Safety features of your vehicle
The curtain air bags are designed to
deploy only during certain side impact
collisions, depending on the crash sever-
ity, angle, speed and impact. The curtain
air bags are not designed to deploy in all
side impact situations, collisions from the
front or rear of the vehicle or in most
rollover situations.
WARNING
• In order for side and curtain airbags to provide the best protec-
tion, front seat occupants and
outboard rear occupants should
sit in an upright position with the
seat belts properly fastened.
Importantly, children should sit in
a proper child restraint system in
the rear seat.
• When children are seated in the rear outboard seats, they must be
seated in the proper child
restraint system. Make sure to
put the child restraint system as
far away from the door side as
possible, and secure the child
restraint system in a locked posi-
tion.
• Do not allow the passengers to lean their heads or bodies onto
doors, put their arms on the
doors, stretch their arms out of
the window, or place objects
between the doors and passen-
gers when they are seated on
seats equipped with side and/or
curtain air bags.
(Continued)
(Continued)
• Never try to open or repair anycomponents of the side curtain
air bag system. This should only
be done by an authorized
HYUNDAI dealer.
Failure to follow the above instruc-
tions can result in injury or death to
the vehicle occupants in an acci-
dent.

Safety features of your vehicle
SRS CareThe SRS is virtually maintenance-free
and so there are no parts you can safely
service by yourself. If the SRS air bag
warning light " " does not illuminate,
when you turn the ignition on, or continu-
ously remains on, have your vehicle
immediately inspected by an authorized
HYUNDAI dealer.
Any work on the SRS system, such as
removing, installing, repairing, or any
work on the steering wheel, the front
passenger's panel, front seats and roof
rails must be performed by an authorized
HYUNDAI dealer. Improper handling of
the SRS system may result in serious
personal injury.

WARNING
• Modification to SRS componentsor wiring, including the addition
of any kind of badges to the pad
covers or modifications to the
body structure, can adversely
affect SRS performance and lead
to possible injury.
• Not only the modification of the parts where the SRS sensors are
but also the modification of other
parts of the vehicle may affect the
SRS performance and lead to
possible injury.
• For cleaning the air bag pad cov- ers, use only a soft, dry cloth or
one which has been moistened
with plain water. Solvents or
cleaners could adversely affect
the air bag covers and proper
deployment of the system.
•No objects should be placed over
or near the air bag modules on the
steering wheel, instrument panel,
and the front passenger's panel
above the glove box, because any
such object could cause harm if the
vehicle is in a crash severe enough
to cause the air bags to inflate.
(Continued)
(Continued)
• If the air bags inflate, they must be replaced by an authorized
HYUNDAI dealer.
• Do not tamper with or disconnect SRS wiring, or other components
of the SRS system. Doing so
could result in injury, due to acci-
dental inflation of the air bags or
by rendering the SRS inopera-
tive.
• If components of the air bag sys- tem must be discarded, or if the
vehicle must be scrapped, certain
safety precautions must be
observed. An authorized
HYUNDAI dealer knows these
precautions and can give you the
necessary information. Failure to
follow these precautions and pro-
cedures could increase the risk
of personal injury.
• If your car was flooded and has soaked carpeting or water on the
flooring, you shouldn't try to start
the engine; have the car towed to
an authorized HYUNDAI dealer.

3Additional safety precautions• Never let passengers ride in the
cargo area or on top of a folded-
down back seat. All occupants should
sit upright, fully back in their seats with
their seat belts on and their feet on the
floor.
• Passengers should not move out of
or change seats while the vehicle is
moving. A passenger who is not wear-
ing a seat belt during a crash or emer-
gency stop can be thrown against the
inside of the vehicle, against other
occupants, or out of the vehicle.
• Each seat belt is designed to
restrain one occupant. If more than
one person uses the same seat belt,
they could be seriously injured or killed
in a collision.
• Do not use any accessories on seat
belts. Devices claiming to improve
occupant comfort or reposition the seat
belt can reduce the protection provided
by the seat belt and increase the
chance of serious injury in a crash.
• Passengers should not place hard
or sharp objects between them-
selves and the air bags. Carrying
hard or sharp objects on your lap or in
your mouth can result in injuries if an
air bag inflates. •
Keep occupants away from the air
bag covers. All occupants should sit
upright, fully back in their seats with
their seat belts on and their feet on the
floor. If occupants are too close to the
air bag covers, they could be injured if
the air bags inflate.
• Do not attach or place objects on or
near the air bag covers. Any object
attached to or placed on the front or
side air bag covers could interfere with
the proper operation of the air bags.
• Do not modify the front seats.
Modification of the front seats could
interfere with the operation of the sup-
plemental restraint system sensing
components or side air bags.
• Do not place items under the front
seats. Placing items under the front
seats could interfere with the operation
of the supplemental restraint system
sensing components and wiring har-
nesses.
• Never hold an infant or child on your
lap. The infant or child could be seri-
ously injured or killed in the event of a
crash. All infants and children should
be properly restrained in appropriate
child safety seats or seat belts in the
rear seat.
Adding equipment to or modifying
your air bag-equipped vehicleIf you modify your vehicle by changing
your vehicle's frame, bumper system,
front end or side sheet metal or ride
height, this may affect the operation of
your vehicle's air bag system.
WARNING
• Sitting improperly or out of posi- tion can cause occupants to be
shifted too close to a deploying
air bag, strike the interior struc-
ture or be thrown from the vehicle
resulting in serious injury or
death.
• Always sit upright with the seat- back in an upright position, cen-
tered on the seat cushion with
your seat belt on, legs comfort-
ably extended and your feet on
the floor.
• Be careful not to cause impact to the doors when the ignition is
ON. The air bags may inflate.

