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.
✽ ✽
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.

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)
The safety features of an ABS
(ESC) equipped vehicle should not
be tested by high speed driving or
cornering. This could endanger the
safety of yourself or others.

✽
✽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)
(If equipped)
The Electronic Stability Control (ESC)
system is designed to stabilize the vehicle
during cornering manuevers. 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.
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 assoon as possible.

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.

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.

ESC OFF usage
When driving
It’s a good idea to keep the ESC turned
on for daily driving whenever possible.
To turn ESC off while driving, press the ESC OFF button while driving on a flat
road surface.
Never press 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). If the ESC is left on, it may pre-
vent the vehicle speed from increas-
ing, and result in false diagnosis.
• Turning the ESC off does not affect ABS or brake system operation.
Good braking practices
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.
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.

The cruise control system allows you to
program the vehicle to maintain a con-
stant speed without pressing the acceler-
ator pedal.
This system is designed to function
above approximately 25 mph (40 km/h).
✽ ✽
NOTICE
During 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.
To set cruise control speed:
1. Push the CRUISE ON-OFF button on
the steering wheel to turn the system
on. The CRUISE indicator light in the
instrument cluster will illuminate.
2. Accelerate to the desired speed, which must be more than 25 mph (40 km/h).
CRUISE CONTROL SYSTEM (IF EQUIPPED)
WARNING
If the cruise control is left on,(CRUISE indicator light in the
instrument cluster illuminated)
the cruise control can be
switched on accidentally. 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.
(Continued)
(Continued)
Pay particular attention to thedriving conditions whenever
using the cruise control system.
During cruise-speed driving of a manual transaxle vehicle, do not
shift into neutral without
depressing the clutch pedal,
since the engine will be over-
revved. 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 or clutch pedal.
This can increase fuel consumption
and also increase wear on these com-
ponents. In addition, driving with your
foot resting 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.
Remember, your vehicle does not require 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.
ECONOMICAL OPERATION

531
Driving your vehicle
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.

Hazardous driving conditions
When hazardous driving conditions are
encountered such as water, snow, ice,
mud, sand, or similar hazards, follow
these suggestions:
Drive cautiously and allow extra dis-
tance for braking.
Avoid sudden movements in braking or steering.
When braking with non-ABS brakes pump the brake pedal with a light up-
and-down motion until the vehicle is
stopped.
If stalled in snow, mud, or sand, use second gear. Accelerate slowly to
avoid spinning the drive wheels.
Use sand, rock salt, tire chains, or other non-slip material under the drive
wheels to provide traction when stalled
in ice, snow, or mud.
Rocking the vehicle
If it is necessary to rock the vehicle to
free it from snow, sand, or mud, first turn
the steering wheel right and left to clear
the area around your front wheels. Then,
shift back and forth between R (Reverse)
and any forward gear in vehicles
equipped with an automatic transaxle. Do
not race the engine, and spin the wheels
as little as possible. If you are still stuck
after a few tries, have the vehicle pulled
out by a tow vehicle to avoid engine over-
heating and possible damage to the
transaxle.
SPECIAL DRIVING CONDITIONS
WARNING - Downshifting
Downshifting with an automatic
transaxle, while driving on slippery
surfaces can cause an accident.
The sudden change in tire speed
could cause the tires to skid. Be
careful when downshifting on slip-
pery surfaces.
WARNING - ABS
Do not pump the brake pedal on a
vehicle equipped with ABS.
CAUTION
Prolonged rocking may causeengine over-heating, transaxle dam-age or failure, and tire damage.
CAUTION
The ESC system (if equipped) should be turned OFF prior to rock-ing the vehicle.
WARNING- Spinning tires
Do not spin the wheels, especially
at speeds more than 35 mph (56
km/h). Spinning the wheels at high
speeds when the vehicle is station-
ary could cause a tire to overheat
which could result in tire damage
that may injure bystanders.

Higher speed motoring
Tires:
Adjust the tire inflation pressures to
specification. Low tire inflation pressures
will result in overheating and possible
failure of the tires.
Avoid using worn or damaged tires which
may result in reduced traction or tire fail-
ure.
✽ ✽
NOTICE
Never exceed the maximum tire inflation
pressure shown on the tires.
Fuel, engine coolant and engine oil:
High speed travel consumes more fuel
than urban motoring. Do not forget to
check both engine coolant and engine
oil.
Drive belt:
A loose or damaged drive belt may result
in overheating of the engine.
WARNING
Underinflated or overinflated
tires can cause poor handling,
loss of vehicle control, and sud-
den tire failure leading to acci-
dents, injuries, and even death.
Always check the tires for proper
inflation before driving. For prop-
er tire pressures, refer to section
8, “Tires and wheels”.
Driving on tires with no or insuffi- cient tread is dangerous. Worn-
out tires can result in loss of
vehicle control, collisions, injury,
and even death. Worn-out tires
should be replaced as soon as
possible and should never be
used for driving. Always check
the tire tread before driving your
car. For further information and
tread limits, refer to section 7,
“Tires and wheels”.
