If a vehicle ahead is traveling at an extremely low speed, the system may not detect it
correctly.
If there is a structure on the road or an object (such as a monorail) at a low height off the
ground in front of the vehicle, the system may operate. Therefore, do not use the TJA.

causing you to close in on the vehicle rapidly, accelerate using the accelerator pedal or
