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.
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.

Fuel Economy Gage
United States Canada
This gage indicates fuel efficiency. To obtain the best
fuel efficiency, operate the vehicle so that the indicator
is in the high efficiency band.
Modifying both braking and acceleration behavior to
keep the indicator in the center of the gage will result
in the best system efficiency and fuel economy.
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 5‑2 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.
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.
1-3

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.
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 6‑17.
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.

Folding Rear Seat
Notice: Folding a rear seat with the safety belts
still fastened may cause damage to the seat or the
safety belts. Always unbuckle the safety belts and
return them to their normal stowed position before
folding a rear seat.
Make sure that nothing is on the seat.
To fold the seat, slowly pull the seat cushion up.
To return the seat to the normal seating position, slowly
pull the seat cushion down.
{WARNING:
A safety belt that is improperly routed, not
properly attached, or twisted will not provide the
protection needed in a crash. The person wearing
the belt could be seriously injured. After raising
the rear seatback, always check to be sure that
the safety belts are properly routed and attached,
and are not twisted.
Restraint System Check
Replacing Restraint System Parts
After a Crash
If an airbag inflates or the vehicle has been in a crash,
the vehicle's sensing system may command the
automatic hybrid battery disconnect to open. The
battery will disconnect. The hybrid battery will be off and
the vehicle will not start. The airbag readiness light and/
or SERVICE HYBRID SYSTEM warning message may
come on in the driver information center. See “Airbag
Readiness Light”in the owner manual and Driver
Information Center (DIC)
on page 4‑11 for more
information.
To operate the vehicle, the automatic hybrid battery
disconnect must be serviced by a qualified service
technician and sensing system parts will need to be
replaced. Have the vehicle serviced right away.
