Technology for driving comfort and safety
Park Distance Control PDC*
The concept The PDC assists you with maneuvering in tight parking spaces. Acoustic signals and a visual indicator warn you of the presence of an object behind your vehicle. To measure the distance, there are four ultrasonic sensors in either bumper. These sensors have a range of approx. 6.5 ft/ 2 m. However, an acoustic warning does not sound until an object is approx. 2 ft/60 cm from the corner sensors, or approx. 5 ft/1.50 m from the center sensors.
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, physical circumstances may lead to the system warning being issued too late.<
Switching on automatically With the engine running or the ignition switched on, the system is activated after approx. 1 sec- ond when you engage reverse gear or move the automatic transmission selector lever to position R. Wait this short period before driving.
Switching off automatically After approx. 55 yd/50 m of driving or above approx. 20 mph/approx. 30 km/h, the system switches off and the LED goes out.
Signal tones When nearing an object, its position is indicated correspondingly by an interval tone. As the dis- tance between vehicle and object decreases, the intervals between the tones become shorter. If the distance to the nearest object falls to below roughly 1 ft/30 cm, then a contin- uous tone sounds. An interval tone is interrupted after approx. 3 seconds
> If you remain in front of an object that has been detected by only one of the corner sensors
> If you are driving parallel to a wall.
Malfunction
The indicator lamp in the instrument cluster comes on. PDC is malfunc- tioning. A message appears on the
Control Display. Have the system checked. To avoid this problem, keep the sensors clean and free of ice or snow in order to ensure that they will continue to operate effectively. When using a high-pressure cleaner, do not spray the sensors for extended periods of time and only from a distance of at least 1 ft/30 cm.
PDC with visual warning The approach of the vehicle to an object is shown on the Control Display. Objects that are farther away are displayed on the Control Dis- play before a signal tone sounds. The display appears on the Control Display as soon as PDC is activated.
System limitations
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 trailer towbars and hitches, thin or wedge-shaped objects, etc. Low objects that have already been displayed, e.g. curbs, can disappear again from the detection area of the sensors before or after a continuous tone sounds. Higher, protruding objects, e.g. ledges, cannot be detected. Therefore, always drive cautiously; otherwise, there is a risk of personal injury or property damage. Loud sound sources outside or inside the car
81
can drown out the PDC signal. Therefore, always drive cautiously; otherwise, there is a risk of personal injury or property damage.<
Driving stability control systems Your BMW has a number of systems that help to maintain the vehicle's stability even in adverse driving conditions.
Antilock Brake System ABS 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 118.
Electronic brake-force distribution EBV The system controls the brake pressure in the rear wheels to ensure stable braking behavior.
Dynamic Brake Control DBC 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 for the duration of the full braking application.
Dynamic Stability Control DSC DSC prevents the driving wheels from losing traction when you pull away from rest or accel- erate. The system also recognizes unstable driving conditions, for example if the rear of the car is about to swerve or if momentum is acting at an angle past the front wheels. In these cases, DSC helps the vehicle maintain a safe course within physical limits by reducing engine output and through braking actions at the indi- vidual wheels.
82
The laws of physics cannot be repealed, even with DSC. An appropriate driving style always remains the responsibility of the driver. Therefore, do not reduce the additional safety margin again by taking risks, as this could result in an accident.<
Deactivating DSC
Press the button for at least 3 seconds; the indi- cator lamps for DSC in the instrument cluster light up. Dynamic Traction Control DTC and DSC have been simultaneously deactivated. Stabilizing and drive-output promoting actions are no longer executed. In the same way as with a differential interlock*, even if DSC is deactivated, brake actions are still performed to enhance drive output if the drive wheels experience a significant loss of traction. To increase vehicle stability, activate DSC again as soon as possible.
Activating DSC Press the button again; the indicator lamps in the instrument cluster go out.
For better control
If the indicator lamp flashes: DSC is regulating the drive and brak- ing forces. If the indicator lamps are on: DSC is deactivated.
