B020A01S-AATBREAKING IN YOUR NEW HYUNDAI
During the First 1,200 Miles (2,000 Km)
No formal "break-in" procedure is required with
your new Hyundai. However, you can contrib-
ute to the economical operation and durability of
your Hyundai by observing the following recom-
mendations during the first 1,200 miles (2,000
km).
o Don't drive faster than 55 MPH (88 km/h).
o While driving, keep your engine speed (rpm,
or revolutions per minute) between 2,000
rpm and 4,000 rpm.
o Use moderate acceleration. Don't start
quickly or depress the accelerator pedal
fully.
o For the first 200 miles (300 km), try to avoid
hard stops.
o Don't lug the engine (in other words, don't
drive so slowly in too high a gear that the
engine "bucks"-shift to a lower gear).
B030A01Y-AATKEYS
B030B01A-AAT
Record Your Key Number
o Whether going fast or slow, vary your speed
from time to time.
o Don't let the engine idle longer than 3 minutes
at one time.
o Don't tow a trailer during the first 1,200 miles
(2,000 km) of operation.
A code number is stamped on the number plate
that came with the keys to your Hyundai. This
key number plate should not be left with the keys
but kept in a safe place, not in the vehicle. The
key number should also be recorded in a place
where it can be found in an emergency.
If you need additional keys, or if you should lose
your keys, your authorized Hyundai dealer can
make new keys if you can supply the key
number. For greater convenience, your Hyundai has
two master keys and a sub key. The master
keys will open all locks on your vehicle. The sub
key will only function in the ignition and the door
locks.
Leaving your sub key with a parking attendant
will ensure that your vehicle's trunk, trunk lid
release, glovebox compartment and rear trunk
access may not be unlocked in your absence.NOTE:Before leaving your sub key with a parking
attendant, make sure that the lock levers of
the rear seat back lock and the trunk lid lock
are switched to the "LOCK" position.

B110A01Y-AATFOLDING REAR SEATBACKS
(If installed)
o To unlock the seatback, depress the
seatback locking button, then pull forward on
the seatback panel.
o When you return the seatback to its upright
position, always be sure it has locked into
position by pulling and pushing on the top of
the seatback.
WARNING:The purpose of the folding rear seatbacks
is to allow you to carry longer objects than
could otherwise be accommodated. Do not
allow passengers to sit on top of the folded
down seatback while the car is moving as
this is not a proper seating position and no
seat belts are available for use. This could
result in serious injury or death in case of an
accident or sudden stop. Objects carried
on the folded down seatback should not
extend higher than the top of the front
seats. This could allow cargo to slide for-
ward and cause injury or damage during
sudden stops.
B120A01Y-AATREAR SEATBACK LOCK
If the rear seatback lock lever (located on the
backside of the rear seatback) is in the "LOCK"
position when the rear seatbacks are closed, it
will not be possible to fold the rear seatback by
using the release lock lever. In this instance,
move the lock lever to the "FREE" position and
fold the rear seatback. The rear seatback lock
lever is designed to provide protection from
unauthorized entry into the trunk.HEF-135HEF-137

