When a certain level of impact from an accident is detected, the fuel
cell system is shut down and the system shuts out the high voltage.
Also, the fuel supply is stopped from the hydrogen tank valves. If the
emergency shut off system activates, your vehicle will not rest art. To
restart the fuel cell system, contact your Toyota dealer.
A message is automatically displ ayed when a malfunction occurs in
the fuel cell system or an im proper operation is attempted.
If a warning message is shown on
the multi-information display, read
the message and follow the
instructions. ( P. 376)
Fuel cell vehicles do not have engine sounds like gasoline vehi cles.
Therefore, it makes an artificial noise at low speeds to notify pedestri-
ans and nearby vehicles that it is approaching. The sound varie s with
speed and will stop whe n the vehicle exceeds approximately 15 mp h
(25 km/h).

There is an air intake vent beside
the rear left seat for the purpose
of cooling the traction battery. If
the air intake vent is blocked, it
could lead to a reduction in trac-
tion battery output.
■If a warning light comes on, a warning message is displayed, or the
12-volt battery connection is disconnected
The fuel cell system may not be able to restart.
If the “READY” indicator does not come on, even when the start procedure is
repeated, contact your Toyota dealer.
■ If “Hydrogen Leakage Detected Visit Your Dealer” is displayed on the
multi-information display
A small amount of hydrogen gas may be leaking. Have the vehicle inspected
immediately at the nearest Toyota dealer.
■ If “FC System Shutdown due to Hydrogen Leakage Stop Your Vehicle in
a Safe Place and Contact Your Dealer” is displayed on the multi -informa-
tion display
● Hydrogen gas may be leaking.
When hydrogen gas is leaking or some other malfunction is detected:
P. 90
● The air conditioning system will shut off automatically.
■ Running out of fuel
When the vehicle has run out of fuel and the fuel cell system c annot be
started, refuel the vehicle until the low fuel level warning li ght (P. 371) turns
off before trying to restart. It may not be able to restart if the refueled amount
is too low (less than about 2.7 lb. [1.2 kg]).

Power output restriction
When the power output is restricted, the vehicle may fail to accelerate or even
decelerate, even though the accelerator pedal is depressed. If a safe driving
speed cannot be maintained, stop the vehicle in a safe place aw ay from the
traffic. This may be caused by the following conditions:
● The coolant temperature may be too high. This can be caused by driving
conditions such as repeated sudden acceleration and deceleratio n, continu-
ous driving on an incline, continuous driving at high altitudes with a high
load, etc. In such situations, the power output restriction ind icator (amber) is
displayed on the main display, “High FC Temperature Reduced Power” is
displayed on the multi-information display, and the power outpu t is
restricted. Once the coolant returns to normal temperature, the power out-
put will return to normal. ( P. 377)
● The remaining fuel may be low. After the low fuel warning indicator comes
on, the output power will be gradually restricted in order to extend the possi-
ble driving distance. Once getting to this point, the remaining driving dis-
tance possible is short. Immediately refill the vehicle with hy drogen.
● On cold days, the low fuel warning indicator comes on faster than usual and
the output power is restricted.
■ Vehicle proximity notification system
In the following cases, the vehicle proximity notification syst em may be diffi-
cult to hear for people around.
● In very noisy areas
● In wind or rain
Also, because the vehicle proximity notification system is loca ted in the front
of the vehicle, it may be more difficult to hear from the rear of the vehicle
compared to the front.
■ Electromagnetic waves (EMF)
●High-voltage parts and cables in fuel cell vehicles have an ele ctromagnetic
shielding configuration, and therefore emit approximately the s ame amount
of electromagnetic waves as conventional gasoline-powered vehicles or
home electronic appliances.
● Your vehicle may cause sound interference in some third party-p roduced
radio parts.
■ Traction battery
The traction battery has a limited service life. The lifespan of the traction bat-
tery can change according to driving style and driving conditio ns.

Hydrogen Gas Characteristics
●Hydrogen gas ignites more easily than gasoline. However, it is lighter than
air and disperses quickly. So even if hydrogen were to leak from the system,
it would quickly dilute until it is no longer flammable.
● As with gasoline and natural gas, hydrogen gas is not dangerous if it is han-
dled properly. Thoroughly read and understand the characteristi cs shown in
the table below.

Basic concepts of hydrogen safety
●Prevent leakage
The pipe joints of the hydrogen pipelines are designed to preve nt leaks.
The joints are checked for gas leakage at every official vehicle inspection.
● Detect to stop leakage
• The vehicle is equipped with hydrogen detectors. If the hydrog en detec-
tors detect a leak, the hydrogen tank valves automatically clos e to pre-
vent more hydrogen from escaping.
• The vehicle is equipped with a collision sensor. If the collis ion sensor
detects a collision, the hydrogen tank valves automatically clo se to pre-
vent hydrogen gas from leaking from any damaged components.
● Disperse the leaked hydrogen gas
The hydrogen tanks and pipelines are located outside of the passenger
compartment, so any leaked gas will disperse into the atmospher e by
design.
● Eliminate sources of fire
No source of fire is located near the hydrogen pipelines by des ign.
WARNING
■Hydrogen-related components
● Never alter, customize, or disassemble any hydrogen-related par ts.
● The hydrogen tanks, fuel cell stack, hydrogen pipelines, and co nnecting
components are filled with hydrogen gas. Do not remove or disassemble
these parts. Doing so can cause a hydrogen gas leak, resulting in fire or
explosion of the vehicle, which may result in death or serious injury.
■ When hydrogen gas leak or other malfunction is detected
● If you notice gas leaking noises or any other malfunction, imme diately stop
the vehicle in a safe, well-ventilated place.
● If a warning message is shown on the multi-information display, immedi-
ately stop the vehicle in a safe, well-ventilated place.
● If a large amount of hydrogen gas leaking is noticed, turn off the power
switch, exit the vehicle, and stay far away from it. Display wa rning signs
and keep sources of fire away from the vehicle. If possible, get assistance.
When the above is done, immediately contact your Toyota dealer.

WARNING
■Precautions in case of an accident
In the event of an accident, observe the following precautions. Failure to do
so can cause fire or electric shocks, resulting in death or ser ious injury.
● Stop the vehicle in a safe place to prevent subsequent accident s. Shift the
shift position to P and apply the parking brake.
● Check for hydrogen gas leakage.
Hydrogen leaks will cause a warning message to be shown on the multi-
information display. Larger leaks may also be audible.
● If a large amount of hydrogen gas leaking is noticed, turn off the power
switch, exit the vehicle, and stay far away from it. Display wa rning signs
and keep sources of fire away from the vehicle. If possible, get assistance.
When the above is done, immediately contact your Toyota dealer.
● Do not touch the high-voltage parts, cables (orange), or connec tors.
● If electric wires are exposed inside or outside your vehicle, an electric
shock may occur. Never touch exposed electric wires.
● If a fluid leak occurs, do not touch the fluid as it may be the strong alkaline
electrolyte from the traction battery. If it comes into contact with your skin
or eyes, wash it off immediately with a large amount of water, and seek
immediate medical attention.
● If a vehicle fire occurs, extinguish it with a Class A, B, or C fire extin-
guisher. If using water, apply a large amount from a hydrant.
● In case of a vehicle fire, the hydrogen gas in the hydrogen tan ks is
released via the hydrogen tank valves toward the rear of the ve hicle
angled downward, in order to reduce the damage to the hydrogen tanks.
Keep away from the vehicle.
● If your vehicle needs to be towed, do so with the front wheels lifted. If the
wheels are touching the ground, the electric motor (traction mo tor) may
continue to generate electricity. This may cause a fire.
