Quick Reference Guide
In Case of a Crash
●If a vehicle fire occurs, leaked hydrogen gas may ignite. Stay far away from the vehicle 
and call the local fire department.
To extinguish a vehicle fire, use a large amount of water, dry chemical fire extinguisher 
(Class A, B, or C), or carbon dioxide fire extinguisher. With an inadequate amount of 
water, a fire cannot be put out completely. Never attempt to extinguish a vehicle fire 
with a small amount of water.
● If your vehicle needs to be towed, make sure it is done with all the wheels lifted using the 
flat bed equipment. If the front wheels are touching the ground, the rotating tires will 
force the electric motor to spin, which  in turn, may damage the power system, 
transmission, etc.
WARNING
If the body of the vehicle is seriously 
damaged or deformed in a crash, hydrogen 
gas may leak out from the vehicle. Keep 
flammable sources, such as a lit cigarette or 
warning flares, away from the vehicle. 2If Hydrogen Gas is Leaking  (P511)
Also, high voltage parts and/or the cables 
(orange) connecting them may be exposed 
as a result of a crash. Stay clear of these 
parts as you may be electrocuted.
If the vehicle catches fire, leaked hydrogen 
gas may ignite. Stay far away from the 
vehicle and report to the fire department 
that a vehicle containing hydrogen tanks is 
on fire.
The system is designed so that in the event 
that the vehicle catches fire, the gas inside 
the tanks will be released through the tank 
valves, thereby ensuring that pressure 
within the tanks does not build up. This gas 
is released toward the rear of the vehicle in 
a downward direction.  Do not attempt to 
extinguish the fire from behind the vehicle 
as the exiting gas may ignite into a flame.

VSA® On and Off (P 413)
● The Vehicle Stability Assist ® (VSA® ) system 
helps stabilize the vehicle during 
cornering and helps maintain traction 
while accelerating on loose or slippery 
road surfaces.
● VSA ® comes on automatically every time 
you turn on the power system.
● To partially disable or fully restore VSA ® 
function, press and ho ld the button until 
you hear a beep.
CMBSTM On and Off 
(P 435)
● When a possible collision is likely 
unavoidable, the CMBS
TM can help you to 
reduce the vehicle speed and the severity 
of the collision.
● To turn the CMBS
TM on or off, press and 
hold the button until you hear a beep.
Tire Pressure Monitoring 
System (TPMS) 
(P 415)
● Detects a change in tire conditions and 
overall dimensions due to decrease in tire 
pressures.
● The TPMS is turned on automatically 
every time you turn  on the power system.
● A calibration procedure must be 
performed when certain conditions arise.
Refueling (P 444)
aSet the power mode 
to OFF.
bPress the hydrogen 
fuel lid release 
button on the 
driver’s door to open 
the fuel lid.
cRemove the dust cap 
inside the hydrogen 
fuel lid.
dStart refueling.
Fuel requirement: Compressed hydrogen gas
Hydrogen supply pressure: 70 MP a (10,153 psig) (at 59°F [15°C])
Hydrogen filling amount
*1: Approximately 11 lbs (5 kg) (at 70 MPa)
Hydrogen tanks capacity:  37.3 US gal (141.3 L) (at 70 MPa [10,153 psig])
*1: 
A measured value when refueled at a  hydrogen station with 70 MPa (10,153 
psig) of supply pressure  complaint with the SAE  (J2601) fueling protocol.
Hydrogen Filling Station: To completely fi ll the hydrogen tank, you need to use a 
hydrogen filling station that has an H70 di spenser, which is capable of supplying 
pressures of up to 10,153 psig (70 MPa).
Refueling the vehicle is only  possible if the pressure inside the hydrogen tank of 
the vehicle does not exc eed the supply pressure of the filling station.
If you use an H35 dispenser, you will be  able to fill only half of the tank.

Why does a beeper sound 
when I walk away from the 
vehicle after I close the 
door?The beeper sounds if you move outside the walk away auto lock 
operating range before the door completely closes.

that?The Tire Pressure Monitoring Syst em (TPMS) needs attention. If 
you recently inflated or changed a tire, you have to recalibrate 
the system.

uuFor Safe Driving uImportant Safety Precautions
Safe Driving
■Pay appropriate attention to the task of driving safely
Engaging in cell phone conversation or other activities that keep you from paying 
close attention to the road, other vehicles, and pedestrians could lead to a crash. 
Remember, situations can change quickly, and  only you can decide when it is safe to 
divert some attention away from driving.
■Control your speed
Excessive speed is a major factor in crash  injuries and deaths. Generally, the higher 
the speed, the greater the risk, but serious  injuries can also occur at lower speeds. 
Never drive faster than is safe for current conditions, regardless of the maximum 
speed posted.
■Keep your vehicle  in safe condition
Having a tire blowout or a mechanical failure can be extremely hazardous.
To reduce the possibility of such problems, check your tire pressures and condition 
frequently, and perform all regul arly scheduled maintenance.
■Do not leave children unattended in the vehicle
Children left unattended in the vehicle may  be injured if they activate one or more 
of the vehicle controls. They  may also cause the vehicle to  move, resulting in a crash 
in which the children and/or another pers on(s) can be injured or killed. Also, 
depending on the ambient temperature, th e temperature of the interior may reach 
extreme levels, which can re sult in injury or death.
Even if the climate control system is  on, never leave children in the vehicle 
unattended as the climate control system can shut off at any time.
