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. ABS is operational every time you start the engine. Braking safely, refer to page 140.
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.
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The laws of physics cannot be repealed, even with DSC.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 remains the responsibility of the driver.
95
Therefore, do not restrict the additional safety margin with a risky driving style, as otherwise there is a risk of an accident.<
Deactivating DSC
Press and hold the button until the indicator lamp for DSC lights up and DSC OFF appears in the instrument panel, but do not press the but- ton for longer than approx. 10 seconds. DTC Dynamic Traction Control and DSC are deacti- vated together. Stabilizing interventions are now not carried out. A message appears on the Control Display. Please note any supplementary information that appears there. To increase vehicle stability, activate DSC again as soon as possible.
Activating DSC Press the button: the indicator lamp in the instrument panel goes out.
For better control
The indicator lamp flashes: DSC is controlling the drive forces and brake forces. The indicator lamp lights up: DSC and DTC are malfunctioning.
DSC and DTC 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 in sand, 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, sand or on loose ground
> When driving with snow chains*

Deactivating DTC Press the button again: the indicator lamp in the instrument panel goes out.
xDrive 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 forces to the front and rear axle depending on the driving situation and prevailing road conditions.
Dynamic Performance Control*
The concept Dynamic Performance Control optimizes the handling characteristics of your BMW when starting off, cornering, and during evasive maneuvers. To achieve this, the system variably distributes the drive torque of the rear axle to the two rear wheels. This further increases the
The current distribution of drive forces is indi- cated by arrows pointing to all four wheels. The highlighted arrows show the drive forces currently present. The longer an arrow is, the greater the drive forces in the associated wheel. The transparent arrows indicate the maximum value the drive forces over the last 10 seconds.
Malfunction Malfunctions are displayed via Check Control, refer to page 82.
HDC Hill Descent Control
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 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 walking
97
speed, approx. 5 mph/8 km/h, and then main- tains this speed at a constant. Only use HDC in transmission positions D or R.
Increasing or reducing speed You can use the accelerator or brakes to vary this automatically controlled speed within a range extending from approx. 4 mph/6 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. With downhill grade over 10Ξ you can reduce the speed to approx. 3 mph/4 km/h. Pull the lever of the cruise control beyond the resis- tance point, arrow 3.
The LED flashes when the brakes are applied automatically.
Deactivating HDC Press the button again. The LED and the HDC display go out. HDC is automatically deactivated at speeds over approx. 37 mph/60 km/h.

