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 .
ONF058007
NOTE:o In sports mode, only the five forward
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", "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.
C090J02NF-GATSHIFT LOCK RELEASEIf the shift lever cannot be moved from the
P (Park) position with the brake pedal
depressed, continue depressing the brake,
then do the following:
1. Carefully remove the cap covering the
shift-lock override access hole.
2. Insert a screwdriver (or key) into the
access hole and press down on the
screwdriver (or key).
3. Move the shift lever.
4. Have your vehicle inspected by an au-
thorized Hyundai dealer immediately.

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.

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
affected 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
values in the chart below.
WARNING:
o Improperly loading your vehicle and
trailer can seriously affect its steer-
ing and braking performance causing
a crash which could cause serious
injury or death.
o Towing a trailer affects vehicle han-
dling 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
driving up and down hills. 3. The front or rear axle weight must not
exceed the Gross Axle Weight Rating
(GAWR) shown on the vehicle identi-
fication plate (see page 8-2). It is
possible that your towing package
does not exceed 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.

8. When parking your car and trailer, es-
pecially on a hill, be sure to follow all
the normal precautions. Turn your front
wheel into the curb, set the parking
brake firmly, and put the transaxle in 1st
or Reverse (manual) or Park (automatic).
In addition, place wheel chocks at each
of the trailer's tires.
9. If the trailer has electric brakes, start
your vehicle and trailer moving, and
then apply the trailer brake controller by
hand to be sure the brakes are working.
This lets you check your electrical
connection at the same time.
10. During your trip, check occasionally to
be sure that the load is secure, and that
the lights and any trailer brakes are still
working.
11. Avoid jerky starts, sudden acceleration
or sudden stops.
12. Avoid sharp turns and rapid lane
changes.
13. Avoid holding the brake pedal down
too long or too frequently. This could
cause the brakes to overheat, resulting
in reduced braking efficiency.
14. When going down a hill, shift into a
lower gear and use the engine braking
effect.
When ascending a long grade, down-
shift the transaxle to a lower gear and
reduce speed to reduce chances of
engine overloading and/or overheat-
ing.
CAUTION:
If overheating should occur when tow-
ing, (the temperature gauge reads near
red zone), taking the following action
may reduce or eliminate the problem.
1. Turn off the air conditioner.
2. Reduce highway speed.
3. Select a lower gear when going uphill.
4. While in stop and go traffic, place the
gear selector in park or neutral and
idle the engine at a higher speed.
!
15. If you have to stop while going uphill,
do not hold the vehicle in place by
pressing on the accelerator. This can
cause the automatic transaxle to over-
heat. Use the parking brake or
footbrake.NOTE:When towing check transaxle fluid more
frequently.

load your vehicle the right way.
The label will help you decide how much
cargo and installed equipment your
vehicle can carry.
If you carry items inside your vehicle –
like suitcases, tools, packages, or any-
thing else – they move as fast as the
vehicle goes. If you have to stop or turn
quickly, or if there is a crash, the items
will keep going and can cause an injury
if they strike the driver or a passenger.
!
WARNING:
o Overloading your vehicle can
cause heat buildup in your
vehicle's tires and possible tire
failure that could lead to a crash.
o Overloading your vehicle can
cause increased stopping dis-
tances that could lead to a crash.
o A crash resulting from poor han-
dling vehicle damage, tire failure,
or increased stopping distances
could result in serious injury or
death.
