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 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

page 4‑4

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.

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.

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. 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 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. 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.

3-14

Keep your foot firmly on the brake pedal until you are ready for the vehicle to move.

page 4‑4

for more information.

Auto Start

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.
