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 Some Systems May Have Reduced Power” will
appear in the instrument cluster.
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 reduction.
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 “Getting To Know Your Instru -
ment Panel” for further information.
The electrical loads that may be switched off (if equipped),
and vehicle functions which can be affected by load reduc -
tion:
• Heated Seats/Vented Seats/Heated Wheel
• Rear Defroster And Heated Mirrors
• HVAC System
• 115V AC Power Inverter System
• Audio and Telematics System

— Electronic Stability Control (ESC) Active Warning
Light — If Equipped
This warning light will indicate when the Electronic Stability
Control system is Active. The “ESC Indicator Light” in the
instrument cluster will come on when the ignition is placed
in the ON/RUN or ACC/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 warning light remains on after several ignition
cycles, and the vehicle has been driven several miles (kilome -
ters) at speeds greater than 30 mph (48 km/h), see an autho - rized 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 ACC/ON/RUN position.
• 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.CAUTION!
Prolonged driving with the Malfunction Indicator Light
(MIL) on could cause damage to the vehicle control
system. It also could affect fuel economy and
driveability. If the MIL is flashing, severe catalytic
converter damage and power loss will soon occur.
Immediate service is required.

Towing With HSA
HSA will also provide assistance to mitigate roll back while
towing a trailer. Disabling And Enabling HSA
This feature can be turned on or turned off. To change the
current setting, proceed as follows:
• If disabling HSA using your instrument cluster display,
refer to “Instrument Cluster Display” in “Getting To Know
Your Instrument Panel” for further information.
• If disabling HSA using Uconnect Settings, refer to “Ucon -
nect Settings” in “Multimedia” for further information.
For vehicles not equipped with an instrument cluster
display, perform the following steps:
1. Center the steering wheel (front wheels pointing straight
forward).
2. Shift the transmission into PARK.
3. Apply the parking brake.
4. Start the engine.
5. Rotate the steering wheel slightly more than one-half turn
to the left.WARNING!
• If you use a trailer brake controller with your trailer, the
trailer brakes may be activated and deactivated with
the brake switch. If so, there may not be enough brake
pressure to hold both the vehicle and the trailer on a
hill when the brake pedal is released. In order to avoid
rolling down an incline while resuming acceleration,
manually activate the trailer brake or apply more
vehicle brake pressure prior to releasing the brake
pedal.
• HSA is not a parking brake. Always apply the parking
brake fully when exiting your vehicle. Also, be certain
to place the transmission in PARK.
• Failure to follow these warnings can result in a colli -
sion or serious personal injury. 4

SAFETY 167
(Continued)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.
ESC Operating Modes
NOTE:
Depending upon model and mode of operation, the ESC
system may have multiple operating modes.
ESC On
This is the normal operating mode for the ESC. Whenever
the vehicle is started, the ESC system will be in this mode.
This mode should be used for most driving conditions. Alter -
nate ESC modes should only be used for specific reasons as
noted in the following paragraphs.WARNING!
• Electronic Stability Control (ESC) cannot prevent the
natural laws of physics from acting on the vehicle, nor
can it increase the traction afforded by prevailing road
conditions. ESC cannot prevent accidents, including
those resulting from excessive speed in turns, driving
on very slippery surfaces, or hydroplaning. ESC also
cannot prevent accidents resulting from loss of vehicle
control due to inappropriate driver input for the condi -
tions. Only a safe, attentive, and skillful driver can
prevent accidents. The capabilities of an ESC equipped
vehicle must never be exploited in a reckless or
dangerous manner which could jeopardize the user’s
safety or the safety of others. • Vehicle modifications, or failure to properly maintain
your vehicle, may change the handling characteristics of
your vehicle, and may negatively affect the performance
of the ESC system. Changes to the steering system,
suspension, braking system, tire type and size or wheel
size may adversely affect ESC performance. Improperly
inflated and unevenly worn tires may also degrade ESC
performance. Any vehicle modification or poor vehicle
maintenance that reduces the effectiveness of the ESC
system can increase the risk of loss of vehicle control,
vehicle rollover, personal injury and death. WARNING! (Continued)

