The brakes are responsive and easy to modulate for smooth stopping power. Four-channel, four-sensor ABS helps the driver maintain steering control during panic stops. Brake Assist is designed to determine if the driver is attempting emergency braking; if the driver has not stepped hard enough on the brake pedal to activate the anti-lock brake system, Brake Assist applies maximum braking pressure until pedal pressure is released. Vehicle Stability Control (VSC) is an excellent active safety feature that helps the driver maintain control under adverse conditions by correcting loss of lateral traction during cornering. VSC integrates traction control to help limit rear wheel spin on slippery road surfaces. All of this advanced technology works as an integrated team, helping the driver control the car in those critical moments that separate a collision from a close call. The driver need only stand on the brakes and keep looking and steering in the direction he or she wants to go.

The optional dynamic cruise control systems are designed to maintain a set distance from the vehicle traveling in front. Some people like dynamic cruise, others don't. If you're not a big cruise control user, you don't need it.
