Safety features of your vehicle
The front air bag modules are located
both in the center of the steering wheel
and in the front passenger's panel above
the glove box. 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 molded
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.
A fully inflated air bag, in combination
with a properly worn seat belt, slows the
driver's or the passenger's forward
motion, reducing the risk of head and
chest injury. After complete inflation, the air bag
immediately starts deflating, enabling the
driver to maintain forward visibility and
the ability to steer or operate other con-
trols.

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 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 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 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 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.

Tires
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.
✽✽NOTICE
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 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 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 tiresshould 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.

If you have a tire gauge, remove the
valve cap and check the air pressure.
If the pressure is lower than recom-
mended, drive slowly to the nearest
service station and inflate to the cor-
rect pressure. If it is too high, adjust
it until it is correct. Always reinstall
the valve cap after checking or
adjusting tire pressure. If the cap is
not replaced, air may leak from the
tire. If you lose a valve cap, buyanother and install it as soon as pos-
sible.
After you have changed wheels,
always secure the flat tire in its place
and return the jack and tools to their
proper storage locations. To prevent the jack, jack handle,
wheel lug nut wrench and spare tire
from rattling while the vehicle is in
motion, store them properly.CAUTION
Your vehicle has metric threads
on the wheel studs and nuts.Make certain during wheel removal that the same nuts thatwere removed are reinstalled -or, if replaced, that nuts withmetric threads and the same chamfer configuration are used.Installation of a non-metricthread nut on a metric stud or vice-versa will not secure thewheel to the hub properly andwill damage the stud so that it must be replaced.
Note that most lug nuts do nothave metric threads. Be sure touse extreme care in checkingfor thread style before installing aftermarket 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 theloss of the wheel and a collisionresulting 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” sec-tion 8.

Important - use of compact spare tire(if equipped)
Your vehicle is equipped with a com-
pact spare tire. This compact spare
tire takes up less space than a regu-
lar-size tire. This tire is smaller than a
conventional tire and is designed for
temporary use only.
The compact spare should be inflat-
ed to 420 kPa (60 psi).
✽✽NOTICE
Check the inflation pressure after
installing the spare tire. Adjust it to
the specified pressure, as necessary.
When using a compact spare tire,
observe the following precautions:
Under no circumstances should you exceed 80 km/h (50 mph); 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 issmaller than the diameter of a con-
ventional tire and reduces the
ground clearance approximately25 mm (1 inch), which could result
in damage to the vehicle.
CAUTION
You should drive carefully
when the compact spare tireis in use. The compact sparetire should be replaced by theproper conventional tire and rim at the first opportunity.
The operation of this vehicle is not recommended withmore than one compact sparetire in use at the same time.
WARNING
The compact spare tire is for
emergency use only. Do not
operate your vehicle on this
compact spare at speeds over
80 km/h (50 mph). The originaltire should be repaired or
replaced as soon as possible to
avoid failure of the spare possi-
bly leading to personal injury ordeath.

Fire extinguisher
If there is small fire and you know how to
use the fire extinguisher, take the follow-
ing steps carefully.
1. Pull the pin at the top of the extin- guisher that keeps the handle from being accidentally pressed.
2. Aim the nozzle toward the base of the fire.
3. Stand approximately 2.5 m (8 ft) away from the fire and squeeze the handle
to discharge the extinguisher. If you
release the handle, the discharge will
stop.
4. Sweep the nozzle back and forth at the base of the fire. After the fire appears
to be out, watch it carefully since it
may re-ignite. F110200AUN
First aid kit
There are some items such as scissors,
bandage and adhesive tape and etc. in
the kit to give first aid to an injured per-son.
F110300AUN
Triangle reflector
Place the triangle reflector on the road to
warn oncoming vehicles during emer-
gencies, such as when the vehicle is
parked by the roadside due to any prob-
lems.
F110400AUN
Tire pressure gauge (If equipped)
Tires normally lose some air in day-to-
day use, and you may have to add a few
pounds of air periodically and it is not
usually a sign of a leaking tire, but of nor-
mal wear. Always check tire pressurewhen the tires are cold because tire pres-
sure increases with temperature. To check the tire pressure, take the fol-
lowing steps;
1. Unscrew the inflation valve cap that is
located on the rim of the tire.
2. Press and hold the gauge against the tire valve. Some air will escape as you
begin and more will escape if you don't
press the gauge in firmly.
3. A firm non-leaking push will activate the gauge.
4. Read the tire pressure on the gauge to know whether the tire pressure is lowor high.
5. Adjust the tire pressures to the speci- fied pressure. Refer to “Tires and
wheels” in section 8.
6. Reinstall the inflation valve cap.

G030102ABH
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-
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 transmission occurs,
check the transmission fluid level.
Check automatic transmission 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). G030103AUN
At least monthly:
Check the coolant level in the engine
coolant reservoir.
Check the operation of all exterior lights, including the stoplights, turn sig-
nals and hazard warning flashers.
Check the inflation pressures of all tires including the spare. G030104AHM
At least twice a year
(i.e., every Spring and Fall):
Check the radiator, heater and air con- ditioning hoses for leaks or damage.
Check the windshield washer spray and wiper operation. Clean the wiper
blades with clean cloth dampened with
washer fluid.
Check the headlight alignment.
Check the muffler, exhaust pipes, shields and clamps.
Check the lap/shoulder belts for wear and function.
Check for worn tires and loose wheel lug nuts.

CAUTION
Underinflation also results in
excessive wear, poor handlingand reduced fuel economy. Wheel deformation also ispossible. 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 atthe center of the tire tread, anda greater possibility of dam-age from road hazards.
TIRES AND WHEELS
G200100AUN 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. G200200AEN 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 than1.6 km (one mile).
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 section8. All specifications (sizes and pres-
sures) can be found on a label
attached to the vehicle.
WARNING - Tire underin-
flation
Severe underinflation can lead
to severe heat build-up, causing
blowouts, tread separation andother 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.

Checking tire inflation pressure
Check your tires once a month or
more.
Also, check the tire pressure of the
spare tire. G200301AEN
How to check
Use a good quality gage to check tire
pressure. You can not tell if your tires
are properly inflated simply by look-
ing at them. Radial tires may look
properly inflated even when they're
underinflated.
Check the tire's inflation pressure
when the tires are cold. - "Cold"
means your vehicle has been sitting
for at least three hours or driven nomore than 1.6 km (1 mile).
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 vehiclehas been parked for at leastthree hours or hasn't beendriven more than 1.6 km (one mile) since startup.)
Check the pressure of your spare tire each time you checkthe pressure of other tires.
Never overload your vehicle. Be careful not to overload avehicle luggage rack if your vehicle is equipped with one.
Worn, old tires can cause acci- dents. If your tread is badlyworn, or if your tires havebeen damaged, replace them.
CAUTION
Warm tires normally exceed recommended cold tire pres-sures by 28 to 41 kPa (4 to 6psi). Do not release air fromwarm tires to adjust the pres- sure or the tires will be under-inflated.
Be sure to reinstall the tire inflation valve caps. Withoutthe valve cap, dirt or moisture could get into the valve coreand cause air leakage. If avalve cap is missing, install a new one as soon as possible.
