Anti-lock brake system (ABS) (if equipped) 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 efficien-
cy from your ABS in an emergency situ-
ation, 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.
WARNING
ABS (or ESP) will not prevent acci-
dents due to improper or danger-
ous driving manoeuvres. 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 (Electronic Stability
Program System) may be longer
than for those without it in the fol-
lowing road conditions.
During these conditions the vehicle should be driven at reducedspeeds:
Rough, gravel or snow-covered roads.
With tyre chains installed.
On roads where the road surface is pitted or has different surface height.

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

Electronic stability program (ESP) (if equipped)
The Electronic Stability Program (ESP)
system is designed to stabilise the vehicle
during cornering manoeuvres. ESP
checks where you are steering and where
the vehicle is actually going. ESP applies
the brakes at individual wheels and
intervenes in the engine management
system to stabilise the vehicle. The Electronic Stability Program (ESP)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 ESP 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 ESP 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
Program System is functioning proper-
ly.
WARNING
Never drive too fast for the road
conditions or too quickly when cor-
nering. Electronic stability program
(ESP) will not prevent accidents.
Excessive speed in turns, abruptmanoeuvres and aquaplaning onwet surfaces can still result in seri-
ous accidents. Only a safe and
attentive driver can prevent acci-
dents by avoiding manoeuvres that
cause the vehicle to lose traction.
Even with ESP installed, always fol-
low all the normal precautions for
driving - including driving at safe
speeds for the conditions.

E070600AFD-EA Good braking practices
After being parked, check to be surethe 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.
Don't "ride" the brake pedal. Resting your foot on the brake pedal while driv-ing can be dangerous because it can
result in the brakes overheating and
losing their effectiveness. It also
increases the wear of the brake com-
ponents.
If a tyre goes flat while you are driving, apply the brakes gently and keep the
car pointed straight ahead while you
slow down. When you are moving
slowly enough for it to be safe to do so,
pull off the road and stop in a safe
place.
WARNING
Never press the ESP OFF button while ESP is operating. If the ESP is turned off while ESP is
operating, the vehicle may go out of
control.
To turn ESP off while driving, press
the ESP OFF button while driving
on a flat road surface.
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.

If your car is equipped with an auto-
matic transaxle, don't let your car
creep forward. To avoid creeping for-
ward, keep your foot firmly on the
brake pedal when the car is stopped.
Use caution when parking on a hill. Firmly engage the parking brake and
place the gear selector lever in P (auto-
matic transaxle) or in first or reverse
gear (manual transaxle). If your car is
facing downhill, turn the front wheels
into the kerb to help keep the car from
rolling. If your car is facing uphill, turn
the front wheels away from the kerb to
help keep the car from rolling. If there
is no kerb or if it is required by other
conditions to keep the car from rolling,
block the wheels.
Under some conditions your parking brake can freeze in the engaged posi-
tion. This is most likely to happen when
there is an accumulation of snow or ice
around or near the rear brakes or if the
brakes are wet. If there is a risk that the
parking brake may freeze, apply it only
temporarily while you put the gear
selector lever in P (automatic
transaxle) or in first or reverse gear
(manual transaxle) and block the rear
wheels so the car cannot roll. Then
release the parking brake. Do not hold the vehicle on the upgrade
with the accelerator pedal. This can
cause the transaxle to overheat.
Always use the brake pedal or parking
brake. Active geometry control suspen-
sion(AGCS) (if equipped)
The Active geometry control suspension
(AGCS) system is designed to stabilise
the vehicle during cornering manoeuvres
by controlling the rear wheel in order to
prevent oversteer. AGCS system is anelectronic system designed to help the
driver maintain vehicle control under
adverse conditions. It is not a substitute
for safe driving practices. Factors includ-
ing speed, road conditions and driver
steering input can all affect whether
AGCS will be effective in preventing a
loss of control. It is still your responsibili-
ty to drive and corner at reasonable
speeds and to leave a sufficient margin
of safety.SUSPENSION SYSTEM

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 40 km/h (25 mph).
✽✽
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 isnormal.
E090100ANF
To set cruise control speed:
1. Pull 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 40 km/h (25 mph).
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 travelling 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.
Be careful when driving downhill using the cruise control system,
which may increase the vehiclespeed.
CAUTION
With cruise control activated in a
vehicle equipped with manual
transaxle, do not shift into neutralwithout depressing the clutch pedal, since the engine will be over-revved. If this happens, depress theclutch pedal or release the cruise
control ON/OFF switch.ONF058020

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
kilometers (miles) you can get from a litre
(gallon) 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 “kangaroo” 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 tyres. Keep them inflated to the recommended pressure.
Incorrect inflation, either too much or
too little, results in unnecessary tyre
wear. Check the tyre pressures at leastonce a month.
Be sure that the wheels are aligned correctly. Improper alignment can
result from hitting kerbs or driving too
fast over irregular surfaces. Poor align-
ment causes faster tyre 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 carin accordance with the maintenance
schedule in Section 7. If you drive your
car in severe conditions, more frequentmaintenance 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 “labour” or “over-rev” the engine. Labouring is driving too slowly in toohigh 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

533
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 authorised
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 ordeath.

