Switching modes

The mode cannot be switched to constant speed control mode if vehicle-to-vehicle

constant speed control to vehicle-to-vehicle distance control mode. Turn the sys-

tem off by pressing the “ON-OFF” button, and turn it on again.

Accelerating

The vehicle can accelerate normally. After acceleration, the set speed resumes.

However, during vehicle-to-vehicle distance control mode, the vehicle speed may

decrease below the set speed in order to maintain the distance to the vehicle

ahead.

■

Vehicle-to-vehicle distance control driving is automatically canceled in the follow-

ing situations:

●

Actual vehicle speed falls below approximately 25 mph (40 km/h).

●

VSC is activated.

●

The sensor cannot operate correctly because it is covered in some way.

●

The windshield wipers are operating at high speed.

●

The driving mode select switch is set to second start mode.

●

The switching operation continues for 5 seconds or more after the center dif-

ferential lock switch has been operated.

If vehicle-to-vehicle distance control driving is automatically canceled for any other

reason, there may be a malfunction in the system. Contact your Lexus dealer.
