NOTICE indicates a situation
which, if not avoided, could result
in vehicle damage. Your new vehicle is designed to
obtain maximum performance with
UNLEADED FUEL, as well as mini-
mize exhaust emissions and spark
plug fouling.
Your new vehicle is designed to use
only unleaded fuel having an octane
number ((R+M)/2) of 87 (Research
Octane Number 91) or higher. (Do not
use methanol blended fuels)
To prevent damage to the engine
and engine components, never
add any fuel system cleaning
agents to the fuel tank other than
what has been specified.
Consult an authorized HYUNDAI
dealer for additional information.
Gasoline containing alcohol or
methanol
Gasohol, a mixture of gasoline and
ethanol (also known as grain alco-
hol) are being marketed along with or
instead of leaded or unleaded gaso-
line.
Do not use gasohol containing more
than 15% ethanol, and do not use
gasoline or gasohol containing any
methanol. Either of these fuels may
cause drivability problems and dam-
age to the fuel system, engine con-
trol system and emission control sys-
tem.
Discontinue using gasohol of any
kind if drivability problems occur.
NOTICE
NOTICE
CAUTION indicates a hazardous
situation which, if not avoided,
could result in minor or moder-
ate injury.

Introduction
For customers who do not use TOP
Tier Detergent Gasoline regularly,
and have problems starting or the
engine does not run smoothly, addi-
tives that you can buy separately
may be added to the gasoline. If TOP
TIER Detergent Gasoline is not avail-
able, one bottle of additive added to
the fuel tank at every 7,500 miles or
12 months is recommended.
Additives are available from your
authorized HYUNDAI dealer along
with information on how to use them.
Do not mix other additives.
Operation in foreign countries
If you are going to drive your vehicle
in another country, be sure to:
Observe all regulations regarding registration and insurance.
Determine that acceptable fuel is available. No special break-in period is needed.
By following a few simple precautions
for the first 600 miles (1,000 km) you
may add to the performance, econo-
my and life of your vehicle.
Do not race the engine.
While driving, keep your engine
speed (rpm, or revolutions per
minute) between 2,000 rpm and
4,000 rpm.
Do not maintain a single speed for long periods of time, either fast or
slow. Varying engine speed is need-
ed to properly break-in the engine.
Avoid hard stops, except in emer- gencies, to allow the brakes to seat
properly.

2-2
You will find many safety precautions
and recommendations throughout
this section, and throughout this man-
ual. The safety precautions in this sec-
tion are among the most important.
Always Wear Your Seat Belt
A seat belt is your best protection in
all types of accidents. Air bags are
designed to supplement seat belts,
not replace them. So even though
your vehicle is equipped with air bags,
ALWAYS make sure you and your
passengers wear your seat belts, and
wear them properly.
Restrain All Children
All children under age 13 should ride
in your vehicle properly restrained in
a rear seat, not the front seat. Infants
and small children should be
restrained in an appropriate child
restraint. Larger children should use
a booster seat with the lap/shoulder
belt until they can use the seat belt
properly without a booster seat.
Air Bag Hazards
While air bags can save lives, they
can also cause serious or fatal
injuries to occupants who sit too
close to them, or who are not prop-
erly restrained. Infants, young chil-
dren, and shorter adults are at the
greatest risk of being injured by an
inflating air bag. Follow all instruc-
tions and warnings in this manual.
Driver Distraction
Driver distraction presents a serious
and potentially deadly danger, espe-
cially for inexperienced drivers. Safety
should be the first concern when
behind the wheel and drivers need to
be aware of the wide array of potential
distractions, such as drowsiness,
reaching for objects, eating, personal
grooming, other passengers, and
using cellular phones.
Drivers can become distracted when
they take their eyes and attention off
the road or their hands off the wheel
to focus on activities other than driv-
ing. To reduce your risk of distraction

Safety Precautions
Adjusting the seats so that you are sit-
ting in a safe, comfortable position
plays an important role in driver and
passenger safety together with the
seat belts and air bags in an accident.
Air bags
You can take steps to reduce the risk
of being injured by an inflating air
bag. Sitting too close to an air bag
greatly increases the risk of injury in
the event the air bag inflates.The National Highway Traffic Safety
Administration (NHTSA) recommends
that drivers allow at least 10 inches
(25 cm) between the center of the
steering wheel and their chest.
Seat belts
Always fasten your seat belt before
starting any trip.
At all times, passengers should sit
upright and be properly restrained.
Infants and small children must be
restrained in appropriate child restraint
systems. Children who have outgrown
a booster seat and adults must be
restrained using the seat belts.
Do not use a cushion that
reduces friction between the seat
and the passenger. The passen-
ger’s hips may slide under the
lap portion of the seat belt during
an accident or a sudden stop.
Serious or fatal internal injuries
could result because the seat
belt cannot operate properly.
WARNING To reduce the risk of serious
injury or death from an inflating
air bag, take the following pre-
cautions:
Adjust the driver’s seat as far to
the rear as possible while main-
taining the ability to maintain
full control of the vehicle.
Adjust the front passenger seat
as far to the rear as possible.
Hold the steering wheel by the
rim with hands at the 9 o’clock
and 3 o’clock positions to mini-
mize the risk of injuries to your
hands and arms.
NEVER place anything or any-
one between the steering wheel
and the air bag.
Do not allow the front passen-
ger to place feet or legs on the
dashboard to minimize the risk
of leg injuries.

Safety system of your vehicle
Front Seats
Take the following precautions
when adjusting your seat belt:
NEVER use one seat belt for
more than one occupant.
Always position the backseat
upright with the lap portion of
the seat belt snug and low
across the hips.
NEVER allow children or small
infants to ride in a passenger’s
lap.
Do not route the seat belt
across your neck, across sharp
edges, or reroute the shoulder
strap away from your body.
Do not allow the seat belt to
become caught or jammed.
WARNING
Take the following precautions
when adjusting your seat:
NEVER attempt to adjust the
seat while the vehicle is mov-
ing. The seat could respond
with unexpected movement
and may cause loss of vehicle
control resulting in an acci-
dent.
Do not place anything under
the front seats. Loose objects
in the driver’s foot area could
interfere with the operation of
the foot pedals, causing an
accident.
Do not allow anything to inter-
fere with the normal position
and proper locking of the back-
seat.
Do not place a cigarette lighter
on the floor or seat. When you
operate the seat, gas may exit
out of the lighter causing a fire.(Continued)
WARNING
To prevent injury:
Do not adjust your seat while
wearing your seat belt.
Moving the seat cushion for-
ward may cause strong pres-
sure on your abdomen.
Do not allow your hands or
fingers to get caught in the
seat mechanisms while the
seat is moving.
CAUTION
(Continued)
Use extreme caution when
picking up small objects
trapped under the seats or
between the seat and the cen-
ter console. Your hands might
be cut or injured by the edges
of the seat mechanism.
