CAUTION
■Handling the radar sensor
One Blind Spot Monitor sensor is installed inside the left and right side of the vehi-
cle rear bumper respectively. Observe the following to ensure the Blind Spot
Monitor system can function correctly.
●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 sur-
rounding area is subject to a strong im pact, 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.

4-5. Using the driving support systems
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 out-
side 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) for-
ward of the rear bumper

■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 design ed to detect the following types of vehi-
cles and/or objects:
●Small motorcycles, bicycles, pedestrians etc.*
●Vehicles traveling in the opposite direction
●Guardrails, walls, signs, parked vehi cles 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.
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 blin d 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.

■Conditions under which the Blind Spot Monitor function may not function cor-
rectly
●The Blind Spot Monitor function may not de tect vehicles correctly in the following
conditions:
• 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 detect ion 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 are installed on the rear of the vehicle
●Instances of the Blind Spot Monitor functi on 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 vehi- cle
• When vehicle lanes are narrow and a ve hicle driving 2 lanes across from your
vehicle enters the detection area
• When items such as a bicycle carrier are 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 exist-
ence through flashing the outside rear view mirror indicators and sound-
ing 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 Cross Traffic Alert function is only an assist and is not a replacement for
careful driving. Driver must be careful when backing 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 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.

4-5. Using the driving support systems
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).

Hybrid vehicle driving tips (hybrid vehicles)
When using Eco drive mode, the torque corresponding to the accelerator
pedal depression amount can be generated more smoothly than it is in
normal conditions. In addi tion, the operation of the air conditioning system
(heating/cooling) will be minimized, improving the fuel economy.
( P. 311)
The Eco-friendly driving is possible by keeping the indicate of Hybrid Sys-
tem Indicator within Eco area. ( P. 100)
Make sure to operate the brakes gently and in good time. A greater
amount of electrical energy can be retained when slowing down.
Repeated acceleration and deceleration , as well as long waits at traffic
lights, will lead to bad fuel consumpti on. Check traffic reports before leav-
ing and avoid delays as much as possible. When encountering a delay,
gently release the brake pedal to allow the vehicle to move forward
slightly while avoi ding overuse of the accelerator pedal. Doing so can help
control excessive gasoline consumption.
For economical and ecological drivin g, pay attention to the following
points:

Control your speed and keep at a constant speed. Also, before stopping
at a toll booth or similar, allow plenty of time to release the accelerator and
gently apply the brakes. A greater am ount of electrical energy can be
retained when slowing down.
Use the air conditioning only when ne cessary. Doing so can help control
excessive gasoline consumption.
In summer: In high temperatures, use th e recirculated air mode. Doing so
will help to reduce the burden on th e air conditioner and reduce fuel con-
sumption as well.
In winter: Because the gasoline engine will not automatically cut out until
the gasoline engine and the interior of the vehicle are warm, it will con-
sume fuel. Also, fuel consumption can be improved by avoiding overuse of
the heater.
Make sure to check the tire inflati on pressure frequently. Improper tire
inflation pressure can cause poor fuel consumption.
Also, as snow tires can cause large am ounts of friction, their use on dry
roads can lead to poor fuel consumptio n. Use a tire that is appropriate for
the season.
Carrying heavy luggage can lead to poor fuel consumption. Avoid carry-
ing unnecessary luggage. Installing a la rge roof rack can also cause poor
fuel consumption.

4-6. Driving tips
Since the gasoline engine starts up and cuts out automatically when cold,
warming up the engine is unnecessary. Moreover, frequently driving short
distances will cause the engine to repeatedly warm up, which can lead to
poor fuel consumption.
Warming up before driving
