Range Selection Mode
The Range Selection Mode switch is on the shift lever.
To enable the Range Selection feature:
1. Move the 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.
2. Press the plus/minus buttons on the steering column shift lever to select the desired range of gears for current driving conditions.
Cruise control can be used while the vehicle is in Range Selection Mode.
See Manual Mode on page 97.

Hybrid Features

Fuel Economy Gauge

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.
Metric
English
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 54.

Automatic Engine Start/ Stop Feature

Start the engine as you would any other engine. See Starting the Enginein 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 98 for more information.

In Brief 1-3
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.
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 53 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 92.

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 ensure 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 98.

1-4 In Brief

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 1010.

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 101.

Airbag System

Replacing Airbag 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. When the battery disconnect is open, 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 (DIC). See Airbag Readiness Lightin the owner manual and Driver Information Center (DIC) on page 59 for more information.
To operate the vehicle, the automatic hybrid battery disconnect must be reconnected by a qualified service technician and sensing system parts will need to be replaced. Have the vehicle serviced right away.

Tachometer

English Shown, Metric Similar
When the ignition is in ON/RUN, the tachometer indicates the vehicle status.
When pointing to AUTO STOP, the vehicle is on and can move. the engine could AUTO START at any time. when the indicator is OFF, the vehicle is off. when the engine is on, the tachometer will indicate the engine's revolutions per minute (rpm).
The tachometer may vary by several hundred rpm's, during AUTO STOP mode, when the engine is shutting off and restarting. A slight bump may be felt when the transmission is determining the most fuel efficient operating range.

Fuel Gauge

Metric
English
When the ignition is on, the fuel gauge shows approximately how much fuel is left in the fuel tank. An arrow on the fuel gauge indicates the side of the vehicle the fuel door is on. The gauge first indicates E (empty) before the vehicle is out of fuel, but the vehicle should be refueled as soon as possible.

5-4 Instruments and Controls
Listed are four situations that may occur with the fuel gauge, none of these indicate a problem:
.
At the gas station, the fuel pump shuts off before the gauge reads F (full).
.
It takes a little more or less fuel to fill up than the fuel gauge indicated. For example, the gauge may have indicated the tank was half full, but it actually took a little more or less than half the tank's capacity to fill the tank.
.
The gauge moves a little while turning a corner or while accelerating.
.
The gauge does not go back to E (empty) when the ignition is turned off.

Fuel Economy Gauge

Metric
English
This gauge is to assist in driving efficiently and may vary during normal operation.
the vehicle is being driven the most efficient when the gauge is kept in the middle.
The gauge moves to the left when braking and to the right when accelerating. When either are done aggressively, the efficiency is decreased.
