5 During cold weather, shifting may be
difficult 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 in the neutral posi-
tion and release the clutch. Depress
the clutch pedal back down, and then
shift into 1st or R (Reverse) gear posi-
tion.
Using the clutchThe clutch should be depressed all the
way to the floor before shifting, then
released slowly. The clutch pedal should
always be fully released while driving. Do
not rest your foot on the clutch pedal
while driving. This can cause unneces-
sary 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.DownshiftingIt is important to downshift when you
must slow down in heavy traffic or while
driving up or down steep hills.
Downshifting reduces the chance of
stalling and gives better acceleration.
When the vehicle is traveling down steep
hills, downshifting helps maintain safe
speed and prolongs brake life.
WARNING
 Before leaving the driver’s seat,always set the parking brake fully
and shut the engine off. Then
make 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 can
occur if these precautions are not
followed in the order identified.
CAUTION
 To avoid premature clutch wear and damage, do not drive withyour foot resting on the clutch pedal. Also, don’t use the clutchto hold the vehicle stopped on anuphill grade, while 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.
 When operating the clutch pedal, press the clutch pedal down fully.
If you don't press the clutch pedalfully, the clutch may be damagedor 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.
In the event of brake failure If service brakes fail to operate while 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.
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 increased
stopping distances.
(Continued)
(Continued)
 When descending a long or steephill, shift to a lower gear and
avoid continuous application of
the brakes. Continuous brake
application 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 one
side 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
while maintaining a safe forward
speed until brake performance
returns to normal.
 Always, confirm the position of the brake and accelerator pedal
before driving. If you don't check
the position of the accelerator
and brake pedal before driving,
you may depress the accelerator
instead of the brake pedal. It may
cause a serious accident.
WARNING
- Parking brake
Applying the parking brake while
the vehicle is moving at normal
speeds can cause a sudden loss of
control of the vehicle. If you must
use the parking brake to stop the
vehicle, use great caution in apply-
ing the brake.

Driving your vehicle22
5Disc 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.
■ ■Hand type
To engage the parking brake, first apply
the foot brake and then pull up the park-
ing brake lever as far as possible.
In addition it is recommended that when
parking the vehicle on an incline, the shift
lever should be in the appropriate low
gear on manual transaxle vehicles or in
the P (Park) position on automatic
transaxle vehicles.
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 a
serious accident.
CAUTION
 To avoid costly brake repairs, do not continue to drive with wornbrake pads.
 Always replace the front or rear brake pads as pairs.

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.

Driving your vehicle26
5✽
✽
NOTICEWhen 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.
Electronic stability control (ESC)The Electronic Stability control (ESC)
system is designed to stabilize the vehicle
during cornering maneuvers. ESC checks
where you are steering and where the
vehicle is actually going. ESC applies the
brakes at individual wheels and
intervenes in the engine management
system to stabilize the vehicle.
OYF059015N
WARNING
Never drive too fast for the road
conditions or too quickly when cor-
nering. Electronic stability control
(ESC) will not prevent accidents.
Excessive speed in turns, abrupt
maneuvers and hydroplaning on
wet surfaces can still result in seri-
ous accidents. Only a safe and
attentive driver can prevent acci-
dents by avoiding maneuvers that
cause the vehicle to lose traction.
Even with ESC installed, always fol-
low all the normal precautions for
driving - including driving at safe
speeds for the conditions.
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 warning light may illuminate. Pull your carover to a safe place and stop theengine.
 Restart the engine. If the ABS warning light is off, then yourABS system is normal.Otherwise, you may have a prob-lem with the ABS. Contact anauthorized HYUNDAI dealer as soon as possible.

