Selecting shift ranges in the D position
To drive using temporary shift range selection, operate the “-”paddle shift
switch. The shift range can then be selected by operating the “-” and “+”
paddle shift switches. Changing the shift range allows restriction of the
highest gear, preventing unnecessary upshifting and enabling the level of
engine braking force to be selected. Higher shift range
Lower shift range
The selected shift range, from 1 to
8, will be displayed in the meter
cluster.
To return to normal D position
driving, the “+” paddle shift switch
must be held down for a period of
time.
■ Selecting a driving mode
The following modes can be sele cted to suit driving conditions
Snow mode
For accelerating and driving
on slippery road surfaces,
such as on snow.

changed in the following situations:
● When vehicle speed drops (downshift only).
● When the automatic transmission fluid or engine coolant temperature
is low.
