■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 sys-
tem 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 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 su rrounding area on the bumper.
●Do not paint the rear bumper any color other than an official Lexus color.
●Keep the sensor and its surrounding area on
the bumper clean at all times.

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 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

■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 supp lementary 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 judg e 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 does have operational limitations. Therefore the
driver’s own visual confirmation of safety is necessary.

■The Blind Spot Monitor function is operational when
●The BSM main switch is set to 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 Bl ind Spot Monitor function may not function correctly
●The Blind Spot Monitor function may not dete ct 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 main switch is set to on
• When items such as a bicycle carrier ar e installed on the rear of the vehicle
●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 ar e installed on the rear of the vehicle

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.

■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. Driver must be careful when ba cking up, even when using 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 pedestrian s, 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 areas that vehicles can be detected in are outlined below.
To give the driver a more consistent time to react, the buzzer can alert for faster
vehicles from farther away.
Example:
■The Rear Cross Traffic Alert function is operational when
●The BSM main switch is set to on.
●The shift lever is in R.
●Vehicle speed is less than approximately 5 mph (8 km/h).
●Approaching vehicle speed is between approximately 5 mph (8 km/h) and 18 mph (28
km/h).

c Alert function will not detect a vehicle

Driving assist systems
◆ABS (Anti-lock Brake System)
Helps to prevent wheel lock when the brakes are applied suddenly, or if the
brakes are applied while drivin
g on a slippery road surface
◆Brake assist
Generates an increased level of braking force after the brake pedal is
depressed when the system detects a panic stop situation
◆VSC (Vehicle Stability Control)
Helps the driver to control skidding when swerving suddenly or turning on
slippery road surfaces
◆Enhanced VSC (Enhanced Vehicle Stability Control)
Provides cooperative control of the ABS, TRAC, VSC and EPS.
Helps to maintain directional stability when swerving on slippery road sur-
faces by controlling steering performance.
◆TRAC (Traction Control)
Helps to maintain drive power and prevent the drive wheels from spinning
when starting the vehicle or accelerating on slippery roads
◆Hill-start assist control
Helps to prevent the vehicle from rolling backward when starting on an
incline.
To help enhance driving safety and performance, the following systems oper-
ate automatically in response to various driving situations. Be aware, however,
that these systems are supplementary and should not be relied upon too
heavily when operating the vehicle.

◆EPS (Electric Power Steering)
Employs an electric motor to reduce the
amount of effort needed to turn the
steering wheel
The slip indicator light will flash while
the TRAC/VSC systems are operating.
If the vehicle gets stuck in mud, dirt or snow, the TRAC system may reduce
power from the engine to the wheels. Pressing to turn the system off
may make it easier for you to rock the vehicle in order to free it.
To turn the TRAC system off, quickly
press and release .
The “Traction Control Turned Off” will
be shown on the multi-information dis-
play. Press again to turn the sys-
tem back on.
