What to do when an electrical load reduction action
message is present (“Battery Saver On” or “Battery Saver
Mode”)
During a trip:
• Reduce power to unnecessary loads if possible:• Turn off redundant lights (interior or exterior).

• Check what may be plugged in to power outlets +12 Volts,115V AC, USB ports.

• Check HVAC settings (blower, temperature).
• Check the audio settings (volume).
After a trip:
• Check if any aftermarket equipment was installed (addi -
tional lights, upfitter electrical accessories, audio systems,
alarms) and review specifications if any (load and Ignition
Off Draw currents).
• Evaluate the latest driving cycles (distance, driving time and parking time).
• The vehicle should have service performed if the message is still present during consecutive trips and the evaluation
of the vehicle and driving pattern did not help to identify
the cause.WARNING LIGHTS AND MESSAGES
The warning/indicator lights will illuminate in the instru-
ment panel together with a dedicated message and/or
acoustic signal when applicable. These indications are indic -
ative and precautionary and as such must not be considered
as exhaustive and/or alternative to the information
contained in the Owner’s Manual, which you are advised to
read carefully in all cases. Always refer to the information in
this chapter in the event of a failure indication. All active tell -
tales will display first if applicable. The system check menu
may appear different based upon equipment options and
current vehicle status. Some telltales are optional and may
not appear.

— 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.
— LaneSense Warning Light — If Equipped
The LaneSense system provides the driver with visual and
steering torque warnings when the vehicle starts to drift out
of its lane unintentionally without the use of a turn signal.
• When the LaneSense system senses a lane drift situation, the LaneSense indicator changes from solid green to solid
yellow.
• When the LaneSense system senses the lane has been approached and is in a lane departure situation, the Lane -
Sense indicator changes from solid white/green to
flashing yellow.
• Refer to “LaneSense – If Equipped” in “Starting And Oper -
ating” for further information. — Service LaneSense Warning Light — If Equipped
This warning light will illuminate when the LaneSense
system is not operating and requires service. Please see an
authorized dealer.
— Low Washer Fluid Warning Light — If Equipped
This warning light will illuminate when the windshield
washer fluid is low.

light will turn on, and remain on until fuel is added.
A single warning chime will sound with Low Fuel Warning.
— 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.
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 illumi-
nates a low tire pressure telltale when one or more of your
tires is significantly under-inflated. Accordingly, 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 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
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 an authorized dealer as soon as
possible.

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.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 placed in the ON/RUN 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 (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.
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.

display, perform the following steps:
1. Center the steering wheel (front wheels pointing straight forward).
2. Shift the transmission into PARK (P).
3. Apply the park 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.

Trailer Length Detection
Once the trailer presence has been established. The trailer
length will be established (by making a 90 degree turn) and
then the trailer length category (example 10-20 ft (3 m to
6 m)) will be displayed. This can take up to 30 seconds after
completing the turn. NOTE:
During the same ignition cycle, if the vehicle is at a standstill
for a minimum of 90 seconds, a new “trailer detection
request” is enabled by the system once the vehicle resumes
motion.
Maximum length supported by the Trailer Merge Assist
feature is 39.5 ft (12 m). Trailer length is considered the
forward most portion of the trailer hitch to the rearward
most portion of the body, bumper, or ramp of the trailer.
Maximum width supported by the Trailer Merge Assist
feature is 8.5 ft (2.59 m). Trailer width is measured at the
widest portion of the trailer and may include wheels, tires,
