Safety features of your vehicle
The front air bag modules are locat-
ed in the center of the steering
wheel, in the front passenger's panel
above the glove box and in the dri-
ver’s side knee bolster. When the
SRSCM detects a sufficiently severe
impact to the front of the vehicle, it
will automatically deploy the front air
bags.Upon deployment, tear seams mold-
ed directly into the pad covers will
separate under pressure from the
expansion of the air bags. Further
opening of the covers then allows full
inflation of the air bags.

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 (kilometers) you can get
from a gallon (liter) of fuel. To operate
your vehicle as economically as pos-
sible, use the following driving sug-
gestions to help save money in both
fuel and repairs:
Drive smoothly. Accelerate at a
moderate rate. Don't make "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
car uses. Driving at a moderate
speed, especially on the highway,
is one of the most effective ways to
reduce fuel consumption. Don't "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 car in good condition. For
better fuel economy and reduced
maintenance costs, maintain your
car in accordance with the mainte-
nance 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 materi-
als. 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 consumption and
also contribute to corrosion.
Travel lightly. Don't carry unneces- sary 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.

Driving your vehicle
Driving in flooded areas
Avoid driving through flooded areas
unless you are sure the water is no
higher than the bottom of the wheel
hub. Drive through any water slowly.
Allow adequate stopping distance
because brake performance may be
affected.
After driving through water, dry the
brakes by gently applying them sev-
eral times while the vehicle is moving
slowly.
Driving off-road
Drive carefully off-road because your
vehicle may be damaged by rocks of
roots of trees. Become familiar with
the off-road conditions where you
are going to drive before you begin
driving.
Specification when the tires are cold
(not after driving long distances).
Highway driving
Tires
Adjust the tire inflation pressures to
specification when the tires are cold
(not after driving long distances).
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 failure.
✽ ✽NOTICE
Never exceed the maximum tire
inflation pressure shown on the tires.
OMG015008
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 for
proper inflation before driv-
ing. For proper tire pressures,
refer to “Tires and wheels” in
section 8.
Driving on tires with no or insufficient tread is danger-
ous. Worn-out tires can result
in loss of vehicle control, col-
lisions, 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) TPMS malfunction indicator
(2) Low tire pressure indicator(Shown on the LCD display) Each tire, including the spare (if pro-
vided), should be checked monthly
when cold and inflated to the recom-
mended pressure 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
placard or tire inflation pressure
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
indicator when one or more of your
tires is significantly under-inflated.
Accordingly, when the low tire pres-
sure indicator 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
indicator.
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 indicator. When
the system detects a malfunction,
the indicator will flash for approxi-
mately one minute and then remain
continuously illuminated. This
sequence will continue upon subse-
quent vehicle start-ups as long as
the malfunction exists. When the
malfunction indicator is illuminated,
the system may not be able to detect
or signal low tire pressure as intend-
ed. TPMS malfunctions may occur
for a variety of reasons, including the
installation of replacement or alter-
nate tires or wheels on the vehicle
that prevent the TPMS from function-
ing 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 proper-
ly.
✽ ✽
NOTICE
If the TPMS indicator does not illu-
minate for 3 seconds when the igni-
tion switch is turned to the ON posi-
tion or engine is running, or if it
comes on after blinking for approxi-
mately one minute, take your car to
your nearest authorized HYUNDAI
dealer and have the system checked.
Low tire pressure indicator
When the tire pressure monitoring
system warning indicator is illuminat-
ed, one or more of your tires is sig-
nificantly under-inflated.
If the indicator illuminates, immedi-
ately reduce your speed, avoid hard
cornering and anticipate increased
stopping distances. You should check
your tires as soon as possible. Inflate the tires to the proper pres-
sure as indicated on the vehicle’s
placard or tire inflation pressure label
located on the driver’s side center pil-
lar outer panel. If you cannot reach a
service station or if the tire cannot
hold the newly added air, replace the
low pressure tire with the spare tire.
Then the Low Tire Pressure indicator
may flash for approximately one
minute and then remain continuously
illuminated after restarting and about
20 minutes of continuous driving
before you have the low pressure tire
repaired or replaced on the vehicle.
CAUTION
In winter or cold weather, the
low tire pressure indicator maybe illuminated if the tire pres-sure was adjusted to the recom-mended tire inflation pressurein warm weather. It does notmean your TPMS is malfunction-ing because the decreased tem-perature leads to a lowering oftire pressure.

What to do in an emergency
TPMS (Tire Pressure
Monitoring System)
malfunction indicator
The TPMS malfunction indicator will
illuminate after it blinks for approxi-
mately one minute when there is a
problem with the Tire Pressure
Monitoring System. If the system is
able to correctly detect an under
inflation warning at the same time as
system failure then it will illuminate
the TPMS malfunction indicator.
Have the system checked by an
authorized HYUNDAI dealer as soon
as possible to determine the cause
of the problem.
WARNING - Low pressure
damage
Significantly low tire pressure
makes the vehicle unstable and
can contribute to loss of vehicle
control and increased braking
distances.
Continued driving on low pres-
sure tires can cause the tires to
overheat and fail.
(Continued) When you drive your vehiclefrom a warm area to a cold areaor from a cold area to a warmarea, or the outside temperatureis higher or lower, you shouldcheck the tire inflation pressureand adjust the tires to the rec-ommended cold tire inflationpressure.CAUTION
The TPMS malfunction indica- tor may be illuminated if thevehicle is moving around elec-tric power supply cables orradios transmitter such as atpolice stations, governmentpublic offices, broadcastingstations, military installations,airports, or transmitting tow-ers, etc. This can interfere withnormal operation of the TirePressure Monitoring System(TPMS).
The TPMS malfunction indica- tor may illuminate if snowchains or some separatelypurchased devices such asnotebook computers, mobilecharger, remote starter, navi-gation etc. are used in thevehicle. This can interfere withnormal operation of the TirePressure Monitoring System(TPMS).

