°S± mode

●

When the shift range is “6” or lower, holding the shift lever toward “+” sets the

shift range to “8.”

●

When the shift lever is moved toward “-”, the shift range is downshifted to a

range that enables engine braking force that is suitable to driving conditions.

●

To prevent the engine from over-revving, upshifting may automatically occur.

Downshifting restrictions warning buzzer (in the °S± mode)

To help ensure safety and driving performance, downshifting operation may some-

when the shift lever is operated. (A buzzer will sound twice.)

■

When driving with the cruise control system

Engine brake will not operate in the “S” mode, even when downshifting to “7”, “6”,

“5” or “4”. (

The engine speed may remain high after releasing the accelerator pedal. This does

not indicate a malfunction.
