Interior features
HIGHLANDER_HV_U■
Fogging up of the windows
●The 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.
● If you turn off, the windows may fog up more easily.
● The windows may fog up if the recirculated air mode is used.
■ Windshield fog detection function
When automatic mode is set, the humidity sensor (P. 446) detects fog on
the windshield and controls the air conditioning system to prev ent fog.
■ Outside/recirculated air mode
●When driving on dusty roads such as tunnels or in heavy traffic, set the out-
side/recirculated air mode button to the recirculated air mode. This is effec-
tive in preventing outside air from entering the vehicle interi or. During
cooling operation, setting the recirculated air mode will also cool the vehicle
interior effectively.
● Outside/recirculated air mode may automatically switch dependin g on the
temperature setting or the inside temperature.
■ When the outside temperature exceeds 75°F (24°C) and the air co ndition-
ing system is on
● In 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.
● Recirculated air mode is selected as a default mode when the power switch
is turned to ON mode.
● It is possible to switch to outside air mode at any time by pre ssing .
■ Ventilation and air conditioning odors
●To let fresh air in, set the air conditioning system to the out side air mode.
● During use, various odors from inside and outside the vehicle m ay enter into
and accumulate in the air conditioning system. This may then ca use odor to
be emitted from the vents.
● To reduce potential odors from occurring:
• It is recommended that the air conditioning system be set to o utside air
mode prior to turning the vehicle off.
• The start timing of the blower may be delayed for a short peri od of time
immediately after the air conditioning system is started in aut omatic
mode.

Maintenance and care
HIGHLANDER_HV_U
WARNING
The engine compartment contains many mechanisms and fluids that may
move suddenly, become hot, or become electrically energized. To avoid death
or serious injury, observe the following precautions.
■When working on the engine compartment
● Make sure that the “ACCESSORY” or “IGNITION ON” on the multi-in for-
mation display and the “READY” indicator are both off.
● Keep hands, clothing and tools away from the moving fans and en gine
drive belt.
● Be careful not to touch the engine, power control unit, radiator, exhaust
manifold, etc. right after driving as they may be hot. Oil and other fluids
may also be hot.
● Do not leave anything that may burn easily, such as paper and r ags, in the
engine compartment.
● Do not smoke, cause sparks or expose an open flame to fuel. Fuel fumes
are flammable.
■ When working near the electric cooling fans or radiator grille
Be sure the power switch is off.
With the power switch in ON mode, the electric cooling fans may automati-
cally start to run if the air conditioning is on and/or the coolant temperature
is high. ( P. 514)
■ Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc.
from getting in your eyes.
NOTICE
■If you remove the air cleaner filter
Driving with the air cleaner filter removed may cause excessive engine wear
due to dirt in the air.
