1-4. Hybrid system
■ If “Proximity Notification Sys-
tem Malfunction Visit Your
Dealer” is displayed on the
multi-information display
The system may be malfunctioning.
Have the vehicle inspected by your
Toyota dealer.

: This function can only be used in
the mainland U.S.A. It cannot be
used in other states and territo-
ries, including Alaska and Hawaii.
This system operates based on
the driving situation and traffic
information to enhance fuel
economy.
For details about Predictive effi-
cient drive, refer to “MULTIME-
DIA OWNER’S MANUAL”.
■ Predictive deceleration support
● When the vehicle approaches to
predictive deceleration support
points registered in the navigation
system, the zone of Eco accelera-
tion ( ) of the ECO Accelerator
Guidance (P.99) on the
multi-information display will be
turned off to encourage the driver
to reduce excessive acceleration.
Example: 7-inch display
● The engine braking force will be
increased according to the driving
conditions to more efficiently
charge the hybrid battery (traction
battery) after the accelerator pedal
is released.
■ Predictive SOC
*
control
The following types of control are
performed based on data such as
road and traffic information during
route guidance by the navigation
system to help ensure that the vehi-
cle efficiently uses electricity.
● When there is a long downhill
slope along the route, the system
reduces the hybrid battery (trac-
tion battery) level before reaching
the slope to help ensure charging
capacity for regenerative braking
while traveling downhill.
● When traffic congestion is pre-
dicted along the route, the system
helps ensure a certain battery
level before reaching congested
roads to reduce the frequency of
starting the engine to charge the
hybrid battery (traction battery)
due to low battery levels.
