C160H01A-AAT Use Approved Anti-Freeze in Window Washer System To keep the water in the window washer system from freezing, add an approvedanti-freeze solution in accordance with instructions on the container. Window washer anti-freeze is available fromHyundai dealers and most auto parts outlets. Do not use engine coolant or other types of anti-freeze as thesemay damage the finish.
C160G02A-GAT To Keep Locks from Freezing To keep the locks from freezing, squirt an approved de-icer fluid or glycerineinto the key opening. If a lock is cov- ered with ice, squirt it with an approved de-icing fluid to remove the ice. If thelock is frozen internally, you may be able to thaw it out by using a heated key. Handle the heated key with careto avoid injury. NOTE: The proper temperature for using the immobilizer key is from -40°C (- 40°F) to 80°C(176°F). If you heat the immobilizer key over 80°C to openthe frozen lock, it may cause dam- age to the transponder in its head.
C160D01A-AAT Check Battery and Cables Winter puts additional burdens on the battery system. Visually inspect thebattery and cables as described in Section 6. The level of charge in your battery can be checked by your Hyundaidealer or a service station. C160F01A-AAT Check Spark Plugs and Ignition System Inspect your spark plugs as described in Section 6 and replace them if neces-sary. Also check all ignition wiring and components to be sure they are not cracked, worn or damaged in any way.
C160E01A-AAT Change to "Winter Weight" Oil if Necessary In some climates it is recommended that a lower viscosity "winter weight" oil be used during cold weather. See Section 9 for recommendations. If youaren't sure what weight oil you should use, consult your Hyundai dealer.

3 WHAT TO DO IN AN EMERGENCY

!
IF THE ENGINE WILL NOT START
D010A01A-AAT D010B02A-AAT
If Engine Doesn't Turn Over or Turns Over Slowly
1. If your car has an automatic transaxle, be sure the gear selector lever is in "N" or "P" and the emer-gency brake is set.
2. Check the battery connections to be
sure they are clean and tight.
3. Turn on the interior light. If the light dims or goes out when you operatethe starter, the battery is discharged.
4. Check the starter connections to be sure they are securely tightened.
5. Do not push or pull the vehicle to start it. See instructions for "Jump Starting". D010C01A-AAT If Engine Turns Over Normally but Does Not Start
D010B02E
WARNING:
If the engine will not start, do not push or pull the car to start it. This could result in a collision or causeother damage. In addition, push or pull starting may cause the cata- lytic converter to be overloaded andcreate a fire hazard.
1. Check fuel level.2. With the key in the "OFF" position,check all connectors at ignition coilsand spark plugs(For Gasoline En-gine) or check all connectors at glow plug and glow plug relay(For Diesel Engine). Reconnect any thatmay be disconnected or loose.
3. Check fuel line in the engine room.4. If engine still refuses to start, call a
Hyundai dealer or seek other quali- fied assistance. D010C01E

F060H01A-AAT
o Air Cleaner Filter A Genuine Hyundai air cleaner filter is
recommended when the filter is re- placed. F060J01A-AAT
o Spark Plugs Make sure to install new spark plugs of the correct heat range. F070B01A-GAT
o Cooling System Check the cooling system part, such as radiator, coolant reservoir, hosesand connections for leakage and dam- age. Replace any damaged parts.
F060E01A-AAT
o Timing Belt
Inspect all parts related to the timing belt for damage and deformation. Replace any damaged parts immedi- ately. F060G01A-AAT
o Vapor Hose and Fuel Filler Cap
The vapor hose and fuel filler cap should be inspected at those inter- vals specified in the maintenanceschedule. Make sure that a new va- por hose or fuel filler cap is correctly replaced. F060F01A-AAT
o Vacuum, Crankcase Ventila-
tion Hoses
Inspect the surface of hoses for evi-
dence of heat and/or mechanical dam- age. Hard and brittle rubber, crack- ing, tears, cuts, abrasions, and ex-cessive swelling indicate deteriora- tion. Particular attention should be paid to examine those hose surfacesnearest to high heat sources, such as the exhaust manifold.
Inspect the hose routing to assure that
the hoses do not come in contact withany heat source, sharp edges or mov- ing component which might cause heatdamage or mechanical wear. Inspect all hose connections, such as clamps and couplings, to make sure they aresecure, and that no leaks are present. Hoses should be replaced immedi- ately if there is any evidence of dete-rioration or damage. F060N02E-GAT
o Valve Clearance
Inspect excessive valve noise and/or engine vibration and adjust if neces- sary. A qualified technician shouldperform the operation.

SPARK PLUGS
G060A01L
G060B02S-GAT
REPLACING THE SPARK PLUGS (Gasoline Engine)
The spark plugs should be changed
at the intervals specified in the ve- hicle maintenances schedule in Sec- tion 5 or whenever engine perfor-mance indicates they should be changed. Symptoms that suggest poor spark plug performance include en-gine misfiring under load, loss of fuel economy, poor acceleration, etc. When spark plugs are replaced, al-ways use spark plugs recommended by Hyundai. The use of other spark plugs can result in loss of perfor-mance, radio interference or engine damage.Unleaded: 1.0 ~ 1.1 mm (0.039 ~ 0.043 in.) Leaded: 0.7 ~ 0.8 mm (0.028 ~ 0.032 in.)
NOTE: When replacing the spark plugs, genuine Hyundai replacement partsare recommended. Recommended Spark Plugs:

WARNING:
The cooling fan is controlled by engine coolant temperature and may sometimes operate even when theengine is not running. Use extreme caution when working near the blades of the cooling fan so thatyou are not injured by a rotating fan blade. As the engine coolant tem- perature decreases, the fan will au-tomatically shut off. This is a nor- mal condition.

!WARNING:
It is recommended that the engine
be cool or cold when changing the spark plugs. If the engine is hot, you could burn yourself on theinsulated connector, the spark plugs or the engine itself. HGK2574. When preparing to remove the old
spark plug, guide the socket down over the spark plug, being careful not to damage the ceramic insula- tor.
5. To remove the spark plug, turn the wrench handle in a counterclock-wise direction.
6. To install the new spark plug, guide
the socket down over the sparkplug, being careful not to damage the ceramic insulator.
HGK258
3. To remove the spark plug cable,
pull straight up on the insulated connector, not the cable. Pulling on the cable may damage the car- bon core conductor.
G060C01S-GAT Changing the Spark Plugs You will find it easier to change spark plugs if the engine is cold. Always change one spark plug at a time. This helps avoid getting the wires mixedup.
1. Remove the center cover on the
engine rocker cover.
2. Using a clean cloth, remove any dirt that has accumulated around the spark plug so it cannot fall intothe cylinder when the spark plug is removed. HGK256
