Carefully follow these warnings to help prevent personal
injury or damage to your vehicle:
CAUTION!
• Ensure cargo bin lids are closed and latched before moving or driving vehicle.
• Loads applied to the top of the bin lid should be mini -
mized to prevent damage to the lid and latching/
hinging mechanisms.
• Damage to the RamBox bin may occur due to heavy/ sharp objects placed in bin that shift due to 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 appro -
priate padding.
WARNING!
• Always close the storage bin covers when your vehicle is unattended.
• Do not allow children to have access to the storage bins. Once in the storage bin, young children may not be able
to escape. If trapped in the storage bin, children can die
from suffocation or heat stroke.
• In an accident, serious injury could result if the storage bin covers are not properly latched.
• Do not drive the vehicle with the storage bin covers open.
• Keep the storage bin covers closed and latched while the vehicle is in motion.

NOTE:
This feature is available for vehicles both equipped, or not
equipped, with a RamBox.
There are two adjustable cleats on each side of the bed that
can be used to assist in securing cargo.Adjustable Cleats
Each cleat must be located and tightened down in one of the
detents, along either rail, in order to keep cargo properly
secure. To move the cleat to any position on the rail, turn the nut
counterclockwise, approximately three turns. Then pull out
on the cleat and slide it to the detent nearest the desired loca
-
tion. Make sure the cleat is seated in the detent and tighten
the nut.

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.

The light will remain on until the cause is corrected.
NOTE:
The light may flash momentarily during sharp cornering
maneuvers, which change fluid level conditions. The vehicle
should have service performed, and the brake fluid level
checked.
If brake failure is indicated, immediate repair is necessary.
Vehicles equipped with the Anti-Lock Brake System (ABS)
are also equipped with Electronic Brake Force Distribution
(EBD). In the event of an EBD failure, the Brake Warning
Light will turn on along with the ABS Light. Immediate
repair to the ABS system is required.
Operation of the Brake Warning Light can be checked by
turning the ignition switch from the OFF position to the ON/
RUN position. The light should illuminate for approximately
two seconds. The light should then turn off unless theparking brake is applied or a brake fault is detected. If the
light does not illuminate, have the light inspected by an
authorized dealer.
The light also will turn on when the parking brake is applied
with the ignition switch in the ON/RUN position.
NOTE:
This light shows only that the parking brake is applied. It
does not show the degree of brake application.
— Hood Open Warning Light
This warning light will illuminate when the hood is ajar/
open and not fully closed.
NOTE:
If the vehicle is moving, there will also be a single chime.
— Vehicle Security Warning Light — If Equipped

This light will flash at a fast rate for approximately 15 seconds
when the vehicle security alarm is arming, and then will flash
slowly until the vehicle is disarmed.

WARNING!
Driving a vehicle with the red brake light on is
dangerous. Part of the brake system may have failed. It
will take longer to stop the vehicle. You could have a
collision. Have the vehicle checked immediately.

ONBOARD DIAGNOSTIC SYSTEM — OBD II
Your vehicle is equipped with a sophisticated Onboard
Diagnostic system called OBD II. This system monitors the
performance of the emissions, engine, and transmission
control systems. When these systems are operating properly,
your vehicle will provide excellent performance and fuel
economy, as well as engine emissions well within current
government regulations.
If any of these systems require service, the OBD II system
will turn on the Malfunction Indicator Light (MIL). It will
also store diagnostic codes and other information to assist
your service technician in making repairs. Although your
vehicle will usually be drivable and not need towing, see an
authorized dealer for service as soon as possible.
Onboard Diagnostic System (OBD II) Cybersecurity
Your vehicle is required to have an Onboard Diagnostic
system (OBD II) and a connection port to allow access to
information related to the performance of your emissions
controls. Authorized service technicians may need to access
this information to assist with the diagnosis and service of
your vehicle and emissions system.

For further information, refer to “Cybersecurity” in “Multi-
media”.

CAUTION!
• Prolonged driving with the MIL on could cause further damage to the emission control system. It could also
affect fuel economy and driveability. The vehicle must
be serviced before any emissions tests can be
performed.
• If the MIL is flashing while the vehicle is running, severe catalytic converter damage and power loss will
soon occur. Immediate service is required.
WARNING!
• ONLY an authorized service technician should connect equipment to the OBD II connection port in order to
read the VIN, diagnose, or service your vehicle.
• If unauthorized equipment is connected to the OBD II connection port, such as a driver-behavior tracking
device, it may:
• Be possible that vehicle systems, including safety related systems, could be impaired or a loss of
vehicle control could occur that may result in an
accident involving serious injury or death.
• Access, or allow others to access, information stored in your vehicle systems, including personal infor -
mation.