B230A02Y-AATCHILD RESTRAINT SYSTEM
Children riding in the car should sit in the rear
seat and must always be properly restrained to
minimize the risk of injury in an accident, sudden
stop or sudden maneuver. According to acci-
dent statistics provided by the National High-
way Traffic Safety Administration (NHTSA),
children are safer when properly restrained in
the rear seats than in the front seat. Larger
children should use one of the seat belts pro-
vided.
All 50 states have child restraint laws. You
should be aware of the specific requirements in
your state. Child and/or infant safety seats must
be properly placed and installed in the rear seat.
You must use a commercially available child
restraint system that meets the requirements of
the Federal Motor Vehicle Safety Standards
(FMVSS).
Children could be injured or killed in a crash if
their restraints are not properly secured. For
small children and babies, a child seat or infant
seat must be used. Before buying a particular
child restraint system, make sure it fits your car
and seat belts, and fits your child. Follow all the
instructions provided by the manufacturer when
installing the child restraint system.WARNING:o A child restraint system must be placed
in the rear seat. Never install a child or
infant seat on the front passenger's seat.
Should an accident occur and cause the
passenger side airbag to deploy, it could
severely injure or kill an infant or child
seated in an infant or child seat. thus,
only use a child restraint in the rear seat
of your vehicle.
o Since a safety belt or child restraint sys-
tem can become very hot if it is left in a
closed vehicle, be sure and check the
seat cover and buckles before placing a
child there.
o When the child restraint system is not in
use, store it in the trunk or fasten it with
a safety belt so that it will not be thrown
forward in the case of a sudden stop or
an accident.
o Children who are too large to be in a child
restraint should still sit in the rear seat
and be restrained with the available lap/
shoulder belts. Never allow children to
ride in the front passenger seat.
o Always make sure that the shoulder belt
portion of the lap/shoulder belt is posi-
tioned midway over the shoulder and
never across the neck or behind the
back. Moving the child closer to the
center of the vehicle may help provide a
good shoulder belt fit. The lap belt por-tion of the lap/shoulder belt must always
be positioned as low as possible on the
child's hips, and as snug as possible.
o If the seat belt will not properly fit the
child, we recommend the use of an ap-
proved booster seat in the rear seat in
order to raise the child's seating height
so that the seat belt will properly fit the
child.
Before purchasing a booster seat, make
sure that it meets applicable Federal
Motor Vehicle Safety Standards and that
it is satisfactory for use with this vehicle.
o Never allow a child to stand up or kneel
on the seat.
o Never use an infant carrier or a child
safety seat that "hooks" over a seatback;
it may not provide adequate security in
an accident.
o Never allow a child to be held in a person's
arms while they are in a moving vehicle,
as this could result in serious injury to
the child in the event of an accident or a
sudden stop. Holding a child in a moving
vehicle does not provide the child with
any means of protection during an acci-
dent, even if the person holding the child
is wearing a seat belt.

B260H02A-AATParking Brake/Brake Fluid Level
Warning Lightadding fluid, if no other trouble is found, the car
should be immediately and carefully driven to a
Hyundai dealer for inspection. If further trouble
is experienced, the vehicle should not be driven
at all but taken to a dealer by a professional
towing service or some other safe method.
Your Hyundai is equipped with dual-diagonal
braking systems. This means you still have
braking on two wheels even if one of the dual
systems should fail. With only one of the dual
systems working, more than normal pedal travel
and greater pedal pressure are required to stop
the car. Also, the car will not stop in as short a
distance with only half of the brake system
working. If the brakes fail while you are driving,
shift to a lower gear for additional engine braking
and stop the car as soon as it is safe to do so.
WARNING:If you suspect brake trouble, have your
brakes checked by a Hyundai dealer as
soon as possible. Driving your car with a
problem in either the brake electrical sys-
tem or brake hydraulic system is danger-
ous, and could result in a serious injury or
death.
Warning Light OperationThe parking brake/brake fluid level warning light
should come on when the parking brake is
applied and the ignition switch is turned to "ON"
or "START". After the engine is started, the light
should go out when the parking brake is re-
leased.
If the parking brake is not applied, the warning
light should come on when the ignition switch is
turned to "ON" or "START", then go out when
the engine starts. If the light comes on at any
other time, you should slow the vehicle and bring
it to a complete stop in a safe location off the
roadway.
The brake warning light indicates that the brake
fluid level in the brake master cylinder is low and
hydraulic brake fluid conforming to DOT 3 or
DOT 4 specifications should be added. After
B260J01A-AATCharging System Warning Light
The charging system warning light should come
on when the ignition is turned on, then go out
when the engine is running. If the light stays on
while the engine is running, there is a malfunc-
tion in the electrical charging system. If the light
comes on while you are driving, stop, turn off the
engine and check under the hood. First, make
certain the generator drive belt is in place. If it is,
check the tension of the belt. Do this as shown
on page 6-18 by pushing down on the center of
the belt. And then have the system checked by
your Hyundai dealer.
