WARNING! (Continued)
• It is dangerous to move the shift lever out of PARK
or NEUTRAL if the engine speed is higher than
idle speed. If your foot is not firmly on the brake
pedal, the vehicle could accelerate quickly forward
or in reverse. You could lose control of the vehicle
and hit someone or something. Only shift into
gear when the engine is idling normally and when
your foot is firmly on the brake pedal.
REVERSE
This range should be used only after the vehicle has come
to a complete stop.
NEUTRAL
Use this range when the vehicle is standing for prolonged
periods with the engine running. The engine may be
started in this range. Set the parking brake if you must
leave the vehicle.
DRIVE
This range provides underdrive first, second and third
gears, direct fourth gear and overdrive fifth and sixth
gears. The shift into overdrive fifth and sixth gear occurs
only after the transmission has completed the shift into
fourth gear. No other movement of the shift mechanism
is required to complete the 4–5 or 5–6 gear shifts.
Upshifts into both overdrive gears, fifth and sixth, will be
delayed when the transmission fluid temperature is
below 40°F (4.5°C) or above 240°F (115.5°C).
NOTE: Use caution when operating a heavily loaded
vehicle in second or first gear in high ambient tempera-
tures as torque converter slip can impose significant
additional heat load on the cooling system.
Overdrive Operation
The overdrive automatic transmission contains an elec-
tronically controlled fifth and sixth (Overdrive). The
