About engine braking
■
When shift position B is selected, releasing the accelerator pedal will apply
engine braking.
When the vehicle is driven at high speeds, compared to ordinary gaso-
●
line-fueled vehicles, the engine braking deceleration is felt less than that
of other vehicles.
The vehicle can be accelerated even when shift position B is selected.
●
If the vehicle is driven continuously in the B position, fuel efficiency will
become low. Usually, shift the shift position to D.
When driving with cruise control or radar cruise control activated
■
Even if switching the driving mode to power mode with the intent of enabling
engine braking, engine braking will not activate because cruise control or
radar cruise control will not be canceled.
When canceling Eco drive mode/power mode
■
Press the switch again. Also, power mode will be canceled automatically
●
when the "POWER" switch is turned off. However, Eco drive mode will
not be canceled automatically until the switch is pressed, even if the
"POWER" switch is turned off.
When in Eco drive mode, if the power mode switch is pressed or the
●
operation is reversed, the mode will switch to that of the last switch to be
pressed.
