■Obstacles not detected
The sensor cannot detect plastic obstacles such as traffic cones. There may also be occa-
sions when the sensor cannot detect pedestri ans, animals, bicycles, motorcycles, trees,
or snowdrifts.
■Situations in which the pre-crash safe ty system does not function properly
The system may not function effectively in situations such as the following:
●On roads with sharp bends or uneven surfaces
●If a vehicle suddenly moves in front of your vehicle, such as at an intersection
●If a vehicle suddenly cuts in front of your vehicle, such as when overtaking
●In inclement weather such as heavy rain, fog, snow or sand storms
●If the vehicle is skidding when VSC is not operating
●When your vehicle is steeply inclined
●When only part of your vehicle’s front end collides with, or contacts, a vehicle or object
in a frontal collision
●When the radar sensor moves off position due to its surrounding area being subjected
to a strong impact
●When an obstacle suddenly appears in front of the vehicle due to the steering wheel
being turned sharply or another cause
■Automatic cancelation of the pre-crash safety system
When a malfunction occurs due to sensor contamination, etc. that results in the sensors
being unable to detect obstacles, the pre-crash safety system will be automatically dis-
abled. In this case, the system will not activa te even if there is a collision possibility.
■When there is a malfunction in the system or if the system is temporarily unusable
The pre-crash safety system warning light will flash and warning messages will be dis-
played. ( →P. 5 2 2 , 5 3 3 )

CAUTION
■Limitations of the pre-crash safety system
●The driver is solely responsible for safe driving. Always drive safely, taking care to
observe your surroundings.
Do not use the pre-crash safety system instead of normal braking operations under
any circumstances. This system will not prevent collisions or lessen damage or inju-
ries in all cases. Do not overly rely on this system. Failure to do so may cause an acci-
dent, resulting in death or serious injury.
This system has been designed to help avoid and reduce the impact of collisions.
However, the system operates differently depending on the situation ( →P. 3 0 4 ,
305). As a result, the same level of performance may not be expected in all cases.
Also, the pre-crash safety brakes may not operate if the driver is depressing the
brake pedal or turning the steering wheel, as the system will determine such condi-
tions as collision avoidance operations.
●As the pre-crash safety system is designed to assist the driver in safe driving, it may
operate under sporty driving conditions, which may cause an accident. For this rea-
son under sporty driving conditions, it is recommended that this system be disabled
by using the PCS OFF switch.
■Handling the radar sensor
Observe the following to ensure the pre-cras h safety system can function effectively.
Otherwise, the system may not function correctly and could result in an accident.
●Keep the sensor and grille cover clean at all times.
Clean the sensor and grille cover with a soft cloth so you do not mark or damage
them.
●Do not subject the sensor or surrounding area to a strong impact.
If the sensor moves even slightly off position, the system may become inaccurate or
malfunction. If the sensor or surrounding area is subject to a strong impact, always
have the area inspected and adjusted by any authorized Lexus dealer or repairer, or
another duly qualified and equipped professional.
●Do not disassemble the sensor.
●Do not attach accessories or stickers to the sensor, grille cover or surrounding area.
●Do not modify or paint the sensor and grille cover.
●If the radar sensor needs to be replaced, contact any authorized Lexus dealer or
repairer, or another duly qualified and equipped professional.

CAUTION
■Cautions regarding the assist contents of the system
By means of alarms and brake control, the pre-crash safety system is intended to assist
the driver in avoiding collisions through the process of LOOK-JUDGE-ACT. There are
limits to the degree of assistance the system can provide, so please keep in mind the
following important points.
●Assisting the driver in watching the road
The pre-crash safety system is only able to detect obstacles directly in front of the
vehicle, and only within a limited range. It is not a mechanism that allows careless or
inattentive driving, and it is not a system th at can assist the driver in low-visibility con-
ditions. It is still necessary for the driver to pay close attention to the vehicle’s sur-
roundings.
●Assisting the driver in making correct judgment
When attempting to estimate the possibility of a collision, the only data available to
the pre-crash safety system is that from obstacles it has detected directly in front of
the vehicle. Therefore, it is absolutely nece ssary for the driver to remain vigilant and
to determine whether or not there is a possibility of collision in any given situation.
●Assisting the driver in taking action
The pre-crash safety system’s braking assist feature is designed to help reduce the
severity of a collision, and so only acts when the system has judged that a collision is
unavoidable. This system is not capable of automatically avoiding a collision or bring-
ing the vehicle to a stop safely without appropriate operations performed by the
driver. For this reason, when encountering a dangerous situation the driver must take
direct and immediate action in order to ensure the safety of all involved.

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 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 any authorized Lexus
dealer or repairer, or another duly qualified and equipped professional.
●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.

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 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.

IS300h_EE(OM53D56E)4-6. Driving tips
■Using Eco drive mode
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 addition, the operation of the air conditioning system (heating/
cooling) will be minimized, improving the fuel economy. (
→P. 2 9 3 )
■Use of Hybrid System Indicator
Eco-friendly driving is possible by keeping the indicator needle (except F
SPORT models) or bar display (F SPORT models) of Hybrid System Indicator
within the Eco area. ( →P. 1 1 3 )
■When braking
Make sure to operate the brakes gently and in good time. A greater amount
of electrical energy can be regenerated when slowing down.
■Delays
Repeated acceleration and deceleration, as well as long waits at traffic lights,
will lead to bad fuel economy. Check traffic reports before leaving and avoid
delays as much as possible. When driving in a traffic jam, gently release the
brake pedal to allow the vehicle to move forward slightly while avoiding over-
use of the accelerator pedal. Doing so can help control excessive gasoline
consumption.
■Highway driving
Control your speed and keep at a constant speed. Before stopping at a toll
booth or similar, allow plenty of time to release the accelerator and gently
apply the brakes. A greater amount of electrical energy can be regenerated
when slowing down.
