●The windshield defogger is in use.
●When the shift position is in M.
■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 in order to warm up. In
this case, you will become unable to switch to EV drive mode.
To prevent gasoline engine warm up in order to reduce noises, start the hybrid sys-
tem without starting the gasoline engine, pressing the power switch with fully depressing the brake pedal and pressing
the EV drive mode switch.
■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 (LC500h)
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.

■Possible driving distance when driving in
EV drive mode
EV drive mode’s possible driving distance
ranges from a few hundred meters to approximately 1 km (0.6 mile). 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, battery 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,

other positions
 While depressing the brake pedal
firmly, operate the shift lever. If the
shift lever is operated without
depressing the brake pedal, the
buzzer will sound and the shifting
operation will be disabled.
 When selecting the shift position,
make sure that the shift position has
been changed to the desired posi-
tion by checking the shift position
indicator provided on the instru-
ment cluster.
 The shift position cannot be
changed from P to M directly.
■Automatic P position selection function
In the following situations, the shift position is automatically changed to P.
●When pressing the engine switch with the vehicle stopped while the engine switch is
in IGNITION ON mode and the shift position is in a positi on other than P (after the shift position has changed to P, the
engine switch will turn off)*
●When the vehicle is stopped after the engine has been stopped in an emer-gency while driving
●When voltage of the 12-volt battery drops while the shift position is in a posi-
tion other than P
*: When the engine switch is pressed while
driving at extremely slow speeds, such as
immediately before stopping the vehicle,
the shift position may automatically
change to P. Make sure that the vehicle is
completely stopped before pressing the
engine switch.
■If the shift position cannot be shifted
from P
There is a possibility that the 12-volt battery
is discharged. Check the 12-volt battery in this situation. ( P.392)
WARNING
■P position switch
●Do not press the P position switch
while the vehicle is moving. If the P position switch is pressed when driving at very low speeds (for exam-
ple, directly before stopping the vehi- cle), the vehicle may stop suddenly when the shift position switches to P,
which could lead to an accident.
●In order to prevent the shift position from accidentally being changed, do not touch the P position switch when
not using them.
NOTICE
■Notes regarding shift lever and P position switch operation
Avoid repeatedly operating the shift lever and P position switch in quick suc-cession.

Snow mode can be selected to suit the
conditions when driving on slippery
road surfaces, such as on snow.
Turn the switch backward.
The snow mode indicator comes on.
Turn the switch backward again to
return to normal mode.
■Snow mode automatic deactivation
Snow mode is automatically deactivated if the engine switch is tu rned off after driving
in snow mode.
To drive using temporary shift range
selection, operate the “-” or “+” paddle
shift switch.
When the “-” paddle shift switch is
operated, the shift range switches to a
range that enables engine braking
force that is suitable to driving condi-
tions. When the “+” paddle shift switch
is operated, the shift range switches to
a range that is one range higher than
the current range.
Changing the shift range allows
restriction of the highest gear, prevent-
ing unnecessary upshifting and
enabling the level of engine braking
force to be selected.
1 Upshifting
2 Downshifting
The selected shift range, from D1 to D10,
will be displayed in the meter.
To return to normal D position driving, the
“+” paddle shift switch must be held down
for a period of time.
A lower shift range will provide greater
engine braking forces than a higher shift
range.
