WARNING
- Refueling
 If pressurized fuel sprays out, itcan cover your clothes or skin
and thus subject you to the risk
of fire and burns. Always remove
the fuel cap carefully and slowly.
If the cap is venting fuel or if you
hear a hissing sound, wait until
the condition stops before com-
pletely removing the cap.
 Do not "top off" after the nozzle automatically shuts off when
refueling.
 Tighten the cap until it clicks one time, otherwise the Malfunction
Indicator Light will illuminate.
 Always check that the fuel cap is installed securely to prevent fuel
spillage in the event of an acci-
dent.

(Continued)
Use only approved portable plas-
tic fuel containers designed to
carry and store gasoline.
 Do not use cellular phones while refueling. Electric current and/or
electronic interference from cel-
lular phones can potentially
ignite fuel vapors causing a fire.
 When refueling, always shut the engine off. Sparks produced by
electrical components related to
the engine can ignite fuel vapors
causing a fire. Once refueling is
complete, check to make sure the
filler cap and filler door are
securely closed, before starting
the engine.
 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. Automotive fuel is
highly flammable and can, when
ignited, result in fire.
(Continued)
(Continued)
 Do not get back into a vehicleonce you have begun refueling
since you can generate static
electricity by touching, rubbing
or sliding against any item or fab-
ric (polyester, satin, nylon, etc.)
capable of producing static elec-
tricity. Static electricity discharge
can ignite fuel vapors resulting in
rapid burning. If you must re-
enter the vehicle, you should
once again eliminate potentially
dangerous static electricity dis-
charge by touching a metal part
of the vehicle, away from the fuel
filler neck, nozzle or other gaso-
line source.
 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 with the vehicle
should be maintained until the
filling is complete.

WARNING -
Refueling dan-
gers
Automotive fuels are flammable
materials. When refueling, please
note the following guidelines care-
fully. Failure to follow these guide-
lines may result in severe personal
injury, severe burns or death by fire
or explosion.
 Read and follow all warningsposted at the gas station facility.
 Before refueling, note the loca- tion of the Emergency Gasoline
Shut-Off, if available, at the gas
station facility.
 Before touching the fuel nozzle, you should eliminate potentially
dangerous static electricity dis-
charge by touching another metal
part of the vehicle, a safe dis-
tance away from the fuel filler
neck, nozzle, or other gas source.

Integrated HomeLink
®Wireless Control
System
The HomeLink
®Wireless Control System
provides a convenient way to replace up
to three hand-held radio-frequency (RF)
transmitters with a single built-in device.
This innovative feature will learn the
radio frequency codes of most current
transmitters to operate devices such as
gate operators, garage door openers,
entry door locks, security systems, even
home lighting. Both standard and rolling
code-equipped transmitters can be pro-
grammed by following the outlined proce-
dures. Additional HomeLink
®information
can be found at: www.homelink.com or
by calling 1-800-355-3515. Retain the original transmitter of the RF
device you are programming for use in
other vehicles as well as for future
HomeLink
®programming. It is also sug-
gested that upon the sale of the vehicle,
the programmed HomeLink
®buttons be
erased for security purposes.
CAUTION
Before programming HomeLink
®to
a garage door opener or gate oper- ator, make sure that people andobjects are out of the way of thedevice to prevent potential harm or damage. Do not use HomeLink®
with any garage door opener thatlacks the safety stop and reversefeatures required by U.S. federal safety standards (this includes anygarage door opener model manu- factured before April 1, 1982). Agarage door that cannot detect anobject - signaling the door to stop and reverse - does not meet currentU.S. federal safety standards. Usinga garage door opener without these features increases the risk of seri-ous injury or death.
