Infant or small child
All 50 states have child restraint laws. You
should be aware of the specific require-
ments in your state. Child and/or infant
seats must be properly placed and
installed in the rear seat. For more infor-
mation about the use of these restraints,
refer to “Child restraint system” in this
section.✽ ✽
NOTICE
Small children are best protected from
injury in an accident when properly
restrained in the rear seat by a child
restraint system that meets the require-
ments of the Federal Motor Vehicle
Safety Standards. Before buying any
child restraint system, make sure that it
has a label certifying that it meets
Federal Motor Vehicle Safety Standard
213. The restraint must be appropriate
for your child's height and weight.
Check the label on the child restraint for
this information. Refer to “Child
restraint system” in this section.
Larger children
Children who are too large for child
restraint systems should always occupy
the rear seat and use the available
lap/shoulder belts. The lap portion should
be fastened snug on the hips and as low
as possible. Check belt fit periodically. A
child's squirming could put the belt out of
position. Children are afforded the most
safety in the event of an accident when
they are restrained by a proper restraint
system in the rear seat. If a larger child
(over age 12) must be seated in the front
seat, the child should be securely
restrained by the available lap/shoulder
belt and the seat should be placed in the
rearmost position. Children age 12 and
under should be restrained securely in
the rear seat. NEVER place a child age
12 and under in the front seat. NEVER
place a rear facing child seat in the front
seat of a vehicle.
WARNING
Every person in your vehicle needs
to be properly restrained at all
times, including infants and chil-
dren. Never hold a child in your
arms or lap when riding in a vehi-
cle. The violent forces created dur-
ing a crash will tear the child from
your arms and throw the child
against the interior. Always use a
child restraint appropriate for your
child's height and weight.

Main components of occupant
classification system
A detection device located within thefront passenger seat frame.
Electronic system to determine whether the front passenger air bag system
should be activated or deactivated.
A warning light located on the instru- ment panel which illuminates the words
PASS AIR BAG "OFF" indicating the
front passenger air bag system is deac-
tivated.
The instrument panel air bag warning light is interconnected with the occupant
classification system.
If the front passenger seat is occupied by
a person that the system determines to be
of adult size, and he/she sits properly (sit-
ting upright with the seatback in an upright
position, centered on the seat cushion
with their seat belt on, legs comfortably
extended and their feet on the floor), the
PASS AIR BAG "OFF" indicator will be
turned off and the front passenger's air
bag will be able to inflate, if necessary, in
frontal crashes. You will find the PASS AIR BAG "OFF"
indicator on the center facia panel. This
system detects the conditions 1~4 in the
following table and activates or deacti-
vates the front passenger air bag based
on these conditions.
Always be sure that you and all vehicle
occupants are seated and restrained
properly (sitting upright with the seat in
an upright position, centered on the seat
cushion, with the person's legs comfort-
ably extended, feet on the floor, and
wearing the safety belt properly) for the
most effective protection by the air bag
and the safety belt.
The OCS may not function properly if
the passenger takes actions which can
affect the classification system. These
include:
(1) Failing to sit in an upright position.
(2) Leaning against the door or center console.
(3) Sitting towards the sides or the front of the seat.
(4) Putting legs on the dashboard or resting them on other locations
which reduce the passenger weight
on the front seat.
(5) Improperly wearing the safety belt.
(6) Reclining the seat back.

Condition and operation in the front passenger occupant classification system
*1) The system judges a person of adult size as an adult. When a smaller adult sits in
the front passenger seat, the system may recognize him/her as a child depending
on his/her physique and posture.
*2) Do not allow children to ride in the front passenger seat. When a larger child who has outgrown a child restraint system sits in the front passenger seat, the system
may recognize him/her as an adult depending upon his/her physique or sitting
position.
*3) Never install a child restraint system on the front passenger seat.
*4) The PASSENGER AIR BAG "OFF" indicator may turn on or off when a child above 12 months to 12 years old (with or without child restraint system) sits in the front
passenger seat. This is a normal condition.
WARNING
Riding in an improper position or
placing weight on the front passen-
ger's seat when it is unoccupied by
a passenger adversely affects the
occupant classification system
(OCS).

Do not place an electronic devicesuch as a laptop computer on the
front passenger seat. Its elec-
tronic field may cause the OCS to
switch to the "on" condition and
thus allow the passenger air bag
to deploy needlessly in a colli-
sion, increasing your repair
costs.
A smaller-stature adult in the front passenger’s seat who is not
seated correctly (for example:
seat excessively reclined, leaning
on the door or center console, or
hips shifted forward in the seat)
can cause a condition where the
occupant classification system
senses less weight than if the
occupant were seated properly
(sitting upright with the seatback
in an upright position, centered
on the seat cushion with their
seat belt on, legs comfortably
extended and their feet on the
floor).
This condition can result in an
adult potentially being misclassi-
fied as a child and illumination of
the PASS AIR BAG "OFF" indica-
tor.(Continued)
Accident statistics show thatchildren are safer if they are
restrained in the rear, as opposed
to the front seat. It is recom-
mended that child restraints be
secured in a rear seat, including
an infant riding in a rear-facing
infant seat, a child riding in a for-
ward-facing child seat and an
older child riding in a booster
seat.
Air bags can only be used once – have an authorized HYUNDAI
dealer replace the air bag imme-
diately after deployment.
The occupant classification sys- tem may not work properly if
water, coffee or any other liquid
including rain gets on the seat.
Keep the front seat dry at all
times.
(Continued)(Continued)
If the PASS AIR BAG "OFF" indi-cator is illuminated when the
front passenger's seat is occu-
pied by an adult and he/she sits
properly (sitting upright with the
seatback in an upright position,
centered on the seat cushion
with their seat belt on, legs com-
fortably extended and their feet
on the floor), have that person sit
in the rear seat.
Do not modify or replace the front passenger seat. Don't place any-
thing on or attach anything such
as a blanket or seat heater to the
front passenger seat. This can
adversely affect the occupant
classification system.
Do not sit on sharp objects such as tools when occupying the
front passenger seat. This can
adversely affect the occupant
classification system.
Do not use accessory seat cov- ers on the front seats.

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.

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 the
maintenance schedule in section 7.
Before winter, have your coolant tested to
assure 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 authorized 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 authorized 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- Tire chains
The use of chains may adversely
affect vehicle handling.
Do not exceed 20 mph (30 km/h) 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 damageyour vehicle's brake lines, sus-pension, body and wheels.
Stop driving and retighten the chains any time you hear themhitting the vehicle.
