The Toyota 4Runner has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags help prevent the driver and front passenger from sliding under their seatbelts or the main frontal airbags; this keeps them better positioned during a collision for maximum protection. Knee airbags also help keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The Wrangler doesn’t offer knee airbags.
The 4Runner has a standard Secondary Collision Brake, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The Wrangler doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.
Over 200 people are killed each year when backed over by motor vehicles. The 4Runner Limited/Platinum/Trailhunter/TRD Pro has standard Parking Support Brake that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The Wrangler doesn’t offer backup collision prevention brakes.
The 4Runner’s lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane and gently nudges the vehicle back towards its lane. The Wrangler doesn’t offer a lane departure warning system.
The 4Runner Premium/Limited/Platinum/Trailhunter/TRD Pro has a standard Panoramic View/Multi-Terrain Monitor to allow the driver to see objects all around the vehicle on a screen. The Wrangler only offers a rear monitor and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the front or sides.
The 4Runner has a standard blind spot warning system that uses sensors to alert the driver to objects in the vehicle’s blind spots where the side view mirrors don’t reveal them. A system to reveal vehicles in the Wrangler’s blind spot costs extra.
To help make backing out of a parking space safer, the 4Runner has standard Rear Cross Traffic Alert and Parking Support Brake on the Limited/Platinum/Trailhunter/TRD Pro automatically engages the brakes to help avoid a collision. Jeep charges extra for Rear Cross Path Detection on the Wrangler and the Wrangler’s Rear Cross Path Detection does not include automatic braking.
The 4Runner’s driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The Wrangler doesn’t offer a driver alert monitor.
Both the 4Runner and the Wrangler have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front and rear seatbelt pretensioners, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, rearview cameras and available four-wheel drive.
