What to do in an emergency
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.

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.
