MIRAI_OM_USA_OM62023U
NOTICE
■To prevent key damage
● Do not drop the keys, subject them to strong shocks or bend them.
● Do not expose the keys to high temperatures for long periods of time.
● Do not get the keys wet or wash them in an ultrasonic washer, etc.
● Do not attach metallic or magnetic materials to the keys or place the keys
close to such materials.
● Do not disassemble the keys.
● Do not attach a sticker or anything else to the surface of the electronic key.
● Do not place the keys near objects that produce magnetic fields, such as
TVs, audio systems and induction cookers, or medical electrical equip-
ment, such as low-frequency therapy equipment.
■ Carrying the electronic key on your person
Carry the electronic key 3.9 in. (10 cm) or more away from electric appli-
ances that are turned on. Radio wave s emitted from electric appliances
within 3.9 in. (10 cm) of the electronic key may interfere with the key, caus-
ing the key to not function properly.
■ In case of a smart key system malfunction or other key-related prob-
lems
Take your vehicle with all the electronic keys provided with your vehicle to
your Toyota dealer.
■ When an electronic key is lost
If the electronic key remains lost, the risk of vehicle theft increases signifi-
cantly. Visit your Toyota dealer immediately with all remaining electronic
keys that were provided with your vehicle.

Conditions affecting operation
The smart key system uses weak radio waves. In the following situations, the
communication between the electronic key and the vehicle may be affected,
preventing the smart key system, wireless remote control and immobilizer
system from operating properly. (Ways of coping: →P. 398)
● When the electronic key battery is depleted
● Near a TV tower, electric power plant, gas station, radio station, large dis-
play, airport or other facility that generates strong radio waves or electrical
noise
● When the electronic key is in contact with, or is covered by the following
metallic objects
• Cards to which aluminum foil is attached
• Cigarette boxes that have aluminum foil inside
• Metallic wallets or bags
• Coins
• Hand warmers made of metal
• Media such as CDs and DVDs
● When other wireless keys (that emit radio waves) are being used nearby
● When carrying the electronic key together with the following devices that
emit radio waves
• Portable radio, cellular phone, cordless phone or other wireless commu-
nication devices
• Another vehicle’s electronic key or a wireless key that emits radio waves
• Personal computers or personal digital assistants (PDAs)
• Digital audio players
• Portable game systems
● If window tint with a metallic content or metallic objects are attached to the
rear window
● When the electronic key is placed near a battery charger or electronic
devices
1745-2. Driving procedures
MIRAI_OM_USA_OM62023U
Modes can be changed by pressing the power switch with brake pedal
released. (The mode c hanges each time the switch is pressed.)
Off
The emergency flashers can be
used.
ACCESSORY mode
Some electrical components such
as the audio system can be used.
“Accessory” will be displayed on
the main display.
ON mode
All electrical components can be
used.
“Ignition On” will be displayed on
the main display.
■ Auto power off function
If the vehicle is left in ACCESSORY mode for more than 20 minutes or ON
mode (the fuel cell system is not operating) for more than an hour with the
shift position in P, the power switch will automatically turn off. However, this
function cannot entirely prevent 12-volt battery discharge. Do not leave\
the
vehicle with the power switch in ACCESSORY or ON mode for long periods
of time when the fuel cell system is not operating.

■Temporary cancelation of the LDA system functions
If any of the following occurs, the LDA system functions will be temporarily
canceled. The functions will resume after the necessary operating conditions
have returned.
●The turn signal lever is operated.
● The vehicle speed deviates from the operating range of the LDA system
functions.
● When the lane lines cannot be recognized while driving.
● When the lane departure warning function is activated.
The lane departure warning function will not operate again for a several sec-
onds after it has been activated, even if the vehicle leaves the lane again.
■ Alert buzzer for lane departure alert
Depending on the audio system sound level or air conditioning fan noise
while the audio system or air conditioning system is in use, it may be difficult
to hear the alert buzzer.
■ After the vehicle has been parked in the sun
The LDA system may not be available and a warning message is displayed
for a while after driving has started. When the temperature in the cabin
decreases and the temperature around the camera sensor ( →P. 216)
becomes suitable for its operation, turn the LDA switch on again after a
short time.
■ If there are lane markers on only one side of the vehicle
The lane departure alert will not operate for the side on which lane markers
could not be recognized.
2305-5. Using the driving support systems
MIRAI_OM_USA_OM62023U●
The following situations may occur during use.
• Depending on the shape of the obstacle and other factors, the detection
distance may shorten, or detection may be impossible.
• Obstacles may not be detected if they are too close to the sensor.
• There will be a short delay between obstacle detection and display. Even at slow speeds, there is a possibility that the obstacle will come within the
sensor’s detection areas before the display is shown and the buzzer
sounds.
• Thin posts or objects lower than the sensor may not be detected when approached, even if they have been detected once.
• It might be difficult to hear beeps due to the volume of audio system or air flow noise of the air conditioning system.
■ If “Clean Parking Assist Sensor” is displayed on the multi-information
display
A sensor may be dirty or covered with snow or ice. In such cases, if it is
removed from the sensor, the system should return to normal.
Also, due to the sensor being frozen at low temperatures, a malfunction dis-
play may appear or an obstacle may not be detected. If the sensor thaws out,
the system should return to normal.
■ If “Parking Assist Malfunction” is displayed on the multi-information dis-
play
Depending on the malfunction of the sensor, the device may not be working
normally.
Have the vehicle inspected by your Toyota dealer.
■ Certification for the intuitive parking assist
This device complies with Part 15 of the FCC Rules. Operation is subject to
the following two conditions: (1) This device may not cause harmful interfer-
ence, and (2) This device must accept any interference received, including
interference that may cause undesired operation.
■ Customization
Settings (e.g. buzzer sounds volume) can be changed.
(Customizable features: →P. 228, 440)
WARNING
■When using the intuitive parking assist
Observe the following precautions.
Failing to do so may result in the vehicle being unable to be driven safely
and possibly cause an accident.
● Do not use the sensor at speeds in excess of 6 mph (10 km/h).
● The sensors’ detection areas and reaction times are limited. When moving
forward or reversing, check the areas surrounding the vehicle (especially
the sides of the vehicle) for safety, and drive slowly, using the brake to
control the vehicle’s speed.
● Do not install accessories within the sensors’ detection areas.
