If you have run out of fuel:
• If your vehicle is equipped with dual fuel tanks, adding four–five
gallons (15–19 liters) of fuel is enough to restart the engine. If your
vehicle is out of fuel and on a steep grade, more than four–five
gallons (15–19 liters) may be required.
• The fuel system must be primed before attempting to restart the
engine. See your engine operator’s manual for instructions on priming
the engine.
• Use caution not to overheat and damage the starter by cranking the
engine for an excessive period. You may need to crank the engine for
a longer time than normal. If the engine fails to start in 30 seconds,
turn the ignition to the off position and wait for two minutes before
cranking the engine again.
• Any remaining trapped air self-purges from the fuel system once the
engine starts running.
• The engine may run rough and produce white smoke while air is in
the fuel system. This is normal and should stop after a short period.
See General information in the Information Displays chapter for
information on Miles to Empty.
REFUELING
WARNING: Fuel vapor burns violently and a fuel fire can cause
severe injuries. To help avoid injuries to you and others:
• Read and follow all the instructions on the pump island.
• Turn off your engine when you are refueling.
• Do not smoke if you are near fuel or refueling your vehicle.
• Keep sparks, flames and smoking materials away from fuel.
• Stay outside your vehicle and do not leave the fuel pump unattended
when refueling your vehicle - this is against the law in some places.
• Keep children away from the fuel pump; never let children pump
fuel.
• Do not use personal electronic devices while refueling.
Use the following guidelines to avoid electrostatic charge build-up when
filling an ungrounded fuel container:
• Place approved fuel container on the ground.
