WHAT TO DO IN AN EMERGENCY
D080D03A-AATEMERGENCY TOWING
For emergency towing when no commercial tow
vehicle is available, attach a tow cable, chain or
strap to one of the towing hooks under the front/
rear of your car. Do not attempt to tow your
vehicle in this manner on any unpaved surface.
This may result in serious damage to your car.
Nor should it be attempted if the wheels, drive
train, axles, steering or brakes are damaged.
Before towing, be sure the transaxle is in neutral
and the key in "ACC" (with the engine off) or in
the "ON" position (with the engine running). A
driver must be in the towed car to steer it and
operate the brakes.
HLC4014NOTE:Before towing, check the level of the tran-
saxle fluid. If it is below the "HOT" range on
the dipstick, add fluid. If you cannot add
fluid, a towing dolly must be used as de-
scribed above.

never be towed from the rear with the front
wheels on the ground. This can cause seri-
ous damage to the transaxle. If the car must
be towed from the rear, a towing dolly must
be used under the front wheels. o NOT OK FOR AUTOMATIC

5VEHICLE MAINTENANCE REQUIREMENTS
2MAINTENANCE INTERVALS
F010B01A-AAT
Maintenance Requirements
The maintenance required for your Hyundai can
be divided into three main areas:
o Specified scheduled procedures
o General checks
o Do-it-yourself maintenance
F010A01A-AAT
Service Requirements
To ensure that you receive the greatest number
of miles of satisfying operation from your
Hyundai, certain maintenance procedures must
be performed. Although careful design and engi-
neering have reduced these to a minimum,
those that are required are of the utmost impor-
tance.
It is your responsibility to have these mainte-
nance procedures performed to comply with the
terms of the warranties covering your new
Hyundai. The Owner's Handbook supplied with
your new vehicle provides further information
about these warranties.
F010D01A-AAT
General Checks
These are the regular checks you should per-
form when you drive your Hyundai or you fill the
fuel tank. A list of these items will be found on
page 6-3.
F010C01A-AAT
Specified Scheduled Procedures
These are the procedures such as inspections,
adjustments and replacements that are listed in
the maintenance charts starting on page 5-4.
These procedures must be performed at the
intervals shown in the maintenance schedule to
assure that your warranty remains in effect.
Although it is strongly recommended that they
be performed by the factory-trained or distribu-
tor-trained technicians at your Hyundai dealer,
these procedures may be performed at any
qualified service facility.
It is suggested that genuine Hyundai service
parts be used for any required repairs or re-
placements. Other parts of equivalent quality
such as engine oil, engine coolant, manual or
auto transaxle oil, brake fluid and so on which
are not supplied by Hyundai Motor Company or
its distributor may be used without affecting your
warranty coverage but you should always be
sure these are equivalent to the quality of the
original Hyundai parts. Your Owner's Handbook
provides further information about your warranty
coverage.
F010E01A-AAT
Do-It-Yourself Maintenance
If 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 your-
self, see Section 6.

5VEHICLE MAINTENANCE REQUIREMENTS
7EXPLANATION OF SCHEDULED
MAINTENANCE ITEMS
F060D01A-AAT
o Fuel Lines, Fuel Hoses and
Connections
Check the fuel lines, fuel hoses and connec-
tions for leakage and damage. Have a trained
techincian, replace any damaged or leaking
parts immediately.
F060C01A-AATo Fuel Filter
A clogged filter can limit the speed at which the
vehicle may be driven, damage the emission
system and cause hard starting. If an excessive
amount of foreign matter accumulates in the fuel
tank, the filter may require replacement more
frequently.
After installing a new filter, run the engine for
several minutes, and check for leaks at the
connections.
Fuel filters should be installed by trained techni-
cians.
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 are
required.

inspected at those intervals specified in the
maintenance schedule. Make sure that a new
vapor hose or fuel filler cap is correctly re-
placed.
F060F01A-AATo Vacuum, Crankcase Ventilation
Hoses
Inspect the surface of hoses for evidence of
heat and/or mechanical damage. Hard and brittle
rubber, cracking, tears, cuts, abrasions, and
excessive swelling indicate deterioration. Par-
ticular attention should be paid to examine those
hose surfaces nearest to high heat sources,
such as the exhaust manifold.
Inspect the hose routing to assure that the
hoses do not come in contact with any heat
source, sharp edges or moving component which
might cause heat damage or mechanical wear.
Inspect all hose connections, such as clamps
and couplings, to make sure they are secure,
and that no leaks are present. Hoses should be
replaced immediately if there is any evidence of
deterioration or damage.
F060B01A-AAT

4CHECKING THE ENGINE OIL
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.
G030B01A-AATRecommended Oil
SH, SG or SG/CD (API) multi-grade and fuel
efficient oil is recommended.
G030A02AG030C02A-AAT
To Check the Oil Level
Before checking the oil, warm up the engine to
the normal operating temperature and be sure it
is parked on level ground. Turn the engine off.
Wait five minutes, then remove the dipstick,
wipe it off, fully reinsert the dipstick and with-
draw it again. Then note the highest level the oil
has reached on the dipstick. It should be be-
tween the upper ("F") and lower ("L") range.
G030D01A-AAT
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 counter-
clockwise.
2. Add oil, then check the level again. Do not
overfill.
3. Replace the cap by turning it clockwise.
The distance between the "F" and "L" marks is
equal to about 1 quart of oil.
