may lead to death or a serious
health hazard.
●If the vehicle is in a poorly venti-
lated area or a closed area,
such as a garage, stop the
hybrid system.
●Do not leave the vehicle with
the hybrid system operating for
a long time. If such a situation
cannot be avoided, park the
vehicle in an open space and
ensure that exhaust fumes do
not enter the vehicle interior.
●Do not leave the hybrid system
operating in an area with snow
build-up, or where it is snowing.
If snowbanks build up around

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 po ssible to turn EV
drive mode on in t he following situa-
tions. If it cannot be turned on, a buzzer will sound
and a message
will be shown on the multi-informa-
tion display.
●The temperature of the hybrid sys-
tem is high.
The vehicle has been left in the
sun, driven on a hill, driven at high
speeds, etc.
●The temperature of the hybrid sys-
tem is low.
The vehicle has been left in tem-
peratures lower than about 32°F
(0°C ) for a long period of time etc.
●The gasoline engine is warming
up.
●The hybrid battery (traction bat-
tery) is low.
The remaining batt ery level indi-
cated in the energy monitor dis-
play is low. ( P. 1 1 2 )
●Vehicle speed is high.
●The accelerator pedal is
depressed firmly or the vehicle is
on a hill etc.
●The windshield defogger is in use.
■Switching to EV drive mode
when the gasoline engine is
cold
If the hybrid system is started while
the gasoline engine is cold, the gas-
oline engine will st art automatically
after a short period of time in order
to warm up.I n this case, you will
become unable to switch to EV drive
mode.
After the hybrid s ystem has started
and the “READY” indicator has illu-
minated, press the EV drive mode
switch before the gasoline engine
starts to switch to EV drive mode.
■Automatic cancelation of EV
drive mode
When driving in EV drive mode, the
gasoline engine may start automati-
cally and the vehic le may be driven
by the gasoline engine and electric
motor (traction motor) in the follow-
ing situations. When EV drive mode
is canceled, a buzze r will sound, the
EV drive mode
In EV drive mode, electric
power is supplied by the
hybrid battery (traction bat-
tery), and only the electric
motor (traction motor) is
used to drive the vehicle.
This mode allows you to
drive in residential areas
early in the morning and
late at night, or in indoor
parking lots etc. without
concern for noises and gas
emissions.

■Possible driving distance when
driving in EV drive mode
EV drive mode’s possible driving
distance ranges from a few hundred
meters to approximately 0.6 mile (1
km). However, depending on vehicle
conditions, there are situations
when EV drive mode cannot be
used.
(The distance that is possible
depends on the hybrid battery [trac-
tion battery] level and driving condi-
tions.)
■Fuel economy
The hybrid system is designed to
achieve the best possible fuel econ-
omy during normal driving (using
the gasoline engi ne and electric
motor [traction motor]). Driving in
EV drive mode more than neces-
sary may lower fuel economy.
■If “EV Mode Unavailable” is
shown on the multi-information
display
The EV drive mode is not available.
The reason the EV drive mode is
not available (the v ehicle is idling,
battery charge is low, vehicle speed
is higher than the EV drive mode
operating speed range or accelera-
tor pedal is depressed too much)
may be displayed. Use the EV drive
mode when it becomes available.
■If “EV Mode Deactivated” is
shown on the multi-information
display
The EV drive mode has been auto- matically canceled. The reason the
EV drive mode is not available (the
battery charge is low, vehicle speed
is higher than the EV drive mode
operating speed r
ange or accelera-
tor pedal is depressed too much)
may be displayed. Drive the vehicle
for a while before attempting to turn
on the EV drive mode again.

■Caution while driving
When driving in EV drive mode,
pay special attention to the area
around the vehicle. Because
there is no engine noise, pedestri-
ans, people riding bicycles or
other people and vehicles in the
area may not be aware of the
vehicle starting off or approaching
them, so take extra care while
driving. Therefore, take extra care
while driving even if the vehicle
proximity notification system is
active.
