3105-1. Before driving
Prius Plug-in Hybrid_OM_OM47E75E_(EE)QDriving in the rain
ODrive carefully when it is raining, because visibility will be reduced, the win-
dows may become fogged-up, and the road will be slippery.
ODrive carefully when it starts to rain, because the road surface will be espe-
cially slippery.
ORefrain from high speeds when driving on an expressway in the rain,
because there may be a layer of water between the tires and the road sur-
face, preventing the steering and brakes from operating properly.
QRestraining the hybrid system output (Brake Override System)
OWhen the accelerator and brake pedals are depressed at the same time, the
hybrid system output may be restrained.
OA warning message is displayed on the multi-information display while the
system is operating. (P. 671)
Q“ECO Accelerator Guidance” (P. 229)
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.
OWhen 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.
OWhen 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.
OWhen stopping:
When stopping the vehicle, early releasing the accelerator pedal will cause
the “Eco-Stop” score to increase.
QDrive-Start Control (DSC)
When the TRC is turned off (P. 511), sudden start restraint control also
does not operate. If your vehicle have trouble escaping from the mud or fresh
snow due to sudden start restraint control operation, deactivate TRC (P.
511) so that the vehicle may become able to escape from the mud or fresh
snow.
