2003 Hyundai Grandeur air conditioning

3- 4 WHAT TO DO IN AN EMERGENCY
check for coolant leaking from the radiator, hoses or under the car. (If the air conditioning had been in use,it is normal for cold water to be draining from it when you stop).
WARNING:
While the engine is running, keep hair, hands, and clothing away frommoving parts such as the fan and drive belts to prevent injury.
5. If the water pump drive belt is bro- ken or engine coolant is leaking out, stop the engine immediately and call the nearest Hyundai dealer for assistance.
WARNING:
Do not remove the radiator cap whenthe engine is hot. This can allowcoolant to be blown out of the open- ing and cause serious burns.
D030A01A-AAT IF THE ENGINE OVERHEATS If your temperature gauge indicates overheating, you experience a loss ofpower, or hear loud pinging or knock- ing, the engine is probably too hot. If this happens to you, you should:
1. Pull off the road and stop as soon as
it is safe to do so.
2. Place the gear selector lever in "P" (automatic), or neutral (manual transaxle) and set the parking brake.If the air conditioning is on, turn it off.
3. If engine coolant is running out un-
der the car or steam is coming outfrom the hood, stop the engine. Do not open the hood until the enginecoolant has stopped running or the steaming has stopped. If there is no visible loss of coolant and no steam,leave the engine running and check to be sure the engine cooling fan is operating. If the fan is not running,turn the engine off.
4. Check to see if the water pump drive
belt is missing. If it is not missing,check to see that it is tight. If the drive belt seems to be satisfactory, 6. If you cannot find the cause of the
overheating, wait until the engine temperature has returned normal.Then, if the engine coolant has been lost, carefully add engine coolant to the reservoir (page 6-9) to bring thefluid level in the reservoir up to the halfway mark.
7. Proceed with caution, keeping alert for further signs of overheating. Ifoverheating happens again, call a Hyundai dealer for assistance.
CAUTION:
Serious loss of engine coolant indi-cates there is a leak in the cooling system and this should be checked as soon as possible by a Hyundaidealer.

AIR CONDITIONING CARE Keeping the Condenser Clean
The air conditioner condenser (and engine radiator) should be checkedperiodically for accumulation of dirt, dead insects, leaves, etc. These can interfere with maximum cooling effi-ciency. When removing such accu- mulations, brush or hose them away carefully to avoid bending the coolingfans. G140B01A-AAT
Checking the Air Conditioning Operation
1. Start the engine and let it run at
fast idle for several minutes with the air conditioning set at the maxi-mum cold setting.
2. If the air coming out of the in-dash
vents is not cold, have the air con-ditioning system inspected by your Hyundai dealer. G140C01A-AAT Lubrication To lubricate the compressor and the seals in the system, the air condition-ing should be run for at least 10 minutes each week. This is particu- larly important during cool weatherwhen the air conditioning system is not otherwise in use.CAUTION:
Running the air conditioning sys- tem for extended periods of time with a low refrigerant level may damage the compressor.
G130B02A-AAT To Replace the Fluid Recommended brake fluid conform- ing to DOT 3 or DOT 4 specification should be used. The reservoir cap must be fully tightened to avoid con-tamination from foreign matter or moisture. NOTE: Do not allow any other liquids to contaminate the brake fluid. Sealdamage will result.
WARNING:
Use caution when handling brakefluid. It can damage your vision ifyou get it in your eyes. It will also damage your vehicle's paint if spilled on it and not removed im-mediately.

CHANGING THE AIR FILTER (For Evaporator and Blower Unit)
The air filter is located in front of the
evaporator unit behind the glove box. It helps to decrease pollutants from
entering the car and to filter the air.
G145A01L
1. Open the glove box. Lower it down by pushing the both sides of the glove box inward.
3. Lower the glove box down com-pletely. G145A02L
2. Lower the glove box down after
taking out the damper strap fromthe hole.

G140D01S-GAT Checking the Compressor Drive Belt When the air conditioning is being used regularly, the compressor drive belt tension should be checked at least once a month. To check the drive belt tension, press down on the belt halfway between the engine crankshaft and compressorpulleys. Pressing with your finger, you should not be able to deflect this belt anymore than 8.0 mm. If you have
the instruments to check it with a force of 98N (22 lb.), the deflection should be approx. 8.0 mm (0.315inches). If the belt is too loose, have it adjusted by your Hyundai dealer. G140D01L

CHECKING THE BATTERY
WARNING:
Batteries can be dangerous! When working with batteries, care-
fully observe the following pre- cautions to avoid serious injuries.
The fluid in the battery contains a
strong solution of sulfuric acid, whichis poisonous and highly corrosive. Be careful not to spill it on yourself or thecar. If you do spill battery fluid on yourself, immediately do the follow- ing:
o If battery fluid is on your skin, flush the affected areas with water for at least 15 minutes and then seek medical assistance.
o If battery fluid is in your eyes, rinse out your eyes with water and getmedical assistance as soon as possible. While you are being driven to get medical assistance, continueto rinse your eyes by using a sponge or soft cloth saturated with water. o If you swallow battery fluid, drink a
large quantity of water or milk fol-lowed by milk of magnesia, eat araw egg or drink vegetable oil. Get medical assistance as soon as pos- sible.
While batteries are being charged(either by a battery charger or by the vehicle's generator), they produce explosive gases. Always observethese warnings to prevent injuries from occurring:
o Charge batteries only in a well ven- tilated area.
o Do not permit flames, sparks or smoking in the area.
o Keep children away from the area. G210B01A-AAT Checking the Battery Keep the battery clean. Any evidence of corrosion around the battery posts or terminals should be removed using a solution of household baking sodaand warm water. After the battery terminals are dry, cover them with a light coating of grease.

CHECKING ELECTRIC COOL- ING FANS
WARNING:
The cooling fan is controlled by
engine coolant temperature and may sometimes operate even whenthe engine is not running. Use extreme caution when working near the blades of the cooling fan,so that you are not injured by a rotating fan blade. As the coolant temperature decreases the fan willautomatically shut off. This is a normal condition.
G220B01A-AAT
Checking Engine Cooling Fan
The engine cooling fan should come
on automatically if the engine coolanttemperature is high.
G220C01A-AAT
Checking Condenser Cooling Fan
The condenser cooling fan should
come on automatically whenever the air conditioning is in operation.
