Checking the Battery Keep the battery clean. Any evidence of corro-
sion around the battery posts or terminals shouldbe removed using a solution of household bak-ing soda and warm water. After the batteryterminals are dry, cover them with a light coat-ing of grease.
G220A01A-AAT
CHECKING ELECTRIC COOLING FANS WARNING: The cooling fan is controlled by engine cool-
ant temperature and may sometimes oper- ate even when the engine is not running.Use extreme caution when working near theblades of the coolant fan, so that you are notinjured by a rotating fan blade. As the cool-ant temperature decreases the fan will auto-matically shut off. This is a normal condi-tion.
G220B01A-AAT
Checking Engine Cooling Fan The engine coolant fan should come on auto-
matically if the engine coolant temperature ishigh.
o Charge batteries only in a well ventilated
area.
o Do not permit flames, sparks or smoking in the area.

OIL PRESSURE WARNING LAMP
CAUTION: If the oil pressure lamp illuminates when the engine is running, an insufficient oil pressurelevel for continued safe operation of the en-gine exists. Continued operation of the en-gine in this condition may result in seriousengine damage. Under normal circumstances, the lamp will illu- minate when the ignition is turned "on" and will beextinguished when the engine is started.If the oil pressure warning lamp illuminates whilstthe engine is running, stop the engine immedi-ately and check the engine oil level. If the level isinsufficient, add the required amount of oil asindicated by the engine oil dipstick. If the lampfails to extinguish when the engine is restarted,do not continue to operate the vehicle.If the oil pressure lamp illuminates during normaloperation and the cause is not an insufficient oillevel, or the lamp fails to illuminate when theignition is turned "on", contact the nearest Hyundaidealer before further operating the vehicle.

LOW FUEL LEVEL WARNING LAMP
The low fuel warning lamp serves to warn the driver that the remaining fuel quantity is approxi-mately 9 litres and that the vehicle should berefuelled. If the vehicle is driven for an extendedperiod with the low fuel warning lamp illuminatedthere exists a possibility that misfiring due to fuel
becoming defective, approximately fifty per centof the normal braking performance will be avail-able.If failure of one of the circuits occurs, the requiredamount of pedal effort, pedal travel and stoppingdistance will be increased. Use of the gearbox isrecommended to assist in bringing the vehicle torest. The vehicle must not be driven once brakefailure has occurred until the system has beenrepaired and is functioning normally.The braking system employs a vacuum servo inorder that the pedal efforts are reduced. Powerfor the servo is derived from the engine andtherefore, in the event of the engine stopping orthe vehicle being towed, pedal efforts will besubstantially increased. SB210M1-E
