2765-1. Using the air conditioning system and defogger
AVALON_HV_U (OM41451U)■
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. 278) detects fog on
the windshield and controls the air conditioning system to prevent fog.
■ Outside/recirculated air mode
●When driving on dusty roads such as tunnels or in heavy traffic, set the out-
side/recirculated air mode to the recirculated air mode. This is effective in
preventing outside air from entering the vehicle interior. During cooling oper-
ation, setting the recirculated air mode will also cool the vehicle interior
effectively.
● Outside/recirculated air mode may automatically switch depending on the
temperature setting, outside temperature, pressure, engine coolant temper-
ature or inside temperature.
■ When the outside temperature exceeds 75°F (24°C) and the air condition-
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 pressing
.
■ When the outside temperature falls to nearly 32 F (0 C)
The dehumidification function may not operate even when is touched.
■ Air conditioning odors
●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.

Maintenance and care
AVALON_HV_U (OM41451U)■
Aluminum wheels
●Remove any dirt immediately by using a neutral detergent. Do not use hard
brushes or abrasive cleaners. Do not use strong or harsh chemical clean-
ers.
Use the same mild detergent and wax as used on the paint.
● Do not use detergent on the wheels when they are hot, for example after
driving for long distance in the hot weather.
● Wash detergent from the wheels immediately after use.
■ Bumpers
Do not scrub with abrasive cleaners.
CAUTION
■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 (veh icles with rain-sensing windshield
wipers)
● When the upper part of the windshi eld 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 pipes
Exhaust gases cause the exhaust pipes to become quite hot.
When washing the vehicle, be careful not to touch the pipes until they have
cooled sufficiently, as touching hot exhaust pipes can cause burns.
■ Precaution regarding the Blind Spot Monitor (if equipped)
If the paint of the rear bumper is chipped or scratched, the system may mal-
function. If this occurs, consult your Toyota dealer.
Set the wiper switch to off.
If the wiper switch is in “AUTO”, the wip-
ers may operate unexpectedly in the fol-
lowing situations, and may result in
hands being caught or other serious inju-
ries and cause damage to the wiper
blades.

■Repair and replacement
It is recommended that genuine Toyota parts be used for repairs to ensure
performance of each system. If non-Toyota parts are used in replacement or if
a repair shop other than a Toyota dealer performs repairs, confirm the war-
ranty coverage.
■ Reset the maintenance data
After the required maintenance is performed according to the maintenance
schedule, please reset the maintenance data.
To reset the data, follow the procedure described below:
Turn the power switch off with the trip meter A reading shown. ( P. 93)
While pressing the trip meter reset knob ( P. 93), turn the power switch to
ON mode
Continue to press and hold the knob until the trip meter displays “000000”.
■ Allow inspection and repairs to be performed by a Toyota dealer
●Toyota technicians are well-trained specialists and are kept up to date with
the latest service information. They are well informed about the operations
of all systems on your vehicle.
● Keep a copy of the repair order. It proves that the maintenance that has
been performed is under warranty cove rage. If any problem should arise
while your vehicle is under warranty, your Toyota dealer will promptly take
care of it.
CAUTION
■ If your vehicle is not properly maintained
Improper maintenance could result in serious damage to the vehicle and
possible death or serious injury.
■ Handling of the 12-volt battery
●Engine exhaust, some of its constituents, and a wide variety of automobile
components contain or emit chemicals known to the State of California to
cause cancer and birth defects and other reproductive harm. Work in a
well ventilated area.
● Oils, fuels and fluids contained in vehicles as well as waste produced by
component wear contain or emit chemicals known to the State of Califor-
nia to cause cancer and birth defects or other reproductive harm. Avoid
exposure and wash any affected area immediately.
● 12-volt battery posts, terminals and related accessories contain lead and
lead compounds which are known to cause brain damage. Wash your
hands after handling. ( P. 358)
