If your temperature gauge indicates
overheating, you experience a loss of
power, or hear loud pinging or knocking,
the engine may be overheating. If this
happens, you should:
1. Pull off the road and stop as soon as it
is safe to do so.
2. Shift the gear to P (Park) and set the
parking brake. If the air conditioning is
ON, turn it OFF.
3. If engine coolant is running out under
the vehicle or steam is coming out
from the hood, stop the engine. Do
not open the hood until the coolant
has stopped running or the steaming
has stopped. If there is no visible
loss of engine coolant and no steam,
leave the engine running and check
to be sure the engine cooling fan is
operating. If the fan is not running,
turn the engine off.
WARNING
While the engine is running,
keep hands, clothing and tools
away from the moving parts
such as the cooling fan and
drive belt to prevent serious
injury.
4. Check for coolant leaking from the
radiator, hoses or under the vehicle. (If
the air conditioning had been in use, it
is normal for cold water to be draining
from it when you stop.)
5. If engine coolant is leaking out, stop
the engine immediately and call the
nearest authorized retailer of Genesis
Branded products for assistance.
WARNING
Never remove the engine
coolant cap and/or liquid-
cooled intercooler coolant
cap or the drain plug while the
engine and radiator are hot.Hot coolant and steam may blow out
under pressure, causing serious injury.
Turn the engine off and wait until the
engine cools down. Use extreme care
when removing the radiant cap or
coolant cap. Wrap a thick towel around
it, and turn it counterclockwise slowly
to the first stop. Step back while the
pressure is released from the cooling
system. When you are sure all the
pressure has been released, press down
on the cap, using a thick towel, and
continue turning counterclockwise to
remove it.
6. If you cannot find the cause of the
overheating, wait until the engine
temperature has returned to normal.
Then, if coolant has been lost,
carefully add coolant to the reservoir
to bring the fluid level in the reservoir
up to the halfway mark.
7. Proceed with caution, keeping alert
for further signs of overheating. If
overheating happens again, call an
authorized retailer of Genesis Branded
products for assistance.
CAUTION
• Serious loss of coolant indicates a
leak in the cooling system and should
be checked as soon as possible by
an authorized retailer of Genesis
Branded products.
• When the engine overheats from
low engine coolant, suddenly
adding engine coolant may cause
cracks in the engine. To prevent
damage, add engine coolant slowly
in small quantities. It may require
several refilling cycles to properly
fill the engine cooling system. If
necessary, an authorized retailer of
Genesis Branded products should be
consulted to perform this task.

Tire Pressure Monitoring System
WARNING
Over-inflation or under-inflation can
reduce tire life, adversely affect vehicle
handling, and lead to sudden tire failure
that may cause loss of vehicle control
resulting in an accident.
Each tire, including the spare (if
provided), should be checked monthly
when cold and inflated to the inflation
pressure recommended by the vehicle
manufacturer 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
determine the proper tire inflation
pressure for those tires.)
As an added safety feature, your
vehicle has been equipped with a tire
pressure monitoring system (TPMS)
that illuminates a low tire pressure
telltale when one or more of your tires is
significantly under-inflated. Accordingly,
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 handling 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 operating
properly. The TPMS malfunction
indicator is combined with the low
tire pressure telltale. When the system
detects a malfunction, the telltale will
flash for approximately one minute and
then remain continuously illuminated.
This sequence will continue upon
subsequent vehicle start-ups as long as
the malfunction exists.
When the malfunction indicator is
illuminated, the system may not be able
to detect or signal low tire pressure as
intended. TPMS malfunctions 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.
NOTICE
If any of the below happens, have
the system checked by an authorized
retailer of Genesis Branded products.
1. The Low Tire Pressure Telltale/ TPMS
Malfunction Indicator does not
illuminate for 3 seconds when the
Engine Start/Stop button is pressed
to the ON position or when the
engine is running.
2. The TPMS Malfunction Indicator
remains illuminated after blinking for
approximately 1 minute.
3. The Low Tire Pressure Position
Telltale remains illuminated.

