Manual transaxle operationThe manual transaxle has 6 forward
gears.
This shift pattern is imprinted 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.
To shift gears, press the clutch pedal
down fully, select the desired gear with
the gearshift lever, and release the clutch
pedal slowly.
If your vehicle is equipped with an igni-
tion lock switch, the engine will not start
when starting the engine without
depressing the clutch pedal.
The shift lever must be returned to the
neutral position before shifting into R
(Reverse). The ring (1) located below the
shift knob must be pulled upward while
moving the shift lever to the R (Reverse)
position.Make sure the vehicle is completelystopped before shifting into R (Reverse).
Never operate the engine with thetachometer (rpm) in the red zone.
MANUAL TRANSAXLE (IF EQUIPPED)
OYF059005
The shift lever can be moved into any of
the forward gears without pulling the
ring (1).The ring (1) must be pulled while mov-
ing the shift lever into reverse.
CAUTION
 When downshifting from fifth gear to fourth gear, cautionshould be taken not to inadver- tently press the shift lever side-ways in such a manner that thesecond gear is engaged. Such a drastic downshift may cause theengine speed to increase to the point that the tachometer willenter the red-zone. Such over-revving of the engine and transaxle may possibly causeengine damage.
 Do not downshift more than 2 gears or downshift the gear whenthe engine is running at highspeed (5,000 RPM or higher). Such a downshifting may damagethe engine.

WARNING
 To prevent unintentional move-
ment when stopped and leaving
the vehicle, do not use the
gearshift lever in place of the
parking brake. Set the parking
brake AND make sure the
gearshift lever is securely posi-
tioned in 1st (First) gear or R
(Reverse) for manual transaxle
equipped vehicles and in P (Park)
for automatic transaxle equipped
vehicles.
 Never allow anyone who is unfa- miliar with the vehicle to touch
the parking brake. If the parking
brake is released unintentionally,
serious injury may occur.
 All vehicles should always have the parking brake fully engaged
when parking to avoid inadver-
tent movement of the vehicle
which can injure occupants or
pedestrians.If the parking brake does not release or
does not release all the way, have the
system checked by an authorized
HYUNDAI dealer.
Check the brake warning light by turning
the ignition switch ON (do not start the
engine). This light will be illuminated when
the parking brake is applied with the igni-
tion switch in the START or ON position.
Before driving, be sure the parking brake
is fully released and the brake warning
light is off.
If the brake warning light remains on after
the parking brake is released while the
engine is running, there may be a mal-
function in the brake system. Immediate
attention is necessary.
If at all possible, cease driving the vehi-
cle immediately. If that is not possible,
use extreme caution while operating the
vehicle and only continue to drive the
vehicle until you can reach a safe loca-
tion or repair shop.
Anti-lock brake system (ABS)
W-75
WARNING
ABS (or ESC) will not prevent acci-
dents due to improper or danger-
ous driving maneuvers. Even
though vehicle control is improved
during emergency braking, always
maintain a safe distance between
you and objects ahead. Vehicle
speeds should always be reduced
during extreme road conditions.
The braking distance for cars
equipped with an anti-lock braking
system (or Electronic Stability
Control system) may be longer than
for those without it in the following
road conditions.
During these conditions the vehicle
should be driven at reduced
speeds:
 Rough, gravel or snow-coveredroads.
 With tire chains installed. (Continued)

525
Driving your vehicle
The ABS continuously senses the speed
of the wheels. If the wheels are going to
lock, the ABS system repeatedly modu-
lates the hydraulic brake pressure to the
wheels.
When you apply your brakes under con-
ditions which may lock the wheels, you
may hear a “tik-tik’’ sound from the
brakes, or feel a corresponding sensation
in the brake pedal. This is normal and it
means your ABS is active.
In order to obtain the maximum benefit
from your ABS in an emergency situa-
tion, do not attempt to modulate your
brake pressure and do not try to pump
your brakes. Press your brake pedal as
hard as possible or as hard as the situa-
tion warrants and allow the ABS to con-
trol the force being delivered to the
brakes.
✽ ✽NOTICEA click sound may be heard in the
engine compartment when the vehicle
begins to move after the engine is start-
ed. These conditions are normal and
indicate that the anti-lock brake system
is functioning properly. Even with the anti-lock brake system,
your vehicle still requires sufficient
stopping distance. Always maintain a
safe distance from the vehicle in front
of you.
 Always slow down when cornering. The anti-lock brake system cannot pre-
vent accidents resulting from exces-
sive speeds.
 On loose or uneven road surfaces, operation of the anti-lock brake system
may result in a longer stopping dis-
tance than for vehicles equipped with a
conventional brake system.
W-78
CAUTION
 If the ABS warning light is on and
stays on, you may have a problemwith the ABS. In this case, howev-er, your regular brakes will worknormally.
 The ABS warning light will stay on for approximately 3 seconds afterthe ignition switch is ON. Duringthat time, the ABS will go throughself-diagnosis and the light will gooff if everything is normal. If thelight stays on, you may have aproblem with your ABS. Contactan authorized HYUNDAI dealer assoon as possible.
(Continued)
 On roads where the road surface is pitted or has different surface
height.
The safety features of an ABS (or
ESC) equipped vehicle should not
be tested by high speed driving or
cornering. This could endanger the
safety of yourself or others.
