Immobilizer system
The immobilizer system helps protect
your vehicle from theft. If an improperly
coded key (or other device) is used, the
engine’s fuel system is disabled.
When the Engine Start/Stop button
is pressed to the ON position, the
immobilizer system indicator should
come on briefly, then go off. If the
indicator starts to blink, the system does
not recognize the coding of the key.
Press the Engine Start/Stop button to
the OFF position, then press the Engine
Start/Stop button to the ON position
again.
The system may not recognize your
key’s coding if another immobilizer key
or other metal object (i.e., key chain) is
near the key. The engine may not start
because the metal may interrupt the
transponder signal from transmitting
normally.
If the system repeatedly does not
recognize the coding of the key, it is
recommended that you contact your
HYUNDAI dealer.
Do not attempt to alter this system
or add other devices to it. Electrical
problems could result that may make
your vehicle inoperable. WARNING
In order to prevent theft of your
vehicle, do not leave spare keys
anywhere in your vehicle. Your
immobilizer password is a customer
unique password and should be kept
confidential.
NOTICE
The transponder in your key is an
important part of the immobilizer
system. It is designed to give years
of trouble-free service, however you
should avoid exposure to moisture,
static electricity and rough handling.
Immobilizer system malfunction could
occur.

Low tire pressure
warning light
Low tire pressure position and
tire pressure telltale
ONX4E040019
When the tire pressure monitoring
system warning indicators are
illuminated and a warning message
displayed on the cluster LCD display,
one or more of your tires is significantly
under-inflated. The Low Tire Pressure
Position Telltale will indicate which
tire is significantly underinflated by
illuminating the corresponding position
light.
If either telltale illuminates, immediately
reduce your speed, avoid hard cornering
and anticipate increased stopping
distances. You should stop and check
your tires as soon as possible. Inflate the
tires to the proper pressure as indicated
on the vehicle’s placard or tire inflation
pressure label located on the driver’s
side center 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 10 minutes at
speed above 15.5 mph (25 km/h)) until
you have the low pressure tire repaired
and replaced on the vehicle.
CAUTION
In winter or cold weather, the Low Tire
Pressure Telltale may be illuminated if
the tire pressure was adjusted to the
recommended tire inflation pressure
in warm weather. It does not mean
your TPMS is malfunctioning because
the decreased temperature 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.
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 pressure tires
can cause the tires to overheat and fail.

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 serviced by an
authorized HYUNDAI dealer.
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 measuring
the inflation pressure. Always be sure
the tire is cold before inflating to the
recommended pressure.
WARNING
• The TPMS cannot alert you to severe
and sudden tire damage caused by
external factors such as nails or road
debris.
• If you feel any vehicle instability,
immediately take your foot off
the accelerator, apply the brakes
gradually with light force, and slowly
move to a safe position off the road.
WARNING
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 conditions
and/or TPMS malfunctions. Tampering
with, modifying, or disabling the Tire
Pressure Monitoring System (TPMS)
components may void the warranty for
that portion of the vehicle.
Information
This device complies with Part 15 of the
FCC rules.
Operation is subject to the following three
conditions:
1. This device may not cause harmful
interference.
2. This device must accept any
interference received, including
interference that may cause undesired
operation.
3. Changes or modifications not expressly
approved by the party responsible
for compliance could void the user’s
authority to operate the equipment.

Wheel alignment and tire
balance
The wheels on your vehicle were
aligned and balanced carefully at the
factory to give you the longest tire
life and best overall performance.
In most cases, you will not need to
have your wheels aligned again.
However, if you notice unusual tire
wear or your vehicle pulling one way
or the other, the alignment may need
to be reset.
If you notice your vehicle vibrating
when driving on a smooth road, your
wheels may need to be rebalanced.
NOTICE
Incorrect wheel weights can damage
your vehicle’s aluminum wheels. Use
only approved wheel weights.
Tire replacement
Tread wear indicatorTread wear indicator
OHI078080
If the tire is worn evenly, a tread
wear indicator will appear as a solid
band across the tread. This shows
there is less than 1/16 inch (1.6mm) of
tread left on the tire. Replace the tire
when this happens.
Do not wait for the band to appear
across the entire tread before
replacing the tire.
WARNING
To reduce the risk of DEATH or
SERIOUS INJURY:
• Replace tires that are worn, show
uneven wear, or are damaged.
Worn tires can cause loss of
braking effectiveness, steering
control, and traction.
• Always replace tires with the
same size as each tire that was
originally supplied with this
vehicle. Using tires and wheels
other than the recommended
sizes could cause unusual
handling characteristics, poor
vehicle control, or negatively
affect your vehicle’s Anti-Lock
Brake System (ABS) resulting in a
serious accident.
• When replacing tires (or wheels),
it is recommended to replace
the two front or two rear tires (or
wheels) as a pair. Replacing just
one tire can seriously affect your
vehicle’s handling.
• Tires degrade over time, even
when they are not being used.
Regardless of the remaining
tread, HYUNDAI recommends
that tires be replaced after six (6)
years of normal service.
• Heat caused by hot climates or
frequent high loading conditions
can accelerate the aging process.
Failure to follow this warning
may cause sudden tire failure,
which could lead to a loss of
vehicle control resulting in an
accident.