Dynamic Traction Control DTC 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 uphill on snow-covered roads,
in slush or on unplowed, snow-covered roads
> 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; the indicator lamps for DTC in the instrument cluster come on.
For better control
If the indicator lamp flashes: DTC is regulating the drive and brak- ing forces. If the indicator lamps are on: DTC has been activated.
Deactivating DTC Press the button again; the DTC indicator lamps in the instrument cluster go out.
xDrive* xDrive is your BMW's four-wheel-drive system. The combined efforts of xDrive and DSC help to further optimize traction and driving dynamics. The xDrive four-wheel-drive system distributes driving power variably to the front and rear axles
depending on the driving situation and road conditions.
Hill Descent Control HDC* HDC is a downhill driving assistant that controls your speed on steep downhill gradients and makes it even easier to control your BMW's handling under these conditions. The vehicle then moves slightly faster than double walking speed without the driver needing to intervene. HDC can be activated as long as you are driving under approx. 20 mph or 35 km/h. When driving downhill at a speed of under approx. 20 mph or 35 km/h, the vehicle's speed is automatically reduced to slightly more than double walking speed and maintained.
Increasing or decreasing speed By accelerating or braking you can change this speed within a range from approx. 3 to 15 mph, approx. 5 to 25 km/h. You can specify a target speed within the same range using the cruise control* lever on the steering column.
1 To increase speed 2 To decrease speed
83
Activating HDC
Press the button; the LED lights up. When the vehicle is being braked automatically, the LED flashes.
Deactivating HDC Press the button again; the LED goes out. HDC is automatically deactivated at speeds greater than approx. 35 mph/60 km/h.
Using HDC In cars with manual transmission: Use HDC in lower gears and in reverse gear. With automatic transmission: You can use HDC in any drive position.
Displays in the instrument cluster*
1 Display for target speed 2 HDC display
Malfunction The HDC display disappears during HDC oper- ation, or does not appear: HDC is temporarily unavailable due to exces- sive brake temperature, or DSC has failed.
84
Drive-off assistant The drive-off assistant enables you to drive off smoothly on uphill gradients. It is not necessary to use the parking brake for this. 1. Hold the car in place by depressing the
brake.
2. Release the brake and drive off without
delay.
The drive-off assistant holds the car in place for approx. 2 seconds after the
brake is released. Drive off without delay after releasing the brake. Otherwise, the drive-off assistant will no longer hold the car in place after approx. 2 seconds and the car will start to roll backwards.<
Flat Tire Monitor FTM*
The concept The Flat Tire Monitor detects pressure loss in a tire by comparing the rotating speeds of the individual tires while moving. In the event of pressure loss, the rolling circum- ference changes and, thus, the rotating speed of the affected wheel. 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 system must be reinitialized each time a tire inflation pressure has been cor-
rected or a wheel or tire has been changed.<
System limitations
The Flat Tire Monitor is unable to warn the driver of sudden, severe tire damage
caused by external factors, nor can it identify the gradual loss of pressure that will inevitably occur in all four tires over a lengthy period of time.< In the following situations, the system could be delayed or malfunction:
> System has not been initialized > Driving on snowy or slippery road surface > Performance-oriented style of driving: slip in the drive wheels, high lateral acceleration
> Snow chains are attached
Initializing the system
The initialization is completed during driv- ing, which can be interrupted at any time. When driving resumes, the initialization is con- tinued automatically. Do not initialize the system while snow chains are attached.< 1. "Vehicle Info" 2. "Vehicle status" 3. "Reset"
4. Start the engine – do not drive away. 5. Start the initialization using "Reset". 6. Start driving. The initialization is completed during the trip. "Status: Flat Tire Monitor active" is displayed again on the Control Display.
Indication of a flat tire
The warning lamps come on in yellow and red. A message appears on the Control Display. In addition, an acoustic signal sounds. There is a flat
tire or substantial loss of tire pressure. 1. Cautiously reduce speed to below 50 mph
or 80 km/h. Avoid sudden braking and steering maneuvers. Do not exceed a speed of 50 mph or 80 km/h.
