Safety system of your vehicle
Each time you push the switch, the
temperature setting of the seat is
changed as follows :
The seat warmer defaults to the OFF
position whenever the Engine Start/
Stop button is placed in the ON posi-
tion.
Information
With the seat warmer switch in the
ON position, the heating system in the
seat turns off or on automatically
depending on the seat temperature.
Battery Cooling Duct
The high voltage battery cooling duct
is located on the left side of the rear
seats. The cooling duct cools down
the high voltage battery.When the high voltage battery cool-
ing duct is blocked, the high voltage
battery may be overheated. Do not
obstruct the cooling duct with any
other objects.

Closing the fuel filler door
1. To install the fuel tank cap, turn it
clockwise until it "clicks" one time.
2. Close the fuel filler door until it is
latched securely.
Gasoline is highly flammable
and explosive. Failure to follow
these guidelines may result in
SERIOUS INJURY or DEATH:
Read and follow all warnings
posted at the gas station.
Before refueling, note the
location of the Emergency
Gasoline Shut-Off, if available,
at the gas station.
Before touching the fuel noz-
zle, you should eliminate the
potential build-up of static
electricity by touching a metal
part of the vehicle, a safe dis-
tance away from the fuel filler
neck, nozzle, or other gas
source, with your bare hand.
(Continued)
WARNING
(Continued)
Do not use cellular phones
while refueling. Electric cur-
rent and/or electronic interfer-
ence from cellular phones can
potentially ignite fuel vapors
and cause a fire.
Do not get back into a vehicle
once you have begun refuel-
ing. You can generate a build-
up of static electricity by
touching, rubbing or sliding
against any item or fabric
capable of producing static
electricity. Static electricity
discharge can ignite fuel
vapors causing a fire. If you
must re-enter the vehicle, you
should once again eliminate
potentially dangerous static
electricity discharge by touch-
ing a metal part of the vehicle,
away from the fuel filler neck,
nozzle or other gasoline
source, with your bare hand.
(Continued)
Add fuel into the fuel tank
within 20 minutes after open-
ing the fuel filler door. After 20
minutes, the fuel tank may
shut off, causing fuel to over-
flow. In this case, re-press the
fuel filler door opening but-
ton.
Do not leave the fuel filler
door opened for an extended
period of time. It may dis-
charge the battery.
Close the fuel filler door after
fueling the vehicle. If you start
the vehicle with the fuel filler
door opened, the message,
"Check fuel door", illuminates
on the LCD display.
Avoid refueling the vehicle
while charging the (high-volt-
age) hybrid battery. It may
cause a fire or an explosion
due to static electricity.

Avoid driving with an extremely
low fuel level. Running out of fuel
could cause the engine to misfire
damaging the catalytic converter.
Battery State of Charge (SOC)
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.
❈The actual cluster in the vehicle
may differ from the illustration.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.

Range
The range is the estimated distance
the vehicle can be driven with the
remaining fuel in the fuel tank
(Gasoline/Petrol) and high-voltage
(hybrid) battery (Electric).
If the estimated distance is below 1
mile (1 km), the trip computer will
display "---" as the range.
Information
• If the vehicle is not on level ground
or the battery power has been inter-
rupted, the range function may not
operate correctly.
• The range may differ from the actu-
al driving distance as it is an esti-
mate of the available driving dis-
tance.
• The trip computer may not register
additional fuel if less than 2 gallon (6
liters) of fuel are added to the vehicle.
• The range may vary significantly
based on driving conditions, driving
habits, and condition of the vehicle.
