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.

o Travel lightly. Don't carry unnecessary
weight in your car. Weight reduces fuel
economy.
o Don't let the engine idle longer than
necessary. If you are waiting (and not in
traffic), turn off your engine and restart
only when you're ready to go.
o Remember, your Hyundai does not re-
quire extended warm-up. After the en-
gine has started, allow the engine to run
for 10 to 20 seconds prior to placing the
vehicle in gear. In very cold weather,
however, give your engine a slightly
longer warm-up period.
o Don't "lug" or "over-rev" the engine.
Lugging is driving too slowly in too high
a gear resulting in the engine bucking.
If this happens, shift to a lower gear.
Over-revving is racing the engine
beyond its safe limit. This can be avoided
by shifting at the recommended speeds.
o Use your air conditioning sparingly. The
air conditioning system is operated by
engine power so your fuel economy is
reduced when you use it. o Take care of your tires. Keep them
inflated to the recommended pressure.
Incorrect inflation, either too much or
too little, results in unnecessary tire
wear. Check the tire pressures at least
once a month.
o Be sure that the wheels are aligned
correctly. Improper alignment can result
from hitting curbs or driving too fast over
irregular surfaces. Poor alignment
causes faster tire wear and may also
result in other problems as well as
greater fuel consumption.
o Keep your car in good condition. For
better fuel economy and reduced
maintenance costs, maintain your car
in accordance with the maintenance
schedule in Section 5. If you drive your
car in severe conditions, more frequent
maintenance is required (see Section 5
for details).
o Keep your car clean. For maximum
service, your Hyundai should be kept
clean and free of corrosive materials. It
is especially important that mud, dirt,
ice, etc. not be allowed to accumulate
on the underside of the car. This extra
weight can result in increased fuel
consumption and also contribute to cor-
rosion.
DRIVING FOR ECONOMYC140A02A-AATYou can save fuel and get more miles from
your car if you follow these suggestions:
o Drive smoothly. Accelerate at a
moderate rate. Don't make "jack-rabbit"
starts or full-throttle shifts and maintain
a steady cruising speed. Don't race
between stoplights. Try to adjust your
speed to that of the other traffic so you
don't have to change speeds unneces-
sarily. Avoid heavy traffic whenever pos-
sible. Always maintain a safe distance
from other vehicles so you can avoid
unnecessary braking. This also reduces
brake wear.
o Drive at a moderate speed. The faster
you drive, the more fuel your car uses.
Driving at a moderate speed, especially
on the highway, is one of the most
effective ways to reduce fuel
consumption.
o Don't "ride" the brake or clutch pedal.
This can increase fuel consumption and
also increase wear on these
components. In addition, driving with
your foot resting on the brake pedal may
cause the brakes to overheat, which
reduces their effectiveness and may
lead to more serious consequences.

SMOOTH CORNERINGC150A01A-AATAvoid braking or gear changing in corners,
especially when roads are wet. Ideally,
corners should always be taken under
gentle acceleration. If you follow these
suggestions, tire wear will be held to a
minimum.
C160A01A-AATThe more severe weather conditions of
winter result in greater wear and other
problems. To minimize the problems of
winter driving, you should follow these
suggestions:C160B01A-AATSnowy or Icy ConditionsTo drive your vehicle in deep snow, it may
be necessary to use snow tires or to install
tire chains on your tires. If snow tires are
needed, it is necessary to select tires
equivalent in size and type of the original
equipment tires. Failure to do so may
adversely affect the safety and handling of
your car. Furthermore, speeding, rapid
acceleration, sudden brake applications,
and sharp turns are potentially very
hazardous practices.
During deceleration, use engine braking to
the fullest extent. Sudden brake applications
on snowy or icy roads may cause skids to
occur. You need to keep sufficient distance
between the vehicle in operation in front
and your vehicle. Also, apply the brake
gently. It should be noted that installing tire
chains on the tire will provide a greater
driving force, but will not prevent side skids.NOTE:Tire chains are not legal in all states.
Check state laws before fitting tire
chains.WINTER DRIVING
C160D01A-AATCheck Battery and CablesWinter puts additional burdens on the
battery system. Visually inspect the battery
and cables as described in Section 6. The
level of charge in your battery can be
checked by your Hyundai dealer or a
service station.C160C01A-AATUse High Quality Ethylene Glycol
CoolantYour Hyundai is delivered with high quality
ethylene glycol coolant in the cooling
system. It is the only type of coolant that
should be used because it helps prevent
corrosion in the cooling system, lubricates
the water pump and prevents freezing. Be
sure to replace or replenish your coolant in
accordance with the maintenance
schedule in Section 5. Before winter, have
your coolant tested to assure that its
freezing point is sufficient for the
temperatures anticipated during the winter.

