• Never attempt to place the vehicle
in motion, or run the engine with
batteries disconnected
• Keep the battery clean and dry
• Look for any signs of damage
• Battery terminals should not be
coated with improper grease. Use
a commercially available,
noncorrosive, non-conductive
terminal coating, or petroleum jelly.
• Never use a fast charger as a
booster to start the engine. This
can seriously damage sensitive
electronic components such as
relays, radio, etc., as well as the
battery charger. Fast charging a
battery is dangerous and should
only be attempted by a competent
mechanic with the proper
equipment.
Under Cab Battery Access
The battery compartment is located on the
left side of the vehicle, under the cab
access steps.
1. Remove the six bolts that are
located in the two cab access step
plate.
2. Remove battery cover for access.
In Cab Battery Access
Your vehicle may be equipped with
Absorbed Glass Mat (AGM) batteries
located in the cab under the passenger's
seat. The glass mat in AGM batteries are
designed to absorb the battery acid inside
the battery that can leak or spill out in
conventional batteries. This design feature
allows batteries to be positioned in any
orientation without risk of leaking.
To access the batteries:
1. Enter the cab.
2. Remove six fasteners securing the
passenger side seat base to the
battery box assembly.
3. Remove the seat and seat base as
one unit to gain access to the
batteries.
4. Installation is the reverse of
removal.
Cranking Battery Specification
Category Specification
Group 31
Stud Type Threaded
Cold Crank Amps 650
Category Specification
Voltage 12 V
Reserve Capacity 160 minutes
General Maintenance free
Removing Batteries
After accessing the batteries, follow these
steps to remove them from the vehicle.
CAUTION
Wait at least 10 minutes after the key
switch is turned OFF before discon-
necting battery power. The system
uses battery power to circulate DEF
and prevent overheating of the DEF
system. Failure to comply may result
in property damage.
1. Be sure all switches on the vehicle
are turned OFF
2. Wait 10 minutes after turning
ignition off before disconnecting the
batteries
3. Disconnect negative (-) ground
cable first
