DRIVING YOUR HYUNDAI

o Remember, your Hyundai does not require
extended warm-up. After the engine has
started, allow the engine to run for 10 to 20
seconds prior to placing the vehicle in gear.
In very cold weather, however, give your
engine a slightly longer warm-up period.
o Don't "lug" or "over-rev" the engine. Lugging
is driving too slowly in too high a gear result-
ing in the engine bucking. If this happens,
shift to a lower gear. Over-revving is racing
the engine beyond its safe limit. This can be
avoided by shifting at the recommended
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. o Be sure that the wheels are aligned cor-
rectly. Improper alignment can result from
hitting curbs or driving too fast over irregular
surfaces. Poor alignment causes faster tire
wear and may also result in other problems
as well as greater fuel consumption.
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
Section 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.
DRIVING FOR ECONOMYC140A02A-AATYou 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 pos-
sible. 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
increase wear on these components. In
addition, 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
inflation, either too much or too little, results
in unnecessary tire wear. Check the tire
pressures at least once a month.

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 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-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 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.
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 instruc-
tions 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 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
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 distrib-
utes 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 re-
quirements.
Since laws vary from State to State the require-
ments 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 consult
your Hyundai dealer for further informa-
tion on additional requirements such as
a towing kit, etc.
USE OF LIGHTSC180A01A-AATCheck your lights regularly for correct opera-
tion 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, especially
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, downshift the
transaxle to a lower gear and reduce speed
to reduce chances of engine overloading
and/or overheating.
CAUTION:
If overheating should occur when towing,
(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.

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.

D080B02NF
CAUTION:
o Automatic Transaxle:
Be sure to use a towing dolly under the front
wheels.
A vehicle with an automatic transaxle should
never be towed from the rear with the front
wheels on the ground. This can cause se-
rious damage to the transaxle.
3) It is recommended that your vehicle be
towed with all the wheels off the ground.
EMERGENCY TOWINGD080D01NF-AAT
!
D080D02NF-A
For emergency towing when no commercial
tow vehicle is available, attach a tow cable,
chain or strap to the towing hook under the front
of your car. Do not attempt to tow your vehicle
in this manner on any unpaved surface. This
could result in serious damage to your car.
Nor should towing be attempted if the wheels,
drive train, axles, steering or brakes are dam-
aged. Before towing, be sure the transaxle is in
neutral and the key is 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.
CAUTION:
If the car is being towed with all four wheels
on the ground, it can be towed only from the
front. Be sure that the transaxle is in neutral.
Do not tow at speeds greater than 30 mph
(50 km/h) and for more than 15 miles (25
km). Be sure the steering is unlocked by
placing the key in the "ACC" position. A
driver must be in the towed vehicle to
operate the steering and brakes.NOTE:Before towing, check the level of the auto-
matic transaxle fluid. If it is below the "HOT"
range on the dipstick, add fluid. If you
cannot add fluid, a towing dolly must be
used.

2. Remove the transaxle dipstick, wipe it clean,
reinsert the dipstick as far as it will go, then
remove it again. Now check the fluid level on
the dipstick. It should be in the "HOT" range
on the dipstick.
G110D02O-AATTo Check the Transaxle Fluid LevelPark the car on level ground with the parking
brake engaged. When the transaxle fluid level
is checked, the transaxle fluid should be at
normal operating temperature and the engine
idling.
While the engine is idling, apply the brakes and
move the gear selector lever from "P" to each
of its other positions — "R", "N", "D" — and then
return to "N" or "P". With the engine still idling:
1. Open the hood, being careful to keep hands,
long hair and clothing clear of any moving
parts.
G110D01NF
C090F02NF
G110D02NF
Fluid level should be within "HOT" range
3. If the transaxle fluid level is low, use a funnel
to add transaxle fluid through the dipstick
tube until the level reaches the "HOT" range.
Do not overfill.

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 imme-
diately.
!
WARNING:
The cooling fan is controlled by engine
coolant temperature and may sometimes
operate even when the engine is not run-
ning. 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 de-
creases, 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 mainte-
nance 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.
