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 “If the 12 Volt Battery
Is Discharged” 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 “If the 12 Volt Battery
Is Discharged” 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.

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 moved as far forward or
rearward as possible.
• Do not adjust the seats for 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.
OCN7030005
Forward and rearward adjustment
To move the seat forward or rearward:
1. Push the control switch forward or
rearward.
2. Release the switch once the seat
reaches the desired position.
OCN7030006
Seatback angle
To adjust the seatback:
1. Rotate the top of control switch
forward or rearward.
2. Release the switch once the seatback
reaches the desired position.

Power gauge
OCN7H040006OCN7H040002
„„Type A„„Type B
The power gauge indicates whether the
current driving condition is fuel efficient
or not.
•
CHARGE : Shows that the energy
made by the vehicle is being
converted to electrical energy.
(Regenerated energy)
• ECO : Shows that the vehicle is being
driven in an Eco-friendly manner.
• POWER : Shows that the vehicle is
exceeding the Eco-friendly range.
Information
Accordance to the power gauge area
the“EV” indicator comes on or off.
-“EV” indicator ON : Vehicle is driven
using the electric motor or the gasoline
engine is stopped.
-“EV” indicator OFF : Vehicle is driven
using the gasoline engine.
Hybrid battery SOC (State of Charge)
gauge
OCN7H040007
OCN7H040003
„„Type A
„
„Type B
This gauge indicates the remaining
hybrid battery power. If the SOC is near
the “0 or 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 “0 or 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.
