WARNING

■

Using the trunk

Observe the following precautions.
Failure to do so may cause parts of the body to be caught, resulting in seri-
ous injury.

●

Remove any heavy loads, such as snow and ice, from the trunk lid before
opening it. Failure to do so may cause the trunk lid to suddenly shut again
after it is opened.

●

When opening or closing the trunk lid, thoroughly check to make sure the
surrounding area is safe. 

●

If anyone is in the vicinity, make sure they are safe and let them know that
the trunk is about to open or close.

●

Use caution when opening or closing the trunk lid in windy weather as it
may move abruptly in strong wind.

●

Do not attach any accessories other than genuine Toyota parts to the trunk
lid. Such additional weight on the trunk lid may cause the lid to suddenly
shut again after it is opened. 

●

The  trunk  lid  may  suddenly  shut  if  it  is
not  opened  fully.  It  is  more  difficult  to
open or close the trunk lid on an incline
than  on  a  level  surface,  so  beware  of
the  trunk  lid  unexpectedly  opening  or
closing  by  itself.  Make  sure  that  the
trunk lid is fully open and secure before
using the trunk. 

●

When  closing  the  trunk  lid,  take  extra
care  to  prevent  your  fingers,  etc.,  from
being caught.

●

When closing the trunk lid, make sure to
press it lightly on its outer surface. If the
trunk  handle  is  used  to  fully  close  the
trunk lid, it may result in hands or arms
being caught.

Note for the entry function

●

Even when the electronic key is within the effective range (detection areas),
the system may not operate properly in the following cases:
• The electronic key is too close to the window or outside door handle, near

the ground, or in a high place when the doors are locked or unlocked.

• The electronic key is near the ground or in a high place, or too close to

the rear bumper center when the trunk is opened.

• The electronic key is on the instrument panel, rear package tray or floor,

or in the door pockets or glove box when the fuel cell system is started or
power switch modes are changed.

●

Do not leave the electronic key on top of the instrument panel or near the
door pockets when exiting the vehicle. Depending on the radio wave recep-
tion conditions, it may be detected by the antenna outside the cabin and the
door will become lockable from the outside, possibly trapping the electronic
key inside the vehicle.

●

As long as the electronic key is within the effective range, the doors may be
locked or unlocked by anyone. However, only the doors detecting the elec-
tronic key can be used to unlock the vehicle.

●

Even if the electronic key is not inside the vehicle, it may be possible to start
the fuel cell system if the electronic key is near the window.

●

The  doors may unlock or lock  if a  large  amount  of water  splashes on  the
door handle, such as in the rain or in a car wash when the electronic key is
within  the  effective  range.  (The  doors  will  automatically  be  locked  after
approximately 60 seconds if the doors are not opened and closed.)

●

If the wireless remote control is used to lock the doors when the electronic
key  is  near  the  vehicle,  there  is  a  possibility  that  the  door  may  not  be
unlocked by the entry function. (Use the wireless remote control to unlock
the doors.)

●

Touching the door lock or unlock sensor while wearing gloves may prevent
lock or unlock operation.

●

When the lock operation is performed using the lock sensor, recognition sig-
nals  will  be  shown  up  to  two  consecutive  times. After  this,  no  recognition
signals will be given.

●

If the door handle becomes wet while the electronic key is within the effec-
tive range, the door may lock and unlock repeatedly. In this case, follow the
following correction procedures to wash the vehicle:
• Place the electronic key in a location 6 ft. (2 m) or more away from the

vehicle. (Take care to ensure that the key is not stolen.)

• Set  the  electronic  key  to  battery-saving  mode  to  disable  the  smart  key

system. (



P. 145)

●

If the electronic key is inside the vehicle and a door handle becomes wet
during a car wash, a message may be shown on the multi-information dis-
play and a buzzer will sound outside the vehicle. To turn off the alarm, lock
all the doors.

4-2. Opening, closing and locking the doors

MIRAI_OM_USA_OM62073U

●

The  lock  sensor  may  not  work  properly  if  it  comes  into  contact  with  ice,
snow, mud, etc. Clean the lock sensor and attempt to operate it again.

●

A sudden approach to the effective range or door handle may prevent the
doors from being unlocked. In this case, return the door handle to the origi-
nal position and check that the doors unlock before pulling the door handle
again.

