2. Connect one end of the other jumper cable to negative(-) post of booster battery. Connect the other end of the
jumper cable to a good ground on the engine block of
the vehicle with the discharged battery. Make sure a
good connection is made, free of dirt and grease.
WARNING!
•Do not connect the cable to the negative post of the
discharge battery. The resulting electrical spark
could cause the battery to explode.
• During cold weather when temperatures are below
freezing point, electrolyte in a discharged battery
may freeze. Do not attempt jump starting because
the battery could rupture or explode. The battery
temperature must be brought up above freezing
point before attempting to jump start. 3. Take care that the clamps from one cable do not
inadvertently touch clamps from the other cable. Do
not lean over the battery when making connection.
The negative connection must provide good electrical
conductivity and current carrying capacity.
4. After the engine is started or if the engine fails to start, cables must be disconnected in the following order:
• Disconnect the negative cable at the engine ground.
• Disconnect the negative cable at the negative post on
booster battery.
• Disconnect the cable from the positive post of both
batteries.

WARNING!(Continued)
grass or leaves coming into contact with your exhaust
system. Do not park or operate your vehicle in areas
where your exhaust system can contact anything that
can burn.
Diesel Exhaust Fluid
Diesel Exhaust Fluid (DEF) sometimes known simply by
the name of its active component, UREA—is a key
component of selective catalytic reduction (SCR) systems,
which help diesel vehicles meet stringent emission regu-
lations. DEF is a liquid reducing agent that reacts with
engine exhaust in the presence of a catalyst to convert
smog-forming nitrogen oxides (NOx) into harmless ni-
trogen and water vapor.
Refer to “Fluids, Lubricants, and Genuine Parts” in
“Maintaining Your Vehicle” for further information. You can receive assistance in locating DEF in the United
States by calling 866-RAM-INFO (866-726-4636). In
Canada call 1–800–465–2001 (English) or 1–800–387–9983
(French)
Maintenance-Free Batteries
The top of the maintenance-free batteries are perma-
nently sealed. You will never have to add water, nor is
periodic maintenance required.
NOTE:
Replacement batteries should both be of equal
capacity to prevent damage to the vehicle’s charging
system.
CAUTION!
It is essential when replacing the cables on the
battery that the positive cable is attached to the
positive post and the negative cable is attached to the
