Understanding Trim Levels and Packages
Why Trim Level Matters
Many vehicles only include ACC and Lane Assist on higher trim levels or as optional packages. The same model year and model can have different compatibility depending on the trim.Example: 2022 Honda Civic
Example: 2022 Honda Civic
- Sport Trim: May not include Honda Sensing as standard
- EX Trim and above: Honda Sensing is standard (includes ACC + LKAS)
- All 2022 Civics with Honda Sensing are compatible
Example: 2020 Hyundai Elantra
Example: 2020 Hyundai Elantra
- SE/SEL Trim: May not include Smart Cruise Control
- SEL with Convenience Package: Adds Smart Cruise Control + Lane Keeping
- Limited/Ultimate Trim: Smart Cruise Control is standard
- Only Elantras with SCC are compatible
How to Verify Your Trim
Check Your Owner's Manual
Look for the features section to see if ACC and Lane Assist are listed as equipped.
Check the Window Sticker
Your vehicle’s original window sticker (Monroney label) lists all installed packages and features.
Testing Your Vehicle
Testing ACC Functionality
Enable ACC
On a highway or road with light traffic, enable your vehicle’s ACC system. This is typically done via buttons on the steering wheel.
Set Speed and Following Distance
Set your desired speed (e.g., 65 mph) and following distance (usually 3-4 car lengths).
Approach Traffic
Drive up behind slower-moving traffic. Your vehicle should automatically slow down to maintain the set following distance.
Some vehicles have ACC that only works above certain speeds (e.g., 25 mph). This is still compatible with sunnypilot, but may have limitations in stop-and-go traffic.
Testing Lane Assist Functionality
Enable Lane Assist
On a highway with clear lane markings, enable your vehicle’s lane keeping/centering system.
Feel for Steering
You should feel the system making small steering corrections to keep the vehicle centered.
