Toyota CH-R: Situations in which the system may not operate properly

• In certain situations, such as the following, a detectable object may not be detected by the front sensors, and the system may not operate properly:

• When a detectable object is approaching your vehicle
• When your vehicle or a detectable object is wandering
• When a detectable object makes an abrupt maneuver (such as sudden swerving, acceleration or deceleration)
• When suddenly approaching a detectable object
• When the detectable object is near a wall, fence, guardrail, manhole cover, steel plate on the road surface, or another vehicle
• When there is a structure above a detectable object
• When part of a detectable object is hidden by another object (large luggage, umbrella, guardrail, etc.)
• When multiple detectable objects are overlapping
• When a bright light, such as the sun, is reflecting off of a detectable object
• When a detectable object is white and looks extremely bright
• When the color or brightness of a detectable object causes it to blend in with its surroundings
• When a detectable object cuts in front of or suddenly emerges in front of your vehicle
• When approaching a vehicle which is diagonal
• If a bicycle is a child sized bicycle, is carrying a large load, is carrying an extra passenger, is carrying a forward leaning rider, or has an unusual shape (bicycles equipped with a child seat, tandem bicycles, etc.)
• If a pedestrian or bicycle is shorter than approximately 1 m (3.2 ft.) or taller than approximately 2 m (6.5 ft.).
• When the silhouette of a pedestrian or bicycle is unclear (such as when they are wearing a raincoat, long skirt, etc.)
• When a pedestrian is bending forward or squatting
• When a pedestrian or bicycle is moving at high speed
• When a pedestrian is pushing a stroller, wheelchair, bicycle or other vehicle
• When a detectable object blends in with the surrounding area, such as when it is dim (at dawn or dusk) or dark (at night or in a tunnel)
• When the vehicle has not been driven for a certain amount of time after the hybrid system was started
• While turning left/right or a few seconds after turning left/right
• While driving around a curve and a few seconds after driving around a curve
• When turning left/right and an oncoming vehicle is driving in a lane 3 or more lanes from the vehicle
• When turning left/right and the direction of the vehicle differs greatly from the direction traffic flows in the oncoming lane

• When turning left/right, a pedestrian or bicycle behind the vehicle comes in front of it as if it overtakes the vehicle

• When at an intersection, the approaching crossing vehicle is long in overall length, such as a large truck, towing trailer, etc.

• In addition to the preceding, in certain situations, such as the following, the emergency steering assist may not operate properly:

• When a detectable object is too close to the vehicle
• When there is insufficient space to perform evasive steering maneuvers or an obstruction exists in the evasion direction
• When there is an oncoming vehicle

• In addition to the preceding, in certain situations, such as the following, walls may not be detected as a target object and the Acceleration Suppression at Low Speed function may not operate properly:

• When scenery behind the wall is visible, such as a glass door, grid fence, etc.
• When the wall is slanted or low
• When the wall is narrow, such as a pole, etc.
• When the wall is made of plants, such as a hedge, etc.
• When the road, etc. is reflected on the wall
• When the vehicle is approaching the wall at an angle

Changing the pre-collision setting

• The pre-collision system can be enabled/disabled through a customize setting.

The system is enabled each time the power switch is turned to ON.

• When the system is disabled, the PCS warning light will illuminate and a message will be displayed on the multi-information display.
• The pre-collision setting can be changed on the customize settings.
• Vehicles without active steering function: When the pre-collision warning timing is changed, the emergency steering assist timing will also be changed.

  When "Later" is selected, the emergency steering assist (excluding the active steering function) will not operate in most cases.

• Vehicles with active steering function: When the pre-collision warning timing is changed, the emergency steering assist (excluding the active steering function) timing will also be changed.

  When "Later" is selected, the emergency steering assist (excluding the active steering function) will not operate in most cases.

• Vehicles with a driver monitor camera: When the system determines that the driver is not facing forward, the pre-collision warning and emergency steering assist will operate at the "Earlier" timing, regardless of the user setting.
• When the dynamic radar cruise control is operating, the pre-collision warning will operate at the "Earlier" timing, regardless of the user setting.
