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.
C070A02A-AAT
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.

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.

car while the jack is being used.
D060G02Y-AAT6. Changing Wheels
D060H02A-AAT7. Reinstall Wheel Nuts
Loosen the wheel nuts and remove them with
your fingers. Slide the wheel off the studs and
lay it flat so it cannot roll away. To put the wheel
on the hub, pick up the spare tire, line up the
holes with the studs and slide the wheel onto
them. If this is difficult, tip the wheel slightly and
get the top hole in the wheel lined up with the top
stud. Then jiggle the wheel back and forth until
the wheel can be slid over the other studs.
WARNING:Wheels and wheel covers may have sharp
edges. Handle them carefully to avoid pos-
sible severe injury. Before putting the wheel
into place, be sure that there is nothing on
the hub or wheel (such as mud, tar, gravel,
etc.) that interferes with the wheel from
fitting solidly against the hub. If there is,
remove it. If there is not good contact on the
mounting surface between the wheel and
hub, the wheel nuts could come loose and
cause the loss of a wheel. Loss of a wheel
may result in loss of control of the vehicle.
This may cause serious injury or death.To reinstall the wheel, hold it on the studs, put
the wheel nuts on the studs and tighten them
finger tight. The nuts should be installed with
their small diameter ends directed inward. Jiggle
the tire to be sure it is completely seated, then
tighten the nuts as much as possible with your
fingers again.

DO-IT-YOURSELF MAINTENANCE 6- 19
!
If any of your car’s lights or other electrical
accessories stop working, a blown (open) fuse
could be the reason. If the fuse has opened, you
will see that the metal strip inside the fuse has
melted through. If you suspect a blown fuse,
follow this procedure:
1. Turn off the ignition and all other switches.
2. Open the instrument panel junction box and
examine each fuse. Remove each fuse by
pulling it toward you (a small "fuse puller" tool
is contained in the fuse box to simplify this
operation).
3. Be sure to check all other fuses even if you
find one that appears to have burned out.
4. Replace the blown fuse by pressing a new
fuse of the same rating into place. The fuse
should be a snug fit. If it is not, have the fuse
clip repaired or replaced by a Hyundai dealer.

G210A01A-AATCHECKING THE BATTERY
WARNING:
Batteries can be dangerous! When working
with batteries, carefully observe the follow-
ing precautions to avoid serious injuries.
The fluid in the battery contains a strong solution
of sulfuric acid, which is poisonous and highly
corrosive. Be careful not to spill it on yourself or
the car. If you do spill battery fluid on yourself,
immediately do the following:
o If battery fluid is on your skin, flush the
affected areas with water for at least 15
minutes and then seek medical assistance.
o If battery fluid is in your eyes, rinse out your
eyes with water and get medical assistance
as soon as possible. While you are being
driven to get medical assistance, continue to
rinse your eyes by using a sponge or soft
cloth saturated with water.
o If you swallow battery fluid, drink a large
quantity of water or milk followed by milk of
magnesia, eat a raw egg or drink vegetable
oil. Get medical assistance as soon as
possible. If you do not have a spare fuse, you may be
able to borrow a fuse of the same or lower
rating from an accessory you can tempo-
rarily get along without (the radio or cigarette
lighter, for example). Always remember to
replace the borrowed fuse.
CAUTION:A burned-out fuse indicates that there is a
problem in the electrical circuit. If you re-
place a fuse and it blows as soon as the
accessory is turned on, the problem is
serious and should be referred to a Hyundai
dealer for diagnosis and repair. Never re-
place a fuse with anything except a fuse
with the same or a lower amperage rating.
A higher capacity fuse could cause damage
and create a fire hazard.
NOTE:See page 6-29 for the junction box descrip-
tions.
