1 (First)

Use 1 (Low) to provide maximum

engine braking on steep

downgrades. Upshifts can be made

by shifting to 2 (Second) or to

(Overdrive). Selecting 1 (Low) at

higher speeds causes the transmission to shift to a lower gear, and will

shift to 1 (Low) after vehicle decelerates to the proper speed.

Forced Downshifts

To gain acceleration in (Overdrive) or Drive (O/D OFF) when

passing another vehicle, push the accelerator to the floor. The

transmission will downshift to the appropriate gear: third, second or first

gear.

Shift strategy (4R100 automatic transmission)

To account for customer driving habits and conditions, your 4R100

automatic transmission electronically controls the shift quality by using

an adaptive learning strategy. The adaptive learning strategy is

maintained by power from the battery. When the battery is disconnected

or a new battery is installed, the transmission must relearn its adaptive

strategy. Optimal shifting will resume within a few hundred kilometers

(miles) of operation.

If the shift quality does not improve within a few hundred

kilometers (miles) of operation, or if the downshifts and other

throttle conditions do not function normally, see your dealer or a

qualified service technician as soon as possible.
