WARNING
●The shape of an object may prevent the sensor from detecting it. Pay particular atten- tion to the following:
• Wires, fences, ropes, etc.
• Cotton, snow and other materials that absorb sound waves • Sharply-angled objects•Low objects
• Tall objects with upper sections projecting outwards in the direction of your vehi- cle• People, animals and other moving objects
• People wearing certain types of clothing
●The following situations may occur when using the Lexus parking assist-sensor.
• Depending on the shape of the object and other factors, the detection distance may be shortened, or detection may not be possible.• Objects may not be detected if they are too close to a sensor.
• There will be a short delay between the de tection of an object and display of the detection. Even at slow speeds, there is a possibility that the object will come within a sensor’s detection area before the display is shown and a warning beep
sounds. • Thin posts or objects lower than a sensor may not be detected when approached,even if they have been detected once.
• It might be difficult to hear beeps due to the volume of the audio system or air flow noise of the air conditioning system.
NOTICE
■When using Lexus parking assist-sensor
In the following situations, the system may not function correctly due to a sensor mal-
function etc. Have the vehicle checked by any authorized Lexus dealer or repairer, or another duly qualified and equipped professional.
●The Lexus parking assist-sensor operation display flashes, and a beep sounds when
no obstacles are detected.
●If the area around a sensor collides with something, or is subjected to strong impact.
●If the bumper or grille collides with something.
●If the display shows continuously without beeping, except when the switch has been turned on.
●If a display error occurs, first check the sensor.
If the error occurs even when there is no ice, snow or mud on the sensor, it is likely that the sensor is malfunctioning.
■Notes when washing the vehicle
Do not apply intensive bursts of water or steam to the sensor area.
Doing so may result in the sensor malfunctioning.

WARNING
■When using the Lexus parking assist monitor system
The parking assist monitor is a supplemental device intended to assist the driver when backing up. When backing up, be sure to check visually behind and all around the vehi-
cle before proceeding.
Observe the following precautions to avoid an accident that could result in death or serious injuries.
●Never depend on the parking assist monitor entirely when backing up. The imageand the position of the guide lines displayed on the screen may differ from the actualstate.
Use caution, just as you would when backing up any vehicle.
●Be sure to back up slowly, depressing the brake pedal to control vehicle speed.
●If you seem likely to hit nearby vehicles , obstacles, people or mount the shoulder,
depress the brake pedal to stop the vehicle.
●The instructions given are only guidelines.
When and how much to turn the steering wheel will vary according to traffic condi-
tions, road surface conditions, vehicle condition, etc. when parking. It is necessary to be fully aware of this before using the parking assist system.
●When parking, be sure to check that th e parking space will accommodate your vehi-
cle before maneuvering into it.
●Do not use the parking assist monitor in the following cases:
• On icy or slick road surfaces, or in snow
• When using tire chains or emergency tires • When the trunk is not closed completely• On roads that are not flat or straight, such as curves or slopes.
●In low temperatures, the screen may darken or the image may become faint. Theimage could distort when the vehicle is moving, or you may become unable to see the
image on the screen. Be sure to check direct visually and with the mirrors all around the vehicle before proceeding.
●If the tire sizes are changed, the position of the guide lines displayed on the screen
may change.

Eco drive mode
Helps the driver accelerate in an eco-friendly manner and improve fuel econ-
omy through moderate throttle characteristics and by controlling the opera-
tion of the air conditioning system (heating/cooling).
When not in Eco drive mode, if the driving mode select switch is turned to the left, the Eco drive mode indicator will come on.

WARNING
■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 in stead of normal braking operations under any circumstances. This system will not pr event 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 differe ntly depending on the situation (P. 313). As a
result, the same level of performance may no t be expected in all cases. Also, the pre- crash safety brakes may not operate if th e driver is depressing the brake pedal or turning the steering wheel, as the system will determine such conditions 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-crash 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 po sition, the system may become inaccurate or malfunction. If the sensor or surrounding area is subject to a strong impact, alwayshave the area inspected and adjusted by an y authorized Lexus dealer or repairer, or
another duly qualified an d 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.
