Fuel Filter Warning Light
(for diesel engine)
This warning light illuminates:
• When water has accumulated inside
the fuel filter.
In this case, remove the water from
the fuel filter.
For more details, refer to “Fuel Filter” in
chapter 9.
NOTICE
• When the Fuel Filter Warning Light
illuminates, engine power (vehicle
speed & idle speed) may decrease.
• If you keep driving with the warning
light on, engine parts (injector,
common rail, high pressure fuel
pump) may be damaged. If this
occurs, we recommend that you
have the vehicle inspected by an
authorized HYUNDAI dealer as soon
as possible.
Exhaust System (DPF)
Warning Light (for diesel
engine, if equipped)
This warning light illuminates:
• When there is a malfunction with the
Diesel Particulate Filter (DPF) system.
When this warning light illuminates, it
may turn off after driving the vehicle:
- at more than 60 km/h (37 mph), or
- above 2nd gear with 1500 ~ 2500
engine rpm for a certain time (for
about 25 minutes).
If this warning light blinks in spite of
the procedure, we recommend that you
have the DPF system checked by an
authorized HYUNDAI dealer.
NOTICE
If you continue to drive with the DPF
warning light blinking for a long time,
the DPF system can be damaged and
fuel consumption can worsen.

Average fuel consumption (if
equipped) (l/100 km or MPG)
This mode calculates the average fuel
consumption from the total fuel used
and the distance since the last average
consumption reset. The total fuel used
is calculated from the fuel consumption
input. For an accurate calculation, drive
more than 300 m (0.18 miles).
Pressing the RESET button for more
than 1 second, when the average fuel
consumption is being displayed, clears
the average fuel consumption to zero
(--.-).
OQXI049121OQXI049121
Instant fuel consumption (if
equipped) (l/100 km or MPG)
This mode calculates the instant fuel
consumption of the last few seconds.

NOTICE
• 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 trip computer may not register
additional fuel if less than 6 liters
(1.6 gallons) of fuel are added to the
vehicle.
• The fuel consumption and distance to
empty may vary significantly based
on driving conditions, driving habits,
and condition of the vehicle.
• The distance to empty value is an
estimate of the available driving
distance. This may differ from the
actual driving distance available.
OQXI049122OQXI049122
Average speed (km/h or MPH)
This mode calculates the average speed
of the vehicle since the last average
speed reset.
Even if the vehicle is not in motion, the
average speed keeps going while the
engine is running.
Pressing the RESET button for more
than 1 second, when the average speed
is being displayed, clears the average
speed to zero (---).

Average Fuel Economy (1)
• The average fuel economy is
calculated by the total driving distance
and fuel consumption since the last
average fuel economy reset.
• The average fuel economy can be
reset both manually and automatically.Manual reset
To clear the average fuel economy
manually, press the [OK] button on the
steering wheel for more than 1 second
when the average fuel economy is
displayed.
Automatic reset
To automatically reset the average fuel
economy after refueling, select the “Fuel
Econ. Reset” mode in the User Settings
menu on the LCD display.
- After ignition: The average fuel
economy will reset automatically
whenever it has passed 4 hours after
turning OFF the engine.
- After refueling: The average fuel
economy will reset automatically
when driving speed exceeds 1 km/h,
after adding 6 liters (1.6 gallons) of fuel
or more.
i Information
The average fuel economy may be
inaccurate, when the vehicle drives
shorter than 300 meters (0.19 miles) after
turning ON the Engine Start/Stop button.
Instant Fuel Economy (2)
• This mode displays the instant fuel
economy during the last few seconds
when the vehicle speed is more than
10 km/h (6.2 mph).

Diesel particulate filter (DPF)
(if equipped)
The Diesel Particulate Filter (DPF)
system removes the soot in the exhaust
gas. Unlike a disposable air filter,
the DPF system automatically burns
(oxidizes) and removes the accumulated
soot according to the driving condition.
In order words, the active burning by
engine control system and high exhaust
gas temperature caused by normal/high
diving condition burns and removes the
accumulated soot.
However, if the vehicle continues to
be driven at repeated short distance
or driven at low speed for a long time,
the accumulated soot may not be
automatically removed because of low
exhaust gas temperature. More than
a certain amount of soot deposited,
the malfunction indicator light (
)
illuminates.
When the malfunction indicator light
illuminates, it may turn-off after driving
the vehicle at more than 60km/h (37
mph) or at more than second gear with
1500~2500 engine rpm for a certain time
(for about 25 minutes).
If the malfunction indicator light (
) is not turn-off or blinking continuesly
in spite of the procedure, visit a
professional workshop and check the
DPF system. HYUNDAI recommends
to visit an authorized HYUNDAI dealer/
service partner.
If you continue to drive with the
malfunction indicator light blinking for
a long time, the DPF system can be
damaged and fuel consumption can be
worsen and the engine durability can be
worsen by oil dilution.
CAUTION
Diesel Fuel (if equipped with DPF)
We recommend you to use only the
regulated diesel fuels, when your
vehicle is equipped with the DPF
system.
When you use other diesel fuels, which
is high in sulfurs (above 50 ppm) or
contains unspecified additives, it may
damage the DPF system and cause the
white smoke emission.
Lean NOx Trap (if equipped)
The Lean NOx Trap (LNT) system
removes the nitrogen oxide in the
exhaust gas. The smell can occur in the
exhaust gas depending on the quality
of the fuel and it can degrade NOx
reduction performance, please use the
regulated automotive diesel fuel.
