H2
Hyundai Hybrid Electric Vehicle (HEV)
uses a gasoline engine and an electric
motor for power. The electric motor is
run from a 280V high voltage HEV bat-
tery.
HEV computer decides according to
drive condition when to use engine
from when to use the electric motor or
even both at times.
Fuel is saved when the engine is not
running at idle at times or the vehicle
is driven by the electric motor from
the HEV battery.
The charge of the HEV battery has to
be maintained so at times the engine
becomes a generator which includes
when stopped at idle. Charging also
occurs when decelerating or by
regenerative braking.Display of Hybrid system
Many displays provide information about
the hybrid system, such as, ECO level
and ECO score.
Through the ECO LEVEL, the driver under-
stands the situation of economical driving.
If the driver drives the vehicle with eco-
nomical driving, the ECO LEVEL rises.
And it means the CO2 emission reduction.
In TOTAL ECO SCORE, when you get the
maximum step of ECO LEVEL, ECO sys-
tem adds the score and saves the score.Eco level display flower mode.1
When the hybrid vehicle is started, the
ECO level step 4 is displayed. If you drive
economically, ECO level will be upgrad-
ed.
- However, if you do not drive economical-
ly, the ECO level will be down-graded.

cates the left Hybrid battery power. If the

near L(Low), the vehicle should be
towed. Refer to the chapter 6.
