Features of your vehicle
Malfunction indicator lamp(MIL) (check engine light) (if equipped)
This indicator light is part of the Engine
Control System which monitors various
emission control system components. If
this light illuminates while driving, it indi-
cates that a potential problem has been
detected somewhere in the emissioncontrol system. This light will also illuminate when the
ignition switch is turned to the ON posi-
tion, and will go out in a few seconds
after the engine is started. If it illuminates
while driving, or does not illuminate when
the ignition key is turned to the ON posi-
tion, take your vehicle to your nearest
authorised Hyundai dealer and have the
system checked.
Generally, your vehicle will continue to be
drivable, but have the system checked by
an authorised Hyundai dealer promptly.
Engine coolant tempera-ture warning light
This warning light shows the temperature of the engine coolant when the ignition
switch is ON. The warning light illumi-
nates if the temperature of the engine
coolant is above 120°C (248°F) and the
warning light turns off if the temperature
of the engine coolant is below 115°C(239°F).
If the warning light illuminates, pull over
and stop as soon as possible and turn off
the engine. Then open the hood and
check the coolant level (If your vehicle
overheats, refer to “If the engine over-
heats” in the Index.) and the water pump
drive belt. If you suspect cooling system
trouble, have your cooling system
checked by a Hyundai dealer as soon as
possible.
CAUTION
Prolonged driving with the
Emission Control SystemMalfunction Indicator Light ( ) illuminated may cause
damage to the emission controlsystems which could effect dri- vability and/or fuel economy.

If the EmissionControl System
Malfunction Indicator Light ( ) illuminates, potential catalytic converter damage is possiblewhich could result in loss of
engine power. Have the EngineControl System inspected as soonas possible by an authorised
Hyundai dealer.
WARNING
Never remove the radiator cap
when the engine is hot. The enginecoolant is under pressure and
could erupt and cause severe
burns. Wait until the engine is cool
before removing the radiator cap.

Driving your vehicle
Your vehicle's fuel economy depends
mainly on your style of driving, where you
drive and when you drive.
Each of these factors affects how many
kilometers you can get from a litre of fuel.
To operate your vehicle as economically
as possible, use the following driving
suggestions to help save money in bothfuel and repairs:
Drive smoothly. Accelerate at a moder-ate rate. Don't make “kangaroo” 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
possible. Always maintain a safe dis-
tance from other vehicles so you can
avoid unnecessary braking. This also
reduces brake wear.
Drive at a moderate speed. The faster you drive, the more fuel your car uses.
Driving at a moderate speed, especial-
ly on the highway, is one of the most
effective ways to reduce fuel consump-tion. Don't "ride" the brake or clutch pedal.
This can increase fuel consumption
and also increase wear on these com-
ponents. 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.
Take care of your tyres. Keep them inflated to the recommended pressure.
Incorrect inflation, either too much or
too little, results in unnecessary tyre
wear. Check the tyre pressures at leastonce a month.
Be sure that the wheels are aligned correctly. Improper alignment can
result from hitting curbs or driving too
fast over irregular surfaces. Poor align-
ment causes faster tyre wear and may
also result in other problems as well as
greater fuel consumption.
Keep your car in good condition. For better fuel economy and reduced
maintenance costs, maintain your carin accordance with the maintenance
schedule in Section 7. If you drive your
car in severe conditions, more frequentmaintenance is required (see Section
7 for details). Keep your car clean. For maximum
service, your vehicle 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 con-
sumption and also contribute to corro-sion.
Travel lightly. Don't carry unnecessary weight in your car. Weight reduces fuel
economy.
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.
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 plac-
ing the vehicle in gear. In very cold
weather, however, give your engine a
slightly longer warm-up period.
Don't “labour” or “over-rev” the engine. Labouring is driving too slowly in toohigh 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 avoid-
ed by shifting at the recommended
speeds.
ECONOMICAL OPERATION

