Worth knowing about the 2018 Acadia
- Bulbs. The 9012 (HIR2) halogen headlamp applies to trims with halogen headlamps; Denali and HID or LED lamps differ.
- Torque. Tighten lug nuts to 140 ft-lbs in a star pattern with a torque wrench, and re-check after the first 50 miles. This figure is from the owner's manual; an impact gun will overshoot it.
- TPMS. New sensors on this car need a relearn (tool); they will not pair on their own by driving.
- Key fob. Match the FCC ID (HYQ1EA) printed on the back of your fob when buying a replacement; the same car can use two fob designs in one year. A new fob still needs programming to the car.
- Key fob. The smart key came in 3-, 4- and 5-button versions depending on remote start and power liftgate.
- Roof load. The 220 lb roof limit is the dynamic figure for driving and includes the rack itself. It is not a limit for a rooftop tent when parked; the manual gives no static figure.
- Fuel. AWD models hold 21.7 gallons.
