Along with anti-lock brakes, Ford's AdvanceTrac with Roll Stability Control is standard on all Mariners. Seat-mounted front side air bags with head-protecting Safety Canopy side-curtain air bags, a tire pressure monitoring system, and a rear view camera system are all standard as well. Other safety equipment includes the optional Active Park Assist system, which uses sensors on the front and rear of the vehicle, and works in conjunction with Electric Power Assist Steering, to guide the vehicle into a parking space. SYNC, for help with traffic, directions and information, is also available.
MyKey, a programmable key-system exclusive to Ford, is available on all trims. It allows parents to program the vehicle so that when a minor is driving, top speeds are limited to 80 mph, an alarm rings at speeds of 45, 55 or 65 mph, the audio system goes mute until the safety belt is buckled, and volume can be limited to 44% of maximum volume. It can also activate a persistent Belt-Minder chime and a traction control system that limits tire spin and cannot be deactivated.
Standard equipment on the base Mariner includes an auxiliary input jack, 110-volt AC outlet, air conditioning, keyless entry and a 4-speaker CD sound system. The Premier adds machined-aluminum wheels, leather seats with Alcantara inserts, roof rack, trip computer, ambient interior lighting and an upgraded sound system with CD changer and Sirius satellite radio. The Hybrid Limited features goodies such as heated seats, a power moonroof and SecuriCode entry.
