In the past twenty years hundreds of infants and young children have died after being left in vehicles, usually by accident. When turning the vehicle off, drivers of the Acadia are reminded to check the back seat if they opened the rear door before starting out. The Grand Highlander doesn’t offer a back seat reminder.
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 Grand Highlander doesn’t offer front seat center airbags.
To help make backing out of a parking space safer, the Acadia has standard Rear Cross Traffic Alert with Rear Cross Traffic Braking, systems which detect vehicles approaching from the sides and can automatically apply the brakes to prevent a collision. Only the Grand Highlander Limited/Platinum offers Parking Support Brake.
Both the Acadia and the Grand Highlander have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front and rear 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 all wheel drive, front parking sensors and driver alert monitors.
