B260M01A-AATLow Fuel Level Warning Light
The low fuel level warning light comes on when
the fuel tank is approaching empty. When it
comes on, you should add fuel as soon as
possible. Driving with the fuel level warning light
on or with the fuel level below "E" can cause the
engine to misfire and damage the catalytic
converter.
B260J01A-AATCharging System Warning Light
The charging system warning light should come
on when the ignition is turned on, then go out
when the engine is running. If the light stays on
while the engine is running, there is a malfunc-
tion in the electrical charging system. If the light
comes on while you are driving, stop, turn off
the engine and check under the hood. First,
make certain the generator drive belt is in
place. If it is, check the tension of the belt. Do
this as shown on page 6-13 by pushing down
on the center of the belt. And then have the
system checked by your Hyundai dealer.

and Chime
The door ajar warning light warns you that a
door is not completely closed and the chime
warns you that driver's side front door is not
completely closed.
NOTE:To remind you not to lock the key inside the
car, the warning light comes on whenever
the key is in the "LOCK" position and a door
is open. The warning chime only sounds
whenever the key is in the "LOCK" position
and the driver's side front door is open. The
chime sounds and the light remains on until
the key is removed from the ignition.
B260H01GK-AAT
Parking Brake/Brake Fluid
Level Warning Light
WARNING:
If you suspect brake trouble, have your
brakes checked by a Hyundai dealer as soon
as possible. Driving your car with a problem
in either the brake electrical system or brake
hydraulic system is dangerous, and could
result in a serious injury or death.
Warning Light Operation
The parking brake/brake fluid level warning light
should come on when the parking brake is ap-
plied and the ignition switch is turned to "ON" or
"START". After the engine is started, the light
should go out in three seconds.
If the parking brake is not applied, the warning
light should come on when the ignition switch is
turned to "ON" or "START", then go out in three
seconds. If the light comes on at any other time,
you should slow the vehicle and bring it to a
complete stop in a safe location off the roadway.
The brake warning light indicates that the brake
fluid level in the brake master cylinder is low and
hydraulic brake fluid conforming to DOT 3 or
DOT 4 specifications should be added. After
adding fluid, if no other trouble is found, the car
should be immediately and carefully driven to a
Hyundai dealer for inspection. If further trouble is
experienced, the vehicle should not be driven at
all but taken to a dealer by a professional towing
service or some other safe method.Your Hyundai is equipped with dual-diagonal
braking systems. This means you still have brak-
ing on two wheels even if one of the dual systems
should fail. With only one of the dual systems
working, more than normal pedal travel and
greater pedal pressure are required to stop the
car. Also, the car will not stop in as short a
distance with only half of the brake system work-
ing. If the brakes fail while you are driving, shift to
a lower gear for additional engine braking and
stop the car as soon as it is safe to do so.

To open the tail gate without using the key, pull
up the lid release lever.
To close, lower the tail gate, then press down
on it until it locks. To be sure the tail gate is
securely fastened, always try to pull it up again.
WARNING:The tail gate should always be kept com-
pletely closed while the vehicle is in motion.
If it is left open or ajar, poisonous exhaust
gases may enter the car resulting in serious
illness or death to the occupants. See addi-
tional warnings concerning exhaust gases
on page 2-1.

NOTE:If the fuel-filler lid will not open because ice
has formed around it, tap lightly or push on
the lid to break the ice and release the lid.
Do not pry on the lid. If necessary, spray
around the lid with an approved deicer fluid
(do not use radiator anti-freeze) or move the
vehicle to a warm place and allow the ice to
melt.
HGK124
WARNING:o The fuel cap must be tightened at least 3
clicks, otherwise " " light will illumi-
nate.
o Gasoline vapors are dangerous. Before
refueling, always stop the engine and
never allow sparks or open flames near
the filler area. If you need to replace the
filler cap, use a genuine Hyundai replace-
ment part.
o If you open the fuel filler cap during high
ambient temperatures, a slight "pressure
sound" may be heard. This is normal 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 MIL indicator
illuminating.
o Do not "TOP-OFF" after the first nozzle
shut off when refueling.

