2012 KIA Optima Hybrid service

H12
Service plug
This service plug (1) located in the rear
trunk as shown should always be pulled
out to disconnect and turn off the hybrid
system.
IMPORTANT: Wait 5 minutes after this
lever is disconnected to work on the
car. It is to be assured all remaining
charge in the system dissipated.
Some Special Features of the
Hybrid Vehicle.
Hybrid vehicles sound different than
gasoline engine vehicles. When the
hybrid system operates, you may hear a
sound from the hybrid battery system
behind the rear seat. If you apply the
accelerator pedal rapidly, you may hear a
sound. when you apply the brake pedal,
you may hear a sound from the regener-
ative brake system. When the hybrid sys-
tem is turned off or on, you may hear a
sound in the engine compartment. If you
depress the brake pedal repeatedly
when the hybrid system is turned on, you
may hear a sound in the engine com-
partment. None of these sounds indicate
a problem.
They are characteristics of hybrid vehi-
cles.
When the hybrid system is turned on, the
engine may run. This does not indicate a
malfunction. If the "READY" symbol is on,
the hybrid system is operating. Even if
the gasoline engine is off, you can oper-
ate the vehicle.The HEV system may emit electromag-
netic waves which can affect the per-
formance of electronic devices appli-
ances, such as laptop computers, which
are not part of the vehicle design.
If you park the vehicle for a long time, the
hybrid system will discharge. You need to
drive the vehicle several times per month
to maintain a charge.
