With the gearshift lever in N (Neutral), the vehicle can be started and is
free to roll. Hold the brake pedal down while in this position.

pressing the transmission control
switch on the side of the gearshift
lever.

forward gears (1-4) except
overdrive.

shifting in and out of overdrive
occurs, hilly terrain, heavy loads,
trailer towing and when engine
braking is required.
• O/D OFF lamp is illuminated.

control switch. The O/D OFF
lamp will not be illuminated.
