Features and Controls
Auxiliary Power Outlet (APO) System
The Auxiliary Power Outlet (APO) system provides
up to 2,400 watts of 120-volt AC power. With
these power outlets, you can plug in most auxiliary
electrical equipment and devices with a maximum
limit of 2,400 watts. If you try to use equipment
that requires more than the limit, a 20-amp
protection circuit will cut the power supply and a
light in the APO switch will flash along with a
Driver Information Center (DIC) message that will
flash 120V OVERLOAD. Once this occurs, the
system must be reset. See “Resetting the
Short Circuit, Overload or Ground Fault Detection
(GFD) Circuit” later in this section and DIC
Warnings and Messages on page 24 for more
information.
When running the APO, do not have the front of
the vehicle obstructed. Leave at least five feet
(1.5 m) of space between the front of the vehicle
and any other object. This will allow airflow
through the radiator and help to keep the SGCM
cooler.
There are outlets located inside the cabin and in
the truck bed. Inside the vehicle, they are
under the rear seat in the middle.
10
In the truck bed, they are located on the passenger
side near the tailgate.
The power outlets are not designed for equipment
with high initial peak starting power of greater
than 2,400 watts, such as some air compressors,
table saws, etc.
Short Circuits, Overloads and
Ground Fault Detection (GFD)
The 120-volt AC power outlets are protected
against short circuits, overloads and ground faults.
If the system detects a short or overloaded
circuit, it will immediately shut down the outlets
and the light next to the APO button will flash,
while at the same time a 120V OVERLOAD
message will appear in the Driver Information
Center (DIC). After the fault condition is corrected,
the system can be reset by pressing and
releasing the APO button. See “APO Operating
Modes” for more information on the APO button.
Short circuits may occur because a defective
extension cord or defective electrical device
is plugged into an outlet.
11
Some electrical devices, such as motor-driven
appliances and tools, have high start-up currents.
During this start-up period, the 120-volt AC
supply will attempt to start the electrical device for
up to five seconds. If the current does not fall
below the maximum 20 amp rating of the
APO within this five-second timeframe, the system
will shut down the outlets and the light next to
the APO button will flash, while at the same time a
120V OVERLOAD message in the DIC will
appear. This type of situation is unlikely, but if it
does happen, press the APO button and try to start
the electrical device again. If the electrical
device fails to start a second time, it is probably
because the device needs more start-up power
than is available.
The Ground Fault Detection (GFD) system checks
for leakage current to ground, or the truck
frame, that could potentially be a shock hazard, in
much the same way as the Ground Fault Circuit
Interrupt (GFCI) outlets protect you in your home.
The GFD self-test is automatically performed
during the activation of the APO system.
Thereafter, if the GFD system detects a significant
leakage current, it will immediately shut down
the outlets and the light next to the APO button will
flash, while at the same time a 120V GROUND
FAULT message will appear in the DIC. If this
happens, unplug all electrical devices and reset
the system by pressing the APO button. Then plug
in each electrical device individually until the
malfunctioning extension cord or electrical device
is identified.
If, after unplugging all electrical devices and
cords and resetting the system, either the
120V OVERLOAD message or the 120V GROUND
FAULT message continues to be displayed,
have the vehicle serviced.
12
APO Operating Modes
The APO system is capable of being operated in
two different modes:
• Normal mode: This is used while the vehicle
is running and in PARK (P), the vehicle is in
Auto-Stop mode, or the vehicle is moving.
• Continuous mode: This is used while the
vehicle is parked.
Normal Mode
This mode can be activated while in any
transmission gear position to supply the outlets
with 2,400 watts of 120-volt AC power.
To activate the normal mode do the following:
1. Start the engine. See “Starting Your Engine”
in the owner manual Index.
2. Press and release
the APO button,
located on the
instrument
panel, once.
Do not hold the APO button for more than
two seconds. The light next to the APO button
will come on, indicating that the system is
supplying 120-volt AC power to the outlets.
3. Connect your electrical/electronic device(s) to
the outlets. Be sure the device(s) is secure so
you can drive the vehicle safely. If you must
use extension cords, be sure to use only
®
approved extension cords.
UL
13
If the system stops supplying 120-volt AC power
unexpectedly and the APO button starts flashing,
the system has detected an overload or ground
fault condition. To reset the system see “Resetting
the Short Circuit, Overload or Ground Fault
Detection (GFD) Circuit” later in this section.
The APO system will operate in the normal mode
until you turn it off by doing one of the following:
• Pressing the APO button. The light in the
APO button will turn off.
• Turning the ignition switch to ACCESSORY or
LOCK. See “Ignition Positions” in your owner
manual Index.
Continuous Mode
This mode can be operated only when the vehicle is
not moving and the transmission is in PARK (P) and
will provide up to 2,400 watts of 120-volt AC power
to the outlets.
Continuous mode can be operated with the key
removed from the ignition. The engine will
run continuously in this mode to supply electrical
power to the APO system.
You can use the vehicle as a generator in this
mode when no electrical power outlets are
available or during instances such as power
outages. Use this mode to power critical
appliances rather than an entire circuit in a
home/building. Never connect the APO system
outlets directly to a building’s circuitry or another
power supply.
For more information on running your vehicle
while it is parked, see “Parking Over Things that
Burn,” “Engine Exhaust,” and “Running Your
Engine While You Are Parked” in your owner
manual Index.
14
To activate the continuous mode, do the following:
1. Place the transmission in PARK (P) with
the ignition in RUN and the engine running.
See “Ignition Positions” in your owner manual
Index.
2. Press and hold the
APO button, located
on the instrument
panel, for more than
two seconds.
