Immobilizer system (if equipped)
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.
Place the ignition switch to the LOCK/
OFF position, then place the ignition
switch 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.

8-13
TPMS (Tire Pressure
Monitoring System)
malfunction indicator
The TPMS Malfunction Indicator
will illuminate after it blinks for
approximately one minute when there
is a problem with the Tire Pressure
Monitoring System.
We recommend that you have the
system checked by an authorized
HYUNDAI dealer as soon as possible.
NOTICE
If there is a malfunction with the TPMS,
the Low Tire Pressure Position Indicator
will not be displayed even though the
vehicle has an under-inflated tire.
NOTICE
The TPMS Malfunction Indicator may
illuminate after blinking for one minute
if the vehicle is near electric power
supply cables or radio transmitters
such as police stations, government
and public offices, broadcasting
stations, military installations, airports,
transmitting towers, etc.
Additionally, the TPMS Malfunction
Indicator may illuminate if snow chains
are used or electronic devices such as
computers, chargers, remote starters,
navigation, etc. This may interfere with
normal operation of the TPMS.
Changing a tire with TPMS
If you have a flat tire, the Low Tire
Pressure and Position indicators will
come on. We recommend that you have
the flat tire repaired by an authorized
HYUNDAI dealer as soon as possible or
replace the flat tire with the spare tire.
NOTICE
It is recommended that you do not
use a puncture-repairing agent not
approved by HYUNDAI dealer or the
equivalent specified for your vehicle to
repair and/or inflate a low pressure tire.
Tire sealant not approved by HYUNDAI
dealer or the equivalent specified for
your vehicle may damage the tire
pressure sensor.
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 Indicator 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 10 minutes.
Once the original tire equipped with
a tire pressure monitoring sensor is
reinflated to the recommended pressure
and reinstalled on the vehicle, the
Low Tire Pressure Indicator and TPMS
Malfunction Indicator will go off within a
few minutes of driving.
If the indicators do not extinguish after
a few minutes, we recommend that you
contact 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.

Emergency situations
8-20
9. With the vehicle ON
( indicator ON), switch on
the compressor and let it run for
approximately 5~7 minutes to fill
the sealant up to proper pressure.
(Refer to “Tire and Wheels” section
in chapter2). The inflation pressure of
the tire after filling is unimportant and
will be checked/corrected later.
Be careful not to overinflate the tire
and stay away from the tire when
filling it.
CAUTION
Do not attempt to drive your vehicle if
the tire pressure is below 200 kpa (29
psi). This could result in an accident due
to sudden tire failure.
10.
Swit

ch off the compressor.
11.
Detach the hoses fr

om the sealant
bottle connector and from the tire
valve.
Return the Tire Mobility Kit to its storage
location in the vehicle.
WARNING
Do not leave your vehicle running in
a poorly ventilated area for extended
periods of time. Carbon monoxide
poisoning and suffocation can occur.
Distributing the sealant
OOSH079022L
12. Immediat ely drive approximately 4~6
miles (7~10 km or about 10 minutes)
to evenly distribute the sealant in the
tire.
Do not exceed a speed of 50 mph (80
km/h). If possible, do not fall below a
speed of 12 mph (20 km/h).
While driving, if you experience any
unusual vibration, ride disturbance or
noise, reduce your speed and drive with
caution until you can safely pull off of the
side of the road.
Call for road side service or towing.

Maintenance
9-34
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 in. (1.6 mm) 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.