Chassis and suspension tuning You can choose between two types of chassis and suspension tuning. > Normal:
The comfortable basic setting offers opti- mum comfort when traveling.
> Sport:
1. Hold the vehicle with the brake pedal. 2. Release the brake pedal and immediately
drive off quickly.
The drive-off assistant holds the vehicle for approx. 2 seconds after releasing the brake pedal. Depending on the load, the vehicle may also roll back slightly during this time. After releasing the brake pedal, immediately start quickly, otherwise the drive-off assistant no longer holds the vehicle after approx. 2 seconds and it begins to roll back.<
The sporty basic setting offers increased driving agility.
Self-leveling suspension*
Selecting chassis and suspension tuning
Press the button. The system switches between the two chassis and suspension tuning settings. > Sport:
The LED in the button lights up and SPORT is displayed in the instrument panel.
> Normal:
The LED in the button goes out.
The selection of the chassis and suspension tuning setting is stored for the remote control currently in use.
Drive-off assistant The drive-off assistant enables you to start off conveniently on slopes. The parking brake is not required for this purpose.
The concept The self-leveling suspension on the rear axle assures a continuous ground clearance. To do so, the height of the vehicle is measured by sensors at both rear wheels. If the actual height deviates from the defined height, e.g. due to loading of the vehicle, then this difference is compensated for very quickly. In addition, spring motions resulting from cor- nering or irregularities in the road surface are reduced to a minimum. The system functions automatically.
Malfunctions Malfunctions are displayed via Check Control, refer to page 82.
FTM Flat Tire Monitor*
The concept The system does not measure the actual infla- tion pressure in the tires. The system detects a pressure loss in a tire by comparing the rotational speeds of the individ- ual wheels while moving. In the event of a pressure loss, the diameter and therefore the rotational speed of the corre- sponding wheel change. This is detected and reported as a flat tire.
99
Function requirements The system must have been initialized while the tire inflation pressure was correct; otherwise, reliable signaling of a flat tire is not ensured. Initialize the system after every correction of the tire inflation pressure and after every tire or wheel change.
System limits
Sudden serious tire damage caused by external influences cannot be indicated in
advance.< A natural, even pressure loss in all four tires cannot be detected. Therefore, check the tire inflation pressure regularly. 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.
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" 3. "Flat Tire Monitor"
The status is displayed.
100
Initialization The initialization process adopts the set infla- tion tire pressures as reference values for the detection of a flat tire. Initialization is started by confirming the inflation pressures. Do not initialize the system when driving with snow chains* or with the compact wheel*. 1. "Vehicle Info" 2. "Vehicle status" 3. "Reset"
4. Start the engine – do not drive away. 5. Start the initialization using "Reset". 6. Start to drive.
The initialization finishes during driving, which can be interrupted at any time.
When driving resumes, the initialization is con- tinued automatically.<
Indication of a flat tire
The warning lamp lights up red. A message appears on the Control Dis- play. In addition, an acoustic signal
sounds. There is a flat tire or a major loss in tire inflation pressure.
Actions in the event of a flat tire
Run-flat tires You can continue driving with a damaged tire at speeds up to 50 mph/80 km/h.
If the vehicle is not equipped with run-flat tires as provided at the factory, refer to page 249, do not continue driving. Continuing to drive with a flat tire could cause severe acci- dents.<
If you have deactivated DSC, it will be activated automatically. When driving with a damaged tire: 1. Avoid sudden braking and steering maneu-
vers.
2. Do not exceed a speed of 50 mph/80 km/h. If the defective tire continues to lose pres- sure, its position will be indicated to you on the Control Display.
3. 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.<
Possible driving distance with complete loss of tire inflation pressure. > 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 speeds of 50 mph/80 km/h or else you
run the risk of causing an accident. A loss of tire inflation pressure results in a change in the handling characteristics, e.g. reduced lane stability during braking, a longer braking distance and altered self-steering prop- erties.<
Vibrations or loud noises while driving can indicate complete failure of the tire.
Reduce your speed and stop; otherwise, pieces of the tire could come loose and cause an acci- dent. Do not continue driving, and contact your BMW Sports Activity Vehicle Center.<
Tire Pressure Monitor TPM*
The concept Monitoring of 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.
Function requirements The system must have been reset while the inflation pressure was correct; otherwise, reli- able signaling of a flat tire is not ensured. Always use wheels with TPM electronics to ensure that the system will operate properly.
Reset the system again after each correc- tion of the tire inflation pressure and after
every tire or wheel change.<
System limits
Sudden serious tire damage caused by external influences cannot be indicated in
advance.< The system does not operate correctly if it has not been reset. For example, a flat tire may be indicated despite correct tire inflation pres- sures. The system is inactive and cannot indicate a flat tire: > If a wheel without TPM electronics is
mounted, e.g. a compact wheel*
> If the TPM is disturbed by other systems or
devices with the same radio frequency
Status display The current status of the Tire Pressure Monitor TPM can be displayed on the Control Display, e.g. whether or not the TPM is active. 1. "Vehicle Info" 2. "Vehicle status"
101
Resetting system Reset the system again after each correction 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*. 1. "Vehicle Info" 2. "Vehicle status" 3. "Reset TPM"
4. Start the engine – do not drive away. 5. Start the initialization using "Reset TPM". 6. Start to drive.

Explanation according to the NHTSA/ FMVSS 138 Tire Pressure Monitoring Systems Each tire, including the spare (if provided), should be checked monthly when cold and inflated to the inflation pressure recommended by the vehicle manufacturer on the vehicle plac- ard or tire inflation pressure label. (If your vehi- cle has tires of a different size than the size indi- cated on the vehicle placard or tire inflation 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 system (TPMS) that illuminates a low tire pres- sure telltale when one or more of your tires is significantly underinflated. Accordingly, when the low tire pressure telltale illuminates, you should stop and check your tires as soon as
103
possible, and inflate them to the proper pres- sure. Driving on a significantly underinflated tire causes the tire to overheat and can lead to tire failure. Underinflation also reduces fuel effi- ciency 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 underinflation has not reached the level to trigger illumination of the TPMS low tire pressure telltale. Your vehicle has also been equipped with a TPMS malfunction indicator to indicate when the system is not operating properly. The TPMS malfunction indicator is combined with the low tire pressure telltale. When the system detects a malfunction, the telltale will flash for approximately one minute and then remain con- tinuously illuminated. This sequence will con- tinue upon subsequent vehicle startups as long as the malfunction exists. When the malfunc- tion 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
