FCEV : Fuel Cell Electric Vehicle

H11
How to Stop the Vehicle
1. Hold down the brake pedal while
the vehicle is parked.
2. While depressing the brake pedal,
shift to P (Park).
3. While depressing the brake pedal,
engage the parking brake.
4. While depressing the brake pedal,
press the Power button and turn
off the vehicle.
5. Check if the " " indicator is
turned OFF on the instrument
cluster.
When the " " indicator is ON
and the gear is in a position other
than P (Park), the driver can acci-
dently depress the accelerator
pedal, causing the vehicle to move
unexpectedly.
Virtual Engine Sound System
The Virtual Engine Sound System
generates engine sound for pedestri-
ans to hear vehicle sound because
there is no sound while the FCEV
vehicle is operating.
• If the vehicle is in the ready ( )
mode and the gear is not in P
(Park),
When the gear is shifted to R
(Reverse), an additional warning
sound will be heard.
•The vehicle is much quieter
while driving than a conven-
tional gasoline-powered vehi-
cle. Be aware of your sur-
roundings and always drive
safely.
After you park the vehicle or
while you are waiting at a traf-
fic light, check whether there
are children or obstacles
around the vehicle.
Check if there is something
behind the vehicle when driv-
ing in reverse. Pedestrians
may not hear the sound of the
vehicle.

5. Why is there an engine noise at low
speeds, even though there is no engine?The noise is generated from the air compressor and cooling pump
working to supply air to the fuel cell or it's from Virtual Engine
Sound System (VESS).
6. When turning on and off the vehicle in
cold weather, there's a loud noise. Is this
noise cause for concern?
When you turn on the vehicle or turn off the vehicle in cold weather,
the air compressor removes the generated water inside the fuel cell
system and the noise is generated during this process, which is nor-
mal. In this case, certain amount of water may drain through the
vehicle bottom and exhaust pipe.
7. Why does a noise emanate when the
vehicle moves in reverse?
Normally, the noise is a result of the Virtual Engine Sound System
(VESS) working when the FCEV runs at low velocity (1~12 mph
(1~20 km/h)) after shifting to D or N. However, when shifting to R,
the VESS operates immediately, regardless of vehicle speed. In
addition, a separate warning chime will sound to have the pedestri-
an aware of the approaching vehicle.
8. The FCEV is equipped with a reduction
gear but no transmission. What makes it
different from standard vehicles?
The transmission of standard vehicles delivers power as conditions
require via multiple transmission gears. However, the reduction gear
of the FCEV is designed to deliver power by reducing the motor's
RPM as operating conditions dictate, or to move backwards by
reversing the rotational direction of the shaft.
