TPMS Malfunction Indicator
The TPMS Malfunction Indicator will
illuminate after it blinks for approxi-
mately one minute when there is a
problem with the Tire Pressure
Monitoring System.
Have the system checked by an
authorized HYUNDAI dealer as soon
as possible. If there is a malfunction with the
TPMS, the individual tire pres-
sures in the cluster LCD display
will not be available. Have the sys-
tem checked by an authorized
HYUNDAI dealer as soon as possi-
ble.
NOTICE
In winter or cold weather, the
Low Tire Pressure Telltale maybe illuminated if the tire pres-sure was adjusted to the recom-mended tire inflation pressure
in warm weather. It does not
mean your TPMS is malfunc-tioning because the decreased
temperature leads to a propor-
tional 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 inflationpressure and adjust the tires tothe recommended tire inflation
pressure.
CAUTION
Low pressure damage
Significantly low tire pressure
makes the vehicle unstable and
can contribute to loss of vehicle
control and increased brakingdistances.
Continued driving on low pres- sure tires can cause the tires to
overheat and fail.
WARNING

6-16
What to do in an emergency
You may not be able identify a tire
with low pressure by simply looking
at it. Always use a good quality tirepressure gage to measure the tire's
inflation pressure. Please note that a
tire that is hot (from being driven) will
have a higher pressure measure-ment than a tire that is cold.
A cold tire means the vehicle has
been sitting for 3 hours and driven forless than 1.6 km (1 mile) in that 3
hour period.
Allow the tire to cool before measur-
ing the inflation pressure. Always be
sure the tire is cold before inflating to
the recommended pressure.Information
This device complies with Industry
Canada RSS-210 standard.
Operation is subject to the following
three conditions:
1. This device may not cause harmful interference.
2. This device must accept any inter- ference received, including interfer-
ence that may cause undesired
operation.
3. Changes or modifications not expressly approved by the party
responsible for compliance could
void the user 's authority to operate
the equipment.i
The TPMS cannot alert you to
severe and sudden tire dam-
age caused by external fac-
tors such as nails or roaddebris.
If you feel any vehicle instabil-
ity, immediately take your foot
off the accelerator, apply the
brakes gradually with light
force, and slowly move to a
safe position off the road.
WARNING
Tampering with, modifying, or
disabling the Tire PressureMonitoring System (TPMS)
components may interfere withthe system's ability to warn the
driver of low tire pressure con-
ditions and/or TPMS malfunc-
tions. Tampering with, modify-
ing, or disabling the TirePressure Monitoring System
(TPMS) components may void
the warranty for that portion of
the vehicle.

OFE068014 One sealant bottle for one tire
When two or more tires are flat, do not use the tire mobility kit
because the supported one
sealant of Tire Mobility Kit is
only used for one flat tire.
CAUTION
Tire wall
Do not use the Tire Mobility Kit to repair punctures in the tire
walls. This can result in an acci-
dent due to tire failure.
WARNING
Temporary fix
Have your tire repaired as soon
as possible. The tire may lose
air pressure at any time after
inflating with the Tire MobilityKit.

What to do in an emergency
Connectors, cable and connection hose are stored in the compressorhousing.
Strictly follow the specified sequence,
otherwise the sealant may escape
under high pressure.Using the Tire Mobility Kit
1. Shake the sealant bottle (2).2. Connect the filling hose (3) to the
sealant bottle (2) in the direction of(A) and connect the sealant bottleto the compressor (5) in the direc-tion of (B).
3. Ensure that the compressor is switched OFF.
Do not use the tire sealant after
the sealant has expired (i.e.
pasted the expiration date on
the sealant container). This can
increase the risk of tire failure.
WARNING
Keep out of reach of children.
Avoid contact with eyes.
Do not swallow.
WARNING
Detach the speed restriction
label (1) from the sealant bottle
(2), and place it in a highly visi-
ble place inside the vehicle

4. Unscrew the valve cap from thevalve of the defective wheel and
screw the filling hose (3) of the
sealant bottle onto the valve. 5. Plug the compressor power cord
(4) into the vehicle power outlet.
6. With the vehicle ON ( indica- tor ON), switch on the compressor
and let it run for approximately
5~7 minutes to fill the sealant up
to proper pressure. (refer to the
Tire and Wheels, chapter 8). Theinflation pressure of the tire after
filling is unimportant and will be
checked/corrected later.
Be careful not to overinflate the
tire and stay away from the tirewhen filling it. 7. Switch off the compressor.
8. Detach the hoses from the sealant
bottle connector and from the tire
valve.
Return the Tire Mobility Kit to its stor-
age location in the vehicle.
OFE068015OFE068016
Securely install the sealant fill-
ing hose to the valve. If not,
sealant may flow backward,
possibly clogging the filling
hose.
CAUTION
Do not attempt to drive your
vehicle if the tire pressure is
below 200 kpa (29 psi). Thiscould result in an accident due
to sudden tire failure.
CAUTION
Do not the filling leave your
vehicle running in a poorly ven-
tilated area for extended peri-
ods of time. Carbon monoxide
poisoning and suffocation can
occur.

Maintenance
Owner Maintenance Schedule
When you stop for fuel:
• Check for both fuel cell stack andDevice cooling coolant level in
coolant reservoir.
Check the windshield washer fluid level.
Look for low or under-inflated tires.
While operating your vehicle:
Check for vibrations in the steering wheel. Notice if there is any
increased steering effort or loose-
ness in the steering wheel, or
change in its straight-ahead posi-tion.
Notice if your vehicle constantly turns slightly or "pulls" to one side
when traveling on smooth, levelroad.
When stopping, listen and check for unusual sounds, pulling to one
side, increased brake pedal travel
or "hard-to-push" brake pedal.
If any slipping or changes in the operation of your reduction gear
occurs, check the reduction gear
fluid level.
Check the reduction gear P (Park) function.
Check the parking brake.
Check for fluid leaks under your vehicle (water dripping from the air
conditioning system during or after
use is normal).
At least monthly:
Check coolant level in the coolantreservoir.
Check the operation of all exterior lights, including the brake lights,
turn signals and hazard warning
flashers.
Check the inflation pressures of all tires that are worn, show uneven
wear, or are damaged.
Check for loose wheel lug nuts.
At least twice a year: (i.e., every Spring and Fall)
Check radiator, heater and air con- ditioning hoses for leaks or dam-
age.
Check windshield washer spray and wiper operation. Clean wiper
blades with clean cloth dampened
with washer fluid.
Check headlamp alignment.
Check the seat belts for wear and function.
Be careful when checking the
coolant level when the fuel cell
power module is hot. Scalding
hot coolant and steam may
blow out under pressure. This
could cause burns or other seri-
ous injury.

For mixing percentage, refer to the
following table:Information
If in doubt about the mix ratio, a 50%
water and 50% antifreeze mix is the
easiest to mix together as it will be the
same quantity of each. It is suitable to
use for most temperature ranges of
-35°C (-31°F) and higher.
