WARNING!
During power operation, personal injury or cargo
damage may occur. Ensure the liftgate travel path is
clear. Make sure the liftgate is closed and latched
before driving away.
NOTE:
• The power liftgate buttons will not operate if the vehicle
is in gear or the vehicle speed is above 0 MPH (0 km/h).
•
The power liftgate will not operate in temperatures below
22°F (30°C) or temperatures above 150° F (65° C). Be
sure to remove any buildup of snow or ice from the
liftgate before pushing any of the power liftgate switches.
• If anything obstructs the power liftgate while it is
closing or opening, the liftgate will automatically re-
verse to the closed or open position, provided it meets
sufficient resistance.
• There are also pinch sensors attached to the side of the
liftgate. Light pressure anywhere along these strips will
cause the liftgate to return to the open position.
• If the liftgate is not fully open, push the liftgate button
on the key fob twice to operate the liftgate. •
If the electronic liftgate release is pushed while the
power liftgate is closing, the liftgate will reverse to the
full open position.

power liftgate is opening, the liftgate motor will disen-
gage to allow manual operation.
• If the power liftgate encounters multiple obstructions
within the same cycle, the system will automatically
stop and the liftgate must be opened or closed manually.
WARNING!
• Driving with the liftgate open can allow poisonous
exhaust gases into your vehicle. You and your pas-
sengers could be injured by these fumes. Keep the
liftgate closed when you are operating the vehicle.
• If you are required to drive with the liftgate open,
make sure that all windows are closed, and the
climate control blower switch is set at high speed. Do
not use the recirculation mode.
106 GETTING TO KNOW YOUR VEHICLE

Battery Saver On/Battery Saver Mode Message —
Electrical Load Reduction Actions — If Equipped
This vehicle is equipped with an Intelligent Battery Sensor
(IBS) to perform additional monitoring of the electrical
system and status of the vehicle battery.
In cases when the IBS detects charging system failure, or
the vehicle battery conditions are deteriorating, electrical
load reduction actions will take place to extend the driving
time and distance of the vehicle. This is done by reducing
power to or turning off non-essential electrical loads.
Load reduction is only active when the engine is running.
It will display a message if there is a risk of battery
depletion to the point where the vehicle may stall due to
lack of electrical supply, or will not restart after the current
drive cycle.
When load reduction is activated, the message “Battery
Saver On” or “Battery Saver Mode” will appear in the
instrument cluster display.
These messages indicate the vehicle battery has a low state
of charge and continues to lose electrical charge at a rate
that the charging system cannot sustain.NOTE:
•
The charging system is independent from load reduc-
tion. The charging system performs a diagnostic on the
charging system continuously.
• If the Battery Charge Warning Light is on it may indicate
a problem with the charging system. Refer to “Battery
Charge Warning Light” in ”Warning And Indicator
Lights And Messages” located in ”Getting To Know
Your Instrument Panel” for further information.
The electrical loads that may be switched off (if equipped),
and vehicle functions which can be effected by load
reduction:
• Heated Seat/Vented Seats/Heated Wheel
• Heated/Cooled Cup Holders — If Equipped
• Rear Defroster And Heated Mirrors
• HVAC System
• 115V AC Power Inverter System
• Audio and Telematics System
140 GETTING TO KNOW YOUR INSTRUMENT PANEL

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, 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 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 an autho-
rized dealer to have your sensor function checked.
154 GETTING TO KNOW YOUR INSTRUMENT PANEL

Traction Control System (TCS)
This system monitors the amount of wheel spin of each of
the driven wheels. If wheel spin is detected, the TCS may
apply brake pressure to the spinning wheel(s) and/or
reduce engine power to provide enhanced acceleration and
stability. A feature of the TCS, Brake Limited Differential
(BLD), functions similar to a limited slip differential 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. BLD may remain enabled even if TCS
and ESC are in a reduced mode.
Electronic Stability Control (ESC)
This system enhances directional control and stability of
the vehicle under various driving conditions. ESC corrects
for oversteering or understeering of the vehicle by apply-
ing the brake of the appropriate wheel(s) to assist in
counteracting the oversteer or understeer condition. En-
gine 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 appropriate
wheel 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.
The “ESC Activation/Malfunction Indicator Light” located
in the instrument cluster will start to flash as soon as the ESC
system becomes active. The “ESC Activation/Malfunction
Indicator Light” also flashes when the TCS is active. If the
“ESC Activation/Malfunction Indicator Light” begins to
flash during acceleration, ease up on the accelerator and
apply as little throttle as possible. Be sure to adapt your
speed and driving to the prevailing road conditions.

