Your veh icle fuel tank has an onboard refue l­
ling vapor recovery system. This feature helps
to prevent fuel vapors from escaping from the
tank and polluting the environment while you refuel your vehicle. In order to fill the tank
properly whi le protecting the env ironment,
please follow this refueling procedure careful­
ly .
A WARNING
Under normal operating conditions, neve r
carry additiona l fuel containers in you r car.
Gas canisters and other containers used to
transport fuel can be dangerous. Such con­
tainers, full or empty, may leak and could
cause a fire in a collision. If you must
transport fue l to use for yo ur lawn mower,
snow blower, etc., be very careful and al­
ways observe local and state laws regard­
ing the use, transportation and storage of such
fuel containers . Make certain the con­
tainer meets industry standards (ANSI/
ASTM F852 -86).
(D Note
Never drive your vehicle until the fue l tank
is completely empty. The irregu lar supply
of fue l can cause misfiring. Gasoline could
enter the exhaust system and damage the
catalytic converter .

Refuelling procedure
"'Insert the fuel nozz le from the gasoline
pump into the fue l filler neck as far as it will
go.
"' Se lect a medium refuelling rate so that the
noz zle switches off automatically when the
tank is full.
Putting the fuel cap back on
"'After filling your tank, twist the fuel fi ller
cap clockwise as far as it will go.
"' Close the fuel filler flap .
To avoid fuel spi lling or evaporating from the
fuel tank always close fuel fi ller cap properly
and comp letely. An improperly closed fuel fill­
er cap may also cause the MIL lamp¢
page 29
to come on.
A WARNING
Improper refueling or handling of fuel can
cause fire, explosion and severe burns .
- Fuel is highly flammable and can cause
severe burns and other injuries .
- Failure to shut the eng ine off while refu­
eling and/or to insert the pump nozzle
fully into the fuel f iller neck could cause
fuel to spray out of filler neck or to over­
flow. Fuel spray and ove rflow ing fuel can
cause a fire.
- Never use a cellular telephone while re­
fueling. The elect romagnetic radiation
can cause sparks that can ignite fue l va­
pors and cause a fire.
- Never get back into you r vehicle while re­
fueling. If in exceptiona l circumstances
yo u must get back in your vehicle wh ile
refueling, make certain that you close
the door and touch metal to discharge
static electricity before touching the fill­
er nozzle again. Static electricity can
cause sparks that can ignite fuel vapors
released during refueling.
- Never smoke or have an open flame any­
where in or near you r vehicle when refu­
eling or filling a portable fuel container .
- For your safety, we strongly recommend
that you do not travel w ith a portable
Fuel supply and filling your fuel tank 217
fuel container in your vehicle. The con­
tainer, full or empty may leak and could
cause a fire, especially in a crash.
- If, under exceptional circumstances, you
must transport a portable fuel container,
please observe the following:
- Never fill a portable fuel container
while it is anywhere in or on the vehicle
(for example, in the luggage compart­
ment, or on the trunk) . Static electrici­
ty can build up while filling and can ig­
nite fuel vapors causing a fire.
- Always place a portab le fue l conta iner
on the ground before fi lling.
- Always keep the filler nozzle complete­
l y inside the portable container before
and during filling.
- If filling a portab le container made of
metal, the fi ller nozzle must always be
i n contact with the conta iner. This will
help prevent static electric ity from dis­
charging and cause a fire .
- Never spill fuel inside the vehicle or
luggage compartment. Fuel vapors are
highly flammable .
- Always observe local and state/provin­
cial laws regarding the use, storage
and transportation of fuel containers .
- Make certain the fuel container meets
industry standards (ANSI/ ASTM
F8S2 -86) .
(D Note
If any fuel has spilled onto the car, it
should be removed immediately to prevent
damage to the paint .
@) For the sake of the environment
As soon as the correctly operated nozzle
switches off automatically for the first
time, the tank is full. Do not try to add
more fuel because fuel may spill out . In
addition , the expansion space in the fuel
tank will be filled -causing the fuel to
overflow when it becomes warm and pol­
l ute the environment . •