VEHICLE MAINTENANCE REQUIREMENTS2
F010C01A-AATSpecified Scheduled ProceduresThese are the procedures such as
inspections, adjustments and
replacements that are listed in the
maintenance charts starting on page 5-4.
These procedures must be performed at
the intervals shown in the maintenance
schedule to assure that your warranty
remains in effect. Although it is strongly
recommended that they be performed by
the trained technicians at your Hyundai
dealer, these procedures may be per-
formed at any qualified service facility.
It is suggested that genuine Hyundai
service parts be used for any required
repairs or replacements. Other parts of
equivalent quality such as engine oil,
engine coolant, manual or auto transaxle
oil, brake fluid and so on which are not
supplied by Hyundai Motor Company or its
distributor may be used without affecting
your warranty coverage but you should
always be sure these are equivalent to the
quality of the original Hyundai parts. Your
Owner's Handbook provides further
information about your warranty coverage.
F010A01A-AATService RequirementsTo ensure that you receive the greatest
number of miles of satisfying operation
from your Hyundai, certain maintenance
procedures must be performed. Although
careful design and engineering have
reduced these to a minimum, those that
are required are of the utmost importance.
It is your responsibility to have these main-
tenance procedures performed to comply
with the terms of the warranties covering
your new Hyundai. The Owner's Handbook
supplied with your new vehicle provides
further information about these warranties.
F010B01A-AATMaintenance RequirementsThe maintenance required for your
Hyundai can be divided into three main
areas:
o Specified scheduled procedures
o General checks
o Do-it-yourself maintenance

SCHEDULED MAINTENANCE
REQUIREMENTSF020A02Y-AATo Inspection should be performed any
time a malfunction is experienced or
suspected.
o Receipts for all emission control system
services should be retained to
demonstrate compliance with
conditions of the emissions system
warranty.
o After 120 months or 150,000 miles
(240,000 km), continue to follow the
prescribed maintenance intervals.
o For severe usage maintenance require-
ments, see page 5-6 of this section.
F010D02A-AATGeneral ChecksThese are the regular checks you should
perform when you drive your Hyundai or
you fill the fuel tank. A list of these items will
be found on page 6-4.F010E01A-AATDo-It-Yourself MaintenanceIf you are mechanically inclined, own a few
tools that are required and want to take the
time to do so, you can inspect and service
a number of items. For more information
about doing it yourself, see Section 6.
F010F01A-AATA Few Tipso Whenever you have your Hyundai
serviced, keep copies of the service
records in your glove box. This will help
ensure that you can document that the
required procedures have been
performed to keep your warranties in
effect. This is especially important when
service is not performed by an authorized
Hyundai dealer.
o If you choose to do your own
maintenance and repairs, you may find
it helpful to have an official Hyundai
Shop Manual. A copy of this publication
may be purchased at your Hyundai
dealer's parts department.

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 tension.
F060M01A-AATo Engine Oil and FilterThe engine oil and filter should be changed
at the intervals specified in the
maintenance 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 indicate
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 component
which might cause heat damage or
mechanical wear. Inspect all hose
connections, such as clamps and
couplings, to make sure they are secure,
and that no leaks are present. Hoses should
be replaced immediately if there is any
evidence of deterioration or damage.
