5-1. Using the air conditioning system and defogger
Interior features
windshield effectively.
●If you turn “A/C” off, the windows may fog up more easily.
●The windows may fog up if the recir-culated air mode is used.
■When driving on dusty roads
Close all windows. If dust thrown up by the vehicle is still drawn into the vehicle after closing the windows, it is recom-
mended 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 pre-
venting dirty air from entering the vehicle interior and helping to cool the vehicle when the outside air tempera-
ture is high.
●Outside/recirculated air mode may
automatically switch depending on the temperature setting or the inside tem-perature.
■Operation 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:• Engine speed and compressor opera-
tion controlled to restrict heating/cool- ing capacity• Fan speed restricted when automatic
mode is selected
●To improve air conditioning perfor-
mance, perform the following opera- tions:• Adjust the fan speed
• Turn off Eco drive mode ( P.330)
●Even when the drive mode is set to
Eco drive mode, the air conditioning eco mode can be turned off by press-ing the “FAST/ECO” switch. ( P.352)
■When the outside temperature falls
to nearly 0°C (32°F)
The dehumidification function may not operate even when “A/C” switch is
pressed.
■Ventilation and air conditioning
odors
●To let fresh air in, set the air condition-
ing 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 occur-
ring: • It is recommended that the air condi-tioning 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.
●When parking, the system automati-cally switches to outside air mode to encourage better air circulation
throughout the vehicle, helping to reduce odors that occur when starting the vehicle.
■Air conditioning filter

■Customization
Some functions can be customized. ( P.498)
WARNING
■To prevent the windshield from fogging up
Do not use the windshield defogger
switch during cool air operation in extremely humid weather. The differ-ence between the temperature of the
outside air and that of the windshield can cause the outer surface of the windshield to fog up, blocking your
vision.
■When the outside rear view mir-
ror defoggers are operating
Do not touch the outside rear view mirror surfaces, as they can become
very hot and burn you.

6-1. Maintenance and care
Maintenance and care
●Use a soft cloth dampened with an
approximately 5% solution of neutral detergent and water to clean the dirt off.
●Wipe the surface with a dry, soft cloth to remove any remaining moisture.
●To remove oily deposits, use alcohol wet wipes or a similar product.
WARNING
■When washing the vehicle
Do not apply water to the inside of the engine compartment. Doing so may
cause the electrical components, etc. to catch fire.
■When cleaning the windshield (vehicles with rain-sensing wind-shield wipers)
Set the wiper switch to off. If the wiper switch is in “AUTO”, the wipers may operate unexpectedly in the following
situations, and may result in hands being caught or other serious injuries and cause damage to the wiper
blades.
Off
AUTO
●When the upper part of the wind- shield where the raindrop sensor is
located is touched by hand
●When a wet rag or similar is held
close to the raindrop sensor
●If something bumps against the
windshield
●If you directly touch the raindrop sensor body or if something bumps into the raindrop sensor
■Precautions regarding the exhaust pipe
Exhaust gasses cause the exhaust pipe to become quite hot.When washing the vehicle, be careful
not to touch the pipe until it has cooled sufficiently, as touching a hot exhaust pipe can cause burns.
■Precaution regarding the rear bumper with Blind Spot Monitor
(if equipped)
If the paint of the rear bumper is chipped or scratched, the system may
malfunction. If this occurs, consult with any authorized Toyota retailer or Toyota authorized repairer, or any reli-
able repairer.
NOTICE
■To prevent paint deterioration and corrosion on the body and
components (aluminum wheels, etc.)
●Wash the vehicle immediately in the
following cases:
• After driving near the sea coast
• After driving on salted roads
• If coal tar or tree sap is present on the paint surface
• If dead insects, insect droppings or bird droppings are present on the paint surface
• After driving in an area contami- nated with soot, oily smoke, mine
dust, iron powder or chemical sub- stances
• If the vehicle becomes heavily soiled with dust or mud

6-2. Maintenance
Maintenance and care
request that a record of maintenance
be kept.
■Does your vehicle need repairs?
Be on the alert for changes in perfor- mance and sounds, and visual tip-offs
that indicate service is needed. Some important clues are:
●Engine misses (misfire), stumbling or pinging
●Appreciable loss of power
●Strange engine noises
●A fluid leak under the vehicle (How-ever, water dripping from the air con-
ditioning system after use is normal.)
●Change in exhaust sound (This may
indicate a dangerous carbon monox- ide leak. Drive with the windows open and have the exhaust system checked
immediately.)
●Flat-looking tires, excessive tire
squeal when cornering, uneven tire wear
●Vehicle pulls to one side when driven straight on a level road
●Strange noises related to suspension movement
●Loss of brake effectiveness, spongy feeling brake pedal, pedal almost touches the floor, vehicle pulls to one
side when braking
●Engine coolant temperature continu- ally higher than normal ( P.100, 95)
If you notice any of these clues, take
your vehicle to any authorized Toyota retailer or Toyota authorized repairer, or any reliable repairer as soon as possi-
ble. Your vehicle may need adjustment or repair.

Maintenance and care
WARNING
●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 flu-ids 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 or 12- volt battery. Fuel and 12-volt battery fumes are flammable.
●Be extremely cautious when work-ing on the 12-volt battery. It con-
tains poisonous and corrosive sulfuric acid.
●Take care because brake fluid can harm your hands or eyes and dam-age 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 fan or radiator grille
Be sure the power switch is OFF.
With the power switch in ON, the electric cooling fan may automatically start to run if the air conditioning is on
and/or the coolant temperature is high. ( P.393)
■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 fil- ter
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 refill- ing, it may indicate a serious problem.

The shape of the dipstick may differ
depending on the type of vehicle or engine.
6 Wipe the dipstick and reinsert it
fully.
■Checking the oil type and pre-
paring the item needed
Make sure to check the oil type and
prepare the items needed before
adding oil.
