812-1. Plug-in hybrid system
2
Plug-in hybrid system
charge the hybrid battery (traction
battery) from external power
source or start the hybrid system
at least once every 2 or 3 months,
and turn the power switch off after
the gasoline engine has stopped
automatically. (If the gasoline
engine does not start up even
after approximately 10 seconds
have passed since the “READY”
indicator came on, the power
switch can be turned to off without
any further action.)
When the 12-volt battery is dis-
charged, refer to P.589, “If the 12-
volt battery is discharged” and
perform the correction procedure.
●When the vehicle is left with the
AC charging cable connected, the
electricity consumption amount of
the 12-volt battery increases due
to controls, such as the system
checking, operating. When the AC
charging cable is not needed,
remove it from the vehicle.
When driving with the gasoline
engine stopped, a sound, which
changes in accordance with the
driving speed, will be played in
order to warn people nearby of
the vehicle’s approach. The
sound will stop when the vehicle
speed exceeds approximately
22 mph (35 km/h).
■Acoustic Vehicle Alerting Sys-
tem
In the following cases, the Acoustic
Vehicle Alerting System may be dif-
ficult for surrounding people to hear.
●In very noisy areas
●In the wind or the rain
Also, as the Acoustic Vehicle Alert- ing System is installed on the front
of the vehicle, it may be more diffi-
cult to hear from the rear of the vehi-
cle compared to the front.
■When “Acoustic Vehicle Alert-
ing System Malfunction Visit
your Dealer” is displayed on the
multi-information display
The Acoustic Vehicle Alerting Sys-
tem may be malfunctioning. Have
the vehicle inspected by your
Toyota dealer immediately.
*: 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 sup-
port
 When the vehicle approaches
to predictive deceleration sup-
port points registered in the
navigation system, the refer-
ence operation range ( ) of
the ECO Accelerator Guid-
ance ( P.163) on the multi-
information display will be
turned off to encourage the
driver to reduce excessive
acceleration.

Driving
*: If equipped
When the front camera detects a sign or information
of a sign is available from the
navigation system, the sign
will be displayed on the dis-
play.
 Multiple signs can be dis-
played.
Depending on the specifications of
the vehicle, the number of dis-
played signs may be limited.
■Operating conditions of sign
display
Signs will be displayed when the fol-
lowing conditions are met:
●The system has detected a sign
In the following situations, a dis-
played sign may stop being dis-
played:
●When a new sign has not been
detected for a certain distance
●When the system determines that
the road being driven on has
changed, such as after a left or
right turn
■Situations in which the display
function may not operate prop-
erly
In the following situations, the RSA
system may not operate properly
and may not detect signs or may
display the incorrect sign. However,
this does not indicate a malfunction.
●When a sign is dirty, faded, tilted
or bent
●When the contrast of an electronic
sign is low
●When all or part of a sign is hidden
by a tree, utility pole, etc.
●When a sign is detected by the
front camera for a short amount of
time
●When the driving state (turning,
changing lanes, etc.) is judged
incorrectly
RSA (Road Sign
Assist)*
The RSA system detects
specific road signs using
the front camera and/or nav-
igation system (when speed
limit information is avail-
able) and warns the driver
via displays and buzzers.
WARNING
■For safe use
●Driving safely is solely the
responsibility of the driver. Pay
careful attention to the sur-
rounding conditions in order to
ensure safe driving.
●Do not rely solely upon the
RSA. The RSA assists the
driver by providing road sign
information, but it is not a
replacement for the driver’s own
vision and awareness. Driving
safely is solely the responsibility
of the driver. Pay careful atten-
tion to the surrounding condi-
tions in order to ensure safe
driving.
■Situations in which the RSA
should not be used
When it is necessary to disable
the system: P.284
■Situations in which the sys-
tem may not operate properly
●Situations in which the sensors
may not operate properly:
 P.289
Display Function

3305-5. Using the driving support systems
●When a sign is immediately after a
freeway junction or in an adjacent
lane just before merging
●When stickers are attached to the
rear of a preceding vehicle
●When a sign similar to a system
compatible sign is detected as a
system compatible sign
●When a speed limit sign for a
frontage road is within detection
range of the front camera
●When driving around a round-
about
●When a sign intended for trucks,
etc. is detected
●When the navigation system map
data is out of date
●When the navigation system can-
not be used
In this case, the speed limit signs
displayed on the multi-information
display and navigation system dis-
play may differ.
In the following situations, the
RSA system will output a warn-
ing to notify the driver.
 If the vehicle speed exceeds
the speed warning threshold
of the speed limit sign dis-
played on the display, the
sign display will be empha-
sized and a buzzer will sound.
 When the RSA system
detects a do not enter sign
and determines that the vehi-
cle has entered a no-entry
area, the do not enter sign
displayed on the display will
flash and a buzzer will sound.
■Operating conditions of the
notification functions
●Excess speed notification function
This function will operate when the
following condition is met:
• A speed limit road sign is recog- nized by the system.
●No entry notification function
This function will operate when all of
the following conditions are met:
• More than one no entry road signs are recognized by the system
simultaneously.
• The vehicle is passing between no
entry road signs recognized by the
system.
 The following types of road
signs can be displayed.
However, non-standard or recently
introduced traffic signs may not be
displayed.
