WARNING
■Toyota Safety Sense P
The Toyota Safety Sense P is designed to operate under the assumption that the driver will drive safely, and is designed to help reduce the impact to the occupants and the vehicle in the case of a collision or assist the driver in normal driving conditions. As there is a limit to the degree of recognition accuracy and control perfor- mance that this system can provide, do not overly rely on this system. The driver is always responsible for paying attention to the vehicle’s surround- ings and driving safely.

■ If a warning message is displayed on the multi-information display
A system may be temporarily unavailable or there may be a malfunction in the system. ● In the following situations, perform the actions specified in the table. When
the normal operating conditions are detected, the message will disappear and the system will become operational.
If the message does not disappear, contact your Toyota dealer. Situation Actions
When the area around a camera is covered with dirt, moisture (fogged up, covered with con- densation, ice, etc.), or other for- eign matter
Using the wiper and A/C function, remove the dirt and other attached matter (P. 344).
When the temperature around the front camera is outside of the operational range, such as when the vehicle is in the sun or in an extremely cold environ- ment
If the front camera is hot, such as after the vehicle had been parked in the sun, use the air conditioning system to decrease the temperature around the front camera. If a sunshade was used when the vehicle was parked, depending on its type, the sunlight reflected from the surface of the sunshade may cause the temperature of the front camera to become excessively high. If the front camera is cold, such after the vehicle is parked in an extremely cold environment, use the air conditioning sys- tem to increase the temperature around the front camera.
The area in front of the front camera is obstructed, such as when the hood is open or a sticker is attached to the part of the windshield in front of the front camera.
Close the hood, remove the sticker, etc. to clear the obstruction.
When “Pre-Collision System Unavailable” is displayed
Check whether there is attached materi- als on the radar sensor and radar sensor cover, and if there is, remove it.

PCS (Pre-Collision System) The pre-collision system uses a radar sensor and front camera to detect vehicles and pedestrians in front of your vehicle. When the system determines that the possibility of a frontal collision with a vehicle or pedestrian is high, a warning operates to urge the driver to take evasive action and the potential brake pres- sure is increased to help the driver avoid the collision. If the sys- tem determines that the possibility of a frontal collision with a vehicle or pedestrian is extremely high, the brakes are automati- cally applied to help avoid the collision or help reduce the impact of the collision.
The pre-collision system can be disabled/enabled and the warning timing can be changed. (P. 259)
256 4-5. Using the driving support systems
SEQUOIA_OM_USA_OM0C047U
◆ Pre-collision warning
When the system determines that the possibility of a frontal collision is high, a buzzer will sound and a warning message will be displayed on the multi- information display to urge the driver to take evasive action.
◆ Pre-collision brake assist
When the system determines that the possibility of a frontal colli- sion is high, the system applies greater braking force in relation to how strongly the brake pedal is depressed.
◆ Pre-collision braking
When the system determines that the possibility of a frontal colli- sion is high, the system warns the driver. If the system determines that the possibility of a frontal collision is extremely high, the brakes are automatically applied to help avoid the collision or reduce the collision speed.
◆ Suspension control
When the system determines that the possibility of a frontal colli- sion is high, the Adaptive Variable Suspension System (P. 316) will control the damping force of the shock absorbers to help main- tain an appropriate vehicle posture.

WARNING
■Limitations of the pre-collision system
●The driver is solely responsible for safe driving. Always drive safely, taking care to observe your surroundings. Do not use the pre-collision system instead of normal braking operations under any circumstances. This system will not prevent collisions or lessen collision damage or injury in every situation. Do not overly rely on this sys- tem. Failure to do so may lead to an accident, resulting in death or serious injury.
●Although this system is designed to help avoid a collision or help reduce the impact of the collision, its effectiveness may change according to vari- ous conditions, therefore the system may not always be able to achieve the same level of performance. Read the following conditions carefully. Do not overly rely on this system and always drive carefully. • Conditions under which the system may operate even if there is no pos-
sibility of a collision: P. 263 • Conditions under which the system may not operate properly: P. 265
●Do not attempt to test the operation of the pre-collision system yourself. Depending on the objects used for testing (dummies, cardboard objects imitating detectable objects, etc.), the system may not operate properly, possibly leading to an accident.
■Pre-collision braking
●When the pre-collision braking function is operating, a large amount of
braking force will be applied. ● If the vehicle is stopped by the operation of the pre-collision braking func-
tion, the pre-collision braking function operation will be canceled after approximately 2 seconds. Depress the brake pedal as necessary.
●The pre-collision braking function may not operate if certain operations are performed by the driver. If the accelerator pedal is being depressed strongly or the steering wheel is being turned, the system may determine that the driver is taking evasive action and possibly prevent the pre-colli- sion braking function from operating.
● In some situations, while the pre-collision braking function is operating, operation of the function may be canceled if the accelerator pedal is depressed strongly or the steering wheel is turned and the system deter- mines that the driver is taking evasive action.
● If the brake pedal is being depressed, the system may determine that the driver is taking evasive action and possibly delay the operation timing of the pre-collision braking function.

