SUN-VISOR
Sun visors are fitted to both the driver and
passenger side of the vehicle. Certain deriva- tives are equipped with a vanity mirror whichis located on the back of the driver andpassenger visor. The visor may be lowered toreduce the amount of glare from directly ahead,or may be moved towards the side window toreduce glare from the side of the vehicle, oncethe inner pivot has been unclipped from thebracket.
NOTE: The Supplemental Restraint System (SRS)
label containing useful information can be found on the back of each sun visor.
WARNING: Do not place the sun-visor in such a man-
ner that it obscures visibility of the road- way, traffic or other objects. SB520A1-F STEERING WHEEL TILT LEVER

To adjust the steering wheel:
1. Push the lever downward to unlock.
2. Raise or lower the steering wheel to the
desired position.
3. After adjustment, securely tighten the lever by pulling it upward
WARNING: Do not attempt to adjust the steering wheel
while driving as this may result in loss ofcontrol of the vehicle and result in death orserious injury.

DRIVING YOUR HYUNDAI 2- 15
5. Always secure items in the trailer to pre-
vent load shift while driving.
6. Check the condition and air pressure of all tyres on the trailer and your car. Low tyre pressure can seriously affect the handling.Also check the spare tyre.
7. The vehicle/trailer combination is more af- fected by crosswind and buffeting. When being passed by a large vehicle, keep a constant speed and steer straightahead. If there is too much wind buffetingslow down to get out of the other vehicle'sair turbulence.
8. When parking your car and trailer, espe- cially on a hill, be sure to follow all thenormal precautions. Turn your front wheelinto the curb, set the parking brake firmly,and put the transaxle in 1st or Reverse(manual) or Park (automatic). In addition,place wheel chocks at each of the trailer'styres.
9. If the trailer has electric brakes, start your vehicle and trailer moving, and then applythe trailer brake controller by hand to besure the brakes are working. This lets youcheck your electrical connection at thesame time.
10.During your trip, check occasionally to be sure that the load is secure, and that thelights and any trailer brakes are still work-ing. 11.Avoid jerky starts, sudden acceleration or
sudden stops.
12.Avoid sharp turns and rapid lane changes.
13.Avoid holding the brake pedal down too long or too frequently. This could cause the brakes to overheat, resulting in re-duced braking efficiency.
14.When going down a hill, shift into a lower gear and use the engine braking effect. When ascending a long grade, downshift the transaxle to a lower gear and reducespeed to reduce chances of engine over-loading and/or overheating.
15.If you have to stop while going uphill, do not hold the vehicle in place by pressing onthe accelerator. This can cause the auto-matic transaxle to overheat. Use the park-ing brake or footbrake.
NOTE: When towing check transaxle fluid more frequently. CAUTION: If overheating should occur when towing,(temperature gauge reads near red zone),taking the following action may reduce oreliminate the problem.
1. Turn off the air conditioner.
2. Reduce highway speed.
3. Select a lower gear when going uphill.
4. While in stop and go traffic, place the gear selection in park or neutral and idle the engine at a higher speed.

IN CASE OF EMERGENCY
WARNING: While the engine is running, keep hands
and clothing away from moving parts such as the fan and drive belts to preventinjury.
WARNING (Diesel only): Never work on injection system with en-
gine running or within 30 seconds after shutting off engine. High pressure pump,rail, injectors and high pressure pipes aresubject to high pressure even after theengine stopped. The fuel jet produced byfuel leaks may cause serious injury, if ittouch the body. People using pacemak-ers should not move than 30cm closer tothe ECU or wiring harness within theengine room while engine is running,since the high currents in the CommonRail system produce considerable mag-netic fields.
5. If the water pump drive belt is broken or coolant is leaking out, stop the engine immediately and call the nearest Hyundaidealer for assistance.
WARNING: Do not remove the radiator cap when the
engine is hot since steam and boiling wa- ter may be ejected from the radiator result-ing in burns or scalding. D040A01FC-EAT TEMPORARY SPARE TYREThe following instructions for the temporary spare tyre should be observed:
1. Check inflation pressure as soon as pos-
sible after installing the spare tyre, and adjust to the specified pressure. The tyrepressure should be periodically checkedand maintained at the specified pressurewhile the tyre is stored. 2. The spare tyre should only be used tem-
porarily and should be returned to theluggage compartment as soon as the origi-nal tyre can be repaired or replaced.
3. Continuous use at speeds of over 80 km/h (50 mph) is not recommended.
4. As the temporary spare tyre is specifically designed for your car, it should not beused on any other vehicle.
5. The temporary spare tyre should not be used on any other wheels, nor shouldstandard tyre, snow tyre, wheel covers ortrim rings be used with the temporaryspare wheel. If such use is attempted,damage to these items or other car com-ponents may occur.
6. The temporary spare tyre pressure should be checked once a month while the tyre isstored.
CAUTION:
o Do not use snow chains with your tem- porary spare tyre.
o Do not use more than one temporary spare tyre at a time.
Spare Tyre Pressure
Type Size Inflation Pressure T115/70R(D)15420 kPa (60 psi)6. If the cause of the overheating cannot be
found, wait until the engine temperature has returned to normal. Then, if coolanthas been lost, carefully remove the radia-tor cap and add water to bring the fluid levelin the reservoir up to the base of theradiator fill opening. Fill the coolant expan-sion tank to the halfway mark.
7. Proceed with caution until it is established that the engine is operating normally. If theengine overheats repeatedly, the advice ofa Hyundai dealer should be sought.
CAUTION: Serious loss of coolant indicates there is a leak in the cooling system and thisshould be checked as soon as possibleby a Hyundai dealer.

