Climate control air filter
(if equipped)
The climate control air filter installed in
your vehicle filters the dust or other pol-
lutants that come into the vehicle from
the outside through the heating and air
conditioning system. If dust or other pol-
lutants accumulate in the filter over a
period of time, the air flow from the air
vents may decrease, resulting in mois-
ture accumulation inside of the wind-
shield even when the outside (fresh) air
position is selected. If this happens, have
the climate control air filter replaced by
an authorized HYUNDAI dealer.
✽NOTICE
• Replace the filter according to the
Maintenance Schedule in section 7.
If the vehicle is being driven in severe
conditions such as dusty, rough roads,
more frequent climate control air fil-
ter inspections and changes are
required.
• When the air flow rate suddenly
decreases, the system should be
checked at an authorized HYUNDAI
dealer.
D230400APB
Checking the amount of air con-
ditioner refrigerant and compres-
sor lubricant
When the amount of refrigerant is low,
the performance of the air conditioning is
reduced. Overfilling also has a negative
impact on the air conditioning system.
Therefore, if abnormal operation is
found, have the system inspected by an
authorized HYUNDAI dealer.
✽NOTICE
It is important that the correct type and
amount of oil and refrigerant is used.
Otherwise, damage to the compressor
and abnormal system operation may
occur.

Automatic heating and air condi-
tioning
The automatic climate control system is
controlled by simply setting the desired
temperature.
The Full Automatic Temperature Control
(FATC) system automatically controls the
heating and cooling system as follows:
1. Press the AUTO button. The modes,
fan speeds, air intake and air-condi-
tioning will be controlled automatically
by setting the temperature.2. Set the temperature control knob to
the desired temperature.
If the temperature is set to the lowest
setting (Lo), the air conditioning sys-
tem will operate continuously.
3. To turn the automatic operation off,
select any button or knob of the fol-
lowing:
• Mode selection button
• Air conditioning button
• Front windshield defroster button
• Air intake control button
• Fan speed control knob
The selected function will be controlled
manually while other functions operate
automatically.
For your convenience and to improve the
effectiveness of the climate control, use
the AUTO button and set the tempera-
ture to 23°C (73°F).
Regardless of the temperature setting,
when using automatic operation, the air
conditioning system can automatically
turn on to decrease the humidity inside
the vehicle, even if the temperature is set
to warm.
✽NOTICE
Never place anything over the sensor
located on the instrument panel to
ensure better control of the heating and
cooling system.

Recirculated air position
The indicator light on the
button illuminates when the
recirculated air position is
selected.
With the recirculated air
position selected, air from
the passenger compartment
will be drawn through the
heating system and heated
or cooled according to the
function selected.
Outside (fresh) air position
The indicator light on the
button will not illuminate
when the outside (fresh) air
position is selected.
With the outside (fresh) air
position selected, air enters
the vehicle from outside and
is heated or cooled accord-
ing to the function selected.✽NOTICE
Prolonged operation of the heater in the
recirculated air position (without air
conditioning selected) may cause fog-
ging of the windshield and side windows
and the air within the passenger com-
partment may become stale.
In addition, prolonged use of the air con-
ditioning with the recirculated air posi-
tion selected, will result in excessively
dry air in the passenger compartment. WARNING
• Continuous operation of the cli-
mate control system in the recircu-
lated air position may allow humid-
ity to increase inside vehicle which
may fog the glass and obscure vis-
ibility.
• Do not sleep in a vehicle with air
conditioning or heating system on.
It may cause serious harm or death
due to a drop in the oxygen level
and/or body temperature.
• Continuous operation of the cli-
mate control system in the reciru-
clated air position can cause
drowsiness or sleepiness, and
loss of vehicle control. Set the air
intake control to the outside (fresh)
air position as much as possible
while driving.

WINDSHIELD DEFROSTING AND DEFOGGING
D250000AHM
• For maximum defrosting, set the temper-
ature control to the extreme right/hot
position and the fan speed control to the
highest speed.
• If warm air to the floor is desired while
defrosting or defogging, set the mode to
the floor-defrost position.
• Before driving, clear all snow and ice from
the windshield, rear window, outside rear
view mirrors, and all side windows.
• Clear all snow and ice from the hood and
air inlet in the cowl grill to improve heater
and defroster efficiency and to reduce the
probability of fogging up inside of the
windshield.

WARNING - Windshield
heating
Do not use the or position
during cooling operation in
extremely humid weather. The dif-
ference between the temperature of
the outside air and the windshield
could cause the outer surface of
the windshield to fog up, causing
loss of visibility. In this case, set
the mode selection knob or button
to the position and fan speed
control knob or button to the lower
speed.

tion switch must be in the ACC or ON
position.
To use the cigarette lighter, push it all the
way into its socket. When the element is
heated, the lighter will pop out to the
"ready" position.
If it is necessary to replace the cigarette
lighter, use only a genuine HYUNDAI
replacement or its approved equivalent.

Ashtray (if equipped)
To use the ashtray, open the cover.
To clean or empty the ashtray, pull it out.
INTERIOR FEATURES
OPB049111/HCAUTION
Only a genuine HYUNDAI lighter
should be used in the cigarette
lighter socket. The use of plug-in
accessories (shavers, hand-held
vacuums, and coffee pots, for
example) may damage the socket
or cause electrical failure.OPB049112/H
WARNING- Ashtray use
• Do not use the vehicle’s ashtrays
as waste receptacles.
• Putting lit cigarettes or matches
in an ashtray with other com-
bustible materials may cause fire.
WARNING
• Do not hold the lighter in after it
is already heated because it will
overheat.

Starting the diesel engine
To start the diesel engine when the
engine is cold, it has to be pre-heated
before starting the engine and then has
to be warmed up before starting to drive.
1. Make sure the parking brake is
applied.
2. Depress the clutch pedal fully and shift
the transaxle into Neutral. Keep the
clutch pedal and brake pedal
depressed while turning the ignition
switch to the start position.
3. Turn the ignition switch
to the ON position to pre-
heat the engine. Then
the glow indicator light
will illuminate.
4. If the glow indicator light goes out, turn
the ignition switch to the START posi-
tion and hold it there until the engine
starts (a maximum of 10 seconds),
then release the key.
✽ NOTICE
If the engine does not start within 10
seconds after the preheating is complet-
ed, turn the ignition key once more to
the LOCK position for 10 seconds, and
then to the ON position, in order to pre-
heat again.
✽ NOTICE - Kick down mechanism
If your vehicle is equipped with a kick
down mechanism in an accelerator
pedal,it prevents you from driving at
full throttle unintentionally by making
the driver require increased effort to
depress the accelerator pedal. However
if you depress the pedal more than
approximately 80% the vehicle can be
full throttle and the accelerator pedal
will be easier to depress.This is not a
malfunction but a normal condition.
Starting and stopping the engine for tur-
bocharger intercooler
1. Do not race or accelerate the engine
immediately after starting it.
If the engine is cold, idle it for several
seconds before sufficient lubrication is
ensured in the turbocharger unit.
2. After high speed or extended driving,
requiring a heavy engine load, idle the
engine about 1 minute before turning it
off.
This idle time will allow the tur-
bocharger to cool prior to shutting the
engine off.
CAUTION
Do not turn the engine off immedi-
ately after it has been subjected to
a heavy load. Doing so may cause
severe damage to the engine or
turbo charger unit.W-60
