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 any of the below happens, we rec-
ommend that the system be checked
by an authorized HYUNDAI dealer.
1.The low tire pressure telltale/
TPMS malfunction indicator does
not illuminate for 3 seconds when
the ignition switch is turned to the
ON or engine is running.
2. The TPMS malfunction indicator
remains illuminated after blinking
for approximately 1 minute.
3. The Low tire pressure position
telltale remains illuminated.
Low tire pressure
telltale
Low tire pres-
sure position
telltale
When the tire pressure monitoring
system warning indicators are illumi-
nated and warning massage dis-
played on the cluster LCD display,
one or more of your tires is signifi-
cantly under-inflated. The low tire
pressure position telltale light will
indicate which tire is significantly
under-inflated by illuminating the cor-
responding position light.
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 Telltale will
remain on and the TPMS Malfunction
Indicator may blink for one minute
and then remain illuminated (when
the vehicle is driven approximately
20 minutes at speed above 15.5 mph
(25 km/h)) until you have the low
pressure tire repaired and replaced
on the vehicle.

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.
Have the system checked by an
authorized HYUNDAI dealer as soon
as possible to determine the cause
of the problem.
✽ ✽
NOTICE
If there is a malfunction with the
TPMS, the low tire pressure position
telltale will not be displayed even
though the vehicle has an under-
inflated tire.
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.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.

Changing a tire with TPMS
If you have a flat tire, the Low Tire
Pressure and Position telltales will
come on. Have the flat tire repaired
by an authorized HYUNDAI dealer
as soon as possible or replace the
flat tire with the spare tire.
The spare tire (if equipped) does not
come with a tire pressure monitoring
sensor. When the low pressure tire or
the flat tire is replaced with the spare
tire, the Low Tire Pressure Telltale
will remain on. Also, the TPMS
Malfunction Indicator will illuminate
after blinking for one minute if the
vehicle is driven at speed above 15.5
mph (25 km/h) for approximately 20
minutes.Once the original tire equipped with
a tire pressure monitoring sensor is
reinflated to the recommended pres-
sure and reinstalled on the vehicle,
the Low Tire Pressure Telltale and
TPMS Malfunction Indicator will go
off within a few minutes.
If the indicators do not extinguish
after a few minutes, please visit an
authorized HYUNDAI dealer.
Each wheel is equipped with a tire
pressure sensor mounted inside the
tire behind the valve stem (except for
the spare tire). You must use TPMS
specific wheels. It is recommended
that you always have your tires serv-
iced by an authorized HYUNDAI
dealer as soon as possible.CAUTION
The TPMS malfunction indica-
tor may blink for approximate-
ly 1 minute and then remain
continuously illuminated if the
vehicle is moving around elec-
tric power supply cables or
radio 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 blink for approximate-
ly 1 minute and then remain
continuously illuminated if the
snow chains are used or some
separate electronic devices
such as notebook computer,
mobile charger, remote starter
or navigation etc., are used in
the vehicle. This can interfere
with normal operation of the
Tire Pressure Monitoring
System (TPMS).
CAUTION
Never use a puncture-repairing
agent not approved by HYUNDAI
dealer to repair and/or inflate a
low pressure tire. Tire sealant not
approved by HYUNDAI dealer
may damage the tire pressure
sensor.

What to do in an emergency
You may not be able to identify a tire
with low pressure by simply looking
at it. Always use a good quality tire
pressure gauge to measure. 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.
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 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 with light
force, and slowly move to a
safe position off the road.
CAUTION
Changes or modifications not
expressly approved by the party
responsible for compliance
could void the user’s authority
to operate the equipment.

617
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” section 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 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 compact spare tire,
observe the following precautions:
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.
CAUTION
You should drive carefully
when the compact spare tire
is in use. The compact spare
tire should be replaced by the
proper conventional tire and
rim at the first opportunity.
The operation of this vehicle
is not recommended with
more than one compact spare
tire 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
50 mph (80 km/h). The original
tire should be repaired or
replaced as soon as possible to
avoid failure of the spare possi-
bly leading to personal injury or
death.

OWNER MAINTENANCE
The following lists are vehicle checks
and inspections that should be per-
formed by the owner or an author-
ized HYUNDAI dealer at the frequen-
cies indicated to help ensure safe,
dependable operation of your vehi-
cle.
Any adverse conditions should be
brought to the attention of your deal-
er as soon as possible.
These Owner Maintenance Checks
are generally not covered by war-
ranties 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 the coolant level in coolant
reservoir.
Check the windshield washer fluid
level.
Look for low or under-inflated tires.
WARNING- Maintenance
work
Performing maintenance work
on a vehicle can be danger-
ous. 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 danger-
ous. 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 working
under the hood, make certain
that you remove all jewelry
(especially rings, bracelets,
watches, and necklaces) and
all neckties, scarves, and sim-
ilar loose clothing before get-
ting near the engine or cool-
ing fans.
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

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 steer-
ing effort or looseness in the steer-
ing wheel, or change in its straight-
ahead position.
Notice if your vehicle constantly
turns slightly or “pulls” to one side
when traveling 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
operation 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
conditioning system during or after
use is normal).
At least monthly:
Check the coolant level in the
engine coolant reservoir.
Check the operation of all exterior
lights, including the stoplights, turn
signals and hazard warning flash-
ers.
Check the inflation pressures of all
tires including the spare.
At least twice a year
(i.e., every Spring and Fall):
Check the radiator, heater and air
conditioning 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.

Maintenance
CAUTION
Underinflation also results in
excessive wear, poor handling
and reduced fuel economy.
Wheel deformation also is
possible. 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 at
the center of the tire tread, and
a 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 infla-
tion 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, top vehi-
cle 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 vehicle.
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.

Checking tire inflation pres-
sure
Check your tires once a month or
more.
Also, check the tire pressure of the
spare tire.
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 no
more than 1 mile (1.6 km).
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 vehicle
has been parked for at least
three hours or hasn't been
driven more than one mile (1.6
km) since startup.)
Check the pressure of your
spare tire each time you check
the pressure of other tires.
Never overload your vehicle.
Be careful not to overload a
vehicle luggage rack if your
vehicle is equipped with one.
Worn, old tires can cause acci-
dents. If your tread is badly
worn, or if your tires have
been damaged, replace them.
CAUTION
Warm tires normally exceed
recommended cold tire pres-
sures by 4 to 6 psi (28 to 41
kPa). Do not release air from
warm tires to adjust the pres-
sure or the tires will be under-
inflated.
Be sure to reinstall the tire
inflation valve caps. Without
the valve cap, dirt or moisture
could get into the valve core
and cause air leakage. If a
valve cap is missing, install a
new one as soon as possible.