If the car is not equipped with run-flat tires, refer to page 216, the standard
equipment by design, do not continue driv- ing. Otherwise, a severe accident could result if you continue driving.<
2. At the next opportunity, check the air pres-
sure in all four tires.
3.
If all four tires are inflated to the cor- rect pressures, the Flat Tire Monitor might 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 guidelines: > With a light load:
1 to 2 persons without luggage: Approx. 155 miles/250 km
> With a medium load:
2 persons, cargo area full, or 4 persons without luggage: Approx. 90 miles/150 km
> With a full load:
4 or more persons, cargo area full: Approx. 30 miles/50 km Drive cautiously and do not exceed a speed of 50 mph or 80 km/h; otherwise,
there is a risk of an accident. 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 vibration or loud noises occur during the journey, this may be an indication that the damaged tire has finally failed. Reduce your speed and pull over as soon as possible at a suitable location. Otherwise, parts of the tire could come loose, resulting in an accident. Do not continue driving. Instead, contact your BMW center.<
Status display The current status of the Flat Tire Monitor can be displayed on the Control Display, e.g. whether or not the FTM is active. 1. "Vehicle Info" 2. "Vehicle status"
85
Status indicator on the Control Display The color of the tires represents the status of the tires and the system. TPM takes into account that tire pressures change while the vehicle is being driven. The tire pressures do not need to be corrected unless the TPM instructs you to do so by means of color indicators.
Green The tire inflation pressure corresponds to the established target value. "TPM active" appears on the Control Display.
One wheel yellow There is a flat tire or substantial loss of tire pres- sure in the indicated tire. A message appears on the Control Display.
All wheels yellow There is a flat tire or substantial loss of tire pres- sure in several tires. A message appears on the Control Display.
Gray The system cannot detect a puncture. Possible reasons for this: > TPM is being reset > Temporary malfunction caused by systems or devices using the same radio frequency
> Malfunction
Resetting the system
Each time a tire inflation pressure has been corrected or a wheel or tire has been
changed, reset the system.< 1. "Vehicle Info" 2. "Vehicle status"
3. "Flat Tire Monitor"
The status is displayed.
Tire Pressure Monitor TPM*
The concept RDC monitors the tire inflation pressure in the four mounted tires during a trip. The system notifies you if there is a significant loss of pres- sure in one or more tires.
Functional requirement In order to assure the reliable reporting of a flat tire, the system must be reset while all tire infla- tion pressures are correct. Always use wheels with TPM electronics. Oth- erwise, the system may malfunction.
Each time a tire inflation pressure has been corrected or a wheel or tire has been
changed, reset the system.<
System limitations
TPM cannot warn you in advance of sud- den severe tire damage caused by out-
side influences.< The system does not work correctly if it has not been reset; for example, a flat tire may be indi- cated even though the tire inflation pressures are correct. The system is inactive and cannot indicate a flat tire if a wheel without TPM electronics, such as a compact spare wheel, has been mounted, or if TPM is temporarily malfunctioning due to other systems or devices using the same radio fre- quency.

3. "Reset TPM"
4. Start the engine – do not drive away. 5. Start the initialization using "Reset TPM". 6. Start driving.
The tires are shown in gray and "Resetting TPM..." is displayed.
After driving a few minutes, the set inflation pressures in the tires are accepted as the target values to be monitored. The system reset is completed during your drive, and can be inter- rupted at any time. When the trip is resumed, the reset is continued automatically. On the Control Display, the tires are shown in green and "Status: TPM active" is displayed again.
If a flat tire is detected while the system is resetting and determining the inflation pressures, all tires on the Control Display are displayed in yellow. The message "Low tire!" is shown.<
Message for low tire inflation pressure The warning lamps come on in yellow and red. A message appears on the Control Display. In addition, a signal sounds. There is a flat tire or substan-
tial loss of tire pressure. 1. Cautiously reduce speed to below 50 mph/ 80 km/h. Avoid sudden braking and steer- ing maneuvers. Do not exceed a speed of 50 mph/80 km/h.
