Fluid cap is also behind the fuel
door. Do not remove both caps at
the same time.

Turn the fuel cap counterclockwise
to remove. When refueling, hang the
fuel cap from the hook on the fuel
door. Fully insert and latch the fill
nozzle, begin fueling.

{

Warning

Overfilling the fuel tank by more
than three clicks of a standard fill
nozzle may cause:

.

Vehicle performance issues,
including engine stalling and
damage to the fuel system.

.

Fuel spills.

.

Under certain conditions,
fuel fires.

Diesel fuel can foam when filling the
tank. The automatic pump nozzle
may shut off, even if the tank is not
full. Wait for the foaming to stop,
and then fill the tank more slowly.
Be careful not to spill fuel. Wait
five seconds after pumping before

removing the fill nozzle. Clean fuel
from painted surfaces as soon as
possible. See

Reinstall the cap by turning it
clockwise until it clicks. Push the
fuel door closed.

{

Warning

If a fire starts while you are
refueling, do not remove the fill
nozzle. Shut off the flow of fuel by
shutting off the pump or by
notifying the station attendant.
Leave the area immediately.

Caution

If a new fuel cap is needed, be
sure to get the right type of cap
from your dealer. The wrong type
of fuel cap may not fit properly
and could damage the fuel
system.

Accidental Refueling with
Gasoline

Caution

If the vehicle is accidentally
refueled with gasoline, do not
continue driving the vehicle
except to get to a location where
it can be stopped safely. Driving
the vehicle will damage the
engine. Tow the vehicle for
service. Have the gasoline
removed from the tank and fuel
system.

Filling a Portable Fuel
Container

{

Warning

Filling a portable fuel container
while it is in the vehicle can cause
fuel vapors that can ignite either
by static electricity or other
