If your temperature gauge indicates
overheating, you experience a loss
of power, or hear loud pinging or
knocking, the engine may be over-
heating. 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 condi-
tioning is ON, turn it OFF.
3. If engine coolant is running out
under the vehicle or steam is com-
ing 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.4. Check for coolant leaking from the
radiator, hoses or under the vehi-
cle. (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.
IF THE ENGINE OVERHEATS
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 seri-
ous injury.

6. If you cannot find the cause of the
overheating, wait until the engine
temperature has returned to nor-
mal. 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 overheat-
ing. If overheating happens again,
call an authorized retailer of
Genesis Branded products for
assistance.
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.
NOTICE
Your vehicle is
equipped with a pres-
surized coolant
reserve tank. NEVER
remove the radiator
cap, drain plug and heater hose
connector cap (refer to the
below picture) 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 remov-
ing the coolant reserve tank
cap. Wrap a towel or thick rag
around it, and turn it counter-
clockwise slowly to release
some of the pressure from the
system. Step back while the
pressure is released.
When you are sure all the pres-
sure has been released, contin-
ue turning the cap counter-
clockwise to remove it.

What to do in an emergency
Tire Pressure Monitoring
System
Each tire, including the spare (if pro-
vided), should be checked monthly
when cold and inflated to the inflation
pressure recommended by the vehi-
cle manufacturer on the vehicle plac-
ard 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 pres-
sure 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 that illu-
minates a low tire pressure telltale
when one or more of your tires is sig-
nificantly 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 pres-
sure. Driving on a significantly under-
inflated tire causes the tire to over-
heat and can lead to tire failure.
Under-inflation also reduces fuel effi-
ciency 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 mainte-
nance, and it is the driver's responsi-
bility to maintain correct tire pres-
sure, even if under-inflation has not
reached the level to trigger illumina-
tion 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 oper-
ating properly. The TPMS malfunc-
tion 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 continu-
ously 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 pres-
sure as intended. TPMS malfunc-
tions may occur for a variety of rea-
sons, 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 alter-
nate tires and wheels allow the
TPMS to continue to function proper-
ly. 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 con-
trol resulting in an accident.

Indicator
When the tire pressure monitoring
system warning indicators are illumi-
nated and the warning message is
displayed on the cluster LCD display,
one or more of your tires is signifi-
cantly under-inflated. The LCD posi-
tion indicator will indicate which tire
is significantly under-inflated by illu-
minating the corresponding position
light.
If any of your tire pressures are indi-
cated as being low, immediately
reduce your speed, avoid hard cor-
nering, 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 vehi-
cle’s placard or tire inflation pressure
label located on the driver's side cen-
ter 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.

What to do in an emergency
Information
The spare tire is not equipped with a
tire pressure sensor.
In winter or cold weather, the Low
Tire Pressure Telltale may be illu-
minated if the tire pressure was
adjusted to the recommended tire
inflation pressure in warm weath-
er. It does not mean your TPMS is
malfunctioning because the
decreased temperature leads to a
proportional lowering of tire pres-
sure.
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 recommend-
ed tire inflation pressure.
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 retailer of Genesis
Branded products as soon as possi-
ble.
Information
If there is a malfunction with the
TPMS, the individual tire pressures in
the cluster LCD display will not be
available. Have the system checked by
an authorized retailer of Genesis
Branded products as soon as possible.
The TPMS Malfunction Indicator
may illuminate after blinking for
one minute if the vehicle is near
electric power supply cables or
radio transmitters such as police
stations, government and public
offices, broadcasting stations,
military installations, airports,
transmitting towers, etc.
Additionally, the TPMS
Malfunction Indicator may illumi-
nate if snow chains are used or
electronic devices such as com-
puters, chargers, remote starters,
navigation, etc. This may interfere
with normal operation of the
TPMS.

Changing a Tire with TPMS
If you have a flat tire, the Low Tire
Pressure and LCD position indicator
will come on. Have the flat tire
repaired by an authorized retailer of
Genesis Branded products as soon
as possible or replace the flat tire
with the spare tire.
Never use a puncture-repairing
agent not approved by authorized
retailer of Genesis Branded prod-
ucts to repair and/or inflate a low
pressure tire. Tire sealant not
approved by authorized retailer of
Genesis Branded products may
damage the tire pressure sensor.
The spare tire does not come with a
tire pressure monitoring sensor.
When the low pressure tire or the flat
tire is replaced with the spare tire,
the Low Tire Pressure LCD position
indicator will remain on. Also, the
TPMS Malfunction Indicator will illu-
minate after blinking for one minute if
the vehicle is driven at speed above
15.5 mph (25 km/h) for approximate-
ly 20 minutes.
Once the original tire equipped with
a tire pressure monitoring sensor is
reinflated to the recommended pres-
sure and reinstalled on the vehicle,
the Low Tire Pressure LCD position
indicator and TPMS Malfunction
Indicator will go off within a few min-
utes of driving.
If the indicators do not disappear
after a few minutes, please 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 serv-
iced by an authorized retailer of
Genesis Branded products.
You may not be able identify a tire
with low pressure by simply looking
at it. Always use a good quality tire
pressure 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 for
less than 1 mile (1.6 km) 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.
NOTICE
• The TPMS cannot alert you to
severe and sudden tire dam-
age caused by external fac-
tors such as nails or road
debris.
• 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.
