The Acadia has a standard front seat center airbag, which deploys between the driver and front passenger, protecting them from injuries caused by striking each other in serious side impacts. The Carnival doesn’t offer front seat center airbags.
The Acadia offers all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The Carnival doesn’t offer all-wheel drive.
When descending a steep, off-road slope, the Acadia AT4’s standard Hill Descent Control allows you to creep down safely. The Carnival doesn’t offer Hill Descent Control.
The Acadia has standard OnStar®, which uses a global positioning satellite (GPS) receiver and a cellular system to get turn-by-turn driving directions, remotely unlock your doors if you lock your keys in, help track down your vehicle if it’s stolen or send emergency personnel to the scene if any airbags deploy. The Carnival doesn’t offer a GPS response system, only a navigation computer with no live response for emergencies, so if you’re involved in an accident and you’re incapacitated help may not come as quickly.
Both the Acadia and the Carnival have standard driver and passenger frontal airbags, front and rear side-impact airbags, side-impact head airbags, front seatbelt pretensioners, front wheel drive, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, blind spot warning systems, rearview cameras, rear cross-path warning, available front parking sensors and driver alert monitors.
