Interior features
SEQUOIA_OM_USA_OM0C047U
■Using automatic mode
Fan speed is adjusted automatically according to the temperatur e 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.
■ 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.
■ When driving on dusty roads
Close all windows. If dust thrown up by the vehicle is still drawn into the vehi-
cle after closing the windows, it is recommended that the air intake mode be
set to outside air mode and the fan speed to any setting except off.
■ Outside/recirculated air mode
●Setting to the recirculated air mode temporarily is recommended in prevent-
ing dirty air from entering the vehicle interior and helping to cool the vehicle
when the outside air temperature is high.
● Outside/recirculated air mode may automatically switch dependin g on the
temperature setting, outside temperature, pressure, engine cool ant tem-
perature or inside temperature.
■ When the outside temperature exceeds 75 °F (24 °C) and the air condi-
tioning 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 en gine switch
is turned to ON.
● It is possible to switch to outside air mode at any time by pre ssing
.
■When the outside temperature f alls to nearly 32 °F (0 °C)
The dehumidification function may not operate even when is pre ssed.

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
● Keep hands, clothing and tools away from the moving fan and engine
drive belt.
● Be careful not to touch the engine, 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 or t he bat-
tery. Fuel and battery fumes are flammable.
● Be extremely cautious when working on the battery. It contains poisonous
and corrosive sulfuric acid.
■ When working near the electric cooling fan or radiator grille
Be sure the engine switch is off. With the engine switch on, th e electric cool-
ing fans may automatically start to run if the air conditioning is on and/or the
coolant temperature is high. ( P. 422)

the pressure.
If you add too much air, press the center of the valve to defla te.
After completing the tire inflation pressure measurement and
adjustment, apply soapy water to the valve and check for leakage.
Put the tire valve cap back on.
■Tire inflation pressure check interval

a month.
Do not forget to check the spare.
■Effects of incorrect tire inflation pressure
Driving with incorrec t tire inflation pressure may result in th e following:
●Reduced fuel economy
●Reduced driving comfort and poor handling
●Reduced tire life due to wear
●Reduced safety
