■Conditions in which the func-
tion may not operate or detect
correctly
In the following situations, RSA
does not operate normally and may
not recognize signs, display the
incorrect sign, etc. However, this
does not indicate a malfunction.
●The front camera is misaligned
due to a strong impact being
applied to the sensor, etc.
●Dirt, snow, stickers, etc. are on the
windshield near the front camera.
●In inclement weather such as
heavy rain, fog, snow or sand
storms.
●Light from an oncoming vehicle,
the sun, etc. enters the front cam-
era.
●The sign is dirty, faded, tilted or
bent.
●The contrast of electronic sign is
low.
●All or part of the sign is hidden by
the leaves of a tree, a pole, etc.
●The sign is only visible to the front
camera for a short amount of time.
●The driving scene (turning, lane
change, etc.) is judged incorrectly.
●If a sign not appropriate for the

may be detected and displayed (if
positioned in sight of the front
camera) while traveling on a
roundabout.
●The front of the vehicle is raised or
lowered due to the carried load.
●The surrounding brightness is not
sufficient or changes suddenly.
●When a sign intended for trucks,
etc. is recognized.
●The navigation system map data
is outdated.
●The navigation system is not oper-
ating.
●The speed information displayed
on the meter and on the naviga-
tion system may be different due
to the navigation system using
map data.
■Speed limit sign display
If the engine switch was last turned
off while a speed limit sign was dis-
played on the multi-information dis-
play, the same sign displays again
when the engine switch is turned to
ON.

HIGHLANDER_U
*: If equipped
■Stopping the engine
While driving with the D shift
position selected, depress the
brake pedal and stop the vehi-
cle. The engine will stop auto-
matically.
When the engine stops, the Stop &
Start indicator will illuminate.
■Restarting the engine
Release the brake pedal. The
engine will start automatically.
When the engine starts, the Stop &
Start indicator will turn off.
■When the brake hold sys-
tem is operating
 When the engine is stopped
by the Stop & Start system, if
the brake pedal is released
the engine will remain
stopped.
 If the accelerator pedal is
depressed while the engine is
stopped by the Stop & Start
system, the engine will
restart.
 While the engine is stopped
by the Stop & Start system, if
the engine is restarted, the
brake hold system will con-
tinue to apply the brakes,
unless the operation condi-
tions of the brake hold system
are no longer met. ( P.214)
■When the dynamic radar
cruise control with
full-speed range is operat-
ing
 When the vehicle is stopped
by the dynamic radar cruise
control with full-speed range,
the engine will stop automati-
cally even though the brake
pedal is not depressed.
 When the preceding vehicle
starts off, the engine will
restart automatically.
 If the engine is restarted by
the Stop & Start system while
the vehicle is stopped by the
dynamic radar cruise control
with full-speed range, the
Stop & Star t system*
The Stop & Start system
stops and starts the engine
according to brake pedal or
shift lever operation when
the vehicle is stopped, such
as at a stoplight, intersec-
tion, etc., in order to
improve fuel economy and
reduce noise pollution
caused by the engine idling.

vehicle will remain stopped.
Press the Stop & Start cancel
switch to disable the Stop &
Start system.
The Stop & Start cancel indicator
will illuminate.
Pressing the switch again will
enable the Stop & Start system and
the Stop & Start ca ncel indicator will
turn off.
■Automatic enabling of the Stop
& Start system
If the Stop & Start system is dis-
abled using the Stop & Start cancel
switch, it will be automatically
re-enabled once the engine switch
is turned off and then the engine is
started.
When the engine is stopped by
the Stop & Start system when
the vehicle is on an incline,
when the brake pedal is
released, brake force is tempo-
rarily maintained to prevent the
vehicle from rolling backwards
before the engine is restarted and drive force is generated.
When drive force is generated,
the maintained brake force is
automatically canceled.

