HYBRID VEHICLE FREQUENTLY ASKED QUESTIONS Answer
Question
The high voltage battery is electrically isolated from the rest of the
vehicle when the key is off. When you switch the key on, high voltage
contactors inside the battery are closed to make the electricity avail-
able to the motor and generator and enable the vehicle to drive. The
clicks are the sound of these contactors as they close and open during start up and shut down.
What are the series of clicks from the cargo area when I first turn the
key in the ignition?
The vehicle's computer will determine if an engine start is requiredat key-on. Silent key start will start the engine if it is necessary for
cabin heating, windshield defrost, or if the outside temperature is low.
Why does the engine sometimes start at key-on?
There are several reasons the engine stays on for an extended amountof time when you first start it. One common reason is to make sure
that the emissions components are warm enough to minimize tailpipe
emissions. As the climate gets cooler, this engine-on time is extended.
Why does it take a long time before the engine shuts down?
The engine is required to turn on above this speed to protect thetransmission hardware.
Why does my engine never shut down above 85 mph (137 km/h)

Note:
If you do not add new fuel during an
18-month period, fuel freshness mode will
use fuel until approximately 1.2 gal (4.5 L) of
fuel remains in the fuel tank.
During fuel freshness mode:
• The information display will indicate fuel
freshness mode is active.
• EV Now mode will not be available.
• Most of the electric-only driving range
will be saved until fuel freshness mode
is completed.
Note: EV Now mode will become available
when less than 1.2 gal (4.5 L) of fuel remains
in the fuel tank.
Note: When the fuel level is less than
one-quarter full, refueling your vehicle will
end fuel freshness mode.
Note: We recommend you use a fuel
stabilizer if you use less than a full tank of
fuel during an 18-month period.
FUEL FILLER FUNNEL LOCATION
The fuel filler funnel is under the luggage
compartment floor covering. RUNNING OUT OF FUEL
Avoid running out of fuel because this
situation may have an adverse effect on
vehicle components.If you have run out of fuel:
•
To start the vehicle with a keyless
ignition, just start the engine. Crank time
will be longer than usual.
• Normally, adding 1 gal (3.8 L) of fuel is
enough to restart the vehicle. If the
vehicle is out of fuel and on a steep
grade, more than
1 gal (3.8 L) may be
required.
• The service engine soon indicator may
come on.
Refilling With a Portable Fuel Container WARNING:
Flow of fuel through a
fuel pump nozzle can produce static
electricity. This can cause a fire if you are
filling an ungrounded fuel container. WARNING:
Do not insert the nozzle
of a fuel container or an aftermarket funnel
into the fuel filler neck. This may damage
the fuel system filler neck or its seal and
cause fuel to run onto the ground.

Advertised Capacity
The advertised capacity is the maximum
amount of fuel that you can add to the fuel
tank after running out of fuel. Included in the
advertised capacity is an empty reserve. The
empty reserve is an unspecified amount of
fuel that remains in the fuel tank when the
fuel gauge indicates empty.
Note:
The amount of fuel in the empty
reserve varies and should not be relied upon
to increase driving range.
Fuel Economy
Your vehicle calculates fuel economy figures
through the trip computer average fuel
function. See General Information (page
110).
The first 1,000 mi (1,500 km) of driving is the
break-in period of the engine. A more
accurate measurement is obtained after
2,000 mi (3,000 km)

