• Shift position
• Traction battery status
The recorded data varies according to the vehicle grade level and options
with which it is equipped. These computers do not record conver sations or
sounds, and only record images outside of the vehicle in certai n situations.
●Data Transmission

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 sp eed limit per-
mits it, do not drive over 85 mph (140 km/h) unless your vehicl e has high-
speed capability tires. Driving over 85 mph (140 km/h) may resu lt 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 c apability
tires or not before driving at such speeds.
■ When driving on slippery road surfaces
● Sudden braking, acceleration and steering may cause tire slippa ge and
reduce your ability to control the vehicle.
● Sudden acceleration or regenerative braking due to shifting cou ld 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 m ay 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 movin g.
Doing so can damage the transmission and may result in a loss o f vehicle
control.
● Do not shift the shift position to R while the vehicle is movin g forward.
Doing so can damage the transmission and may result in a loss o f 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 o f vehicle
control.
● Shifting the shift position to N while the vehicle is moving wi ll 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 th an P or N may
lead to unexpected rapid acceleration of the vehicle that may c ause 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. ( P. 179)

NOTICE
■Avoiding damage to vehicle parts
● Do not turn the steering wheel fully in either direction and ho ld it there for
an extended period of time.
Doing so may damage the power steering motor.
● When driving over bumps in the road, drive as slowly as possibl e to avoid
damaging the wheels, underside of the vehicle, etc.
■ If you get a flat tire while driving
A flat or damaged tire may cause the following situations. Hold the steering
wheel firmly and gradually depress the brake pedal to slow down the vehi-
cle.
● It may be difficult to control your vehicle.
● The vehicle will make abnormal sounds or vibrations.
● The vehicle will lean abnormally.
Information on what to do in case of a flat tire ( P. 381)
■ 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 i s 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 (whe re 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. Wh en 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, transp ort the vehi-
cle with both front wheels or all four wheels lifted.
■ If the vehicle will not shift out of the P position
There is a possibility that the 12-volt battery is discharged. Check the
12-volt battery in this situation.

Shift lever
Operate the shift lever gently
and ensure correct shifting
operation.
Release the shift lever after
each shifting operation to allow
it return to the position.When shifting to the D
or R positions, move
the shift lever along the
shift gate.
To shift to the N posi-
tion, slide the shift lever
to the left and hold it.
The shift position will
change to N.
To shift to the Br mode, pull the shift lever to the rear along
the shift gate. Shifting to Br mode is only possible when the
shift position D is selected.
When shifting from P to N, D or R, from D to R, or from R to D,
ensure that the brake pedal is being depressed and that the veh icle
is stationary.
Shift position indicator
When selecting a shift position, make sure that the shift posit ion
has been changed to the desired po sition by checking the shift