5Indicator lightWhen ignition switch is turned to ON, the
indicator light illuminates, then goes off if
the ESC system is operating normally.
The ESC indicator light blinks whenever
ESC is operating or illuminates when
ESC fails to operate.
The ESC OFF indicator light comes on
when the ESC is turned off with the but-
ton.
ESC OFF usageWhen driving
 ESC should be turned on for daily driv-
ing whenever possible.
 To turn ESC off while driving, press the ESC OFF button while driving on a flat
road surface.
Never press the ESC OFF button while
ESC is operating (ESC indicator light
blinks).
If ESC is turned off while ESC is operat-
ing, the vehicle may slip out of control.✽ ✽ NOTICE• When operating the vehicle on a
dynamometer, ensure that the ESC is
turned off (ESC OFF light illuminat-
ed).
• Turning the ESC off does not affect ABS or brake system operation.
CAUTION
Driving with varying tire or wheel
sizes may cause the ESC system tomalfunction. When replacing tires,make sure they are the same size as your original tires.
WARNING
The Electronic Stability Control sys-
tem is only a driving aid; use pre-
cautions for safe driving by slowing
down on curved, snowy, or icy
roads. Drive slowly and don’t
attempt to accelerate whenever the
ESC indicator light is blinking, or
when the road surface is slippery.

Good braking practices
 After parking the vehicle, check to besure 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 authorized 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
Never press the ESC OFF button
while ESC is operating.
If the ESC is turned off while ESC is
operating, the vehicle may go out of
control.
To turn ESC off while driving, press
the ESC OFF button while driving
on a flat road surface.
WARNING
 Whenever you leave or park yourvehicle, always set the parking
brake as far as possible and fully
engage the vehicle's transaxle
into the P (Park) position. If the
parking brake is not fully
engaged, the vehicle may move
inadvertently and injure yourself
and others.
 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.

CRUISE indicator
➁
SET indicator
The cruise control system allows you to
program the vehicle to maintain a con-
stant speed without resting your foot on
the accelerator pedal.
This system is designed to function
above approximately 25 mph (40 km/h).
✽ ✽ NOTICEDuring normal cruise control operation,
when the SET switch is activated or
reactivated after applying the brakes,
the cruise control will energize after
approximately 3 seconds. This delay is
normal.
CRUISE CONTROL SYSTEM
WARNING
 If the cruise control is left on,
(CRUISE indicator light in the
instrument cluster illuminated)
the cruise control can be activat-
ed unintentionally. Keep the
cruise control system off
(CRUISE indicator light OFF)
when the cruise control is not in
use, to avoid inadvertently set-
ting a speed.
 Use the cruise control system only when traveling on open
highways in good weather.
 Do not use the cruise control when it may not be safe to keep
the car at a constant speed, for
instance, driving in heavy or
varying traffic, or on slippery
(rainy, icy or snow-covered) or
winding roads or over 6% up-hill
or down-hill roads.
 Pay particular attention to the driving conditions whenever
using the cruise control system.
 Be careful when driving downhill using the cruise control system,
which may increase the vehicle
speed.
OYF059030N
CAUTION
During cruise-speed driving of amanual transaxle vehicle, do notshift into neutral without depress-ing the clutch pedal, since theengine will be overrevved. If thishappens, depress the clutch pedalor release the cruise control ON-OFF switch.

537
Driving your vehicle
 Remember, your vehicle does notrequire extended warm-up. After the
engine has started, allow the engine to
run for 10 to 20 seconds prior to plac-
ing the vehicle in gear. In very cold
weather, however, give your engine a
slightly longer warm-up period.
 Don't "lug" or "over-rev" the engine. Lugging is driving too slowly in too high
a gear resulting 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 avoid-
ed by shifting at the recommended
speeds.  Use your air conditioning sparingly.
The air conditioning system is operat-
ed by engine power so your fuel econ-
omy is reduced when you use it.
 Open windows at high speeds can reduce fuel economy.
 Fuel economy is less in crosswinds and headwinds. To help offset some of
this loss, slow down when driving in
these conditions.
Keeping a vehicle in good operating con-
dition is important both for economy and
safety. Therefore, have an authorized
HYUNDAI dealer perform scheduled
inspections and maintenance.
WARNING
- Engine off dur- ing motion
Never turn the engine off to coast
down hills or anytime the vehicle is
in motion. The power steering and
power brakes will not function
properly without the engine run-
ning. Instead, keep the engine on
and downshift to an appropriate
gear for engine braking effect. In
addition, turning off the ignition
while driving could engage the
steering wheel lock resulting in
loss of vehicle steering which
could cause serious injury or
death.
