Using ABS
To obtain the maximum benefit from your
ABS in an emergency situation, do not
attempt to modulate your brake pressure
and do not try to pump your brakes.
Depress your brake pedal as hard as
possible.
When you apply your brakes under con-
ditions which may lock the wheels, you
may hear sounds from the brakes, or feel
a corresponding sensation in the brake
pedal. This is normal and it means your
ABS is active.
ABS does not reduce the time or dis-
tance it takes to stop the vehicle.
Always maintain a safe distance from the
vehicle in front of you.
ABS will not prevent a skid that results
from sudden changes in direction, such
as trying to take a corner too fast or mak-
ing a sudden lane change. Always drive
at a safe speed for the road and weather
conditions.
ABS cannot prevent a loss of stability.
Always steer moderately when braking
hard. Severe or sharp steering wheel
movement can still cause your vehicle to
veer into oncoming traffic or off the road.On loose or uneven road surfaces, oper-
ation of the anti-lock brake system may
result in a longer stopping distance than
for vehicles equipped with a conventional
brake system.
The ABS warning light ( ) will stay on
for several seconds after the ignition
switch is in the ON position. During that
time, the ABS will go through self-diag-
nosis and the light will go off if everything
is normal. If the light stays on, you may
have a problem with your ABS. Contact
an authorized HYUNDAI dealer as soon
as possible
Information
When you jump start your vehicle because
of a drained battery, 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 mal-
functioning. Have the battery recharged
before driving the vehicle.
i
If the ABS warning light ( ) is on
and stays on, you may have a prob-
lem with the ABS. Your power
brakes will work normally. To
reduce the risk of serious injury or
death, contact your HYUNDAI deal-
er as soon as possible.
WARNING
When you drive on a road having
poor traction, such as an icy road,
and apply your brakes continuous-
ly, the ABS will be active continu-
ously and the ABS warning light
( ) may illuminate. Pull your car
over to a safe place and turn the
engine off.
Restart the engine. If the ABS warn-
ing light is off, then your ABS sys-
tem is normal.
Otherwise, you may have a problem
with your ABS system.
Contact an
authorized HYUNDAI dealer as soon
as possible.

Winter Precautions
Use high quality ethylene glycolcoolant
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 the
maintenance schedule in chapter 7.
Before winter, have your coolant tested to
assure that its freezing point is sufficient
for the temperatures anticipated during
the winter.
Change to "winter weight" oil ifnecessary
In some climates it is recommended that
a lower viscosity "winter weight" oil be
used during cold weather. See chapter 8
for recommendations. If you aren't sure
what weight oil you should use, consult
an authorized HYUNDAI dealer.
Check battery and cables
Winter puts additional burdens on the
battery system. Visually inspect the bat-
tery and cables as described in chapter
7. The level of charge in your battery can
be checked by an authorized HYUNDAI
dealer or a service station.
Check spark plugs and ignitionsystem
Inspect your spark plugs as described in
chapter 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.
Use approved window washeranti-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 authorized HYUNDAI
dealer and most auto parts outlets. Do
not use engine coolant or other types of
anti-freeze as these may damage the
paint finish.
Do not let your parking brakefreeze
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 and block the rear wheels so the car
cannot roll. Then release the parking
brake.
Do not let ice and snow accu-mulate 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.
