Fail-Safe Chart [10/2014 - 09/2017]
- Constant speed control mode and vehicle-to-vehicle distance control mode:
If any of the following auto cancel conditions are detected while the dynamic radar cruise control system is controlling vehicle speed, the system clears the stored vehicle speed and cancels control of vehicle speed by the dynamic radar cruise control system.
Vehicle Condition Auto Cancel Condition Fail-safe Deactivation Condition - Cruise control indicator light goes off

Engine switch is turned off and back on (IG) again. - *: For details, refer to CAN communication system information.
- Vehicle-to-vehicle distance control mode:
If any of the following auto cancel conditions are detected while the dynamic radar cruise control system is controlling vehicle speed, the system maintains the stored vehicle speed in memory and cancels control of vehicle speed by the dynamic radar cruise control system.
Vehicle Condition Auto Cancel Condition Fail-safe Deactivation Condition - Cruise control indicator light goes off

- "Pong" warning sound is heard
There is dirt on millimeter wave radar sensor Cruise control system is turned off and back on again using the cruise control main switch. - Cruise control indicator light goes off
- A warning message "CRUISE NOT AVAILABLE" is displayed
- "Pong" warning sound is heard
- Wipers operating on HI setting
- Millimeter wave radar sensor sensitivity reduced because of bad weather such as rain, fog, snow, or sandstorm
- Constant speed control mode:
If the following auto cancel condition is detected while the dynamic radar cruise control system is controlling vehicle speed, the system clears the stored vehicle speed and cancels control of vehicle speed by the dynamic radar cruise control system.
Vehicle Condition Auto Cancel Condition Fail-safe Deactivation Condition Cruise control indicator light is on Vehicle speed is lower than stored vehicle speed by approximately 16 km/h (10 mph) or more Cruise control main switch is pushed -SET - Constant speed control mode and vehicle-to-vehicle distance control mode:
If the following auto cancel condition is detected while the dynamic radar cruise control system is controlling vehicle speed, the system maintains the stored vehicle speed in memory and cancels control of vehicle speed by the dynamic radar cruise control system.
Vehicle Condition Auto Cancel Condition Fail-safe Deactivation Condition Cruise control indicator light is on Vehicle speed is lower than low speed limit (approximately 40 km/h [25 mph]) while driving with cruise control system controlling vehicle speed Push the cruise control main switch to +RES
