POWER INVERTERS — IF EQUIPPED
There is a 115 V (400 W) maximum inverter outlet
located on the back of the center console to
convert Direct Current (DC) to Alternating Current
(AC).
This outlet can power cellular phones, electronics
and other low power devices requiring power up to
400 W. Certain video game consoles exceed this
power limit, as will most power tools.
Power Inverter
There may also be a second 115 V (400 W)
maximum exterior power inverter located on the
rear right side of the truck bed near the tailgate.
This inverter can be turned on by the Instrument
Panel Power Inverter switch located to the left of
the steering wheel. This inverter can power cellular
phones, electronics and other low power devices
requiring power up to 400 W. Certain video game
consoles exceed this limit, as will most power
tools. The indicator light on the power inverter
switch will be illuminated when the inverter is
turned on.
CAUTION!
Do not exceed the maximum power of 160 W
(13 A) at 12 Volts. If the 160 W (13 A) power
rating is exceeded, the fuse protecting the
system will need to be replaced.
Power outlets are designed for accessory
plugs only. Do not insert any other object in
the power outlets as this will damage the
outlet and blow the fuse. Improper use of the
power outlet can cause damage not covered
by your New Vehicle Limited Warranty.
Many accessories that can be plugged in draw
power from the vehicle's battery, even when
not in use (i.e., cellular phones, etc.). Eventu -
ally, if plugged in long enough, the vehicle's
battery will discharge sufficiently to degrade
battery life and/or prevent the engine from
starting.
Accessories that draw higher power (i.e.,
coolers, vacuum cleaners, lights, etc.), will
degrade the battery even more quickly. Only
use these intermittently and with greater
caution.
After the use of high power draw accessories,
or long periods of the vehicle not being started
(with accessories still plugged in), the vehicle
must be driven a sufficient length of time to
allow the alternator to recharge the vehicle's
battery.
Power outlets are designed for accessory
plugs only. Do not hang any type of accessory
or accessory bracket from the plug. Improper
use of the power outlet can cause damage.
CAUTION!

Auxiliary Switch Connections — Under Hood Auxiliary Switch Connections – Under Instrument Panel
In addition to the four auxiliary switch wires, a
fused battery wire and ignition wire are also
located in the interior, on the passenger side under
the instrument panel.
A kit of splices and heat shrink tubing are provided
with the auxiliary switches to aid in the connection/
installation of your electrical devices.

Fluid Level Check
The fluid level is preset at the factory and does not
require adjustment under normal operating
conditions. Routine fluid level checks are not
required; therefore the transmission has no
dipstick. An authorized dealer can check your
transmission fluid level using special service tools.
If you notice fluid leakage or transmission
malfunction, visit an authorized dealer
immediately to have the transmission fluid level
checked. Operating the vehicle with an improper
fluid level can cause severe transmission damage.
Fluid And Filter Changes
Under normal operating conditions, the fluid
installed at the factory will provide satisfactory
lubrication for the life of the vehicle.Routine fluid and filter changes are not required.
However, change the fluid and filter if the fluid
becomes contaminated (with water, etc.), or if the
transmission is disassembled for any reason.
Selection Of Lubricant
It is important to use the proper transmission fluid
to ensure optimum transmission performance and
life. Use only manufacturer's specified
transmission fluid Ú
page 426. It is important to
maintain the transmission fluid at the correct level
using the recommended fluid.
NOTE:No chemical flushes should be used in any trans -
mission; only the approved lubricant should be
used.
FUSES
General Information
CAUTION!
If a transmission fluid leak occurs, visit an
authorized dealer immediately. Severe transmis -
sion damage may occur. An authorized dealer
has the proper tools to adjust the fluid level
accurately.
CAUTION!
Using a transmission fluid other than
manufacturer’s recommended fluid may cause
deterioration in transmission shift quality and/or
torque converter shudder Ú page 426.
WARNING!
When replacing a blown fuse, always use an
appropriate replacement fuse with the same
amp rating as the original fuse. Never replace
a fuse with another fuse of higher amp rating.
The use of a fuse with a rating other than indi -
cated 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. Never replace a
blown fuse with metal wires or any other mate -
rial. Failure to use proper fuses may result in
serious personal injury, fire and/or property
damage.
Before replacing a fuse, make sure that the
ignition is off and that all the other services
are switched off and/or disengaged.
If the replaced fuse blows again, contact an
authorized dealer.
23_JT_OM_EN_USC_t.book Page 382
SERVICING AND MAINTENANCE383
The fuses protect electrical systems against
excessive electrical current.
When a device does not work, you must check the
fuse element inside the blade fuse for a break/
melt.
Also, please be aware that when using power
outlets for an extended period of time with the
engine off, it may result in vehicle battery
discharge.
Blade Fuses
Power Distribution Center (PDC)
The Power Distribution Center is located in the
engine compartment near the battery. This center
contains cartridge fuses, mini fuses, and relays.
The PDC top cover is labeled with each serviceable
fuse/relay location, function, and size.If a general protection fuse for safety systems
(air bag system, braking system), power unit
systems (engine system, gearbox system) or
steering system blows, contact an authorized
dealer.
WARNING!
1 — Fuse Element
2 — Blade Fuse with a good/functional fuse
element
3 — Blade fuse with a bad/not functional fuse
element (blown fuse)
CAUTION!
When installing the power distribution center
cover, it is important to ensure the cover is
properly positioned 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.
