Sounds Unique to the Fuel Cell Vehicle
When you first start driving this vehicle, you likely will hear some unfamiliar sounds, particularly when you first turn on the power system,
while driving, and just after parking. Some of these sounds are unique to this vehicle’s powertrain, fuel, and climate control systems; others
are similar to sounds generated by conventional automobiles that typically are masked by louder noises absent from a vehicle of this design.
These sounds are not a cause for concern, and you will soon recognize them as normal and thus be able to detect any new or unus ual noise
should one develop.
Certain sounds associated with your vehicle may be caused by:
● Pressurized intake air being released through the rear of the vehicle.
u This can happen if the accelerator is released suddenly when the vehicle is under a heavy load, such as when climbing a hill.
● The power system warming up.
u This sound is particularly loud when temperat ures are extremely low (below –4°F [–20°C]).
● Hydrogen gas flowing through the fuel line during refueling.

What to Do If
Why do I hear an operating
noise when applying the
brakes?This can occur when the ABS activates and does not indicate a
problem. Apply firm, steady pressure on the brake pedal. Never
pump the brake pedal.
2Anti-lock Brake System (ABS) (P409)
The rear door cannot be
opened from inside the
vehicle. Why?Check if the childproof lock is in
the lock position. If so, open the
rear door with the outside door
handle.
To cancel this function, slide the
lever up to the unlock position.
Why do the doors lock
after I unlocked the doors?If you do not open the doors within 30 seconds, the doors are
relocked automatically for security.
Why does the beeper
sound when I open the
driver’s door?The beeper sounds when:
●The power mode is in ACCESSORY.
●The exterior lights are left on.

uuAirbags uFront Airbags (SRS)
Safe Driving
■When front airbags should not deploy
Minor frontal crashes: Front airbags were designed to supplement seat belts and
help save lives, not to prevent minor scrapes, or even broken bones that might occur
during a less than moderate-to-severe frontal crash.
Side impacts: Front airbags can provide protection when a sudden deceleration
causes a driver or front passenger to move towards the front of the vehicle. Side
airbags and side curtain airbag s have been specifically designed to help reduce the
severity of injuries that can occur durin g a moderate-to-severe side impact which
can cause the driver or passenger to move towards the side of the vehicle.
Rear impacts: Head restraints and seat belts are your best protection during a rear
impact. Front airbags cannot provide any si gnificant protection and are not designed
to deploy in such collisions.
Rollovers: In a rollover, your best form of protection is a seat belt or, if your vehicle
is equipped with a rollover sensor, both a se at belt and a side curtain airbag. Front
airbags, however, are not designed to deploy in a rollover as they would provide
little if any protection.
■When front airbags deploy with little or no visible damage
Because the airbag system senses sudden deceleration, a strong impact to the
vehicle framework or suspension might caus e one or more of the airbags to deploy.
Examples include running into a curb, the edge of a hole, or other low fixed object
that causes a sudden deceleration in th e vehicle chassis. Since the impact is
underneath the vehicle, damage may not be readily apparent.
■When front airbags may not deploy, even though exterior damage
appears severe
Since crushable body parts absorb crash energy during an impact, the amount of
visible damage does not always indicate proper airbag operation. In fact, some
collisions can result in severe damage but no airbag deployment because the airbags
would not have been needed or would not have provided protection even if they
had deployed.

Safe Driving
■When driver’s knee airbag deploy s with little or no visible damage

that causes a sudden deceleration in th e vehicle chassis. Since the impact is

uuAirbags uSide Airbags
Safe Driving
■When a side airbag deploys with little or no visible damage
Because the airbag system senses sudden acceleration, a strong impact to the side
of the vehicle’s framework can cause a side airbag to deploy. In such cases, there
may be little or no damage, but the side impact sensors detected a severe enough
impact to deploy the airbag.
■When a side airbag may not deploy, even though visible damage appears
severe
It is possible for a side airbag to not deploy during an impact that results in
apparently severe damage. This can occur when the point of impact was toward the
far front or rear of the vehicle, or when the vehicle’s crushable body parts absorbed
most of the crash energy. In either case , the side airbag would not have been
needed nor provided protection even if it had deployed.
