WARNING:
o Even though your vehicle is equipped
with the occupant classification sys-
tem, never install a child restraint
system in the front passenger's seat.
A deploying air bag can forcefully
strike a child resulting in serious
injuries or death. Any child age 12 and
under should ride in the rear seat.
Children too large for child restraints
should use the available lap/shoulder
belts. No matter what type of crash,
children of all ages are safer when
restrained in the rear seat.
o If the "PASSENGER AIR BAG OFF"
indicator is illuminated when the front
passenger's seat is occupied 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 comfortably
extended and their feet on the floor),
have that person sit in the rear seat.
o Do not modify or replace the front
passenger seat. Don't place anything
on or attach anything such as a blanket
or after market seat heater to the
front passenger seat. This can
adversely affect the occupant
classification system.
o Do not sit on sharp objects such as tools
when occupying the front passenger
seat. This can adversely affect the occu-
pant classification system.
o Do not use accessory seat covers on
the front seats.
o Accident statistics show that children
are safer if they are restrained in the
rear, as opposed to the front seat. It is
recommended that child restraints be
secured in a rear seat, including an infant
riding in a rear-facing infant seat, a child
riding in a forward-facing child seat and
an older child riding in a booster seat.
o Air bags can only be used once – have
an authorized Hyundai dealer replace
the air bag immediately after
deployment.
o A smaller-stature adult who is not seated
correctly (for example: seat excessively
reclined, leaning on the center console,
or hips shifted forward in the seat) can
cause a condition where the advanced
frontal air bag 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 misclassified and
illumination of the "PASSENGER AIR
BAG OFF" indicator.
B990B05Y-AATSide Impact AirbagYour Hyundai is equipped with a side
impact airbag in each front seat. The
purpose of the airbag is to provide the
vehicle's driver and/or the front passenger
with additional protection than that offered
by the seat belt alone. The side impact
airbags are designed to deploy only during
certain side-impact collisions, depending
on the crash severity, angle, speed and
point of impact. The side impact airbags
are not designed to deploy in all side
impact situations.

Integrated HomeLink
® Wireless
Control System
The HomeLink
® Wireless Control System
provides a convenient way to replace up to
three hand-held radio-frequency (RF)
transmitters with a single built-in device.
This innovative feature will learn the radio
frequency codes of most current
transmitters to operate devices such as
gate operators, garage door openers, entry
door locks, security systems, even home
lighting. Both standard and rolling code-
equipped transmitters can be programmed
by following the outlined procedures.
Additional HomeLink
® information can be
found at: www.homelink.com or by calling
1-800-355-3515.
CAUTION:
Before programming HomeLink
® to a
garage door opener or gate operator,
make sure that people and objects are
out of the way of the device to prevent
potential harm or damage. Do not use
HomeLink
® with any garage door opener
that lacks the safety stop and reverse
features as required by U.S. federal
safety standards (this includes any
garage door opener model manufactured
before April 1, 1982). A garage door that
cannot detect an object - signaling the
door to stop and reverse - does not meet
current U.S. federal safety standards.
Using a garage door opener without these
features increases the risk of serious
injury or death.Programming HomeLink
®
NOTE:o When programming a garage door
opener, it is advised to park the vehicle
outside of the garage.
o It is recommended that a new battery
be placed in the hand-held transmitter
of the device being programmed to
HomeLink
® for quicker training and
accurate transmission of the radio-
frequency signal.
o Some vehicles may require the ignition
switch to be turned to the second (or
"accessories") position for program-
ming and/or operation of HomeLink.
o In the event that there are still pro-
gramming difficulties or questions
after following the programming steps
listed below, contact HomeLink
® at:
www.homelink.com or 1-800-355-
3515.
Retain the original transmitter of the RF
device you are programming for use in
other vehicles as well as for future
HomeLink
® programming. It is also
suggested that upon the sale of the vehicle,
the programmed HomeLink
® buttons be
erased for security purposes.

C090E02NF-GATo D (Drive):Use for normal driving. Bring the vehicle to
a complete stop before shifting the selector
to "D" position. The transaxle will automati-
cally shift through a five gear sequence.C090D02A-AATo N (Neutral):In the "N" position, the transaxle is in neutral,
which means that no gears are engaged.
The engine can be started with the shift
lever in "N" position, although this is not
recommended except if the engine stalls
while the car is moving.C090C01A-AATo R (Reverse):Use for backing up the vehicle. Bring the
car to a complete stop before shifting the
selector lever to "R" position.
CAUTION:
o In sports mode, the driver must
execute upward shifts in accordance
with prevailing road conditions, taking
care to keep the engine speed below
the red zone.
o For engine protection, upward shifts
are made automatically when the
engine rpm reaches the red zone.
o By rapidly moving the selector lever
backwards (-) twice it is possible to
skip one gear, i.e., 3rd to 1st, 4th to 2nd
or 5th to 3rd. Since sudden engine
braking and/or rapid acceleration can
cause a loss of traction, however,
downshifts must be made carefully in
accordance with the vehicle's speed.
!
C090F02L-GATSports ModeWhether the vehicle is stationary or in
motion, sports mode is selected by pushing
the selector lever from the "D" position into
the manual gate. To return to "D" range
operation, push the selector lever back
into the main gate.
In sports mode, moving the selector lever
backwards and forwards can make rapid
gearshifts simple. In contrast to a manual
transaxle, the sports mode allows gearshifts
with the accelerator pedal depressed.
UP (+) : Push the lever forward once to shift
up one gear.
DOWN (-) : Pull the lever backwards once
to shift down one gear.
SKIP : By rapidly moving the selector
forward or backward twice, it is possible to
skip one gear, i.e. 1st to 3rd or 3rd to 1st .

