Integrated HomeLink
® Wireless Control
System
The HomeLink
® Wireless Control System pro-
vides 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 ga-
rage 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 manufac-
tured 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 fea-
tures 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 ac-
curate transmission of the radio-fre-
quency 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 program-
ming difficulties or questions after fol-
lowing 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.

WARNING:
o If you open the fuel filler cap during high
ambient temperatures, a slight "pres-
sure sound" may be heard. This is nor-
mal and not a cause for concern.
Whenever you open the fuel filler cap,
turn it slowly.
o Make sure the fuel filler cap is replaced
and securely seated after fueling. Failure
to replace or fully seat the fuel filler cap
will result in fuel vapors escaping into
the atmosphere and the check engine
" " indicator illuminating.
o Do not "TOP-OFF" after the first nozzle
shut off when refueling.
o Automotive fuels are flammable/explo-
sive materials. When refueling, please
note the following guidelines carefully.
- Before touching the fuel nozzle or fuel
filler cap, have one's hands in contact
with metal parts away from the filler
neck to discharge static electricity.

C090E01NF-GATo D (Drive):Use for normal driving. The transaxle will auto-
matically shift through a four/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 pre-
vailing 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 back-
wards and forwards can make rapid gearshifts
simple. In contrast to a manual transaxle, the
sports mode allows gearshifts with the accel-
erator 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 .
C090F02NF
NOTE:o In sports mode, only the four/five for-
ward gears can be selected. To reverse or
park the vehicle, move the selector lever
to the "R" or "P" position as required.
o In sports mode, downward shifts are
made automatically when the vehicle
slows down. When the vehicle stops, 1st
gear is automatically selected.

CAUTION:
o Shift into "R" 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 ten-
dency 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 "Neu-
tral" 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 driving
away on a slippery road. Push the selec-
tor lever to the -(DOWN) side to shift
back to 1st gear.
C090J01NF-GATSHIFT LOCK RELEASE (If Installed)If 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 de-
pressed, 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 distrib-
utes 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!
C190A01S-AATIf you are considering towing with your car, you
should first check with your State's Department
of Motor Vehicles to determine their legal re-
quirements.
Since laws vary from State to State the require-
ments for towing trailers, cars, or other types of
vehicles or apparatus may differ. Ask your
Hyundai dealer for further details before towing.
CAUTION:
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. Fail-
ure to heed this caution may result in seri-
ous engine or transaxle damage.
USE OF LIGHTSC180A01A-AATCheck your lights regularly for correct opera-
tion 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.

C190F01Y-GATTrailer or Vehicle Towing Tips1. Before towing, check hitch and safety chain
connections as well as proper operation of
the trailer running lights, brake lights, and
turn signals.
2. Always drive your vehicle at a moderate
speed. (Less than 60 mph)
3. Trailer towing requires more fuel than normal
conditions.
4. To maintain engine braking efficiency and
electrical charging performance, do not tow
a trailer with the transaxle in fifth gear (manual
transaxle).
5. Always secure items in the trailer to prevent
load shift while driving.
6. Check the condition and air pressure of all
tires on the trailer and your car. Low tire
pressure can seriously affect the handling.
Also check the spare tire.
7. The vehicle/trailer combination is more af-
fected by crosswind and buffeting.
When being passed by a large vehicle, keep
a constant speed and steer straight ahead.
If there is too much wind buffeting, slow down
to get out of the other vehicle's air turbulence.

CAUTION:
The following specifications are recom-
mended when towing a trailer. The loaded
trailer weight cannot safely exceed the val-
ues in the chart below.
WARNING:
o Improperly loading your vehicle and
trailer can seriously affect its steering
and braking performance causing a
crash which could cause serious injury
or death.
o Towing a trailer affects vehicle handling
and braking.
o Drive more slowly when towing a trailer
and allow more distance when braking.
o Be careful when driving in slippery and
windy conditions.
o Be careful when turning and while driv-
ing up and down hills. 3. The front or rear axle weight must not
exceed the Gross Axle Weight Rating
(GAWR) shown on the vehicle identifi-
cation plate (see page 8-2). It is possible
that your towing package does not ex-
ceed the GVWR but exceeds the GAWR.
Improper trailer loading and/or too much
luggage in the trunk can overload the
rear axle. Redistribute the load and check
the axle weight again.
