G120B01A-AAT Checking the Brake Fluid Level
! CAUTION:
Because brakes are essential to the safe operation of the car, it is sug- gested that they be checked andinspected by your Hyundai dealer. The brakes should be checked and inspected for wear at those inter-vals specified in the vehicle mainte- nance schedule in Section 5.
WARNING:
Use caution when handling brake fluid. It can damage your vision if it gets into your eyes. It will also dam- age your vehicle's paint if spilledon it and not removed immediately.
G120C02A-AAT Recommended Brake Fluid Use only hydraulic brake fluid con- forming to DOT 3 or DOT 4 specifica-tions in your braking system. Follow the instructions printed on the con- tainer. G120D01A-AAT To Check the Fluid Level

26POWER STEERING FLUID LEVEL
G230A03A-GAT The power steering fluid level should be checked regularly. To check the power steering fluid level, be sure the ignition is "OFF", thencheck to make certain that the power steering fluid level is between the "MAX" and "MIN" level markings on the fluidreservoir. NOTE: Grinding noise from the power steer- ing pump may be heard immediatelyafter the engine is started in extremely cold conditions (below - 20°C). If the noise stops during warm up, there isno abnormal function in the system. HHR5014CHECKING ELECTRIC COOLING FANS
!
G220B01A-AAT Checking Engine Cooling Fan The engine cooling fan should come on automatically if the engine coolant tem- perature is high. G220C01TB-GAT Checking Condenser Cooling Fan When the air conditioning is in opera- tion, the condenser cooling fan comeson automatically to be controlled by ECU.
G220A01A-AAT
WARNING:
The cooling fan is controlled by en- gine coolant temperature and may sometimes operate even when the engine is not running. Use extremecaution when working near the blades of the cooling fan, so that you are not injured by a rotating fanblade. As the engine coolant temper- ature decreases the fan will automat- ically shut off. This is a normal con-dition.
o When lifting a plastic-cased bat- tery, excessive pressure on the case may cause battery acid toleak, resulting in personal injury. Lift with a battery carrier or with your hands on opposite corners.
o Never attempt to charge the bat- tery when the battery cables areconnected.
o The electrical ignition system works with high voltage.Never touch these componentswith the engine running or the ignition switched on.