SD080A1-E
VEHICLE TOWING OR RECOVERY
The pressure of the spare tyre should be checked at the first available opportunity. Ifany doubt exists as to the tyre pressure, thevehicle should be driven slowly to the nearestservice station and the tyre pressure checkedand adjusted as required. If the valve cap is lost from any of the valves, a replacement should be obtained and fittedat the first available opportunity. The valvecap prevents the ingress of dirt which maycause the valve to stick and therefore leakand is part of the valve sealing function. Ensure that the spare wheel, jack and wheel nut wrench as well tools are correctly locatedin the boot of the vehicle to prevent damageand noise. CAUTION:
An incorrect tow or recovery could result
in serious damage to the vehicle. If anydamage to the suspension, steering ortransaxle is apparent or suspected, a tow-ing ambulance must be used.

WARNING (Diesel only): Never work on injection system with en-gine running or within 30 seconds aftershutting off engine. High pressure pump,rail, injectors and high pressure pipes aresubject to high pressure even after theengine stopped. The fuel jet produced byfuel leaks may cause serious injury, if ittouch the body. People using pacemak-ers should not move than 30cm closer tothe ECU or wiring harness within theengine room while engine is running,since the high currents in the CommonRail system produce considerable mag-netic fields. 6ZF060E1-A
o Timing belt Replace timimg belt and inspect all associated parts related for damage and deformation.Replace any damaged parts immediately. 6ZF060G1-A
o Vapour hose and fuel filler cap The vapour hose and fuel filler cap should be inspected at those intervals specified in themaintenance schedule. Make sure that a newvapour hose or fuel filler cap is correctlyreplaced. 6ZF060F1-A
o Vacuum, crankcase
ventilation hoses
Inspect the surface of hoses for evidence of heat and/or mechanical damage. Hard andbrittle rubber, cracking, tears, cuts, abra-sions, and excessive swelling indicate dete-rioration. Particular attention should be paid toexamining those hose surfaces nearest tohigh heat sources, such as the exhaustmanifold.Inspect the hose routing to assure that thehoses do not come in contact with any heatsource, sharp edges or moving componentwhich might cause heat damage or mechani-cal wear. Inspect all hose connections, suchas clamps and couplings, to make sure theyare secure, and that no leaks are present.Hoses should be replaced immediately if thereis any evidence of deterioration or damage.

Brake Fluid Level
The fluid level in the brake fluid reservoir
should be checked periodically. The levelshould be between the "MIN" and "MAX"marks on the side of the reservoir. If the levelis at or below the "MIN" mark, fluid should beadded having carefully cleaned the area sur-rounding the reservoir cap to ensure that dirtis not allowed to enter the system. It shouldbe borne in mind that the brake fluid level willdecrease slightly as the friction linings of thepads and shoes become worn and that this isa normal condition.

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 thatyou are not injured by a rotating fan blade.As the engine coolant temperature de-creases, the fan will automatically shutoff. This is a normal condition.
WARNING (Diesel only): Never work on injection system with en-
gine running or within 30 seconds after shutting off engine. High pressure pump,rail, injectors and high pressure pipes aresubject to high pressure even after theengine stopped. The fuel jet produced byfuel leaks may cause serious injury, if it touch the body. People using pacemak-ers should not move than 30cm closer tothe ECU or wiring harness within theengine room while engine is running,since the high currents in the CommonRail system produce considerable mag-netic fields.