The light next to the APO button should begin to
flash and the DIC message, 120V READY will
appear.
3. Turn the ignition key to LOCK while the light
is flashing. The light will flash for up to
30 seconds. When the ignition key has been
turned to LOCK, the light next to the APO
switch will stop flashing and remain on. The
engine will continue to run.
4. Connect your 120-volt AC electrical/electronic
device(s) to the outlets. If you must use
extension cords, be sure to use only
®
approved extension cords.
UL
15
You can remove the key from the ignition at this
point.
{CAUTION:
Leaving children in a vehicle with the
ignition key is dangerous for many
reasons. They could operate the power
windows or other controls or even make
the vehicle move. The children or others
could be badly injured or even killed.
Do not leave the keys in a vehicle with
children.
16
If the system stops supplying 120-volt AC power
unexpectedly and the light next to the APO
button starts flashing, the system has detected an
overload or ground fault condition. To reset the
system see “Resetting the Short Circuit, Overload
or Ground Fault Detection (GDF) Circuit” later
in this section.
The APO system will operate in the continuous
mode with the engine running until one of
the following occurs:
• You press the APO button. The light in the
APO button will turn off and the engine will
turn off.
• If the fuel level gets low.
A FUEL LEVEL LOW message will appear in
the DIC and the horn will sound intermittently
for five seconds every minute for five minutes.
If the vehicle is left unattended for the full
five minute warning, the engine and APO
system will shut down, unless the APO button is
pressed during the five minute warning period.
See DIC Warnings and Messages on page 24
for more information on the FUEL LEVEL LOW
message.
• An overload or ground fault condition is
detected and not reset in five minutes.
• Vehicle security is violated.
• Engine oil pressure becomes too low.
• Engine coolant temperature becomes too hot.
• The ignition key is moved out of LOCK.
This may display an OIL PRESSURE LOW DIC
warning message and chimes which is a
normal condition when the APO button was not
used to shut off the continuous mode.
• The Hybrid power system becomes too hot.
17
Resetting the Short Circuit, Overload
or Ground Fault Detection (GFD) Circuit
To reset the Short Circuit, Overload or Ground
Fault Detection (GFD) Circuit while operating
in both the normal and continuous modes, ensure
any observed fault is removed, and press the
APO button. The light next to the button will
illuminate indicating that the system is supplying
120-volt AC power to the outlets. In the case of an
engine shutdown due to a ground fault while in
the continuous mode, restart the engine by turning
the key from LOCK to START, then follow the
instructions for entering APO Continuous Mode
earlier in this section.
Starting and Operating Your Vehicle
Starting Your Vehicle
{CAUTION:
There is something about your vehicle
that can make it move suddenly, and you
or others can be seriously injured. This
can happen if the vehicle is in the Auto
Stop mode, and the shift lever is in
DRIVE (D). Because your vehicle has the
Automatic Engine Start/Stop feature, your
vehicle’s engine might seem to be shut off
when you come to a complete stop.
CAUTION: (Continued)
18
CAUTION: (Continued)
However, if you then start to exit the
vehicle, as soon as you take your foot off
the brake pedal, the engine will start again
and the vehicle can move forward. If you
are going to exit your vehicle, first shift to
PARK (P) and turn the ignition to LOCK.
Then exit.
Your vehicle has an automatic engine start/stop
feature. This feature can cause the engine to turn
off when you are applying the brake and going
less than 10 mph (16 km/h), or when you come to
a complete stop. When you take your foot off
the brake pedal, the engine will start again and you
will continue forward. However, if you are on an
incline, your vehicle may roll backwards a
short distance until the engine performs the auto
start. To be sure your vehicle will not move or roll,
always keep your foot firmly on the brake pedal
until you are ready for the vehicle to move.
Start the engine just as you would any normal
engine. Also see “Starting Your Engine” in
the Index of the owner manual for more
information on starting. After the engine is started
and has reached operating temperature, it will
shut off automatically when bringing the vehicle to
a stop — usually the engine will shut off before
a complete stop if you are braking at speeds below
about 13 mph (21 km/h). If you are pulling a
trailer and your trailer is equipped with trailer
brakes, see Towing a Trailer on page 32 for more
information.
To restart the engine during the auto stop, release
the brake pedal and the engine will start
immediately. The vehicle will operate as a normal
vehicle, until the next stop.
19
Automatic Engine Start/Stop Override
The automatic engine start/stop override
feature may cause the engine to remain running at
a complete stop or may start the engine at a
complete stop. The following are reasons
why either of these conditions may be
encountered.
The engine will stay running at a complete stop or
will automatically start from a complete stop if:
• The outside temperatures are high — usually
above 95°F (35°C). The climate control system
is working to cool the cabin in AUTO mode. See
Climate Controls on page 24.
• You release the brake pedal in DRIVE (D) or
THIRD (3) — even slightly.
• The shift lever is in NEUTRAL, REVERSE (R),
SECOND (2) or FIRST (1).
• The battery pack charge is low.
• The tow/haul mode is active.
• The transfer case is in 4LO.
• The brake pedal has been released for more
than three seconds while the vehicle is in
PARK (P).
• It is necessary to maintain 120-volt APO
operation for loads greater than 1kw.
• The hood is not fully closed.
20
Manual Override System
To manually override the automatic engine
start/stop system, press the tow/haul switch,
located on the end of the column shift lever.
When the tow/haul
mode has been
activated, this light will
come on in the
instrument cluster.
This system disables the engine from performing
the auto stop function. While not required, you
might choose to use this during frequent
start/stops, while driving on grades or in heavy
traffic.
Press the tow/haul switch again, or turn the
ignition off, to enable the auto stop function.
The indicator light on the cluster will go out.
