The vehicle has a locking fuel fill cover. Use
the fuel fill cover key to unlock the cover.
The key cannot be removed in the unlocked
position. When reinstalling the fuel fill cover,
be sure the arrow is pointing straight up.
The capless refueling system does not have
a fuel cap. 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.
Be careful not to spill fuel. Wait five seconds
after you have finished pumping before
removing the fill nozzle. Clean fuel from
painted surfaces as soon as possible. See
Exterior Care 0 348. 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.
Driving and Operating
Filling the Tank with a Portable Fuel
Container
If the vehicle runs out of fuel and must be
filled from a portable fuel container:
1. Locate the capless funnel adapter.
2. Insert and latch the funnel into the
capless fuel system.
Warning
Attempting to refuel from a portable fuel
container without using the funnel
adapter may cause fuel spillage and
damage the capless fuel system. This
could cause a fire. You or others could be
badly burned and the vehicle could be
damaged.
3. Remove and clean the funnel adapter
and return it to the storage location.
