sound and the hazard warning lights
will blink continuously if any of the
following occurs:
- A door is opened without using theremote key or smart key.
- The trunk is opened without using the remote key or smart key.
- The engine hood is opened.
The alarm continues for 30 seconds, then the system resets. To turn off
the alarm, unlock the doors with
the remote key or smart key.

cally sets 30 seconds after you lock

tem to activate, you must lock the
doors and the trunk from outside the

smart key in your possession.
The hazard warning lights will blink

hood without using the remote key or
smart key will cause the alarm to
activate.

the hood, the trunk, or any door is
not fully closed. If the system will not
set, check the hood, the trunk, or the
doors are fully closed.

sengers have left the vehicle. If the
remaining passenger leaves the
vehicle when the system is armed,
the alarm will be activated.

doors by using the mechanical key
and place the ignition switch in the
ON position (for remote key) or start
the engine (for smart key) by direct-

What to do in an emergency

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, charg-
ers, 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 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 of driving.
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.
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.
NOTICE
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.
