switch while driving except in an emer-
gency. Turning the hybrid system off
while driving will not cause loss of
steering or braking control, however,
power assist to the steering will be lost.
This will make it more difficult to steer
smoothly, so you should pull over and
stop the vehicle as soon as it is safe to
do so.
●If the power switch is operated while
the vehicle is running, a warning mes-
sage will be shown on the multi-infor-
mation display and a buzzer sounds.
●When restarting the hybrid system
after an emergency shutdown, press
the power switch.

●Do not leave the power switch in
ACCESSORY or ON mode for long
periods of time without the hybrid sys-
tem on.
●If “ACCESSORY” or “IGNITION
ON” is displayed on the meter, the
power switch is not off. Exit the vehicle
after turning the power switch off.
●Do not stop the hybrid system when
the shift lever is in a position other than
P. If the hybrid system is stopped in
another shift lever position, the power
switch will not be turned off but instead
be turned to ACCESSORY mode. If
the vehicle is left in ACCESSORY
mode, 12-volt battery discharge may
occur.

Driving
Turns EV drive mode on/off
When EV drive mode is turned on, the EV
drive mode indicator will come on. Press-
ing 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 can-
not be turned on
It may not be possible to turn EV drive
mode on in the following situations. If it can-
not be turned on, a buzzer will sound and a
message will be shown on the multi-infor- mation display.
●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.
●The hybrid battery (traction battery) is
low.
The remaining battery level indicated in
the energy monitor display is low.
(
P.81)
●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 dr ive mode when the
gasoline engine is cold
If the hybrid system is started while the gas-
oline engine is cold, the gasoline engine will
start automatically after a short period of
time in order to warm up. In this case, you
will become unable to switch to EV drive
mode.
After the hybrid system has started and the
“READY” indicator has illuminated, press
the EV drive mode switch before the gaso-
line engine starts to switch to EV drive
mode.
■Automatic cancelation of EV drive
mode
When driving in EV drive mode, the gaso-
line engine may automatically restart in the
following situations. When EV drive mode
is canceled, a buzzer will sound and the EV
drive mode indicator will flash and go off.
EV drive mode
In EV drive mode, electric power is
supplied by the hybrid battery
(traction battery), and only the
electric motor (traction motor) is
used to drive the vehicle.
This mode allows you to drive in res-
idential areas early in the morning
and late at night, or in indoor park-
ing lots etc. without concern for
noises and gas emissions.
However, when the vehicle proxim-
ity notification system is active, the
vehicle may produce sound.

1404-2. Driving procedures
●The hybrid battery (traction battery)
becomes low.
The remaining battery level indicated in
the energy monitor display is low.
( P.81)
●Vehicle speed is high.
●The accelerator pedal is depressed firmly
or the vehicle is on a hill etc.
When it is possible to inform the driver of
automatic cancelation in advance, a prior
notice screen will appear on the multi-infor-
mation display.
■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 [traction battery] level
and driving conditions.)
■Fuel economy
The hybrid system is designed to achieve
the best possible fuel economy during nor-
mal driving (using the gasoline engine and
electric motor [traction motor]). Driving in
EV drive mode more than necessary may
lower fuel economy.
■If “EV Mode Unavailable” is shown on
the multi-information display
The EV drive mode is not available. The rea-
son the EV drive mode is not available (the
vehicle is idling, batter y charge is low, vehi-
cle speed is higher than the EV drive mode
operating speed range or accelerator 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 automatically
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 range 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.
WARNING
■Caution while driving
When driving in EV drive mode, pay spe-
cial attention to the area around the vehi-
cle. Because there is no engine noise,
pedestrians, 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.

Shift the shift lever while pushing the shift release button on the shift knob.
Shift the shift lever normally.
When shifting the shift lever between P and D, make sure that the vehicle is completely
stopped and the brake pedal is depressed.
*: For the vehicle be able to be shifted from P, the brake pedal must be depressed before the shift release button is pushed. If the shift release button is pushed first, the shift lock
will not be released.
■Shift lock system
The shift lock system is a system to prevent
accidental operation of the shift lever in
starting.
The shift lever can be shifted from P only
when the power switch is in ON mode the
brake pedal is depressed and the shift
release button is pushed.■If the shift lever cannot be shifted from P
First, check whether the brake pedal is
being depressed.
If the shift lever cannot be shifted even
though the brake pedal is depressed and

1444-2. Driving procedures
The selected shift range, from D1 to D6,
will be displaye d in the meter.
■When the “-” paddle shift switch is oper-
ated with the shift le ver in the D position
The shift range is do wnshifted to a range
that enables engine br aking force that is
suitable to driv ing conditions.
■Automatic deactivation of shift range
selection in the D position
Shift range selection in the D position will
be deactivated in the following situations:
●The “+” paddle shift switch is held down
for a period of time
●When the vehicle comes to a stop
●If the accelerator pedal is depressed for
more than a certain period of time
●When the shift lever is shifted to a posi-
tion other than D
■Downshifting restriction warning
buzzer
To help ensure safety and driving perfor-
mance, downshifting operation may some-
times be restricted. In some circumstances,
downshifting may not be possible even
when the shift lever or paddle shift switch is
operated. (A buzzer will sound twice.)
To enter S mode, shift the shift lever to
S. Shift ranges can be selected by
operating the shift lever or paddle shift
switches, allowing you to drive in the
shift range of your choosing. 1
Upshifting
2 Downshifting
The selected shift range, from S1 to S6, will
be displayed in the meter.
The initial shift range in S mode is set
automatically to S5 or S4 according to
vehicle’s speed.
■Shift ranges and their functions
You can choose from 6 levels of
accelerating force and engine brak-
ing force.
A lower shift range will provide
greater accelerating force and
engine braking force than a higher
shift range, and the engine revolu-
tions will also increase.
If you accelerate while in ranges 1 to
4, the shift range may automatically
increase in accordance with the
vehicle’s speed.
■S mode
●When the shift range is S4 or lower, hold-
ing the shift lever toward “+” sets the shift
range to S6.
●To prevent the engine from over-revving,
upshifting may automatically occur.
