ADAPTIVE SPEED LIMITER LIMITATIONS

The adaptive speed limiter does not operate if the traffic sign recognition system is unavailable. If the adaptive speed limiter is unavailable the system reverts to standard speed limiter operation using the last detected speed limit. See SPEED LIMITER OVERVIEW.

The adaptive speed limiter:

  • Does not recognize speed limits below 3 mph (5 km/h). For detected speed limits below 10 mph (16 km/h), the system sets a speed limit of 10 mph (16 km/h).

  • May allow vehicle speed to increase in certain conditions, e.g., when traveling downhill. If the vehicle’s speed rises by more than 2 mph (3.5 km/h) above the detected speed limit, the instrument panel displays a warning message. If the vehicle’s speed rises by more than 5 mph (7 km/h) above the detected speed limit for 4 seconds, a chime also sounds.

  • Performance and accuracy are only as good as the information provided by the traffic sign recognition system and the navigation system. Always make sure the navigation system is operating correctly and is using the latest software.

The instrument panel displays messages to inform the driver of any performance or system issues.