Hazardous driving conditions
When hazardous driving conditions are
encountered such as water, snow, ice,
mud, sand, or similar hazards, followthese 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 isstopped.
If stalled in snow, mud, or sand, use second gear. Accelerate slowly to
avoid spinning the drive wheels.
Use sand, rock salt, tyre chains, or other non-slip material under the drive
wheels to provide traction when stalled
in ice, snow, or mud. E110200AEN-EA
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.
✽✽
NOTICE
The ESP system (if equipped) should be
turned OFF prior to rocking the vehicle.
SPECIAL DRIVING CONDITIONS
WARNING - Downshifting
Downshifting with an automatic
transaxle, while driving on slipperysurfaces can cause an accident.
The sudden change in tyre speed
could cause the tyres 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 cause engine over-heating, transaxle dam-age or failure, and tyre damage.
WARNING - Spinning tyres
Do not spin the wheels, especially at speeds more than 56 km/h (35
mph). Spinning the wheels at high
speeds when the vehicle is station-
ary could cause a tyre to overheat
which could result in tyre damage
that may injure bystanders.
WARNING
If your vehicle becomes stuck in
snow, mud, sand, etc., then you
may attempt to rock the vehicle free
by moving it forward and backward.
Do not attempt this procedure if
people or objects are anywhere
near the vehicle. During the rocking
operation the vehicle may suddenly
move forward or backward as it
becomes unstuck, causing injury
or damage to nearby people orobjects.

E110500AUN-EA Driving in the rain
Rain and wet roads can make driving
dangerous, especially if you’re not pre-
pared for the slick pavement. Here are a
few things to consider when driving in the
rain:
A heavy rainfall will make it harder to
see and will increase the distance
needed to stop your vehicle, so slow
down.
Keep your windshield wiping equip- ment in good shape. Replace your
windshield wiper blades when they
show signs of streaking or missingareas on the windshield. If your tyres are not in good condition,
making a quick stop on wet pavement
can cause a skid and possibly lead to
an accident. Be sure your tyres are in
good shape.
Turn on your headlights to make it eas- ier for others to see you.
Driving too fast through large puddles can affect your brakes. If you must go
through puddles, try to drive through
them slowly.
If you believe you may have gotten your brakes wet, apply them lightly
while driving until normal braking oper-
ation returns.
E110600AUN Driving in flooded areas
Avoid driving through flooded areas
unless you are sure the water is no high-
er than the bottom of the wheel hub.
Drive through any water slowly. Allowadequate stopping distance because
brake performance may be affected.
After driving through water, dry the
brakes by gently applying them several
times while the vehicle is moving slowly. E110700AUN-EA
Highway driving
Tyres:
Adjust the tyre inflation pressures to
specification. Low tyre inflation pressures
will result in overheating and possible
failure of the tyres.
Avoid using worn or damaged tyres
which may result in reduced traction or
tyre failure.
✽✽
NOTICE
Never exceed the maximum tyre infla-
tion pressure shown on the tyres.

To keep locks from freezing
To keep the locks from freezing, squirt an
approved de-icer fluid or glycerine into
the key opening. If a lock is covered with
ice, squirt it with an approved de-icing
fluid to remove the ice. If the lock is
frozen internally, you may be able to thaw
it out by using a heated key. Handle the
heated key with care to avoid injury.
✽✽NOTICE
The operating temperature range for an
immobiliser key is between -40°C to
80°C. If you heat an immobiliser key
above 80°C to open a frozen lock, you
may damage the transponder located in
the head of the key.
E120700AFD-EA
Use approved window washer
anti-freeze in system
To keep the water in the window washer
system from freezing, add an approved
window washer anti-freeze solution in
accordance with instructions on the con-
tainer. Window washer anti-freeze is
available from an authorised HYUNDAI
dealer and most auto parts outlets. Donot use engine coolant or other types of
anti-freeze as these may damage thepaint finish.
E120800AUN-EA
Don't let your parking brake
freeze
Under some conditions your parking
brake can freeze in the engaged position.
This is most likely to happen when there
is an accumulation of snow or ice around
or near the rear brakes or if the brakes
are wet. If there is a risk the parking
brake may freeze, apply it only temporar-
ily while you put the gear selector lever in
P (automatic transaxle) or in first or
reverse gear (manual transaxle) and
block the rear wheels so the car cannot
roll. Then release the parking brake. E120900AUN
Don't let ice and snow accumu- late underneath
Under some conditions, snow and ice
can build up under the fenders and inter-
fere with the steering. When driving in
severe winter conditions where this may
happen, you should periodically check
underneath the car to be sure the move-
ment of the front wheels and the steering
components is not obstructed.
E121000AUN-EA
Carry emergency equipment
Depending on the severity of the weath-
er where you drive your car, you should
carry appropriate emergency equipment.
Some of the items you may want to carry
include tyre chains, tow straps or chains,
flashlight, emergency flares, sand, a
shovel, jumper cables, a window scraper,
gloves, ground cloth, coveralls, a blanket,etc.
