TRANSAXLE EQUIPPED VEHICLE D080C01LD080D02A-GAT EMERGENCY TOWING
For emergency towing when no com- mercial tow vehicle is available, attacha tow cable, chain or strap to one of thetie-down hooks under the front of your car. Do not attempt to tow your vehicle in this manner on any unpaved sur-face. This could result in serious dam-age to your car.Nor should towing be attempted if thewheels, drive train, axles, steering or brakes are damaged. Before towing, be sure the transaxle is in neutral andthe key is in "ACC" (with the engine off)or in the "ON" position (with the enginerunning). A driver must be in the towedcar to steer it and operate the brakes. D080D01L
CAUTION:
If the car is being towed with all fourwheels on the ground, it can betowed only from the front. Be surethat the transaxle is in neutral. Do not tow at speeds greater than 50 km/h (30 mph) and for more than 25km (15 miles).Be sure the steering is unlocked byplacing the key in the "ACC" posi-tion. A driver must be in the towed vehicle to operate the steering and brakes.

Maintenance Requirements
The maintenance required for yourHyundai can be divided into threemain areas:
o Specified scheduled procedures
o General checks
o Do-it-yourself maintenance It is suggested that genuine Hyundai service parts be used for any requiredrepairs or replacements. Other parts ofequivalent quality such as engine oil,engine coolant, manual or auto transaxle oil, brake fluid and so on
which are not supplied by HyundaiMotor Company or its distributor maybe used without affecting your war-ranty coverage but you should al-ways be sure these are equivalent to the quality of the original Hyundai parts. Your Service Passport providesfurther information about your war-ranty coverage.

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 bepaid to examine those hose surfacesnearest to high heat sources, such asthe exhaust manifold. Inspect the hose routing to assure
that the hoses do not come in contactwith any heat source, sharp edges ormoving component which might cause heat damage or mechanical wear. Inspect all hose connections, such asclamps and couplings, to make surethey are secure, and that no leaks arepresent. Hoses should be replacedimmediately if there is any evidence of deterioration or damage.

G030A01A-AAT CHECKING THE ENGINE OIL Engine oil is essential to the perfor- mance and service of the engine. It is suggested that you check the oil level at least once a week in normal useand more often if you are on a trip or driving in severe conditions. G030B01A-GAT Recommended Oil
G030B01L
SH, SG or SG/CD (API) multi-grade and fuel efficient oil is recommended. NOTE: SAE 5W-20 is not recommended for sustained high speed vehicle operation.G030C01A-AAT
To Check the Oil Level
Before checking the oil, warm up the
engine to the normal operating tem- perature and be sure your car is parked on level ground. Turn the en-gine off.
Wait a minute, then remove the dip-
stick, wipe it off, fully reinsert thedipstick and withdraw it again. Thennote the highest level the oil has reached on the dipstick. It should be between the upper ("FULL") and lower("LOW") range. HXG094J
G030D01A-GAT
Adding Oil
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 counterclockwise.
2. Add oil, then check the level again. Do not overfill.
3. Replace the cap by turning it clock- wise.
The distance between the "F" and "L"
marks is equal to about 1 liter of oil.
