REFERENCE CHART

Vehicle Condition	Auto Cancel Condition	Fail-safe Deactivation Condition
CRUISE main indicator light blinks Master warning light comes on "Check Cruise System" is displayed "Pong" warning sound is heard	There is problem with millimeter wave radar sensor Beam axis of millimeter wave radar sensor deviates	Engine switch on (IG) again

Vehicle-to-vehicle distance control mode:

If the following conditions are detected while the dynamic radar cruise control system is in operation, the system maintains the stored vehicle speed in the ECM and cancels the dynamic radar cruise control operation.

REFERENCE CHART

Vehicle Condition	Auto Cancel Condition	Fail-safe Deactivation Condition
Master warning light comes on "Clean Radar Sensor" is displayed "Pong" warning sound is heard	There is dirt on millimeter wave radar sensor	Recover from condition on left (RESUME operation is possible after recovery)
Master warning light comes on "Cruise not Available" is displayed "Pong" warning sound is heard	Wiper switch is in HI position Millimeter wave radar sensor is least sensitive because of bad weather such as rain, fog, snow, and sandstorms	Recover from condition on left (RESUME operation is possible after recovery) Turn cruise control main switch ON again

Constant speed control mode and vehicle-to-vehicle distance control mode:

If the following conditions are detected while the dynamic radar cruise control system is in operation, the system clears the stored vehicle speed and cancels the dynamic radar cruise control operation.

REFERENCE CHART

Vehicle Condition	Auto Cancel Condition	Fail-safe Deactivation Condition
CRUISE main indicator light goes off	Vehicle speed is lower than low speed limit (approx. 40 km/h (25 mph)) while running with cruise control on Vehicle speed is lower than stored vehicle speed by 16 km/h (1.0 mph) or more while running with cruise control on	Push the cruise control main switch to RESUME/ACCEL
