■ Idling time before engine stop (diesel engine only)
To prevent damage to the turbocharger, allow the engine to idle immediately
after high-load driving.
*: See “Checking your vehicle’s model” if you are not sure of which model
your vehicle is. ( P. 11 )
■ Operating your vehicle in a foreign country
Comply with the relevant vehicle registration laws and confirm the availability
of the correct fuel. ( P. 660)
■ Eco-friendly driving
 P. 130
■ After driving on muddy roads in poor condition (for EURO VI models*)
Check the cooling fins of the urea injector and clear away any foreign objects
or substances such as leaves or mud. If any of the above parts is extremely
dirty or you are not sure of their condition, have your vehicle inspected by any
authorized Toyota retailer or Toyota authorized repairer, or any reliable
repairer.
*: EURO VI is an emission standard. If it is not clear that your vehicle meets
relevant standards, contact any authorized Toyota retailer or Toyota autho-
rized repairer, or any reliable repairer.

■S mode
When the shift range is 4 or lower, holding the shift lever toward “+” sets the
shift range to 6.
■ Downshifting restrictions warning buzzer
To help ensure safety and driving per formance, downshifting operation may
sometimes be restricted. In some circumstances, downshifting may not be
possible even when the shift lever is operated. (A buzzer will sound twice.)
■ Operation of the air conditioning system in Eco drive mode (vehicles
with automatic air conditioning system)
Eco drive mode controls the heating/cooling operations and fan speed of the
air conditioning system to enhance fuel efficiency ( P. 497). To improve air
conditioning performance, adjust the fan speed or turn off Eco drive mode.
■ Deactivation of the driving mode
● Eco drive mode will not be canceled until the “ECO MODE” switch is
pressed, even if the engine is turned off after driving in Eco drive mode.
● Power mode will be canceled if the engine is turned off after driving in power
mode.
■ When driving with cruise control activated (if equipped)
Even when performing the following actions with the intent of enabling engine
braking, engine braking will not activate because cruise control will not be
canceled.
● While driving in S mode, downshifting to 5 or 4. (P. 280)
● When switching the driving mode to power mode while driving in D.
( P. 279)
■ Shift lock system
The shift lock system is a system to prevent accidental operation of the shift
lever in starting.
The shift lever can be shifted from P only when the engine switch is in the
“ON” position (vehicles without smart entry & start system) or IGNITION ON
mode (vehicles with smart entry & start system) and the brake pedal is being
depressed.

■ Operation of the air conditioning system in Eco drive mode (vehicles
with automatic air conditioning system)
Eco drive mode controls the heating/cooling operations and fan speed of the
air conditioning system to enhance fuel efficiency ( P. 497). To improve air
conditioning performance, adjust the fan speed or turn off Eco drive mode.
■ Deactivation of the driving mode
● Eco drive mode will not be canceled until the “ECO MODE” button is
pressed, even if the engine is turned off after driving in Eco drive mode.
● Power mode will be canceled if the engine is turned off after driving in power
mode.
■ Reverse warning buzzer (6-speed transmission)
A buzzer will sound to alert the driver if the shift lever is shifted to the R posi-
tion.

■Fogging up of the windows
● The windows will easily fog up when the humidity in the vehicle is high.
Turning (if equipped) on will dehumidify the air from the outlets and
defog the windshield effectively.
● If you turn (if equipped) off, the windows may fog up more easily.
● The windows may fog up if the recirculated air mode is used.
■ Outside/recirculated air mode
When driving on dusty roads such as tunnels or in heavy traffic, set the out-
side/recirculated air mode lever to . This is effective in preventing outside
air from entering the vehicle interior . 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) (vehicles with
)
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.

■ Air conditioning system operations when the engine is stopped due to
the Stop & Start system (vehicles with Stop & Start system)
When the engine is stopped due to Stop & Start system operations, the man-
ual air conditioning cooling, heating and dehumidification functions turn off.
To stop the air conditioning system from turning off, press the Stop & Start
cancel switch and refrain from using the Stop & Start system.
■ An odor comes from the air conditioning system due to the Stop & Start
system operation (vehicles with Stop & Start system)
When the engine is stopped due to Stop & Start system operations, an odor
caused by moisture may be detected. This does not indicate a malfunction.

■Using automatic mode
Fan speed is adjusted automatically according to the temperature setting and
the ambient conditions.
Therefore, the fan may stop for a while until warm or cool air is ready to flow
immediately after is pressed.
■ 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.
■ Outside/recirculated air mode
● When driving on dusty roads such as tunnels or in heavy traffic, press .
This is effective in preventing outside air from entering the vehicle interior.
During cooling operation, setting the reci rculated 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.
■ Operation of the air conditioning system in Eco drive mode (if equipped)
● In Eco drive mode, the air conditioning system is controlled as follows to pri-
oritize fuel efficiency:
• Engine speed and compressor operation controlled to restrict heating/
cooling capacity
• Fan speed restricted when automatic mode is selected
● To improve air conditioning performance, perform the following operations.
• Adjust the fan speed
• Turn off Eco drive mode
• Adjust the temperature setting
■ When the outside temperature falls to nearly 0°C (32°F)
The dehumidification function may not operate even when is pressed.

mode prior to turning the vehicle off.
• For some models: 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.
■ Air conditioning system operations when the engine is stopped due to
the Stop & Start system (vehicles with Stop & Start system)
When the engine is stopped due to Stop & Start system operations, the
automatic air conditioning cooling, heating and dehumidification functions
turn off and the fan speed is decreased according to the outside tempera-
ture etc. or air blowing stops. To stop the air conditioning system from turn-
ing off, press the Stop & Start cancel switch and refrain from using the Stop
& Start system.
■ An odor comes from the air conditioning system due to the Stop & Start
system operation (vehicles with Stop & Start system)
