Pressing the cancel switch cancels
the speed control.

The speed control is also canceled when
the brake pedal is depressed.
(When the vehicle has been stopped by
system control, depressing the brake pedal
does not cancel the setting.)

Pressing the “+RES” switch
resumes the cruise control and
returns vehicle speed to the set
speed.

When your vehicle is too close to a
vehicle ahead, and sufficient automatic
deceleration via the cruise control is
not possible, the display will flash and
the buzzer will sound to alert the
driver. An example of this would be if
another driver cuts in front of you while
you are following a vehicle. Depress
the brake pedal to ensure an appropri-
ate vehicle-to-vehicle distance.

Turn the Blind Spot Monitor on/off.

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

function

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 nec-

essary.

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 vehi-

cle, do not direct steam too close to

the sensors as doing so may cause a

sensor to malfunction.

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.216)

If this message continues to be displayed

even after initialization, have the vehicle

inspected by your Lexus dealer.

■

If a battery terminal has been discon-

nected and reconnected

The system needs to be initialized. To initial-

ize the system, drive the vehicle straight

ahead for 5 seconds or more at a speed of

approximately 22 mph (35 km/h) or more.

Sensor detection information

●

The sensor’s detection areas are limited

to the areas around the vehicle’s front

and rear bumpers.

●

The following situations may occur

during use.

• Depending on the shape of the object

and other factors, the detection distance

may shorten, or detection may be impos-

sible.

• There will be a short delay between

object detection and display. Even at low

speeds, there is a possibility that the

object will come within the sensor’s

detection areas before the display is

shown and the warning beep sounds.

• It might be difficult to hear the buzzer due

to the volume of the audio system or air

flow noise of the air conditioning system.

• It may be difficult to hear the buzzer if

buzzers for other systems are sounding.

■

Objects which the system may not prop-

erly detect

The shape of the object may prevent the

sensor from detecting it. Pay particular

attention to the following objects:

●

Wires, fences, ropes, etc.

●

Cotton, snow and other materials that

absorb sound waves

●

Sharply-angled objects

●

Low objects

●

Tall objects with upper sections project-

ing outwards in the direction of your vehi-

cle

People may not be detected if they are

wearing certain types of clothing.

■

Situations in which the system may not

operate properly

Certain vehicle conditions and the sur-

rounding environment may affect the ability

of a sensor to correctly detect objects. Par-

ticular instances where this may occur are

listed below.

●

There is dirt, snow or ice on a sensor.

(Cleaning the sensors will resolve this

problem.)

●

A sensor is frozen. (Thawing the area will

resolve this problem.)

In especially cold weather, if a sensor is

frozen the sensor display may be dis-

played abnormally, or objects, such as a

wall, may not be detected.

●

When a sensor or the area around a sen-

sor is extremely hot or cold.

●

On an extremely bumpy road, on an

incline, on gravel, or on grass.

●

When vehicle horns, vehicle detectors,

motorcycle engines, air brakes of large

vehicles, the clearance sonar of other

vehicles or other devices which produce

ultrasonic waves are near the vehicle.

●

A sensor is coated with a sheet of spray

or heavy rain.

●

If objects draw too close to the sensor.

●

When a pedestrian is wearing clothing

that does not reflect ultrasonic waves (ex.

skirts with gathers or frills).

●

When objects that are not perpendicular
