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.

CORROSION PREVENTION AND APPEARANCE CARE 4- 5
Take a piece of cheese cloth and using any mild
soap and lukewarm water, work up a good
lather. Thoroughly wash the leather. Wipe clean
with a slightly damp cloth and dry with soft cloth.
Do this as often as the leather becomes
soiled.
During tanning operations, sufficient oils are
incorporated through processing that none need
be applied during the life of the leather. Oil
applied to the finished surface will in no way help
the leather and may do more harm than good.
Varnishes and furniture polishes should never
be used under any conditions.E040D01A-AATCleaning the Seat Belts
To clean the seat belts, use a cloth or sponge
with mild soap or detergent and warm water. Do
not use strong detergents, dye, bleach or abra-
sive materials on the seat belts as this may
weaken the fabric.
While cleaning the belts, inspect them for ex-
cessive wear, cuts, fraying or other signs of
damage and replace them if necessary.
E040C01A-AATCleaning the Carpets
Use a foam-type carpet cleaner. Cleaners of
this type are available in aerosol cans in liquid
form or powder. Read the instructions and
follow them exactly. Using a vacuum cleaner
with the appropriate attachment, remove as
much dirt from the carpets as possible. Apply
the foam following the manufacturer's direc-
tions, then rub in overlapping circles. Do not add
water. These cleaners work best when the
carpet is kept as dry as possible.
E050A01A-AATAny Questions?
If you have any questions about the care of your
car, consult your Hyundai dealer.
E040E01A-AATCleaning the Windows
You may use any household window cleaner on
the windows. However, when cleaning the in-
side of the rear window be careful not to damage
the rear window defroster wiring.

DO-IT-YOURSELF MAINTENANCE 6- 21
G250A01A-AATFOR MORE INFORMATION ABOUT
YOUR HYUNDAI
If you desire additional information about main-
taining and servicing your Hyundai, you may
purchase a factory Shop Manual at your Hyundai
dealer's parts department. This is the same
manual used by dealership technicians and
while it is highly technical it can be useful in
obtaining a better understanding of your car and
how it works.
G240A01A-AATPOWER STEERING HOSES
It is suggested that you check the power steer-
ing hose connections for fluid leakage at regular
intervals. The power steering hoses should be
replaced if there is severe surface cracking,
scuffing or worn spots. Deterioration of the hose
could cause premature failure. Recommended Fluid
Use PSF-3 type fluid
NOTE:Do not start the engine when the power
steering oil reservoir is empty.
G260A02A-AATREPLACING HEADLIGHT BULBS
Before attempting to replace a headlight bulb, be
sure the switch is turned to the "OFF" position.
The next paragraph shows how to reach head-
light bulbs so they may be changed. Be sure to
replace the burned-out bulb with one of the
same number and wattage rating.
!CAUTION:Keep the lamps out of contact with petro-
leum products such as oil, gasoline etc.
