Symptoms
- Backup camera shows video but no colored guide lines
- Guidelines are present but clearly off to one side
- Lines don't move correctly when steering
- Problem started after a windshield, bumper, or camera replacement
Likely causes
- CommonGuidelines turned off in settingsSome systems let you toggle dynamic guidelines on or off in the camera settings menu.
- CommonCamera not recalibrated after replacement or bumper workA newly installed or repositioned camera often needs a calibration procedure to align the guidelines correctly.
- PossibleSoftware glitch in the guideline overlayA display bug can cause the overlay to stop rendering even though the camera feed works.
- Less commonSteering angle sensor issueOn systems with dynamic (moving) guidelines, a sensor problem can prevent the lines from tracking properly.
What to do
- Check the infotainment settings menu for a backup camera or guideline toggle and make sure it's enabled.
- If the camera was recently replaced or the bumper was repaired, note that a professional calibration may be required.
- Restart the car's infotainment system to rule out a temporary display glitch.
- Test whether the lines move at all when turning the steering wheel, which indicates whether it's a static or dynamic guideline system.
- Compare the guideline position to where the car is actually going in a safe, open area at low speed.
- If lines are present but clearly misaligned, avoid relying on them until they're recalibrated.
When to call a pro
After any bumper or camera replacement, have the shop or dealer perform the manufacturer's camera calibration procedure.