●

If there is another electronic key in the detection area, it may take slightly
longer to unlock the doors after the door handle is gripped. 

■

When the vehicle is not driven for extended periods

●

To prevent theft of the vehicle, do not leave the electronic key within 6 ft. (2 m)
of the vehicle.

●

The smart key system can be deactivated in advance. (



P. 486)

■

To operate the system properly

●

Make sure to carry the electronic key when operating the system. Do not get
the electronic key too close to the vehicle when operating the system from the
outside of the vehicle. 
Depending on the position and holding condition of the electronic key, the key
may not be detected correctly and the system may not operate properly. (The
alarm may go off accidentally, or the door lock prevention function may not
operate.)

●

Do not leave the electronic key inside the trunk. 
The  key  confinement  prevention  function  may  not  operate,  depending  on
the location of the key (close to the emergency tire puncture repair kit, the
inside edge of the trunk), conditions (inside a metal bag, close to metallic
objects) and the radio waves in the surrounding area. (

When the mirror select switch is in the “L” or “R” position, the outside
rear view mirrors will automatically angle downwards when the vehicle
is reversing in order to give a better view of the ground. 
To disable this function, move the mirror select switch to the neutral
position (between “L” or “R”)

■

Adjusting the mirror angle when the vehicle is reversing

With the shift position in R, adjust the mirror angle at a desired posi-
tion. 
The adjusted angle will be memorized and the mirror will automati-
cally  tilt  to  the  memorized  angle  whenever  the  shift  position  is
shifted to R from next time.

The memorized downward tilt position of the mirror is linked to the nor-
mal  position  (angle  adjusted  with  the  shift  position  in  other  than  R).
Therefore,  if  the  normal  position  is  changed  after  adjustment,  the  tilt
position will also change.
When the normal position is changed, readjust the angle in reversing.

■

Mirror angle can be adjusted when

The power switch is in ACCESSORY or ON mode.

■

Rain clearing mirrors

The coating on the mirror has the rain clearing (hydrophilic) effect to make the
rear view clearer in raining. When water droplets collect on the mirror surface,
this effect causes the droplets to be spread out into a film.

●

The rain clearing effect will be reduced temporarily, when the dirt is adhered
to the mirror or after your vehicle is parked for a long time in underground or
indoor parking lots, etc., where there is no direct sunlight. 
However, the effect will gradually recover after 1- or 2-day exposure to direct
sunlight.

●

If you want to restore the rain clearing effect immediately, conduct the resto-
ration work. (

P. 353)

■

When the mirrors are fogged up

The outside rear view mirrors can be cleared using the mirror defoggers. Turn
on the rear window defogger to turn on the outside rear view mirror defog-

Important points while driving

Observe the following precautions while driving.
Failure to do so may result in loss of control of the vehicle and cause an
accident, resulting in death or serious injury.

●

Do not adjust the mirrors while driving.

●

Do not drive with the mirrors folded.

●

Both the driver and passenger side mirrors must be extended and properly
adjusted before driving.

■

When a mirror is moving

To avoid personal injury and mirror malfunction, be careful not to get your
hand caught by the moving mirror.

■

When the mirror defoggers are operating

Do not touch the rear view mirror surfaces, as they can become very hot
and burn you.

NOTICE

■

Handling the rain clearing mirror

The rain clearing effect is finite. Observe the following precautions in order
to retain the rain-clearing properties of the mirrors:

●

When using water repellent, oil film remover, wax, or any other car mainte-
nance product that contains silicone, pay full attention not to adhere it to
the mirror surface.

●

Do not wipe the mirror surface by using any cloth smeared with sand, oil
film remover, abrasive agent, or any other thing that may scratch the mir-
ror surface.

●

When  the  mirrors  become  iced  up,  remove  the  ice  by  applying  warm
water, or operating the outside rear view mirror defoggers. 
But, do not attempt to scrape the ice off by using the plastic plate, etc.

●

When washing your vehicle using car shampoo with water repellent effect,
rinse the mirror surface with a lot of water, and remove the water drops by
using a clean and soft cloth.

cially slippery.

