Features of your vehicle
Low tire pressure telltale The low tire pressure telltale illuminates
when one or more of your tires is signifi-
cantly underinflated.
The low tire pressure telltale will illumi-
nate after it blinks for approximately one
minute when there is a problem with the
Tire Pressure Monitoring System.
If this occurs, have the system checked
by an authorized HYUNDAI dealer as
soon as possible.
For details, refer to the TPMS on chapter
6.
Automatic Transaxle shift
indicatorThe indicator displays which automatic
transaxle shift position is selected.Manual transaxle shift indicator (if equipped)This indicator informs you which gear is
desired while driving to save fuel.
For example
: Indicates that shifting up to the 3rdgear is desired (currently the shift
lever is in the 2nd gear).
: Indicates that shifting down to the 3rd gear is desired (currently the
shift lever is in the 4th gear).✽ ✽ NOTICEWhen the system is not working proper-
ly, up & down arrow indicator and Gear
are not displayed.
WARNING
- Low tire pres-
sure
Significantly low tire pressure
makes the vehicle unstable and can
contribute to loss of vehicle control
and increased braking distances.
Continued driving on tires with low
pressure will cause the tires to
overheat and fail.
WARNING
- Safe stopping
 The TPMS cannot alert you to
severe and sudden tire damage
caused by external factors.
 If you feel any vehicle instability, immediately take your foot off the
accelerator, apply the brakes
gradually and with light force,
and slowly move to a safe posi-
tion off the road.

Driving your vehicle36
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 pedal. This can
increase fuel consumption and also
increase wear on these components.
In addition, driving with your foot rest-
ing 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.ECONOMICAL OPERATION

Driving your vehicle
Highway drivingTiresAdjust 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 oilHigh speed travel consumes more fuel
than urban motoring. Do not forget to
check both engine coolant and engine
oil.Drive beltA 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 tires for proper
inflation before driving. For prop-
er tire pressures, refer to “Tires
and wheels” in section 8.
 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 “Tires and
wheels” in section 7.

What to do in an emergency
TIRE PRESSURE MONITORING SYSTEM (TPMS)(1) Low tire pressure telltale / 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 tire 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 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. TPMS
malfunctions may occur for a variety
of reasons, 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
telltale 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 proper-
ly.

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.
WARNING
- Maintenance work
 Performing maintenance work on
a vehicle can be dangerous. You
can be seriously injured while
performing some maintenance
procedures. If you lack sufficient
knowledge and experience or the
proper tools and equipment to do
the work, have it done by an
authorized HYUNDAI dealer.
 Working under the hood with the engine running is dangerous. It
becomes even more dangerous
when you wear jewelry or loose
clothing. These can become
entangled in moving parts and
result in injury. Therefore, if you
must run the engine while work-
ing under the hood, make certain
that you remove all jewelry (espe-
cially rings, bracelets, watches,
and necklaces) and all neckties,
scarves, and similar loose cloth-
ing before getting near the
engine or cooling fans.
OWNER MAINTENANCE
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
CAUTION
 Underinflation also results inexcessive wear, poor handlingand reduced fuel economy.Wheel deformation also ispossible. Keep your tire pres-sures at the proper levels. If atire frequently needs refilling,have it checked by an author-ized HYUNDAI dealer.
 Overinflation produces a harsh ride, excessive wear atthe center of the tire tread, anda greater possibility of dam-age from road hazards.
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 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, vehicle
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 driver’s side center
pillar.
WARNING - Tire underin-
flation
Severe underinflation 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.