Emergency Situations
Low Tire Pressure
Warning Light
Low Tire Pressure Position and
Tire Pressure Telltale
ORS081029LORS081029L
When the tire pressure monitoring
system warning indicators are
illuminated and a warning message
displayed on the cluster LCD display,
one or more of your tires is significantly
under-inflated. The Low Tire Pressure
Position Telltale will indicate which
tire is significantly underinflated by
illuminating the corresponding position
light.
If either telltale illuminates, immediately
reduce your speed, avoid hard cornering
and anticipate increased stopping
distances. You should stop and check
your tires as soon as possible. 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 service station or
if the tire cannot hold the newly added
air, replace the low pressure tire with the
spare tire.
The Low Tire Pressure LCD position
indicator will remain on and the TPMS
Malfunction Indicator may blink for one
minute and then remain illuminated until
you have the low pressure tire repaired
and replaced 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 pressure
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.
WARNING
Low pressure damage
Significantly low tire pressure makes
the vehicle unstable and can contribute
to loss of vehicle control and increased
braking distances.
Continued driving on low pressure tires
can cause the tires to overheat and fail.

8-12
Emergency Situations
If the indicators do not extinguish after
a few minutes, have visit an authorized
retailer of Genesis Branded products.
Each wheel is equipped with a tire
pressure sensor mounted inside the tire
behind the valve stem (except for the
spare tire). You must use TPMS specific
wheels. It is recommended that you
always have your tires serviced by an
authorized retailer of Genesis Branded
products.
You may not be able to identify a tire
with low pressure by simply looking at it.
Always use a good quality tire pressure
gauge to measure. Please note that a tire
that is hot (from being driven) will have a
higher pressure measurement than a tire
that is cold.
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.
Allow the tire to cool before measuring
the inflation pressure. Always be sure
the tire is cold before inflating to the
recommended pressure.
WARNING
• The TPMS cannot alert you to severe
and sudden tire damage caused by
external factors such as nails or road
debris.
• If you feel any vehicle instability,
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 Pressure Monitoring System
(TPMS) components may interfere
with the system’s ability to warn the
driver of low tire pressure conditions
and/or TPMS malfunctions. Tampering
with, modifying, or disabling the Tire
Pressure Monitoring System (TPMS)
components may void the warranty for
that portion of the vehicle.
WARNING
This device complies with Part 15 of the
FCC rules.

CAUTION
Your vehicle has metric threads on the
studs and wheel bolts. Make certain
during tire changing that the same bolts
that were removed are reinstalled. If
you have to replace your wheel bolts
make sure they have metric threads to
avoid damaging the studs and ensure
the wheel is properly secured to the
hub. Consult an authorized retailer
of Genesis Branded products for
assistance.
If any of the equipment such as the jack,
wheel bolts, studs, or other equipment
is damaged or in poor condition, do not
attempt to change the tire and call for
assistance.

The Tire Mobility Kit is a temporary fix to
the tire and the tire should be inspected
by an authorized retailer of Genesis
Branded products or the equivalent
approved for your vehicle as soon as
possible.
CAUTION
When two or more tires are flat, do not
use the tire mobility kit because the
sealant provided with the Tire Mobility
Kit must be used for only one flat tire.
WARNING
Do not use the Tire Mobility Kit to repair
punctures in the tire walls. This can
result in an accident due to tire failure.
WARNING
Have your tire repaired as soon as
possible. The tire may lose air pressure
at any time after inflating with the Tire
Mobility Kit.
Introduction
With the Tire Mobility Kit you stay mobile
even after experiencing a tire puncture.
The compressor and sealing compound
system effectively and comfortably seals
most punctures in a passenger vehicle
tire caused by nails or similar objects and
reinflates the tire.
After you ensure that the tire is properly
sealed you can drive cautiously on the
tire (distance up to 120 miles (200 km))
at a max. speed of 50 mph (80 km/h) in
order to reach a service station or tire
dealer for the tire replacement.
It is possible that some tires, especially
with larger punctures or damage to the
sidewall, cannot be sealed completely.
Air pressure loss in the tire may adversely
affect tire performance.
For this reason, you should avoid abrupt
steering or other driving maneuvers,
especially if the vehicle is heavily loaded
or if a trailer is in use.
The Tire Mobility Kit is not designed
or intended as a permanent tire repair
method and is to be used for one tire
only.
This instruction shows you step by step
how to temporarily seal the puncture
simply and reliably.
Read the section “Notes on the safe use
of the Tire Mobility Kit”.
WARNING
Do not use the TMK if a tire is severely
damaged by driving run flat or with
insufficient air pressure.
Only punctured areas located within the
tread region of the tire can be sealed
using the TMK.
