NOTICE
If the fuel filler door does not open
because ice has formed around it,
tap lightly or push on the door to
break the ice and release the door.
Do not pry on the door. If necessary,
spray around the door with an
approved de-icer fluid (do not use
radiator anti-freeze) or move the
vehicle to a warm place and allow
the ice to melt.
Closing the fuel filler door
1. To install the fuel tank cap, turn it
clockwise until it “clicks” one time.
2. Close the fuel filler door until it is
latched securely.(Continued)Do not use cellular phones
while refueling. Electric cur-
rent and/or electronic interfer-
ence from cellular phones can
potentially ignite fuel vapors
and cause a fire.
Do not get back into a vehicle
once you have begun refuel-
ing. You can generate a build-
up of static electricity by touch-
ing, rubbing or sliding against
any item or fabric capable of
producing static electricity.
Static electricity discharge can
ignite fuel vapors causing a
fire. If you must re-enter the
vehicle, you should once again
eliminate potentially danger-
ous static electricity discharge
by touching a metal part of the
vehicle, away from the fuel filler
neck, nozzle or other gasoline
source, with your bare hand.
(Continued)Gasoline is highly flammable
and explosive. Failure to follow
these guidelines may result in
SERIOUS INJURY or DEATH:
Read and follow all warnings
posted at the gas station.
Before refueling, note the
location of the Emergency
Gasoline Shut-Off, if available,
at the gas station.
Before touching the fuel noz-
zle, you should eliminate the
potential build-up of static
electricity by touching a metal
part of the vehicle, a safe dis-
tance away from the fuel filler
neck, nozzle, or other gas
source, with your bare hand.

Fuel Gauge
This gauge indicates the approxi-
mate amount of fuel remaining in the
fuel tank.
✽ ✽
NOTICE
• The fuel tank capacity is given in
chapter 8.
• The fuel gauge is supplemented by
a low fuel warning light, which
will illuminate when the fuel tank
is nearly empty.
• On inclines or curves, the fuel
gauge pointer may fluctuate or the
low fuel warning light may come
on earlier than usual due to the
movement of fuel in the tank.
If the gauge pointer moves
beyond the normal range area
toward the "H" position, it indi-
cates overheating that may
damage the engine.
Do not continue driving with an
overheated engine. If your vehi-
cle overheats, refer to "If the
Engine Overheats" in chapter 6.
CAUTION
Never remove the radiator cap
when the engine is hot. The
engine coolant is under pres-
sure and could severely burn.
Wait until the engine is cool
before adding coolant to the
reservoir.
WARNING
ODH047057

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 indi-
cates a leak in the cooling sys-
tem and should be checked as
soon as possible by an author-
ized retailer of Genesis Branded
products.
CAUTION
NEVER remove the
radiator cap, drain
plug and heater hose
connector cap while
the engine and radia-
tor are hot. Hot coolant and
steam may blow out under pres-
sure, causing serious injury.
Turn the engine off and wait
until the engine cools down.
Use extreme care when remov-
ing the radiator 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 counterclock-
wise to remove it.
