278 MAINTENANCE AND LUBRICATION

FUELING

DANGER
DO NOT carry extra fuel containers in the cab. Fuel containers, full or empty,
may leak, explode or give added fuel to a fire. Failure to follow this precaution
may lead to serious personal injury or death.
DANGER
DO NOT smoke while fueling the vehicle. The glow from the cigar/cigarette can
ignite the diesel fuel, causing an explosion resulting in serious personal injury
or death.
DANGER
Do not remove the fuel tank cap near an open flame. Diesel fuel vapors are
combustible and can cause an explosion or fire, resulting in severe personal
injury or death.
CAUTION
Diesel-powered engines for heavy-duty trucks built on or after January 1, 2010 are
designed to operate only with Ultra Low Sulfur Diesel (ULSD) fuel. Improper
fuel use will reduce the efficiency and durability of engines, permanently damage
advanced emissions control systems, reduce fuel economy and possibly prevent the
vehicles from running at all. Manufacturer warranties will be voided by improper
fuel use. Additionally, burning Low Sulfur Diesel fuel (instead of ULSD fuel) in
2010 and later model year diesel-powered cars, trucks and buses is illegal and
punishable with civil penalties.
