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

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.

The outside ambient temperature is
displayed in the lower portion of the LCD
cluster display. The temperature will
read in Fahrenheit or Celsius depending
on the units selected in the User Settngs
menu.
Note that the temperature indicated
on the LCD display may not change
as quickly as the outside temperature
(there may be a slight delay before the
temperature changes.)
You can change the temperature unit
from the Settings menu in the Cluster.
Select:
- Setup → Unit → Temperature Unit →
°F/°C
Both the temperature unit on the cluster
LCD display and climate control screen
will change.

Information
• If the vehicle is not on level ground or
the battery power has been interrupted,
the distance to empty function may not
operate correctly.
• The distance to empty may differ
from the actual driving distance as it
is an estimate of the available driving
distance.
• The Distance to Empty indicator may
not change accurately if less than 1.5
gallons of fuel are added to the vehicle.
• The distance to empty may vary
significantly based on driving
conditions, driving habits, and
condition of the vehicle.

The average fuel economy (1) and instant
fuel economy (2) is displayed at the

Electronic Parking Brake
(EPB) warning light
This warning light illuminates:
• When you set the ignition switch or
the Engine Start/Stop button to the
ON position.
-The EPB warning light illuminates
for about 3 seconds and then goes
off.
• Whenever there is a malfunction with
the EPB.
If the EPB warning light remains
illuminated while driving, have the
vehicle inspected by an authorized
HYUNDAI dealer.
Information
The Electronic Parking Brake (EPB)
warning light may illuminate when
the Electronic Stability Control (ESC)
indicator light comes on to indicate that
the ESC is not working properly (This
does not indicate malfunction of the EPB).
AUTO HOLD indicator light
This indicator light illuminates:
• [White] When you activate the auto
hold system by pressing the AUTO
HOLD switch.
• [Green] When you stop the vehicle
completely by depressing the brake
pedal with the Auto Hold system
activated.
• [Yellow] Whenever there is a
malfunction with the Auto Hold
system.
If the AUTO HOLD indicator light
remains YELLOW while driving, have
the vehicle inspected by an authorized
HYUNDAI dealer.
For more details, refer to “Auto Hold”
section in chapter 6.
Charging system warning
light
This warning light illuminates:
When the battery is not being charged
while the engine is running. Immediately
turn OFF all electrical accessories. Try
not to use electrically operated controls,
such as the power windows. Keep the
engine running.
We recommend that you have the
vehicle inspected by an authorized
HYUNDAI dealer as soon as possible.
Engine oil pressure warning
light
If the oil pressure lowers due to
insufficient engine oil, etc., the engine oil
pressure warning light turns on and an
enhanced engine protection system that
limits the engine’s power is activated.
If this warning light turns on while
driving, drive carefully to the side of the
road and stop the vehicle, check the
engine oil level, and add if insufficient.
If the engine oil isn’t insufficient, or if
the warning light does not turn off even
after adding, we recommend to visit an
authorized HYUNDAI dealer.
Driving with the warning light on may
cause engine failure.
à When oil pressure is restored to an
optimal level, the oil pressure warning
light and the protection system that
limits engine power will turn off. Even
if the oil pressure returns to normal,
check the engine once again in a safe
place.
