Safety is one of many good reasons to choose the 2010 ES 350; it gets a "good" rating from the Insurance Institute for Highway Safety in frontal and side protection (though it's "marginal" in the seat-based rear impact test), and NHTSA gives it five stars for front protection, five for driver side impacts, four stars for passenger side impacts, and four stars for rollover protection.
Standard safety equipment includes eight airbags, anti-lock brakes with electronic brakeforce distribution, and stability control. Rear-seat side airbags have also been added, bringing the ES 350's airbag count up to 10. All ES models additionally get the Safety Connect system, which uses cellphone technology and GPS transceivers to provide Automatic Crash Notification, Stolen Vehicle Location, emergency assistance (through an SOS button), and Roadside Assistance services. A 24-hour call center aids roadside assistance.
Adaptive Cruise Control is also available; it uses radar to keep a safe distance between the Lexus ES 350 and the vehicle ahead in the lane. Front seat belts automatically tighten and the brake assist prepares to go into action if the Lexus proprietary Pre-Collision System determines that a collision is imminent. The system will also activate the brakes without the driver if necessary, Edmunds says.
