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.
Performance and Maintenance
Tire Sealant and Compressor Kit
This vehicle has a tire sealant and compressor kit which
can be used to seal small punctures in the tread area of
the tire.
See “Tire Sealant and Compressor Kit”for complete
operating information.
