FEATURES OF YOUR HYUNDAI 1- 35
B260B01A-AATSRS (Airbag) Service
Reminder Indicator (SRI)
The SRS service reminder indicator (SRI) comes
on and flashes for about 6 seconds after the
ignition key is turned to the "ON" position or after
the engine is started, after which it will go out.
This light also comes on when the SRS is not
working properly. If the SRI does not come on,
or continuously remains on after flashing for
about 6 seconds when you turned the ignition
key to the "ON" position or started the engine,
or if it comes on while driving, have the SRS
inspected by an authorized Hyundai Dealer.
B260D01A-AATTurn signal Indicator Lights
The blinking green arrows on the instrument
panel show the direction indicated by the turn
signals. If the arrow comes on but does not blink,
blinks more rapidly than normal, or does not
illuminate at all, a malfunction in the turn signal
system is indicated. Your dealer should be
consulted for repairs.
B260E01L-AATSeat Belt Reminder Light
And Chime
Seat belt reminder light comes and stays on until
the seat belt is fastened when the ignition key is
turned "ON" or "START".
And, the warning chime will also sound for about
6 seconds.
B260F01A-AATHigh Beam Indicator Light
The high beam indicator light comes on when-
ever the headlights are switched to the high
beam or flash position.
B260G01A-AATOil Pressure Warning Light
CAUTION:
If the oil pressure warning light stays on
while the engine is running, serious engine
damage may result. The oil pressure warn-
ing light comes on whenever there is insuf-
ficient oil pressure. In normal operation, it
should come on when the ignition switch
is turned on, then go out when the engine
is started. If the oil pressure warning light
stays on while the engine is running, there
is a serious malfunction.
If this happens, stop the car as soon as it is
safe to do so, turn off the engine and check
the oil level. If the oil level is low, fill the
engine oil to the proper level and start the
engine again. If the light stays on with the
engine running, turn the engine off imme-
diately. In any instance where the oil light
stays on when the engine is running, the
engine should be checked by a Hyundai
dealer before the car is driven again.

2- 2 DRIVING YOUR HYUNDAI
WARNING: ENGINE EXHAUST CAN BE DANGEROUS!C010A02A-AATEngine exhaust fumes can be extremely dangerous. If, at any time, you smell exhaust fumes inside the vehicle, open the windows
immediately.
Engine exhaust, some of its constituents, and certain vehicle components contain or emit chemicals known to the
State of California to cause cancer and birth defects and reproductive harm. In addition, certain fluids contained in
vehicles and certain products of component wear contain or emit chemicals known to the State of California to cause
cancer and birth defects or other reproductive harm.
o Do not inhale exhaust fumes.
Exhaust fumes contain carbon monoxide, a colorless, odorless gas that can cause unconsciousness and death by asphyxiation.
o Be sure the exhaust system does not leak.The exhaust system should be checked whenever the vehicle is raised to change the oil or for any other purpose. If you hear
a change in the sound of the exhaust or if you drive over something that strikes the underneath side of the car, have the exhaust
system checked as soon as possible by your Hyundai dealer.
o Do not run the engine in an enclosed area.Letting the engine idle in your garage, even with the garage door open, is a hazardous practice. Never run the engine in your
garage any longer than it takes to start the engine and back the car out.
o Avoid idling the engine for prolonged periods with people inside the car.
If it is necessary to idle the engine for a prolonged period with people inside the car, be sure to do so only in an open area with
the air intake set at "Fresh" and fan operating at one of the higher speeds so fresh air is drawn into the interior.
If you must drive with the trunk open because you are carrying objects that make this necessary:
1. Close all windows.
2. Open side vents.
3. Set the air intake control at "Fresh", the air flow control at "Floor" or "Face" and the fan at one of the higher speeds.
To assure proper operation of the ventilation system, be sure the ventilation air intakes located just in front of the windshield are
kept clear of snow, ice, leaves or other obstructions.

2- 14 DRIVING YOUR HYUNDAI
C160G01A-AATTo Keep Locks from Freezing
To keep the locks from freezing, squirt an
approved 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 burning the
fingers.
C160D01A-AAT
Check 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.
C160F01A-AATCheck 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.
C160E01A-AATChange 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-AATUse High Quality Ethylene Glycol
Coolant
Your Hyundai is delivered with high quality
ethylene glycol coolant in the cooling system. It
is the only type of coolant that should be used
because it helps prevent corrosion in the cool-
ing system, lubricates the water pump and
prevents freezing. Be sure to replace or replen-
ish your coolant in accordance with the main-
tenance schedule in Section 5. Before winter,
have your coolant tested to assure that its
freezing point is sufficient for the temperatures
anticipated during the winter.
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 of 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.

DRIVING YOUR HYUNDAI 2- 15
C160J01A-AATDon'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.
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 there is a risk the
parking brake may freeze, apply it only tempo-
rarily 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.
C160H01A-AATUse Approved Anti-Freeze in Window
Washer System
To keep the water in the window washer system
from freezing, add an approved anti-freeze
solution 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.
C160K01A-AAT
Carry Emergency Equipment
Depending on the severity of the weather where
you drive your car, you should carry appropri-
ate 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.
C170A01A-AATHIGHER SPEED MOTORING
Pre-Trip Inspections
1. Tires:
Adjust the tire inflation pressures to specifica-
tion. 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
pressure shown on the tires.
2. Fuel, engine coolant and engine oil:
High speed travel consumes 1.5 times 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.

5- 2 VEHICLE MAINTENANCE REQUIREMENTS
F010D01A-AATGeneral 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 6-4.
F010C01A-AATSpecified 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 trained technicians at your
Hyundai dealer, these procedures may be per-
formed 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 Hand-
book provides further information about your
warranty coverage.
F010A01A-AATMAINTENANCE INTERVALS
Service Requirements
To ensure that you receive the greatest number
of miles of satisfying operation from your Hyundai,
certain maintenance procedures must be per-
formed. Although careful design and engineer-
ing have reduced these to a minimum, those that
are required are of the utmost importance.
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.
F010B01A-AATMaintenance 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
F010E01A-AATDo-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.
F010F01A-AATA Few Tips
o Whenever you have your Hyundai serviced,
keep copies of the service records in your
glovebox. 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.
