unbraked TWR, trailer service
brakes are required.
 If the gross trailer weight is over
2000 lb. (907 kg), a sway control
device with sufficient capacity is
required.
Confirm that the gross trailer weight,
gross combination weight, gross vehi-
cle weight, gross axle weight and
tongue weight are all within the limits.

DrivingTurns 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.99)
●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 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, the EV
drive mode indicator will go off after flash-
ing, and a message is displayed on the
multi-information display.
●The hybrid battery (traction battery)
becomes low.
The remaining battery level indicated in
the “Energy Monitor” display is low.
(  P.99)
●Vehicle speed is high.
●The accelerator pedal is depressed firmly
or the vehicle is on a hill, etc.
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.
Operating instructions

1904-2. Driving procedures
■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-inform ation 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-inform ation 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 no
engine noise is made. As such, pedestri-
ans, people riding bicycles or other peo-
ple and vehicles in the surrounding area
may not be aware of the vehicle starting
off or approaching them. Therefore, take
extra care while driving even if the
Acoustic Vehicle Alerting System is
active.

ically set to S4 or S5 according to the vehi-
cle 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 speed.
■S mode
●When the shift range is S4 or lower, hold-
ing the shift lever towa rd “+” sets the shift
range to S6.
●Automatically selects a higher shift range