613
What to do in an emergency
Allow the tire to cool before measur-
ing the inflation pressure. Always be
sure the tire is cold before inflating to
the recommended pressure.This device complies with Part
15 of the FCC rules.
Operation is subject to the following
two conditions:
1. This device may not cause harm-ful interference, and
2. This device must accept any inter- ference received, including inter-
ference that may cause undesired

WARNING - Protecting
TPMS
Tampering with, modifying, or
disabling the Tire Pressure
Monitoring System (TPMS)
components may interfere with
the system's ability to warn the
driver of low tire pressure con-
ditions and/or TPMS malfunc-
tions. Tampering with, modify-
ing, or disabling the Tire
Pressure Monitoring System
(TPMS) components may void
the warranty for that portion of
the vehicle.
WARNING - TPMS
The TPMS cannot alert you to severe and sudden tire dam-
age caused by external factors
such as nails or road debris.
If you feel any vehicle instabil- ity, immediately take your foot
off the accelerator, apply the
brakes gradually and with
light force, and slowly move to
a safe position off the road.
CAUTION
Changes or modifications notexpressly approved by the partyresponsible for compliancecould void the user’s authorityto operate the equipment.
CAUTION
Do not use any tire sealantexcept the Tire Mobility Kitapproved by HYUNDAI if yourvehicle is equipped with a TirePressure Monitoring System.The liquid sealant can damagethe tire pressure sensors.

What to do in an emergency
To prevent the jack, jack handle,
wheel lug nut wrench and spare tire
from rattling while the vehicle is in
motion, store them properly.
Important - use of temporary
compact spare tire
If your vehicle is equipped with a com-
pact spare tire, it will take up less
space than a regular-size tire. This tire
is smaller than a conventional tire and
is designed for temporary use only.
CAUTION
Your vehicle has metric threadson the wheel studs and nuts.Make certain during wheelremoval that the same nuts thatwere removed are reinstalled -or, if replaced, that nuts withmetric threads and the samechamfer configuration are used.Installation of a non-metricthread nut on a metric stud orvice-versa will not secure thewheel to the hub properly andwill damage the stud so that itmust be replaced.
Note that most lug nuts do nothave metric threads. Be sure touse extreme care in checkingfor thread style before installingaftermarket lug nuts or wheels.If in doubt, consult an author-ized HYUNDAI dealer.
WARNING - Wheel studs
If the studs are damaged, they
may lose their ability to retain
the wheel. This could lead to the
loss of the wheel and a collision
resulting in serious injuries.
WARNING - Inadequate
spare tire
pressure
Check the inflation pressures
as soon as possible after
installing the spare tire. Adjust
it to the specified pressure, if
necessary. Refer to “Tires and
wheels” section 8.
CAUTION
You should drive carefully when the compact spare is inuse. The compact spareshould be replaced by theproper conventional tire andrim at the first opportunity.
Do not use more than one compact spare tire at a time.

The compact spare should be inflat-
ed to 60 psi (420 kPa).
✽ ✽
NOTICE
Check the inflation pressure after
installing the spare tire. Adjust it to
the specified pressure, as necessary.
When using a temporary compact
spare tire, observe the following pre-
cautions:
Under no circumstances should you
exceed 50 mph (80 km/h); a higher
speed could damage the tire.
Ensure that you drive slowly enough for the road conditions to avoid all
hazards. Any road hazard, such as a
pothole or debris, could seriously
damage the compact spare.
Any continuous road use of this tire could result in tire failure, loss of
vehicle control, and possible per-
sonal injury.
Do not exceed the vehicle’s maxi- mum load rating or the load-carry-
ing capacity shown on the sidewall
of the compact spare tire.
Avoid driving over obstacles. The compact spare tire diameter is
smaller than the diameter of a con-
ventional tire and reduces the
ground clearance approximately 1
inch (25 mm), which could result in
damage to the vehicle.
Do not take the vehicle through an automatic car wash while the com-
pact spare tire is installed. Do not use tire chains on the com-
pact spare tire. Because of the small-
er size, a tire chain will not fit proper-
ly. This could damage the vehicle
and result in loss of the chain.
Do not use the compact spare tire on any other vehicle because this
tire has been designed especially
for your vehicle.
The compact spare tire’s tread life is shorter than a regular tire. Inspect
your compact spare tire regularly
and replace worn compact spare
tires with the same size and design,
mounted on the same wheel.
The compact spare tire should not be used on any other wheels, nor
should standard tires, snow tires,
wheel covers or trim rings be used
with the compact spare wheel. If
such use is attempted, damage to
these items or other car compo-
nents may occur.
Do not use more than one compact spare tire at a time.
Do not tow a trailer while the com- pact spare tire is installed.
WARNING
The temporary compact spare
tire is for emergency use only.
Do not operate your vehicle on
this compact spare at speeds
over 50 mph (80 km/h). The
original tire should be repaired
or replaced as soon as is possi-
ble to avoid failure of the spare
possibly leading to personal
injury or death.
