for more than 20 minutes or IGNITION
ON mode (the engine is not running) for
more than an hour with the shift position in
P, the engine switch will automatically turn
off. However, this fu nction cannot entirely
prevent the 12-volt battery discharge. Do

4Check that the “READY” indicator
is illuminated.
If the “READY” indicator changes from a
flashing light to a solid light and the buzzer
sounds, the hybrid system is starting nor-
mally.
The vehicle will not move when the
“READY” indicator is off.
The vehicle can move when the “READY”
indicator is on even if the engine is
stopped.(The gasoline engine starts or
stops automatically in accordance with the
state of the vehicle.)
■Power switch illumination
According to the situation, the power
switch illumination operates as follows.
●When a door is opened, or the power
switch mode is changed from ACCES-
SORY or ON mode to off, the power
switch illumination slowly blinks.
●When depressing the brake pedal with
carrying the electric key on your person,
the power switch illu mination rapidly

■When the ambient temperature is low,
such as during winter driving conditions
●When starting the hybrid system, the
flashing time of the “READY” indicator
may be long. Leave the ve hicle as it is until
the “READY” indicator is steady on, as
steady means the vehicle is able to move.
●When the hybrid battery (traction bat-
tery) is extremely cold (below approxi-
mately -22°F [-30°C]) under the
influence of the outside temperature, it
may not be possible to start the hybrid
system. In this case, try to start the hybrid
system again after the temperature of the
hybrid battery increases due to the out-
side temperature increase etc.

5 Temporary operation
When “AUTO” is se lected, the sensor
sensitivity can be adjusted by turning
the switch ring.
6 Increases the sensitivity
7 Decreases the sensitivity
8 Washer/wiper dual operation
The wipers will automatically operate a
couple of times afte r the washer squirts.
(After operating severa l times, the wipers
operate once more time after a short delay
to prevent dripping. However, the dripping
prevention does not operate while the
vehicle is moving.)
■The windshield wiper and washer can be
operated when
The engine switch is in IGNITION ON mode .
■Raindrop sensor
●The raindrop sensor judges the amount
of raindrops.
An optical sensor is adopted. It may not

strikes the windshield, or if bugs etc. are
present on the windshield.
●If the wiper is turned to “AUTO” position
while the engine switch is
in IGNITION ON mode ,
the wipers will operat e once to show that
“AUTO” mode is activated.
●If the temperature of the raindrop sensor
is 185°F (85°C) or higher, or -22°F (-
30°C) or lower, automatic operation
may not occur. In this case, operate the
wipers in any mode other than “AUTO”.
■If no windshield washer fluid sprays