533
Driving your vehicle
Higher speed motoring
Tyres:
Adjust the tyre inflation pressures to
specification. Low tyre inflation pressures
will result in overheating and possible
failure of the tyres.
Avoid using worn or damaged tyres
which may result in reduced traction or
tyre failure.
✽✽NOTICE
Never exceed the maximum tyre infla-
tion pressure shown on the tyres.
Fuel, engine coolant and engine oil:
High speed travel consumes more fuel
than urban motoring. Do not forget to
check both engine coolant and engineoil.
Drive belt:
A loose or damaged drive belt may result
in overheating of the engine.
WARNING
Underinflated or overinflated tyres can cause poor handling,
loss of vehicle control, and sud-den tyre failure leading to acci-
dents, injuries, and even death.
Always check the tyres for proper
inflation before driving. For prop-
er tyre pressures, refer to section
8, “Tyres and wheels”.
Driving on tyres with no or insuf- ficient tread is dangerous. Worn-out tyres can result in loss of
vehicle control, collisions, injury,
and even death. Worn-out tyresshould be replaced as soon as
possible and should never be
used for driving. Always check
the tyre tread before driving your
car. For further information and
tread limits, refer to section 7,
“Tyres and wheels”.

OWNER MAINTENANCE
The following lists are vehicle checks and
inspections that should be performed by
the owner or an authorised Hyundaidealer at the frequencies indicated to
help ensure safe, dependable operation
of your vehicle.
Any adverse conditions should be
brought to the attention of your dealer as
soon as possible.
These Owner Maintenance Checks are
generally not covered by warranties and
you may be charged for labour, parts and
lubricants used. Owner maintenance schedule
When you stop for fuel:
Check the engine oil level.
Check coolant level in coolant reser-
voir.
Check the windshield washer fluid level.
Look for low or under-inflated tyres.
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 steering
effort or looseness in the steering
wheel, or change in its straight-aheadposition.
Notice if your vehicle constantly turns slightly or “pulls” to one side when trav-
elling 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 oper- ation of your transaxle occurs, check
the transaxle fluid level.
Check automatic transaxle P (Park) function.
Check hand brake.
Check for fluid leaks under your vehicle (water dripping from the air condition-
ing system during or after use is nor-mal).
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.

TYRES AND WHEELS
Tyre care
For proper maintenance, safety, and
maximum fuel economy, you must
always maintain recommended tyre infla-
tion pressures and stay within the load
limits and weight distribution recom-
mended for your vehicle. Recommended cold tyre inflation pressures All tyre pressures (including the spare)
should be checked every day when the
tyres are cold. “Cold Tyres” means the
vehicle has not been driven for at least
three hours or driven less than 1.6 km(one mile).
Recommended pressures must be main-
tained for the best ride, top vehicle han-
dling, and minimum tyre wear. All specifications (sizes and pressures)
can be found on a label attached to the
vehicle.
WARNING - Tyre underin-
flation
Severe underinflation (70 kPa (10
psi) or more) can lead to severe
heat build-up, causing blowouts,tread separation and other tyre fail-ures that can result in the loss of
vehicle control leading to severe
injury or death. This risk is much
higher on hot days and when driv-
ing for protracted periods at highspeeds.

Maintenance
WARNING - Tyre inflation
Overinflation or underinflation can
reduce tyre life, adversely affect
vehicle handling, and lead to sud-
den tyre failure. This could result in
loss of vehicle control and potential
injury.
CAUTION - Tyre pressure
Always observe the following:
Check tyre pressure when the tyres are cold. (After vehicle hasbeen parked for at least threehours or hasn't been driven more
than 1.6 km (one mile) since start- up.)
Check the pressure of your spare tyre each time you check thepressure of other tyres.
Never overload your vehicle. Be careful not to overload a vehicleluggage rack if your vehicle is equipped with one.
Worn, old tyres can cause acci- dents. If your tread is badly worn,or if your tyres have been dam- aged, replace them.
CAUTION
Underinflation also results in
excessive wear, poor handlingand reduced fuel economy. Wheeldeformation also is possible.
Keep your tyre pressures at theproper levels. If a tyre frequentlyneeds refilling, have it checked byan authorised Hyundai dealer.
Overinflation produces a harsh ride, excessive wear at the centreof the tyre tread, and a greaterpossibility of damage from road
hazards.
CAUTION
Warm tyres normally exceed rec- ommended cold tyre pressuresby 28 to 41 kPa (4 to 6 psi). Do notrelease air from warm tyres to
adjust the pressure or the tyres will be underinflated.
Be sure to reinstall the tyre infla- tion valve caps. Without the valvecap, dirt or moisture could get
into the valve core and cause air leakage. If a valve cap is missing,install a new one as soon as pos-
sible.
