proper 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.
Please note that the TPMS is not a substitute for proper tire
maintenance, and it is the driver’s responsibility to maintain
correct tire pressure, even if under-inflation has not reached
the level to trigger illumination of the TPMS low tire pres-
sure 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 indi -
cator 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, including 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 replace
-
ment or alternate tires and wheels allow the TPMS to
continue to function properly.
Vehicle Security Warning Light
This warning light will illuminate when the vehicle
security alarm system has detected an attempt to
break into the vehicle. CAUTION!
The TPMS has been optimized for the original
equipment 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.
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 aftermarket tire sealant it is
recommended that you take your vehicle to an
authorized dealer to have your sensor function checked.

92 GETTING TO KNOW YOUR INSTRUMENT PANEL
Electronic Stability Control (ESC) Warning Light — If
Equipped
The Electronic Stability Control (ESC) Indicator Light in
the instrument cluster will come on when the ignition is
placed in the ON/RUN or MAR/ON/RUN position, and
when ESC is activated. It should go out with the engine running. If
the “ESC Indicator Light” comes on continuously with the engine
running, a malfunction has been detected in the ESC system. If this
light remains on after several ignition cycles, and the vehicle has
been driven several miles (kilometers) at speeds greater than
30 mph (48 km/h), see your authorized dealer as soon as possible
to have the problem diagnosed and corrected.

• The “ESC OFF Indicator Light” and the “ESC Indicator Light” come on momentarily each time the ignition is
placed in the ON/RUN or MAR/ON/RUN position.

• Each time the ignition is turned to ON/RUN or MAR/ON/ RUN, the ESC system will be on, even if it was turned off
previously.

• The ESC system will make buzzing or clicking sounds when it is active. This is normal; the sounds will stop when
ESC becomes inactive.
• This light will come on when the vehicle is in an ESC event. Electronic Stability Control (ESC) OFF Warning Light —
If Equipped
This warning light indicates the Electronic Stability
Control (ESC) is off.

Each time the ignition is turned to ON/RUN or ACC/ON/RUN,
the ESC system will be on, even if it was turned off previously.

Green Indicator Lights
Turn Signal Indicator Lights When the left or right turn signal is activated, the
turn signal indicator will flash independently and
the corresponding exterior turn signal lamps will
flash. Turn signals can be activated when the multifunction
lever is moved down (left) or up (right).
NOTE:
• A continuous chime will sound if the vehicle is driven more than 1 mile (1.6 km) with either turn signal on.
• Check for an inoperative outside light bulb if either indicator flashes at a rapid rate.

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 127
and seated properly, or if items are positioned in the area
where the SABICs inflate. Children are at an even greater
risk of injury from a deploying air bag.
The SABICs may help reduce the risk of partial or complete
ejection of vehicle occupants through side windows in
certain side impact events.Side Impacts
The Side Air Bags are designed to activate in certain side
impacts. The Occupant Restraint Controller (ORC) deter
-
mines whether the deployment of the Side Air Bags in a
particular impact event is appropriate, based on the severity
and type of collision. The side impact sensors aid the ORC in
determining the appropriate response to impact events. The
system is calibrated to deploy the Side Air Bags on the
impact side of the vehicle during impacts that require Side
Air Bag occupant protection. In side impacts, the Side Air
Bags deploy independently; a left side impact deploys the
left Side Air Bags only and a right-side impact deploys the
right Side Air Bags only. Vehicle damage by itself is not a
good indicator of whether or not Side Air Bags should have
deployed.
The Side Air Bags will not deploy in all side collisions,
including some collisions at certain angles, or some side
collisions that do not impact the area of the passenger
compartment. The Side Air Bags may deploy during angled
or offset frontal collisions where the front air bags deploy.
Side Air Bags are a supplement to the seat belt restraint
system. Side Air Bags deploy in less time than it takes to
blink your eyes.
WARNING!
• Do not mount equipment, or stack luggage or other cargo up high enough to block the deployment of the
SABICs. The trim covering above the side windows
where the SABIC and its deployment path are located
should remain free from any obstructions.
• In order for the SABICs to work as intended, do not install any accessory items in your vehicle which could
alter the roof. Do not add an aftermarket sunroof to
your vehicle. Do not add roof racks that require perma -
nent attachments (bolts or screws) for installation on
the vehicle roof. Do not drill into the roof of the vehicle
for any reason.

Enhanced Accident Response System
In the event of an impact, if the communication network
remains intact, and the power remains intact, depending on
the nature of the event, the ORC will determine whether to
have the Enhanced Accident Response System perform the
following functions:
• Cut off fuel to the engine (if equipped)
• Cut off battery power to the electric motor (if equipped)
• Flash hazard lights as long as the battery has power
• Turn on the interior lights, which remain on as long as thebattery has power or for 15 minutes from the intervention
of the Enhanced Accident Response System
• Unlock the power door locks
Your vehicle may also be designed to perform any of these
other functions in response to the Enhanced Accident
Response System:
• Turn off the Fuel Filter Heater, Turn off the HVAC Blower Motor, Close the HVAC Circulation Door • Cut off battery power to the:
• Engine
• Electric Motor (if equipped)
• Electric Power Steering
• Brake booster
• Automatic transmission gear selector

• Front wiper
NOTE:
After an accident, remember to cycle the ignition to the STOP
(OFF/LOCK) position and remove the key from the ignition
switch to avoid draining the battery. Carefully check the
vehicle for fuel leaks in the engine compartment and on the
ground near the engine compartment and fuel tank before
resetting the system and starting the engine. If there are no
fuel leaks or damage to the vehicle electrical devices (e.g.
headlights) after an accident, reset the system by following
the procedure described below. If you have any doubt,
contact an authorized dealer.
