Interior features
■Outside temperature display
■ When the outside temperature is low
The dehumidification function may not operate even when is pressed.
■ Operation of the air conditio ning system in Eco drive mode
● In the Eco drive mode, the air conditioning system is controlled as follows to
prioritize fuel efficiency
• Engine speed and compressor operation controlled to restrict heating/
cooling capacity
• Fan speed restricted when automatic mode is selected
● To improve air conditioning performance, perform the following operations
• Adjust the fan speed
• Turn off Eco drive mode
• Customize the air conditioning control of Eco drive mode. ( P. 565)
■ Ventilation and air conditioning odors
●To let fresh air in, set the air condi tioning system to the outside air mode.
● During use, various odors from inside and outside the vehicle may enter into
and accumulate in the air conditioning system. This may then cause odor to
be emitted from the vents.
● To reduce potential odors from occurring:
• It is recommended that the air conditioning system be set to outside air
mode prior to turning the vehicle off.
• The start timing of the blower may be delayed for a short period of time immediately after the air conditioning system is started in automatic
mode.
■ Air conditioning filter
P. 445
■ Customization
Settings (e.g. A/C auto switching operation) can be changed.
(Customizable features: P. 559)
In the following situations, the correct out-
side temperature may not be displayed, or
the display may take longer than normal
to change.
●
When stopped, or driving at low speeds
(less than 16 mph [25 km/h])

7-3. Do-it-yourself maintenance
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 “POWER ON” on the multi-information display or the
smart key system indicator, and the “READY” indicator are both off.
● Keep hands, clothing and tools away from the moving fan.
● 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 rags, 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 conditioni ng is on and/or the coolant temperature
is high. ( P. 421)
■ 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.
