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.
2Locking the doors and trunk (Walk away auto lock)  (P136)
Why does the beeper 
sound when I start driving?The beeper sounds when the driver and/or front passenger are 
not wearing their seat belts.
Pressing the electric 
parking brake switch does 
not release the parking 
brake. Why?Press the electric parking brake switch with the brake pedal 
depressed.
I’m seeing an amber 
indicator of a tire with an 
exclamation point. What is 
that?The Tire Pressure Monitoring Syst em (TPMS) needs attention. If 
you recently inflated or changed a tire, you have to recalibrate 
the system. 
u
TPMS Calibration (P 415)
Depressing the accelerator 
pedal does not release the 
parking brake 
automatically. Why?●Fasten the driver’s seat belt.
●Check if the transmission is in (P or (N. If so, select any other 
position.

Continued
Driving
Tire Pressure Monitoring System (TPMS)
Instead of directly measuring the pressure  in each tire, the TPMS on this vehicle 
monitors and compares the rolling radius  and rotational characteristics of each 
wheel and tire while you are driving to  determine if one or more tires are 
significantly under-inflated. This will caus e the low tire pressure/TPMS indicator to 
come on and a message to appear on  the driver information interface.
You must start TPMS calibration every time you:
• Adjust the pressure in one or more tires.
• Rotate the tires.
• Replace one or more tires.
Before calibrating the TPMS:
• Set the cold tire pressure in all four tires.
2 Checking Tires  P. 468
Make sure:
•The vehicle is at a complete stop.
• The gear position is in 
(P.
• The power mode is in ON.
■TPMS Calibration
1Tire Pressure Monitoring System (TPMS)
The system does not monitor the tires when driving 
at low speed.
Conditions such as low  ambient temperature and 
altitude change directly a ffect tire pressure and can 
trigger the low tire pressure/TPMS indicator to come on.
Tire pressure checked and inflated in:
•Warm weather can beco me under-inflated in 
colder weather.
•Cold weather can become  over-inflated in warmer 
weather.
The low tire pressure/TPMS indicator will not come 
on as a result of over inflation.
The TPMS may not function pr operly if tire type and 
size are mixed. Make sure to use the same size and 
type of tire. 2 Checking and Maintaining Tires  P. 468
The low tire pressure/TPMS indicator may come on 
with a delay or may not come on at all when:
•You rapidly accelerate, decelerate, or turn the 
steering wheel.
•You drive on snowy or slippery roads.
•Tire chains are used.
The low tire pressure/TPMS indicator may come on 
under the following conditions:
•There is a heavier and uneve n load on the tires than 
the condition at calibration.
•Tire chains are used.
