DRIVING YOUR HYUNDAI 2- 13
4. To maintain engine braking efficiency andelectrical charging performance, do not use fifth gear (manual transaxle) or overdrive(automatic transaxle).
5. Always secure items in the trailer to prevent load shift while driving.
6. Check the condition and air pressure of all tires on the trailer and your car. Low tirepressure can seriously affect the handling.Also check the spare tire.
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 straight ahead.If there is too much wind buffeting slowdown to get out of the other vehicle's airturbulence.
8. When parking your car and trailer, especial- ly on a hill, be sure to follow all the normalprecautions. Turn your front wheel into thecurb, set the parking brake firmly, and putthe transaxle in 1st or Reverse (manual) orPark (automatic). In addition, place wheelchocks at each of the trailer's tires.
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 the sametime.
10. During your trip, check occasionally to be sure that the load is secure, and that thelights and any trailer brakes are still working.
WARNING:
o The tongue load should never exceed;
Auto: 25kgManual : 28kg

After Changing Wheels
If you have a tire gauge, remove the valve cap
and check the air pressure. If the pressure is lower than recommended, drive slowly to thenearest service station and inflate to the correctpressure. If it is too high, adjust it until it iscorrect. Always reinstall the valve cap afterchecking or adjusting tire pressure. If the cap isnot replaced, air may leak from the tire. If youlose a valve cap, buy another and install it assoon as possible.
After you have changed wheels, always secure
the flat tire in its place in the luggage room andreturn the jack and tools to their proper storagelocations. D080A01A-GAT
IF YOUR CAR MUST BE TOWED D080B01A-AAT
Towing a Car With a Manual Transaxle
o OK FOR AUTOMATIC OR MANUAL TRANSAXLE EQUIPPED VEHICLE WITH NO DAMAGE
o OK FOR AUTOMATIC OR MANUAL
TRANSAXLE EQUIPPED VEHICLE
CAUTION: Your car can be damaged if towed incor- rectly! If your car has to be towed, it should be done by
your Hyundai dealer or a commercial tow truckservice. This will help assure that your car isnot damaged in towing. Also, professionals aregenerally aware of state and local laws govern-ing towing. In any case, rather than risk dam-age to your car, it is suggested that you showthis information to the tow truck operator. Besure that a safety chain system is used and thatlocal laws are observed. o If the car is being towed with the rear wheels
on the ground, be sure the parking brake isreleased.
o If the car is being towed with the front wheels on the ground, be sure that thetransaxle is in neutral. Also, be sure that theignition key is in the "ACC" position. This isnecessary to prevent damage to the steer-ing lock mechanism, which is not designedto hold the front wheels straight while the caris being towed.
o If any of the loaded wheels or suspension components are damaged, a towing dollymust be used.

EXPLANATION OF SCHEDULED MAIN- TENANCE ITEMS
F060M01A-AAT
o Engine oil and filter The engine oil and filter should be changed at
the intervals specified in the maintenance sched- ule. If the car is being driven in severe condi-tions, more frequent oil and filter changes arerequired.
F060B01A-AAT
o Drive belts
Inspect all drive belts for evidence of cuts,
cracks, excessive wear or oil and replace ifnecessary. Drive belts should be checked pe-
riodically for proper tension and adjusted asnecessary.
F060C01A-GAT
o Fuel filter
A clogged filter can limit the speed at which the
vehicle may be driven, damage the emissionsystem and cause hard starting. If an exces-sive amount of foreign matter accumulates inthe fuel tank, the filter may require replacementmore frequently.
After installing a new filter, run the engine for
several minutes, and check for leaks at theconnections. F060D01A-GAT
o Fuel lines, fuel hoses and connec-
tions
Check the fuel lines, fuel hoses and connec-
tions for leakage and damage. Replace anydamaged or leaking parts immediately. Inspect the hose routing to assure that the
hoses do not come in contact with any heatsource, sharp edges or moving component
which might cause heat damage or mechanicalwear. Inspect all hose connections, such as
clamps and couplings, to make sure they aresecure, and that no leaks are present. Hoses
should be replaced immediately if there is any
evidence of deterioration or damage.
