vehicle motion. In order to minimize potential for
damage, secure all cargo to prevent movement and
protect inside surfaces of bin from heavy/sharp
objects with appropriate padding.
CAUTION!
Failure to follow the following items could cause
damage to the vehicle:
Assure that all cargo inside the storage bins is
properly secured.

the following:

1. Make sure the center handle is unlocked using the
vehicle key fob and rotate the center handle
vertically to release the divider side gates.

damage:
Cargo must be secured.
 Do not exceed cargo load rating of your vehicle.
 Secure all loads to truck utilizing cargo tie downs.
 Extender should not be used as cargo tie down.
 When vehicle is in motion do not exceed 150 lb
(68 kg) load on the tailgate.
 The bed extender is not intended for off road use.

Failure to follow this procedure can also damage the
vehicle and the Tonneau Cover.
CAUTION!
It is the driver’s responsibility to ensure the Tonneau
Cover is properly installed on the vehicle. Failure to
follow this procedure can result in detachment of the
Tonneau Cover from the vehicle and/or damage to the

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
Úpage 108.
The electrical loads that may be switched off (if equipped),
and vehicle functions which can be affected by load
reduction:
 Heated Seats / Vented Seats / Heated Wheel
 Rear Defroster And Heated Mirrors
 HVAC System
 115 Volts AC Power Inverter System
 Audio and Telematics System
Loss of the battery charge may indicate one or more of the
following conditions:
 The charging system cannot deliver enough electrical
power to the vehicle system because the electrical
loads are larger than the capability of charging system.
The charging system is still functioning properly.
 Turning on all possible vehicle electrical loads
(e.g. HVAC to max settings, exterior and interior lights,
overloaded power outlets +12 Volts, 115 Volts AC, USB
ports) during certain driving conditions (city driving,
towing, frequent stopping). 
Installing options like additional lights, upfitter
electrical accessories, audio systems, alarms and
similar devices.
 Unusual driving cycles (short trips separated by long
parking periods).
 The vehicle was parked for an extended period of time
(weeks, months).
 The battery was recently replaced and was not charged
completely.
 The battery was discharged by an electrical load left on
when the vehicle was parked.
 The battery was used for an extended period with the
engine not running to supply radio, lights, chargers,
+12 Volt portable appliances like vacuum cleaners,
game consoles and similar devices.
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, 115 Volts AC, USB ports.
 Check HVAC settings (blower, temperature).
 Check the audio settings (volume). After a trip:

Check if any aftermarket equipment was installed
(additional 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
instrument panel together with a dedicated message
and/or acoustic signal when applicable. These indications
are indicative 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 telltales 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.

Oil Temperature Warning Light
This warning light will illuminate to indicate the
engine oil temperature is high. If the light turns
on while driving, stop the vehicle and shut off
the engine as soon as possible. Wait for oil
temperature to return to normal levels.
Seat Belt Reminder Warning Light
This warning light indicates when the driver or
passenger seat belt is unbuckled. When the
ignition is first placed in the ON/RUN or ACC/
ON/RUN position and if the driver’s seat belt is
unbuckled, a chime will sound and the light will turn on.
When driving, if the driver or front passenger seat belt
remains unbuckled, the Seat Belt Reminder Light will flash
or remain on continuously and a chime will sound
Úpage 282.
Tailgate Open Warning Light
This warning light will illuminate when the
tailgate is open.
NOTE:If the vehicle is moving, there will also be a single chime.
Trailer Brake Disconnected Warning Light
This warning light will illuminate when the
Trailer Brake has been disconnected.
Transmission Temperature Warning
Light — If Equipped
This warning light will illuminate to warn of a
high transmission fluid temperature. This may
occur with strenuous usage such as trailer
towing. If this light turns on, stop the vehicle
and run the engine at idle or slightly faster, with the
transmission in PARK or NEUTRAL, until the light turns off.
Once the light turns off, you may continue to drive
normally.
Vehicle Security Warning Light —
If Equipped
This light will flash at a fast rate for
approximately 15 seconds when the vehicle
security system is arming, and then will flash
slowly until the vehicle is disarmed.
YELLOW WARNING LIGHTS
Adaptive Cruise Control (ACC) Fault
Warning Light — If Equipped
This warning light will illuminate to indicate a
fault in the ACC system. Contact an authorized
dealer for service
Úpage 145.
Air Suspension Fault Warning Light —
If Equipped
This light will illuminate when a fault is
detected with the air suspension system.
Anti-Lock Brake System (ABS)
Warning Light
This warning light monitors the ABS. The light
will turn on when the ignition is placed in the
ON/RUN or ACC/ON/RUN position and may
stay on for as long as four seconds.
If the ABS light remains on or turns on while driving, then
the Anti-Lock portion of the brake system is not
functioning and service is required as soon as possible.
However, the conventional brake system will continue to
operate normally, assuming the Brake Warning Light is not
also on.
If the ABS light does not turn on when the ignition is placed
in the ON/RUN or ACC/ON/RUN position, have the brake
system inspected by an authorized dealer.
WARNING!
If you continue operating the vehicle when the
Transmission Temperature Warning Light is illuminated
you could cause the fluid to boil over, come in contact
with hot engine or exhaust components and cause a
fire.
CAUTION!
Continuous driving with the Transmission Temperature
Warning Light illuminated will eventually cause severe
transmission damage or transmission failure.
