"N" Neutral
Shift to Neutral when the vehicle is standing for pro-
longed periods with the engine running. The engine may
be started in this range. Set the parking brake if you must
leave the vehicle.
"D" Drive
Drive range provides underdrive 1st, 2nd and 3rd gears,
direct 4th gear and overdrive 5th and 6th gears. The shift
into overdrive 5th and 6th gear occurs only after the
transmission has completed the shift into 4th gear. No
other movement of the shift mechanism is required to
complete the 4–5 or 5–6 gear shifts.
The 4th and 5th gear upshifts occurs automatically unless
the Tow/Haul mode is enabled.
Upshifts into both overdrive gears, 5th and 6th, will be
delayed when the transmission fluid temperature is
below 40° F (4.5° C) or above 240° F (115.5° C).
STARTING AND OPERATING 287
NOTE: Use caution when operating a heavily loaded
vehicle in 2nd or 1st gear in high ambients as torque
converter slip can impose significant additional heat load
on the cooling system.
WARNING!
Never use Park position on an automatic transmis-
sion as a substitute for the parking brake. Always
apply parking brake fully when parked to guard
against vehicle movement and possible injury or
damage.
