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 3-4 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.

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. Some of the vehicle conditions that

may cause the engine to Auto Start are:

• The hood is opened.

• The gear selector is in M (Manual Mode) or

R (Reverse).

• The hybrid battery state of charge is too low.

• The hybrid battery voltage, temperature or power

limits are exceeded.

• The engine is not at operating temperature.

• Acceleration demands require the use of the engine.

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.

If increased acceleration is required, or the vehicle

reaches approximately 30 mph (40 km/h), the engine

will start automatically. The engine shuts off at speeds

below 25 mph (40 km/h) 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.
