2016–2020 Cadillac CT6 FAQ
What symptoms mean the cabin air filter may need replacement?
2017–2020
Replace it sooner if airflow is reduced, windows fog, or odors develop; a GM dealer can help determine when.
Page 363 in the 2020 manual →2016
Reduced airflow, window fogging, or odors may indicate that the passenger compartment air filter needs replacement.
Page 350 in the 2016 manual →When do the automatic headlights turn on?
2017–2020
With the exterior lamp control in AUTO, the headlamps turn on automatically when it is dark enough outside; do not cover the instrument-panel light sensor.
Page 153 in the 2020 manual →Why does the exterior-lamps warning chime sound?
2017–2020
The warning chime sounds when the driver door opens while the ignition is off and the exterior lamps remain on.
Page 152 in the 2020 manual →When should I change the engine oil?
2016
Change the engine oil when CHANGE ENGINE OIL SOON appears, within the next 1 000 km (600 mi), and at least once a year.
Reset the oil life system after every oil change; if it was reset accidentally, change the oil at 5 000 km (3,000 mi) since the last change.
Page 273 in the 2016 manual →How do I switch between high and low beams?
2016
Push the turn-signal lever away and release it for high beams; push it again, or pull and release it, to return to low beams.
Page 173 in the 2016 manual →What should I do if the brake system warning light stays on?
2016
If the brake system warning light comes on or stays on, the vehicle has a brake problem and needs inspection right away.
Driving with it on can lead to a crash; after carefully stopping off the road, have the vehicle towed for service.
Page 135 in the 2016 manual →What should I do if the TRANSMISSION HOT message appears?
2016
Stop the vehicle and let it idle so the transmission fluid can cool, because driving with high fluid temperature can damage the vehicle.
The message clears when the fluid temperature reaches a safe level.
Page 158 in the 2016 manual →What does the SERVICE TRANSMISSION message mean?
2016
It means there is a problem with the transmission, and the manual says to see your dealer.