Driving your vehicle
WARNING
• Overloading your vehicle cancause heat buildup in your
vehicle's tires and possible
tire failure that could lead to a
crash.
• Overloading your vehicle can cause increased stopping dis-
tances that could lead to a
crash.
• A crash resulting from poor handling, vehicle damage, tire
failure, or increased stopping
distances could result in seri-
ous injury or death.
WARNING
- Loose cargo
Items you carry inside your
vehicle can strike and injure
occupants in a sudden stop or
turn, or in a crash.
• Put items in the cargo area of your vehicle. Try to spread the
weight evenly.
• Never stack items, like suit- cases, inside the vehicle
above the tops of the seats.
• Do not leave an unsecured child restraint in your vehicle.
• When you carry something inside the vehicle, secure it.
• Do not drive with a seat folded down unless necessary.
CAUTION
• Overloading your vehicle may
cause damage. Repairs wouldnot be covered by your warran-ty. Do not overload your vehicle.
• Using heavier suspension com- ponents to get added durabilitymight not change your weightratings. Ask your dealer to helpyou load your vehicle the right
way.

Maintenance
Temperature -A, B & C The temperature grades are A (the
highest), B and C representing the
tire’s resistance to the generation of
heat and its ability to dissipate heat
when tested under controlled condi-
tions on a specified indoor laboratory
test wheel.
Sustained high temperature can
cause the material of the tire to
degenerate and reduce tire life, and
excessive temperature can lead to
sudden tire failure. The grade C cor-
responds to a level of performance
which all passenger car tires must
meet under the Federal Motor
Vehicle Safety Standard No. 109.
Grades B and A represent higher
levels of performance on the labora-
tory test wheel than the minimum
required by law.Tire terminology and definitions
Air Pressure
: The amount of air
inside the tire pressing outward on
the tire. Air pressure is expressed in
pounds per square inch (psi) or kilo-
pascal (kPa).
Accessory Weight : This means the
combined weight of optional acces-
sories. Some examples of optional
accessories are, automatic
transaxle, power seats, and air con-
ditioning.
Aspect Ratio : The relationship of a
tire's height to its width.
Belt: A rubber coated layer of cords
that is located between the plies and
the tread. Cords may be made from
steel or other reinforcing materials.
Bead : The tire bead contains steel
wires wrapped by steel cords that
hold the tire onto the rim.
Bias Ply Tire : A pneumatic tire in
which the plies are laid at alternate
angles less than 90 degrees to the
centerline of the tread.
WARNING - Tire temperature
The temperature grade for this
tire is established for a tire that
is properly inflated and not
overloaded. Excessive speed,
underinflation, or excessive
loading, either separately or in
combination, can cause heat
build-up and possible sudden
tire failure. This can cause loss
of vehicle control and serious
injury or death.

• When cleaning underneath the car,give particular attention to the compo-
nents under the fenders and other
areas that are hidden from view. Do a
thorough job; just dampening the accu-
mulated mud rather than washing it
away will accelerate corrosion rather
than prevent it. Water under high pres-
sure and steam are particularly effec-
tive in removing accumulated mud and
corrosive materials.
• When cleaning lower door panels, rocker panels and frame members, be
sure that drain holes are kept open so
that moisture can escape and not be
trapped inside to accelerate corrosion.
Keep your garage dry
Don't park your car in a damp, poorly
ventilated garage. This creates a favor-
able environment for corrosion. This is
particularly true if you wash your car in
the garage or drive it into the garage
when it is still wet or covered with snow,
ice or mud. Even a heated garage can
contribute to corrosion unless it is well
ventilated so moisture is dispersed. Keep paint and trim in good condition
Scratches or chips in the finish should be
covered with "touch-up" paint as soon as
possible to reduce the possibility of cor-
rosion. If bare metal is showing through,
the attention of a qualified body and paint
shop is recommended.
Bird droppings : Bird droppings are high-
ly corrosive and may damage painted
surfaces in just a few hours. Always
remove bird droppings as soon as possi-
ble.
Don't neglect the interior
Moisture can collect under the floor mats
and carpeting to cause corrosion. Check
under the mats periodically to be sure
the carpeting is dry. Use particular care if
you carry fertilizers, cleaning materials or
chemicals in the car.
These should be carried only in proper
containers and any spills or leaks should
be cleaned up, flushed with clean water
and thoroughly dried.
Interior careInterior general precautions Prevent caustic solutions such as per-
fume and cosmetic oil from contacting
the dashboard because they may cause
damage or discoloration. If they do con-
tact the dashboard, wipe them off imme-
diately. See the instructions that follow for
the proper way to clean vinyl.
CAUTION
• Never allow water or other liquids
to come in contact with electri-cal/electronic components insidethe vehicle as this may damage them.
• When cleaning leather products (steering wheel, seats etc.), useneutral detergents or low alcoholcontent solutions. If you use high alcohol content solutions oracid/alkaline detergents, the color of the leather may fade or the sur-face may get stripped off.
