Features of your vehicle
Auto defogging system (if equipped)
Auto defogging reduces the probabil-
ity of fogging up the inside of the
windshield by automatically sensing
the moisture of inside the windshield.
The auto defogging system operates
when the heater or air conditioning is
on. This indicator illuminates
when the auto defogging
system senses the mois-
ture of inside the wind-
shield and operates.
If more moisture is in the vehicle, the
automated steps operate as follows:
If auto defogging does not defog the
window at step 1, outside air posi-
tion, step 2, blowing air toward the
windshield occurs.
Step 1 : Outside air position
Step 2 : Blowing air toward the wind- shield
Step 3 : Increasing air flow toward the windshield
Step 4 : Operating the air condition- ing
Step 5 : Maxim izing the air condi-
tioning
The auto defogging system is auto-
matically activated when the condi-
tions are met. However, if you would
like to cancel the auto defogging sys-
tem, press the front defroster button
4 times within 2 seconds while press-
ing the AUTO button. The indicator of the front defroster
button will blink 3 times to notify you
that the system is cancelled. To use
the auto defogging system again, fol-
low the procedures mentioned
above.
If the battery has been disconnected
or discharged, it resets to the auto
defogging status.
✽ ✽
NOTICE
When the air conditioning is turned
on and the outside air position is
selected by the auto defogging sys-
tem, if you try to turn off the air con-
ditioning and select the recirculated
air position, the indicator will blink
3 times and the air conditioning will
not be turned off and recirculated
air position will not be selected.
CAUTION
Do not remove the sensor cover
located on the upper end of thedriver side windshield glass.Damage to system parts couldoccur and may not be coveredby your vehicle warranty.

Driving your vehicle

Remember, your vehicle 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.
Don't "lug" or "over-rev" the engine. Lugging is driving too slowly in too
high a gear resulting engine buck-
ing. 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.
Use your air conditioning sparingly. The air conditioning system is
operated by engine power so your
fuel economy is reduced when you
use it.
Open windows at high speeds can reduce fuel economy.
Fuel economy is less in crosswinds and headwinds. To help offset
some of this loss, slow down when
driving in these conditions. Keeping a vehicle in good operating
condition is important both for econ-
omy and safety. Therefore, have an
authorized HYUNDAI dealer perform
scheduled inspections and mainte-
nance.
WARNING - Engine off
during
motion
Never turn the engine off to
coast down hills or anytime the
vehicle is in motion. The power
steering and power brakes will
not function properly without the
engine running. Instead, keep
the engine on and downshift to
an appropriate gear for engine
braking effect. In addition, turn-
ing off the ignition while driving
could engage the steering wheel
lock resulting in loss of vehicle
steering which could cause
serious injury or death.

OWNER MAINTENANCE
The following lists are vehicle checks
and inspections that should be per-
formed by the owner or an author-
ized HYUNDAI dealer at the frequen-
cies indicated to help ensure safe,
dependable operation of your vehi-
cle.
Any adverse conditions should be
brought to the attention of your deal-
er as soon as possible.
These Owner Maintenance Checks
are generally not covered by war-
ranties and you may be charged for
labor, parts and lubricants used.Owner maintenance schedule
When you stop for fuel:
• Check the engine oil level.
Check coolant level in coolantreservoir.
Check the windshield washer fluid level.
Look for low or under-inflated tires.
While operating your vehicle:
Note any changes in the sound of the exhaust or any smell of
exhaust fumes in the vehicle.
Check for vibrations in the steering wheel. Notice any increased steer-
ing effort or looseness in the steer-
ing wheel, or change in its straight-
ahead position.
Notice if your vehicle constantly turns slightly or "pulls" to one side
when traveling on smooth, level
road.
When stopping, listen and check for unusual sounds, pulling to one
side, increased brake pedal travel
or "hard-to-push" brake pedal.
If any slipping or changes in the operation of your transaxle occurs,
check the transaxle fluid level.
Check automatic transaxle P (Park) function.
Check parking brake.
Check for fluid leaks under your vehicle (water dripping from the air
conditioning system during or after
use is normal).
WARNING
Be careful when checking your
engine coolant level when the
engine is hot. Scalding hot
coolant and steam may blow
out under pressure. This could
cause burns or other serious
injury.

Maintenance
At least monthly:
Check coolant level in the enginecoolant reservoir.
Check the operation of all exterior lights, including the stoplights, turn
signals and hazard warning flash-
ers.
Check the inflation pressures of all tires including the spare.
At least twice a year
(i.e., every Spring and Fall) :
Check radiator, heater and air con- ditioning hoses for leaks or dam-
age.
Check windshield washer spray and wiper operation. Clean wiper
blades with clean cloth dampened
with washer fluid.
Check headlight alignment.
Check muffler, exhaust pipes, shields and clamps.
Check the lap/shoulder belts for wear and function.
Check for worn tires and loose wheel lug nuts.
At least once a year :
Clean body and door drain holes.
Lubricate door hinges and checks,and hood hinges.
Lubricate door and hood locks and latches.
Lubricate door rubber weather- strips.
Check the air conditioning system.
Inspect and lubricate automatic transaxle linkage and controls.
Clean battery and terminals.
Check the brake fluid level.