●

Refrain  from  high  speeds  when  driving  on  an  expressway  in  the  rain,
because there may be a layer of water between the tires and the road sur-
face, preventing the steering and brakes from operating properly.

■

Restraining the fuel cell system output (Brake Override System)

●

When the accelerator and brake pedals are depressed at the same time, the
fuel cell system output may be restrained.

Breaking in your new Toyota

To extend the life of the vehicle, observing the following precautions is recom-
mended:

●

For the first 200 miles (300 km):
Avoid sudden stops.

●

For the first 1000 miles (1600 km):

Drum-in-disc type parking brake system

Your vehicle has a drum-in-disc type parking brake system. This type of brake
system needs bedding-down of the brake shoes periodically or whenever the
parking brake shoes and/or drum are replaced. Have your Toyota dealer per-

WARNING

Observe the following precautions. 
Failure to do so may result in death or serious injury.

■

When starting the vehicle

Always keep your foot on the brake pedal while stopped with the “READY”
indicator is illuminated. This prevents the vehicle from creeping.

■

When driving the vehicle

●

Do not drive if you are unfamiliar with the location of the brake and accel-
erator pedals to avoid depressing the wrong pedal. 
• Accidentally  depressing  the  accelerator  pedal  instead  of  the  brake

pedal will result in sudden acceleration that may lead to an accident.

• When backing up, you may twist your body around, leading to difficulty

in operating the pedals. Make sure to operate the pedals properly.

• Make  sure  to  keep  a  correct  driving  posture  even  when  moving  the

vehicle only slightly. This allows you to depress the brake and accelera-
tor pedals properly.

• Depress  the  brake  pedal  using  your  right  foot.  Depressing  the  brake

pedal using your left foot may delay response in an emergency, result-
ing in an accident.

●

The driver should pay extra attention to pedestrians when the fuel cell sys-
tem is on. As there are no engine sounds, pedestrians may misjudge the
vehicle’s movement.

●

During normal driving, do not turn off the fuel cell system. Turning the fuel
cell system off while driving will not cause loss of steering or braking con-
trol,  however,  power  assist  to  the  steering  will  be  lost.  This  will  make  it
more difficult to steer smoothly, so you should pull over and stop the vehi-

WARNING

Observe the following precautions. 
Failure to do so may result in death or serious injury.

■

When driving the vehicle

●

Do not drive in excess of the speed limit. Even if the legal speed limit per-
mits it, do not drive over 85 mph (140 km/h) unless your vehicle has high-
speed capability tires. Driving over 85 mph (140 km/h) may result in tire
failure, loss of control and possible injury. Be sure to consult a tire dealer
to  determine whether the  tires on your  vehicle are high-speed capability
tires or not before driving at such speeds.

■

When driving on slippery road surfaces

●

Sudden  braking,  acceleration  and  steering  may  cause  tire  slippage  and
reduce your ability to control the vehicle.

●

Sudden acceleration or regenerative braking due to shifting could cause
the vehicle to skid.

●

After  driving  through  a  puddle,  lightly  depress  the  brake  pedal  to  make
sure that the brakes are functioning properly. Wet brake pads may prevent
the brakes from functioning properly. If the brakes on only one side are wet
and not functioning properly, steering control may be affected.

■

When changing the shift position

●

Do  not  let  the  vehicle  roll  backward  while  a  forward  driving  position  is
selected, or roll forward while the shift position is in R.
Doing so may result in an accident or damage to the vehicle.

●

Do not shift the shift position to P while the vehicle is moving. 
Doing so can damage the transmission and may result in a loss of vehicle
control.

●

Do not shift the shift position to R while the vehicle is moving forward. 
Doing so can damage the transmission and may result in a loss of vehicle
control.

●

Do not shift the shift position to a driving position while the vehicle is mov-
ing backward. 
Doing so can damage the transmission and may result in a loss of vehicle
control.

●

Shifting the shift position to N while the vehicle is moving will disengage
the fuel cell system. Regenerative braking is not available with the fuel cell
system disengaged.

●

Be  careful  not  to  shift  the  shift  position  with  the  accelerator  pedal
depressed. Shifting the shift position to any position other than P or N may
lead  to  unexpected  rapid  acceleration  of  the  vehicle  that  may  cause  an
accident and result in death or serious injury. 
After shifting the shift position, make sure to check the current shift posi-
tion using the shift position indicator. (

WARNING

Observe the following precautions. 
Failure to do so may result in death or serious injury.

