Benefits of the exhaust brake are:
•
vehicle driving control
•
reduced brake fade
•
longer brake life
•
faster cab warm-up.
The exhaust brake feature can also be used to reduce the
engine warm up time. To use the exhaust brake as a
warm-up device, the vehicle must be moving less than 5
MPH, the exhaust brake switch must be in the on
position, and the coolant temperature must below 180 F
and ambient temperature below 60 F.
TRANSMISSION SHIFTING
Automatic Transmission with Overdrive
(68RFE) — If Equipped
The gear shift selector display, located in the instrument
panel cluster, indicates the transmission gear range (the
selector is illuminated for night driving). The selector
lever is mounted on the right side of the steering column.
You must depress the brake pedal, to pull the selector
lever out of park (P) position (Brake Interlock System). To
drive, move the selector lever from Park or Neutral to the
desired drive position. Pull the selector lever toward you
when shifting into Reverse, or Park, or when shifting out
of Park.

DO NOT race the engine when shifting from Park or
Neutral position into another gear range.