SAFETY 173

Trailer Sway Control (TSC)
TSC uses sensors in the vehicle to recognize an excessively
swaying trailer and will take the appropriate actions to
attempt to stop the sway. TSC will become active automati-
cally once an excessively swaying trailer is recognized.
Note that 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 informa-
tion. 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” or “Full Off” modes.
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.
Ready Alert Braking (RAB)
Ready Alert Braking may reduce the time required to reach
full braking during emergency braking situations. It antici-
pates when an emergency braking situation may occur by
monitoring how fast the throttle is released by the driver.
The EBC will prepare the brake system for a panic stop.
Rain Brake Support (RBS)
Rain Brake Support may improve braking performance in
wet conditions. It will periodically apply a small amount of
brake pressure to remove any water buildup on the front
brake rotors. It functions when the windshield wipers are
in LO or HI speed. When Rain Brake Support is active,
there is no notification to the driver and no driver interac-
tion is required.
Dynamic Steering Torque (DST)
Dynamic Steering Torque is a feature of the ESC and EPS
modules that provides torque at the steering wheel for
certain driving conditions in which the ESC module is
detecting vehicle instability. The torque that the steering
wheel receives is only meant to help the driver realize
optimal steering behavior in order to reach/maintain vehicle
stability. The only notification the driver receives that the
feature is active is the torque applied to the steering wheel.
178 SAFETY

•The cluster icon and switch lamp will flash for several
seconds then extinguish when the driver pushes the SSC
switch but enable conditions are not met.
• The cluster icon and switch lamp will flash for several
seconds then extinguish when SSC disables due to
excess speed.
• The cluster icon and switch lamp will flash then extin-
guish when SSC deactivates due to overheated brakes.
WARNING!
SSC is only intended to assist the driver in controlling
vehicle speed when driving in off road conditions. The
driver must remain attentive to the driving conditions
and is responsible for maintaining a safe vehicle speed.
AUXILIARY DRIVING SYSTEMS
Blind Spot Monitoring (BSM) — If Equipped
The Blind Spot Monitoring (BSM) system uses two radar-
based sensors, located inside the rear bumper fascia, to
detect highway licensable vehicles (automobiles, trucks,
motorcycles, etc.) that enter the blind spot zones from the
rear/front/side of the vehicle.
Rear Detection Zones
184 SAFETY

When the vehicle is started, the BSM warning light will
momentarily illuminate in both outside rear view mirrors
to let the driver know that the system is operational. The
BSM system sensors operate when the vehicle is in any
forward gear or REVERSE and enters stand-by mode when
the vehicle is in PARK.
The BSM detection zone covers approximately one lane
width on both sides of the vehicle 12 ft (3.8 m). The zone
length starts at the outside mirror and extends approxi-
mately 10 ft (3 m) beyond the rear bumper of the vehicle.
The BSM system monitors the detection zones on both
sides of the vehicle when the vehicle speed reaches ap-
proximately 6 mph (10 km/h) or higher and will alert the
driver of vehicles in these areas.
NOTE:
•
The BSM system does NOT alert the driver about rapidly
approaching vehicles that are outside the detection zones.
• The BSM system detection zone does NOT change if
your vehicle is towing a trailer. Therefore, visually verify
the adjacent lane is clear for both your vehicle and trailer
before making a lane change. If the trailer or other object
(i.e., bicycle, sports equipment) extends beyond the side of your vehicle, this may result in the BSM warning light
remaining illuminated the entire time the vehicle is in a
forward gear.
The area on the rear fascia where the radar sensors are
located must remain free of snow, ice, and dirt/road
contamination so that the BSM system can function prop-
erly. Do not block the area of the rear fascia where the radar
sensors are located with foreign objects (bumper stickers,
bicycle racks, etc.)
The BSM system will provide a visual alert in the appro-
priate side view mirror based on a detected object. If the
turn signal is then activated, and it corresponds to an alert
present on that side of the vehicle, an audible chime will
also be sounded. Whenever a turn signal and detected
object are present on the same side at the same time, both
the visual and audio alerts will be issued. In addition to the
audible alert the radio (if on) will also be muted.

SAFETY 185

RCP monitors the rear detection zones on both sides of the
vehicle, for objects that are moving toward the side of the
vehicle with a minimum speed of approximately 3 mph
(5 km/h), to objects moving a maximum of approximately
20 mph (32 km/h), such as in parking lot situations.
NOTE:In a parking lot situation, oncoming vehicles can be
obscured by vehicles parked on either side. If the sensors
are blocked by other structures or vehicles, the system will
not be able to alert the driver.
When RCP is on and the vehicle is in REVERSE, the driver
is alerted using both the visual and audible alarms, includ-
ing reducing the radio volume.
WARNING!
RCP is not a Back Up Aid system. It is intended to be
used to help a driver detect an oncoming vehicle in a
parking lot situation. Drivers must be careful when
backing up, even when using RCP. Always check
carefully behind your vehicle, look behind you, and be
sure to check for pedestrians, animals, other vehicles,
obstructions, and blind spots before backing up. Fail-
ure to do so can result in serious injury or death.
Modes Of Operation
Three selectable modes of operation are available in the
Uconnect System. Refer to “Uconnect Settings” in “Multi-
media” for further information.
Blind Spot Alert Lights Only
When operating in Blind Spot Alert mode, the BSM system
will provide a visual alert in the appropriate side view
mirror based on a detected object. However, when the
system is operating in Rear Cross Path (RCP) mode, the
system will respond with both visual and audible alerts
when a detected object is present. Whenever an audible
alert is requested, the radio is muted.
Blind Spot Alert Lights/Chime
When operating in Blind Spot Alert Lights/Chime mode,
the BSM system will provide a visual alert in the appro-
priate side view mirror based on a detected object. If the
turn signal is then activated, and it corresponds to an alert
present on that side of the vehicle, an audible chime will
also be sounded. Whenever a turn signal and detected
object are present on the same side at the same time, both
the visual and audible alerts will be issued. In addition to
the audible alert the radio (if on) will also be muted.
