RUNNING OUT OF FUEL
Avoid running out of fuel because this situation may have an adverse
effect on powertrain components.
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.
• Normally, adding 1 gallon (3.8L) of fuel is enough to restart the
engine. If the vehicle is out of fuel and on a steep grade, more than
1 gallon (3.8L) may be required.
• The service engine soon indicator may come on. For more information
on the service engine soon indicator, refer to the Instrument Cluster
chapter.
See Settings in the Instrument Cluster chapter for information on
calculating DTE (Distance to empty).
Refilling With a Portable Fuel Container
WARNING: Do not insert the nozzle of portable fuel containers
or aftermarket funnels into the Easy 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.
WARNING: Do not try to pry open or push open the Easy Fuel®
system with foreign objects. This could damage the fuel system
and its seal and cause injury to you or others.
With the Easy Fuel® "no cap" fuel system, use the following directions
when filling from a portable fuel container:
When filling the vehicle's fuel tank from a portable fuel container, use the
funnel included with the vehicle.
