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.

Stopper
1. Open the glove box. Remove the stoppers on the both sides of the glove box. 2. Lower the glove box down com-
pletely after taking out the damperstrap from the hole.

3. Remove the glove box mounting bolts (1) and screws (2) from theglove box assembly, and then de-tach the glove box assembly.

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 BRAKE PEDAL FREEPLAY
HXGS508
3 ~ 8 mm (0.12 ~ 0.31 in.)
With the engine off, press down on
the brake pedal several times to re- duce the vacuum in the brake booster.
Then, using your hand, press down
slowly on the brake pedal until youfeel a change in resistance. This isthe brake pedal freeplay.
The freeplay should be within the
limits specified in the illustration. If it is not, have it inspected by your Hyundai dealer and adjusted or re-paired if necessary.G160A01A-GAT
CHECKING CLUTCH PEDAL FREEPLAY
G160A01E
6 ~ 13 mm (0.24 ~ 0.51 in.)
With the engine off, press lightly on
the clutch pedal until you feel a change in resistance. This is the clutch pedalfreeplay. The freeplay should be within the limits specified in the illustration. If it is not, have it inspected by yourHyundai dealer and adjusted or re- paired if necessary.G150A01A-GAT CHECKING STEERING WHEEL FREEPLAY
G150A01L
To check the steering wheel freeplay, stop the car with the wheels pointed straight ahead and gently move thesteering wheel back and forth. Use very light finger pressure and be sen- sitive to changes in resistance thatmark the limits of the freeplay. If the freeplay is greater than specified, have it inspected by your Hyundai dealerand adjusted or repaired if neces- sary. 30 mm(1.18 in.)

CHECKING DRIVE BELTS
Drive belts should be checked peri-
odically for proper tension and ad- justed if necessary. At the same time, belts should be examined for cracks,wear, fraying or other evidence of deterioration and replaced if neces- sary.
Belt routing should also be checked
to be sure there is no interferencebetween the belts and other parts ofthe engine. After a belt is replaced, the new belt should be adjusted again after two or three weeks to eliminateslack resulting from initial stretching after use.
G180A01A-GAT
CHECKING BRAKE PEDAL CLEARANCE
G180A01L
75 mm (2.95 in.)
You need a helper to check the brake pedal clearance. With the engine run- ning, have your helper press down onthe brake pedal several times and then hold it down with a force of about 490 N (50 Kg, 110 lbs). The brakepedal clearance is the distance from the top surface of the brake pedal to the asphalt sheeting under the floormat.If the brake pedal clearance is notwithin the limits specified in the illus-tration, have it inspected by your Hyundai dealer and adjusted or re- paired if necessary.

CHECKING AND REPLACING FUSES Replacing a Fusible Link
A fusible link will melt if the electrical circuits from the battery are ever over- loaded, thus preventing damage tothe entire wiring harness. (This could be caused by a short in the system drawing too much current.) If thisever happens, have a Hyundai dealer determine the cause, repair the sys- tem and replace the fusible link. Thefusible links are located in a under hood junction box for easy inspec- tion. G200A01L

POWER STEERING HOSES
It is suggested that you check the
power steering hose connections for fluid leakage at regular intervals.
The power steering hoses should be
replaced if there is severe surface cracking, scuffing or worn spots. De- terioration of the hose could causepremature failure.
G230A03A-GAT
POWER STEERING FLUID LEVEL
HXG2006
The power steering fluid level should
be checked regularly.
To check the power steering fluid
level, be sure the ignition is "OFF", then check to make certain that the power steering fluid level is betweenthe "MAX" and "MIN" level markings on the fluid reservoir.
NOTE: Grinding noise from the power
steering pump may be heard im- mediately after the engine is started in extremely cold conditions (be- low - 20°C). In this case, if the noise stops during warm up, there is no abnormal function in the sys- tem. This is due to a power steer-ing fluid characteristic in extremely cold conditions. Recommended Fluid Use PSF-3 type fluid. NOTE: Do not start the engine when the power steering oil reservoir is empty.
G220A01A-AAT
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.

HEADLIGHT AIMING ADJUST- MENT
HID Type (If installed)
WARNING:
If you need headlight aiming ad- justment, have your vehicle in- spected by your Hyundai Dealer. Don't attempt to replace or inspect the HID headlight bulb to prevent danger of an electric shock.
Vertical Aiming HorizontalAiming
Before performing aiming adjustment, make sure of the following.
1. Keep all tires inflated to the correct pressure.
2. Place the vehicle on level ground
and press the front bumper & rear bumper down several times. Place the vehicle at a distance of 3 m (118 in.) from the test wall.
3. See that the vehicle is unloaded (except for full levels of coolant,engine oil and fuel, and spare tire,jack, and tools). Have the driver or equivalent weight placed in driver's seat.
4. Clean the head light lenses and
turn on the headlights (low beam).
5. Open the hood.
6. Draw the vertical line (through the center of each headlight) and the horizontal line (through the center of each headlight) on the aimingscreen. And then, draw the parallel line at 30 mm (1.18 in.) place under the horizontal line.