■

If you hear a squealing or scraping noise (brake pad wear limit indica-
tors)

Have the brake pads checked and replaced by your Toyota dealer as soon
as possible. 
Rotor damage may result if the pads are not replaced when needed.
It is dangerous to drive the vehicle when the wear limits of the brake pads
and/or those of the brake discs are exceeded.

■

When the vehicle is stopped

●

Do not depress the accelerator pedal unnecessarily.
If the shift position is in any position other than P or N, the vehicle may
accelerate suddenly and unexpectedly, causing an accident.

●

In order to prevent accidents due to the vehicle rolling away, always keep
depressing the  brake  pedal while stopped with the  “READY” indicator  is
illuminated, and apply the parking brake as necessary.

●

If the vehicle is stopped on an incline, in order to prevent accidents caused
by the vehicle rolling forward or backward, always depress the brake pedal
and securely apply the parking brake as needed.

■

When the vehicle is parked

●

Do not leave glasses, cigarette lighters, spray cans, or soft drink cans in
the vehicle when it is in the sun.
Doing so may result in the following:
• Gas may leak from a cigarette lighter or spray can, and may lead to a

fire.

• The  temperature  inside  the  vehicle  may  cause  the  plastic  lenses  and

plastic material of glasses to deform or crack.

• Soft  drink  cans  may  rupture,  causing  the  contents  to  spray  over  the

interior of the vehicle, and may also cause a short circuit in the vehicle’s
electrical components.

●

Do not leave cigarette lighters in the vehicle. If a cigarette lighter is in a
place such as the glove box or on the floor, it may be lit accidentally when
luggage is loaded or the seat is adjusted, causing a fire.

●

Do not attach adhesive discs to the windshield or windows. Do not place
containers such as air fresheners on the instrument panel or dashboard.
Adhesive discs or containers may act as lenses, causing a fire in the vehi-
cle.

WARNING

Observe the following precautions. 
Failure to do so may result in death or serious injury.

■

When the vehicle is parked

●

Do not leave a door or window open if the curved glass is coated with a

metallized film such as a silver-colored one. Reflected sunlight may cause

the glass to act as a lens, causing a fire.

●

Always apply the parking brake, shift the shift position to P, stop the fuel

cell system and lock the vehicle. 

Do not leave the vehicle unattended while the “READY” indicator is illumi-

nated.

If the vehicle is parked with the shift position in P but the parking brake is

not set, the vehicle may start to move, possibly leading to an accident.

■

When taking a nap in the vehicle

Always turn the fuel cell system off. Otherwise, if you accidentally move the

shift lever or depress the accelerator pedal, causing the vehicle to uninten-

tionally move, which can lead to an accident, resulting in death or serious

injury.

■

When braking

●

When the brakes are wet, drive more cautiously.

Braking distance increases when the brakes are wet, and this may cause

one side of the vehicle to brake differently than the other side. Also, the

parking brake may not securely hold the vehicle.

●

If the electronically controlled brake system does not operate, do not fol-

low other vehicles closely and avoid hills or sharp turns that require brak-

ing.

In  this  case,  braking  is  still  possible,  but  the  brake  pedal  should  be

depressed more firmly than usual. Also, the braking distance will increase.

Have your brakes fixed immediately.

●

The  brake  system  consists  of  2  or  more  individual  hydraulic  systems;  if

one  of  the  systems  fails,  the  other(s)  will  still  operate.  In  this  case,  the

brake pedal should be depressed more firmly than usual and the braking

distance will increase. Have your brakes fixed immediately. 

NOTICE

■

When driving the vehicle

●

Do not depress the accelerator and brake pedals at the same time during
driving, as this may restrain the fuel cell system output.

●

Do  not  use  the  accelerator  pedal  or  depress  the  accelerator  and  brake
pedals at the same time to hold the vehicle on a hill.

■

When parking the vehicle

Always set the parking brake, and shift the shift position to P. Failure to do
so may cause the vehicle to move or the vehicle may accelerate suddenly if
the accelerator pedal is accidentally depressed.

