When to Disable the Pre-Collision System (PCS) and not use Dynamic Radar Cruise Control (DRCC)
Introduction Pre-Collision System (PCS) with Automatic Emergency Braking (AEB) and Dynamic Radar Cruise Control utilize a forward-facing camera and millimeter wave radar that are carefully calibrated during the vehicle manufacturing process. Some vehicle operating conditions may influence the functionality of PCS and DRCC.
In the following situations, PCS should be disabled/set to off and DRCC should not be used:
• When the vehicle is driven in a sporty manner or off-road
• If the vehicle cannot be driven in a stable manner, such as when the vehicle has been in an accident or is malfunctioning
• When the vehicle is towing over the specified limit or is being towed
• After a strong impact has been applied to the front bumper or front grille, due to an accident or other reasons
• When vehicle angle/stance is changed, for example if the vehicle is towing or is loaded down with weight over the specified limit, or is lifted or lowered • When transporting the vehicle via truck, boat, train or similar means of transportation
• When accessories (such as snow removing equipment) that obstruct the front sensor to the vehicle are attached
• When inspecting the vehicle using a drum tester such as a chassis dynamometer or speedometer tester, or when using an onvehicle wheel balancer
• When a compact spare tire or an emergency tire puncture repair kit is used, tire chains are installed, or the tires are the incorrect size, not properly inflated or very worn
• When the vehicle is raised on a lift with the engine running and the tires are allowed to rotate freely
As a reminder, Toyota does not recommend vehicle modification which may affect these driver assistance systems (as noted in the vehicles Owner’s Manual).
Changing the PCS Default Setting
By default, PCS is set to “ON” after each ignition cycle. In certain situations, like some of those listed above, it may be necessary to operate the vehicle with PCS turned off. Customers that consistently operate their vehicle under these situations may want to change the PCS default setting. Performing the procedure in T-SB-0059-18 will change the PCS default setting from “ON” to retaining the PCS setting (“ON” or “OFF”) when the ignition was last turned off.
