Technology for comfort, convenience and safety
PDC Park Distance Control*
The concept The PDC assists you when you are parking. Acoustic signals and an optical display* alert you to the approach of an object from behind your vehicle. To measure the distance, there are four ultrasonic sensors in each bumper. The range of these sensors is approx. 7 ft/2 m. However, an acoustic warning first sounds for the sensors at the front and at the two rear cor- ners at approx. 24 in/60 cm, and for the center rear sensors at approx. 5 ft/1.50 m.
PDC is a parking aid that can indicate objects when they are approached
slowly, as is usually the case when parking. Avoid approaching an object at high speed, oth- erwise the physical circumstances would mean that the system warning was too late.<
Automatic activation The system starts to operate approx. one sec- ond after you shift into reverse or move the selector lever into position R with the engine running or the ignition switched on. Wait this short time before driving off.
Manual activation
Press the button, the LED lights up.
Manual deactivation Press the button again; the LED goes out.
90
Automatic deactivation After driving approx. 165 ft/50 m or at over approx. 20 mph/30 km/h, the system is switched off and the LED goes out. You can reactivate the system manually as needed.
Signal tones When nearing an object, the position is corre- spondingly indicated by an interval tone. Thus, an object detected to the left rear of the vehicle will be indicated by a signal tone from the left rear speaker, etc. As the distance between vehicle and object decreases, the intervals between the tones become shorter. If the dis- tance to the nearest object falls to below roughly 1 ft/30 cm, then a continuous tone sounds. An intermittent tone is interrupted after approx. 3 seconds: > if you remain in front of an object that was only detected by one of the corner sensors
> if you drive parallel to a wall
Malfunction The LED in the button flashes and a message appears on the Control Display. PDC is mal- functioning. Have the system checked. To prevent this problem, keep the sensors clean and free of ice or snow in order to ensure that they will continue to operate effectively. Do not spray the sensors with high-pressure clean- ers for long periods and maintain a distance of at least 4 in/10 cm to them.
PDC with visual warning* You can also have the system show distances to objects on the Control Display. Objects that are farther away are already shown there before a signal tone sounds. The setting is stored for the remote control currently in use. iDrive, for operating principle refer to page 16.
1. Press the
button.
This opens the start menu.
2. Press the controller to open the menu.
3. Turn the controller until "Settings" is
selected and press the controller.
4. Turn the controller until "Vehicle / Tires" is
selected and press the controller.
5. Change to upper field if necessary. Turn the controller until "PDC" is selected and press the controller.
6. Select "PDC display on" and press the con-
troller.
The PDC screen is activated.
The display appears on the Control Display as soon as PDC is activated.
System limits
Even with PDC, final responsibility for estimating the distance between the
vehicle and any obstructions always remains with the driver. Even when sensors are pro- vided, there is a blind spot in which objects can no longer be detected. The system is also sub- ject to the physical limits that apply to all forms of ultrasonic measurement, such as those encountered with tow bars and trailer cou- plings, or thin and wedge-shaped objects etc.
Low objects already displayed, e.g. curbs, can also disappear from the detection area of the sensors again before or after a continuous tone already sounds. Higher, protruding objects, e.g. ledges, cannot be detected. For this reason, drive with care; otherwise, there is a danger of personal injury or property damage. Loud sources of sound, inside and outside the vehicle, could drown out the PDC signal tone.<
Driving stability control systems Your BMW is equipped with an extended array of systems designed to enhance and maintain vehicle stability under extreme conditions.
ABS Antilock Brake System ABS prevents locking of the wheels during braking. Safe steering response is maintained even during full braking. Active safety is thus increased. The ABS is operational every time you start the engine. Braking safely refer to page 136.
CBC Cornering Brake Control When braking during curves or when braking during a lane change, driving stability and steer- ing response are improved further.
Electronic brake-force distribution The system controls the brake pressure in the rear wheels to ensure stable braking behavior.
Brake assistant When you apply the brakes rapidly, this system automatically produces the maximum braking force boost and thus helps to achieve the short- est possible braking distance during full brak- ing. This system exploits all of the benefits pro- vided by ABS. Do not reduce the pressure on the brake pedal for the duration of the full braking.
