Standard equipment across the E-Class model line includes power front seats (with three-position memory), Smart Key entry, dual-zone climate control, cruise control, an integrated garage-door opener, rain-sensing intermittent wipers and ambient lighting. The COMAND screen- and controller-based system is also included, wrapping together radio, DVD/CD and a Bluetooth interface, as well as other media through a memory-card slot.
All E-Class models also include Attention Assist, a feature that studies the driver's steering patterns, alerting the driver with a coffee-cup icon and instrument-cluster message if, when traveling between 50 and 112 mph, it suspects drowsy driving.
The E-Class has several other noteworthy active-safety options. Night View Assist Plus uses infra-red light from beams mounted within the headlights to help see ahead nearly 500 feet--and see pedestrians up to 300 feet earlier than without the system, thanks to a screen built into the instrument cluster. There's also Distronic Plus, a sensor system that now includes Blind Spot Assist and Park Assist. Distronic Plus cars also have Pre-Safe, a system that can automatically apply full braking for an impending collision.
Blind Spot Assist and Lane Keeping Assist are offered together in a Lane Tracking Package, while the Driver Assistance Package brings Distronic Plus, Active Blind Spot Assist, and Active Lane Keeping Assist. Some of the desirable luxury features and conveniences are grouped together into Premium 1 and Premium 2 packages, while standalone options include a rear side airbag, Parktronic parking guidance, split folding rear seats, a heated steering wheel, a 115-volt power outlet and a rear-seat entertainment system, among many others
