Information
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 deicer fluid (do not use
radiator antifreeze) 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.
WARNING
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 nozzle, you
should eliminate the potential build-
up of static electricity by touching
a metal part of the vehicle, a safe
distance away from the fuel filler
neck, nozzle, or other gas source,
with your bare hand.
• Do not use cellular phones while
refueling. Electric current and/or
electronic interference from cellular
phones can potentially ignite fuel
vapors and cause a fire. •
Do not get back into a vehicle
once you have begun refueling.
You can generate a buildup of
static electricity by touching,
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 dangerous
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.
• When using an approved portable
fuel container, be sure to place the
container on the ground prior to
refueling. Static electricity discharge
from the container can ignite fuel
vapors causing a fire.
Once refueling has begun, contact
between your bare hand and the
vehicle should be maintained until
the filling is complete.
• Use only approved portable plastic
fuel containers designed to carry and
store gasoline.
• When refueling, always move the
shift button to the P (Park) position
set the parking brake, and place
the ignition switch to the LOCK/
OFF position. Sparks produced by
electrical components related to the
engine can ignite fuel vapors causing
a fire.
• Do not use matches or a lighter and
do not smoke or leave a lit cigarette
in your vehicle while at a gas station,
especially during refueling.
• Do not over-fill or top-off your
vehicle tank, which can cause gasoline spillage.
