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 steep
hill, 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.

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-covered
roads.
 With tire chains installed.

✽
✽
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.
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 car
over to a safe place and stop the
engine.
 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
authorized HYUNDAI dealer as
soon as possible.

Driving your vehicle
The Electronic Stability Control (ESC)
system is an electronic system designed
to help the driver maintain vehicle control
under adverse conditions. It is not a
substitute for safe driving practices.
Factors including speed, road conditions
and driver steering input can all affect
whether ESC will be effective in
preventing a loss of control. It is still your
responsibility to drive and corner at
reasonable speeds and to leave a
sufficient margin of safety.
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 ESC is active.
✽
✽
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 Electronic Stability
Control System is functioning properly.
ESC operation
ESC ON condition
 When the ignition is turned
ON, ESC and ESC OFF indi-
cator lights illuminate for
approximately 3 seconds,
then ESC is turned on.
 Press the ESC OFF button
for at least half a second after
turning the ignition ON to turn
ESC off. (ESC OFF indicator
will illuminate). To turn the
ESC on, press the ESC OFF
button (ESC OFF indicator
light will go off).
 When starting the engine,
you may hear a slight ticking
sound. This is the ESC per-
forming an automatic system
self-check and does not indi-
cate a problem.
When operating
When the ESC is in operation,
ESC indicator light blinks.
 When the Electronic Stability
Control is operating properly,
you can feel a slight pulsation
in the vehicle. This is only the
effect of brake control and
indi-
cates nothing unusual.
 When moving out of the mud
or driving on a slippery road,
pressing the accelerator
pedal may not cause the
engine rpm (revolutions per
minute) to increase.
ESC operation off
ESC OFF state
 To cancel ESC operation,
press the ESC OFF button
(ESC OFF indicator light illu-
minates).
 If the ignition switch is turned
to LOCK position when ESC
is off, ESC remains off. Upon
restarting the engine, the
ESC will automatically turn
on again.

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 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 your
vehicle, 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).
✽
✽
NOTICE
• During normal cruise control opera-
tion, when the SET switch is activated
or reactivated after applying the
brakes, the cruise control will ener-
gize after approximately 3 seconds.
This delay is normal.
• To activate cruise control, depress the
brake pedal at least once after turning
the ignition switch to the ON position
or starting the engine. This is to check
if the brake switch which is important
part to cancel cruise control is in nor-
mal condition.
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 a
manual transaxle vehicle, do not
shift into neutral without depress-
ing the clutch pedal, since the
engine will be overrevved. If this
happens, depress the clutch pedal
or release the cruise control ON-
OFF switch.

Your vehicle's fuel economy depends
mainly on your style of driving, where you
drive and when you drive.
Each of these factors affects how many
miles (kilometers) you can get from a gal-
lon (liter) of fuel. To operate your vehicle
as economically as possible, use the fol-
lowing driving suggestions to help save
money in both fuel and repairs:
 Drive smoothly. Accelerate at a moder-
ate 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 unneces-
sarily. Avoid heavy traffic whenever
possible. Always maintain a safe dis-
tance from other vehicles so you can
avoid unnecessary braking. This also
reduces brake wear.
 Drive at a moderate speed. The faster
you drive, the more fuel your car uses.
Driving at a moderate speed, especial-
ly on the highway, is one of the most
effective ways to reduce fuel consump-
tion.
 Don't "ride" the brake pedal. This can
increase fuel consumption and also
increase wear on these components.
In addition, driving with your foot rest-
ing on the brake pedal may cause the
brakes to overheat, which reduces
their effectiveness and may lead to
more serious consequences.
 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.
 Be sure that the wheels are aligned
correctly. Improper alignment can
result from hitting curbs or driving too
fast over irregular surfaces. Poor align-
ment causes faster tire wear and may
also result in other problems as well as
greater fuel consumption.
 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 7. If you drive your
car in severe conditions, more frequent
maintenance is required (see section 7
for details).
 Keep your car clean. For maximum
service, your vehicle should be kept
clean and free of corrosive materials. It
is especially important that mud, dirt,
ice, etc. not be allowed to accumulate
on the underside of the car. This extra
weight can result in increased fuel con-
sumption and also contribute to corro-
sion.
 Travel lightly. Don't carry unnecessary
weight in your car. Weight reduces fuel
economy.
 Don't let the engine idle longer than
necessary. If you are waiting (and not
in traffic), turn off your engine and
restart only when you're ready to go.
