Interior features
■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 interior. During
cooling operation, setting the recirculated air mode will also cool the vehicle
interior effectively.
● Outside/recirculated air mode may automatically switch depending on the
temperature setting or the inside temperature.
■ When the outside temperature is low
The dehumidification function may not operate even when is pressed.
■ Ventilation and air conditioning odors
● To let fresh air in, set the air conditioning 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 conditioni ng system is started in automatic
mode.
■ Air conditioning filter

■ Customization
Settings (e.g. air conditioning setting) can be changed.

Maintenance and care
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 and the
“READY” indicator are both off.
● Keep hands, clothing and tools away from the moving fan and engine
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 rags, in the
engine compartment.
● Do not smoke, cause sparks or expose an open flame to fuel. Fuel fumes
are flammable.
● Take care because brake fluid can harm your hands or eyes and damage
painted surfaces. If fluid gets on your hands or in your eyes, flush the
affected area with clean water immediately.
If you still experience discomfort, consult a doctor.
■ 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. 432)
■ 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.
■ If the fluid level is low or high
It is normal for the brake fluid level to go down slightly as the brake pads
wear or when the fluid level in the accumulator is high.
If the reservoir needs frequent refilling, it may indicate a serious problem.

The coolant level is satisfactory if it is between the “FULL” and “LOW”
lines on the reservoir when th e hybrid system is cold.
Engine coolant reservoir
Reservoir cap
“FULL” line
“LOW” line
If the level is on or below the
“LOW” line, add coolant up to
the “FULL” line.
WARNING
■ Used engine oil
● Used engine oil contains potentially harmful contaminants which may
cause skin disorders such as inflammation and skin cancer, so care
should be taken to avoid prolonged and repeated contact. To remove used
engine oil from your skin, wash thoroughly with soap and water.
● Dispose of used oil and filters only in a safe and acceptable manner. Do
not dispose of used oil and filters in household trash, in sewers or onto the
ground.
Call any authorized Toyota dealer or repairer, or another duly qualified and
equipped professional, service station or auto parts store for information
concerning recycling or disposal.
● Do not leave used engine oil within the reach of children.
NOTICE
■To prevent serious engine damage
Check the oil level on a regular basis.
■ When replacing the engine oil
● Be careful not to spill engine oil on the vehicle components.
● Avoid overfilling, or the engine could be damaged.
● Check the oil level on the dipstick every time you refill the vehicle.
● Be sure the engine oil filler cap is properly tightened.

■Replacement method
Remove the air conditioning fil-
ter and replace it with a new
one.
The “ UP” marks shown on the
filter should be pointing up.
■ Checking interval
Inspect and replace the air conditioning filter according to the maintenance
schedule. In dusty areas or areas with heavy traffic flow, early replacement
may be required. (For scheduled maintenance information, please refer to the
“Toyota Service Booklet” or “Toyota Warranty Booklet”.)
■ If air flow from the vents decreases dramatically
The filter may be clogged. Check the filter and replace if necessary.
NOTICE
■ When using the air conditioning system
Make sure that a filter is always installed.
Using the air conditioning system without a filter may cause damage to the
system.

When trouble arises
■If “Hybrid battery low. Shift out of N to recharge.” is displayed
Message is displayed when the remaining charge for the hybrid
battery (traction battery) is low.
As the hybrid battery (traction battery) cannot be charged when the
shift position is in N, when stopped for long periods of time change
the shift position to P.
■If “Hybrid system overheated. Reduced output power.” is dis-
played
This message may be displayed wh en driving under severe operat-
ing conditions.
(For example, when driving up a long steep hill.)
Handling method: P. 5 4 4
■If “Maintenance required for hybrid battery cooling parts at
your dealer.” is displayed
The filter may be clogged, the ai r intake vent may be blocked or
there may be a gap in the duct. Have maintenance performed on
the hybrid battery (traction batt ery) cooling component at any
authorized Toyota dealer or repairer, or another duly qualified and
equipped professional.