Noise Emissions Warranty, Prohibited
Tampering Acts and Maintenance
On January 1, 1978, Federal regulation
became effective governing the noise
emission on trucks over 10,000 lb (4,536 kg)
Gross Vehicle Weight Rating (GVWR). The
preceding statements concerning prohibited
tampering acts and maintenance, and the
noise warranty found in the Warranty Guide,
are applicable to complete chassis cabs over
10,000 lb (4,536 kg)
GVWR. CATALYTIC CONVERTER WARNING:
Do not park, idle or drive
your vehicle on dry grass or other dry
ground cover. The emission system heats
up the engine compartment and exhaust
system, creating the risk of fire. WARNING:
The normal operating
temperature of the exhaust system is very
high. Never work around or attempt to
repair any part of the exhaust system until
it has cooled. Use special care when
working around the catalytic converter.
The catalytic converter heats up to a very
high temperature after only a short period
of engine operation and stays hot after the
engine is switched off. WARNING: Exhaust leaks may result
in entry of harmful and potentially lethal
fumes into the passenger compartment. If
you smell exhaust fumes inside your
vehicle, have your vehicle inspected
immediately. Do not drive if you smell
exhaust fumes. Your vehicle has various emission control
components and a catalytic converter that
enables it to comply with applicable exhaust
emission standards.
To make sure that the catalytic converter and
other emission control components continue
to work properly:
•
Do not crank the engine for more than
10 seconds at a time.
• Do not run the engine with a spark plug
lead disconnected.
• Do not push-start or tow-start your
vehicle. Use booster cables.
See Jump
Starting the Vehicle (page 267).
• Use only the specified fuel listed.
• Do not switch the ignition off when your
vehicle is moving.
• Avoid running out of fuel.
• Have the items listed in scheduled
maintenance information performed
according to the specified schedule.
Note: Resulting component damage may
not be covered by the vehicle Warranty.

If the service engine soon indicator remains
on, have your vehicle serviced at the first
available opportunity. Although some
malfunctions detected by the OBD-II may not
have symptoms that are apparent, continued
driving with the service engine soon indicator
on can result in increased emissions, lower
fuel economy, reduced engine and
transmission smoothness and lead to more
costly repairs.
Readiness for Inspection and
Maintenance (I/M) Testing
Some state and provincial and local
governments may have
Inspection/Maintenance (I/M) programs to
inspect the emission control equipment on
your vehicle. Failure to pass this inspection
could prevent you from getting a vehicle
registration.
If the service engine soon indicator
is on or the bulb does not work,
your vehicle may need service.
See On-Board Diagnostics. Your vehicle may not pass the I/M test if the
service engine soon indicator is on or not
working properly (bulb is burned out), or if
the OBD-II system has determined that some
of the emission control systems have not
been properly checked. In this case, the
vehicle is not ready for I/M testing.
If the vehicle
’s engine or transmission has
just been serviced, or the battery has
recently run down or been replaced, the
OBD-II system may indicate that the vehicle
is not ready for I/M testing. To determine if
the vehicle is ready for I/M testing, turn the
ignition key to the on position for 15 seconds
without cranking the engine. If the service
engine soon indicator blinks eight times, it
means that the vehicle is not ready for I/M
testing; if the service engine soon indicator
stays on solid, it means that your vehicle is
ready for I/M testing.
The OBD-II system checks the emission
control system during normal driving. A
complete check may take several days.
If the vehicle is not ready for I/M testing, you
can perform the following driving cycle
consisting of mixed city and highway driving: 1. 15 minutes of steady driving on an
expressway or highway followed by 20
minutes of stop-and-go driving with at
least four 30-second idle periods.
2. Allow your vehicle to sit for at least eight
hours with the ignition off. Then, start the
vehicle and complete the above driving
cycle. The vehicle must warm up to its
normal operating temperature. Once
started, do not turn off the vehicle until
the above driving cycle is complete.
If the vehicle is still not ready for I/M testing,
you need to repeat the above driving cycle.

2. Locate the access door and remove the
plastic cover. 3. Pull the outer cover off to expose the
service disconnect cover. 4. Slide the handle on the service
disconnect outboard to the right. 5. Pull the handle toward you and remove
the circuit from the vehicle to disable the
high-voltage battery.
Reactivating the High-Voltage Battery
Note: If you have manually disconnected
your high-voltage shut off circuit you will
need to reconnect the circuit before it can
be reactivated. The vehicle detects if the
electrical system is safe and then
reactivates. HIGH VOLTAGE SHUTOFF SWITCH
The integrity of the high voltage system is
continuously monitored. After a substantial
collision or physical jolt, the high voltage
system could become deactivated. To
reinitialize the system.
1. Press the START/STOP button to turn
the ignition off.
2. Press the brake pedal and press the START/STOP
button.
3. If your vehicle is not powered on after this sequence, repeat steps 1 and 2 up
to two more times.
Note: During this process, your vehicle will
detect if the electrical system is safe and
reactivate. Once your vehicle determines
the electrical system safe, you can start your
vehicle as you would normally by either
turning the ignition key or by pressing the
brake in combination with the START/STOP
button.
Note: In the event your vehicle does not
reactivate after the third key cycle, contact
an authorized dealer.
