Low tire pressure telltale
When the tire pressure monitoring sys-
tem warning telltale is illuminated, one
or more of your tires is significantly
under-inflated.
Immediately 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 vehicle’s
placard or tire inflation pressure label
located on the driver’s side center pillar
outer panel. If you cannot reach a ser-
vice station or if the tire cannot hold the
newly added air, replace the low pres-
sure tire with the temporary spare tire.
Then the TPMS malfunction indicator
or the Low Tire Pressure telltale may
turn on after restarting and about 20
minutes of continuous driving before
you have the low-pressure tire repaired
and reinstalled 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 pres-
sure 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.
Always check your tire inflation pres-
sures when the tires are cold, before
you have driven on them.WARNING - Low pressure
Significantly low tire pressure makes
the vehicle unstable and can contrib-
ute to loss of vehicle control and
increased braking distances. Contin-
ued driving on low pressure tires will
cause the tires to overheat and fail.
TPMS (Tire pressure moni-
toring system) malfunction
indicator
The TPMS malfunction indicator turns
on and stays on when there is a problem
with the Tire Pressure Monitoring Sys-
tem. If 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, e.g. if
the Front Left sensor fails, the TPMS
malfunction indicator turns on, but if the
Front Right, Rear Left, or Rear Right tire
is under-inflated, the low tire pressure
telltale may turn on at the same time as
the TPMS malfunction indicator.

WHAT TO DO IN AN EMERGENCY

Have the system checked by an autho-
rized Hyundai dealer as soon as pos-
sible to determine the cause of the
problem.
NOTE:
o The TPMS malfunction indicator
may be illuminated if the vehicle
is operated in areas close to elec-
tric power supply cables or radio
transmitters such as near police
stations, government and public
offices, broadcasting stations,
military installations, airports, or
transmitting towers, etc. which can
interfere with normal operation of
the Tire Pressure Monitoring Sys-
tem (TPMS).
o The TPMS malfunction indicator
may be illuminated if snow chains
or some electronic devices, such
as notebook computers, are used
in the vehicle. This can interfere
with normal operation of the Tire
Pressure Monitoring System
(TPMS).o If there is a failed tire sensor, it is
possible for the TPMS to tempo-
rarily learn a replacement sensor
if closely driven to another vehicle
that is also equipped with TPMS.
In rare cases, this may tempo-
rarily delay the TPMS malfunction
indicator from turning on.
Changing a tire with TPMS
If you have a flat tire, the Low Tire
Pressure telltale will turn on. Have the
flat tire repaired by an authorized Hyundai
dealer as soon as possible or replace
the flat tire with the temporary spare
tire. NEVER use a puncture-repairing
agent to repair and/or inflate a low
pressure tire. If used, you will have to
replace the tire pressure sensor.
Each wheel is equipped with a tire
pressure sensor mounted inside the tire
behind the valve stem. You must use
TPMS specific wheels. It is recom-
mended that you always have your tires
serviced by an authorized Hyundai
dealer.After you replace the low pressure tire
with the spare tire, the TPMS malfunc-
tion indicator or the Low Tire Pressure
telltale may illuminate after restarting
and driving for about 20 minutes.
Once the low pressure tire is re-inflated
to the recommended pressure and in-
stalled on the vehicle, the TPMS mal-
function indicator and the low tire pres-
sure telltale will extinguish. If the low
pressure and TPMS malfunction indi-
cators are not extinguished after about
20 minutes of continuous driving, please
visit an authorized Hyundai dealer.
You may not be able to 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 pres-
sure measurement than a tire that is
cold (from sitting stationary for at least
3 hours and driven less than 1 mile
during that 3 hour period). Allow the tire
to cool before measuring the inflation
pressure.

38WHAT TO DO IN AN EMERGENCY
!
!!
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 mile in that 3 hour period.
NOTE:
o 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 sensors.
o In order for the system to correctly
monitor tires for under-inflation,
there should be a total of 4 sen-
sors, one fitted to each of the four
wheel positions. There should be
no other sensors in the vehicle
including for the spare tire. This
could cause the system to moni-
tor the wrong sensor. WARNING - TPMS
o The TPMS cannot alert you to se-
vere and sudden tire damage
caused by external factors.
o If you feel any vehicle instability,
take your foot off the accelerator
and slowly move to a safe position
off the road.
WARNING:
Tampering with, modifying, or dis-
abling 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 malfunc-
tions. Tampering with, modifying,
or disabling the Tire Pressure Moni-
toring System (TPMS) components
may void the warranty for that por-
tion of the vehicle.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 interfer-
ence that may cause undesired op-
eration.
WARNING:
Changes or modifications not ex-
pressly approved by the party re-
sponsible for compliance could void
the user’s authority to operate the
equipment.
