HYDROGEN GAS DETECTION SENSORS
There are four hydrogen gas detectors located in the vehicle. If one of
these sensors detects a leak while driving, the hydrogen gas leak
warning lamp will illuminate on the cluster display. The sensors will
trigger at concentrations below the minimum flammability limit of
hydrogen. However, when the sensor is triggered, the hydrogen fuel cell
system will be shut down. At that time, the vehicle will revert to “EV mode”,
which will allow the vehicle to be driven solely on the high voltage battery
system. EV mode is limited to only about 1 mile of driving range,
therefore it is important to pull over to the side of the road as soon as it is
reasonably safe to do so. When the vehicle has stopped, turn OFF the
ignition and contact an authorized Hyundai Tucson Fuel Cell dealer
immediately.

SAFETY PLUG
A safety plug located in the rear trunk is
applied to be able to disconnect the high
voltage system from the fuel cell stack.
IMPORTANT :This equipment is for
trained personnel only.
DANGER
There are special procedures required for
removing the safety plug from the vehicle.
Do not attempt to remove the safety plug
by yourself. This device is for a trained
service technician at an authorized
Hyundai Fuel Cell dealer or for first
responders in the event of an emergency
with the vehicle. Emergency responders
have received special instructions on how
to disconnect the high voltage system
using the safety plug.

VIRTUAL ENGINE SOUND SYSTEM (VESS)
Because the Tucson Fuel Cell vehicle is an electric vehicle, it is very
quiet and produces no audible noise from the engine compartment when
the vehicle is in motion. In order to alert pedestrians that a vehicle is
near, a Virtual Engine Sound System (VESS) is implemented.
The Tucson Fuel Cell vehicle emits a warning chime to pedestrians when
the vehicle is operating in the forward direction at low speeds (from 1 to
13 mph), and whenever the vehicle is shifted into reverse.
