death or serious injury.

●

In heavy traffic

●

On roads with sharp bends

●

On winding roads

●

On slippery roads, such as those cov-

ered with rain, ice or snow

●

Stop & Start 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, intersection, etc., in
order to improve fuel economy and
reduce noise pollution caused by
the engine idling.

Automatic enabling of the Stop & Start

system

If the Stop & Start system is disabled 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 temporarily
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.

BSM (Blind Spot Monitor)

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 confirm-
ing safety when changing lanes.

WARNING

■

Cautions regarding the use of the sys-

tem

The driver is solely responsible for safe

driving. Always drive safely, taking care

to observe your surroundings.
The Blind Spot Monitor is a supplemen-

tary function which alerts the driver that a

vehicle is in a blind spot of the outside

rear view mirrors or is approaching rap-

idly 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 serious

injury.
As the system may not function correctly

under certain conditions, the driver’s own

visual confirmation of safety is necessary.

●

Do not attach stickers to the sensor or

surrounding area on the rear bumper.

●

Do not subject a sensor or its sur-

rounding 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 cor-

rectly.In the following situations, have

your vehicle inspected by any author-

ized Lexus retailer or Lexus authorized

repairer, or any reliable repairer.

• A sensor or its surrounding area is

Vehicles that can be detected by the Blind Spot Monitor

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

Vehicles that are traveling in areas that are not visible using the outside rear
view mirrors (the blind spots)
Vehicles that are approaching rapidly from behind in areas that are not visible
using the outside rear view mirrors (the blind spots)

■

The Blind Spot Monitor detection areas

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

The range of each detection area is:

Approximately 0.5 m (1.6 ft.) to 3.5 m (11.5 ft.) from either side of the vehicle

Approximately 1 m (3.3 ft.) forward of the rear bumper
Approximately 3 m (9.8 ft.) from the rear bumper

Approximately 3 m (9.8 ft.) to 60 m (197 ft.) from the rear bumper

: The area between the side of the vehicle and 0.5 m (1.6 ft.) from the side of the vehicle

cannot be detected.

WARNING

■

When using the Lexus parking

assist-sensor

Observe the following precautions.

Failing to do so may result in the vehicle

being unable to be driven safely and pos-

sibly cause an accident.

●

Do not use the sensor at speeds in

excess of 10 km/h (6 mph).

●

The sensors’ detection areas and reac-

tion times are limited. When moving

forward or reversing, check the areas

surrounding the vehicle (especially the

sides of the vehicle) for safety, and

drive slowly, using the brake to control

the vehicle’s speed.

●

Do not install accessories within the

sensors’ detection areas.

●

The area directly under the bumpers is

not detected.

Thin posts or objects lower than the

sensor may not be detected when

approached, even if they have been

detected once.

■

When to disable the function

In the following situations, disable the

function as it may operate even though

there is no possibility of a collision.

●

The vehicle is equipped with a fender

pole, wireless antenna or fog lights.

●

The front or rear bumper or a sensor

receives a strong impact.

If “Parking Assist Unavailable” is dis-

played on the multi-information display

●

Water may be continuously flowing over

the sensor surface, such as in a heavy

rain. When the system determines that it

is normal, the system will return to nor-

mal.

●

Initialization may not have been per-

formed after a battery terminal was dis-

connected and reconnected. Initialize the

system. (



P.366) If this message contin-

ues to be displayed even after initializa-

tion, have the vehicle inspected by any

authorized Lexus retailer or Lexus

authorized repairer, or any reliable

repairer.

■

If “Parking Assist Unavailable Clean

Parking Assist Sensor” is displayed on

the multi-information display

A sensor may be covered with ice, snow,

dirt, etc. Remove the ice, snow, dirt, etc.,

from the sensor to return the system to nor-

mal.
Also, due to ice forming on a sensor at low

temperatures, a warning message may be

displayed or the sensor may not be able to

detect an object. Once the ice melts, the

system will return to normal.

WARNING

●

A non-genuine Lexus suspension

(lowered suspension, etc.) is installed.

●

Towing eyelets are installed.

●

A backlit licence plate is installed.

■

When using Lexus parking assist-sen-

sor

In the following situations, the system

may not function correctly due to a sen-

sor malfunction, etc. Have the vehicle

checked by any authorized Lexus retailer

or Lexus authorized repairer, or any reli-

able repairer.

●

The Lexus parking assist-sensor oper-

ation display flashes or shows continu-

ously, and a beep sounds when no

objects are detected.

●

If the area around a sensor collides

with something, or is subjected to

strong impact.

●

If the bumper or grille collides with

something.

●

If the display flashes or is displayed

continuously and a buzzer does not

sound, except when the mute function

has been turned on.

●

If a display error occurs, first check the

sensor.

If the error occurs even when there is

no ice, snow or mud on the sensor, it is

likely that the sensor is malfunctioning.

■

Notes when washing the vehicle

Do not apply intensive bursts of water or

steam to the sensor area.
Doing so may result in the sensor mal-

functioning.

●

When using a high pressure washer to

wash the vehicle, do not spray the sen-

sors directly, as doing so may cause a

sensor to malfunction.

●

When using steam to clean the vehicle,

do not direct steam too close to the

sensors as doing so may cause a sen-

sor to malfunction.
