STARTING AND DRIVING
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 re.
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 ame. Diesel fuel vapors are
combustible and can cause an explosion
or re, 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 efciency 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 2007 and later model year diesel-
powered cars, trucks and buses is illegal
and punishable with civil penalties.
Air is always present inside the fuel
tanks, entering mainly through the tank
ventilation. With the air being heated
and cooled, condensation is formed and
water is mixed in the fuel. To avoid
condensation when the vehicle is parked
for longer periods, ll the tanks up to
95% of capacity. Do not ll more than
that, as the fuel needs to have room for
expansion during the heat of the day.
