The cabin has a 10.2-inch touchscreen with Apple CarPlay standard and Android Auto available from late 2016 onward. Dual-zone climate control is standard, with quad-zone on higher grades. Cruise control is standard, while adaptive cruise, automatic emergency braking, blind-spot warning and lane keep assist come on packages or higher trims. Rear vision camera and parking sensors are standard for easy daily use.
Trunk volume is 433 litres with seats up. Rear seats do not fold, so no expanded cargo figure is listed. The opening is wide for loading bags or luggage.
Maximum towing capacity is 454 kg across engines and drivetrains. Payload is around 510 kg depending on curb weight and GVWR. No heavy-duty cooling or reinforced suspension is listed for work use.
The cabin feels quiet and refined with acoustic laminated glass on the front doors plus active noise cancellation. Standard multi-way power front seats start at 14-way with leather. Higher trims add 16- or 20-way power seats with heating, ventilation and massage plus reclining rear seats that heat, cool and massage. Quad-zone climate with air ionization is available for tailored airflow.

Servicing relies on the oil-life monitor for engine oil and filter changes, with a mandatory yearly minimum. Tire rotations and basic inspections occur every 7,500 miles. Cadillac Premium Care covers select routine items when performed at a dealer.
Safety hardware is extensive from the start: multiple airbags including knees, electronic stability control, ABS and a rearview camera. Higher trims or packages add forward-collision alert, lane-keep assist, blind-spot monitoring, automatic emergency braking, night vision and adaptive cruise.
Living with the car centers on its quiet, spacious cabin and available rear-seat luxury. The mixed-material body keeps weight down for better efficiency and handling while the available magnetic ride and rear-steer options further refine daily comfort.
