The system has three alert stages for a possible collision. However, depending on circumstances, the CMBS™ may not go through all of the stages before initiating the last stage.
CMBS™ On and Off
Press and hold the button until the beeper sounds to switch the system on or off. When the CMBS™ is off:
The CMBS™ is turned on every time you start the engine, even if you turned it off the last time you drove the vehicle.
The CMBS™ may automatically shut off, and the CMBS™ indicator will come and stay on under certain conditions.
When the CMBS™ is activated, it will continue to operate even if the accelerator pedal is partially depressed. However, it will be canceled if the accelerator pedal is deeply depressed.
The indicators for the Adaptive Cruise Control (ACC) with Low Speed Follow, Road Departure Mitigation (RDM), Vehicle Stability Assist™ (VSA®) system, Vehicle Stability Assist™ (VSA®) OFF, low tire pressure/TPMS, Collision Mitigation Braking System™ (CMBS™ ), and Parking Brake and Brake System (Amber) may come on along with a message in the Driver Information Interface after reconnecting the battery. Drive a short distance at more than 12 mph (20 km/h). The indicator should go off. If it does not, have your vehicle checked by a dealer.
If the smart entry remote battery or the vehicle battery is dead, use the key instead of the smart entry remote.
Fully insert the key and turn it.
