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.162, 163)

●

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.

■

●

The Stop & Start system is opera-

tional when all of the following

conditions are met:

• The vehicle has been driven a cer-

tain amount of time.

• The brake pedal is being

depressed firmly. (Except when

the vehicle is stopped by the

dynamic radar cruise control with

full-speed range when in vehi-

cle-to-vehicle distance control

mode)



P.240)

●

In the following situations the

engine may not be stopped by the

Stop & Start system. This is not a

malfunction of the Stop & Start

system.

• When the air conditioning system

is being used.

• When the battery is undergoing a

periodic recharge.

• When the battery is not sufficiently

charged, such as if the vehicle

has been parked for a long time

and the battery charge has

decreased, the electric load is

large, the battery fluid tempera-

ture is excessively low or the bat-
tery has deteriorated.

• When the brake booster vacuum

is low.

• When the elapsed time since the

engine was restarted is short.

• When the vehicle is stopped fre-

quently, such as when in a traffic

jam.

• When the engine coolant tem-

perature or transmission fluid tem-

perature is extremely low or high.

• When the vehicle is stopped on a

steep incline.

and will not be able to be restarted

by the automatic engine start

function. In this case, restart the

engine using the normal engine

starting procedure. (

onds or more, and then start the

engine.

■

Air conditioning system opera-

tion while the engine is stopped

by the Stop & Start system

Vehicles with an automatic air con-

ditioning system: When the air con-

ditioning is in automatic mode and

the engine is stopped by the Stop &

Start system, the fan may operate at

a low speed in order to prevent the

temperature in the cabin from

increasing or decreasing or may be

stopped.

& Start system indicator will flash. To

stop the buzzer, close the driver’s

door.

■

The Stop & Start system protec-

tion function

●

When the volume of the audio

system is excessively high, sound

output from the audio system may

suddenly be cut off in order to

reduce 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.

●

The audio system may not be acti-

vated if the battery terminals are

disconnected and then recon-

nected. If this occurs, turn the

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.

●

If any of the following situations

occur, the Stop & Start system

may not operate correctly. Have

your vehicle inspected by your

Toyota dealer.

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. Always drive

safely, taking care to observe

your surroundings.

●

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 func-

tion cannot judge if it is safe to

change lanes, over reliance

could lead to an accident result-

ing in death or serious injury. As

the system may not function

correctly under certain condi-

tions, the driver’s own visual

confirmation of safety is neces-

sary.

detected side will illuminate. If the
turn signal lever is operated toward
the detected side, the outside rear

WARNING

■

To ensure the system can

operate properly

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 will be dis-
played. In this situation, clear off
the dirt or snow and drive the
vehicle with the operation condi-
tions of the BSM function
(



P.247) satisfied for approxi-

mately 10 minutes. If the warning
message does not disappear,
have the vehicle inspected by
your Toyota dealer.

●

Do not attach accessories,

stickers (including transparent

stickers), aluminum tape, etc. to

a sensor or its surrounding area

on the rear bumper.

■

Objects that can be detected while driving

The Blind Spot Monitor uses rear side radar sensors to detect the fol-
lowing vehicles traveling in adjacent lanes and advises the driver of
the presence of such vehicles via the indicators on the outside rear
view mirrors.

WARNING

●

Do not subject a sensor or its

surrounding area on the rear

bumper to a strong impact.

If a sensor is moved even

slightly off position, the system

may malfunction and vehicles

may not be detected correctly.

In the following situations, have

your vehicle inspected by your

Toyota dealer.

• A sensor or its surrounding area

is subject to a strong impact.

• If the surrounding area of a sen-

sor is scratched or dented, or

part of them has become dis-

connected.

●

Do not disassemble the sensor.

●

Do not modify the sensor or sur-

rounding area on the rear

bumper.

●

If a sensor or the rear bumper

needs to be removed/installed

or replaced, contact your Toyota

dealer.

●

Do not paint the rear bumper

any color other than an official

Toyota color.

Detection range while driving

The areas that vehicles can be detected in are outlined below.

The range of each detection area is:

that is wet with standing water

during bad weather, such as

heavy rain, snow, or fog

• When multiple vehicles are

approaching with only a small gap

between each vehicle

• When the distance between your

vehicle and a following vehicle is

short

• When there is a significant differ-

ence in speed between your vehi-

cle and the vehicle that enters the

detection area

• When the difference in speed

between your vehicle and another

vehicle is changing

• When a vehicle enters a detection

area traveling at about the same

speed as your vehicle

• As your vehicle starts from a stop,

a vehicle remains in the detection

RCTA (Rear Cross Traf-

fic Alert)

BSM rear side radar sensors
installed behind the rear
bumper. This function is
intended to assist the driver
in checking areas that are
not easily visible when
backing up.

WARNING

■

Cautions regarding the use of

the system

The driver is solely responsible for

safe driving. Always drive safely,

taking care to observe your sur-

roundings. The RCTA function is

only a supplementary function

which alerts the driver that a vehi-

cle is approaching from the right

or left at the rear of the vehicle. As

the RCTA function may not func-

tion correctly under certain condi-

tions, the driver’s own visual

confirmation of safety is neces-
