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. C160H01A-AAT
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-
C160F01A-AAT
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.
C160D01A-AAT
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.
C160C01A-AAT
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.

WHAT TO DO IN AN EMERGENCY
3-2 2. Turn off all unnecessary lights and acces-
sories in both vehicles.
3. Attach the clamps of the jumper cable in the exact order shown in the illustration. That is, first, attach one clamp of the jumper cable tothe positive (+) post or cable of the dis-charged battery. Then attach the other endof the same cable to the positive (+) post orcable of the booster battery. Next, using theother cable, attach one clamp to the nega-tive (-) post or cable of the booster battery.Then attach the other end of that cable to asolid metal part of the engine away from thebattery. Do not connect the cable to anymoving part.
4. Start the engine in the car with the booster battery and let it run for a few minutes. Thiswill help to assure that the booster battery isfully charged. During the jumping operation,run the engine in this vehicle at about 2,000rpm.
5. Start your engine using the normal starting procedure. After the engine starts, leave thejumper cables connected and let the enginerun at fast idle or about 2,000 rpm for sev-eral minutes.
6. Carefully remove the jumper cables in the reverse order of attachment.
If you do not know why your battery becamedischarged (because the lights were left on,etc.), have the charging system checked byyour Hyundai dealer.
WARNING: The gas produced by the battery during the
jump start operation is highly explosive. If these instructions are not followed exactly,serious personal injury and damage to thevehicle may occur! If you are not sure howto follow this procedure, seek qualified as-sistance. Automobile batteries contain sul-furic acid. This is poisonous and highlycorrosive. When jump starting, wear protec-tive glasses and be careful not to get acid onyourself, your clothing or on the car.
o If you should accidentally get acid on your skin or in your eyes, immediately remove any contaminated clothing and flush thearea with clear water for at least 15 minutes.Then promptly obtain medical attention. Ifyou must be transported to an emergencyfacility, continue to apply water to the affect-ed area with a sponge or cloth.
o The gas produced by the battery during the jump start operation is highly explosive. Donot smoke or allow a spark or an open flamein the vicinity.
o The battery being used to provide the jump start must be 12-volt. If you cannot deter-mine that it is a 12-volt battery, do notattempt to use it for the jump start.
o To jump start a car with a discharged bat- tery, follow this procedure exactly:
1. If the booster battery is installed in another vehicle, be sure the two vehicles are nottouching. D030A01A-AAT
IF THE ENGINE OVERHEATS
If your temperature gauge indicates overheat-ing, you experience a loss of power, or hearloud pinging or knocking, the engine is probablytoo hot. If this happens to you, you should:
1. Pull off the road and stop as soon as it is safe to do so.
2. Place the gear selector lever in "P" (auto- matic transaxle), or neutral (manual
transaxle) and set the parking brake. If theair conditioning is on, turn it off.
3. If engine coolant is running out under the car or steam is coming out from the hood, stopthe engine. Do not open the hood until theengine coolant has stopped running or thesteaming has stopped. If there is no visibleloss of engine coolant and no steam, leavethe engine running and check to be sure theengine cooling fan is operating. If the fan isnot running, turn the engine off.
4. Check to see if the water pump drive belt is missing. If it is not missing, check to see thatit is tight. If the drive belt seems to besatisfactory, check for engine coolant leak-ing from the radiator, hoses or under the car.(If the air conditioning had been in use, it isnormal for cold water to be draining from itwhen you stop).

WHAT TO DO IN AN EMERGENCY 3-3
WARNING: While the engine is running, keep hands,
long hair and clothing away from moving parts such as the fan and drive belts toprevent injury.
5. If the water pump drive belt is broken or engine coolant is leaking out, stop the en- gine immediately and call the nearestHyundai dealer for assistance.
WARNING: Do not remove the radiator cap when the
engine is hot. This may allow coolant to be blown out of the opening and cause seriousburns.
6. If you cannot find the cause of the overheat- ing, wait until the engine temperature has returned to normal. Then, if engine coolanthas been lost, carefully remove the radiator
cap and add engine coolant to bring the fluidlevel in the reservoir up to the halfway mark.
7. Proceed with caution, keeping alert for fur- ther signs of overheating. If overheating hap-pens again, call a Hyundai dealer for assis-tance.
CAUTION: Serious loss of engine coolant indicates
there is a leak in the cooling system and this should be checked as soon as possible by aHyundai dealer. D040A01A-GAT

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.

Recommended Engine Coolant
Use a high quality ethylene-glycol coolant in a
50/50 mix with water. The engine coolant should be compatible with aluminum engine parts. Ad-ditional corrosion inhibitors or additives shouldnot be used. The cooling system must be main-tained with the correct concentration and typeof engine coolant to prevent freezing and corro-sion. Never allow the concentration of antifreeze to exceed the 60% level or go below the 35% levelor damage to the coolant system may result. Forproper concentration when adding or replacingthe coolant, refer to the following table.
35% 40%50%60% G050C01A-AAT
To Check the Coolant Level
The coolant level can be seen on the side of the plastic coolant reservoir. The level of the cool-ant should be between the "LOW" and "FULL"lines on the reservoir when the engine is cold.If the level is below the "LOW" mark, addengine coolant to bring it up between "LOW"and "FULL". If the level is low, inspect forcoolant leaks and recheck the fluid level fre-quently. If the level drops again, visit yourHyundai dealer for an inspection and diagnosisof the reason. G050D02A-AAT
To Change the Engine Coolant
The engine coolant should be changed at thoseintervals specified in the vehicle maintenanceschedule in Section 5. CAUTION: Engine coolant can damage the finish of your car. If you spill engine coolant on thecar, wash it off thoroughly with clean water.
1. Park the car on level ground, set the parking brake and remove the radiator cap whencool.
2. Be sure your drain receptacle is in place. Open the drain cock on the radiator. Allowall the engine coolant to drain from thecooling system, then securely close the draincock.
3. Check Section 9 for the capacity of the cooling system in your car. Then, followingthe manufacturer's directions on the enginecoolant container, add the appropriate quan-tity of engine coolant to the radiator.
