With the recirculated air position selected, air from
passenger compartment
will be drawn through theheating system and heatedor cooled according to thefunction selected.
Outside (fresh) air position The indicator light on the
button is illuminated whenthe outside (fresh) air posi-tion is selected. With the outside (fresh) air position selected, air enters
the vehicle from outside andis heated or cooled accord-ing to the function selected.✽✽NOTICE
Prolonged operation of the heater in the
recirculated air position (without airconditioning 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
conditioning with the recirculated air
position selected will result in excessive-
ly dry air in the passenger compart-ment. WARNING
• Continued climate control system operation in the recirculated air
position may allow humidity to
increase inside the vehicle which
may fog the glass and obscure
visibility.
Do not sleep in a vehicle with the air conditioning or heating sys-
tem on. It may cause serious
harm or death due to a drop in the
oxygen level and/or body temper-
ature.
Continued climate control system operation in the recirculated air
position can cause drowsiness or
sleepiness, and loss of vehicle
control. Set the air intake controlto the outside (fresh) air position
as much as possible while driv-ing.

tion and the fan speed control to the high-est speed.
If warm air to the floor is desired while defrosting or defogging, set the mode tothe 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 bonnet and air inlet in the cowl grill to improveheater and defroster efficiency and to
reduce the probability of fogging up insideof the windshield. Manual climate control system D250101AFD

WARNING - Windshield
heating
Do not use the or position during cooling operation in
extremely humid weather. The dif-
ference between the temperature ofthe outside air and that of the wind-shield could cause the outer sur-
face 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

engine is running and remove theaccessory plug after use. Using the accessory plug for prolonged
periods of time with the engineoff could cause the battery to dis- charge.
Only use 12V electric accessories which are less than 10A in elec-
tric capacity.
Adjust the air-conditioner or heater to the lowest operatinglevel when using the power outlet.
Close the cover when not in use. Some electronic devices can cause electronic interferencewhen plugged into a vehicle’s power outlet. These devices maycause excessive audio static and

Maintenance
G030103AUN-EA
At least monthly:
Check coolant level in the enginecoolant reservoir.
Check the operation of all exterior lights, including the stoplights, turn sig-
nals and hazard warning flashers.
Check the inflation pressures of all tyres including the spare. G030104AUN-EA
At least twice a year
(i.e., every Spring and Fall) :
Check radiator, heater and air condi- tioning hoses for leaks or damage.
Check windshield washer spray and wiper operation. Clean wiper blades
with clean cloth dampened with wash-er fluid.

Temperature Mixture Percentage (volume)
Antifreeze Water
Check the condition and connections of all cooling system hoses and heater
hoses. Replace any swollen or deterio-
rated hoses.
The coolant level should be filled
between F (MAX) and L (MIN) marks on
the side of the coolant reservoir when theengine is cool. If the coolant level is low, add enough
specified coolant to provide protection
against freezing and corrosion. Bring the
level to F (MAX), but do not overfill. If fre-quent coolant refill is required, see an
authorised HYUNDAI dealer for a coolingsystem inspection.
G070101AUN-EA
Recommended engine coolant
Use only soft (de-mineralized) water in
the coolant mixture.
The engine in your vehicle has alu- minium engine parts and must be pro-
tected by an ethylene-glycol-based
coolant to prevent corrosion and freez-ing.
DO NOT USE alcohol or methanol coolant or mix them with the specifiedcoolant.
Do not use a solution that contains more than 60% antifreeze or less than
35% antifreeze, which would reduce
the effectiveness of the solution. For mixture percentage, refer to the fol-
lowing table.
