12DRIVING FOR ECONOMY
!WARNING:ABS will not prevent accidents due to
improper or dangerous driving maneu-
vers. Even though vehicle control is im-
proved during emergency braking, always
maintain a safe distance between you and
objects ahead. Vehicle speeds should al-
ways be reduced during extreme road
conditions.
The braking distance for cars equipped
with an anti-lock braking system may be
longer than for those without it in the
following road conditions.
During these conditions the veicle should
be driven at reduced speeds.
o Rough, gravel or snow-covered roads.
o With tire chains installed.
o On roads where the road surface is
pitted or has different surface height.
These roads should be driven at reduced
speeds. The safety features of an ABS
equipped vehicle should not be tested by
high speed driving or cornering. This could
endanger the safety of yourself or others.
C140A01A-AAT
You can save fuel and get more miles from
your car if you follow these suggestions:
o Drive smoothly. Accelerate at a moderate
rate. Don't make "jack-rabbit" starts or full-
throttle shifts and maintain a steady cruising
speed. Don't race between stoplights. Try to
adjust your speed to that of the other traffic
so you don't have to change speeds unnec-
essarily. Avoid heavy traffic whenever possi-
ble. Always maintain a safe distance from
other vehicles so you can avoid unneces-
sary braking. This also reduces brake wear.
o Drive at a moderate speed. The faster you
drive, the more fuel your car uses. Driving at
a moderate speed, especially on the high-
way, is one of the most effective ways to
reduce fuel consumption.
o Don't "ride" the brake or clutch pedal. This
can increase fuel consumption and also in-
crease wear on these components. In addi-
tion, driving with your foot resting on the
brake pedal may cause the brakes to over-
heat, which reduces their effectiveness and
may lead to more serious consequences.
o Take care of your tires. Keep them inflated to
the recommended pressure. Incorrect infla-
tion, either too much or too little, results in
unnecessary tire wear. Check the tire pres-
sures at least once a month.o Be sure that the wheels are aligned cor-
rectly. Improper alignment can result from
hitting curbs or driving too fast over irreg-
ular surfaces. Poor alignment causes faster
tire wear and may also result in other
problems as well as greater fuel consump-
tion.
o Keep your car in good condition. For better
fuel economy and reduced maintenance
costs, maintain your car in accordance with
the maintenance schedule in Section 5. If
you drive your car in severe conditions, more
frequent maintenance is required (see Sec-
tion 5 for details).
o Keep your car clean. For maximum service,
your Hyundai should be kept clean and free
of corrosive materials. It is especially impor-
tant that mud, dirt, ice, etc. not be allowed to
accumulate on the underside of the car. This
extra weight can result in increased fuel
consumption and also contribute to corro-
sion.
o Travel lightly. Don't carry unnecessary weight
in your car. Weight reduces fuel economy.
o Don't let the engine idle longer than neces-
sary. If you are waiting (and not in traffic),
turn off your engine and restart only when
you're ready to go.

o Remember, your Hyundai does not require
extended warm-up. As soon as the engine
is running smoothly, you can drive away. In
very cold weather, however, give your en-
gine a slightly longer warm-up period.
o Don't "lug" or "over-rev" the engine. Lug-
ging is driving too slowly in too high a gear
resulting in the engine bucking. If this hap-
pens, shift to a lower gear. Over-revving is
racing the engine beyond its safe limit. This
can be avoided by shifting at the recom-
mended speeds.
o Use your air conditioning sparingly. The air
conditioning system is operated by engine
power so your fuel economy is reduced
when you use it.
WINTER DRIVINGSMOOTH CORNERING
C160A01A-AAT
The more severe weather conditions of winter
result in greater wear and other problems. To
minimize the problems of winter driving, you
should follow these suggestions:
C160B01A-AATSnowy or Icy Conditions
To drive your vehicle in deep snow, it may be
necessary to use snow tires or to install tire
chains on your tires. If snow tires are needed, it
is necessary to select tires equivalent in size
and type to the original equipment tires. Failure
to do so may adversely affect the safety and
handling of your car. Furthermore, speeding,
rapid acceleration, sudden brake applications,
and sharp turns are potentially very hazardous
practices.
During deceleration, use engine braking to the
fullest extent. Sudden brake applications on
snowy or icy roads may cause skids to occur.
You need to keep sufficient distance between
the vehicle in operation in front and your vehicle.
Also, apply the brake gently. It should be noted
that installing tire chains on the tire will provide
a greater driving force, but will not prevent side
skids.
NOTE:Tire chains are not legal in all states. Check
state laws before fitting tire chains.
C150A01A-AAT
Avoid braking or gear changing in corners,
especially when roads are wet. Ideally, cor-
ners should always be taken under gentle
acceleration. If you follow these suggestions,
tire wear will be held to a minimum.

