FORD 2015 F-550 v.1 - Manual (Page 217)

JUMP STARTING THE VEHICLE
WARNINGS
The gases around the battery can
explode if exposed to flames, sparks,
or lit cigarettes. An explosion could
result in personal injury or vehicle damage.
Batteries contain sulfuric acid which
can burn skin, eyes and clothing, if
contacted.
Use only an adequate-sized cable
with insulated clamps.
Preparing Your Vehicle
Note: Do not attempt to push-start your
automatic transmission vehicle. Automatic
transmissions do not have push-start
capability. Attempting to push-start a
vehicle with an automatic transmission may
cause transmission damage.
Note: Use only a 12-volt supply to start your
vehicle.
Note: Do not disconnect the battery of the
disabled vehicle as this could damage the
vehicle's electrical system.
Park the booster vehicle close to the hood
of the disabled vehicle, making sure the
two vehicles do not touch. Turn all
accessories off.
Connecting the Jumper Cables
WARNING
Do not attach the cables to fuel lines,
engine rocker covers, the intake
manifold or electrical components
as grounding points. Stay clear of moving
parts. To avoid reverse polarity
connections, make sure that you correctly
identify the positive (+) and negative (-)
terminals on both the disabled and booster
vehicles before connecting the cables.
Note: In the illustration, the bottom vehicle
represents the booster vehicle.
