| [3] Models are LEV3-ULEV50-rated in all 50 states. |
| [4] 27 city/37 highway/31 combined mpg rating. Based on 2025 EPA mileage ratings. Use for comparison purposes only. Your mileage will vary depending on how you drive and maintain your vehicle, driving conditions and other factors. |
| [5] Based on SAE J1100 cargo volume measurement standard plus, where applicable, floor space between seating rows and seats in their forward-most and upright position. |
| [6] FCW cannot detect all objects ahead and may not detect a given object; accuracy will vary based on weather, speed and other factors. System operation affected by extreme interior heat. FCW does not include a braking function. Driver remains responsible for safely operating vehicle and avoiding collisions. |
| [7] CMBS cannot detect all objects ahead and may not detect a given object; accuracy will vary based on weather, speed and other factors. System operation affected by extreme interior heat. System designed to mitigate crash forces. Driver remains responsible for safely operating vehicle and avoiding collisions. |
| [8] LDW only alerts drivers when lane drift is detected without a turn signal in use. LDW may not detect all lane markings or lane departures; accuracy will vary based on weather, speed and road condition. System operation affected by extreme interior heat. Driver remains responsible for safely operating vehicle and avoiding collisions. |
| [9] Road Departure Mitigation only alerts drivers when lane drift is detected without a turn signal in use and can apply mild steering torque to assist driver in maintaining proper lane position and/or brake pressure to slow the vehicle's departure from a detected lane. RDM may not detect all lane markings or lane departures; accuracy will vary based on weather, speed and road condition. System operation affected by extreme interior heat. Driver remains responsible for safely operating vehicle and avoiding collisions. |
| [10] LKAS only assists driver in maintaining proper lane position when lane markings are identified without a turn signal in use and can only apply mild steering torque to assist. LKAS may not detect all lane markings; accuracy will vary based on weather, speed and road condition. System operation affected by extreme interior heat. Driver remains responsible for safely operating vehicle and avoiding collisions. |
| [11] ACC cannot detect all objects ahead and may not detect a given object; accuracy will vary based on weather, speed and other factors. ACC should not be used in heavy traffic, poor weather or on winding roads. ACC only includes a limited braking function. Driver remains responsible for slowing or stopping the vehicle to avoid a collision. |
| [12] TSR cannot detect all traffic signs and may misidentify certain signs. Accuracy will vary based on weather and other factors. System operation affected by extreme interior heat. Driver remains responsible for complying with all traffic regulations. |
| [13] The systems are not a substitute for your own visual assessment before changing lanes or backing up, and may not detect all objects, or provide complete information about conditions, behind or to the side of the vehicle. System accuracy will vary based on weather, size of object, and speed. Driver remains responsible for safely operating vehicle and avoiding collisions. |
| [14] Always visually confirm that it is safe to drive before backing up; the rearview camera display does not provide complete information about all conditions and objects at the rear of your vehicle. |
| [15] VSA is not a substitute for safe driving. It cannot correct the vehicle’s course in every situation or compensate for reckless driving. Control of the vehicle always remains with the driver. |
| [16] For optimal tire wear and performance, tire pressure should be checked regularly with a gauge. Do not rely solely on the monitor system. Please see your Honda dealer for details. |
