NOTE:o In sports mode, downward shifts are
made automatically when the vehicle
slows down. When the vehicle stops,
1st gear is automatically selected.
o To maintain the required levels of ve-
hicle performance and safety, the sys-
tem may not execute certain gear-
shifts when the selector lever is oper-
ated.
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.
!
C090I04L-GAT
CAUTION:
o Shift into "R", "D" and "P" position
only when the vehicle has completely
stopped.
o Do not accelerate the engine in re-
verse or any of the forward positions
with the brakes applied.
o Always apply the footbrake when
shifting 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 ve-
hicle from rolling backwards.
o Check the automatic transaxle fluid
level regularly, and add fluid as nec-
essary.
o See the maintenance schedule for
the proper fluid recommendation.
CAUTION:
o In sports mode, the driver must ex-
ecute upward shifts in accordance
with prevailing road conditions, tak-
ing 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 Since sudden engine braking and/or
rapid acceleration can cause a loss of
traction, downshifts must be made
carefully in accordance with the
vehicle's speed.

C190B01S-AATTrailer HitchesSelect the proper hitch and ball combina-
tion, making sure that its location is com-
patible 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.
TRAILER OR VEHICLE TOW-
ING!
C190A01TG-AATIf you are considering towing with your car,
you should first check with your State's
Department of Motor Vehicles to deter-
mine 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.
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 prop-
erly 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.
CAUTION:
o Never connect a trailer brake system
directly to the vehicle brake system.
o When towing a trailer on steep grades
(in excess of 6%) pay close attention
to the engine coolant temperature
gauge to ensure the engine does not
overheat. If the needle of the coolant
temperature gauge moves across the
dial towards "H" (HOT), pull over and
stop as soon as it is safe to do so, and
allow the engine to idle until it cools
down. You may proceed once the
engine has cooled sufficiently.

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 brak-
ing.
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 pos-
sible 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. Redistrib-
ute the load and check the axle weight
again.
C190F01TG-AATTrailer 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 moder-
ate 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
engaged in overdrive gear.
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.

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
Park. 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 elec-
trical 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 accelera-
tion 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.

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.NOTE:
o Overloading your vehicle may
cause damage. Repairs would not
be covered by your warranty. Do
not overload your vehicle.
o Using heavier suspension com-
ponents to get added durability
might not change your weight rat-
ings. Ask your dealer to help you
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:
Items you carry inside your vehicle
can strike and injure people in a
sudden stop or turn, or in a crash.
o Put things in the cargo area of
your vehicle. Try to spread the
weight evenly.
o Never stack items, like suitcases,
inside the vehicle above the tops
of the seats.
o Do not leave an unsecured child
restraint in your vehicle.
o When you carry something inside
the vehicle, secure it.
o Do not drive with a seat folded
down unless necessary.

a straight line. Move cautiously off the
road to a safe place.
2. Turn on your emergency flashers.
3. Try to start the engine again. If your
vehicle will not start, contact a Hyundai
dealer or seek other qualified assis-
tance.
WARNING:
If the engine will not start, do not push or
pull the car to start it. This could result in
a collision or cause other damage. In
addition, push or pull starting may cause
the catalytic converter to be overloaded
and create a fire hazard.

D060J02O-AATAfter Changing Wheels
If you have a tire gauge, remove the
valve cap and check the air pressure. If
the pressure is lower than recom-
mended, drive slowly to the nearest
service station and inflate to the correct
pressure. If it is too high, adjust it until
it is correct. Then position the wrench as shown in
the drawing and tighten the wheel nuts.
Be sure the socket is seated com-
pletely over the nut. Do not stand on the
wrench handle or use an extension pipe
over the wrench handle.
Go around the wheel tightening every
other nut until they are all tight. Then
double-check each nut for tightness.
After changing wheels, have a techni-
cian tighten the wheel nuts to their
proper torque as soon as possible.Wheel nut tightening torque:
65-80 lb.ft (900-1,100 kg.cm)
D060I02TG-A
D060J01TG-A
Always reinstall the valve cap after
checking or adjusting tire pressure. If
the cap is not replaced, air may leak
from the tire. If you lose a valve cap,
buy another and install it as soon as
possible.
After you have changed wheels, al-
ways secure the flat tire in its place and
return the jack and tools to their proper
storage locations.

F060D01A-AATo Fuel Lines, Fuel Hoses and Con-
nectionsCheck the fuel lines, fuel hoses and con-
nections for leakage and damage. Have a
trained technician replace any damaged
or leaking parts immediately.F060B01NF-GATo Drive BeltsInspect all drive belts for evidence of cuts,
cracks, excessive wear or oil saturation
and replace if necessary. Drive belts should
be checked periodically for proper ten-
sion.
F060M01A-AATo Engine Oil and FilterThe engine oil and filter should be changed
at the intervals specified in the mainte-
nance schedule. If the car is being driven
in severe conditions, more frequent oil and
filter changes are required.F060C01A-AATo Fuel FilterA clogged filter can limit the speed at which
the vehicle may be driven, damage the
emission system and cause hard starting.
If an excessive amount of foreign matter
accumulates in the fuel tank, the filter may
require replacement more frequently.
After installing a new filter, run the engine
for several minutes, and check for leaks at
the connections. Fuel filters should be
installed by trained technicians.
F060F01A-AATo Vacuum, Crankcase Ventilation
HosesInspect the surface of hoses for evidence
of heat and/or mechanical damage. Hard
and brittle rubber, cracking, tears, cuts,
abrasions, and excessive swelling indi-
cate deterioration. Particular attention
should be paid to examine those hose
surfaces nearest to high heat sources,
such as the exhaust manifold.
Inspect the hose routing to assure that the
hoses do not come in contact with any heat
source, sharp edges or moving compo-
nent which might cause heat damage or
mechanical wear. Inspect all hose con-
nections, such as clamps and couplings,
to make sure they are secure, and that no
leaks are present. Hoses should be re-
placed immediately if there is any evi-
dence of deterioration or damage.
