CAUTION!
See your authorized dealer, as damage to the exhaust
system could occur soon with continued operation.
Diesel Exhaust Fluid – Chassis Cab Only
Diesel Exhaust Fluid (DEF) sometimes known simply by
the name of its active component, UREA—is a key
component ofselective catalyticreduction (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 by calling
866-RAM-INFO (866-726-4636).
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
negative post. Battery posts are marked (+) positive
and negative (-) and are identified on the battery
case. Also, if a “fast charger” is used while the battery
is in vehicle, disconnect both vehicle battery cables
before connecting the charger to the battery. Do not
use a “fast charger” to provide starting voltage.
