■Selecting a driving mode
The following modes can be selected to suit driving conditions:
Eco drive mode
Suitable for improving the fuel economy,
because the torque corresponding to
the accelerator pedal depression
amount can be generated more
smoothly than it is in normal conditions
and the operation of the air conditioning
system (heating/cooling) will be mini-
mized.
When the “ECO MODE” switch is
pressed, the “ECO MODE” indicator
comes on in the meter.
Po w e r m o d e
Suitable when the vehicle needs to drive
powerfully or travels in mountainous
areas.
When the power mode switch is
pressed, the “PWR MODE” indicator
comes on in the meter.
■Using air conditioning in Eco drive mode
The Eco drive mode controls heating/cooling and fan speed operation to improve fuel
consumption. When you want to improve the effectiveness of the air conditioning sys-
tem, adjust the fan speed or cancel the Eco drive mode.
For more information, refer to the “Navigation System Owner’s Manual”.

22
■EV drive mode
In EV drive mode, the electric motor (traction motor), powered by the hybrid battery (trac-
tion battery), is used to drive the vehicle.
This mode allows you to drive in residential areas late at night, or in indoor parking lots etc.
without concern for noises and exhaust gas emissions.
Turns EV drive mode on/off
When EV drive mode is turned on, the
EV drive mode indicator will come on.
Pressing the switch when in EV drive
mode will return the vehicle to normal
driving (using the gasoline engine and
electric motor [traction motor]).
■Situations in which EV drive mode cannot be turned on
It may not be possible to turn EV drive mode on in the following situations. If it cannot be
turned on, a buzzer will sound and a message will be shown on the multi-information dis-
play.
• Vehicle speed is about 19mph (30km/h) or more.
• The hybrid battery (traction battery) is low.
In general, the remaining battery level indicated in the “Energy Monitor” display is level 3
or lower.
• The temperature of the hybrid system is high.
The vehicle has been left in the sun, driven on a hill, driven at high speeds, etc.
• The temperature of the hybrid system is low.
The vehicle has been left in temperatures lower than about 32°F (0°C) for a long
period of time etc.
• The gasoline engine is warming up.
