CAUTION
■Handling the radar sensor
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.
●Do not subject the sensor or surrounding ar ea on the bumper to a strong impact. If
the sensor moves even slightly off positi on, 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 sensor or surrounding area on the bumper.
●Keep the sensor and its surrounding area on
the bumper clean at all times.

GX 460 _O M_ OM6 0K 80 U_ (U)4-5. Using the driving support systems
The Blind Spot Monitor function uses rada
r 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 vehicles 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

CAUTION
■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 sa fe 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.

■The Blind Spot Monitor function is operational when
●The Blind Spot Monitor system 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*

• When there is a significant difference in height between your vehicle and the vehicle
that enters the detection area
• Directly after the Blind Spot Monitor system turned on
• When your vehicle is towing a trailer
●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.

The Rear Cross Traffic Alert functions when your vehicle is in reverse. It can
detect other vehicles approaching from the right or left rear of the vehicle. It uses
radar sensors to alert the driver of the other vehicle’s existence through flashing
the outside rear view mirror indicators and sounding a buzzer.

CAUTION
■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 Traffic Alert function is only an assist and is not a replacement for careful driv-
ing. Driver must be careful when backing up, even when using Rear Traffic Alert func-
tion. 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.

●The shift lever is in R.
●Vehicle speed is less than approximately 5 mph (8 km/h).

PCS (Pre-Collision system)∗
◆Pre-collision seat belts (front seat belts only)
If the system detects that a collision is unavoidable, the system will retract the
seat belt before the collision occurs.
The same will happen if the driver makes an emergency braking or loses con-
trol of the vehicle. (
→P. 2 9 )
However, when the VSC system is disabled, the system will not operate in the
event of skidding.
◆Pre-collision brake assist
When there is a high possibility of a frontal collision, the system applies
greater braking force in relation to how strongly the brake pedal is depressed.
◆Pre-collision braking
When there is a high possibility of a frontal collision, the system warns the
driver using a warning light, warning display and buzzer. If the system deter-
mines that a collision is unavoidable, the brakes are automatically applied to
reduce the collision speed. Pre-collision braking can be disabled using the
pre-collision braking off switch.
◆AVS (Adaptive Variable Suspension System) control (if equipped)
When the system determines that there is a high possibility of a frontal colli-
sion, the AVS optimizes the damping effect ( →P. 3 3 1 )
∗: If equipped
When the radar sensor detects possibility of a frontal collision, the pre-colli-
sion system such as the brakes and seat belts are automatically engaged to
lessen impact as well as vehicle damage.

◆Driver monitor system (if equipped)
When the system determines that there is a possibility of a collision with the
vehicle in front, and the driver is not
facing forward, PCS warnings are given in
advance to warn the driver. If the driver continues to not be facing forward,
and a high possibility of a collision with the vehicle in front is detected, PCS
informs the driver of high possibility of a collision with the vehicle in front by
performing slight braking to provide a physical warning (pre-collision alert
braking).

The “PCS” warning light turns on when
pre-collision braking is disabled.
