Passive safety features

that are always on active duty.

Safety features

Under the surface of the 5 Series Sedan is a comprehensive array of passive safety features. The extremely rigid body routes impact

forces around the passenger cell. In the event of a side impact, the interlocking door anchoring system offers added protection.

Not shown: A full complement of airbags – four in front, optional side-impact airbags at the rear – includes Head Protection System,

which helps cushion and protect the heads of occupants seated by the doors.

Please note: Depending upon the type of accident, none, some or all airbags may deploy.

Smart braking features designed

to give you a driving edge.

The hallmark of a BMW – the quality that sets it apart from other makes

– is the intuitive connection it forms with the driver. A BMW’s remark-

ably responsive performance infuses every mile with driving pleasure.

Just as important, it helps you brake and maneuver around potentially

dangerous traffic situations, a feature referred to as “active safety.”

Take, for example, the large ventilated anti-lock brakes. On the 535i,

535i xDrive and 550i models, the 13.7" front/13.6" rear brakes deliver

sports-car-caliber stopping.

All 5 Series Sedans enjoy the enhanced braking capabilities of BMW’s

Dynamic Stability Control (DSC) system:

1- Brake Stand-by: When you suddenly remove your foot from the

throttle, the system anticipates you’re going to stop quickly. It

pretenses the brake calipers for quicker action when you step on

the brake pedal.

2- Brake Drying: When a sensor detects that it is raining, it reacts by

periodically bringing the brake pads into contact with the rotors just

enough to eliminate the accumulated moisture and help dry them.

3- Start-off Assistant: The system helps prevent your vehicle from

rolling backwards when you’re stopped on a hill. It even holds your

car momentarily when you release the brake to start moving again.

4- Brake Fade Compensation: Brakes heat up due to continuous or

repeated braking (like when you’re descending a winding mountain

road), so the same pedal action results in less braking power. The

system senses and compensates for this by applying the brakes

with more force while using the same pedal pressure.

Not all collisions can be avoided. That’s why every BMW is designed

to help minimize the impact on you, your passengers, and those

around you.

A BMW’s protection starts with its extremely rigid body. At speeds

up to nine mph, impacts are absorbed by bumpers and compressible

crush tubes front and rear. At higher speeds, the body is designed

to deform in a predetermined pattern, routing impact energy around

the passenger cell.

The 5 Series is equipped with BMW’s Advanced Safety System.

During a crash, various sensors assess the situation and determine

the best deployment strategy for safety restraints throughout the

vehicle. The system helps provide the most effective and efficient

use of devices, such as front-impact airbags and front-door-mounted

side-impact airbags. During side-impact collisions, BMW’s award-

winning Head Protection System (HPS) helps cushion and shield

front and rear passengers’ heads. Optional rear-seat side-impact

airbags are also available.

Whenever the 5 Series is involved in a serious accident, the BMW

Assist™ system automatically transmits your vehicle’s location to a

response specialist, who then speaks with you.

Even if you cannot

respond, they coordinate the dispatch of emergency services. And

after any severe impact, a BMW’s hazard lights flash, the interior lights

come on and the doors unlock to allow emergency assistance.
