actual item.
Hybrid system precautions
Take care when handling the hybrid system, as it is a high volt-
age system (about 650 V at maximum) as well as contains parts
that become extremely hot when the hybrid system is operating.
Obey the warning labels attached to the vehicle.

3386-1. Using the air conditioning system and defogger
CAMRY_HV_U (OM33C35U)
nOperation of the air conditioning system in Eco drive mode
In Eco drive mode, the air conditioning system is controlled as follows to pri-
oritize fuel efficiency:
lEngine speed and compressor operation controlled to restrict heating/cool-
ing capacity
l Fan speed restricted when automatic mode is selected
To improve air conditioning performance, perform the following operations:
l Adjust the fan speed
l Turn off Eco drive mode
n Using automatic mode
Fan speed is adjusted automatically according to the temperature setting and
the ambient conditions.
Therefore, the fan may stop for a while until warm or cool air is ready to flow
immediately after is pressed.
n Fogging up of the windows
lThe windows will easily fog up when the humidity in the vehicle is high.
Turning on will dehumidify the air from the outlets and defog the wind-
shield effectively.
l If you turn off, the windows may fog up more easily.
l The windows may fog up if the recirculated air mode is used.
n Windshield fog detection function
When automatic mode is set, the humidity sensor (P. 340) detects fog on
the windshield and controls the air conditioning system to prevent fog.
n Outside/recirculated air mode
lWhen driving on dusty roads such as tunnels or in heavy traffic, set the out-
side/recirculated air mode button to recirculated air mode. This is effective in
preventing outside air from entering the vehicle interior. During cooling oper-
ation, setting the recirculated air mode will also cool the vehicle interior
effectively.
l Outside/recirculated air mode may automatically switch depending on the
temperature setting or the inside temperature.
n When the outside temperature exceeds 75°F (24°C) and the air condition-
ing system is on
lIn order to reduce the air conditioning power consumption, the air condition-
ing system may switch to recirculated air mode automatically. This may also
reduce fuel consumption.
l Recirculated air mode is selected as a default mode when the power switch
is turned to ON mode.
l It is possible to switch to outside air mode at any time by pressing .
