C310D01NF-AATIndicators and WarningThe indicators should illuminate when the igni-
tion key is turned to ON or START but should
go out after three seconds.
If the indicators do not illuminate, or the ESC or
ESC-OFF indicator does not go out after 3
seconds, have the vehicle checked by an
authorized dealer.
Should there be any unusual operation of the
device while driving, the ESC-OFF indicator
illuminates as a warning.
If the ESC-OFF indicator illuminates, drive your
car to a safe place and stop the engine.
Then, start the engine again to check if the ESC-
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.
C310B01NF-AATESC ON/OFF ModeWhen the ESC is operating, the ESC indicator
in the instrument cluster will blink.
If you turn the system off by pressing the ESC
switch, the ESC-OFF indicator will come on and
stay on. In the ESC-OFF mode, the stability
control will be deactivated. Adjust your driving
accordingly. To turn the system back on, press
the switch again. The ESC-OFF indicator should
go off.NOTE:The ESC mode will automatically be turned
ON after the engine is turned off and re-
started.

o Remember, your Hyundai does not require
extended warm-up. After the engine 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 result-
ing 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 Be sure that the wheels are aligned cor-
rectly. 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 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.
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 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
addition, 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.
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.

8. When parking your car and trailer, especially
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, downshift the
transaxle to a lower gear and reduce speed
to reduce chances of engine overloading
and/or overheating.
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 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 overheat. Use the parking brake
or footbrake.NOTE:When towing check transaxle fluid more
frequently.

36WHAT TO DO IN AN EMERGENCY
!
Low tire pressure telltale
When the tire pressure monitoring sys-
tem warning telltale is illuminated, one
or more of your tires is significantly
under-inflated.
Immediately reduce your speed, avoid
hard cornering and anticipate increased
stopping distances. You should stop
and check your tires as soon as pos-
sible. Inflate the tires to the proper
pressure as indicated on the vehicle’s
placard or tire inflation pressure label
located on the driver’s side center pillar
outer panel. If you cannot reach a ser-
vice station or if the tire cannot hold the
newly added air, replace the low pres-
sure tire with the temporary spare tire.
Then the TPMS malfunction indicator
may turn on and the Low Tire Pressure
telltale may turn off after restarting and
about 20 minutes of continuous driving
before you have the low-pressure tire
repaired and replaced on the vehicle.CAUTION:
In winter or cold weather, the low tire
pressure telltale may be illuminated
if the tire pressure was adjusted to
the recommended tire inflation pres-
sure in warm weather. It does not
mean your TPMS is malfunctioning
because the decreased temperature
leads to a proportional lowering of
tire pressure.
When you drive your vehicle from a
warm area to a cold area or from a
cold area to a warm area, or the
outside temperature is greatly higher
or lower, you should check the tire
inflation pressure and adjust the tires
to the recommended tire inflation
pressure.WARNING:
Significantly low tire pressure makes
the vehicle unstable and can contrib-
ute to loss of vehicle control and
increased braking distances.
Continued driving on low pressure
tires will cause the tires to overheat
and fail.
TPMS (Tire pressure monitoring
system) malfunction telltale
The TPMS malfunction telltale turns on
and stays on when there is a problem
with the Tire Pressure Monitoring Sys-
tem. If the system is able to correctly
detect an under-inflation warning at the
same time as system failure then it will
illuminate both the TPMS malfunction
and the low tire pressure telltale e.g. if
Front Left sensor fails, the TPMS mal-
function telltale turns, but if Front Right,
Rear Left, or Rear Right tire is under-
inflated, the low tire pressure telltale

3. Slide underneath the car and loosen the
drain plug by turning it counterclockwise with
a wrench of the proper size. Be sure that a
drain pan is in position to catch the oil as it
drains out, then remove the drain plug.
4. When the oil has stopped draining, replace
the drain plug using a new gasket and re-
tighten by turning it clockwise.

(3.3L) The engine oil and filter should be changed at
those intervals specified in the maintenance
schedule in Section 5. If the car is being driven
in severe conditions, more frequent oil and filter
changes are required.
The procedure for changing the oil and filter is
as follows:
1. Park the car on level ground and set the
parking brake. Start the engine and let it
warm up until the needle on the coolant
temperature gauge moves above the lowest
mark. Turn the engine off and place the gear
selector lever in "P" (automatic) or reverse
gear (manual transaxle).
2. Open the hood and remove the engine oil
filler cap.
NOTE:Loosen the oil filter cap by turning it coun-
terclockwise to drain well the oil in the oil
filter (3.3L only).
WARNING:
Be very careful when draining the engine oil
as it may be hot enough to burn you!

3. Be sure your drain receptacle is in place.
Open the drain cock on the radiator. Allow all
the engine coolant to drain from the cooling
system, and then securely close the drain
cock.
4. Check Section 9 for the capacity of the
cooling system in your car. Then, following
the manufacturer's directions on the engine
coolant container, add the appropriate quan-
tity of coolant to the radiator.
5. Slowly fill the radiator with the proper coolant
mixture (see the "Recommended Engine
Coolant in previous page) until the fluid level
stays up in the radiator neck. And pump the
radiator hose in order to bleed the air.
HNF5008
2. Wrap a thick cloth around the radiator cap
and slowly turn the radiator cap counter-
clockwise without pressing down on it, until
it stops. This relieves any pressure remain-
ing in the cooling system. When you are sure
that all the pressure has been released,
remove the radiator cap by pushing down
and turning counterclockwise.

6. Run the engine at idle until the coolant circu-
lates. If the cooling fan operates and the
coolant starts to circulate, add the coolant to
the reservoir.
7. To bleed the air in the cooling system, repeat
procedure 6 until the cooling fan operates
3~5 times.
8. Replace the radiator cap and turn it until
tightly installed. And then, add coolant to the
reservoir until the level is between "L" and
"F".
9. Stop the engine and check the coolant level
when the engine is cool. The level of the
coolant should be the "L" and "F" lines on the
reservoir. If the level is below the "L" line,
repeat the procedure 4~8 until the level
between "L" and "F".

G240A01A-AATPOWER STEERING HOSESIt is suggested that you check the power steer-
ing hose connections for fluid leakage at those
intervals specified in the vehicle maintenance
schedule in Section 5.
The power steering hoses should be replaced
if there is severe surface cracking, pulling,
scuffing or worn spots. Deterioration of the hose
could cause premature failure.
POWER STEERING FLUID LEVELG230A01NF-AAT
to make certain that the power steering fluid
level is between the "MAX" and "MIN" level
markings on the fluid reservoir.NOTE:Grinding noise from the power steering
pump may be heard immediately after the
engine is started in extremely cold condi-
tions (below - 4°F). If the noise stops during
warm up, there is no abnormal function in
the system. It is due to a power steering
fluid characteristic in extremely cold condi-
tions.
Recommended Fluid
Use PSF-4 type fluidNOTE:Do not start the engine when the power
