Driving your vehicle30 5Your 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 (kilometers) you can get from a gal-
lon (liter) of fuel. To operate your vehicle
as economically as possible, use the fol-
lowing driving suggestions to help save
money in both fuel and repairs:
Drive smoothly. Accelerate at a moder-
ate 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 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 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.
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 tire 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 car
in accordance with the maintenance
schedule in Section 7. If you drive your
car in severe conditions, more frequent
maintenance 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 "lug" or "over-rev" the engine.
Lugging is driving too slowly in too
high 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

Driving your vehicle34 5Higher speed motoringTires:Adjust the tire inflation pressures to
specification. 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 fail-
ure.✽ ✽
NOTICENever 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 forget to
check both engine coolant and engine
oil.Drive belt:A loose or damaged drive belt may result
in overheating of the engine.
WARNING
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.
Always check the tires for proper
inflation before driving. For prop-
er tire pressures, refer to section
9, “Tires and wheels”.
Driving on tires with no or insuffi-
cient tread is dangerous. Worn-
out tires can result in loss of
vehicle control, collisions, injury,
and even death. Worn-out tires
should be replaced as soon as
possible and should never be
used for driving. Always check
the tire tread before driving your
car. For further information and
tread limits, refer to section 7,
“Tires and wheels”.

What to do in an emergency
TIRES PRESSURE MONITORING SYSTEM (TPMS) (IF EQUIPPED) (1) Low Tire Pressure Telltale
(2) TPMS Malfunction Indicator
Each tire, including the spare (if pro-
vided), should be checked monthly
when cold and inflated to the inflation
pressure recommended by the vehi-
cle manufacturer on the vehicle plac-
ard or tire inflation pressure label. (If
your vehicle has tires of a different
size than the size indicated on the
vehicle placard or tire inflation pres-
sure label, you should determine the
proper inflation 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 pressure telltale illuminates, you
should stop and check your tires as
soon as possible, and inflate them to
the proper pressure. Driving on a
significantly under-inflated tire caus-
es 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 han-
dling 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 provided by a
separate telltale, which displays the
symbol "TPMS" when illuminated.
When the malfunction indicator is
illuminated, the system may not be
able to detect or signal low tire pres-
sure as intended. TPMS malfunc-
tions may occur for a variety of rea-
sons, including the installation of
replacement or alternate tires or
wheels on the vehicle that prevent the
TPMS from functioning properly.
Always check the TPMS malfunction
indicator after replacing one or more
tires or wheels on your vehicle to
ensure that the replacement or alter-
nate tires and wheels allow the TPMS
to continue to function properly.

Maintenance
OWNER MAINTENANCE The following lists are vehicle checks and
inspections that should be performed 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 dealer as
soon as possible.
These Owner Maintenance Checks are
generally not covered by warranties 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 coolant reser-
voir.
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 steering
effort or looseness in the steering
wheel, or change in its straight-ahead
position.
Notice if your vehicle constantly turns
slightly or “pulls” to one side when trav-
eling 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 parking 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.

Maintenance32 7TIRES 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 inflation
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
one mile (1.6 km).
Recommended pressures must be
maintained for the best ride, top vehi-
cle handling, and minimum tire wear.All specifications (sizes and pres-
sures) can be found on a label
attached to the driver’s side center
pillar.
WARNING - Tire underin-
flation
Severe underinflation (10 psi
(70 kPa) or more) can lead to
severe heat build-up, causing
blowouts, tread separation and
other tire failures 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 driving
for long periods at high speeds.
OHD086003
WARNING
Underinflated or overinflated
tires can cause poor handling,
loss of vehicle control, and
sudden tire failure leading to
accidents, injuries, and even
death. Always check tires are
properly inflated before driv-
ing.
Driving on tires with no or
insufficient tread is danger-
ous. Worn-out tires can result
in loss of vehicle control, col-
lisions, and injury and even
death. Worn-out tires should
be replaced as soon as possi-
ble and should never be used
for driving. Always check tire
tread before driving your car.

Maintenance
WARNING - Tire inflation
Overinflation or underinflation
can reduce tire life, adversely
affect vehicle handling, and
lead to sudden tire failure. This
could result in loss of vehicle
control and potential injury.
CAUTION - Tire pressure
Always observe the following:
Check tire pressure when the
tires are cold. (After vehicle
has been parked for at least
three hours or hasn't been
driven more than one mile (1.6
km) since startup.)
Check the pressure of your
spare tire each time you check
the pressure of other tires.
Never overload your vehicle.
Be careful not to overload a
vehicle luggage rack if your
vehicle is equipped with one.
Worn, old tires can cause acci-
dents. If your tread is badly
worn, or if your tires have
been damaged, replace them.
CAUTION
Underinflation also results in
excessive wear, poor handling
and reduced fuel economy.
Wheel deformation also is
possible. Keep your tire pres-
sures at the proper levels. If a
tire frequently needs refilling,
have it checked by an author-
ized Hyundai dealer.
Overinflation produces a
harsh ride, excessive wear at
the center of the tire tread, and
a greater possibility of dam-
age from road hazards.
CAUTION
Warm tires normally exceed
recommended cold tire pres-
sures by 4 to 6 psi (28 to 41
kPa). Do not release air from
warm tires to adjust the pres-
sure or the tires will be under-
inflated.
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.