91
Adaptive brake assistant* In conjunction with the active cruise control with the stop-and-go function, the adaptive brake assistant ensures that the brake responds even more quickly during braking with the brake assistant.
DSC Dynamic Stability Control DSC prevents traction loss in the driving wheels when starting off and accelerating. The system also identifies unstable driving conditions, such as a loss of traction at the rear of the vehicle or sliding of the vehicle in its front wheels. In these cases, DSC helps the vehicle maintain a safe course within physical limits by reducing engine output and through braking actions in the indi- vidual wheels.
The laws of physics cannot be repealed, even with DSC. An appropriate driving style always remains the responsibility of the driver. Therefore, do not restrict the additional safety margin with a risky driving style, as other- wise there is a risk of an accident.<
Deactivating DSC
To increase vehicle stability, activate DSC again as soon as possible.
Activating DSC Press the button; the indicator lamp in the instrument cluster goes out.
For better control
The indicator lamp flashes: DSC controls the drive forces and brake forces.
The indicator lamp lights up: DSC is deactivated.
DTC Dynamic Traction Control DTC is a version of DSC in which the drive out- put is optimized for particular road conditions, e.g. unplowed snow-covered roads. The sys- tem assures the maximal drive output, but with reduced driving stability. It is therefore neces- sary to drive with appropriate caution. You may find it useful to briefly activate DTC under the following special circumstances: > When driving on snowy inclines, in slush, or on unplowed, snow-covered road surfaces > When rocking a stuck vehicle free or start-
ing off in deep snow or on loose ground
> When driving with snow chains*
Activating DTC
Press the button until the DSC indicator lamp in the instrument cluster lights up, but not longer than approx. 10 seconds. DTC Dynamic Trac- tion Control and DSC are deactivated together. Stabilizing and drive output promoting actions are no longer executed. In addition, the stability promoting intervention of the active steering* is deactivated, refer to page 99. A message appears on the Control Display. Please note any supplementary information that appears there.
92
Press the button briefly; the DTC indicator lamp in the instrument cluster lights up.
For better control
The indicator lamp flashes: DTC controls the drive forces and brake forces. The indicator lamp lights up: DTC is activated.
Deactivating DTC Press the button again; the DTC indicator lamp in the instrument cluster goes out.
xDrive on 528xi, 535xi xDrive is the 4-wheel drive system of your BMW. The combined effects of xDrive and DSC further optimize the traction and dynamic driv- ing characteristics. The 4-wheel drive system xDrive variably distributes the drive torque to the front and rear axle depending on the driving situation and prevailing road conditions.
HDC Hill Descent Control on 528xi, 535xi
The concept HDC is a system for driving downhill in steep terrain. This system reduces vehicle speed on steep downhill gradients, thus allowing you to maintain even better control of your BMW under these conditions. The vehicle moves at approximately twice walking speed without active intervention from the driver. HDC is available for activation at vehicle speeds below approx. 22 mph/35 km/h. When driving down steep hills with a speed below approx. 22 mph/35 km/h, the vehicle reduces speed automatically down to approximately double walking speed, approx. 7 mph/12 km/h, and then maintains this speed at a constant. You can use the accelerator or brakes to vary this automatically controlled speed within a range extending from approx. 3 mph/5 km/h to 15 mph/25 km/h. You can specify a target speed within the same range by using the lever of the cruise control*.
Activating HDC You can activate HDC: > with the programmable buttons on the
steering wheel, refer to page 54
> using iDrive iDrive, for operating principle refer to page 16. 1. Press the
button.
This opens the start menu.
2. Press the controller to open the menu. 3. Select "Settings" and press the controller. 4. Select "Vehicle / Tires" and press the con-
troller.
5. Change to upper field if necessary. Turn the controller until "HDC" is selected and press the controller.
6. Select "HDC on" and press the controller. HDC is shown in the instrument cluster. If the vehicle is automatically braked, a message is displayed on the Control Display for approx. 20 seconds.
