Air conditioning system operation tips
If the vehicle has been parked in direct
sunlight during hot weather, open the
windows for a short time to let the hot
air inside the vehicle escape.
To help reduce moisture inside of win- dows on rainy or humid days, decrease
the humidity inside the vehicle by oper-ating the air conditioning system.
During air conditioning system opera- tion, you may occasionally notice aslight change in engine speed as the
air conditioning compressor cycles.
This is a normal system operation
characteristic.
Use the air conditioning system every month if only for a few minutes to
ensure maximum system perform-
ance.
When using the air conditioning sys- tem, you may notice clear water drip-
ping (or even puddling) on the ground
under the passenger side of the vehi-
cle. This is a normal system operation
characteristic.
Operating the air conditioning system in the recirculated air position does
provide maximum cooling, however,
continual operation in this mode may
cause the air inside the vehicle to
become stale. Climate control air filter The climate control air filter installed
behind the glove box filters the dust or
other pollutants that come into the vehi-cle 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 accumulation on the inside of
the windshield even when the outside
(fresh) air position is selected. If this hap-
pens, have the climate control air filter
replaced by an authorised Hyundai deal-
er.

CAUTION
Replace the filter every 15,000 km
or once a year.
If the car is being driven in severeconditions such as dusty, roughroads, more frequent climate con-
trol air filter inspections and changes are required.
When the air flow rate is sudden- ly decreased, the system shouldbe checked at an authorised deal-
er.

For maximum defrosting, set the temper-
ature control to the extreme right/hot posi-
tion and the fan speed control to thehighest 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
To defog inside windshield
1. Select any fan speed except 0 posi-
tion.
2. Select desired temperature.
3. Select the or position.
4. The outside (fresh) air and air condi- tioning will be selected automatically.
If the air-conditioning and outside (fresh) air position are not selected automatical-
ly, press the corresponding button manu-
ally.
To defrost outside windshield
1. Set the fan speed to the highest (extreme right) position.
2. Set the temperature to the extreme hot position.
3. Select the position.
4. The outside (fresh) air and air condi- tioning will be selected automatically.

Do not use the or positionduring cooling operation inextremely 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 thiscase, set the mode selection knob
or button to the position andfan speed control knob or button tothe lower speed.

CAUTION
Only use the power outlet when
the engine is running. The use ofthis outlet with the engine notrunning may cause the battery to
be discharged.
Only use 12V electric accessories which are less than 10A in elec-tric capacity.
Adjust the air-conditioner or heater to the lowest operating
level 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 malfunctions in other electronicsystems or devices used in your
vehicle.

CAUTION IN USING
USB DEVICE
To use an external USB device, make sure the device is notmounted when starting up the
vehicle and mount the deviceafter starting up.
If you start the vehicle when the USB device is mounted, it maydamage the USB device. (USB is
not ESA)
If the vehicle is started up or turned off while the external USBdevice is connected, the external
USB device may not work.
It may not play inauthentic MP3 or WMA files.
1) It can only play MP3 files with the compression rate between8Kbps~320Kbps.
2) It can only play WMA music files with the compression ratebetween 8Kbps~320Kbps.
Take cautions for static electricity when mounting or dismountingthe external USB device.
An encoded MP3 player is not recognizable.
(Continued)
(Continued) Depending on the condition of the external USB device, the con-nected external USB device can
be unrecognizable.
When the formatted byte/sector setting of External USB devices isnot either 512BYTE or 2048BYTE,
then the device will not be recog-nized.
Use only a USB device formatted to FAT 12/16/32.
USB devices without USB I/F authentication may not be recog-nizable.
Make sure the USB connection terminal does not come in contactwith a human body or any object.
If you repeat mounting or dis- mounting USB device in a shortperiod of time, it may break thedevice.
You might hear a strange noise when mounting or dismounting aUSB device.
(Continued)(Continued) If you dismount the external USB device during playback in USBmode, the external USB device can
be damaged or malfunction.Therefore, mount the external USBdevice when the engine is turned
off or in another mode.
Depending on the type and capac- ity of the external USB device orthe type of the files stored in the
device, there is a difference in thetime taken for recognition of the device, but this is not an indicatorof trouble and you only have to
wait.
Do not use the USB device for other purposes than playing music files.
Use of USB accessories such as recharger or heater using USB I/Fmay lower performance or cause
trouble.
If you use devices such as a USB hub you purchased separately,the vehicle’s audio system may
not recognize the USB device. Connect the USB device directlyto the multimedia terminal of the vehicle.

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 and L marks on the side of the
coolant reservoir when the engine iscool.
If the coolant level is low, add enough
specified coolant to provide protection
against freezing and corrosion. Bring the
level to F, but do not overfill. If frequent
additions are required, see an authorised
Hyundai dealer for a cooling systeminspection.
Recommended engine coolant
Use only soft (de-mineralised) water in
the coolant mixture.
The engine in your vehicle has alu- minum 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.
Changing the coolant
Have coolant changed by an authorised Hyundai dealer according to theMaintenance Schedule at the beginningof this section.
