■Obstacles not detected
The sensor cannot detect plastic obstacles such as traffic cones. There may
also be occasions when the sensor cannot detect pedestrians, animals,
bicycles, motorcycles, trees, or snowdrifts.
■ Situations in which the pre-collis ion system does not function properly
The system may not function effectively in situations such as the following:
● On roads with sharp bends or uneven surfaces
● If a vehicle suddenly moves in front of your vehicle, such as at an inter-
section
● If a vehicle suddenly cuts in front of your vehicle, such as when overtak-
ing
● In inclement weather such as heavy rain, fog, snow or sand storms
● When your vehicle is skidding with the VSC system off
● When an extreme change in vehicle height occurs
● When the axis of the radar is out of adjustment
■ Automatic cancelation of the pre-collision system
When a malfunction occurs due to sensor contamination, etc. that results in
the sensors being unable to detect obstacles, the pre-collision system will be
automatically disabled. In this case, the system will not activate even if there
is a collision possibility.
■ When there is a malfunction in th e system, or if the system is tempo-
rarily unusable
Warning lights and/or warning messages will turn on or flash. ( P. 506, 520)

Solar Ventilation System
: If equipped
The Solar Ventilation System uses energy provided by solar panel
built into the roof to operate a fa n contained within the air condition-
ing system, allowing ventilation of the vehicle interior when the vehi-
cle is parked in direct sunlight.
■ Activating the Solar Ventilation System
With the “POWER” switch in
ON mode, turn on the ventila-
tion switch.
Off
On
Turn the “POWER” switch off.
After approximately 1 minute, outside air mode will be selected
and the air vents will be put into upper body mode.
After approximately 10 minutes, the ventilation operation will
commence.
The ventilation operation will be canceled if the “POWER”
switch is turned to ON mode or the ventilation switch is turned
off.

■Operating conditions
The Solar Ventilation System may not operate under the following circum-
stances due to a lack of power from the solar panel:
●Low amount of sunlight
● Ever when a part of the solar panel is cast by a shadow.
● Ever when a part of the solar panel is covered by fallen leaves or dirt.
● The solar panel is not at a high temperature.
■ Before using the Solar Ventilation System
Remove dirt or fallen leaves from the solar panel in order to ensure sufficient
electrical output.
■ Efficient use of the So lar Ventilation System
Efficient control of temperature increase can be achieved by using the sys-
tem in conjunction with the Remote Air Conditioning System. ( P. 348)
■ When using the Sola r Ventilation System
● Make sure that the “POWER” switch is in ON mode when turning the
ventilation switch on. If the ventilation switch is turned on while the
“POWER” switch is OFF, the air mode and the status of the air vents will
remain unchanged.
● If the Solar Ventilation System is not needed, be sure to turn the ventila-
tion switch off.
Dirty air and exhaust fumes from other vehicles may be drawn from out-
side. Also, use in winter may cause heated interior air to leave the vehi-
cle, thus leading to a drop in temperature.
■ Sounds when using the Solar Ventilation System
If the amount of sunlight is insufficient, you may hear a sound coming from
the air conditioning system. This is the sound of a control function to pre-
serve the fan and does not indicate a malfunction.

■Using the Remote Air Conditioning System effectively
Efficiency can be increased by using the system in conjunction with the
Solar Ventilation System. ( P. 345)
■ When leaving the vehicle
●Check that the headlights are switched to either off or “AUTO”.
● Check that the wiper switch is turned off.
● Check that all windows are closed.
■ Remote Air Conditioning System automatic shut-off
The system will automatically shut off under the following conditions:
●About 3 minutes have passed since operation began
● Any one of the operating conditions is not met
The system may also shut off if the charge level of the hybrid battery (trac-
tion battery) drops to low. ( P. 44)
■ Conditions aff ecting operation
The system may not start in the following situations:
● The charge level of the hybrid battery (traction battery) is low ( P. 44)
● The air conditioning temperature is set at a high level or outside tempera-
ture is low
● When the vehicle has been left parked for a number of days
● When the hybrid system is cool (for example, after being left for a long
time in low temperatures)
