Hybrid Features

High Voltage 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 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 Gauge

United States

Canada

This gauge 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 gauge

will result in the best system

efficiency and fuel economy.

See Fuel Economy Gauge on

page 5‑4.

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 Trailer

Towing on page 9‑9 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 5‑3 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.

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.

For more information on Auto Stop,

Auto Start, and EV Mode, see

Starting the Vehicle on page 9‑2.

1-4 In Brief

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 on

page 9‑8.

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 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 if the hybrid

battery needs service. See Battery

on page 10‑12.

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 10‑2.
