3-1. Using the air conditioning system
and defogger
3
Interior features
■For quick cooling (vehicles wi th air conditioning system)
Turn the temperature control dial to the “MAX A/C” position and select the
recirculated air mode.
■ For quick clearing of th e windshield and side windows (vehicles with
air conditioning system)
Press to turn the air conditioning on.
■ Using the recirculated air mode
The windows will fog up more easily if the recirculated air mode is used for
an extended period.
■ When outside air temperature appro aches 32°F (0°C) (vehicles with air
conditioning system)
The air conditioning system may not operate even when
is pressed.
■ When
is selected for the air outlets used
For your driving comfort, air flowing to the feet may be warmer than air flow-
ing to the upper body depending on the position of the temperature adjust-
ment dial.
CAUTION
■ To prevent the windshield from fogging up
Do not set the air outlet selection dial to during cool air operation in
extremely humid weather. The difference 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.

NOTICE
■To prevent battery discharge
Do not leave the air conditioning system on longer than necessary when the
engine is stopped.

Interior features
Rear window and outside rear view mirror defoggers
■Outside rear view mirror defoggers (if equipped)
Turning the rear window defogger on will turn the outside rear view mirror
defoggers on.
CAUTION
■Outside rear view mirror defoggers (if equipped)
The surfaces of the outside rear view mirrors become hot. Do not touch
them to prevent from burning yourself.
Clear the rear window using the defogger.
Vehicles with automatic air conditioning system
On/off
The defoggers will automati-
cally turn off after approxi-
mately 15 minutes.
Vehicles with manual air conditioning systemOn/off
The defoggers will automati-
cally turn off after approxi-
mately 15 minutes.

3-3. Using the hand
s-free phone system (for cellular phone)
3
Interior features
■Automatic adjustment of volume
When vehicle speed is 50 mph (80 km/h) or more, the volume automatically
increases. The volume returns to the previous volume setting when vehicle
speed drops to 43 mph (70 km/h) or less.
■ When using a voice command
For numbers, say a combination of single digits from zero to nine, # (pound),
 (star), and + (plus).
Say a command correctly and clearly.
■ The system may not recognize your voice in the following situations:
●When driving on a rough road
● When driving at high speeds
● When air is blowing out of the vents onto the microphone
● When the air conditioning fan emits a loud noise
■ The following cannot be performed while driving:
●Operating the system with
● Registering a cellular phone to the system
■ Changing the passkey

Maintenance and care
CAUTION
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 or rags, in the
engine compartment.
● Do not smoke, cause sparks or expose an open flame to fuel or the bat-
tery. Fuel and battery fumes are flammable.
● Be extremely cautious when working on the battery. It contains poisonous
and corrosive sulfuric acid.
● 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, see a doctor.
■ When working near the electric c ooling fans or radiator grille
Vehicles with smart key system: Be sure the “ENGINE START STOP” switch
is OFF. With the “ENGINE START STOP” switch in IGNITION ON mode, the
electric cooling fans may automatically start to run if the air conditioning is on
and/or the coolant temperature is high. ( P. 322)
Vehicles without smart key system: Be sure the engine switch is OFF. With
the engine switch in the “ON” position, the electric cooling fans may auto-
matically start to run if the air conditioning is on and/or the coolant tempera-
ture is high. ( P. 322)
■ Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc. from
getting in the eyes.

Maintenance and care
■When to replace your vehicle’s tires
Tires should be replaced if:
●You have tire damage such as cuts, splits, cracks deep enough to
expose the fabric, or bulges indicating internal damage
●A tire goes flat repeatedly or c
annot be properly repaired due to the
size or location of a cut or other damage
If you are not sure, consult with your Toyota dealer.
■Replacing tires and wheels
If the ID code of the tire pressure warning valve and transmitter is not
registered, the tire pre ssure warning system will not work properly. After
driving for about 20 minutes, the ti re pressure warning light comes on
after blinking for 1 minute to indicate a system malfunction.
■Tire life
Any tire over 6 years old must be checked by a qualified technician even
if they have seldom or never been used or damage is not obvious.
■If the tread wears down below 0.16 in. (4 mm) on snow tires
The effectiveness of snow tires is lost.
■Maximum load of tire
Check that the maximum load of the re placed tire is greater than 1/2 of
the Gross Axle Weight Ratings (GAWR) of either the front axle or the
rear axle, whichever is greater.
For the maximum load of the tire, see the load limit at maximum cold tire
inflation pressure mentioned on the sidewall of the tire, and for the Gross
Axle Weight Ratings (GAWR), s ee the Certification Label. (P. 338,
437).
■Low profile tires (vehicles with 17-inch tires)
Generally, low profile tire s will wear more rapidly and tire grip perfor-
mance will be reduced on snowy and/or icy roads when compared to
standard tires. Be sure to use snow tires or tire chains on snowy and/or
icy roads and drive carefully at a speed appropriate for road and weather
conditions.

Maintenance and care
NOTICE
■Repairing or replacing tires, wheels and tire pressure warning
valves and transmitters
When removing or fitting the wheels, tires or the tire pressure warning
valves and transmitters, contact your
Toyota dealer as the tire pressure
warning valves and transmitters may be damaged if not handled cor-
rectly.
■To avoid damaging the tire pressure warning valves and transmit-
ters
Do not use liquid sealants on flat tires.
■Driving on rough roads
Take particular care when driving on roads with loose surfaces or pot-
holes.
These conditions may cause losses in tire air pressure, reducing the
cushioning ability of the tires. In addition, driving on rough roads may
cause damage to the tires themselves, as well as the vehicle’s wheels
and body.
■Low profile tires and wheels
Wheels with profile tires like 17-inch tires may cause greater damage
than usual to the tire wheel when receiving impact from the road surface.
Therefore pay attention to the following:
●Be sure to use proper tire inflation pressure. If tires are under-inflated,
they may be damaged more severely.
●Avoid pot holes, uneven pavement, curbs and other road hazards.
Failure to do so can lead to severe tire and wheel damage.
■If tire inflation pressures become low while driving
Do not continue driving, or your tires and/or wheels may be ruined.
