■Restraining the hybrid system output (Brake Override System)
●When the accelerator and brake pedals are depressed at the same time, the
hybrid system output may be restrained.
●A warning message is displayed on the multi-information display while the
system is operating. (P. 729)
■“ECO Accelerator Guidance” (P. 239)
It is easier to drive in an Eco-friendly manner by driving while referring to the
“ECO Accelerator Guidance” display. Also, by using the “ECO Accelerator
Guidance”, it is easier to increase the Eco score evaluation.
●When starting off:
While staying within the “ECO Accelerator Guidance” range, gradually
depress the accelerator pedal and accelerate to the desired speed. If exces-
sive acceleration is avoided, the “Eco-Start” score will increase.
●When driving:
After accelerating to the desired speed, release the accelerator pedal and
drive at a stable speed within the “ECO Accelerator Guidance” range. By
keeping the vehicle within the “ECO Accelerator Guidance” range, the “Eco-
Cruise” score will increase.
●When stopping:
When stopping the vehicle, early releasing the accelerator pedal will cause
the “Eco-Stop” score to increase.
■Restraining sudden start (Drive-Start Control)
●When the following unusual operation is performed, the hybrid system out-
put may be restrained.
• When the shift position is shifted from R to D/B, D/B to R, N to R, P to D/
B
*, P to R* with the accelerator pedal depressed, a warning message
appears on the multi-information display. If a warning message is shown
on the multi-information display, read the message and follow the instruc-
tions.
• When the accelerator pedal is depressed too much while the vehicle is in
reverse.
●While Drive-Start Control is being activated, your vehicle may have trou-
ble escaping from the mud or fresh snow. In such case, deactivate TRC
(P. 561) to cancel Drive Start Control so that the vehicle may become
able to escape from the mud or fresh snow.
*: Depending on the situation, the shift position may not be changed.
