WARNING
If a fire occurs:
• If a small scale fire occurs, use a fire
extinguisher (ABC, BC) that is meant
for electrical fires.
If it is impossible to extinguish
the fire in the early stage, remain
a safe distance from the vehicle
and immediately call your local
fire emergency responders. Also,
advise them that a hybrid vehicle is
involved.
If the fire spreads to the high voltage
battery, large amount of water is
needed to put out the fire.
Using small amount of water or
fire extinguishers not meant for
electrical fires could cause serious
injury or death from electrical
shocks.
• Upon witnessing any sparks, gases,
flames, or fuel leakage of your
vehicle, immediately call emergency
services or contact an authorized
HYUNDAI dealer. Also, advise them
that a hybrid vehicle is involved.
WARNING
When a submersion in water occurs:
When your vehicle is flooded in water, a
high-voltage battery may cause shock
or fires. Thus, turn the hybrid system
OFF, take the key in your possession and
escape to a safe place. Never attempt
physical contact with your flooded
vehicle.
Immediately contact an authorized
HYUNDAI dealer and advise them that a
hybrid vehicle is involved.
When the Hybrid Vehicle Shuts
Off
When the high voltage battery or 12 volt
battery is discharged, or when the fuel
tank is empty, the hybrid system may
not operate while driving. When the
Hybrid system does not operate, do the
following:
1. Gradually reduce the vehicle speed.
Pull over your vehicle off the road in a
safe area.
2. Make sure the shift button is in P (Park).
3. Turn ON the hazard warning flashers.
4. Turn OFF the vehicle, and try to start the hybrid system again, while
depressing the brake pedal and
turning on the ignition switch.
5. When the hybrid system still does not operate, refer to “Jump starting”
section in chapter 8.
Before jump-starting the vehicle,
check the fuel level and the exact
procedure to jump start. For further
details, refer to “Jump starting”
section in chapter 8. When the fuel
level is low, do not attempt to drive
the vehicle only with the battery
power. The high voltage battery may
be discharged, and the hybrid system
will turn OFF.

Seats & Safety System3-8
Power adjustment (if equipped)
The front seat can be adjusted by using
the control switches located on the
outside of the seat cushion. Before
driving, adjust the seat to the proper
position so that you can easily control
the steering wheel, foot pedals and
controls on the instrument panel.
WARNING
NEVER allow children in the vehicle
unattended. The power seats are
operable when the vehicle is turned off.
NOTICE
To prevent damage to the seats:

[ Always stop adjusting the seats when
the seat has been adjusted as far
forward or rearward as possible.

[ Do not adjust the seats longer than
necessary when the vehicle is turned
off. This may result in unnecessary
battery drain.

[ Do not operate two or more seats at
the same time. This may result in an
electrical malfunction.

Hybrid battery SOC (State of Charge)
gauge
„4.2-Inch„10.25-inch
ONX4EH040008OCN7H040003
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 gauge is near
the “L (Low)” level, we recommend the
vehicle be checked by an authorized
HYUNDAI dealer.
NOTICE
Never try to start the vehicle if the fuel
tank is empty. In this condition, the
engine cannot charge the high voltage
battery of the hybrid system. If you
try to start the vehicle when the fuel
is empty, the high voltage battery will
become discharged and be damaged.

[CD (Charge Depleting, Electric)
mode : The high-voltage (hybrid)
battery is used to drive the vehicle.

[ AUTO mode : CD mode and CS mode
are selected automatically depending
on road conditions.

[ CS (Charge Sustaining, Hybrid) mode :
The high-voltage (hybrid) battery and
gasoline engine is used to drive the
vehicle.
Information
Even when the battery charging rate
is high and driving in electric mode is
possible, engine may turn on in some areas
to protect the system.
