Fuel-fired Heater (if equipped)
This fuel-fired heater supplies addi-
tional heat to the interior compart-
ment with a low fuel consumption to
compensate the heat provided by
engine alone.
A cleaning process of the fuel-fired
heater will be performed automati-
cally when the heater is not operated
due to increase of coolant tempera-
ture and ignition off.
During cleaning process, supplied
fuel in the heater will be burnt com-
pletely and any smoke will be
expelled. It is a necessary process
for next operation and durability of
the heater and takes about 1~3 min-
utes.
• The following symptoms will
occur and it is normal.
- A white smoke may come out
from the fuel-fired heater
exhaust pipe during operation
of the heater. However, when
an excessive black smoke is
discharged,
the fuel-fired
heater should be inspected.
- A “buk-buk” noise from the
heater is a noise to form flame
for combustion.
- When the heater is operated at
full load, a “Wooing” noise
occurs.
- When shutting off the engine
during heater operation, a
“Wing” noise occurs to per-
form the cleaning process.
• When refueling, stop operation
of the fuel-fired heater by shut-
ting off the engine.
Climate control air filter
(if equipped)
The climate control air filter installed
behind the glove box filters the dust
or other pollutants that come into the
vehicle from the outside through the
heating and air conditioning system.
If dust or other pollutants accumulate
in the filter over a period of time, the
air flow from the air vents may
decrease, resulting in moisture accu-
mulation on the inside of the wind-
shield even when the outside (fresh)
air position is selected. If this hap-
pens, we recommend that the cli-
mate control air filter be replaced by
an authorized HYUNDAI dealer.
