The maximum allowable speeds are as follows.
Downshifting
■
AI-SHIFT
AI-SHIFT automatically selects the suitable gear according to driver perfor-
mance and driving conditions.
AI-SHIFT automatically operates when the shift lever is in the D position.
When driving downhill, there may be cases where the vehicle shifts down
automatically to obtain engine braking. As a result of the downshifting, the
engine speed may increase.

Engine braking will not occur when downshifting from D. (→P. 158)

If the shift lever cannot be shifted from P
→P. 328
CAUTION

Sudden changes in engine braking may cause the vehicle to spin or skid,
resulting in an accident.
