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 miles you can get from a gallon
of fuel. To operate your vehicle as
economically as possible, use the
following driving suggestions to help
save money in both fuel and repairs:
Drive smoothly. Accelerate at amoderate rate. Avoid making "jack-
rabbit" starts or full-throttle shifts
and maintain a steady cruising
speed. Don't race between stop-
lights. 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
distance from other vehicles so
you can avoid unnecessary brak-
ing. This also reduces brake wear. Drive at a moderate speed. The
faster you drive, the more fuel your
vehicle uses. Driving at a moderate
speed, especially on the highway,
is one of the most effective ways to
reduce fuel consumption.
Do not "ride" the brake 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 con-
sequences.
Take care of your tires. Keep them inflated to the recommended pres-
sure. Incorrect inflation, either too
much or too little, results in unnec-
essary tire wear. Check the tire
pressures at least once a month.
Be sure that the wheels are aligned correctly. Improper align-
ment 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. Keep your vehicle in good condi-
tion. For better fuel economy and
reduced maintenance costs, main-
tain your vehicle in accordance
with the maintenance schedule in
section 7. If you drive your vehicle
in severe conditions, more frequent
maintenance is required (see sec-
tion 7 for details).
Keep your vehicle clean. For best operation, 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 vehicle. This extra
weight can result in increased fuel
consumption and also contribute to
corrosion.
Travel lightly. Do not carry unnec- essary weight in your vehicle.
Weight reduces fuel economy.
Do not 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.

Highway driving
Tires
Adjust the tire inflation pressures to
specification. Low tire inflation pres-
sures 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.
Never exceed the maximum tire
inflation pressure shown on the tires.
Fuel, engine coolant and engine
oil
High speed travel consumes more
fuel than urban motoring. Do not for-
get to check both engine coolant and
engine oil.
Drive belt
A loose or damaged drive belt may
overheat the engine.
WARNING - Under/over
inflated tires
Always check the tires for proper
inflation before driving.
Underinflated or overinflated
tires can cause poor handling,
loss of vehicle control, and sud-
den tire failure leading to acci-
dents, injuries, and even death.
For proper tire pressures, refer to
“Tires and wheels” in section 8.
WARNING - Tire tread
Always check the tire tread
before driving your vehicle.
Worn-out tires can result in loss
of vehicle control, accidents,
injuries, and even death. Worn-
out tires should be replaced as
soon as possible. For further
information and tread limits,
refer to "Tires and wheels" in
section 7.

What to do in an emergency
86
TIRE PRESSURE MONITORING SYSTEM (TPMS)
(1) Low tire pressure telltale / TPMS malfunction indicator
(2) Low tire pressure position telltale (Shown on the LCD display) Each tire, including the spare (if pro-
vided), should be checked monthly
when cold and inflated to the inflation
pressure recommended by the vehicle
manufacturer on the vehicle placard or
tire inflation pressure label. (If your
vehicle has tires of a different size than
the size indicated on the vehicle plac-
ard or tire inflation pressure label, you
should determine the proper tire infla-
tion pressure for those tires.)
As an added safety feature, your
vehicle has been equipped with a tire
pressure monitoring system (TPMS)
that illuminates a low tire pressure
telltale when one or more of your
tires is significantly under-inflated.
Accordingly, when the low tire pres-
sure telltale illuminates, you should
stop and check your tires as soon as
possible, and inflate them to the
proper pressure. Driving on a signifi-
cantly under-inflated tire causes the
tire to overheat and can lead to tire
failure. Under-inflation also reduces
fuel efficiency and tire tread life, and
may affect the vehicle’s handling and
stopping ability. Please note that the TPMS is not a
substitute for proper tire mainte-
nance, and it is the driver’s responsi-
bility to maintain correct tire pres-
sure, even if under-inflation has not
reached the level to trigger illumina-
tion of the TPMS low tire pressure
telltale.
Your vehicle has also been equipped
with a TPMS malfunction indicator to
indicate when the system is not
operating properly. The TPMS mal-
function indicator is combined with
the low tire pressure telltale. When
the system detects a malfunction,
the telltale will flash for approximate-
ly one minute and then remain con-
tinuously illuminated. This sequence
will continue upon subsequent vehi-
cle start-ups as long as the malfunc-
tion exists. When the malfunction
indicator is illuminated, the system
may not be able to detect or signal
low tire pressure as intended.

