WARNING:o Unlocked doors can be dangerous. Be-
fore you drive away (especially if there
are children in the car), be sure that all the
doors are securely closed and locked so
that the doors cannot be opened from
the inside. This helps assure that doors
will not be opened accidentally. Also,
when combined with the proper use of
seat belts, locking the doors helps keep
occupants from being ejected from the
car in case of an accident.
o Before opening the door, always look for
and avoid oncoming traffic.

shift into reverse, depress the clutch, move
the shift lever to neutral, wait three seconds,
then shift to the reverse position.
o Exercise extreme caution when driving on a
slippery surface. Be especially careful when
braking, accelerating or shifting gears. On a
slippery surface, an abrupt change in ve-
hicle speed can cause the drive wheels to
lose traction and the vehicle to go out of
control.C070E02A-AATRecommended Shift Points

C070B01A-AATUsing the Clutch
The clutch should be pressed all the way to the
floor before shifting, then released slowly. The
clutch pedal should always be used after fully
returning to the original position. Do not rest your
foot on the clutch pedal while driving. This can
cause unnecessary wear.
Do not partially engage the clutch to hold the car
on an incline. This causes unnecessary wear.
Use the parking brake to hold the car on an
incline. Do not operate the clutch pedal rapidly
and repeatedly.
C070D02A-AATGood Driving Practices
o Never take the car out of gear and coast
down a hill. This is extremely hazardous.
Always leave the car in gear.
o Don't "ride" the brakes. This can cause them
to overheat and malfunction. Instead, when
you are driving down a long hill, slow down
and shift to a lower gear. When you do this,
engine braking will help slow the car.
o Slow down before shifting to a lower gear.
This will help avoid over-revving the engine,
which can cause damage.
o Slow down when you encounter cross winds.
This gives you much better control of your
car.
o Be sure the car is completely stopped before
you attempt to shift into reverse. The
transaxle can be damaged if you do not. To
WARNING:o Avoid high cornering speeds.
o Do not make quick steering wheel move-
ments, such as sharp lane changes or
fast, sharp turns.
o Always wear your seat belts.
In a collision crash, un unbelted person
is significantly more likely to die than a
person wearing a seatbelt.
o The risk of rollover is greatly increased if
you lose control of your vehicle at high-
way speeds.
o Loss of control often occurs if two or
more wheels drop off the roadway and
the driver oversteers to reenter the road-
way.
o In the event your vehicle leaves the road-
way, do not steer sharply. Instead, slow
down before pulling back into the travel
lanes.
o Never exceed posted speed limits.

C120A02A-AATANTI-LOCK BRAKE SYSTEM
(If installed)
The Anti-Lock Brake System (ABS) is designed
to prevent wheel lock-up during sudden braking
or on hazardous road surfaces. The ABS con-
trol module monitors the wheel speed and con-
trols the pressure applied to each brake. Thus,
in emergency situations or on slick roads, ABS
will increase vehicle control during braking.
NOTE:During ABS operation, a slight pulsation
may be felt in the brake pedal when the
brakes are applied. Also, a noise may be
heard in the engine compartment while
braking. These conditions are normal and
indicate that the anti-lock brake system is
functioning properly.
C090N01O-AATGood Driving Practices
o Never move the gear selector lever from "P"
or "N" to any other position with the accelera-
tor pedal depressed.
o Never move the gear selector lever into "P"
when the vehicle is in motion.
o Be sure the car is completely stopped before
you attempt to shift into "R".
o Never take the car out of gear and coast
down a hill. This may be extremely hazard-
ous. Always leave the car in gear when
moving.
o Do not "ride" the brakes. This can cause
them to overheat and malfunction. Instead,
when you are driving down a long hill, slow
down and shift to a lower gear. When you do
this, engine braking will help slow the car.
o Slow down before shifting to a lower gear.
Otherwise, the lower gear may not be en-
gaged.
o Always use the parking brake. Do not de-
pend on placing the transaxle in "P" to keep
the car from moving.
o Exercise extreme caution when driving on a
slippery surface. Be especially careful when
braking, accelerating or shifting gears. On a
slippery surface, an abrupt change in ve-
hicle speed can cause the drive wheels to
lose traction and the vehicle to go out of
control.
WARNING:ABS will not prevent accidents due to im-
proper or dangerous driving maneuvers.
Even though vehicle control is improved
during emergency braking, always main-
tain a safe distance between you and ob-
jects ahead. Vehicle speeds should always
be reduced during extreme road condi-
tions.
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.
WARNING:o Avoid high cornering speeds.
o Do not make quick steering wheel move-
ments, such as sharp lane changes or
fast, sharp turns.
o Always wear your seat belts.
In a collision crash, un unbelted person
is significantly more likely to die than a
person wearing a seatbelt.
o The risk of rollover is greatly increased if
you lose control of your vehicle at high-
way speeds.
o Loss of control often occurs if two or
more wheels drop off the roadway and
the driver oversteers to reenter the road-
way.

way, do not steer sharply. Instead, slow
down before pulling back into the travel
lanes.
o Never exceed posted speed limits.

first or reverse gear (manual transaxle) and
block the rear wheels so the car cannot roll.
Then release the parking brake.
o Do not hold the vehicle on the upgrade with
the accelerator pedal. This can cause the
transaxle to overheat. Always use the brake
pedal or parking brake.
C140A01A-AATDRIVING FOR ECONOMY
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 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.
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.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. 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.
C160A01A-AATWINTER DRIVING
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:
C150A01A-AAT
SMOOTH CORNERING
Avoid braking or gear changing in corners,
especially when roads are wet. Ideally, corners
should always be taken under gentle accelera-
tion. If you follow these suggestions, tire wear
will be held to a minimum.

2- 18 DRIVING YOUR HYUNDAI
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.
!
C190F01S-AATTrailer or Vehicle Towing Tips
1. Before towing, check hitch and safety chain
connections as well as proper operation of
the trailer running lights, brake lights, and
turn signals.
2. Always drive your vehicle at a moderate
speed (Less than 60 mph)
3. Trailer towing requires more fuel than normal
conditions.
4. To maintain engine braking efficiency and
electrical charging performance, do not use
fifth gear (manual transaxle) or overdrive
(automatic transaxle).
5. Always secure items in the trailer to prevent
load shift while driving.
6. Check the condition and air pressure of all
tires on the trailer and your car. Low tire
pressure can seriously affect the handling.
Also check the spare tire.
7. The vehicle/trailer combination is more af-
fected by crosswind and buffeting.
When being passed by a large vehicle, keep
a constant speed and steer straight ahead.
If there is too much wind buffeting slow down
to get out of the other vehicle's air turbulence.
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.
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 overheat. Use the parking brake
or footbrake.
NOTE:When towing check transaxle fluid more
frequently.
