Driving
*: If equipped
Each time the switch is pressed,
the system changes between
power mode, normal mode, and
ECO drive mode.
1 Normal mode
Provides an optimal balance of fuel
economy, quietness, and dynamic per-
formance. Suitable for normal driving.
2 Power mode
Controls the transmission and engine to
provide quick, powerful acceleration.
Making it suitable for when agile driving
response is desired, such as when driv-
ing on roads with many curves.
When the power mode is selected,
power mode indicator comes on.
3 Eco drive mode
Helps the driver accelerate in an eco-
friendly manner and improve fuel econ-
omy through moderate throttle charac-
teristics and by controlling the operation
of the air conditioning system (heat-
ing/cooling).
When the Eco drive mode is selected,
Eco drive mode indicator comes on.
■Operation of the air conditioning
system in Eco drive mode
Eco drive mode controls the heat- ing/cooling operations and fan speed of
the air conditioning system to enhance fuel efficiency. To improve air condition-ing performance, perform the following
operations:
●Turn off air conditioning eco mode
(vehicles with an automatic air condi- tioning system) ( P.318)
●Adjust the fan speed (P.312, 317)
●Turn off Eco drive mode
■Automatic deactivation of power
mode
If the engine switch is turned off after driving in power mode, the drive mode
will be changed to normal mode.

rear window, and to remove rain-
drops, dew and frost from the out-
side rear view mirrors.
Press the rear window and outside
rear view mirror defoggers switch.

5-1. Using the air conditioning system and defogger
■Fogging up of the windows
●The windows will easily fog up when the humidity in the vehicle is high. Turning “A/C” switch is on will dehu-
midify the air from the outlets and defog the windshield effectively.
●If you turn “A/C” switch is off, the win-dows 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.
●During cooling operation, setting the recirculated air mode will also cool the
vehicle interior effectively.
■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.
●It is recommended that the air condi-
tioning system be set to outside air mode prior to turning the vehicle off.
■Air conditioning filter
 P. 3 7 6
This feature is used to prevent ice
from building up on the windshield
and wiper blades.
Press the switch to turn the system
on/off.
The indicator comes on when the sys-
tem is on.
The windshield wiper de-icer will auto-
matically turn off after approximately 15
minutes.
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 (if equipped)
Do not touch the outside rear view mirror surfaces, as they can become very hot and burn you.
NOTICE
■To prevent battery discharge
Do not leave the air conditioning sys-
tem on longer than necessary when the engine is off.

1Pull the hood lock release lever.
The hood will pop up slightly.
2Push the auxiliary catch lever to
the left and lift the hood.
WARNING
●Do not smoke, cause sparks or expose an open flame to fuel or the
battery. Fuel and battery fumes are flammable.
●Be extremely cautious when work-ing on the battery. It contains poi-sonous 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 engine switch is OFF. With the engine 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.357)
■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.

If the level is on or below the “L” line,
add coolant up to the “F” line. ( P.442)
■Coolant selection
Only use “Toyota Super Long Life Cool- ant” or a similar high quality ethylene
glycol based non-silicate, non-amine, non-nitrite, and non-borate coolant with long-life hybrid organic acid technology.
“Toyota Super Long Life Coolant” is a mixture of 50% coolant and 50% deion-ized water. (Minimum temperature: -
35°C [-31°F])
For more details about coolant, contact any authorized Toyota retailer or Toyota
authorized repairer, or any reliable repairer.
■If the coolant level drops within a short time of replenishing
Visually check the radiator, hoses, engine coolant reservoir caps, drain cock and water pump.
If you cannot find a leak, have any authorized Toyota retailer or Toyota authorized repairer, or any reliable
repairer, test the cap and check for leaks in the cooling system.
Check the radiator, condenser clear
away any foreign objects. If either
of the above parts is extremely dirty
or you are not sure of their condi-
tion, have your vehicle inspected by
any authorized Toyota retailer or
Toyota authorized repairer, or any
reliable repairer.
WARNING
■When the engine is hot
Do not remove the engine coolant
reservoir cap. ( P.443)
The cooling system may be under pressure and may spray hot coolant if
the cap is removed, causing serious injuries, such as burns.
NOTICE
■When adding coolant
Coolant is neither plain water nor straight antifreeze. The correct mix-
ture of water and antifreeze must be used to provide proper lubrication, corrosion protection and cooling. Be
sure to read the antifreeze or coolant label.
■If you spill coolant
Be sure to wash it off with water to prevent it from damaging parts or
paint.

rized Toyota retailer or Toyota authorized repairer, or any reliable repairer.
NOTICE
■When handling jumper cables
When connecting the jumper cables,
ensure that they do not become entangled in the cooling fan or engine drive belt.
If your vehicle overheats
The following may indicate that
your vehicle is overheating.
 The engine coolant tempera-
ture gauge ( P.85, 89) is in
the red zone or a loss of
engine power is experienced.
(For example, the vehicle
speed does not increase.)