OWNER MAINTENANCE
The following lists are vehicle checks
and inspections that should be per-
formed by the owner or an authorized
HYUNDAI dealer at the frequencies
indicated to help ensure safe,
dependable operation of your vehicle.
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.
Check the radiator and condenser. Check if the front of the radiator and
condenser are clean and not blocked
with leaves, dirt or insects etc.
If any of the above parts are
extremely dirty or you are not sure
of their condition, take your vehicle
to an authorized HYUNDAI dealer.
While operating your vehicle:
Note any changes in the sound ofthe 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- Hot coolant
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
injuries.

Maintenance
TIRES AND WHEELS
Tire care
For proper maintenance, safety, and
maximum fuel economy, you must
always maintain recommended tire
inflation pressures and stay within
the load limits and weight distribution
recommended for your vehicle.
Recommended cold tire infla-
tion pressures
All tire pressures (including the
spare) should be checked when the
tires are cold. “Cold Tires” means the
vehicle has not been driven for at
least three hours or driven less than
1 mile (1.6 km).
Recommended pressures must be
maintained for the best ride, top vehi-
cle handling, and minimum tire wear.
For recommended inflation pressure,
refer to “Tire and wheels” in section 8.All specifications (sizes and pres-
sures) can be found on a label
attached to the vehicle. Underinflation also results in
excessive wear, poor handling and
reduced fuel economy. Wheel
deformation also is possible. Keep
your tire pressures at the proper
levels. If a tire frequently needs
refilling, have it checked by an
authorized HYUNDAI dealer.
Overinflation produces a harsh ride, excessive wear at the center of the
tire tread, and a greater possibility
of damage from road hazards.
Warm tires normally exceed rec- ommended cold tire pressures by 4
to 6 psi (28 to 41 kPa). Do not
release air from warm tires to
adjust the pressure or the tires will
be underinflated.
Be sure to reinstall the tire inflation valve caps. Without the valve cap,
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 possible.OHG050081L
WARNING - Tire under
inflation
Inflate your tires consistent with
the instructions provided in this
manual. Severe underinflation
can lead to severe heat build-up,
causing blowouts, tread separa-
tion and other tire failures that
can result in the loss of vehicle
control leading to severe injury
or death. This risk is much high-
er on hot days and when driving
for long periods at high speeds.

Tire terminology and definitions
Air Pressure: The amount of air
inside the tire pressing outward on
the tire. Air pressure is expressed in
pounds per square inch (psi) or kilo-
pascal (kPa).
Accessory Weight: This means the
combined weight of optional acces-
sories. Some examples of optional
accessories are, automatic
transaxle, power seats, and air con-
ditioning.
Aspect Ratio : The relationship of a
tire's height to its width.
Belt: A rubber coated layer of cords
that is located between the plies and
the tread. Cords may be made from
steel or other reinforcing materials.
Bead: The tire bead contains steel
wires wrapped by steel cords that
hold the tire onto the rim.
Bias Ply Tire : A pneumatic tire in
which the plies are laid at alternate
angles less than 90 degrees to the
centerline of the tread. Cold Tire Pressure: The amount of
air pressure in a tire, measured in
pounds per square inch (psi) or kilo-
pascals (kPa) before a tire has built
up heat from driving.
Curb Weight: This means the weight
of a motor vehicle with standard and
optional equipment including the
maximum capacity of fuel, oil and
coolant, but without passengers and
cargo.
DOT Markings: A code molded into
the sidewall of a tire signifying that
the tire is in compliance with the U.S.
Department of Transportation motor
vehicle safety standards. The DOT
code includes the Tire Identification
Number (TIN), an alphanumeric des-
ignator which can also identify the
tire manufacturer, production plant,
brand and date of production.
GVWR: Gross Vehicle Weight Rating
GAWR FRT: Gross Axle Weight
Rating for the Front Axle.
GAWR RR: Gross Axle Weight
Rating for the Rear axle.(Continued)
If the tire is impacted, inspect the tire condition or contact anauthorized HYUNDAI dealer.
To prevent damage to the tire, inspect the tire condition andpressure every 1,800miles(3,000km).
CAUTION
It is not easy to recognize the tire damage with your owneyes. But if there is the slight-est hint of tire damage, eventhough you cannot see the tiredamage with your own eyes,have the tire checked orreplaced because the tiredamage may cause air leak-age from the tire.
If the tire is damaged by driv- ing on a rough road, off road,pothole, manhole, or curbstone, it will not be covered bythe warranty.
You can find out the tire infor- mation on the tire sidewall.