This function operates on flat
surfaces as well as steep
inclines.
 Sound may be generated
from the brake system, but
this does not indicate a mal-
function.
 Brake pedal response may
change and vibration may
occur, but this does not indi-
cate a malfunction.
■Points for use
●If the engine switch is pressed
when the engine is stopped by the
Stop & Start system, the engine
will not be able to be restarted by
the automatic engine start func-
tion. In this case, restart the
engine using the normal engine
starting procedure. ( P.202)
●When the engine is being
restarted by the Stop & Start sys-
tem, the power outlets may be
temporarily unusable, but this
does not indicate a malfunction.
●Installation and removal of electri-
cal components and wireless
devices may affect the Stop &
Start system. Contact your Toyota
dealer for details.
●When stopping the vehicle for a
longer period of time, turn the
engine switch off to stop the
engine completely.

HIGHLANDER_Ureduce battery consumption. To
prevent the audio system from
being cut off, keep the volume of
audio system at a moderate level.
If the audio system has been cut
off, turn the engine switch off, wait
for 3 seconds or more and then
turn it to ACC or ON to re-enable
the audio system.

WARNING
■When the Stop & Start system
is operating
Make sure to disable the Stop &
Start system while the vehicle is in
a poorly ventilated area. If not dis-
abled, the engine may be auto-
matically restarted unexpectedly,
causing exhaust gases to collect
and enter the vehicle, possibly
resulting in death or a serious
health hazard.
●Do not leave the vehicle while
the engine is stopped by the
Stop & Start system (while the
Stop & Start indicator is on). An
accident may occur due to the
automatic engine start function.
●Depress the brake pedal and
apply the parking brake when
necessary while the engine is
stopped by the Stop & Start sys-
tem (while the Stop & Start indi-
cator is on).
NOTICE
■To ensure the system oper-
ates correctly
If any of the following situations
occur, the Stop & Start system
may not operate correctly. Have
your vehicle inspected by your
Toyota dealer.

When a vehicle is detected in a
blind spot of the outside rear view
mirrors or approaching rapidly from
behind into a blind spot, the outside
rear view mirror indicator on the
detected side will illuminate. If the
turn signal lever is operated toward
the detected side, the outside rear
view mirror indicator flashes.
■Outside rear view mirror indica-
tor visibility
In strong sunlight, the outside rear
view mirror indicator may be difficult
to see.
■When “Blind Spot Monitor
Unavailable” is shown on the
multi-information display
Ice, snow, mud, etc., may be
attached to the rear bumper around
the sensors. ( P.280) The system
should return to normal operation
after removing the ice, snow, mud,
etc. from the rear bumper. Addition-
ally, the sensors may not operate
normally when driving in extremely
BSM (Blind Spot Moni-
tor)*
The Blind Spot Monitor is a
system that uses rear side
radar sensors installed on
the inner side of the rear
bumper on the left and right
side to assist the driver in
confirming safety when
changing lanes.
WARNING
■Cautions regarding the use of
the system
The driver is solely responsible for
safe driving. A lways drive safely,
taking care to observe your sur-
roundings.
The Blind Spot Monitor is a sup-
plementary function which alerts
the driver that a vehicle is in a
blind spot of the outside rear view
mirrors or is approaching rapidly
from behind into a blind spot. Do
not overly rely on the Blind Spot
Monitor. As the function cannot
judge if it is safe to change lanes,
over reliance could lead to an
accident resulting in death or seri-
ous injury.
As the system may not function
correctly under certain condi-
tions, the driver’s own visual con-
firmation of safety is necessary.

WARNING
■Handling the rear side radar
sensor
Blind Spot Monitor sensors are
installed behind the left and right
sides of the rear bumper respec-
tively. Observe the following to
ensure the Blind Spot Monitor can
operate correctly.
●Keep the sensors and the sur-
rounding areas on the rear
bumper clean at all times.
If a sensor or its surrounding area
on the rear bumper is dirty or cov-
ered with snow, the Blind Spot
Monitor may not operate and a
warning message (
P.278) will
be displayed. In this situation,
clear off the dirt or snow and drive
the vehicle with the operation con-
ditions of the BSM function
(
P.282) satisfied for approxi-
mately 10 minutes. If the warning
message does not disappear,
have the vehicle inspected by
your Toyota dealer.
●Do not attach stickers to the
sensor or surrounding area on
the rear bumper.
