    Cruise Control Indicator Light

    (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.

    Tech Tips

    During constant speed control mode, the cruise control indicator light (constant speed control mode) flashes. During vehicle-to-vehicle distance control, the cruise control indicator light (vehicle-to-vehicle distance control mode) flashes.

    Vehicle Condition Auto Cancel Condition Fail-safe Deactivation Condition

    • Cruise control indicator light blinks

    • Master warning light comes on

    • "CHECK CRUISE CONTROL SYSTEM" is displayed

    • "Pong" warning sound is heard

    • Open or short in stop light switch circuit

    • Problem with vehicle speed signal

    		 Cruise control system is turned off and back on again using the cruise control switch (ON-OFF button).

    Cruise Control Indicator Light

    (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 blinks

    • Master warning light comes on

    • "CLEAN RADAR SENSOR" is displayed

    • "CRUISE CONTROL NOT AVAILABLE" is displayed

    • "Pong" warning sound is heard

    • There is dirt on millimeter wave radar sensor

    • Wipers operating on HI setting

    • Millimeter wave radar sensor sensitivity reduced because of bad weather such as rain, fog, snow, or sandstorm

    		 Cruise control system is turned off and back on again using the cruise control switch (ON-OFF button).

  4. 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 remains illuminated Vehicle speed is lower than stored speed by approximately 16 km/h (10 mph) or more Cruise control switch is pushed -/SET

  5. 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 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 remains illuminated Vehicle speed is lower than low speed limit Recover from condition on left (RESUME operation is possible after recovery)