C160D01A-AATCheck Battery and Cables
Winter puts additional burdens on the battery
system. Visually inspect the battery and cables
as described in Section 6. The level of charge in
your battery can be checked by your Hyundai
dealer or a service station.
C160E01A-AAT
Change to "Winter Weight" Oil if
Necessary
In some climates it is recommended that a lower
viscosity "winter weight" oil be used during cold
weather. See Section 9 for recommendations. If
you aren't sure what weight oil you should use,
consult your Hyundai dealer.
C160C01A-AAT
Use High Quality Ethylene Glycol
Coolant
Your Hyundai is delivered with high quality eth-
ylene glycol coolant in the cooling system. It is
the only type of coolant that should be used
because it helps prevent corrosion in the cooling
system, lubricates the water pump and prevents
freezing. Be sure to replace or replenish your
coolant in accordance with the maintenance
schedule in Section 5. Before winter, have your
coolant tested to assure that its freezing point is
sufficient for the temperatures anticipated dur-
ing the winter.
C160H01A-AAT
Use Approved Anti-Freeze in Window
Washer System
To keep the water in the window washer system
from freezing, add an approved anti-freeze so-
lution in accordance with instructions on the
container. Window washer anti-freeze is avail-
able from Hyundai dealers and most auto parts
outlets. Do not use engine coolant or other types
of anti-freeze as these may damage the finish.
C160F01A-AAT
Check Spark Plugs and Ignition
System
Inspect your spark plugs as described in Sec-
tion 6 and replace them if necessary. Also
check all ignition wiring and components to be
sure they are not cracked, worn or damaged in
any way.
C160G01A-AAT
To Keep Locks from Freezing
To keep the locks from freezing, squirt an ap-
proved de-icer fluid or glycerine into the key
opening. If a lock is covered with ice, squirt it
with an approved de-icing fluid to remove the
ice. If the lock is frozen internally, you may be
able to thaw it out by using a heated key. Handle
the heated key with care to avoid injury.

HIGHER SPEED MOTORING
C160I01A-AAT
Don't Let Your Parking Brake Freeze
Under some conditions your parking brake can
freeze in the engaged position. This is most
likely to happen when there is an accumulation
of snow or ice around or near the rear brakes or
if the brakes are wet. If you think the parking
brake may freeze, apply it only temporarily while
you put the gear selector lever in "P" (automatic)
or in first or reverse gear (manual transaxle) and
block the rear wheels so the car cannot roll.
Then release the parking brake.
C160K01A-AAT
Carry Emergency Equipment
Depending on the severity of the weather where
you drive your car, you should carry appropriate
emergency equipment. Some of the items you
may want to carry include tire chains, tow straps
or chains, flashlight, emergency flares, sand, a
shovel, jumper cables, a window scraper, gloves,
ground cloth, coveralls, a blanket, etc.
C160J01A-AAT
Don't Let Ice and Snow Accumulate
Underneath
Under some conditions, snow and ice can build
up under the fenders and interfere with the
steering. When driving in severe winter condi-
tions where this may happen, you should peri-
odically check underneath the car to be sure the
movement of the front wheels and the steering
components is not obstructed.
C170A01A-AAT
Pre-Trip Inspections
1. Tires:
Adjust the tire inflation pressures for highway
driving. Low tire inflation pressures will result in
overheating and possible failure of the tires.
Avoid using worn or damaged tires which may
result in reduced traction or tire failure.
NOTE:Never exceed the maximum tire inflation pres-
sure shown on the tires.
2. Fuel, engine coolant and engine oil:
High speed travel consumes more fuel than
urban motoring. Do not forget to check both
engine coolant and engine oil.
3. Drive belt:
A loose or damaged drive belt may result in
overheating of the engine.

!
D010B02A-AAT
If Engine Doesn't Turn Over or Turns
Over Slowly
D010A01A-AATD010C01A-AAT
If Engine Turns Over Normally but Does
Not Start
1. Check fuel level.
2. With the key in the "OFF" position, check all
connectors at ignition coil and spark plugs.
Reconnect any that may be disconnected or
loose.
3. Check the fuel line in the engine room.
4. If the engine still refuses to start, call a
Hyundai dealer or seek other qualified assis-
tance.
WARNING:If the engine will not start, do not push or
pull the car to start it. This could result in a
collision or cause other damage. In addition,
push or pull starting may cause the catalytic
converter to be overloaded and create a fire
hazard.
D010B01AD010C01A-D
1. If your car has an automatic transaxle, be
sure the gear selector lever is in "N" or "P"
and the emergency brake is set.
2. Check the battery connections to be sure
they are clean and tight.
3. Turn on the interior light. If the light dims or
goes out when you operate the starter, the
battery is discharged.
4. Check the starter connections to be sure
they are securely tightened.
5. Do not push or pull the vehicle to start it. See
instructions for "Jump Starting".

WHAT TO DO IN AN EMERGENCY
IF THE ENGINE OVERHEATS
!
!WARNING:While the engine is running, keep hands,
long hair and clothing away from moving
parts such as the fan and drive belts to
prevent injury.
D030A02A-AAT
If 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 conditioner is on,
turn it off.
3. If 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 cool-
ant has stopped running or the steaming has
stopped. If there is no visible loss of 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
conditioner had been in use, it is normal for
cold water to be draining from it when you
stop).5. If the water pump drive belt is broken or
coolant is leaking out, stop the engine im-
mediately and call the nearest Hyundai deal-
er for assistance.
WARNING:Do not remove the radiator cap when the
engine is hot. This may allow coolant to be
blown out of the opening and cause serious
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 water to the reservoir
(Page 6-7) 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 hap-
pens again, call a Hyundai dealer for assis-
tance. Then attach the other end of that cable to a
solid metal part of the engine away from the
battery. Do not connect the cable to any
moving part.
4. Start the engine in the car with the booster
battery and let it run for a few minutes. This
will help to assure that the booster battery is
fully charged. During the jumping operation,
run the engine in this vehicle at about 2000
rpm.
5. Start the engine in the car with the dis-
charged battery using the normal starting
procedure. After the engine starts, leave the
jumper cables connected and let the engine
run at fast idle or about 2000 rpm for several
minutes.
6. Carefully remove the jumper cables in the
reverse order of attachment.
If you do not know why your battery became
discharged (because the lights were left on,
etc.), have the charging system checked by
your Hyundai dealer.

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.

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.

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

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
o Drive Belts
Inspect all drive belts for evidence of cuts,
cracks, excessive wear or oil saturation and
