TIRE PRESSURE MONITORING SYSTEM (TPMS)
ONF048131 C320A01JM-AAT
➀ TPMS Malfunction Indicator
➁ Low Tire Pressure Telltale
Each tire, including the spare (if pro-
vided), should be checked monthly when
cold and inflated to the inflation pres-
sure recommended by the vehicle manu-
facturer on the vehicle placard or tire
inflation pressure label. (If your vehicle
has tires of a different size than the size
indicated on the vehicle placard or tire
inflation pressure label, you should de-
termine the proper tire inflation pres-
sure for those tires.)As an added safety feature, your ve-
hicle has been equipped with a tire
pressure monitoring system (TPMS)
that illuminates a low tire pressure tell-
tale when one or more of your tires is
significantly under-inflated. Accord-
ingly, when the low tire pressure telltale
illuminates, you should stop and check
your tires as soon as possible, and
inflate them to the proper pressure.
Driving on a significantly under-inflated
tire causes the tire to overheat and can
lead to tire failure. Under-inflation also
reduces fuel efficiency and tire tread
life, and may affect the vehicle’s han-
dling and stopping ability.
Please note that the TPMS is not a
substitute for proper tire maintenance,
and it is the driver’s responsibility to
maintain correct tire pressure, even if
under-inflation has not reached the level
to trigger illumination of the TPMS low
tire pressure telltale.Your vehicle has also been equipped
with a TPMS malfunction indicator to
indicate when the system is not operat-
ing properly. The TPMS malfunction
indicator is provided by a separate tell-
tale, which displays the symbol "TPMS"
when illuminated. When the malfunc-
tion indicator is illuminated, the system
may not be able to detect or signal low
tire pressure as intended. TPMS mal-
functions may occur for a variety of
reasons, including the installation of
replacement or alternate tires or wheels
on the vehicle that prevent the TPMS
from functioning properly. Always
check the TPMS malfunction telltale
after replacing one or more tires or
wheels on your vehicle to ensure that
the replacement or alternate tires and
wheels allow the TPMS to continue to
function properly.

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.

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.

4. As the temporary spare tire is spe-
cifically designed for your car, it
should not be used on any other
vehicle.
5. The temporary spare tire should not
be used on any other wheels, nor
should standard tires, snow tires,
wheel covers or trim rings be used
with the temporary spare wheel. If
such use is attempted, damage to
these items or other car components
may occur.
6. The temporary spare tire pressure
should be checked once a month
while the tire is stored.
2. The spare tire should only be used
temporarily and should be returned
to the luggage compartment as soon
as the original tire can be repaired or
replaced.
3. Continuous use at speeds of over 50
mph (80 km/h) is not recommended. Spare Tire Pressure
CAUTION:
o Do not use snow chains with your
temporary spare tire.
o Do not use more than one tempo-
rary spare tire at a time.
o Do not tow a trailer while the tem-
porary spare tire is installed.
!
WARNING:
The temporary spare tire is for emer-
gency use only. Do not operate your
vehicle on this temporary spare at
speeds over 50 mph (80 kmh). The

D060D01A-AAT3. Loosen Wheel Nuts
The wheel nuts should be loosened
slightly before raising the car. To loosen
the nuts, turn the wrench handle coun-
terclockwise. When doing this, be sure
that the socket is seated completely
over the nut so it cannot slip off. For
maximum leverage, position the wrench
so the handle is to the left as shown in
the drawing. Then, while holding the
wrench near the end of the handle, push
down on it with steady pressure. Do not
remove the nuts at this time. Just
loosen them about one-half turn.

D060J02O-AATAfter Changing Wheels
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 correct
pressure. If it is too high, adjust it until Wheel nut tightening torque:

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 possible.
After you have changed wheels, al-
ways secure the flat tire in its place and
return the jack and tools to their proper
storage locations.
IF YOUR VEHICLE MUST BE
TOWEDD080A01O-GATIf your vehicle has to be towed, it should be
done by your Hyundai dealer or a
commercial tow truck service. This will
help assure that your vehicle is not dam-
aged in towing. Also, professionals are
generally aware of local laws governing
towing. In any case, rather than risk damage
to your car, it is suggested that you show
this information to the tow truck operator.
Be sure that a safety chain system is used
and that all local laws are observed.
It is recommended that your vehicle be
towed with a wheel lift and dollies or flatbed
equipment with all the wheels off the
ground.!
CAUTION:
o Your vehicle can be damaged if towed
incorrectly!
o Be sure the transaxle is in neutral.
o When the engine will not start, be sure
the steering is unlocked by placing
the key in the "ACC" position.

CORROSION PREVENTION AND APPEARANCE CARE4
If you find any nicks or scratches in the
paint, use touch-up paint to cover them to
prevent corrosion. To protect the paintwork
of the car against corrosion, you must
clean your Hyundai (at least once a month).
Give special attention to the removal of
salt, mud and other substances on the
underside of the splashboards of the car.
Make sure that the outlets and the under-
side of the doors are open. Paint damage
can be caused by small accumulation of
tar, industrial precipitation, tree resin, in-
sects and bird droppings, when not re-
moved immediately. If water alone is not
strong enough to remove the accumulated
dirt, use a mild car washing solution. Be
sure to rinse the surface after washing to
remove the solution. Never allow the solu-
tion to dry on the painted surfaces. To clean whitewall tires, use a stiff brush or
soapy steel-wool scouring pad.
To clean plastic wheel covers, use a clean
sponge or soft cloth and water.
To clean cast aluminum alloy wheels, use
a mild soap or neutral detergent. Do not
use abrasive cleaners. Protect the bare-
metal surfaces by cleaning, polishing and
waxing. Because aluminum is subject to
corrosion, be sure to give aluminum alloy
wheels special attention in winter. If you
drive on salted roads, clean the wheels
thoroughly afterwards.
After washing, be sure to rinse thoroughly.
If soapy water dries on the finish, streaking
will result.
When the weather is warm and the humidity
low, you may find it necessary to rinse each
section immediately after washing to avoid
streaking.
After rinsing, dry the car using a damp
chamois or soft, absorbent cloth. The
reason for drying the car is to remove water
from the car so it will dry without water
spots. Don't rub, this can damage the finish.
CAUTION:
!
OJB037800
o Water washing in the engine compart-
ment including high pressure water
washing may cause the failure of elec-
trical circuits located in the engine
compartment.
o Never allow water or other liquids to
come in contact with electrical/elec-
tronic components inside the vehicle
as this may damage them.
!
CAUTION:
Do not wash the side windows too close
with high pressure water. Water may
leak through the windows and wet the
interior.
