STARTING AND DRIVING
(b) Using engine braking
31R009c
To use the braking power of the engine, downshift the transmission
in the way described below:
1 Turn off the overdrive switch. (This is effective only when you
are driving in the "D" position.) The "O/D OFF" indicator light
in the instrument cluster will come on and the transmission will
downshift to the third gear and engine braking will be obtained.
When the cruise control is being used, even if you downshift
the transmission by turning off the overdrive switch, engine
braking will not be applied because the cruise control is not
cancelled. If you need to decrease the vehicle speed, see page
180.
