5. Remove any dust on the charging
connector and charging inlet.
6. Hold the charging connector han- dle. Then, insert it into the charg-
ing inlet, until you hear a click
sound. If it is not fully connected, a
bad connection between the
charging connector and the charg-
ing terminals may cause a fire. 7. Check if the charging cable con-
nection indicator of the high volt-
age battery in the instrument clus-
ter is turned ON.
Charging does not occur when the
indicator is OFF. When the charg-
ing connector is not connected
properly, reconnect the charging
cable to charge.
Information
• The charging is in progress only with the shift lever is in P (Park).
Charging the battery with the
Engine Start/Stop button in the
ACC position is possible. However,
it may discharge the 12-V battery.
Thus, if possible, charge the battery
with the Engine Start/Stop button in
the OFF position.
• Moving the shift lever from P (Park) to R (Reverse)/N(Neutral)/D (Drive)
stops the charging process.
To restart the charging process,
move the shift lever to P (Park),
press the Engine Start/Stop button
to the OFF position, and disconnect
the charging cable. Then, connect
the charging cable.

you cannot start the vehicle.
4. Depress the brake pedal.
5. Press the Engine Start/Stop but- ton. If the hybrid system starts, the
" " indicator will come on and a
double chime can be heard.
Whether the engine is cold or warm, it should be started without
depressing the accelerator.
After following the start proce-
dures, " " indicator on the
instrument cluster will turn on.
For more information, please
check Chapter 5. ECONOMICAL and SAFE OPERA-
TION of Hybrid system
Drive smoothly. Accelerate at a
moderate rate and maintain a
steady cruising speed. Do not
make "jack-rabbit" starts. Do not
race between stoplights.
Avoid heavy traffic whenever pos-
sible. Always maintain a safe dis-
tance from other vehicles so you
can avoid unnecessary braking.
This also reduces brake wear out.
The regenerative brake generates energy when the vehicle deceler-
ates.
When the hybrid battery power is low, the hybrid system automatical-
ly recharges the hybrid battery.
When the engine is running with the shift lever in N (Neutral), the
hybrid system cannot generate
electricity. The hybrid battery can-
not recharge with the shift lever in N
(Neutral).
Information
In the hybrid system, the engine auto-
matically runs and stops. When the
hybrid system operates, the " "
indicator is illuminated.
In the following situation, the engine
may operate automatically.
- When the engine is ready to run
- When the hybrid battery is beingcharged
- Depending on the temperature con- dition of the hybrid battery
i
To avoid serious injury, turn off
hybrid system and be sure " "
indicator is off before working
under hood. Engine may start
unexpectedly.
WARNING

H25
According to the hybrid system
gauge area, the "EV" indicator comes
on or off.
- "EV" indicator ON : Vehicle is drivenusing the electric motor or the
gasoline engine is stopped.
- "EV" indicator OFF : Vehicle is driv- en using the gasoline engine.Hybrid Battery SOC (State of Charge) Gauge
This gauge indicates the remaining
hybrid battery power. If the SOC is
near the "L (Low)" level, the vehicle
automatically operates the engine to
charge the battery. However, if the Service Indicator ( )
and Malfunction Indicator Lamp (MIL)
( ) turn on when the SOC (State of
charge) gauge is near the "L (Low)"
level, have the vehicle checked by an
authorized HYUNDAI dealer.
