2- 10 ice. If the lock is frozen internally, you may be able to thaw it out by using a heated key.Handle the heated key with care to avoid burn-ing your fingers. NOTE: The proper temperature for using the immo- bilizer key is from -40°C to 80°C. If you heatthe immobilizer key over 80°C to open thefrozen lock, it may cause damage to thetransponder in its head.

Use Approved Anti-Freeze in Window Washer System
To keep the water in the window washer sys- tem from freezing, add an approved anti-freezesolution in accordance with instructions on thecontainer. Window washer anti-freeze is avail-able from Hyundai dealers and most auto partsoutlets. Do not use engine coolant or othertypes of anti-freeze as these may damage thefinish. C160I01X-GAT
Don't Let Your Parking Brake Freeze Under some conditions your parking brake can freeze in the engaged position. This is mostlikely to happen when there is an accumulationof snow or ice around or near the rear brakes orif the brakes are wet. If there is a risk theparking brake may freeze, apply it only tempo-

Check Spark Plugs and Ignition System
Inspect your spark plugs as described in Sec- tion 6 and replace them if necessary. Alsocheck all ignition wiring and components to besure they are not cracked, worn or damaged inany way.

Check Battery and Cables
Winter puts additional burdens on the batterysystem. Visually inspect the battery and cablesas described in Section 6. The level of chargein your battery can be checked by your Hyundaidealer or a service station. C160E01A-AAT
Change to "Winter Weight" Oil if Necessary
In some climates it is recommended that a lower viscosity "winter weight" oil be used dur-ing cold weather. See Section 9 for recommen-dations. If you aren't sure what weight oil youshould use, consult your Hyundai dealer. C160G01A-GAT
To Keep Locks from Freezing To keep the locks from freezing, squirt an approved de-icer fluid or glycerine into the keyopening. If a lock is covered with ice, squirt itwith an approved de-icing fluid to remove the
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.
NOTE: Tire chains are not legal in all provinces.
Check province laws before fitting tire chains.

Use High Quality Ethylene Glycol Coolant
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.

To Check the Oil Level G030D01A-GAT Adding Oil

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 CONSUMPTION Function of Engine Oil
Engine oil has the primary function of lubricat-
ing and cooling the inside of the engine. Engine oil consumption
It is normal that an engine should consume
some engine oil while normal driving. The cause of 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.
