Quick Reference Guide
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.

Compressed hydrogen gas
1 Refueling
NOTICE
If improper hydrogen gas is us ed, the FC stack will be 
damaged. Always refuel  at authorized hydrogen 
filling stations.
2 Refer to the Navigation System Manual
Hydrogen gas is colorless, odorless, very light and 
flammable. Also, its burni ng flame is difficult to 
detect by sight.
3WARNING
When refueling hydrogen gas, keep 
sources of fire, such as  a lit cigarette, away 
from the vehicle. As hydrogen gas is highly 
flammable, it may caus e a fire or explosion.
Be sure to turn the pow er system to OFF to 
stop the FC stack operation.
