2003 Hyundai Matrix heater

DRIVING YOUR HYUNDAI
2- 12 NOTE: Never allow undiluted screen washer fluid additive to spill upon the paintwork or useengine coolant anti-freeze since damage tothe paintwork may result.
o When driving in extreme conditions, the windscreen wiper blades may fail to clearthe screen properly due to the formation ofice upon the blade edge. It will therefore benecessary to periodically remove such iceto restore their efficiency.
o If the power operated door mirrors become frozen, attempts to adjust these may dam-age the mechanism.
o The formation of snow or ice built up inside the wheel arches may interfere with theroad wheels or steering mechanism. Insuch instances, unusual noises or an in-crease in steering effort may result. There-fore, ensure that the wheel arches arechecked periodically and any accumulatedsnow or ice removed.
o It is advisable to carry emergency equip- ment including, torch, shovel, tow rope,blankets etc., if a journey is to be under-taken into areas of severe road conditions.

Door Locks
Should the door lock mechanism becomefrozen, a proprietary lock de-icer should beused. Alternatively, warming the door keymay thaw the door lock. However, the keyshould be handled carefully to avoid burningthe fingers. Never attempt to thaw a frozen door lock using hot water, since the water will eventu-ally freeze and compound the problem. NOTE: The proper temperature for using the im-mobilizer key is from -40°F to 176°F (-40°Cto 80°C). If you heat the immobilizer keyover 176°F (80°C) to open the frozen lock,it may cause damage to the transponderin its head.
SC170E1-E Windscreen Washers and Wipers The windscreen washer bottle should be filled
with a solution of water and a proprietary winter screen wash additive. The windscreenwipers should not be used if the blades arefrozen to the windscreen or if they are cov-ered with snow, before this is removed.

Electrical System
Winter conditions impose severe demandsupon vehicle electrical systems, particularlythe charging circuit. The battery condition andperformance along with the alternator perfor-mance and drive belt condition should bechecked prior to the onset of winter. ZC170C1-E Anti-freeze/Corrosion inhibitorThe cooling system must always contain an Ethylene-Glycol based anti-freeze solution.The system is filled during manufacture withsolution of the correct strength which shouldbe checked before the onset of winter andadjusted or changed as required. NOTE: The anti-freeze solution contains a corro-sion inhibitor to prevent degradation of thealuminum castings contained within theengine. Therefore, never, drain the systemand refill with water only. In addition, anti-freeze solution must ALWAYS be used in vehicles fitted with air conditioning,to prevent the heater matrix from freezing andsubsequently bursting with the refrigerationsystem in use.

Engine Coolant Level
SG050D1-E
To Change the Engine Coolant The engine coolant should be changed at
those intervals specified in the vehicle main- tenance schedule in Section 5.
NOTE:Care should be taken to ensure that cool-
ant is not allowed to spill onto thepaintwork since the finish may becomedamaged. If coolant spillage occurs, theaffected area should be rinsed thoroughlywith water. The engine coolant level may be observed
through the side of the plastic coolant reservoir(expansion tank) when the engine is cold. If thelevel is below the "LOW" mark, add coolant ofthe correct concentration until the level is be-tween the "LOW" and "Full" marks. If the levelfalls below the "LOW" mark on a regular basisdespite being topped up, consult a Hyundaidealer. 1. Park the vehicle on level ground and en-
sure that the parking brake is firmly ap-plied, and the engine allowed to cool. DO NOT ATTEMPT THIS OPERATION WHILST THE ENGINE IS HOT SINCEBURNING OR SCALDING MAY RESULT.
2. Prepare a suitable receptacle to collect the displaced coolant and position this under theradiator drain tap.
3. With the heater temperature control set to the "HOT" position, remove the radiator capand open the radiator drain tap.
4. When the engine coolant has drained com- pletely, close the drain tap ensuring that thisis not over tightened.
5. Prepare a suitable quantity of new engine coolant (refer to section 9) and pour thisinto the radiator.
6. Start the engine with the radiator cap still removed and continue to add coolant as thelevel decreases as air is expelled from thesystem. When the level remains constant,replace the radiator cap and replenish thecoolant reservoir.
7. When the engine is hot, check to ensure that no coolant leaks are present.
WARNING: The cooling fan is controlled by engine coolant temperature and may sometimesoperate even when the engine is not run-ning. Use extreme caution when workingnear the blades of the cooling fan so that

NOTE: It is imperative that vehicles fitted with an
air conditioning system have a coolant concentration of the recommended strengthat all times. The use of the air conditioningsystem when the cooling system is filledwith water only will result in the heatermatrix freezing and subsequently bursting.
