This label also tells you the maximum
weights that can be supported by the
front and rear axles, called Gross Axle
Weight Rating (GAWR). To find out the
actual loads on your front and rear
axles, you need to go to a weigh station
and weigh your vehicle. Your dealer can
help you with this. Be sure to spread out
your load equally on the left and right
sides of the centerline.
WARNING:
o Never exceed the GVWR for your
vehicle, the GAWR for either the
front or rear axle and vehicle ca-
pacity weight. Exceeding these rat-
ings can cause an accident or
vehicle damage. You can calcu-
late the weight of your load by
weighing the items (or people)
before putting them in the vehicle.
Be careful not to overload your
vehicle. WARNING:
o Do not load your vehicle any
heavier than the GVWR, either the
maximum front or rear GAWR and
vehicle capacity weight. If you do,
parts, including tires on your ve-
hicle can break, and it can change
the way your vehicle handles and
braking ability. This could cause
you to lose control and crash.
Also, overloading can shorten the
life of your vehicle.
C190G03JM-AATCertification Label
The certification label is located on the
driver's side center pillar outer panel.
The label shows the maximum allow-
able weight of the fully loaded vehicle.
This is called the GVWR (Gross Ve-
hicle Weight Rating). The GVWR in-
cludes the weight of the vehicle, all
occupants, fuel and cargo.

WARNING:
Items you carry inside your vehicle
can strike and injure people in a
sudden stop or turn, or in a crash.
o Put things in the cargo area of
your vehicle. Try to spread the
weight evenly.
o Never stack items, like suitcases,
inside the vehicle above the tops
of the seats.
o Do not leave an unsecured child
restraint in your vehicle.
o When you carry something inside
the vehicle, secure it.
o Do not drive with a seat folded
down unless necessary. NOTE:
o Overloading your vehicle may
cause damage. Repairs would not
be covered by your warranty. Do
not overload your vehicle.
o Using heavier suspension com-
ponents to get added durability
might not change your weight rat-
ings. Ask your dealer to help you
load your vehicle the right way.
The label will help you decide how much
cargo and installed equipment your
vehicle can carry.
If you carry items inside your vehicle –
like suitcases, tools, packages, or any-
thing else – they move as fast as the
vehicle goes. If you have to stop or turn
quickly, or if there is a crash, the items
will keep going and can cause an injury
if they strike the driver or a passenger.
!
WARNING:
o Overloading your vehicle can
cause heat buildup in your
vehicle's tires and possible tire
failure that could lead to a crash.
o Overloading your vehicle can
cause increased stopping dis-
tances that could lead to a crash.
o A crash resulting from poor han-
dling vehicle damage, tire failure,
or increased stopping distances
could result in serious injury or
death.

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.
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.

CHANGING A FLAT TIRE
IF YOU HAVE A FLAT TIRE
D060A01A-AATThe procedure described on the follow-
ing pages can be used to rotate tires as
well as to change a flat tire. When
preparing to change a flat tire, check to
be sure the gear selector lever is in "P"
(automatic transaxle) or reverse gear
(manual transaxle) and that the parking
brake is set, then:
D050A01A-AATIf a tire goes flat while you are driving:
1. Take your foot off the accelerator pedal
and let the car slow down while driving
straight ahead. Do not apply the brakes
immediately or attempt to pull off the
road as this may cause a loss of
control. When the car has slowed to
such a speed that it is safe to do so,
brake carefully and pull off the road.
Drive off the road as far as possible
and park on firm, level ground. If you
are on a divided highway, do not park
in the median area between the two
traffic lanes.
2. When the car is stopped, turn on your
emergency hazard flashers, set the
parking brake and put the transaxle in
"P" (automatic) or reverse (manual
transaxle).
3. Have all passengers get out of the car.
Be sure they all get out on the side of
the car that is away from traffic.
4. Change the tire according to the in-
structions provided as follows.
