[3]  Trims are LEV3-SULEV30-rated in California and states that have adopted California vehicle emission regulations. Trims in non-CARB states are LEV3-ULEV125-rated.
[4]  30 city/38 highway/33 combined mpg rating for LX and Touring trims. 29 city/37 highway/32 combined mpg rating for Sport trim. 32 city/42 highway/36 combined mpg rating for EX & EX-L trims. Based on 2021 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]  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.
[6]  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.
[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]  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.
[9]  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.
[10]  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.
[11]  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.
[12]  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.
[13]  ACC with Low-Speed Follow 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. Driver remains responsible for safely operating vehicle and avoiding collisions.
[14]  Display accuracy will vary based on weather, size of object and speed, and the display may not show all relevant traffic. The display is not a substitute for your own direct visual assessment of traffic conditions before changing lanes.