■

When encountering flooded roads

Do not drive on a road that has flooded after heavy rain, etc. Doing so may
cause the following serious damage to the vehicle:

●

Fuel cell system stalling

●

Short in electrical components

●

Fuel cell system damage caused by water immersion

In the event that you drive on a flooded road and the vehicle is flooded, be
sure to have your Toyota dealer check the following:

●

Fuel cell system

●

Brake function

●

Changes in quantity and quality of transmission fluid, etc.

●

Lubricant condition for the bearings and suspension joints (where possi-
ble), and the function of all joints, bearings, etc.

If the shift control system is damaged by flooding, it may not be possible to
shift the shift position to P, or from P to other positions. When the shift posi-
tion cannot be changed from P to any other position, the front wheels will
lock, and you will be unable to tow the vehicle with the front wheels on the
ground, as the front wheels may be locked. In this case, transport the vehi-
cle with both front wheels or all four wheels lifted.

Cargo and luggage

Cargo capacity depends on the total weight of the occupants. 
(Cargo capacity) = (Total load capacity) — (Total weight of occupants)

Steps for Determining Correct Load Limit —

(1) Locate  the  statement  “The  combined  weight  of  occupants  and

cargo should never exceed XXX kg or XXX lbs.” on your vehicle’s
placard. 

(2) Determine the combined weight of the driver and passengers that

will be riding in your vehicle. 

(3) Subtract  the  combined  weight  of  the  driver  and  passengers  from

XXX kg or XXX lbs.

(4) The resulting figure equals the available amount of cargo and lug-

gage load capacity. 
For example, if the “XXX” amount equals 1400 lbs. and there will be
five  150  lb  passengers  in  your  vehicle,  the  amount  of  available
cargo and luggage load capacity is 650 lbs. (1400 



 750 (5



150) =

650 lbs.) 

(5) Determine the combined weight of luggage and cargo being loaded

on  the  vehicle.  That  weight  may  not  safely  exceed  the  available
cargo and luggage load capacity calculated in Step 4. 

(6) If your vehicle will be towing a trailer, load from your trailer will be

transferred to your vehicle. Consult this manual to determine how
this reduces the available cargo and luggage load capacity of your
vehicle.
 (

increases, the cargo and luggage load will be reduced by an amount
that equals the increased weight due to the additional occupants. In
other  words,  if  an  increase  in  the  number  of  occupants  causes  an
excess of the total load capacity (combined weight of occupants plus

For the shift positions

●

When the power switch is off, the shift position cannot be changed.

●

When the power switch is in ON mode (the fuel cell system is not operating),
the  shift  position  can  only  be  changed  to  N.  The  shift  position  will  be
changed to N even if the shift position is shifted to D or R and held in that
position.

●

When the “READY” indicator is on, the shift position can be changed from P
to D, N or R.

●

When  the  “READY”  indicator  is  flashing,  the  shift  position  cannot  be
changed from P to another position even if the shift lever is operated.
Wait until the “READY” indicator changes from a flashing to a solid light, and
then operate the shift lever again.

In addition, if an attempt is made to change the shift position by moving the
shift lever or by pressing the P position switch in any of the following situa-
tions,  a  buzzer  will  sound  and  the  shifting  operation  will  be  disabled  or  the
shift  position  will  automatically  change  to  N.  When  this  happens,  select  an
appropriate shift position.

●

When attempting to change the shift position from P without depressing the
brake pedal, the shift position change is invalidated.

●

Situations where the shift position will automatically change to N:
• When the P position switch is pressed while the vehicle is running.

Shifting from P on a slope

When changing to another position from P when parked on a slope in the P
position, vibrations may be felt.

WARNING

■

When driving on slippery road surfaces

Do not accelerate or shift the shift position suddenly. 
Sudden changes in regenerative braking may cause the vehicle to spin or
skid, resulting in an accident.

■

For the shift lever

Do not  remove  the shift  lever knob  or  use  anything  but  a genuine Toyota
shift lever knob. Also, do not hang anything on the shift lever. 
Doing  so  could  prevent  the  shift  lever  from  returning  to  position,  causing
unexpected accidents to occur when the vehicle is in motion.
