Anti-lock brake system (ABS) (if equipped)
*: Some countries use the term ESC(Electronic stability control) instead of
ESP. Please refer to the term your
country use. 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.(Continued)
On roads where the road surface
is pitted or has different surface height.
The safety features of an ABS (or
ESP/ESC*) equipped vehicle
should not be tested by high speed
driving or cornering. This could
endanger the safety of yourself or
others.
WARNING
ABS (or ESP/ESC*) will not prevent
accidents due to improper or dan-
gerous 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 (or Electronic Stability
Program system/Electronic
Stability Control*) 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. (Continued)

Driving your vehicle
✽✽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.

Electronic stability program (ESP) (if equipped)
The Electronic Stability Program (ESP)
system is designed to stabilize 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 stabilize 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, abrupt
manoeuvres and hydroplaning 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.

Driving your vehicle
Don't "ride" the brake pedal. Restingyour foot on the brake pedal whilst 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 whilst you are driving, apply the brakes gently and keep the
car pointed straight ahead whilst 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.
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 shift lever in P. 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 whilst you put the shift
lever in P 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.

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 "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. 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
whilst driving could engage the
steering wheel lock resulting in
loss of vehicle steering which
could cause serious injury ordeath.

Use high quality ethylene glycol coolant
Your vehicle is delivered with high quality
ethylene glycol coolant in the cooling
system. It is the only type of coolant that
should be used because it helps prevent
corrosion in the cooling system, lubri-
cates the water pump and prevents
freezing. Be sure to replace or replenish
your coolant in accordance with themaintenance schedule in section 7.
Before winter, have your coolant tested toassure that its freezing point is sufficient
for the temperatures anticipated during
the winter.
Check battery and cables
Winter puts additional burdens on the
battery system. Visually inspect the bat-
tery and cables as described in section
7. The level of charge in your battery can
be checked by an authorised HYUNDAI
dealer or a service station. Change to "winter weight" oil if
necessary In some climates it is recommended that
a lower viscosity "winter weight" oil be
used during cold weather. See section 8
for recommendations. If you aren't sure
what weight oil you should use, consult
an authorised HYUNDAI dealer.
Check spark plugs and ignition system
Inspect your spark plugs as described in
section 7 and replace them if necessary.
Also check all ignition wiring and compo-
nents to be sure they are not cracked,
worn or damaged in any way.
WARNING
- Tyre chains
The use of chains may adversely affect vehicle handling.
Do not exceed 30 km/h (20 mph) or the chain manufacturer’s rec-
ommended speed limit, whichev-
er is lower.
Drive carefully and avoid bumps, holes, sharp turns, and other
road hazards, which may cause
the vehicle to bounce.
Avoid sharp turns or locked- wheel braking.
CAUTION
Chains that are the wrong size or
improperly installed can damage
your vehicle's brake lines, sus-pension, body and wheels.
Stop driving and retighten the chains any time you hear themhitting the vehicle.

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.
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.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 whilst you put the shift lever in P (auto-
matic transaxle) or in first or reverse gear
(manual transaxle) and block the rear
wheels so the vehicle cannot roll. Then
release the parking brake.
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.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.
