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.

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-
cle as soon as it is safe to do so.
In the event of an emergency, such as if it becomes impossible to stop the
vehicle in the normal way: →P. 361
● Do not adjust the positions of the steering wheel, the seat, or the inside or
outside rear view mirrors while driving.
Doing so may result in a loss of vehicle control.
● Always check that all passengers’ arms, heads or other parts of their body
are not outside the vehicle.

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. ( →P. 179)

WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury.
■If you hear a squealing or scrapi ng 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.
■ 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 shift the shift position to P, set the parking brake. Failure to do so
may cause the vehicle to move or the vehicle may accelerate suddenly if
the accelerator pedal is accidentally depressed.

■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.
*1
• When an attempt is made to select the R position by moving the shift
lever when the vehicle is moving forward.
*2
• When an attempt is made to select the D position by moving the shiftlever when the vehicle is moving in reverse.
*3
• When an attempt is made to change the shift position from R to Br modeby moving the shift lever.
*1: Shift position may be changed to P when driving at extremely low speeds.
*2: Shift position may be changed to R when driving at low speeds.
*3: Shift position may be changed to D when driving at low speeds.
■ Br mode
Depending on the condition of the traction battery, Br mode may not be avail-
able.
In that case, a message is displayed on the multi-information display.
■ Sounds when in Br mode
→P. 8 0
■ Restraining sudden star t (Drive-Start Control)
→P. 159
■ Reverse warning buzzer
When shifting into R, a buzzer will sound to inform the driver that the shift
position is in R.
