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. 1 second after you shift into reverse gear 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. 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.
89
iDrive, for explanation of 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
90
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. 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 133.
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.
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 98. A message appears on the Control Display. Please note any supplementary information that appears there.
Press the button briefly; the DTC indicator lamp in the instrument cluster lights up.

Activating HDC You can activate HDC: > with the programmable buttons on the
steering wheel, refer to page 54
> using iDrive iDrive, for explanation of 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
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*.
92
Using HDC Manual transmission: Use HDC in low gears and reverse gear. 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 and warning lamps for ABS, DSC and Tire Pressure Control or Flat Tire Mon- itor. A message appears on the Control Display. The driving-stability control systems have failed. Conventional braking efficiency remains available without limitations. While you may con- tinue, you should remember to proceed cautiously and drive defensively while avoiding full brake applications. In addition, the Tire Pressure Control or the Flat Tire Monitor has also failed. 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 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.
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
93
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 keeps track of the infla- tion pressures in the tires as you drive. The sys- tem provides an alert whenever the inflation pressure drops significantly in relation to the pressure in another tire. In the event of a pressure loss, the rolling radius and therefore the rotation speed of the wheels change. This change is detected and is reported 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*
94
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 explanation of principle, refer to page 16. 1. Press the
button.
This opens the start menu.
2. Press the controller to open the menu.

9. Start to drive.
"resetting FTM …" is displayed.
The initialization finishes during driving.
Indication of a flat tire
The warning lamp lights up red. A mes- sage appears on the Control Display. In addition, an acoustic signal sounds. There is a flat tire or extensive inflation pressure loss. 1. Reduce speed and stop the vehicle care- fully. Avoid sudden braking and steering maneuvers. Identify damaged tire.
2.
If identification is not possible, con- tact a BMW center.<
3. Replace the damaged wheel, refer to
Changing wheels on page 239.
Run-flat tires* 1. Cautiously reduce speed to below 50 mph/ 80 km/h. Avoid severe braking and steering maneuvers and do not exceed a speed of 50 mph/80 km/h.
If the vehicle is not equipped with run- flat tires, refer to page 226, do not
continue driving. Continuing to drive with a flat tire could cause severe accidents.<
2. At the next opportunity, check the air pres-
sure in all four tires.
If the tire inflation pressure in all four tires is correct, the Flat Tire Monitor may not have been initialized. The system must then be initialized.<
In the event of complete tire pressure loss, 0 psi/0 kPa, you can estimate the possible distance for continued driving on the basis of the following guide values: > With a light load:
1 to 2 persons without luggage: approx. 155 miles/250 km
> With a medium load:
2 persons, cargo bay full, or 4 persons without luggage: approx. 94 miles/150 km
> With a full load:
4 or more persons, cargo bay full: approx. 30 miles/50 km Drive reservedly and do not exceed a speed of 50 mph/80 km/h. In the event of pressure loss, vehicle handling changes. This includes reduced tracking stability in braking, extended braking distance and altered natural steering characteristics. If unusual vibrations or loud noises occur while the vehicle is being driven, this can indicate final failure of the damaged tire. Reduce speed and stop at a suitable location as soon as possible, otherwise pieces of the tire could become detached and cause an accident. Do not con- tinue driving, but instead contact your BMW center.<
TPM Tire Pressure Monitor*
The concept TPM checks the tire inflation pressure in the four mounted tires. The system reports when the tire inflation pressure has dropped consid- erably in one or several tires.
Functional requirement In order to assure the reliable reporting of a flat tire, the system must have been reset with the correct tire inflation pressure. Always use wheels with TPM electronics, oth- erwise fault-free operation of the system is not ensured.
95
Gray The system cannot detect a flat tire. Reasons for this can be: > TPM is being reset > Temporary interference due to systems or
devices which use the same radio fre- quency
> Malfunction
Resetting system
Reset the system again after each correc- tion of the tire inflation pressure and after
every tire or wheel change.< Resetting finishes during driving, which can be interrupted at any time. When driving resumes, resetting is continued automatically. Do not reset the system when driving with a compact wheel*. iDrive, for explanation of 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 "TPM" is selected and press the controller.
6. Start the engine, but do not start driving. 7. Select "Reset" and press the controller.
Reset the system again after each correc- tion of the tire inflation pressure and after
every tire or wheel change.<
System limits
TPM cannot announce sudden serious tire damage caused by external influ-
ences.< The system does not function properly if it has not been reset, e.g. a flat tire is reported despite correct tire inflation pressures. The system is inactive and cannot display a flat tire if a wheel has been mounted without TPM electronics, e.g. a compact wheel, or if TPM is temporarily interfered with by other systems or devices which use the same radio frequency.
Status display on Control Display The tire and system status is indicated by the color of the tires. TPM takes the fact that the tire pressure changes during driving into account. A correc- tion is only required if requested by TPM with the color.
Green The tire pressure matches the learned set state. "TPM active" is displayed on the Control Dis- play.

