Initial Drive Information
Transmission
Range Selection Mode
The Range Selection Mode switch is located on the
shift lever. To enable the Range Selection feature,
move the column shift lever to the M (Manual) position.
The current range will appear next to the M. This is the
highest attainable range with all lower gears accessible.
As an example, when 3 (Third) gear is selected, 1 (First)
through 3 (Third) gears are available.
Press the plus/minus buttons, located on the steering
column shift lever, to select the desired range of
gears for current driving conditions. See Automatic
Transmission Operation in the owner manual.
Cruise control can be used while the vehicle is in
Range Selection Mode.
Four-Wheel Drive
If the vehicle has four-wheel drive, you can send
the engine's driving power to all four wheels for
extra traction. Read the following before using
four-wheel drive.
1-2

Automatic Transfer Case
The transfer case knob is located to the left of the
instrument panel cluster. You can choose among
five driving settings:
2m(Two-Wheel Drive High): This setting is used for
driving in most street and highway situations.
AUTO (Automatic Four-Wheel Drive) : This setting is
ideal for use when road surface traction conditions are
variable.
4m(Four-Wheel Drive High): Use the four-wheel high
position when you need extra traction, such as on
snowy or icy roads or in most off-road situations.
4n(Four-Wheel Drive Low) : This setting delivers
extra torque. You might choose Four-Wheel Drive Low if
you are driving off-road in deep sand, deep mud, deep
snow, and while climbing or descending steep hills.
N (Neutral) : Shift the vehicle's transfer case to
N (Neutral) only when towing the vehicle. See
Recreational Vehicle Towing or Towing Your Vehicle
in the index of the Owner Manual.
See Four-Wheel Drive on page 3‑10.
Hybrid Features
Hybrid Safety Information
This vehicle has a standard 12-volt battery and a
high-voltage hybrid battery. Only a trained service
technician with the proper knowledge and tools should
inspect, test, or replace the hybrid battery. See your
dealer/retailer if the hybrid battery needs service.
The 12-volt battery cables, in the engine compartment,
are clearly labeled. In emergency situations, first
responders can cut those cables to disable the
high-voltage hybrid battery system.
1-3

Fuel Economy Gage
United States Canada
This gage shows when the vehicle is operating at a fuel
efficient point.
By modifying driving behavior to increase the economy
time during driving, fuel mileage will be improved.
See Fuel Economy Gage on page 4‑5.
Automatic Engine Start/Stop Feature
Start the engine as you would any other engine.
See “Starting the Engine”in the owner manual for more
information on starting. The hybrid system provides
very quiet engine starting. If pulling a trailer with trailer
brakes, see Towing a Trailer
on page 5‑8 for more
information.
Auto Stop
The vehicle has an Auto Stop feature. After a
successful engine start, the engine may turn off and
operate in the Auto Stop mode.
Keep your foot firmly on the brake pedal until you are
ready for the vehicle to move.
Engine OFF and AUTO STOP modes are indicated on
the tachometer display. When the tachometer needle
indicates OFF, the engine is not running and will remain
off until the ignition key is placed in the START position
or a remote vehicle start is performed. When the
tachometer needle indicates AUTO STOP, the hybrid
system is on, the engine is not running, but may Auto
Start at any time without notice. See Tachometer
on
page 4‑4
for more information.
1-4

A chime will sound if the driver door is opened while in
Auto Stop as a reminder that the ignition switch is not in
the LOCK/OFF position. Always turn the ignition switch
to LOCK/OFF and remove the key from the ignition
switch when exiting the vehicle.
Auto Start
The vehicle also has an Auto Start feature. The engine
will remain off while in Auto Stop mode until vehicle
conditions require the engine to run. The near-instant
starting of the engine from Auto Stop mode is called
Auto Start.
EV Mode
The vehicle also has an EV mode which uses only
the electric motor to move the vehicle. With light
acceleration, the vehicle will drive in EV mode.
EV mode is unavailable when the vehicle is out of fuel.
See Starting the Vehicle in the Two‐Mode Hybrid
supplement to the owner manual.
Regenerative Braking
Regenerative braking enables the electric drive motor
to operate as a generator when coasting or braking.
Energy from the moving vehicle recharges the hybrid
battery.
The hydraulic disc brakes work with the regenerative
braking to insure effective braking.
The braking system is computer controlled and blends
the regenerative braking with the conventional hydraulic
disc brakes to meet any requirements for deceleration.
Because the controller applies the hydraulic brakes
through its high pressure accumulator, you may
occasionally hear the motor driven pump when it
recharges the system. This is normal. In the event of a
controller problem, the brake pedal may be harder to
push and the stopping distance may be longer.
See Regenerative Braking, Warning Lights, Gages, and
Indicators and Driver Information Center (DIC) in the
owner manual.
1-5

Battery
This vehicle has a standard 12-volt battery and a
high-voltage hybrid battery. When a new standard
12-volt battery is needed, see your dealer/retailer for
one that has the replacement number shown on the
original battery's label.
Only a trained service technician with the proper
knowledge and tools should inspect, test, or replace the
hybrid battery. See your dealer/retailer if the hybrid
battery needs service. See Battery on page 6‑16.
Service
Never try to do your own service on hybrid components.
You can be injured and the vehicle can be damaged if
you try to do your own service work. Service and repair
of these hybrid components should only be performed
by a trained service technician with the proper
knowledge and tools. See Doing Your Own Service
Work on page 6‑2.

