Driving your vehicle
During cold weather, shifting may bedifficult until the transaxle lubricant is
warmed up. This is normal and not
harmful to the transaxle.
If you've come to a complete stop and it's hard to shift into 1st or R(Reverse),
leave the shift lever at N(Neutral) posi-
tion and release the clutch. Press the
clutch pedal back down, and then shift
into 1st or R(Reverse) gear position.Using the clutch
The clutch should be pressed all the way
to the floor before shifting, then released
slowly. The clutch pedal should always be
fully released whilst driving. Do not rest
your foot on the clutch pedal whilst driv-
ing. This can cause unnecessary wear.
Do not partially engage the clutch to hold
the vehicle on an incline. This causes
unnecessary wear. Use the foot brake or
parking brake to hold the vehicle on an
incline. Do not operate the clutch pedal
rapidly and repeatedly.
CAUTION
To avoid premature clutch wear
and damage, do not drive with
your foot resting on the clutch pedal. Also, don’t use the clutchto hold the vehicle stopped on anuphill grade, whilst waiting for a
traffic light, etc.
Do not use the shift lever as a handrest during driving, as thiscan result in premature wear ofthe transaxle shift forks.
WARNING
Before leaving the driver’s seat, always set the parking brake fully
and shut the engine off. Thenmake sure the transaxle is shifted
into 1st gear when the vehicle is
parked on a level or uphill grade,
and shifted into R (Reverse) on a
downhill grade. Unexpected and
sudden vehicle movement canoccur if these precautions are not
followed in the order identified.
If your vehicle has a manual transaxle not equipped with a
ignition lock switch, it may moveand cause a serious accident
when starting the engine without
depressing the clutch pedalwhilst the parking brake is
released and the shift lever not inthe N(Neutral) position.
CAUTION
When operating the clutch pedal,
press the clutch pedal down fully. Ifyou don’t press the clutch pedal fully, the clutch may be damaged or
noise may occur.

Power brakes
Your vehicle has power-assisted brakes
that adjust automatically through normal
usage.
In the event that the power-assisted
brakes lose power because of a stalled
engine or some other reason, you can
still stop your vehicle by applying greater
force to the brake pedal than you nor-
mally would. The stopping distance, how-
ever, will be longer.
When the engine is not running, the
reserve brake power is partially depleted
each time the brake pedal is applied. Do
not pump the brake pedal when the
power assist has been interrupted.
Pump the brake pedal only when neces-
sary to maintain steering control on slip-
pery surfaces. BRAKE SYSTEM
WARNING
- Brakes
Do not drive with your foot rest- ing on the brake pedal. This will create abnormal high brake tem-
peratures, excessive brake lining
and pad wear, and increasedstopping distances.
When descending a long or steep hill, shift to a lower gear and
avoid continuous application of
the brakes. Continuous brakeapplication will cause the brakes
to overheat and could result in a
temporary loss of braking per-
formance.
Wet brakes may impair the vehi- cle’s ability to safely slow down;
the vehicle may also pull to oneside when the brakes are applied.
Applying the brakes lightly will
indicate whether they have been
affected in this way. Always test
your brakes in this fashion after
driving through deep water. To
dry the brakes, apply them lightly
whilst maintaining a safe forward
speed until brake performancereturns to normal.
(Continued)(Continued)
Always, confirm the position ofthe brake and accelerator pedal
before driving. If you don't checkthe position of the accelerator
and brake pedal before driving,
you may depress the accelerator
instead of the brake pedal. It maycause a serious accident.

523
Driving your vehicle
In the event of brake failure
If service brakes fail to operate whilst the
vehicle is in motion, you can make an
emergency stop with the parking brake.
The stopping distance, however, will be
much greater than normal.
Disc brakes wear indicator
Your vehicle has disc brakes.
When your brake pads are worn and new
pads are required, you will hear a high-
pitched warning sound from your front
brakes or rear brakes. You may hear this
sound come and go or it may occur
whenever you depress the brake pedal.
Please remember that some driving con-
ditions or climates may cause a brake
squeal when you first apply (or lightly
apply) the brakes. This is normal and
does not indicate a problem with your
brakes.Parking brake
Applying the parking brake
Foot type
To engage the parking brake, first apply
the foot brake and then depress the park-
ing brake pedal down as far as possible.
WARNING- Parking brake
Applying the parking brake whilst
the vehicle is moving at normal
speeds can cause a sudden loss of
control of the vehicle. If you mustuse the parking brake to stop the
vehicle, use great caution in apply-
ing the brake.
WARNING - Brake wear
This brake wear warning sound
means your vehicle needs service.
If you ignore this audible warning,
you will eventually lose braking
performance, which could lead to aserious accident.
CAUTION
To avoid costly brake repairs, do not continue to drive with wornbrake pads.
Always replace brake pads as complete front or rear axle sets.

Driving your vehicle
Hand type
To release the parking brake, first apply
the foot brake and pull up the parking
brake lever slightly. Secondly depress the
release button (1) and lower the parking
brake lever (2) whilst holding the button.If the parking brake does not release or
does not release all the way, have the
system checked by an authorised
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 ignition switch in the START or ONposition.
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 whilst
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 whilst operating the
vehicle and only continue to drive the
vehicle until you can reach a safe loca-
tion or repair shop.
OYF059024R
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 parkingbrake 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 orpedestrians.

✽✽NOTICE
A 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.
✽✽ NOTICE
When you jump start your vehicle
because of a drained battery, the engine
may not run as smoothly and the ABS
warning light may turn on at the same
time. This happens because of the low
battery voltage. It does not mean your
ABS is malfunctioning.
 Do not pump your brakes!
 Have the battery recharged before driving the vehicle.
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 work normally.
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 go off if everything is normal. If thelight stays on, you may have aproblem with your ABS. Contactan authorised HYUNDAI dealer assoon as possible.
CAUTION
When you drive on a road having poor traction, such as an icy road,
and operate your brakes continu- ously, the ABS will be active con-tinuously and the ABS warninglight may illuminate. Pull your car
over to a safe place and stop theengine.
Restart the engine. If the ABS warning light is off, then your
ABS system is normal. Otherwise, you may have a prob-lem with the ABS. Contact an authorised HYUNDAI dealer as
soon as possible.

Hill-start assist control (HAC) (if equipped)
A vehicle has the tendency to slip back
on a steep hill when it starts to go after
stopping. The Hill-start Assist Control
(HAC) prevents the vehicle from slipping
back by operating the brakes automati-
cally for about 2 seconds. The brakes are
released when the accelerator pedal is
depressed or after about 2 seconds.
✽✽
NOTICE
 The HAC does not operate when the transaxle shift lever is in the P (Park)
or N (Neutral) position.
 The HAC activates even though the ESP(or ESC) is off but it does not acti-
vate when the ESP(or ESC) has mal-
functioned.
Good braking practices After parking the vehicle, check to be
sure the parking brake is not engaged
and that the parking brake indicator
light is out before driving away.
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
an authorised HYUNDAI dealer for
assistance.
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.
WARNING
The HAC is activated only for about
2 seconds, so when the vehicle is
starting off always depress theaccelerator pedal.
WARNING
Whenever leaving vehicle or parking, always set the parking
brake as far as possible and fully
engage the vehicle's transaxle
into the park position. Vehicles
not fully engaged in park with the
parking brake set are at risk for
moving inadvertently and injur-
ing yourself or others.
All vehicles should always have the parking brake fully engaged
when parking to avoid inadver-
tent movement of the car whichcan injure occupants or pedestri-ans.
