow the vehicle down,
stop at the nearest safe location, and adjust the trailer
load to eliminate trailer sway.

104 SAFETY
27 psi (186 kPa), but the TPMS Warning Light will still be on.
In this situation, the TPMS Warning Light will turn off only
after the tires are inflated to the vehicle’s recommended cold
placard pressure value.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 maintenance, and it is the driver’s responsibility to maintain correct tire
pressure using an accurate tire pressure gauge, even if
under-inflation has not reached the level to trigger illumi -
nation of the TPMS Warning Light.
• Seasonal temperature changes will affect tire pressure, and the TPMS will monitor the actual tire pressure in the tire.
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 equipment
that is not of the same size, type, and/or style. After -
market wheels can cause sensor damage.
• Using aftermarket tire sealants may cause the Tire Pres -
sure Monitoring System (TPMS) sensor to become
inoperable. After using an aftermarket tire sealant it is
recommended that you take your vehicle to an autho -
rized dealership to have your sensor function checked.
• After inspecting or adjusting the tire pressure always reinstall the valve stem cap. This will prevent moisture
and dirt from entering the valve stem, which could
damage the TPMS sensor.

SAFETY 105
Base SystemThis 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
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 “Check tire pressure” text message will
display when one or more of the four active road tire pres -
sures 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 pressure value. The system will automatically
update and the Tire Pressure Monitoring Light will extin
-
guish 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.
Check TPMS Warnings
The Tire Pressure Monitoring 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 a
proper text message will be displayed. If the ignition key is
cycled, this sequence will repeat providing the system fault
still exists. The Tire Pressure Monitoring Warning Light will
turn off when the fault condition no longer exists. A system
fault can occur with any of the following scenarios:
1. Jamming due to electronic devices or driving next to facil -
ities emitting the same radio frequencies as the TPM
sensors.
2. Installing some form of aftermarket window tinting that affects radio wave signals.
3. Snow or ice around the wheels or wheel housings.

106 SAFETY
4. Using tire chains on the vehicle.
5. Using wheels/tires not equipped with TPM sensors.
NOTE:
Your vehicle can be equipped with either Tire Service Kit,
compact spare tire or regular size spare tire (with or without
original TPMS sensor).
1. Tire Service Kit (original tire sealant – if equipped): Afterfixing the punctured tire with original tire sealant, the
original situation will be restored, so system will turn off
the telltale during the normal drive.
2. Compact Spare Tire – (if equipped): The compact spare wheel is not equipped with TPMS sensor. So when
mounted, during the normal drive the system will turn
on the telltale (flashing for approximately 75 seconds then
remains solid). This condition persists until a wheel
equipped with original TPMS sensor has been mounted
on the vehicle. 3. Regular size spare tire (not equipped with TPMS sensor):
When mounted, during the normal drive the system will
turn on the telltale (flashing for approximately 75 seconds
then remains solid). This condition persists until a wheel
equipped with original TPMS sensor has been mounted
on the vehicle. Then the system will be restored and the
telltale will turn off during the normal drive.
4. Regular size spare tire (equipped with TPMS sensor): When mounted, the telltale will turn off during the
normal drive.
5. In all the above cases please check the replacement tire inflation pressure before driving your vehicle.
6. In case of tire replacement, if the vehicle is driven for short periods of time, then the system can take a while to
be restored.
NOTE:
For a correct Tire Pressure Monitoring behavior, please wait
for about 20 minutes in key-off during each tire substitution.

SAFETY 123
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 Advanced
Front Air Bags.
• 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 restraint
in the rear seat. If the vehicle does not have a rear seat,
do not transport a rear-facing child restraint in that
vehicle.
WARNING! (Continued)
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 colli -
sion 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.
• Relying on the air bags alone could lead to more severe injuries in a collision. The air bags work with your seat
belt to restrain you properly. In some collisions, air
bags won’t deploy at all. Always wear your seat belts
even though you have air bags.