Deactivating HDC When you use the programmable buttons on the steering wheel or via iDrive, the HDC display goes out. HDC is automatically deactivated in the follow- ing situations: > Above approx. 37 mph/60 km/h > After switching off the ignition
Using HDC Manual transmission: Use HDC in low gears and reverse gear.
93
Automatic transmission: You can use HDC in every drive position.

Malfunction in driving-stability control systems
The warning lamp for the brake system lights up, together with the indicator lamps for ABS, DSC and Tire Pressure Monitor or Flat Tire Monitor. A mes- sage appears on the Control Display. The driving-stability control systems have failed. Conventional braking effi- ciency remains available without limita- tions. While you may continue, you should remember to proceed cau-
tiously and drive defensively while avoiding full brake applications. The Tire Pressure Monitor or the Flat Tire Monitor is also malfunctioning. Have the system checked as soon as possible.
Display of the previously described malfunction in Canadian models.
The DSC indicator lamp lights up. A message appears on the Control Dis- play. A malfunction has occurred in the
DSC and DTC. The stabilizing actions are no
94
longer available. The vehicle remains opera- tional. Have the system checked as soon as possible.
The brake system warning lamp lights up yellow. A message appears on the Control Display. The brake assistant is defective. Have the system checked as soon as possible.
Display of the previously described malfunction in Canadian models.
Starting assistant The starting assistant enables you to start off conveniently on slopes. The handbrake is not required for this purpose. 1. Hold the vehicle with the footbrake. 2. Release the footbrake and drive off quickly.
The starting assistant holds the vehicle for approx. 2 seconds after releasing the footbrake. After releasing the footbrake, begin to drive immediately; otherwise, the starting assistant no longer holds the vehicle after approx. 1 second and your vehicle will start to roll backward.<
Dynamic Drive*
The concept Dynamic Drive minimizes body roll and opti- mizes vehicle stability during cornering and evasive maneuvers. Dynamic Drive is based on active stabilizers on the front and rear axles. Suspension compli- ance adapts to suit driving conditions, varying from performance-oriented during cornering to smooth and comfort-oriented when the vehicle is proceeding in a straight line. During vehicle operation, the system continuously runs through closed-loop control cycles lasting only fractions of a second. The system assumes operational status each time you start the engine.
Sports Wagon: self-leveling suspension
Malfunction
The warning lamp for self-leveling sus- pension lights up yellow and a message is shown on the Control Display. A mal-
function has occurred in the self-leveling sus- pension. Stop and check the vehicle. If it is con- siderably lower at the rear than at the front, and possibly also on one side – rear left compared to rear right –, go to the nearest BMW center or a workshop that works according to BMW repair procedures with correspondingly trained per- sonnel. Drive with appropriate caution in the meantime. The vehicle has reduced ground clearance and driving comfort may be notice- ably reduced. Even if the position of the vehicle is normal, go to the nearest BMW center or a workshop that works according to BMW repair procedures with correspondingly trained per- sonnel.
FTM Flat Tire Monitor*
The concept The Flat Tire Monitor detects a pressure loss in one tire by comparing the speeds of the individ- ual wheels during driving. In the event of a pressure loss, there is a change in the rolling circumference and therefore the rotation speed of the corresponding wheel. The system detects this change and reports it as a flat tire.
Functional requirement In order to assure the reliable reporting of a flat tire, the system must be initialized for the cor- rect tire inflation pressure.
The initialization must be repeated after each time the tire inflation pressure is cor-
rected and after every tire or wheel change.<
System limits The Flat Tire Monitor cannot indicate sudden severe tire damage caused by outside factors and does not detect a natural, even pressure drop in all four tires. In the following situations, the system could be delayed or malfunction: > System has not been initialized > Driving on snowy or slippery road surface > Sporty driving style: slip in the drive wheels,
high lateral acceleration
> Driving with snow chains* When you are driving with the compact wheel* the Flat Tire Monitor is unable to function.
Initializing system
The initialization finishes during driving, which can be interrupted at any time.
When driving resumes, the initialization is con- tinued automatically. Do not initialize the sys- tem when driving with snow chains* or com- pact wheel*.< iDrive, for operating principle refer to page 16. 1. Press the
button.
This opens the start menu.
