The ES 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 TLX 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 ES offers optional Intuitive Parking Assist with Auto Braking that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The TLX doesn’t offer backup collision prevention brakes.
The ES 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 TLX’s blind spot costs extra.
To help make backing out of a parking space safer, the ES has standard Rear Cross-Traffic Alert to warn the driver of approaching traffic and automatically engage the brakes to help avoid a collision. Acura charges extra for Rear Cross Traffic Monitor on the TLX and the TLX’s Rear Cross Traffic Monitor does not include automatic braking.
Both the ES and the TLX have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee 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, crash mitigating brakes, daytime running lights, lane departure warning systems, rearview cameras, driver alert monitors and available around view monitors.
