Dodge 2008 Ram Pickup 3500 - Manual (Page 270)

ENGINE BLOCK HEATER (GAS ENGINES)— IF
EQUIPPED
The engine block heater warms engine coolant and
permits quicker starts in cold weather. Connect the cord
to a standard 110-115 volt AC electrical outlet with a
grounded, three-wire extension cord.
The engine block heater cord, on gas engines, is routed
under the hood on the driver side of the vehicle. It has a
removable cap that is located on the driver side of the
Integrated Power Module.
WARNING!
Remember to disconnect the cord before driving.
Damage to the 110-115 volt electrical cord could cause
electrocution.
DIESEL EXHAUST BRAKE (ENGINE BRAKING) –
IF EQUIPPED
The exhaust brake feature will only function when the
driver turns the exhaust brake switch to the on position.
Once the switch is in the on position and the vehicle is
moving faster than 5 MPH; the exhaust brake will
automatically operate when the driver removes pressure
from the accelerator pedal. Exhaust braking is most
effective when the engine RPM is higher. The automatic
transmission has been programmed to downshift more
aggressively when the exhaust brake is enabled to in-
crease brake performance.
