C050B01A-AATNormal Conditions:
The Starting Procedure:
1. Insert key, and fasten the seat belt.
2. Depress the clutch pedal fully and place the
gearshift lever (manual transaxle) in neutral
or the selector lever (automatic transaxle) in
"P" (park) position.
3. After turning the ignition key to the "ON"
position, make certain all warning lights and
gauges are functioning properly before start-
ing the engine.
WARNING:Be sure that the clutch is fully depressed
when starting a manual transaxle vehicle.
Your manual transaxle equipped vehicle
will not start unless the clutch pedal is fully
depressed. On a manual transaxle equipped
vehicle that can be started without de-
pressing the clutch, there is the potential to
cause
damage to the vehicle or injury to someone
inside or outside the vehicle as a result of
the forward or backward movement of the
vehicle that will occur if the clutch is not
depressed when the vehicle is started.4. Turn the ignition key to the "Start" position
and release it when the engine starts.
After the engine has started, allow the engine
to run for 10 to 20 seconds prior to placing
the vehicle in gear.
The starter should not be operated for more
than 15 seconds at a time. Wait 15-30 sec-
onds between starting attempts to protect
the starter from overheating.

OPERATING THE MANUAL
TRANSAXLE
Your Hyundai's manual transaxle has a con-
ventional shift pattern. This shift pattern is im-
printed on the shift knob. The transaxle is fully
synchronized in all forward gears so shifting to
either a higher or a lower gear is easily accom-
plished.
NOTE:o To shift into reverse, rest the lever in
neutral for at least 3 seconds after your
car is completely stopped. Then move
the lever into the reverse position.
o During cold weather, shifting may be
difficult until the transaxle lubricant has
warmed up. This is normal and not harm-
ful to the transaxle.
o If you've come to a complete stop and
it's hard to shift into 1st or R(Reverse),
put the shift lever in N(Neutral) position
and release the clutch. Press the clutch
pedal back down, and then shift into 1st
or R(Reverse) gear position.
o Do not use the shift lever as a handrest
during driving, as this can result in pre-
mature wear of the transaxle shift forks.
!CAUTION:When downshifting from fifth gear to fourth
gear, caution should be taken not to inad-
vertently press the gear lever sideways in
such a manner that second gear is en-
gaged. Such a drastic downshift may cause
the engine speed to increase to the point
that the tachometer will enter the red-zone.
Such over-revving of the engine may pos-
sibly cause engine damage.

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.

C090E01O-AAT
o D(Drive):
Use for normal driving. The transaxle will auto-
matically shift through a four gear sequence.
C090F02O-GATSports Mode
C090D02O-AATo N (Neutral):
In the "N" position, the transaxle is in neutral,
which means that no gears are engaged. The
engine can be started with the shift lever in "N"
position, although this is not recommended
except if the engine stalls while the car is
moving.
C090B01A-AATThe function of each position is as fol-
lows:
o P (Park):
Use to hold the vehicle in place when parked or
while starting the engine; shift the selector lever
to the "P" (Park) position. Whenever parking the
car, apply the parking brake and shift the selec-
tor lever to the "P" (Park) position.
C090C01A-AATo R(Reverse):
Use for backing up the vehicle. Bring the car to
a complete stop before shifting the selector
lever to "R" position.
CAUTION:Never place the selector lever in the "P"
(Park) position unless the vehicle is fully
stopped. Failure to observe this caution
will cause severe damage to the transaxle.Whether the vehicle is stationary or in motion,
sports mode is selected by pushing the selector
lever from the "D" position into the manual gate.
To return to "D" range operation, push the
selector lever back into the main gate.
In sports mode, moving the selector lever back-
wards and forwards can make rapid gearshifts
simple. In contrast to a manual transaxle, the
sports mode allows gearshifts with the accel-
erator pedal depressed.
UP (+) : Push the lever forward once to shift up
one gear.
DOWN (-) : Pull the lever backwards once to
shift down one gear.
SKIP : By rapidly moving the selector forward or
backward twice, it is possible to skip one gear,
i.e. 1st to 3rd or 3rd to 1st .HXG200
!

DRIVING YOUR HYUNDAI 2- 9
CAUTION:o In sports mode, the driver must execute
upward shifts in accordance with pre-
vailing road conditions, taking care to
keep the engine speed below the red
zone.
o For engine protection, upward shifts are
made automatically when the engine
rpm reaches the red zone.
o By rapidly moving the selector lever back-
wards (-) twice it is possible to skip one
gear, i.e., 3rd to 1st, 4th to 2nd. Since
sudden engine braking and/or rapid ac-
celeration can cause a loss of traction,
however, downshifts must be made care-
fully in accordance with the vehicle's
speed.
!
C090H01L-GATNOTE:o For smooth and safe operation, depress
the brake pedal when shifting from "Neu-
tral" position or "Park" position to a
forward or reverse gear.
o The ignition key must be in the "ON"
position and the brake pedal fully de-
pressed in order to move the shift lever
from the "P" (Park) position to any of the
other positions.
o It is always possible to shift from "R",
"N", "D" position to "P" position. The
vehicle must be fully stopped to avoid
transaxle damage.
C090I02L-GAT
CAUTION:
o Shift into "R" and "P" position only when
the vehicle has completely stopped.
o Do not accelerate the engine in reverse
or any of the forward positions with the
brakes applied.
o Always apply the footbrake when shift-
ing from "P" or "N", to "R", "D"position.
o Do not use the "P" (Park) position in
place of the parking brake. Always set
the parking brake, shift the transaxle
into "P" (Park) position and turn off the
ignition when you leave the vehicle, even
momentarily. Never leave the vehicle
unattended while the engine is running.
o Check the automatic transaxle fluid level
regularly, and add fluid as necessary.
o See the maintenance schedule for the
proper fluid recommendation.
!
NOTE:o In sports mode, only the four forward
gears can be selected. To reverse or park
the vehicle, move the selector lever to
the "R" or "P" position as required.
o In sports mode, downward shifts are
made automatically when the vehicle
slows down. When the vehicle stops, 1st
gear is automatically selected.
o To maintain the required levels of ve-
hicle performance and safety, the sys-
tem may not execute certain gearshifts
when the selector lever is operated.o Before driving away from a stop on a
slippery road, push the selector lever
forward into the +(UP) position. This
causes the transaxle to shift into 2nd
gear which is better for smooth driving
away on a slippery road. Push the selec-
tor lever to the -(DOWN) side to shift
back to 1st gear.

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.
