Do not use matches or a
lighter and do not smoke or
leave a lit cigarette in your
vehicle while at a gas station,
especially during refueling.
Do not over-fill or top-off your
vehicle tank, which can cause
gasoline spillage.
If a fire breaks out during refu-
eling, leave the vicinity of the
vehicle, and immediately con-
tact the manager of the gas
station and then contact the
local fire department. Follow
any safety instructions they
provide.
If pressurized fuel sprays out,
it can cover your clothes or
skin and thus subject you to
the risk of fire and burns.
Always remove the fuel cap
carefully and slowly. If the cap
is venting fuel or if you hear a
hissing sound, wait until the
condition stops before com-
pletely removing the cap.(Continued)
(Continued)
Always check that the fuel cap
is installed securely to pre-
vent fuel spillage in the event
of an accident.
(Continued)
When using an approved
portable fuel container, be
sure to place the container on
the ground prior to refueling.
Static electricity discharge
from the container can ignite
fuel vapors causing a fire.
Once refueling has begun,
contact between your bare
hand and the vehicle should
be maintained until the filling
is complete.
Use only approved portable
plastic fuel containers designed
to carry and store gasoline.
When refueling, always move
the shift lever to the P (Park)
position, set the parking
brake, and place the Engine
Start/Stop button to the OFF
position. Sparks produced by
electrical components related
to the engine can ignite fuel
vapors causing a fire.(Continued)

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 gauge
is near the "L (Low)" level, have the
vehicle be checked by an authorized
HYUNDAI dealer. Never try to start the vehicle if the
fuel tank is empty. In this condi-
tion, the engine cannot charge the
high voltage battery of the hybrid
system. If you try to start the vehi-
cle when the fuel is empty, the
high voltage battery will become
discharged and be damaged.
Plug-in hybrid mode indicator
CD (Charge Depleting, Electric)
mode : The high-voltage (hybrid)
battery is used to drive the vehicle.
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.