If the car is not equipped with run-flat tires, refer to page 216, the standard equipment by design, do not continue driv- ing. Otherwise, a severe accident could result after a tire puncture if you continue driving.<
2.
In the event of complete pressure loss, 0 psi/0 kPa, you can estimate the possible distance for continued driving on the basis of the following guidelines: > With a light load:
1 to 2 persons without luggage: Approx. 155 miles/250 km
> With a medium load:
2 persons, cargo area full, or 4 persons without luggage: Approx. 95 miles/150 km
> With a full load:
4 or more persons, cargo area full: Approx. 30 miles/50 km Drive cautiously 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 vibration or loud noises occur during the journey, this may be an indication that the damaged tire has finally failed. Reduce your speed and pull over as soon as possible at a suitable location. Otherwise, parts of the tire could come loose, resulting in an accident. Do not continue driving. Instead, contact your BMW center.<

The status is displayed.
Malfunction
The small warning lamp flashes in yellow and then lights up continu- ously; the large warning lamp comes on in yellow. On the Control Display,
the tires are shown in gray and a message appears. No punctures can be detected. This type of message is shown in the following situations: > If there is a malfunction
Have the system checked.
> If a wheel without TPM electronics has
been mounted
> If TPM is temporarily malfunctioning due to
other systems or devices using the same radio frequency.
Message for unsuccessful system reset
The warning lamp lights up yellow. A message appears on the Control Dis- play. The system is not reset, e.g.
after a wheel change. Check the tire inflation pressure and reset the system, refer to page 86.
Declaration according to NHTSA/ FMVSS 138
Tire Pressure Monitoring Systems Each tire should be checked monthly when cold and inflated to the inflation pressure recom- mended by the vehicle manufacturer on the vehicle placard or tire inflation pressure label. If your vehicle has tires of a different size than the size indicated on the vehicle placard or tire infla- tion pressure label, you should determine the proper tire inflation pressure for those tires. As an added safety feature, your vehicle has been equipped with a tire pressure monitoring sys- tem, TPMS, that illuminates a low tire pressure telltale when one or more of your tires are signif- icantly underinflated. Accordingly, when the low tire pressure telltale illuminates, you should stop and check your tires as soon as possible, and inflate them to the proper pressure. Driving88
on a significantly underinflated tire causes the tire to overheat and can lead to tire failure. Underinflation also reduces fuel efficiency and tire tread life, and may affect the vehicle’s han- dling and stopping ability. Please note that the TPMS is not a substitute for proper tire mainte- nance, and it is the driver’s responsibility to maintain correct tire pressure, even if underin- flation has not reached the level at which the TPMS low tire pressure telltale illuminates. 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 lit. This sequence will continue upon subsequent vehicle startups as long as the malfunction exists. When the malfunction indicator is illuminated, 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 Active steering varies the turning angle of the front wheels in relation to steering wheel move- ments. It also varies the steering force required to turn the wheels depending on the speed at which you are driving. When you are driving in the low road speed range, e.g. in a town or when parking, the steer- ing angle is increased, i.e. steering becomes very direct and less effort is required to turn the wheels. In the higher speed range, on the other hand, the steering angle is reduced as the speed increases. This improves the handling 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 82.
Malfunction
The warning lamps light up and a message is displayed on the Control Display. Active steering is malfunc- tioning or is temporarily deactivated.
At low speeds, greater steering wheel move- ments are required, whereas at higher speeds the vehicle reacts more sensitively to steering wheel movements. The stability-enhancing feature may also be deactivated. Drive cau- tiously and think well ahead.
Deactivation Active steering is deactivated to perform an ini- tialization. A message indicates that the feature is deactivated. Initialization may take several minutes. If the message does not disappear during the current trip, have the system checked.
Defect If there is a defect, a corresponding text mes- sage appears. Have the system checked.
Servotronic*
The concept The Servotronic varies the steering force required to turn the wheels relative to the vehi- cle speed. At low speeds, the steering force is strongly assisted, i.e. less force is needed for steering. As the vehicle speed increases, the steering assisting power is reduced.
Malfunction Malfunctions are displayed via Check Control, refer to page 77.
