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 cer-tain that the power steering fluid level is be-tween the "MAX" and "MIN" level markings onthe fluid reservoir.
NOTE: Grinding noise from the power steering
pump may be heard immediately after the engine is started in extremely cold condi-tions (below - 20°F). If the noise stops dur-

WARNING AND INDICATOR LIGHTS
SB210K1-ELOW OIL PRESSURE WARN ING LAMP
SB210G1-ETURN SIGNAL INDICA- TOR LAMPS
Operation of a turn signal is indicated by the warning lamp located in theinstrument cluster. If the lamp fails to illuminate or does not flash, a malfunc- tion within the turn signal system isindicated. 260P02Y-EAT ABS Service Reminder Indicator (Not all models)
When the key is turned to the "ON" position, the Anti-Lock Brake System SRI will come on and then go off in afew seconds. If the ABS SRI remains on, comes on while driving, or does not come on when the key is turned to the"ON" position, this indicates that there may be a problem with the ABS. If this occurs, have your vehiclechecked by your Hyundai dealer as soon as possible. The normal braking system will still be operational, butwithout the assistance of the anti-lock brake system. WARNING:
If the both ABS SRI and ParkingBrake/Brake fluid level warning lights remain "ON" or come on whiledriving, there may be a problem with E.B.D (Electronic brake force distribution).If this occurs, avoid sudden stops and have your vehicle checked by your Hyundai dealer as soon aspossible.SB210J1-E HIGH BEAM INDICATOR LAMP
The high beam indicator lamp will illu- minate whenever the headlamps areswitched to high beam of flash posi- tion.
CAUTION:
If the oil pressure warning light illuminates when the engine is run- ning, an insufficient oil pressure level for continued safe operationof the engine exists. Continued operation of the engine in this con- dition may result in serious enginedamage. Under normal circumstances, the light will illuminate when the igni- tion is turned "on" and will be extin- guished when the engine is started.

If the oil pressure warning light illuminates whilst the engine is run- ning, stop the engine immediately and check the engine oil level. If thelevel is insufficient, add the required amount of oil as indicated by the engine oil dipstick. If the light failsto extinguish when the engine is restarted, do not continue to oper- ate the vehicle.If the oil pressure light illuminates during normal operation and the cause is not an insufficient oil level,or the light fails to illuminate when the ignition is turned "on", contact the nearest Hyundai dealer beforefurther operating the vehicle.

PARKING BRAKE/ BRAKE FLUID LEVELWARNING LAMP
WARNING:
In the event of problems being sus- pected with the braking system, the advice of the nearest Hyundai dealer must be sought before the vehicleis driven. Driving the vehicle with either an electrical or hydraulic brak- ing system defect may be danger-ous, resulting in accident or per- sonal injury. Warning lamp operation The parking brake/brake fluid level warning lamp will be illuminated when- ever the ignition switch is turned to the "ON" or "START" position when theparking brake is applied and must be extinguished in a three seconds after the engine starts.If the warning lamp fails to extinguish or illuminates at any other time, the vehicle must be brought to rest in asafe location and the level of brake fluid in the reservoir checked. If the fluid level is incorrect, fluid conforming to DOT 3 or DOT 4 specifications shouldbe added. If, after correcting the brake fluid level, the warning lamp continues to be illuminated, the advice of thenearest Hyundai dealer must be sought
before the vehicle is driven again. The Hyundai Coupe is equipped with adiagonally split dual braking system which will ensure that in the event of one of the brake circuits becomingdefective, approximately fifty per cent of the normal braking performance will be available.If failure of one of the circuits occurs, the required amount of pedal effort, pedal travel and stopping distance willbe increased. Use of the gearbox is recommended to assist in bringing the vehicle to rest. The vehicle must not bedriven once brake failure has occurred until the system has been repaired and is functioning normally.The braking system employs a vacuum servo in order that the pedal efforts are reduced. Power for the servo is de-rived from the engine and therefore, in the event of the engine stopping or the vehicle being towed, pedal efforts willbe substantially increased.

CHARGING SYSTEM WARNING LAMP
The charging system warning lamp should illuminate when the ignitionswitch is turned to the "ON" position and should be extinguished when the engine is started.

If the lamp illumi- nates whilst the vehicle is being driven, stop the vehicle as soon as it is safe todo so and check the condition of the generator drive belt. If the belt is in place and the tension is satisfactory,the advice of a Hyundai dealer should be sought.

If the drive belt (generator belt) is loose, broken, or missing while thevehicle is driving, there may be a serious malfunction, engine could overheat because this belt alsodrives the water pump.
SB210P1-E LOW FUEL LEVEL WARNING LAMP
The low fuel warning lamp serves to warn the driver that the remaining fuelquantity is approximately 9 litres and that the vehicle should be refuelled. If the vehicle is driven for an extendedperiod with the low fuel warning lamp illuminated there exists a possibility that misfiring due to fuel shortage mayoccur. This situation must be avoided to prevent damage to the catalyst oc- curring.

!WARNING:
Fuel vapours are dangerous. Be- fore refuelling, turn off the engine and never allow sparks, lit ciga-rettes or open flames near the filler area. When releasing the filler cap, a small amount of residual pres-sure may generate a slight hissing sound which is not indicative of an abnormality. In the event of the fuelfiller cap requiring replacement, only a Genuine Hyundai replace- ment part should be used to pre-vent fuel leakage. HGK2018Q
SB440A1-E (Not all models) The fuel filler lid may be opened from inside the vehicle by pulling up on thefuel filler lid release. NOTE: If the fuel filler lid will not open because ice has formed around it, tap lightly or push on the lid to break the ice and release the lid. Donot lever the lid. If necessary, spray around the lid with an approved de- icer fluid (do not use radiator anti-freeze) or move the vehicle to a warm place and allow the ice to melt.REMOTE FUEL FILLER LID RELEASE
