•Installing options like additional lights, upfitter electri-
cal accessories, audio systems, alarms and similar de-
vices.
• 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,
+12V 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 +12V, 115V AC, USB ports
– Check HVAC settings (blower, temperature)
– Check the audio settings (volume)
After a trip:
• Check if any aftermarket equipment was installed (ad-
ditional lights, upfitter electrical accessories, audio sys-
tems, 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 mes-
sage is still present during consecutive trips and the
evaluation of the vehicle and driving pattern did not
help to identify the cause.

Power Steering Fluid Check — 2500/3500 Models
Checking the power steering fluid level at a defined service
interval is not required. The fluid should only be checked
if a leak is suspected, abnormal noises are apparent,
and/or the system is not functioning as anticipated. Coor-
dinate inspection efforts through an authorized dealer.
CAUTION!
Do not use chemical flushes in your power steering
system as the chemicals can damage your power steer-
ing components. Such damage is not covered by the
New Vehicle Limited Warranty.
WARNING!
Fluid level should be checked on a level surface and
with the engine off to prevent injury from moving
parts and to ensure accurate fluid level reading. Do not
overfill. Use only manufacturer’s recommended power
steering fluid.
If necessary, add fluid to restore to the proper indicated
level. With a clean cloth, wipe any spilled fluid from all
surfaces. Refer to “Fluids, Lubricants, And Genuine Parts”
in “Maintaining Your Vehicle” for further information.
FUEL SAVER TECHNOLOGY 5.7L/6.4L ENGINES

This feature offers improved fuel economy by shutting off
four of the engine’s eight cylinders during light load and
cruise conditions. The system is automatic with no driver
inputs or additional driving skills required.
NOTE: This system may take some time to return to full
functionality after a battery disconnect.
PARKING BRAKE
Before leaving the vehicle, make sure that the parking
brake is fully applied. Also, be certain to leave the trans-
mission in PARK.
The foot operated parking brake is located below the lower
left corner of the instrument panel. To apply the park
brake, firmly push the park brake pedal fully. To release the
parking brake, pull the parking brake release handle.
492 STARTING AND OPERATING
HOISTING
A conventional floor jack may be used at the jacking
locations. Refer to the graphics that show jacking locations.
However, a floor jack or frame hoist must never be used on
any other parts of the underbody.
CAUTION!
Never use a floor jack directly under the differential
housing of a loaded truck or damage to your vehicle
may result.
JUMP-STARTING PROCEDURES
If your vehicle has a discharged battery, it can be jump-
started using a set of jumper cables and a battery in another
vehicle or by using a portable battery booster pack. Jump-
starting can be dangerous if done improperly, so please
follow the procedures in this section carefully.
NOTE:When using a portable battery booster pack, follow
the manufacturer ’s operating instructions and precautions.
WARNING!
Do not attempt jump-starting if the battery is frozen. It
could rupture or explode and cause personal injury.
CAUTION!
Do not use a portable battery booster pack or any other
booster source with a system voltage greater than 12
Volts or damage to the battery, starter motor, alternator
or electrical system may occur.
Preparations For Jump-Start
The battery in your vehicle is located in the front of the
engine compartment, behind the left headlight assembly.
NOTE: The positive battery post may be covered with a
protective cap if equipped. Lift up on the cap to gain access
to the positive battery post. Do not jump off fuses. Only
jump directly off positive post which has a positive (+)
symbol on or around the post.
618 WHAT TO DO IN EMERGENCIES
CAUTION!
•When installing the power distribution center cover,
it is important to ensure the cover is properly posi-
tioned and fully latched. Failure to do so may allow
water to get into the power distribution center and
possibly result in an electrical system failure.
• When replacing a blown fuse, it is important to use
only a fuse having the correct amperage rating. The
use of a fuse with a rating other than indicated may
result in a dangerous electrical system overload. If a
properly rated fuse continues to blow, it indicates a
problem in the circuit that must be corrected.
VEHICLE STORAGE
If you are storing your vehicle for more than 21 days, we
recommend that you take the following steps to minimize
the drain on your vehicle’s battery:
• Disconnect the negative cable from battery.
• Any time you store your vehicle or keep it out of service
(i.e., vacation) for two weeks or more, run the air
conditioning system at idle for about five minutes in the
fresh air and high blower setting. This will ensure
adequate system lubrication to minimize the possibility
of compressor damage when the system is started again.
