BREAKING IN YOUR NEW HYUNDAI
B010F01A-AATOperation in Foreign CountriesIf you are going to drive your Hyundai in another
country, be sure to:
o Observe all regulations regarding registra-
tion and insurance.
o Determine that acceptable fuel is available.B010E01A-AATGasolines for Cleaner AirTo help contribute to cleaner air, Hyundai rec-
ommends that you use gasolines treated with
detergent additives, which help prevent deposit
formation in the engine. These gasolines will
help the engine run cleaner and enhance per-
formance of the Emission Control System.
B020A01S-AATDuring 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).
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.
B030A01NF-GATFor 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, glove box 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 knobs of
the rear seatback lock and the trunk lid lock
are switched to the "LOCK" position.

WARNING:
- When using a portable fuel container,
be sure to place the container on the
ground while refueling. Static electric-
ity discharge from the container can
ignite fuel vapors causing a fire. While
starting refueling, contact should be
maintained until the filling is complete.
- Do not use cellular phones around a
gas station. The electric current or elec-
tronic interference from cellular phones
can ignite fuel vapors causing a fire.
- When refueling, always turn the engine
off. Sparks by engine compartment
electrical equipment can ignite fuel
vapors causing a fire. After refueling,
check to make sure the fuel filler cap is
securely closed, and then start the
engine.
- Do not smoke or try to light cigarettes
around a gas station. Automotive fuels
are flammable.
B560B01L-GATManual Fuel Filler Lid ReleaseIf the fuel filler lid cannot be opened using the
remote opener, a manual opener handle is
located inside the trunk on the left side. Open the
fuel filler lid by pulling on this handle as shown
in the illustration.

DRIVING YOUR HYUNDAI

!
ANTI-LOCK BRAKE SYSTEM (ABS)C120A01NF-AATThe Anti-Lock Brake System (ABS) is designed
to prevent wheel lock-up during sudden braking
or on hazardous road surfaces. The ABS con-
trol module monitors the wheel speed and con-
trols the pressure applied to each brake. Thus,
in emergency situations or on slick roads, ABS
will increase vehicle control during braking.NOTE:o A click sound may be heard in the engine
compartment when the vehicle begins
to move after the engine is started. These
conditions are normal and indicate that
the anti-lock brake system (Electronic
Stability Control) is functioning prop-
erly.
o During ABS (ESC) operation, a pulsation
may be felt in the brake pedal when the
brakes are applied. Also, a noise may be
heard in the engine compartment while
braking. These conditions are normal
and indicate that the anti-lock brake
system (Electronic Stability Control Sys-
tem) is functioning properly.
Setting the driver's position1) Be sure the parking brake is engaged.
2) Move the accelerator and brake pedals to
the front most position by pushing the " "
portion of the switch.
3) Adjust the seat position and the steering
wheel angle properly.
4) Move the pedals toward you until you can
fully depress the brake pedal by pushing the
" " portion of the switch.
5) Depress the pedals a few times to get used
to the feel after adjusting.
WARNING:
o Adjust the pedals after parking the ve-
hicle on level ground. Never attempt to
adjust the pedals while the vehicle is
moving.
o Never adjust the pedals with your foot
on the accelerator pedal as this may
result in increasing the engine speed
and acceleration.
o Make sure that you can fully depress the
brake pedal before driving. Otherwise,
you may not be able to hold down the
brake pedal firmly in an emergency stop.
POWER ADJUSTABLE PEDALSC100A01NF-AAT(With Automatic Transaxle) (If Installed)To adjust the position of the accelerator and
brake pedals, turn the ignition key to the "ON"
position with the selector lever in the "P" position
and push the switch.
If you push the " " portion of the switch, the
pedals move rearward.
If you push the " " portion of the switch, the
pedals move forward.

DO-IT-YOURSELF MAINTENANCE

Drive belts should be checked periodically for
proper tension. At the same time, belts should
be examined for cracks, wear, fraying or other
evidence of deterioration and replaced if neces-
sary.
When a new belt is replaced, the belt should be
located within the pulley of flat idler.
Belt routing should also be checked to be sure
there is no interference between the belts and
other parts of the engine.
NOTE:Drive belt tension is adjusted automatically
by the auto tensioner.
CHECKING AND REPLACING
FUSESG200A01A-AATReplacing a Fusible LinkA fusible link will melt if the electrical circuits from
the battery are ever overloaded, thus prevent-
ing damage to the entire wiring harness. (This
could be caused by a short in the system
drawing too much current.) If this ever happens,
have a Hyundai dealer determine the cause,
repair the system and replace the fusible link.
The fusible links are located in a relay box in the
engine compartment for easy inspection.
HNF4004
!
CAUTION:
When replacing a fusible link, never use
anything but a new fusible link with the
same or lower amperage rating. Never use
a piece of wire or a higher-rated fusible link.
This could result in serious damage and
create a fire hazard.
