DRIVING YOUR HYUNDAI

8. When parking your car and trailer, especially
on a hill, be sure to follow all the normal
precautions. Turn your front wheel into 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's tires.
9. If the trailer has electric brakes, start your
vehicle and trailer moving, and then apply the
trailer brake controller by hand to be sure the
brakes are working. This lets you check
your electrical connection at the same time.
10.During your trip, check occasionally to be
sure that the load is secure, and that the
lights and any trailer brakes are still working.
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 reduced 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 reduce speed
to reduce chances of engine overloading
and/or overheating.
CAUTION:
If overheating should occur when towing,
(the temperature gauge reads near red zone),
taking the following action may reduce or
eliminate 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 selector in park or neutral and idle
the engine at a higher speed.

hold the vehicle in place by pressing on the
accelerator. This can cause the automatic
transaxle to overheat. Use the parking brake
or footbrake.NOTE:When towing check transaxle fluid more
frequently.

34WHAT TO DO IN AN EMERGENCY
IF THE ENGINE OVERHEATS
!!
!
WARNING:
While the engine is running, keep hair,
hands and clothing away from moving parts
such as the fan and drive belts to prevent
injury.
5. If the water pump drive belt is broken or
engine coolant is leaking out, stop the engine
immediately and call the nearest Hyundai
dealer for assistance.
WARNING:
Do not remove the radiator cap when the
engine is hot. This can allow coolant to be
blown out of the opening and cause seri-
ous burns.6. If you cannot find the cause of the overheat-
ing, wait until the engine temperature has
returned to normal. Then, if coolant has been
lost, carefully add coolant to the reservoir
(page 6-9) to bring the fluid level in the
reservoir up to the halfway mark.
7. Proceed with caution, keeping alert for fur-
ther signs of overheating. If overheating
happens again, call a Hyundai dealer for
assistance.
CAUTION:
Serious loss of coolant indicates there is a
leak in the cooling system and this should
be checked as soon as possible by a Hyundai
dealer.
D030A02A-AATIf your temperature gauge indicates overheat-
ing, you experience a loss of power, or hear loud
pinging or knocking, the engine is probably too
hot. If this happens, you should:
1. Pull off the road and stop as soon as it is safe
to do so.
2. Place the gear selector lever in "P" (auto-
matic) or neutral (manual transaxle) and set
the parking brake. If the air conditioning is on,
turn it off.
3. If engine coolant is running out under the car
or steam is coming out from the hood, stop
the engine. Do not open the hood until the
coolant has stopped running or the steaming
has stopped. If there is no visible loss of
engine coolant and no steam, leave the
engine running and check to be sure the
engine cooling fan is operating. If the fan is
not running, turn the engine off.
4. Check to see if the water pump drive belt is
missing. If it is not missing, check to see that
it is tight. If the drive belt seems to be
satisfactory, check for coolant leaking from
the radiator, hoses or under the car. (If the
air conditioning had been in use, it is normal
for cold water to be draining from it when you
stop).

G020C01A-AATVehicle InteriorThe following should be checked each time
when the vehicle is driven:
o Lights operation
o Windshield wiper operation
o Horn operation
o Defroster, heating system operation (and air
conditioning, if installed)
o Steering operation and condition
o Mirror condition and operation
o Turn signal operation

If you notice anything that does not operate
correctly or appears to be functioning correctly,
inspect it carefully and seek assistance from
your Hyundai dealer if service is needed.
G020B01A-AATVehicle ExteriorThe following should be checked monthly:
o Overall appearance and condition
o Wheel condition and wheel nut torque
o Exhaust system condition

o Windshield glass condition
o Wiper blade condition
o Paint condition and body corrosion
o Fluid leaks
o Door and hood lock condition
o Tire pressure and condition
(including spare tire)GENERAL CHECKSG020A01NF-AATEngine CompartmentThe following should be checked regularly:
o Engine oil level and condition
o Transaxle fluid level and condition
o Brake fluid level
o Engine coolant level
o Windshield washer fluid level
o Accessory drive belt condition
o Engine coolant hose condition
o Fluid leaks (on or below components)
o Power steering fluid level

CHECKING THE ENGINE OILG030B01O-AATRecommended OilThe engine oil quality should meet the following
classification.
API SJ, SL or ABOVE,
ILSAC GF-3 or ABOVE
G030B01JM-U G030A01A-AAT
Engine oil is essential to the performance and
service of the engine. It is suggested that you
check the oil level at least once a week in normal
use and more often if you are on a trip or driving
in severe conditions.

DO-IT-YOURSELF MAINTENANCE

G050B01A-AATRecommended Engine CoolantUse a high quality ethylene-glycol coolant in a
50/50 mix with water. The engine coolant should
be compatible with aluminum engine parts.
Additional corrosion inhibitors or additives should
not be used. The cooling system must be
maintained with the correct concentration and
type of engine coolant to prevent freezing and
corrosion. Never allow the concentration of
antifreeze to exceed the 60% level or go below
the 35% level, or damage to the cooling system
may result. For proper concentration when
adding or replacing the engine coolant, refer to
the following table.

G050C01NF-GATTo Check the Coolant LevelThe coolant level can be seen on the side of the
plastic coolant reservoir. The level of the cool-
ant should be between the "L" and "F" lines on
the reservoir when the engine is warm with it at
idle . If the level is below the "L" mark, add engine
coolant to bring it up to "F". If the level is low,
inspect for coolant leaks and recheck the fluid
level frequently. If the level drops again, visit
your Hyundai dealer for an inspection and
diagnosis of the reason.
G050C01NFG050D01NF-GAT
To Change the Engine CoolantThe engine coolant should be changed at those
intervals specified in the vehicle maintenance
schedule in Section 5.
CAUTION:
o Engine coolant can damage the finish of
your car. If you spill engine coolant on
the car, wash it off thoroughly with clean
water.
o The engine in your vehicle has alumi-
num engine parts and must be protected
by an ethylene-glycol base coolant to
prevent corrosion and freezing.
Do not use hard water. Hard water can
cause engine damage from corrosion,
overheating or freezing.
!
1. Park the car on level ground, set the parking
brake and remove the radiator cap when
cool.
