B260P02Y-AAT ABS Service Reminder Indica- tor (SRI) (If installed)
When the key is turned to the "ON" position, the ABS SRI will come on and then go off in a fewseconds. If the ABS SRI remains on, comes onwhile driving, or does not come on when the keyis turned to the "ON" position, this indicates thatthere may be a problem with the ABS. If this occurs, have your vehicle checked by your Hyundai dealer as soon as possible. The normalbraking system will still be operational, but with-out the assistance of the anti-lock brake system.

Turn Signal Indicator Lights
The blinking green arrows on the instrumentpanel show the direction indicated by the turnsignals. If the arrow comes on but does notilluminate, blinks more rapidly than normal, ordoes not illuminate at all, a malfunction in the turnsignal system is indicated. Your dealer should beconsulted for repairs. B260G01A-AAT
Oil Pressure Warning Light
CAUTION: If the oil pressure warning light stays on while the engine is running, serious enginedamage may result. The oil pressure warninglight comes on whenever there is insufficientoil pressure. In normal operation, it shouldcome on when the ignition switch is turnedon, then go out when the engine is started. Ifthe oil pressure warning light stays on whilethe engine is running, there is a seriousmalfunction.If this happens, stop the car as soon as it issafe to do so, turn off the engine and checkthe oil level. If the oil level is low, fill the engineoil to the proper level and start the engineagain. If the light stays on with the enginerunning, turn the engine off immediately. Inany instance where the oil light stays onwhen the engine is running, the engine shouldbe checked by an Hyundai dealer before thecar is driven again.

Failure to do so may adversely affect the safety
and handling of your car. Speeding, rapid accel-eration, sudden brake applications, and sharpturns are potentially very hazardous practices.During deceleration, use engine braking to thefullest extent. Sudden brake applications onsnowy or icy roads may cause skids to occur.
You need to keep sufficient distance betweenthe vehicle in front and your vehicle. Also, applythe brake gently.
It should be noted that installing tire chains on
the tire will provide a greater driving force, butwill not prevent side skids.

Your Hyundai is delivered with high quality
ethylene glycol coolant in the cooling system. It is the only type of coolant that should be usedbecause it helps prevent corrosion in the cool-ing system, lubricates the water pump andprevents freezing. Be sure to replace or replen-ish your coolant in accordance with the main-tenance schedule in Section 5. Before winter,have your coolant tested to assure that itsfreezing point is sufficient for the temperaturesanticipated during the winter.

Before checking the oil, warm up the engine to
the normal operating temperature and be sure your car is parked on level ground. Turn theengine off.
Wait a minute, then remove the dipstick, wipe it
off, fully reinsert the dipstick and withdraw itagain. Then note the highest level the oil hasreached on the dipstick. It should be betweenthe upper ("FULL") and lower ("LOW") range. If the oil level is close to or below the "L" mark,add oil until it reaches the "F" mark. To add oil:
1. Remove the oil filler cap by turning it counter-
clockwise.
2. Add oil, then check the level again. Do not overfill.
3. Replace the cap by turning it clockwise. The distance between the "F" and "L" marks is equal to about 1 liter of oil. G350A01A-GAT

Engine oil has the primary function of lubricat-

Engine oil consumption
Engine oil consumption
It is normal that an engine should consume
some engine oil while normal driving. The causeof oil consumption in a normal engine are asfollows;
o Engine oil is used to lubricate pistons, piston rings and cylinders. A thin film of oil is left on the cylinder wall when a piston moves downwards in thecylinder. High negative pressure generated
during engine operation sucks some of theoil into the combustion chamber. This oil with some oil of the cylinder wall is
burned by the high temperature combustiongases during the combustion process.
o The engine oil consumption is strongly ef- fected by the viscosity and quality of oil,engine rpm and driving condition etc. Theengine oil is more consumed under severedriving conditions such as high speeds and
frequent acceleration and deceleration thannormal driving condition.
