■Restraining the hybrid system o utput (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. 677)
■ “ECO Accelerator Guidance” (P. 226)
It is easier to drive in an Eco-friendly manner by driving whil e 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 spe ed. If exces-
sive acceleration is avoided, the “Eco-Start” score will increa se.
● When driving:
After accelerating to the desired speed, release the accelerato r 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 peda l will cause
the “Eco-Stop” score to increase.
■ Restraining sudden start (Drive-Start Control)
● When the following unusual operation is performed, the hybrid s ystem 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 t he instruc-
tions.
• When the accelerator pedal is depressed too much while the veh icle is in
reverse.

5-1. Before driving
WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury.
■When shifting the shift position
● Do not let the vehicle roll backward while a forward driving position is
selected, or roll forward while the shift position is in R.
Doing so may result in an accident or damage to the vehicle.
● Do not shift the shift position to P while the vehicle is movin g.
Doing so can damage the transmission and may result in a loss o f vehicle
control.
● Do not shift the shift position to R while the vehicle is moving forward.
Doing so can damage the transmission and may result in a loss o f vehicle
control.
● Do not shift the shift position to a driving position while the vehicle is mov-
ing backward.
Doing so can damage the transmission and may result in a loss of vehicle
control.
● Changing the shift position to N while the vehicle is moving will disengage
the hybrid system. Engine braking is not available with the hyb rid system
disengaged.
● Be careful not to change the shift position with the accelerato r pedal
depressed.
Changing the shift position to any position other than P or N may lead to
unexpected rapid acceleration of the vehicle that may cause an accident
and result in death or serious injury.
After changing the shift position, make sure to confirm the current shift
position displayed on the shift position indicator inside the meter.
