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 Colorado are reminded to check the back seat if they opened the rear door before starting out. The Ridgeline doesn’t offer a back seat reminder.
The Colorado’s standard pretensioning seatbelts also sense rear collisions and remove slack from the front seatbelts to help protect the occupants from whiplash and other injuries. The Ridgeline doesn’t offer a whiplash protection system.
When descending a steep, off-road slope, the Colorado Trail Boss/Z71/ZR2’s standard Hill Descent Control allows you to creep down safely. The Ridgeline doesn’t offer Hill Descent Control.
The Colorado offers an optional Surround Vision to allow the driver to see objects all around the vehicle on a screen. The Ridgeline only offers a rear monitor and front and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the sides.
Both the Colorado and Ridgeline offer rear cross-traffic warning, but the Colorado has Rear Cross Traffic Braking (automatically applies the brakes) to better prevent a collision when backing near traffic. The Ridgeline’s Cross Traffic Monitor doesn’t automatically brake.
The Colorado 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 Ridgeline 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 Colorado and the Ridgeline have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, height adjustable front shoulder belts, plastic fuel tanks, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, rearview cameras, available all wheel drive and blind spot warning systems.
