main display.
■ Auto power off function
If the vehicle is left in ACCESSORY mode for more than 20 minutes or ON
mode (the hybrid system is not operating) for more than an hour with the shift
position in P, the power switch will automatically turn off. However, this func-
tion cannot entirely prevent the 12-volt battery discharge. Do not leave the
vehicle with the power switch in ACCESSORY or ON mode for long periods
of time when the hybrid system is not operating.
■ Sounds and vibrations specific to a hybrid vehicle
→P. 8 8
■ Electronic key battery depletion
→P. 264
■ When the ambient temperature is low, such as during winter driving con-
ditions
● When starting the hybrid system, the flashing time of the “READY” indicator
may be long. Leave the vehicle as it is until the “READY” indicator is steady
on, as steady means the vehicle is able to move.
● When the hybrid battery (traction battery) 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 outside temperature increase etc.

■Meter display
When the power switch is turned off, each display will turn off as follows.
●The shift position indicator will turn off after approximately 2 seconds.
● The multi-information display, clock, etc. will turn off after approximately 30
seconds.
(Each display will also turn off immediately if a door is locked before 30 sec-
onds has elapsed.)
■ If the smart key system has been deactivated in a customized setting
→P. 691
WARNING
■When starting the hybrid system
Always start the hybrid system while sitting in the driver’s seat. Do not
depress the accelerator pedal while starting the hybrid system under any
circumstances.
Doing so may cause an accident resulting in death or serious injury.
■ Stopping the hybrid system in an emergency
● If you want to stop the hybrid system in an emergency while driving the
vehicle, press and hold the power switch for more than 2 seconds, or
press it briefly 3 times or more in succession. ( →P. 645)
However, do not touch the power 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
message will be shown on the multi-information display and a buzzer
sounds.
● When restarting the hybrid system after an emergency shutdown while
driving, press the power switch. When restarting the hybrid system after
stopping the vehicle, change the shift position to P and then press the
power switch.

5-3. Operating the lights and wipers
■The windshield wipers and washer can be operated when
The power switch is in ON mode.
■ Dripping prevention wiper sweep (vehicles with rain-sensing windshield
wipers)
After washing and wiping operation several times, the wipers operate one
more time after a short delay to prevent dripping. However, this function will
not operate while driving.
■ Effects of vehicle speed on wiper operation (vehicles with rain-sensing
windshield wipers)
Vehicle speed affects the Intermittent wiper interval.
■ Raindrop sensor (vehicles with ra in-sensing windshield wipers)
● If the wiper switch is turned to the “AUTO” position while the power switch is
in ON mode, the wipers will operate once to show that AUTO mode is acti-
vated.
● If the wiper sensitivity is adjusted to higher, the wiper may operate once to
indicate the change of sensitivity.
● If the temperature of the raindrop sensor is 185 °F (85 °C) or higher, or 14° F
(-10° C) or lower, automatic operation may not occur. In this case, operate
the wipers in any mode other than AUTO mode.
■ If no windshield washer fluid sprays
Check that the washer nozzles are not blocked, if there is washer fluid in the
washer fluid tank.
■ Customization
Settings of AUTO mode operation can be changed.
(Customizable features: →P. 732)
●
The raindrop sensor judges the amount
of raindrops.
An optical sensor is adopted. It may not
operate properly when sunlight from the
rising or setting of the sun intermittently
strikes the windshield, or if bugs, etc.
are present on the windshield.

5-5. Using the driving support systems
• If a vehicle ahead is carrying a load which protrudes past its rear bumper
• If a vehicle ahead is irregularly shaped, such as a tractor or side car
• If the sun or other light is shining directly on a vehicle ahead
• If a vehicle cuts in front of your vehicle or emerges from beside a vehicle
• If a vehicle ahead makes an abrupt maneuver (such as sudden swerving,
acceleration or deceleration)
• When suddenly cutting behind a preceding vehicle
• When driving in inclement weather such as heavy rain, fog, snow or a sandstorm
• When the vehicle is hit by water, snow, dust, etc. from a vehicle ahead
• When driving through steam or smoke
• When driving in a place where the surrounding brightness changes sud-
denly, such as at the entrance or exit of a tunnel
• When a very bright light, such as the sun or the headlights of oncoming traffic, shines directly into the camera sensor
• When the surrounding area is dim, such as at dawn or dusk, or while at night or in a tunnel
• After the hybrid system has started the vehicle has not been driven for a
certain amount of time
• While making a left/right turn and for a few seconds after making a left/ right turn
• While driving on a curve and for a few seconds after driving on a curve

Driving
Example of constant speed cruising
When there are no vehicles ahead
The vehicle travels at the speed set by the driver. The desired vehicle-to-
vehicle distance can also be set by operating the vehicle-to-vehicle dis-
tance button.
Example of deceleration cruising and follow-up cruising
When a preceding vehicle driving slower than the set speed
appears
When a vehicle is detected running ahead of you, the system automatically
decelerates your vehicle. When a greater reduction in vehicle speed is
necessary, the system applies the brakes (the stop lights will come on at
this time). The system will respond to changes in the speed of the vehicle
ahead in order to maintain the vehicle-to-vehicle distance set by the driver.
Approach warning warns you when the system cannot decelerate suffi-
ciently to prevent your vehicle from closing in on the vehicle ahead.
When the vehicle ahead of you stops, your vehicle will also stop (vehicle is
stopped by system control). After the vehicle ahead starts off, pushing the
cruise control lever up or depressing the accelerator pedal will resume fol-
low-up cruising.
Example of acceleration
When there are no longer any preceding vehicles driving slower
than the set speed
The system accelerates until the set speed is reached. The system then
returns to constant speed cruising.
