ENGINE COOLANT CHECK- ING AND REPLACING
SG050B1-E Coolant recommended G050B01FC
SG050A1-E
WARNING:
Do not remove the radiator cap when the engine is hot, since the system is pressurised and coolant may be ejected from the radiator resultingin scalding.
G050B02FC
Petrol engine Diesel engine
Only ethylene glycol based coolantwith a corrosion inhibitor suited to alu- minium alloy engine components should be used in the cooling system. No further additives or inhibitors should be used. The coolant specific gravityshould be checked as prescribed in the maintenance schedule to ensure adequate frost and corrosion protec-tion. In addition, the engine coolant must be replaced at the specified in- terval since the corrosion inhibitor prop-erties deteriorate with time. It is important to note that whilst an
increase in the concentration of antifreeze gives an increase in the level of frost protection, a solution which is in excess of 65% anti freeze will result inreduced frost protection and engine overheating. Therefore the recom- mended concentration of 50% shouldnot be exceeded for general use. The use of methanol based anti freeze
compounds may result in engine over-heating and will invalidate the vehicle warranty.
NOTE: It is imperative that vehicles fitted
with an air conditioning system have a coolant concentration of the rec-ommended strength at all times. The use of the air conditioning sys- tem when the cooling system isfilled with water only will result in the heater matrix freezing and sub- sequently bursting.

To Check the Coolant Level If the level is below the "L" mark, add coolant of the correct concentrationuntil the level is between the "L" and "F" marks. If the level falls below the "L" mark on a regular basis despitebeing topped up, consult a Hyundai authorised repairer.

SG050D2-E
To Change the Coolant
The coolant should be changed at
those intervals specified in the vehicle maintenance schedule in Section 5.
NOTE: Care should be taken to ensure that
coolant is not allowed to spill onto the paintwork since the finish maybecome damaged. If coolant spill- age occurs, the affected area should be rinsed thoroughly with water.
1. Park the vehicle on level ground
and ensure that the parking brake is firmly applied, and the engine al- lowed to cool. Do not attempt this operation whilst the engine is hot since burning or scalding may result. 2. Prepare a suitable receptacle to
collect the displaced coolant and position this under the radiator drain tap.
3. With the heater temperature control set to the "HOT" position, removethe radiator cap and open the radia- tor drain tap.
4. When the engine coolant has drained completely, close the drain tap en-suring that this is not over tight- ened.
5. Prepare a suitable quantity of new engine coolant (refer to section 9)and pour this into the radiator.

G070A02FC
Diesel engine Lift out the air flow sensor followed by
the air cleaner element. Replacement of the element is the reverse of the above.
CAUTION:
o The air flow sensor is a precision engineered electronic measuringdevice and therefore care should be exercised that the air flow sen-sor is not damaged during re- placement of the element.
o When removing the air cleaner element, be careful that dust or dirt does not enter the air intake.These may result in damage to the air cleaner element.
To ensure maximum filtration perfor-
mance and continued engine perfor- mance, only genuine Hyundai replace-ments should be used.
WINDSCREEN WIPER BLADES
G080A01A-EAT The wiper blades should be carefully inspected from time to time and cleaned to remove accumulations ofroad film or other debris.To clean the wiper blades and arms,use a clean sponge or cloth with a mild soap or detergent and water. If the wipers continue to streak or smear theglass, replace them with genuine Hyundai replacement. HEF119
To replace the air cleaner element, remove the air intake ducting from theair flow sensor body and unfasten the spring clips holding the air flow sensor top to the body.

BRAKE SYSTEM CHECKING
Fluid level should be within this range
C090A03FC
WARNING:
The cooling fan is controlled by engine coolant temperature and may sometimes operate even when the engine is not running. Use extremecaution when working near the blades of the cooling fan so that you are not injured by a rotating fanblade. As the engine coolant tem- perature decreases, the fan will au- tomatically shut off. This is a nor-mal condition. WARNING (Diesel only):
Never work on injection system with
engine running or within 30 sec- onds after shutting off engine. Highpressure pump, rail, injectors and high pressure pipes are subject to high pressure even after the enginestopped. The fuel jet produced by fuel leaks may cause serious injury, if it contacts the body.
People using pacemakers should
ensure that they keep a distance of30cm from the ECU or wiring har- ness within the engine room whilst engine is running, since the highcurrents in the Common Rail sys- tem produce considerable magnetic fields. SG120A1-E
CAUTION:
Correct operation of the braking
system is essential to the safe op-eration of the vehicle and therefore, any maintenance operations other than those listed below should beentrusted to a Hyundai authorised repairer.

G120D02FC
Diesel engine WARNING:
Brake fluid is hygroscopic and should never be stored in an un- sealed container. The presence ofwater in the braking system will cause vapour locks and increase the possibility of brake fade alongwith promoting corrosion within the braking system. The brake fluid must be changed at the specifiedtime or mileage interval to ensure continued safe operation of the sys- tem. Brake fluid will cause rapidand serious damage to paintwork. If accidental spillage occurs, the af- fected area must be rinsed withwater immediately. Do not allow brake fluid to come into contact with the eyes or to be ingested andensure that fluid is safely stored away form the reach of children.
The fluid level in the brake fluid reser-voir should be checked periodically. The level should be between the "MIN" and "MAX" marks on the side of thereservoir. If the level is at or below the "MIN" mark, fluid should be added having carefully cleaned the area sur-rounding the reservoir cap to ensure that dirt is not allowed to enter the system. It should be noted that thebrake fluid level will decrease slightly as the friction linings of the pads and shoes become worn and that this is anormal condition.

Adding Fluid
Recommended brake fluid conforming
to DOT 3 or DOT 4 should be used.The reservoir cap must be fully tight- ened to avoid contamination from for-eign matter or moisture.
CAUTION:
Brake fluid is hygroscopic and
should never be stored in an un-sealed container. Do not allow pe-troleum base fluid to contaminate the brake fluid since damage to the rubber seals of the system may re-sult.
! WARNING:
Brake fluid will cause rapid and
serious damage to paintwork. If ac- cidental spillage occurs, the affectedarea must be rinsed with water im- mediately. Do not allow brake fluid to come into contact with the eyesor to be ingested and ensure that fluid is safely stored away form the reach of children.

POWER STEERING HOSES
Power steering hoses should be
checked for damage, deterioration and leakage at each service. To check the power steering fluid level,
be sure the ignition is "OFF", thencheck to make certain that the power steering fluid level is between the "MAX" and "MIN" level markings onthe fluid reservoir.
NOTE: Grinding noise from power steering
pump may be heard immediately after the engine is started in ex-tremely cold condition (below -4°F). If the noise stops dur- ing warm up, there is no abnormalfunction in the system. This is due to a power steering fluid character- istic in extremely cold conditions. FLUID RECOMMENDATION
Only automatic transmission fluid
meeting the specification of PSF-3 or Dexron 2 should be used in the power steering system.

2. Pump the hand pump until there are
no more bubbles in the fuel coming out of the air pipe. When doing this, place a cloth around the air pipe to prevent the escaping fuel from spew-ing about.
3. Replace the air cap when there are no more bubbles in the fuel.
4. Continue pumping until the hand pump becomes stiff.
5. Finally, check to be sure that there
is no leakage of fuel. If in doubt, consult your nearest Hyundai authorised repairer. G350B01FC
