TPMS (Tire pressure monitoring
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
Front Left sensor fails, the TPMS mal-
function indicator turns on, but if Front
Right, Rear Left, or Rear Right tire is 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
may turn on and the Low Tire Pressure
telltale may turn off after restarting and
about 20 minutes of continuous driving
before you have the low-pressure tire
repaired and replaced on the vehicle.WARNING - Low pressure
damage
Significantly low tire pressure makes
the vehicle unstable and can contrib-
ute to loss of vehicle control and
increased braking distances.
Continued driving on low pressure
tires can cause the tires to overheat
and fail.
CAUTION - Changing tem-
peratures
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.

under-inflated, the low tire pressure tell-
tale 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 moving around electric power
supply cable or radio transmitter
such as police stations, govern-
ment and public offices, broad-
casting stations, military installa-
tions, airports, or transmitting
tower, etc. which can interfere with
normal operation of the Tire Pres-
sure Monitoring System (TPMS).
o The TPMS malfunction indicator
may be illuminated if snow chains
or some electronic devices, such
as notebook computer, 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 ve-
hicle that is also equipped with
TPMS. In rare cases, this may
temporarily delay the TPMS mal-
function 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.
NOTE:
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 recommended that you always
have your tires serviced by an autho-
rized Hyundai dealer as soon as pos-
sible.
After you replace the low pressure tire
with the temporary spare tire, the TPMS
malfunction indicator may illuminate
after restarting and about 20 minutes of
continuous driving.
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 be soon extinguished.
If the low pressure and TPMS malfunc-
tion indicators are not extinguished af-
ter 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.

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 interfer-
ence received, including interference
that may cause undesired operation. WARNING - TPMS
o The TPMS cannot alert you to se-
vere and sudden tire damage
caused by external factors such as
nails or road debris.
o If you feel any vehicle instability,
immediately take your foot off the
accelerator, apply the brakes
gradually and with light force, and
slowly move to a safe position off
the road.
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. 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 (1.6
km) during that 3 hour period). Allow the
tire to cool before measuring the infla-
tion pressure.
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 (1.6 km) in that 3 hour
period.
CAUTION:
Do not use any tire sealant if your
vehicle is equipped with a Tire Pres-
sure Monitoring System. The liquid
sealant can damage the tire pressure
sensors.
In order for the system to correctly
monitor tires for under-inflation,
there should be a total of exactly 4
sensors fitted to each of the four
driven wheel positions.
!
WARNING - Protecting TPMS
Tampering with, modifying, or dis-
abling the Tire Pressure Monitoring
System (TPMS) components may in-
terfere with the system's ability to warn
the driver of low tire pressure condi-
tions and/or TPMS malfunctions. There should be no other sensors in
the vehicle including spare tire po-
sition since this could cause the
system to monitor the wrong sen-
sors.

EMISSION CONTROL SYSTEMS2
EMISSION CONTROL SYSTEM
H010D01A-AAT3. Exhaust Emission Control SystemThe Exhaust Emission Control System is a
highly effective system which controls exhaust
emissions while maintaining good vehicle
performace.
H010B01A-AAT1. Crankcase Emission Control
SystemThe positive crankcase ventilation system is
employed to prevent air pollution caused by
blow-by gases being emitted from the crank-
case. This system supplies filtered air to the
crankcase through the air intake hose. Inside
the crankcase, the fresh air mixes with blow-by
gases, which then pass through the PCV valve
and into the induction system.
H010A02O-AATYour Hyundai is equipped with an emission
control system to meet all requirements of the
U.S. Environmental Protection Agency or Cali-
fornia Air Resources Board.
There are three emission control systems which
are as follows.
(1) Crankcase emission control system
(2) Evaporative emission control system
(3) Exhaust emission control system
In order to assure the proper function of the
emission control systems, it is recommended
that you have your car inspected and main-
tained by an authorized Hyundai dealer in ac-
cordance with the maintenance schedule in this
manual.
Caution for the Inspection and Maintenance
Test (V6 Vehicle with Traction Control Sys-
tem)
o To prevent the vehicle from misfiring
during dynamometer testing, discon-
nect the ABS connector in the engine
compartment. (2.7 V6 only)
o For more information, see shop manual
(Wheel Speed Sensor).
o After dynamometer testing is completed,
erase the ABS/TCS DTC (Diagnotic
Trouble Code) with a GST (Generic Scan
Tool) or Hi-Scan Pro.
CanisterFuel vapors generated inside the fuel tank are
absorbed and stored in the canister. When the
engine is running, the fuel vapors absorbed in
the canister are drawn into the induction system
through the purge control solenoid valve.Purge Control Solenoid Valve (PCSV)The purge control solenoid valve is controlled
by the Engine Control Module (ECM); when the
engine coolant temperature is low during idling,
the PCSV closes so that evaporated fuel is not
taken into the engine. After the engine warms-
up during ordinary driving, the PCSV opens to
introduce evaporated fuel to the engine.
H010C01S-AAT2. Evaporative Emission Control (Includ-
ing ORVR: Onboard Refueling Vapor
Recovery) SystemThe Evaporative Emission Control System is
designed to prevent fuel vapors from escaping
into the atmosphere.
(The ORVR system is designed to allow the
vapors from the fuel tank to be loaded into a
canister while refueling at the gas station, pre-
venting the escape of fuel vapors into the
atmosphere.)
