Safety features of your vehicle
The front air bag modules are located in
the center of the steering wheel, in the
front passenger's panel above the glove
box and/or in the driver’s side knee bol-
ster. When the SRSCM detects a suffi-
ciently 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 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.
• 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 vehicle
Driving in flooded areas
Avoid driving through flooded areas
unless you are sure the water is no high-
er 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 several
times while the vehicle is moving slowly.
Driving off-road
Drive carefully off-road because your
vehicle may be damaged by rocks or
roots of trees. Become familiar with the
off-road conditions where you are going
to drive before you begin driving.Highway driving
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 infla-
tion 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) (IF EQUIPPED)
(1) Low Tire Pressure Telltale
(2) TPMS Malfunction Indicator
(3) Low Tire Pressure Position
Telltale (if equipped)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 effi-
ciency 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 oper-
ating properly. The TPMS malfunction
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 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
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 properly.
✽NOTICE
If the TPMS, Low Tire Pressure tell-
tale do not illuminate for 3 seconds
when the ignition switch is turned to
the ON position or engine is run-
ning, or if they remain illuminated
after coming on for approximately 3
seconds, take your car to your near-
est authorized HYUNDAI dealer
and have the system checked.
Low tire pressure tell-
tale
Low tire pressure posi-
tion telltale
When the tire pressure monitoring
system warning indicators are illumi-
nated, one or more of your tires is
significantly under-inflated. The low
tire pressure position telltale (supple-
mental) will indicate which tire is sig-
nificantly under-inflated by illuminat-
ing the corresponding position on the
LCD screen (if equipped).
If either telltale illuminates, immedi-
ately reduce your speed, avoid hard
cornering and anticipate increased
stopping distances. You should stop
and check your tires as soon as pos-
sible. Inflate the tires to the proper
pressure as indicated on the vehi-
cle’s placard or tire inflation pressure
label located on the driver’s side cen-
ter pillar 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.The Low Tire Pressure and Position
telltale will remain on until you have
the low pressure tire repaired and
replaced on the vehicle.
✽NOTICE
The spare tire is not equipped with a
tire pressure sensor.
CAUTION
In winter or cold weather, the
low tire pressure telltale may be
illuminated if the tire pressure
was adjusted to the recom-
mended tire inflation pressure
in warm weather. It does not
mean your TPMS is malfunction-
ing because the decreased tem-
perature leads to a proportional
lowering of tire pressure.
When you drive your vehicle
from a warm area to a cold area
or from a cold area to a warm
area, or the outside temperature
is greatly higher or lower, you
should check the tire inflation
pressure and adjust the tires to
the recommended tire inflation
pressure.

What to do in an emergency
TPMS (Tire Pressure
Monitoring System)
malfunction indicator
The TPMS malfunction indicator
comes on and stays on when there is
a problem with the Tire Pressure
Monitoring System. The system is
able to correctly detect an under-
inflation warning at the same time as
system failure then it will illuminate
both the TPMS malfunction and the
low tire pressure telltale. If the Front
Left sensor fails, the TPMS malfunc-
tion indicator illuminates, but if the
Front Right, Rear Left, or Rear Right
tire is under-inflated, the low tire
pressure and position telltales may
illuminate together with 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.TPMSCAUTION
• The TPMS malfunction indica-
tor may be illuminated if the
vehicle is moving around elec-
tric power supply cables or
radios transmitter such as at
police stations, government
and public offices, broadcast-
ing stations, military installa-
tions, airports, or transmitting
towers, etc. This can interfere
with normal operation of the
Tire Pressure Monitoring
System (TPMS).
• The TPMS malfunction indica-
tor may be illuminated if snow
chains are used or some sep-
arate electronic devices such
as notebook computer, mobile
charger, remote starter or nav-
igation etc., are used in the
vehicle. This can interfere with
normal operation of the Tire
Pressure Monitoring System
(TPMS).

What to do in an emergency
You may not be able 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 (from sitting station-
ary for at least 3 hours and driven
less than 1.6km (1 mile) during 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.
A cold tire means the vehicle has
been sitting for 3 hours and driven for
less than 1.6km (1 mile) in that 3
hour period.CAUTION
• Do not use any tire sealant if
your vehicle is equipped with
a Tire Pressure Monitoring
System. The liquid sealant can
damage the tire pressure sen-
sors.
• In order to correctly monitor
the tires with inflation, the 4
tire pressure monitoring sen-
sors should be exactly fitted
to each of the 4 driven wheel.
There should be no other sen-
sors in the vehicle include
spare tire, it may cause the
system couldn’t monitor the
tires with inflation correctly.
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 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.

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 wheel
removal that the same nuts that
were removed are reinstalled -
or, if replaced, that nuts with
metric threads and the same
chamfer configuration are used.
Installation of a non-metric
thread nut on a metric stud or
vice-versa will not secure the
wheel to the hub properly and
will damage the stud so that it
must be replaced.
Note that most lug nuts do not
have metric threads. Be sure to
use extreme care in checking
for 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 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” sec-
tion 8.
