Lincoln 2013 MKZ Owner's Manual page 160

If you have run out of fuel:
• You may need to cycle the ignition
from off to on several times after
refueling to allow the fuel system
to pump the fuel from the tank to
the engine. On restarting, cranking
time will take a few seconds longer
than normal. With keyless ignition,
just start the engine. Crank time
will be longer than usual.
• Normally, adding 1 gallon (3.8
liters) of fuel is enough to restart
the engine. If the vehicle is out of
fuel and on a steep grade, more
than 1 gallon (3.8 liters) may be
required.
• The service engine soon indicator
may come on.
Refilling With a Portable Fuel
Container
WARNINGS
Do not insert the nozzle of
portable fuel containers or
aftermarket funnels into the capless
fuel system. This could damage the
fuel system and its seal, and may
cause fuel to run onto the ground
instead of filling the tank, which could
result in serious personal injury.
Do not try to pry open or push
open the capless fuel system
with foreign objects. This could
damage the fuel system and its seal
and cause injury to you or others.

Note: Do not use aftermarket funnels;
they will not work with the capless fuel
system and can damage it. The
included funnel has been specially
designed to work safely with your
vehicle.
When filling the vehicle's fuel tank
from a portable fuel container, use the
funnel included with the vehicle.
