Accelerator downshift
— in D position —
For passing or hill climbing, depress the accel-
erator pedal to the floor. This shifts the transmis-
sion down into a lower gear, depending on the
vehicle speed.
Overdrive switch
Each time your vehicle is started, the transmis-
sion is automatically “reset” to overdrive ON.
ON: With the engine running and the
shift selector lever in the D (Drive)
position, the transmission upshifts
into Overdrive as vehicle speed
increases.
Overdrive does not engage until the engine
has reached operating temperature.
OFF: For driving up and down long
slopes where engine braking is nec-
essary push the Overdrive switch
once. The O/D OFF indicator light
in the instrument panel comes on at
this time.
When cruising at a low speed or climbing a
gentle slope, you may feel uncomfortable shift
shocks as the transmission shifts into and out of
Overdrive repeatedly. In this case, depress the
Overdrive switch to turn the Overdrive off. The
O/D OFF indicator light in the instrument panel
comes on at this time.
When driving conditions change, depress the
Overdrive switch to turn the Overdrive on.
Remember not to drive at high speeds for ex-
tended periods of time with the Overdrive off.
This reduces fuel economy.
