DRIVING YOUR HYUNDAI
23
8. When parking your car and trailer, es-
pecially 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, down-
shift the transaxle to a lower gear and
reduce speed to reduce chances of
engine overloading and/or overheat-
ing.
CAUTION:
If overheating should occur when tow-
ing, (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.

15. If you have to stop while going uphill,
do not hold the vehicle in place by
pressing on the accelerator. This can
cause the automatic transaxle to over-
heat. 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 se-
rious 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
further 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 over-
heating, 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"
(automatic) 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).

CORROSION PREVENTION AND APPEARANCE CARE2
CORROSION PROTECTION
E020B01A-AATKeep Your Car CleanThe best way to prevent corrosion is to
keep your car clean and free of corrosive
materials. Attention to the underside of the
car is particularly important.
o If you live in a high-corrosion area —
where road salts are used, near the
ocean, areas with industrial pollution,
acid rain, etc.—, you should take extra
care to prevent corrosion. In winter,
hose off the underside of your car at
least once a month and be sure to clean
the underside thoroughly when winter
is over.
o When cleaning underneath the car, give
particular attention to the components
under the fenders and other areas that
are hidden from view. Do a thorough
job; just dampening the accumulated
mud rather than washing it away will
accelerate corrosion rather than prevent
it. Water under high pressure and steam
are particularly effective in removing
accumulated mud and corrosive
materials.E020A01A-AATYou can help prevent corrosion from getting
started by observing the following:
E010D01A-AATMoisture Breeds CorrosionMoisture creates the conditions in which
corrosion is most likely to occur. For
example, corrosion is accelerated by high
humidity, particularly when temperatures
are just above freezing. In such conditions,
the corrosive material is kept in contact
with the car surfaces by moisture that is
slow to evaporate.
Mud is particularly corrosive because it is
slow to dry and holds moisture in contact
with the vehicle. Although the mud appears
to be dry, it can still retain the moisture and
promote corrosion.
High temperatures can also accelerate
corrosion of parts that are not properly
ventilated so the moisture can be dispersed.
For all these reasons, it is particularly
important to keep your car clean and free
of mud or accumulations of other materials.
This applies not only to the visible surfaces
but particularly to the underside of the car.E010C01A-AATHigh-Corrosion AreasIf you live in an area where your car is
regularly exposed to corrosive materials,
corrosion protection is particularly
important. Some of the common causes of
accelerated corrosion are road salts, dust
control chemicals, ocean air and industrial
pollution.
E010B01A-AATCommon Causes of CorrosionThe most common causes of corrosion on
your car are:
o Road salt, dirt and moisture that is
allowed to accumulate underneath the
car.
o Removal of paint or protective coatings
by stones, gravel, abrasion or minor
scrapes and dents which leave
unprotected metal exposed to corrosion.E010A01A-AATProtecting Your Hyundai from Cor-
rosionBy using the most advanced design and
construction practices to combat corrosion,
Hyundai produces cars of the highest
quality. However, this is only part of the job.
To achieve the long-term corrosion
resistance your Hyundai can deliver, the
owner's cooperation and assistance is also
required.

WASHING AND WAXING
E020E01A-AATDon't Neglect the InteriorMoisture can collect under the floor mats
and carpeting to cause corrosion. Check
under the mats periodically to be sure the
carpeting is dry. Use particular care if you
carry fertilizers, cleaning materials or
chemicals in the car.
These should be carried only in proper
containers and any spills or leaks should
be cleaned up, flushed with clean water
and thoroughly dried.
E020C01A-AATKeep Your Garage DryDon't park your car in a damp, poorly
ventilated garage. This creates a favorable
environment for corrosion. This is
particularly true if you wash your car in the
garage or drive it into the garage when it is
still wet or covered with snow, ice or mud.
Even a heated garage can contribute to
corrosion unless it is well ventilated so
moisture is dispersed.
E030A02A-AATWashing Your HyundaiNever wash your car when the surface is
hot from being in the sun. Always wash
your car in the shade.
Wash your car frequently. Dirt is abrasive
and can scratch the paint if it is not removed.
Air pollution or acid rain may damage the
paint and trim through chemical action if
pollutants are allowed to remain in contact
with the surface. If you live near the ocean
or in an area where road salts or dust
control chemicals are used, you should
pay particular attention to the underside of
the car. Start by rinsing the car to remove
dust and loose dirt. In winter, or if you have
driven through mud or muddy water, be
sure to thoroughly clean the underside as
well. Use a hard direct stream of water to
remove accumulations of mud or corrosive
materials. Use a good quality car-washing
solution and follow the manufacturer's
directions on the package. These are
available at your Hyundai dealer or auto
parts outlet. Don't use strong household
detergents, gasoline, strong solvents or
abrasive cleaning powders as these may
damage the finish.
Use a clean sponge or cloth, rinse it
frequently and don't damage the finish by
rubbing too hard. For stubborn spots,
dampen them frequently and remove them
a little at a time. o When cleaning lower door panels,
rocker panels and frame members, be
sure that drain holes are kept open
so that moisture can escape and not
be trapped inside to ac-celerate
corrosion.
E020D02A-AATKeep Paint and Trim in Good
ConditionScratches or chips in the finish should be
covered with "touch-up" paint as soon as
possible to reduce the possibility of
corrosion. If bare metal is showing through,
the attention of a qualified body and paint
shop is recommended.
Bird droppings : Bird droppings are highly
corrosive and may damage painted
surfaces in just a few hours. Always remove
bird droppings as soon as possible.

SCHEDULED MAINTENANCE
REQUIREMENTSF020A02Y-AATo Inspection should be performed any
time a malfunction is experienced or
suspected.
o Receipts for all emission control system
services should be retained to
demonstrate compliance with
conditions of the emissions system
warranty.
o After 120 months or 150,000 miles
(240,000 km), continue to follow the
prescribed maintenance intervals.
o For severe usage maintenance require-
ments, see page 5-6 of this section.
F010D02A-AATGeneral ChecksThese are the regular checks you should
perform when you drive your Hyundai or
you fill the fuel tank. A list of these items will
be found on page 6-4.F010E01A-AATDo-It-Yourself MaintenanceIf you are mechanically inclined, own a few
tools that are required and want to take the
time to do so, you can inspect and service
a number of items. For more information
about doing it yourself, see Section 6.
F010F01A-AATA Few Tipso Whenever you have your Hyundai
serviced, keep copies of the service
records in your glove box. This will help
ensure that you can document that the
required procedures have been
performed to keep your warranties in
effect. This is especially important when
service is not performed by an authorized
Hyundai dealer.
o If you choose to do your own
maintenance and repairs, you may find
it helpful to have an official Hyundai
Shop Manual. A copy of this publication
may be purchased at your Hyundai
dealer's parts department.