If a flat tire is detected during resetting and applying the tire inflation pressures, all tires are shown in yellow on the Control Dis- play. The message "Tire low!" is displayed.<
Message with low tire inflation pressure
The warning lamp lights up yellow. A message appears on the Control Dis- play. In addition, an acoustic signal
sounds. There is a flat tire or extensive inflation pressure loss. 1. Reduce speed and stop the vehicle care- fully. Avoid sudden braking and steering maneuvers.
2. Check whether your vehicle is equipped
with standard tires or run-flat tires.
You will recognize run-flat tires by a circular symbol containing the letters
RSC on the side of the tire, refer to page 226.<
Standard tires 1.
If all four wheels are shown in yellow, iden- tify the damaged tire on the vehicle.
2. Replace the damaged wheel or wheels, refer to Changing wheels on page 239.
In contrast to a compact wheel, a spare wheel is equipped with the necessary TPM electronics and also monitored after mounting and after resetting the system. Have the tire replaced by a BMW center or a workshop informed on handling TPM which works according to BMW repair procedures with correspondingly trained personnel.
Run-flat tires* 1. Cautiously reduce speed to below 50 mph/ 80 km/h. Avoid severe braking and steering maneuvers and do not exceed a speed of 50 mph/80 km/h.
2.
If the vehicle is not equipped with run- flat tires, refer to page 226, do not
continue driving. Continuing to drive with a flat tire could cause severe accidents.< In the event of complete tire pressure loss, 0 psi/0 kPa, you can estimate the possible distance for continued driving on the basis of the following guide values: > With a light load:
1 to 2 persons without luggage: approx. 155 miles/250 km

97
Malfunction
The yellow warning lamp flashes and then lights up continuously. The tires are shown in gray on the Control Dis-
play and a message is displayed. No flat tire can be detected. A message like this is displayed in the following situations: > In case of a malfunction;
have the system checked.
> If a wheel is mounted without TPM elec-
tronics
> If TPM is temporarily interfered with by other systems or devices which use the same radio frequency.
Declaration according to NHTSA/ FMVSS 138 Tire Pressure Monitoring Systems Each tire, including the spare, should be checked monthly when cold and inflated to the inflation pressure recommended by the vehicle manufacturer on the vehicle placard or tire infla- tion pressure label. If your vehicle has tires of a different size than the size indicated on the vehicle placard or tire inflation pressure label, you should determine the proper tire inflation pressure for those tires. As an added safety fea- ture, your vehicle has been equipped with a tire pressure monitoring system, TPMS, that illumi- nates a low tire pressure telltale when one or more of your tires are significantly under- inflated. Accordingly, when the low tire pres- sure telltale illuminates, you should stop and check your tires as soon as possible, and inflate them to the proper pressure. Driving on a signif- icantly under-inflated tire causes the tire to overheat and can lead to tire failure. Under- inflation also reduces fuel efficiency and tire tread life, and may affect the vehicle's handling and stopping ability. Please note that the TPMS is not a substitute for proper tire maintenance, and it is the driver's responsibility to maintain correct tire pressure, even if under-inflation has not reached the level to trigger illumination of the TPMS low tire pressure telltale.
98
The TPMS malfunction indicator is combined with the low tire pressure telltale. When the sys- tem detects a malfunction, the telltale will flash for approximately one minute and then remain continuously illuminated. This sequence will continue upon subsequent vehicle startups as long as the malfunction exists. When the mal- function indicator lights up, the system may not be able to detect or signal low tire pressure as intended. TPMS malfunctions may occur for a variety of reasons, including the installation of replacement or alternate tires or wheels on the vehicle that prevent the TPMS from functioning properly. Always check the TPMS malfunction telltale after replacing one or more tires or wheels on your vehicle to ensure that the replacement or alternate tires and wheels allow the TPMS to continue to function properly.
Active steering*
The concept The active steering is a system that actively var- ies the steering angle of the front wheels in rela- tion to the steering wheel movements. When you are driving in the low road speed range, e.g. in a town or when parking, the steer- ing angle increases, i.e. the steering becomes very direct. In the higher speed range, on the other hand, the steering angle is reduced more and more. This improves the handling capability of your BMW over the entire speed range. In critical situations, the system can make tar- geted corrections to the steering angle pro- vided by the driver and thus stabilize the vehicle before the driver intervenes. This stabilizing intervention is simultaneously deactivated when DSC is switched off, refer to page 91.
Malfunction
The warning lamp lights up yellow and a message is shown on the Control Dis- play. The active steering is no longer operational. At low speeds, greater steering wheel movements are required, whereas at higher speeds, the vehicle reacts more sensi-
tively to steering wheel movements. The stabil- ity-promoting intervention can also be deacti- vated. Proceed cautiously and drive defensively. Have the system checked.
Brake force display
On the left: normal braking. On the right: heavy braking.
Airbags
The following airbags are located under the marked covers: 1 Front airbags 2 Head airbags 3 Side airbags in front and rear
Protective action
To ensure that the safety systems con- tinue to provide optimized protection,
please observe the adjustment instructions on page 45.< The front airbags help protect the driver and front passenger by responding to frontal impacts in which safety belts alone cannot pro- vide adequate restraint. When needed, the head and side airbags help provide protection in the event of side impact. The relevant side air- bag supports the side upper body area. The head air bag supports the head.
The airbags are deliberately not triggered in every impact situation, e.g. less severe acci- dents or rear-end collisions.
