What is the Honda Collision Mitigation Braking System (CMBS)? CMBS is a feature included with the Honda Sensing suite of safety and driver-assistive technologies. But what are driver-assistive features? This technology relies on a host of cameras, sensors, and radar to help with driver awareness. Honda’s CMBS can actually help bring your vehicle to a stop by automatically applying the brakes if the system deems that a collision is inevitable.
Uses a front camera near the mirror and a radar unit in the grille to track objects and distance ahead.
Alerts with dash icons and beeps if a lane-ahead object is detected and closing speed rises.
Three stages: alert → light brake assist → automatic braking when impact risk is high.
Important note: CMBS helps assist drivers. It can’t prevent every event, and road, weather, or speed can affect performance. The driver stays responsible.
While Honda’s CMBS can help you avoid a frontal collision with other vehicles, pedestrians, cyclists, and other objects, you might want to adjust the distance setting that determines when the system will intervene. If a potential front collision is detected, CMBS has three stages of alert. First, a visual alert will appear in the driver information interface accompanied by a series of beeps. Second, if there is no input from the driver, the visual and audible notifications will continue and light braking will be applied. Third, if there is still no response from the driver and a frontal collision is inevitable, CMBS will strongly apply the brakes.
If you want to change the distance setting of your Collision Mitigation Braking System simply follow the steps below:
Park the car.
Home → Settings → Vehicle.
Driver Assist System Setup.
Forward Collision Warning Distance.
Choose Long, Normal, or Short.
Back to exit.
(Names can vary by model and head unit.)
Honda doesn’t recommend turning off CMBS, but drivers who wish to disable this Honda Sensing feature have the capability to do so. If you want to turn off CMBS just press and hold down the CMBS button located to the left of the steering column until you hear a beep and a confirmation message displays in the vehicle’s Driver Information Interface. CMBS will now be shut down until you turn off the ignition. Keep in mind, however, that CMBS will be active the next time you start your Honda vehicle—by default.
Almost every new Honda vehicle comes standard with the Collision Mitigation Braking System. Continue reading to find out which trim levels come standard with CMBS.

Helps protect occupants by cutting crash risk or severity when events occur.
Pairs with Road Departure Mitigation, Lane Keeping Assist, and other features for broader coverage across your lane and roadway.
Supports confidence on test drives at our dealership and after purchase.
Not all automotive collisions are avoidable, but wouldn’t you like to decrease your odds as much as possible? Honda’s CMBS is an intuitive driver-assist feature that will help prevent frontal collisions by utilizing audio alerts, visual notifications, and braking assistance.

It monitors speed, object type, and distance. If closing rate spikes, alerts start first. If there’s no driver input and impact looks likely, the system adds brake assist then strong braking.
Yes. CMBS handles frontal events. Road Departure Mitigation helps when the vehicle drifts across lines. Together they assist drivers across more scenarios.
You can switch it off, but Honda recommends leaving it on. It restarts at the next key cycle. CMBS is one part of Honda Sensing that can lower the likelihood of a crash.
Honda lists Honda Sensing as standard for current 2025–2026 vehicles, so CMBS is included from base trims up.
No system can. CMBS helps reduce impact when a crash might happen and supports the driver when reaction time is short. The driver stays in control.
