Handling Spare Tyre
6. If the cause of the overheating cannot be
found, wait until the engine temperature has returned to normal. Then, if coolant hasbeen lost, carefully remove the radiator capand add water to bring the fluid level in thereservoir up to the base of the radiator fill
opening. Fill the coolant expansion tank tothe halfway mark.
7. Proceed with caution until it is established that the engine is operating normally. If theengine overheats repeatedly, the advice of aHyundai dealer should be sought.
CAUTION: Serious loss of coolant indicates there is aleak in the cooling system and this shouldbe checked as soon as possible by a Hyundaidealer. 3. Passengers must not be allowed to remain
inside the vehicle during wheel changing. Ifa puncture occurs whilst the vehicle is on amotorway, the passengers should take ref-uge on the motorway embankment to avoidthe possibility of injury occurring should thevehicle be struck by other motorway traffic.
4. Wheel changing should be performed ac- cording to the following instructions.

To Check the Oil Level
Before checking the oil, warm up the engine to
normal operating temperature and be sure it is parked on level ground. Turn the engine 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 ("F") and lower ("L") range. ZG030D1-A
Adding Oil
G030D01A
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 coun- terclockwise.
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 quart 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
If 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.
o A thin film of oil is left on the cylinder wall when a piston moves downwards in the cylinder. High negative pressure generatedduring 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. The
engine oil is more consumed under severedriving conditions such as high speeds and
frequent acceleration and deceleration thannormal driving condition.

Recommended Coolant
G050B01A
Use a high quality ethylene-glycol coolant in a
50/50 mix with water. The coolant should be compatible with aluminum engine parts. Addi-tional corrosion inhibitors or additives shouldnot be used. The cooling system must be main-tained with the correct concentration and typeof coolant to prevent freezing and corrosion.
NEVER allow the concentration of antifreeze to
exceed the 60% level or go below the 35% levelor damage to the coolant system may result.For proper concentration when adding or re-placing the coolant, refer to the following table.
Coolant concentration
ZG050C1-A
To Check the Coolant Level
G050C01A
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. If the level is below the"LOW" mark, add coolant to bring it up between"LOW" and "FULL". If the level is low, inspectfor coolant leaks and recheck the fluid levelfrequently. If the level drops again, visit yourHyundai dealer for an inspection and diagnosisof the reason. ZG050D2-A
To Change the Coolant
The coolant should be changed at those inter-vals specified in the vehicle maintenance sched-ule in Section 5. NOTE: Coolant can damage the finish of your car. If you spill coolant on the car, wash it offthoroughly with clear 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 coolant to drain from the coolingsystem, then securely close the drain cock.
3. Check Section 9 for the capacity of the cooling system in your car. Then, followingthe manufacturer’s directions on the coolantcontainer, add the appropriate quantity ofcoolant to the radiator.

4. Turn the radiator cap counterclockwise with- out pressing down on it, until it stops. This relieves any pressure remaining in the cool-ing system. And remove the radiator cap bypushing down and turning counterclockwise. Now fill the radiator with clean demineral- ized or distilled water. Continue to add cleandemineralized or distilled water in small quan-tities until the fluid level stays up in theradiator neck. 5. Start the engine, top off the radiator with
water and then add engine coolant to thereservoir until the level is between "LOW"and "FULL".
6. Replace the radiator and reservoir caps and check to be sure the drain cocks are fullyclosed and not leaking.
WARNING: The cooling fan is controlled by engine cool-
ant temperature and may sometimes oper- ate even when the engine is not running.Use extreme caution when working near theblades of the cooling fan so that you are notinjured by a rotating fan blade. As the en-gine coolant temperature decreases, the fanwill automatically shut off. This is a normalcondition. AG060B1-E
SPARK PLUG REPLACEMENT
This operation should only be performed when
the engine is cold.
1. Remove plug lead from the spark plug to be replaced, pulling the lead by the rubber cap. (Pulling the lead may damage the carbonconductor).
2. Clean around the base of the plug to be removed, and install the plug socket ensur-ing that the ceramic insulator does not be-come damaged. Turn the socket anti-clock-wise to remove the plug.
G060C01A
NOTE: Spark plugs must only be cleaned using
purpose designed equipment. Wire brush-ing may damage the centre electrode insula-tor causing mis-firing to occur.

While the engine is idling, apply the brakes and move the gear selector lever from "P" to each
of its other positions — "R", "N", "D", "2", "L" —and then return to "N". With the engine stillidling:
1. Open the hood, being careful to keep hands, long hair and clothing clear of any movingparts.
2. Remove the transaxle dipstick, wipe it clean, reinsert the dipstick as far as it will go, thenremove it again. Now check the fluid level on
the dipstick. It should be in the "HOT" rangeon the dipstick.
Fluid level must be within this range
3. If the transaxle fluid level is low, use a funnel to add transaxle fluid through the dipsticktube until the level reaches the "HOT" range.
Do not overfill.

G120A01A-AAT CHECKING THE BRAKES CAUTION: Because brakes are essential to the safe oper- ation of the car, it is suggested that they bechecked and inspected by your Hyundai dealer.The brakes should be checked and inspectedfor wear at those intervals specified in thevehicle maintenance schedule in Section 5. G120B01A-AAT
Checking the Brake Fluid Level WARNING:
Use caution when handling brake fluid. It
can damage your vision if it gets into your eyes. It will also damage your vehicle’s paint
if spilled on it and not removed immediately.
G120C02A-AAT
Recommended Brake Fluid Use only hydraulic brake fluid conforming to
DOT 3 or DOT 4 specifications in your brakingsystem. Follow the instructions printed on thecontainer.
G120D01A-AAT
To Check the Fluid Level The fluid level in the brake fluid reservoir should
be checked periodically. The level should bebetween the "MIN" and "MAX" marks on theside of the reservoir. If the level is at or below
the "MIN" mark, carefully add fluid to bring it upto "MAX". Do not overfill.
WARNING: The cooling fan is controlled by engine cool-
ant temperature and may sometimes oper- ate even when the engine is not running.
Use extreme caution when working near theblades of the cooling fan, so that you are notinjured by a rotating fan blade. As the en-
gine coolant temperature decreases, the fanwill automatically shut off. This is a normalcondition. NOTE:
Only lint free cloth should be used for wip-
ing the dipstick. The presence of lint within the transaxle may cause problems with thenormal function of the transaxle.
