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.
WARNING
If any of the following conditions
occurs, this indicates a malfunction
of the SRS. Have an authorized
HYUNDAI dealer inspect the air bag
system as soon as possible.
The light does not turn on briefly
when you turn the ignition ON.
The light stays on after illuminat- ing for approximately 6 seconds.
The light comes on while the vehicle is in motion.
The light blinks when the engine start/stop button is in ON position.

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 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.

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 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 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.

✽
NOTICE
If the TPMS indicator does not illu-
minate for 3 seconds when the
engine start/stop button is pressed to
the ON position or engine is run-
ning, or if it comes on after blinking
for approximately one minute, take
your car to your nearest authorized
HYUNDAI dealer and have the sys-
tem checked.
Low tire pressure tell-
tale
When the tire pressure monitoring
system warning indicator is illuminat-
ed, one or more of your tires is sig-
nificantly under-inflated.
If the telltale illuminates, immediately
reduce your speed, avoid hard cor-
nering and anticipate increased stop-
ping distances. You should stop and
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, use the inflator in the
Tire Mobility Kit located in the trunk.
If the tire cannot hold the newly
added air, or will not hold air after the
sealant is added, repair the tire.
The Low Tire Pressure telltale may
flash for approximately one minute
and then remain continuously illumi-
nated after restarting and about 20
minutes of continuous driving before
you have the low pressure tire
repaired and replaced on the vehicle.CAUTION
In winter or cold weather, the low tire pressure telltale may beilluminated if the tire pressurewas 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 proportionallowering of tire pressure.
When you drive your vehiclefrom a warm area to a cold areaor from a cold area to a warmarea, or the outside temperatureis greatly higher or lower, youshould check the tire inflationpressure and adjust the tires tothe recommended tire inflationpressure.

What to do in an emergency
You may not be able to identify a low
tire by simply looking at it. Always
use a good quality tire pressure
gauge to measure the tire's inflation
pressure. Please note that a tire that
is hot (from being driven) will have a
higher pressure measurement than a
tire that is cold.
A cold tire means the vehicle has
been sitting for 3 hours and driven for
less than 1 mile (1.6 km) in that 3
hour period.
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 harmful
interference, and
2.This device must accept any inter- ference received, including inter-
ference that may cause undesired
operation.
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.
WARNING - Protecting TPMS
Tampering with, modifying, or
disabling the Tire Pressure
Monitoring System (TPMS) com-
ponents may interfere with the
system's ability to warn the driv-
er of low tire pressure condi-
tions and/or TPMS malfunctions.
Tampering with, modifying, or
disabling the Tire Pressure
Monitoring System (TPMS) com-
ponents 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 fac-
tors 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 not
expressly approved by the partyresponsible for compliance couldvoid the user’s authority to operate the equipment.

What to do in an emergency
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, buy
another 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 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.