WARNING
■When to disable the pre-collision system
In the following situations, disable the system, as it may not operate prop- erly, possibly leading to an accident resulting in death or serious injury: ●When the vehicle is being towed ●When your vehicle is towing another vehicle ●When transporting the vehicle via truck, boat, train or similar means of
transportation ●When the vehicle is raised on a lift with the engine running and the tires
are allowed to rotate freely ●When inspecting the vehicle using a drum tester such as a chassis dyna-
mometer or speedometer tester, or when using an on vehicle wheel bal- ancer
●When a strong impact is applied to the front bumper or front grille, due to an accident or other reasons
● If the vehicle cannot be driven in a stable manner, such as when the vehi- cle has been in an accident or is malfunctioning
●When the vehicle is driven in a sporty manner or off-road ●When the tires are not properly inflated ●When the tires are very worn ●When tires of a size other than specified are installed ●When tire chains are installed ●When a compact spare tire or an emergency tire puncture repair kit is used ● If equipment (snow plow, etc.) that may obstruct the radar sensor or front
camera is temporarily installed to the vehicle

■Operational conditions
The pre-collision system is enabled and the system determines that the pos- sibility of a frontal collision with a vehicle or pedestrian is high. Each function is operational at the following speeds: ●Pre-collision warning:
• Vehicle speed is between approximately 7 and 110 mph (10 and 180 km/h). (For detecting a pedestrian, vehicle speed is between approximately 7 and 50 mph [10 and 80 km/h].)
• The relative speed between your vehicle and the vehicle or pedestrian ahead is approximately 7 mph (10 km/h) or more.
●Pre-collision brake assist: • Vehicle speed is between approximately 20 and 110 mph (30 and 180 km/h).
(For detecting a pedestrian, vehicle speed is between approximately 20 and 50 mph [30 and 80 km/h].)
• The relative speed between your vehicle and the vehicle or pedestrian ahead is approximately 20 mph (30 km/h) or more.
●Pre-collision braking: • Vehicle speed is between approximately 7 and 110 mph (10 and 180 km/h).
(For detecting a pedestrian, vehicle speed is between approximately 7 and 50 mph [10 and 80 km/h].)
• The relative speed between your vehicle and the vehicle or pedestrian ahead is approximately 7 mph (10 km/h) or more.
The system may not operate in the following situations: ● If a battery terminal has been disconnected and reconnected and then the
vehicle has not been driven for a certain amount of time ● If the shift lever is in R ● If VSC is disabled (only the pre-collision warning function will be opera-
tional) ● If the low speed four-wheel drive indicator is illuminated (only the pre-colli-
sion warning function will be operational)

■Pedestrian detection function
■Cancelation of the pre-collision braking
If either of the following occur while the pre-collision braking function is oper- ating, it will be canceled: ●The accelerator pedal is depressed strongly. ●The steering wheel is turned sharply or abruptly.
The pre-collision system detects pedestri- ans based on the size, profile, and motion of a detected object. However, a pedes- trian may not be detected depending on the surrounding brightness and the motion, posture, and angle of the detected object, preventing the system from operating properly. (P. 267)
■Conditions under which the system may operate even if there is no pos- sibility of a collision
● In some situations such as the following, the system may determine that
there is a possibility of a frontal collision and operate. • When passing a vehicle or pedestrian • When changing lanes while overtaking a preceding vehicle • When overtaking a preceding vehicle that is changing lanes