C090I03L-GAT
CAUTION:
o Shift into "R", "D" and "P" position
only when the vehicle has completely
stopped.
o Do not accelerate the engine in
reverse or any of the forward positions
with the brakes applied.
o Always apply the footbrake when shift-
ing from "P" or "N", to "R" or
"D"position.
o Do not use the "P" (Park) position in
place of the parking brake. Always
set the parking brake, shift the
transaxle into "P" (Park) position and
turn off the ignition when you leave the
vehicle, even momentarily. Never
leave the vehicle unattended while
the engine is running.
o When accelerating from a stop on a
steep hill, the vehicle may have a
tendency to roll backwards. Shifting
the shift lever into 2nd gear while in
Sport mode will help prevent the
vehicle from rolling backwards.
o Check the automatic transaxle fluid
level regularly, and add fluid as
necessary.
o See the maintenance schedule for
the proper fluid recommendation.
C090H01L-GATNOTE:o For smooth and safe operation,
depress the brake pedal when shifting
from "Neutral" position or "Park"
position to a forward or reverse gear.
o The ignition key must be in the "ON"
position and the brake pedal fully de-
pressed in order to move the shift
lever from the "P" (Park) position to
any of the other positions.
o It is always possible to shift from "R",
"N", or "D" position to "P" position.
The vehicle must be fully stopped to
avoid transaxle damage. o To maintain the required levels of ve-
hicle performance and safety, the sys-
tem may not execute certain
gearshifts when the selector lever is
operated.
o Before driving away from a stop on a
slippery road, push the selector lever
forward into the +(UP) position. This
causes the transaxle to shift into 2nd
gear which is better for smooth driv-
ing away on a slippery road. Push the
selector lever to the -(DOWN) side to
shift back to 1st gear.
C090J01NF-GATSHIFT LOCK RELEASEIf you cannot move the shift lever from the
"P" (Park) position to any other position
with the brake pedal fully depressed and
the ignition key in the "ON" position, remove
the cap on the console and with a thin
object such as a flat-head screwdriver,
push the shift lock release button down.
Then, with the brake pedal depressed,
move the shift lever to the desired position,
and then the shift lock release button will
automatically return to its original position
after shifting from the "P" (Park) position.
Then, reinstall the cap.
If you need to use the shift lock release, it
could mean your car is developing a
problem. Have the car checked by your
Hyundai dealer.

C190B01S-AATTrailer HitchesSelect the proper hitch and ball
combination, making sure that its location
is compatible with that of the trailer or
vehicle being towed.
Use a quality non-equalizing hitch which
distributes the tongue load uniformly
throughout the chassis.
The hitch should be bolted securely to the
car and installed by a qualified technician.
DO NOT USE A HITCH DESIGNED FOR
TEMPORARY INSTALLATION AND
NEVER USE ONE THAT ATTACHES
ONLY TO THE BUMPER.C190C01Y-AATTrailer BrakesIf your trailer is equipped with a braking
system, make sure it conforms to federal
and/or local regulations and that it is
properly installed and operating correctly.NOTE:If you tow a trailer or vehicle, your car will
require more frequent maintenance due
to the additional load. See Maintenance
Under Severe Usage Conditions" on
page 5-6.
TRAILER OR VEHICLE TOWING!
C190A01TG-AATIf you are considering towing with your car,
you should first check with your State's
Department of Motor Vehicles to determine
their legal requirements.
Since laws vary from State to State the
requirements for towing trailers, cars, or
other types of vehicles or apparatus may
differ. Ask your Hyundai dealer for further
details before towing.
CAUTION:
o Do not do any towing with your car
during its first 1,200 miles (2,000 km)
in order to allow the engine to properly
break in. Failure to heed this caution
may result in serious engine or
transaxle damage.
o When towing a trailer, be sure to con-
sult your Hyundai dealer for further
information on additional require-
ments such as a towing kit, etc.
USE OF LIGHTSC180A01A-AATCheck your lights regularly for correct op-
eration and always keep them clean. When
driving during the day in conditions of poor
visibility, it is helpful to drive with headlights
on low beam. This enables you to be seen,
as well as to see.