Storage Areas
Power Outlet Alternating Current
The vehicle may have a power outlet that can be used
to plug in electrical equipment that uses a maximum
limit of 150 watts.
The power outlet is
located in the rear cargo
area on the driver side.
An indicator light on the outlet turns on to show it is in
use. The light comes on when the ignition is in ON/RUN
and equipment requiring less than 150 watts is plugged
into the outlet, and no system fault is detected.
The indicator light does not come on when the ignition
is in LOCK/OFF or if no equipment is plugged into
the outlet.
If equipment is connected using more than 150 watts,
or a system fault is detected, a protection circuit shuts
off the power supply and the indicator light turns off.
To reset the circuit, unplug the item and plug it back in
or turn the Retained Accessory Power (RAP) off and
then back on. The power restarts when equipment
using 150 watts or less is plugged into the outlet and a
system fault is not detected.
The power outlet is not designed for the following
electrical equipment and may not work properly if these
items are plugged into the power outlet:
.Equipment with high initial peak wattage such as:
compressor-driven refrigerators and electric
power tools.
.Other equipment requiring an extremely stable
power supply such as: microcomputer-controlled
electric blankets, touch sensor lamps, etc.
See High Voltage Devices and Wiring on page 6‑3.

Starting and Operating Your
Vehicle
Starting the Vehicle
{WARNING:
Exiting the vehicle, without first shifting into
P (Park), may cause the vehicle to move, and you
or others can be seriously injured. Because the
vehicle has the Automatic Engine Start/Stop
feature, the vehicle’s engine might seem to be
shut off when you come to a complete stop.
(Continued)
WARNING: (Continued)
However, once the brake pedal is released,
the vehicle can move. The vehicle’s engine can
also restart at any time.
Shift to P (Park) and turn the ignition to
LOCK/OFF, before exiting the vehicle.
Start the engine as you would any other engine.
See “Starting the Engine”in the owner manual for
more information on starting. If pulling a trailer with
trailer brakes, see Towing a Trailer
on page 5‑8
for more information.
3-3

Auto Stop
The vehicle has an Auto Stop feature. After a
successful engine start, the engine may turn off and
operate in the Auto Stop mode. Some of the vehicle
conditions that allow the engine to stop running and
enter the Auto Stop mode are:
.Ignition switch is in the ON/RUN position.
.The hood is closed.
.The gear selector is in P (Park), R (Reverse),
N (Neutral) or D (Drive).
.The hybrid battery is at an acceptable state of
charge.
.The hybrid battery voltage, temperature or power
limits are not exceeded. In very hot conditions,
Auto Stop may be unavailable until the hybrid
battery has cooled.
.The engine is at operating temperature.
.The vehicle may enter Auto Stop after a remote
vehicle start.
If you are on an incline, the hybrid drive motor can help
keep the vehicle from rolling backwards, even if the
engine is in Auto Stop.
With your foot off the brake and the vehicle on level
ground, the hybrid drive motor may cause the vehicle
to roll slowly forward, even when the engine is in
Auto Stop.
Keep your foot firmly on the brake pedal until you are
ready for the vehicle to move.
Engine OFF and AUTO STOP modes are indicated on
the tachometer display. When the tachometer needle
indicates OFF, the engine is not running and will remain
off until the ignition key is placed in the START position
or a remote vehicle start is performed. When the
tachometer needle indicates AUTO STOP, the hybrid
system is on, the engine is not running, but may Auto
Start at any time without notice. See Tachometer
on
page 4‑4
for more information.
A chime will sound if the driver door is opened while in
Auto Stop as a reminder that the ignition switch is not in
the LOCK/OFF position. Always turn the ignition switch
to LOCK/OFF and remove the key from the ignition
switch when exiting the vehicle.
3-4

Auto Start
The vehicle also has an Auto Start feature. The engine
will remain off while in Auto Stop mode until vehicle
conditions require the engine to run. The near-instant
starting of the engine from Auto Stop mode is called
Auto Start. Some of the vehicle conditions that may
cause the engine to Auto Start are:
.The hood is opened.
.The gear selector is in M (Manual Mode).
.The hybrid battery state of charge is too low.
.The hybrid battery voltage, temperature or power
limits are exceeded.
.A remote vehicle start has been requested.
.The engine is not at operating temperature.
.Acceleration demands require the use of the
engine.
EV Mode
The vehicle also has an Electric Vehicle (EV) mode
which uses only the electric motor to move the vehicle.
With light acceleration, the vehicle will drive in EV
mode. EV mode is unavailable when the vehicle is
out of fuel.
If increased acceleration is required, or the vehicle
reaches approximately 40 km/h (30 mph), the engine will
start automatically. The engine shuts off at speeds
below 40 km/h (25 mph) unless the transmission is in
M (Manual Mode) or Auto Stop is disabled.
During heavy acceleration, both the engine and
hybrid electric motors supply power. A sensation
similar to a transmission gear change can be felt as
the transmission changes modes. Engine RPM may
remain above 4,000 RPM for a longer period during
hard acceleration.
3-5

Automatic Transmission Operation
The vehicle has an electronic shift position indicator
within the instrument panel cluster.
There are several different positions for the shift lever.
See “Range Selection Mode”later in this section.
P (Park) : This position locks the rear wheels. It is the
best position to use when you start the engine because
the vehicle cannot move easily.
When parked on a hill, especially when the vehicle has
a heavy load, you may notice an increase in the effort to
shift out of P (Park). See “Shifting Into P (Park)”in the
Index of vehicle's owner manual for more information.
{WARNING:
It is dangerous to get out of the vehicle if the shift
lever is not fully in P (Park) with the parking brake
firmly set. The vehicle can roll.
Do not leave the vehicle when the engine is
running unless you have to. If you have left the
engine running, the vehicle can move suddenly.
You or others could be injured. To be sure the
vehicle will not move, even when you are on fairly
level ground, always set the parking brake and
move the shift lever to P (Park). See Shifting Into
Park in the Owner Manual. If you are pulling a
trailer, see Towing a Trailer on page 5‑8.
