Fuel Gauge
The fuel gauge shows the approximate amount of fuel in the
fuel tanks. Besides empty and full, the gauge also indicates
1/4, 1/2 and 3/4 of total fuel capacity.
Your truck has one main fuel tank and up to four optional
tanks. The fuel gauge shows the total amount of fuel. It is a
good idea to keep fuel tanks at least half–full; otherwise,
water that condenses in an empty tank will contaminate the
fuel and could damage the engine.
WARNING! Do not carry additional fuel contain-
ers in your vehicle. Fuel containers, either full or
empty, may leak, explode, and cause or feed a
fire. Do not carry extra fuel containers, even
empty ones are dangerous.
WARNING! Do not remove a fuel tank cap near
an open flame. Hot fuel vapors are combustible
and can cause an explosion or fire resulting in
injury or death.
