WARNING

■

Handling the radar sensor

●

Keep the sensor and its surrounding area on the bumper clean at all times.

●

Do not subject the sensor or surrounding area on the bumper to a strong impact. If

the sensor moves even slightly off position, the system may malfunction and vehicles

that enter the detection area may not be detected. If the sensor or surrounding area is

subject to a strong impact, always have the area inspected by your Lexus dealer.

●

Do not disassemble the sensor.

●

Do not attach accessories or stickers to the sensor or surrounding area on the

bumper.

●

Do not modify the sensor or surrounding area on the bumper.

●

Do not paint the rear bumper any color other than an official Lexus color.

One Blind Spot Monitor sensor is installed

inside the left and right side of the vehicle rear

bumper respectively. Observe the following to

ensure the Blind Spot Monitor can function

correctly.

289

4-5. Using the driving support systems

iving

The Blind Spot Monitor function uses radar sensors to detect vehicles that are
traveling in an adjacent lane in the area that is not reflected in the outside rear
view mirror (the blind spot), and advises the driver of the vehicle’s existence via
the outside rear view mirror indicator.

The areas that vehicles can be detected in are outlined below.
The range of the detection area
extends to:

Approximately 11.5 ft. (3.5 m) from
the side of the vehicle

The first 1.6 ft. (0.5 m) from the side of

the vehicle is not in the detection area

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

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 function is a supplementary function which alerts the driver

that a vehicle is present in the blind spot. Do not overly rely on the Blind Spot Monitor

function. The function cannot judge if it is safe to change lanes, therefore over reliance

could cause an accident resulting in death or serious injury.
According to conditions, the system may not function correctly. Therefore the driver’s

own visual confirmation of safety is necessary.

290

4-5. Using the driving support systems

■

The Blind Spot Monitor function is operational when

●

The BSM function is turned on.

●

Vehicle speed is greater than approximately 10 mph (16 km/h).

■

The Blind Spot Monitor function will detect a vehicle when

●

A vehicle in an adjacent lane overtakes your vehicle.

●

Another vehicle enters the detection area when it changes lanes.

■

Conditions under which the Blind Spot Monitor function will not detect a vehicle
The Blind Spot Monitor function is not designed to detect the following types of vehicles

and/or objects:

●

Small motorcycles, bicycles, pedestrians etc.

●

Vehicles traveling in the opposite direction

●

Guardrails, walls, signs, parked vehicles and similar stationary objects

●

Following vehicles that are in the same lane

●

Vehicles driving 2 lanes across from your vehicle

: Depending on conditions, detection of a vehicle and/or object may occur.

■

Conditions under which the Blind Spot Monitor function may not function correctly

●

The Blind Spot Monitor function may not detect vehicles correctly in the following con-

ditions:
• During bad weather such as heavy rain, fog, snow etc.

• When ice or mud etc. is attached to the rear bumper

• When driving on a road surface that is wet due to rain, standing water etc.

• When there is a significant difference in speed between your vehicle and the vehicle

that enters the detection area

• When a vehicle is in the detection area from a stop and remains in the detection

area as your vehicle accelerates

• When driving up or down consecutive steep inclines, such as hills, a dip in the road

etc.

• When multiple vehicles approach with only a small gap between each vehicle

• When vehicle lanes are wide, and the vehicle in the next lane is too far away from

your vehicle

• When the vehicle that enters the detection area is traveling at about the same speed

as your vehicle

• When there is a significant difference in height between your vehicle and the vehicle

that enters the detection area

• Directly after the BSM function is turned on

●

Instances of the Blind Spot Monitor function unnecessarily detecting a vehicle and/or

object may increase under the following conditions:
• When there is only a short distance between your vehicle and a guardrail, wall etc.

• When there is only a short distance between your vehicle and a following vehicle

• When vehicle lanes are narrow and a vehicle driving 2 lanes across from your vehi-

cle enters the detection area

• When items such as a bicycle carrier are installed on the rear of the vehicle

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 Rear Cross Traffic Alert function is only an assist and is not a replacement for care-

ful driving. The driver must be careful when backing up, even when using the Rear

Cross Traffic Alert function. The driver’s own visual confirmation of behind you and

your vehicle is necessary and be sure there are no pedestrians, other vehicles etc.

before backing up. Failure to do so could cause death or serious injury.
According to conditions, the system may not function correctly. Therefore the driver’s

own visual confirmation of safety is necessary.

292

TVD (Torque Vectoring Differential) (GS F)

With the engine switch in IGNITION
ON mode, pressing the TVD switch
changes the TVD control mode.

The current TVD control mode will be

displayed on the meters.

STANDARD mode

This is the default mode and provides

an optimum balance of driving agility

and stability.

SLALOM mode

This mode emphasizes enhanced

steering response.

TRACK mode

This mode emphasizes stability for

high speed sporty driving.

The multi-information display shows the distribution of driving force between the
right and left rear wheels. (

P. 119)

The TVD system distributes driving force (torque) between the right and left
rear wheels automatically. This system contributes to enhanced steering
response while cornering and increased traction when exiting a corner, pro-
viding an agile driving experience.

■

Automatic cancelation of the selected TVD control mode
SLALOM and TRACK mode are canceled when the engine switch is turned off. When

the engine switch is turned to IGNITION ON mode, the TVD system will be in STAN-

DARD mode.

■

Automatic disabling of the TVD system
If a malfunction is detected in the TVD system, a warning message will be displayed on

the multi-information display (

P. 444) and the TVD system will be disabled automati-

cally. If the system is disabled, driving force will not be distributed by the TVD but through

normal differential operation.

■

To protect the system
If the TVD fluid temperature becomes excessively high due to driving for a long time

under extremely high load conditions, a warning message will be displayed on the multi-

information display. (
