• On the rear of the center console (if equipped) (SuperCab and Crew
Cab models)
Do not use the power point for operating the cigarette lighter element (if
equipped).
To prevent the fuse from being blown, do not use the power point(s)
over the vehicle capacity of 12 VDC/180W. If the power point or cigar
lighter socket is not working, a fuse may have blown. Refer to Fuses and
relays in the Roadside Emergencies chapter for information on
checking and replacing fuses.
To have full capacity usage of your power point, the engine is required to
be running to avoid unintentional discharge of the battery. To prevent
the battery from being discharged:
• do not use the power point longer than necessary when the engine is
not running,
• do not leave battery chargers, video game adapters, computers and
other devices plugged in overnight or when the vehicle is parked for
extended periods.
Always keep the power point caps closed when not being used.
POWER WINDOWS (IF EQUIPPED)
WARNING: Do not leave children unattended in the vehicle and
do not let children play with the power windows. They may
seriously injure themselves.
WARNING: When closing the power windows, you should verify
they are free of obstructions and ensure that children and/or
pets are not in the proximity of the window openings.
Press and pull the window switches
to open and close windows.
• Press down (to the first detent)
and hold the switch to open.
• Pull up (to the first detent) and
hold the switch to close.
Rear Window Buffeting: When one or both of the rear windows are
open, the vehicle may demonstrate a wind throb or buffeting noise. This
noise can be alleviated by lowering a front window approximately two to
three inches.Driver Controls

UPFITTER CONTROLS (IF EQUIPPED)
Your vehicle may be equipped with
the Upfitter option package which
will provide four switches, mounted
in the center of the instrument
panel, labeled AUX 1, AUX 2, AUX 3
and AUX 4. These switches will only
operate while the ignition is in the
on position, whether the engine is
running or not. It is, however, recommended that the engine remain
running to maintain battery charge when using the Upfitter switches for
extended duration or higher current draws. (This is even more important
for vehicles with diesel engines since the glow plugs are also draining
battery power when the ignition key is in the on position.)
When switched on by the operator they provide 10 amps, 15 amps or
30 amps of electrical battery power for a variety of personal or
commercial uses.
If your vehicle is equipped with this option, there will also be a relay box
located on the driver side end of the instrument panel. See your
authorized dealer for service.
The relays are coded as shown in
the accompanying illustration. RELAY

WARNING: Loaded vehicles, with a higher center of gravity,
may handle differently than unloaded vehicles. Do not overload
your vehicle and use extra precautions, such as driving at slower
speeds, avoiding abrupt steering changes and allowing for increased
stopping distance, when driving a heavily loaded vehicle. Over-loading
or loading the vehicle improperly can deteriorate handling capability
and contribute to loss of vehicle control and vehicle rollover.
BRAKE-SHIFT INTERLOCK
This vehicle is equipped with a brake-shift interlock feature that prevents
the gearshift lever from being moved from P (Park) when the ignition is
in the 3 (on) position and the brake pedal is not pressed.
If you cannot move the gearshift lever out of P (Park) with ignition in
the on position and the brake pedal pressed, it is possible that a fuse has
blown or the vehicle’s brakelamps are not operating properly. Refer to
Fuses and relays in the Roadside Emergencies chapter.
If the fuse is not blown and the brakelamps are working properly, the
following procedure will allow you to move the gearshift lever from P
(Park):
1. Apply the parking brake. Turn the
ignition key to 1 (off), then remove
the key. Locate the access cover
plate for the brake-shift interlock
override. It is located on top of the
steering column shroud.
2. Apply the brake. Use a tool (or a
small screwdriver) to pry out the
access cover. Insert the tool into the
access hole and slide the white
override button towards the left.
Move the gear shift lever into N
(Neutral) while holding the white
override disc towards the left.
3. Start the vehicle.Driving

FUSES AND RELAYS
Fuses
If electrical components in the
vehicle are not working, a fuse may
have blown. Blown fuses are
identified by a broken wire within
the fuse. Check the appropriate
fuses before replacing any electrical
components.
Note: Always replace a fuse with one that has the specified amperage
rating. Using a fuse with a higher amperage rating can cause severe wire
damage and could start a fire.
