Foreword
HEV (HYBRID ELECTRIC VEHICLE) SYSTEM
The HYUNDAI Hybrid Electric Vehicle (HEV) uses both the gasoline engine and the
electric motor for power. The electric motor is run by a high-voltage HEV battery.
Depending on the driving conditions, the HEV computer selectively operates between
the engine and the electric motor or even both at the same time.
Fuel efficiency increases when the engine is at idle, or when the vehicle is driven by the
electric motor with the HEV battery.
The HEV battery charge must be maintained, so at times the engine will come on even
at idle to act as a generator. Charging also occurs when decelerating or by regenerative
braking.

Safety System
3-48
For example, if a child restraint of the
type specified in the regulations is on the
seat, the occupant classification sensor
can detect it and cause the air bag to
turn OFF.
Front passenger seat adult occupants
who are properly seated and wearing the
seat belt properly, should not cause the
passenger air bag to be automatically
turned OFF. For small adults it may be
turned OFF, however, if the occupant
does not sit in the seat properly (for
example, by not sitting upright, by sitting
on the edge of the seat, or by otherwise
being out of position), this could cause
the sensor to turn the air bag OFF.
You will find the “PASSENGER AIR BAG
OFF” indicator on the center fascia
panel. This system detects the conditions
1-4 in the following table and activates or
deactivates the front passenger air bag
based on these conditions.
Always be sure that you and all vehicle
occupants are seated properly and
wearing the seat belt properly for the
most effective protection by the air bag
and the seat belt.The OCS may not function properly if the
passenger takes actions which can affect
the classification system. These include:
•
Failing to sit in an upright position.
• Leaning against the door or center
console.
• Sitting towards the sides of the front
of the seat.
• Putting their legs on the dashboard or
resting them on other locations which
reduce the passenger weight on the
front seat.
• Wearing the seat belt improperly.
• Reclining the seatback.
• Wearing a thick cloth like ski wear or
hip protection wear.
• Putting an additional thick cushion on
the seat.
• Putting electrical devices (e.g.
notebook, satellite radio) on the seat
with inverter charging.
