C090A03Y-AATAUTOMATIC TRANSAXLE
The highly efficient Hyundai automatic transaxle
has four forward speed and one reverse speed.
The individual speeds are selected automati-
cally, depending on the position of the speed
selector lever. The selector lever has 2 gates;
the main gate and the manual gate.
NOTE:For information on manual gate operation,
refer to "Sports Mode".
In the main gate, the selector lever has 4
positions, and is equipped with a button to avoid
inadvertent wrong selection.
NOTE:Depress the brake pedal and push
the button when shifting.
Push the button when shifting.
The selector lever can be shifted
freely.
The first few shifts on a new vehicle, or if the
battery has been disconnected, may be
somewhat abrupt. This is a normal condi-
tion, and the shifting sequence will adjust
after shifts are cycled a few times by the
T.C.M (Transaxle Control Module).
CAUTION:Never shift into "R" or "P" position while the
vehicle is moving.
!
The indicator lights in the instrument cluster
indicate the selector lever position when the
ignition is switched "ON". During the sports
mode operation, the gear currently in use dis-
plays in the numeral indicator.C090A01YC090A02L

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.
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.

DRIVING YOUR HYUNDAI 2- 11
!
o Driving on rough, gravel or snow-cov-
ered roads.
o Driving with tire chains installed.
o Driving on roads where the road surface
is pitted or has different surface height.
During these conditions the vehicle should
be driven at reduced speeds. The safety
features of an ABS equipped vehicle should
not be tested by high speed driving or
cornering. This could endanger the safety
of yourself or others.
C300A03Y-GAT
TRACTION CONTROL SYSTEM (TCS)
(If installed)
!
C300B01E-GATTCS ON/OFF Mode
In the TCS ON mode, the indicator in the
instrument cluster will not be illuminated.
To switch the TCS OFF mode, press the TCS
switch . And the SLIP control will be deactivated
and the TCS indicator in the instrument cluster
will be illuminated.
NOTE:1) Turn off the engine. Then restart the
engine, and the TCS mode will automati-
cally turn "ON".
2) When the traction control is operating
properly, you can feel a slight pulsation
in the vehicle. This is only the effect of
brake control and indicates nothing
unusual.
3) When the engine starts, a click is heard
from the engine compartment; however,
this is only the sound of traction control
being checked.
4) When moving out of the mud or fresh
snow, pressing the accelerator pedal
may not cause the engine speed to in-
crease. On slippery road surfaces, the traction control
system (TCS) limits the drive wheels from
spinning excessively, thus helping the car to
accelerate. It also provides sufficient driving
force and steering performance as the car turns
at accelerated speeds. TCS has - SLIP control.
SLIP Control
Limits the drive wheels from spinning exces-
sively during starting or while making acceler-
ated turns on slippery roads to avoid losing the
driving force of the front wheels.
Driving hints
TCS does not actively apply brakes. Be sure to
decelerate the car sufficiently before entering
curves.
CAUTION:When the TCS indicator blinks, SLIP control
has been activated. It also means that the
road is slippery or your car is accelerating
excessively. In this situation, release foot
pressure from the accelerator pedal and
maintain moderate speed.
WARNING:Traction control is only a driving aid; all
normal precautions for driving in inclement
weather and on slippery road surfaces
should be observed.

C130A01A-AATGOOD BRAKING PRACTICES
WARNING:
Nothing should be carried on top of the
cargo area cover behind the rear seat. If
there were an accident or a sudden stop,
such objects could move forward and cause
damage to the vehicle or injure the occu-
pants.
o After being parked, check to be sure the
parking brake is not engaged and that the
parking brake indicator light is out before
driving away.
o Driving through water may get the brakes
wet. They can also get wet when the car is
washed. Wet brakes can be dangerous!
Your car will not stop as quickly if the brakes
are wet. Wet brakes may cause the car to
pull to one side. To dry the brakes, apply the
brakes lightly until the braking action returns
to normal, taking care to keep the car under
control at all times. If the braking action does
not return to normal, stop as soon as it is safe
to do so and call your Hyundai dealer for
assistance.
o Don't coast down hills with the car out of gear.
This is extremely hazardous. Keep the car
in gear at all times, use the brakes to slow
down, then shift to a lower gear so that engine
braking will help you maintain a safe speed.o Don't "ride" the brake pedal. Resting your
foot on the brake pedal while driving can be
dangerous because it can result in the brakes
overheating and losing their effectiveness. It
also increases the wear of the brake com-
ponents.
o If a tire goes flat while you are driving, apply
the brakes gently and keep the car pointed
straight ahead while you slow down. When
you are moving slowly enough for it to be safe
to do so, pull off the road and stop in a safe
place.
o If your car is equipped with an automatic
transaxle, don't let your car creep forward.
To avoid creeping forward, keep your foot on
the brake pedal when the car is stopped.
o Use caution when parking on a hill. Engage
the parking brake and place the gear selec-
tor lever in "P" (automatic transaxle) or in first
or reverse gear (manual transaxle). If your
car is facing downhill, turn the front wheels
into the curb to help keep the car from rolling.
If your car is facing uphill, turn the front
wheels away from the curb to help keep the
car from rolling. If there is no curb or if it is
required by other conditions to keep the car
from rolling, block the wheels.
o Under some conditions your parking brake
can freeze in the engaged position. This is
most likely to happen when there is an ac-
cumulation of snow or ice around or near the
rear brakes or if the brakes are wet. If there
is a risk that the parking brake may freeze,
apply it only temporarily while you put the
gear selector lever in "P" (automatic) or in
C300D02L-GATIndicator and Warning
The indicator should illuminate when the ignition
key is turned to "ON" or "start", but should go
out after three seconds.
If the indicator does not illuminate, have it checked
by an authorized Hyundai dealer.
Should there be any unusual conditions in the
device, TCS illuminates as a warning.
If TCS illuminates, pull your car to a safe place
and stop the engine.
Then, start the engine again to check if the TCS
indicator goes out.
If the indicator remains lit even after the engine
has been started, have your car checked by an
authorized Hyundai dealer.
NOTE:1) When TCS illuminates, traction control
is automatically deactivated for safety.
2) This warning function is not provided
when the driver selects the TCS-OFF
mode.

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.

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.

C190D01S-AAT
Safety Chains
Should the hitch connection between your car
and the trailer or vehicle you are towing fail, the
trailer or vehicle could wander dangerously
across other lanes of traffic and ultimately leave
the roadway. To eliminate this potentially dan-
gerous situation, safety chains, attached be-
tween your car and the trailer or towed vehicle,
are required in most states.
CAUTION:o Never connect a trailer brake system
directly to the vehicle brake system.
o When towing a trailer on steep grades (in
excess of 12%) pay close attention to the
engine coolant temperature gauge to
ensure the engine does not overheat. If
the needle of the coolant temperature
gauge moves across the dial towards
"H" (HOT), pull over and stop as soon as
it is safe to do so, and allow the engine
to idle until it cools down. You may
proceed once the engine has cooled
sufficiently.
!
C180A01A-AATUSE OF LIGHTS
Check 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.
C190A01S-AAT
TRAILER OR VEHICLE TOWING
If 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.
C190B01S-AATTrailer Hitches
Select 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.
CAUTION: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. Fail-
ure to heed this caution may result in seri-
ous engine or transaxle damage.
!
C190C01Y-AATTrailer Brakes
If 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.

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.
