CHECKING ELECTRIC COOLING FANS
G220A01A-AAT
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 coolant 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.
Keep batteries out of the reach of children because batteries contain highly corrosive SULFURIC ACID.Do not allow battery acid to contact your skin, eyes, clothing or paint finish.If any electrolyte gets intoyour eyes, flush your eyeswith clean water for at least 15 minutes and get imme- diate medical attention. Ifpossible, continue to ap- ply water with a sponge or cloth until medical atten-tion is received.If electrolyte gets on yourskin, thoroughly wash thecontacted area.If you feel a pain or a burn-ing sensation, get medi- cal attention immediately. Wear eye protection when charging or working near a battery. Always provide ventilation when working in an en- closed space.o When lifting a plastic-cased bat- tery, excessive pressure on the case may cause battery acid toleak, resulting in personal in- jury. Lift with a battery carrier or with your hands on oppositecorners.
o Never attempt to charge the bat- tery when the battery cables are connected.
o The electrical ignition system works with high voltage. Never touch these componentswith the engine running or the ignition switched on.

Checking Engine Cooling Fan
The engine coolant fan should come on automatically if the engine coolant temperature is high. G220C01A-AAT
Checking Condenser Cooling Fan
The condenser coolant fan should come on automatically whenever the air conditioning is in operation. G230A01GK-GAT
POWER STEERING FLUID LEVEL
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:
o Grinding noise from the power
steering pump may be heard im- mediately after the engine is started in extremely cold condi- tions (below - 20°C). If the noisestops during warm up, there is no abnormal function in the sys- tem. It is due to a power steeringfluid characteristic in extremely cold conditions.
o Do not start the engine when the power steering oil reservoir isempty.

4. Clean the head light lenses and
turn on the headlights.
5. Open the hood.
6. Draw the vertical line (through the center of each headlight beam pat- tern) and the horizontal line (through the center of each headlight beampattern) on the aiming screen.And then, draw a parallel line at 30mm (1.18 in.) under the horizontal line.
7. Adjust each cut-off line of the low beam to the parallel line with aphillips screwdriver - VERTICAL AIMING.
8. Adjust each cut-off line of the low
beam to each vertical line with aphillips screwdriver - HORIZON- TAL AIMING.
Before performing aiming adjustment,
make sure of the following.

3RUNNING IN YOUR NEW HYUNDAI
B020A01S-EAT The longevity and performance of the vehicle are greatly affected by the care exercised during the first 1,000 miles of motoring. Because of modern manu-facturing techniques, rigid guidelines regarding maximum road speeds have become unnecessary. However, cer-tain precautions should be observed in order to obtain the best possible per- formance and useful life from the ve-hicle.
1) Do not race the engine without a
load (i.e revving the engine in neu- tral).
2) During the first 500 miles the maxi- mum engine speed should be re-stricted to 3,000 rpm and gradually increased thereafter.
3) Avoid prolonged constant speed operation. The internal componentsof the engine will become morequickly run in if the operation speed is varied during the running in pe- riod.
4) Never allow the engine to labour. Use the gearbox freely and avoidlarge throttle openings when theengine speed is below 1,500 rpm.BEFORE ENTERING THE VEHICLEAFTER ENTERING THE VEHICLE
YB020A1-E
o Ensure that all windows, mirrors
and lamps are clean.
o Check condition of all tyres.
o Ensure that no fluid leaks are evi-
dent.
o Ensure that the area around the vehicle is clear before driving off. YB020B1-E
o Ensure that all occupants fasten
and correctly adjust seat belts.
o Ensure that seat and head restraint positions are adjusted for optimum safety, control and comfort.
o Adjust interior and exterior rear view mirrors.
o Verify correct operation of lamps, horn and other electrical equipment.
o Ensure that warning lamps illumi-
nate when ignition is turned on.
NOTE: Fluid levels such as engine oil, en- gine coolant, brake and windscreenwasher fluid should be checked daily or at each refuelling, which- ever occurs sooner.
