C160J01A-AATDon't Let Ice and Snow Accumulate
UnderneathUnder some conditions, snow and ice can
build up under the fenders and interfere
with the steering. When driving in severe
winter conditions where this may happen,
you should periodically check underneath
the car to be sure the movement of the front
wheels and the steering components is
not obstructed.C160I01A-AATDon't Let Your Parking Brake FreezeUnder 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 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.
C160H02A-AATUse Approved Window Washer Anti-
Freeze in SystemTo keep the water in the window washer
system from freezing, add an approved
window washer anti-freeze solution in
accordance with instructions on the
container. Window washer anti-freeze is
available from Hyundai dealers and most
auto parts outlets. Do not use engine coolant
or other types of anti-freeze as these may
damage the paint finish.C160G01A-AATTo Keep Locks from FreezingTo 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 injury.
C160F01A-AATCheck Spark Plugs and Ignition
SystemInspect your spark plugs as described in
Section 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
NecessaryIn 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.

C190B01S-AATTrailer HitchesSelect the proper hitch and ball
combination, making sure that its location
is compatible with that of the trailer or
vehicle being towed.
Use a quality non-equalizing hitch which
distributes the tongue load uniformly
throughout the chassis.
The hitch should be bolted securely to the
car and installed by a qualified technician.
DO NOT USE A HITCH DESIGNED FOR
TEMPORARY INSTALLATION AND
NEVER USE ONE THAT ATTACHES
ONLY TO THE BUMPER.C190C01Y-AATTrailer BrakesIf your trailer is equipped with a braking
system, make sure it conforms to federal
and/or local regulations and that it is
properly installed and operating correctly.NOTE:If you tow a trailer or vehicle, your car will
require more frequent maintenance due
to the additional load. See Maintenance
Under Severe Usage Conditions" on
page 5-6.
TRAILER OR VEHICLE TOWING!
C190A01TG-AATIf you are considering towing with your car,
you should first check with your State's
Department of Motor Vehicles to determine
their legal requirements.
Since laws vary from State to State the
requirements for towing trailers, cars, or
other types of vehicles or apparatus may
differ. Ask your Hyundai dealer for further
details before towing.
CAUTION:
o Do not do any towing with your car
during its first 1,200 miles (2,000 km)
in order to allow the engine to properly
break in. Failure to heed this caution
may result in serious engine or
transaxle damage.
o When towing a trailer, be sure to con-
sult your Hyundai dealer for further
information on additional require-
ments such as a towing kit, etc.
USE OF LIGHTSC180A01A-AATCheck your lights regularly for correct op-
eration and always keep them clean. When
driving during the day in conditions of poor
visibility, it is helpful to drive with headlights
on low beam. This enables you to be seen,
as well as to see.

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.

WHAT TO DO IN AN EMERGENCY
CHANGING A FLAT TIRE
IF YOU HAVE A FLAT TIRE
D060A01A-AATThe procedure described on the follow-
ing pages can be used to rotate tires as
well as to change a flat tire. When
preparing to change a flat tire, check to
be sure the gear selector lever is in "P"
(automatic transaxle) or reverse gear
(manual transaxle) and that the parking
brake is set, then:
D050A01A-AATIf a tire goes flat while you are driving:
1. Take your foot off the accelerator pedal
and let the car slow down while driving
straight ahead. Do not apply the brakes
immediately or attempt to pull off the
road as this may cause a loss of
control. When the car has slowed to
such a speed that it is safe to do so,
brake carefully and pull off the road.
Drive off the road as far as possible
and park on firm, level ground. If you
are on a divided highway, do not park
in the median area between the two
traffic lanes.
2. When the car is stopped, turn on your
emergency hazard flashers, set the
parking brake and put the transaxle in
"P" (automatic) or reverse (manual
transaxle).
3. Have all passengers get out of the car.
Be sure they all get out on the side of
the car that is away from traffic.
4. Change the tire according to the in-
structions provided as follows.
D060A01NF-A
D040B01NF-GATHandling the Spare Tire
To remove the spare tire, take out the
tool receptacle and remove the installa-
tion bolt by turning it counterclockwise.
After replacing the spare tire, install and
tighten the bolt firmly with your fingers
until there is no more play in the spare
tire.

CHECKING THE BRAKES!
G120B01A-AATChecking the Brake Fluid Level
WARNING:Use caution when handling brake fluid. It
can damage your vision if it gets into
your eyes. It will also damage your
vehicle's paint if spilled on it and not
removed immediately.
!
WARNING:
The cooling fan is controlled by engine
coolant temperature and may
sometimes operate even when the
engine is not running. Use extreme
caution when working near the blades of
the cooling fan so that you are not injured
by a rotating fan blade. As the engine
coolant temperature decreases, the fan
will automatically shut off. This is a
normal condition.
G120A01A-AAT
CAUTION:
Because brakes are essential to the
safe operation of the car, it is suggested
that they be checked and inspected by
your Hyundai dealer. The brakes should
be checked and inspected for wear at
those intervals specified in the vehicle
maintenance schedule in Section 5.
!
G120D01A-AATTo Check the Fluid LevelThe fluid level in the brake fluid reservoir
should be checked periodically. The level
should be between the "MIN" and "MAX"
marks on the side of the reservoir. If the
level is at or below the "MIN" mark, carefully
add fluid to bring it up to "MAX". Do not
overfill.G120C02A-AATRecommended Brake FluidUse only hydraulic brake fluid conforming
to DOT 3 or DOT 4 specifications in your
braking system. Follow the instructions
printed on the container.
