Decreases the sensitivity
Washer/wiper dual operation
The wipers will automatically
operate a couple of times after
the washer squirts.
■The windshield wipers and washer can be operated when
The engine switch is in the “ON” position (vehicles without a smart key sys-
tem) or IGNITION ON mode (vehicles with a smart key system).
■ Raindrop sensor (vehicles with ra in-sensing windshield wipers)
● If the wiper switch is turned to “AUTO” position while the engine switch is in
IGNITION ON mode, the wiper will operate once to show that “AUTO” mode
is activated.
● If the temperature of the raindrop sensor is 185°F (85°C) or higher, or 14°F
(-10°C) or lower, automatic operation may not occur. In this case, operate
the wipers in any mode other than “AUTO”.
■ If no windshield washer fluid sprays
Check that the washer nozzles are not blocked if there is washer fluid in the
windshield washer fluid reservoir.

4-4. Refueling
Opening the fuel tank cap
●Close all the doors and windows, and turn the engine switch to the
“LOCK” position (vehicles without a smart key system) or off (vehi-
cles with a smart key system).
● Confirm the type of fuel.
■Fuel type
Unleaded gasoline (Octane rating 87 [Research Octane Number 91] or
higher)
Perform the following steps to open the fuel tank cap:
Before refueling the vehicle
WARNING
■When refueling the vehicle
Observe the following precautions while refueling the vehicle. Failure to do
so may result in death or serious injury.
● After exiting the vehicle and before opening the fuel door, touch an
unpainted metal surface to discharge any static electricity. It is important to
discharge static electricity before refueling because sparks resulting from
static electricity can cause fuel vapors to ignite while refueling.
● Always hold the grips on the fuel tank cap and turn it slowly to remove it.
A whooshing sound may be heard when the fuel tank cap is loosened.
Wait until the sound cannot be heard before fully removing the cap.
In hot weather, pressurized fuel may spray out of the filler neck and cause
injury.
● Do not allow anyone that has not discharged static electricity from their
body to come close to an open fuel tank.
● Do not inhale vaporized fuel.
Fuel contains substances that are harmful if inhaled.
● Do not smoke while refueling the vehicle.
Doing so may cause the fuel to ignite and cause a fire.
● Do not return to the vehicle or touch any person or object that is statically
charged.
This may cause static electricity to build up, resulting in a possible ignition
hazard.

The vehicle-to-vehicle distance is
set automatically to long mode
when the engine switch is turned to

If a vehicle is running ahead of
you, the preceding vehicle mark
will be also displayed.
Select a distance from the table below. Note that the distances shown
correspond to a vehicle speed of 50 mph (80 km/h). Vehicle-to-vehicle
distance increases/decreases in accordance with vehicle speed.

Driving
Constant speed control mode differs from vehicle-to-vehicle distance
control mode. When cons tant speed control mode is selected, your
vehicle will maintain a set speed re gardless of whether or not there
are other vehicles in the lane ahead.
Press the “ON-OFF” button to
activate the cruise control.
Press the button again to deacti-
vate the cruise control.
Switch to constant speed con-
trol mode.
(Push the lever forward and
hold for approximately one sec-
ond)
Constant speed control mode indicator will be displayed.
When in constant speed control mode, to return to vehicle-to-vehicle dis-
tance control mode, push the leve r forward again and hold for approxi-
mately 1 second.
After the desired speed has been set, it is not possible to return to vehicle-
to-vehicle distance control mode.
If the engine switch is turned off and then turned to IGNITION ON mode
again, the vehicle will automatically return to vehicle-to-vehicle distance
control mode.

4-5. Using the driving support systems
■The intuitive parking assist can be operated when
●The engine switch is in the “ON” position (vehicles without a smart key sys-
tem) or IGNITION ON mode (vehicles with a smart key system).
● Front corner sensors:
• The shift lever is not in P.
• The vehicle speed is approximately 6 mph (10 km/h) or less.
● Rear corner and rear center sensors:
The shift lever is in R.
■ Intuitive parking assist display
When an obstacle is detected while the rear view monitor system is in use,
the warning indicator will appear in the upper corner of the screen even if the
display setting has been set to off.
■ Sensor detection information
●The sensor’s detection areas are limited to the areas around the vehicle’s
bumper.
● Certain vehicle conditions and the surrounding environment may affect the
ability of the sensor to correctly detect obstacles. Particular instances where
this may occur are listed below.
• There is dirt, snow or ice on the sensor. (Wiping the sensors will resolve
this problem.)
• The sensor is frozen. (Thawing the area will resolve this problem.)
In especially cold weather, if a sensor is frozen the screen may show an
abnormal display, or obstacles may not be detected.
• The sensor is covered in any way.
• The vehicle is leaning considerably to one side.
• On an extremely bumpy road, on an incline, on gravel, or on grass
• The vicinity of the vehicle is noisy due to vehicle horns, motorcycle
engines, air brakes of large vehicles, or other loud noises producing ultra-
sonic waves.
• There is another vehicle equipped with parking assist sensors in the
vicinity.
• The sensor is coated with a sheet of spray or heavy rain.
• The vehicle is equipped with a fender pole or wireless antenna.
• The bumper or sensor receives a strong impact.
• The vehicle is approaching a tall or curved curb.
• In harsh sunlight or intense cold weather
• The area directly under the bumpers is not detected.
• If obstacles draw too close to the sensor.
• A non-genuine Toyota suspension (lowered suspension etc.) is installed.
• People may not be detected if they are wearing certain types of clothing.
In addition to the examples above, there are instances in which, because of
their shapes, signs and other objects may be judged by the sensor to be
closer than they are.

4-5. Using the driving support systems
■Screen description
The rear view monitor system screen will be displayed if the shift
lever is shifted to R while the engi ne switch is in the “ON” position
(vehicles without a smart key syst em) or IGNITION ON mode (vehi-
cles with a smart key system).
Vehicle width guide line
The line indicates a guide path when the vehicle is being backed straight
up.
The displayed width is wider than the actual vehicle width.
Vehicle center guide line
These lines indicate the estimated vehicle center on the ground.
Distance guide line
The line shows distance behind the vehicle, a point approximately 1.5 ft.
(0.5 m) (red) from the edge of the bumper.
Distance guide line
The line shows distance behind the vehicle, a point approximately 3 ft.
(1 m) (blue) from the edge of the bumper.

4106-1. Using the air conditioning system and defogger
SIENNA_OM_01999-08001_(U)
■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 the “AUTO” button is pressed.
■ 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 engine switch
is turned to the “ON” position (vehicles without a smart key system) or
IGNITION ON mode (vehicles with a smart key system).
● It is possible to switch to outside air mode at any time by pressing .
■ Fogging up of the windows
●The windows will easily fog up when the humidity in the vehicle is high.
Pressing “A/C” button on will dehumidify the air from the outlets and defog
the windshield effectively.
● If you turn “A/C” 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
to the recirculated air mode. This is effective in preventing outside air from
entering the vehicle interior. During cooling operation, setting the recircu-
lated 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.
