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.
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 “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 affected by load
reduction:
• Heated Seat/Vented Seats/Heated Wheel
• Heated/Cooled Cup Holders — If Equipped
• Rear Defroster And Heated Mirrors
• HVAC System

— Low Washer Fluid Warning Light — If
Equipped
This indicator will illuminate when the windshield washer
fluid is low.
— Tire Pressure Monitoring System (TPMS)
Warning Light
The warning light switches on and a message is displayed
to indicate that the tire pressure is lower than the recom-
mended value and/or that slow pressure loss is occurring.
In these cases, optimal tire duration and fuel consumption
may not be guaranteed.
Should one or more tires be in the condition mentioned
above, the display will show the indications corresponding
to each tire in sequence.
CAUTION!
Do not continue driving with one or more flat tires as
handling may be compromised. Stop the vehicle,
avoiding sharp braking and steering. If a tire puncture
occurs, repair immediately using the dedicated tire
repair kit and contact your authorized dealer as soon as
possible. Each tire, including the spare (if provided), should be
checked monthly when cold and inflated to the inflation
pressure recommended by the vehicle manufacturer on the
vehicle placard or tire inflation pressure label. (If your
vehicle has tires of a different size than the size indicated
on the vehicle placard or tire inflation pressure label, you
should determine the proper tire inflation pressure for
those tires.)
As an added safety feature, your vehicle has been
equipped with a tire pressure monitoring system (TPMS)
that illuminates a low tire pressure telltale when one or
more of your tires is significantly under-inflated. Accord-
ingly, when the low tire pressure telltale illuminates, you
should stop and check your tires as soon as possible, and
inflate them to the proper pressure. Driving on a signifi-
cantly 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 main-
tain correct tire pressure, even if under-inflation has not
reached the level to trigger illumination of the TPMS low
tire pressure telltale.

Towing With HSA
HSA will also provide assistance to mitigate roll back while
towing a trailer.
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 resum-
ing acceleration, manually activate the trailer brake
or apply more vehicle brake pressure prior to releas-
ing 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
collision or serious personal injury.
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
“Uconnect Settings” in “Multimedia” for further infor-
mation.
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.

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
illuminate. 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. Mul-
tiple momentary button pushed may be required to return
to ESC On.
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.
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.

CAUTION!(Continued)
•Using aftermarket tire sealants may cause the Tire
Pressure Monitoring System (TPMS) sensor to be-
come inoperable. After using an aftermarket 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 always
reinstall the valve stem cap. This will prevent mois-
ture and dirt from entering the valve stem, which
could damage the TPMS 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 pressure
gauge, even if under-inflation has not reached the level
to trigger illumination of the TPM Telltale Light.
• Seasonal temperature changes will affect tire pressure,
and the TPMS will monitor the actual tire pressure in the
tire.
Premium System
The Tire Pressure Monitor System (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 monthly and to
maintain the proper pressure.
The TPMS consists of the following components:
• Receiver module
• Four tire pressure monitoring sensors
• Various tire pressure monitoring system messages,
which display in the instrument cluster
174 SAFETY

•Tire pressure monitoring telltale light
Tire Pressure Monitoring Low Pressure Warnings
The “Tire Pressure Monitoring Telltale Light” will
illuminate in the instrument cluster and a chime
will sound when tire pressure is low in one or more of the
four active road tires. In addition, the instrument cluster
will display a graphic showing the pressure values of each
tire with the low tire pressure values in a different color. An
Inflate to XX message will also be displayed. Should this occur, you should stop as soon as possible and
inflate the tires with a low pressure condition (those in a
different color in the instrument cluster graphic) to the
vehicle’s recommended cold placard pressure inflation
value as shown in the
Inflate to XXmessage. Once the
system receives the updated tire pressures, the system will
automatically update, the graphic display in the instru-
ment cluster will return to it’s original color, and the “Tire
Pressure Monitoring Telltale Light” will turn off. 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.
Service TPMS Warning
If a system fault is detected, the “Tire Pressure Monitoring
Telltale Light” will flash on and off for 75 seconds and then
remain on solid. The system fault will also sound a chime.
In addition, the instrument cluster will display a SERVICE
TPM SYSTEM message for a minimum of five seconds and
then display dashes (- -) in place of the pressure value to
indicate which sensor is not being received.
“LOW TIRE PRESSURE” Message

SAFETY 175

If the ignition switch is cycled, this sequence will repeat,
providing the system fault still exists. If the system fault no
longer exists, the “Tire Pressure Monitoring Telltale Light”
will no longer flash, and theSERVICE TPM SYSTEM
message will no longer display, and a pressure value will
display in place of the dashes. A system fault can occur due
to any of the following:
• Signal interference due to electronic devices or driving
next to facilities emitting the same radio frequencies as
the TPM sensors. •
Installing aftermarket window tinting that contains ma-
terials that may block radio wave signals.
• Accumulation of snow or ice around the wheels or
wheel housings.
• Using tire chains on the vehicle.
• Using wheels/tires not equipped with TPM sensors.
A system fault may occur due to an incorrect TPM sensor
location condition. When a system fault occurs due to an
incorrect TPM sensor location, the “Tire Pressure Monitor-
ing Telltale Light” will flash on and off for 75 seconds and
then remain on solid. The system fault will also sound a
chime. In addition, the instrument cluster will display a
“Tire Pressure Temporarily Unavailable” message in place
of the tire pressure display screen. If the ignition switch is
cycled, this sequence will repeat, providing the system
fault still exists. If the system fault no longer exists, the
“Tire Pressure Monitoring Telltale Light” will no longer
flash and the tire pressure display screen will be displayed
showing the tire pressure values the correct locations.

Vehicles With Non Matching Full Size Spare Or Compact
Spare
•The non matching full size spare or compact spare tire
does not have a TPM sensor. Therefore, the TPMS will
not monitor the pressure in the non matching full size
spare or compact spare tire.
• If you install the non matching full size spare or compact
spare tire in place of a road tire that has a pressure below
the low-pressure warning limit, upon the next ignition
switch cycle, the TPM Telltale Light and a “LOW TIRE”
message will remain ON and a chime will sound. In
addition, the graphic in the instrument cluster will still
display a pressure value in a different color.
• After driving the vehicle for up to 20 minutes above
15 mph (24 km/h), the TPM Telltale 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 a minimum of five seconds
and then display dashes (- -) in place of the pressure
value.
• For each subsequent ignition switch cycle, a chime will
sound, the TPM Telltale Light will flash on and off for 75
seconds and then remain on solid, and the instrument cluster will display a
SERVICE TPM SYSTEM message
for a minimum of five seconds and then display dashes
(- -) in place of the pressure value.
• Once you repair or replace the original road tire and
reinstall it on the vehicle in place of the non matching
full size spare or compact spare, the TPMS will update
automatically. In addition, the TPM Telltale Light will
turn OFF and the graphic in the instrument cluster will
display a new pressure value instead of dashes (- -), 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.