C140A01A-AAT
DRIVING FOR ECONOMY
You 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 unnec-
essarily. Avoid heavy traffic whenever pos-
sible. Always maintain a safe distance from
other vehicles so you can avoid unneces-
sary 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 high-
way, 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 ad-
dition, driving with your foot resting on the
brake pedal may cause the brakes to over-
heat, which reduces their effectiveness and
may lead to more serious consequences.
C300B01GK-GATTCS ON/OFF Mode
In the TCS ON mode, the indicator in the
instrument cluster will not be illuminated.
To switch the TCS OFF mode, press the TCS
switch . To switch the TCS mode, press the
TCS switch again. In the TCS OFF mode, the
SLIP control will be deactivated and the TCS-
OFF indicator in the instrument cluster will be
illuminated.
NOTE:1) Turn off the engine. Then restart the
engine, and the TCS mode will automati-
cally turn ON.
2) When the traction control is operating
properly, you can feel a slight pulsation
CAUTION:When the TCS indicator blinks, SLIP control
has been activated. It also means that the
road is slippery or your car is accelerating
excessively. In this situation, release foot
pressure from the accelerator pedal and
maintain moderate speed.
WARNING:Traction control is only a driving aid; all
normal precautions for driving in inclement
weather and on slippery road surfaces
should be observed.
C300D01GK-GAT
Indicator and Warning
The indicator should illuminate when the igni-
tion key is turned to ON or START but should
go out after three seconds.
If the indicator does not illuminate, or the TCS
indicator does not go out after 3 seconds, have
it checked by an authorized dealer.
Should there be any unusual conditions in the
device, TCS-OFF either illuminates or blinks as
a warning.
If TCS-OFF illuminates or blinks, pull your car
to a safe place and stop the engine.
Then, start the engine again to check if the
TCS-OFF indicator goes out.
If the indicator remains lit even after the engine
has been started, have your car checked by an
authorized Hyundai dealer.in the vehicle. This is only the effect of
brake control and indicates nothing un-
usual.
3) When the engine starts, a click is heard
from the engine compartment; however,
this is only the sound of traction control
being checked.
4) When moving out of the mud or fresh
snow, pressing the accelerator pedal may
not cause the engine speed to increase.
NOTE:1) When TCS-OFF illuminates or blinks, trac-
tion control is automatically deactivated
for safety.
2) This warning function is not provided
when the driver selects the TCS-OFF
mode.

DRIVING YOUR HYUNDAI
2- 11 o Remember, your Hyundai does not require
extended warm-up. As soon as the engine is
running smoothly, you can drive away. In
very cold weather, however, give your en-
gine 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 hap-
pens, shift to a lower gear. Over-revving is
racing the engine beyond its safe limit. This
can be avoided by shifting at the recom-
mended 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.
C150A01A-AAT
SMOOTH CORNERING
Avoid braking or gear changing in corners,
especially when roads are wet. Ideally, corners
should always be taken under gentle accelera-
tion. If you follow these suggestions, tire wear
will be held to a minimum.
C160A01A-AAT
WINTER DRIVING
The 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: o Take care of your tires. Keep them inflated
to the recommended pressure. Incorrect in-
flation, either too much or too little, results in
unnecessary tire wear. Check the tire pres-
sures at least once a month.
o Be sure that the wheels are aligned correct-
ly. Improper alignment can result from hitting
curbs or driving too fast over irregular sur-
faces. 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 impor-
tant 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 corro-
sion.
o Travel lightly. Don't carry unnecessary weight
in your car. Weight reduces fuel economy.
o Don't let the engine idle longer than neces-
sary. If you are waiting (and not in traffic),
turn off your engine and restart only when
you're ready to go.
C160C01A-AATUse High Quality Ethylene Glycol
Coolant
Your 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 cool-
ing system, lubricates the water pump and
prevents freezing. Be sure to replace or replen-
ish your coolant in accordance with the main-
C160B01A-AATSnowy or Icy Conditions
To 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 to the original equipment tires. Failure
to do so may adversely affect the safety and
handling of your car. Speeding, rapid accelera-
tion, 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 front and your vehicle. Also, apply
the brake gently. It should be noted that install-
ing 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.

DRIVING YOUR HYUNDAI

C190B01S-AAT
Trailer Hitches
Select 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 chas-
sis.
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.
C190A02S-AATTRAILER OR VEHICLE TOWING
If 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 re-
quirements for towing trailers, cars, 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.
C170A01A-AATHIGHER SPEED MOTORING
Pre-Trip Inspections
1. Tires:
Adjust the tire inflation pressures to specifica-
tion. Low tire inflation pressures will result in
overheating and possible failure of the tires.
Avoid using worn or damaged tires which may
result in reduced traction or tire failure.
NOTE:Never exceed the maximum tire inflation
pressure shown on the tires.
2. Fuel, engine coolant and engine oil: High
speed travel consumes 1.5 times more fuel
than urban motoring. Do not forget to check
both engine coolant and engine oil.
3. Drive belt:
A loose or damaged drive belt may result in
overheating of the engine.
C180A01A-AAT
USE OF LIGHTSCheck your lights regularly for correct operation
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.
C190C02S-AATTrailer Brakes
If 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 Un-
der Severe Usage Conditions" on page 5-5.
CAUTION:o Never connect a trailer brake system di-
rectly to the vehicle brake system.
o When towing a trailer on steep grades (in
excess of 12%) 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.

DRIVING YOUR HYUNDAI
2- 15 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, occasionally check 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, downshift the
transaxle to a lower gear and reduce speed
to reduce chances of engine overloading
and/or overheating.
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 overheat. Use the parking brake
or footbrake.
NOTE:When towing check transaxle fluid more
frequently.
C190F01S-AATTrailer or Vehicle Towing Tips
1. 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 nor-
mal conditions.
4. To maintain engine braking efficiency and
electrical charging performance, do not use
fifth gear (manual transaxle) or overdrive
(automatic 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.
8. When parking your car and trailer, especial-
ly 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.
CAUTION:If overheating should occur when towing,
(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 en-
gine at a higher speed.