168 SAFETY
(Continued)Partial Off
The “Partial Off” mode is intended for times when a more
spirited driving experience is desired. This mode may
modify TCS and ESC thresholds for activation, which allows
for more wheel spin than normally allowed. This mode may
be useful if the vehicle becomes stuck.
To enter the “Partial Off” mode, momentarily push the “ESC
Off” switch and the “ESC Off Indicator Light” will illumi -
nate. To turn the ESC on again, momentarily push the “ESC
Off” switch and the “ESC Off Indicator Light” will turn off.
NOTE:
For vehicles with multiple partial ESC modes a momentary
button push will toggle the ESC mode. Multiple momentary
button pushed may be required to return to ESC On. Full Off — If Equipped
This mode is intended for off-highway or off-road use only
and should not be used on any public roadways. In this
mode, TCS and ESC features are turned OFF. To enter the
“Full Off” mode, push and hold the “ESC Off” switch for five
seconds while the vehicle is stopped with the engine
running. After five seconds, a chime will sound, the “ESC Off
Indicator Light” will illuminate, and the “ESC OFF” message
will display in the instrument cluster. To turn ESC ON again,
momentarily push the “ESC Off” switch.
NOTE:
System may switch from ESC “Full Off” to “Partial Off”
mode when vehicle exceeds a predetermined speed. When
the vehicle speed slows below the predetermined speed the
system will return to ESC “Full Off”.
ESC modes may also be affected by drive modes if so
equipped.WARNING!
• When in “Partial Off” mode, the TCS functionality of
ESC, (except for the limited slip feature described in
the TCS section), has been disabled and the “ESC Off
Indicator Light” will be illuminated. When in “Partial
Off” mode, the engine power reduction feature of TCS
is disabled, and the enhanced vehicle stability offered
by the ESC system is reduced. • Trailer Sway control (TSC) is disabled when the ESC
system is in the “Partial Off” mode. WARNING! (Continued)

SAFETY 169
ESC Activation/Malfunction Indicator Light And ESC
OFF Indicator Light
The “ESC Activation/Malfunction Indicator Light”
in the instrument cluster will come on when the igni -
tion is turned to the ON mode. It should go out with
the engine running. If the “ESC Activation/Malfunction
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 an authorized dealer as
soon as possible to have the problem diagnosed and
corrected.
The “ESC Activation/Malfunction Indicator Light” (located
in the instrument cluster) starts to flash as soon as the tires
lose traction and the ESC system becomes active. The “ESC
Activation/Malfunction Indicator Light” also flashes when
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 condi -
tions.
NOTE:
• The “ESC Activation/Malfunction Indicator Light” and
the “ESC OFF Indicator Light” come on momentarily each
time the ignition is turned ON.
• Each time the ignition is turned ON, 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 following the maneuver that caused
the ESC activation.WARNING!
• In the ESC “Full Off” mode, the engine torque reduc -
tion and stability features are disabled. Therefore,
enhanced vehicle stability offered by the ESC system is
unavailable. In an emergency evasive maneuver, the
ESC system will not engage to assist in maintaining
stability. ESC “Full Off” mode is intended for
off-highway or off-road use only.
• The Electronic Stability Control (ESC) cannot prevent
the natural laws of physics from acting on the vehicle,
nor can it increase the traction afforded by prevailing
road conditions. ESC cannot prevent all accidents,
including those resulting from excessive speed in
turns, driving on very slippery surfaces, or hydro -
planing. ESC also cannot prevent collisions. 4

• HDC detects excessive brake temperature. Feedback To The Driver
The instrument cluster has an HDC icon and the HDC switch
has an LED icon, which offers feedback to the driver about
the state HDC is in.
• The cluster icon and switch lamp will illuminate and
remain on solid when HDC is enabled or activated. This is
the normal operating condition for HDC.
• The cluster icon and switch lamp will flash for several
seconds then extinguish when the driver pushes the HDC
switch but enable conditions are not met.
• The cluster icon and switch lamp will flash for several
seconds then extinguish when HDC disables due to excess
speed.
• The cluster icon and switch lamp will flash when HDC
deactivates due to overheated brakes. The flashing will
stop and HDC will activate again once the brakes have
cooled sufficiently.
WARNING!
HDC is only intended to assist the driver in controlling
vehicle speed when descending hills. The driver must
remain attentive to the driving conditions and is
responsible for maintaining a safe vehicle speed. 4
