bag cover panels, cover them or modify them in any way.
▷ Never modify either the individual compo‐ nents or the wiring in the airbag system. This also applies to steering wheel covers, the dashboard, the seats, the roof pillars and the sides of the headliner.◀
Even when all instructions are followed closely, injury from contact with the airbags cannot be ruled out in certain situations. The ignition and inflation noise may lead to short-term and, in most cases, temporary hear‐ ing impairment in sensitive individuals.
In the case of a malfunction, deactivation and after triggering of the airbags
Do not touch the individual components imme‐ diately after the system has been triggered; oth‐ erwise, there is the danger of burns. Only have the airbags checked, repaired or dis‐ mantled and the airbag generator scrapped by your service center or a workshop that has the necessary authorization for handling explosives. Non-professional attempts to service the sys‐ tem could lead to failure in an emergency or un‐ desired triggering of the airbag, either of which could result in injury.◀ Warnings and information on the airbags are also found on the sun visors. Automatic deactivation of the front passenger airbags The occupation of the seat is detected by eval‐ uating the impression on the occupied seat sur‐ face of the front passenger seat. The front and side airbags on the front passen‐ ger side are activated or deactivated accordingly by the system. The indicator lamp above the interior rearview mirror shows the current status of the front pas‐ senger airbags, deactivated or activated, refer to Front passenger airbag indicator lamp below.

Depending on the vehicle's equipment, the ar‐ rangement of the switches and indicator lamps may differ somewhat. The indicator lamp for the front passenger air‐ bags indicates the operating state of the front passenger airbags. The lamp indicates whether the airbags are ac‐ tivated or deactivated. ▷ The indicator lamp lights up when a child in a child restraint fixing system intended for the purpose is properly detected on the seat. The airbags on the front passenger side are not activated.
▷ The indicator lamp does not light up when,
for example, a correctly seated person of sufficient size is detected on the seat. The airbags on the front passenger side are ac‐ tivated.
▷ The indicator lamp does not light up when the seat is empty. However, the airbags on the front passenger side are not activated. The system generally detects children seated in a child seat, especially in the child seats that were required by NHTSA when the vehicle was manufactured. After installing a child seat, make sure that the indicator lamp for the front pas‐ senger airbags lights up. This indicates that the child seat has been detected and the front pas‐ senger airbags are not activated. Operational readiness of airbag system
In the radio ready state and beyond, refer to page 61, the warning lamp comes on briefly to indicate that the entire airbag system and the belt tensioners are operational.
Airbag system malfunction ▷ Warning lamp does not light up in the radio
ready state.
▷ Warning lamp remains permanently on.
Have the airbag system checked without delay if there is a malfunction
In the event of a malfunction in the airbag sys‐ tem, have it checked without delay; otherwise, there is the risk that the system will not function as intended even if a sufficiently severe accident occurs.◀
FTM Flat Tire Monitor* The concept The system does not measure the actual infla‐ tion pressure in the tires. It detects a pressure loss in a tire by comparing the rotational speeds of the individual 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. Functional requirements The system must have been initialized when the tire inflation pressure was correct; otherwise, reliable signaling of a flat tire is not ensured. In‐ itialize the system after each correction of the tire inflation pressure and after every tire or wheel change. System limits
Sudden tire damage Sudden serious tire damage caused by external influences cannot be indicated in ad‐ vance.◀ A natural, even pressure loss in all four tires can‐ not be detected. Therefore, check the tire infla‐ tion pressure regularly. The system could be delayed or malfunction in the following situations:

Do not continue driving without run-flat tires
If the vehicle is not equipped with run-flat tires as provided at the factory, do not continue driv‐ ing. Continuing to drive could cause severe ac‐ cidents.◀
Continued driving with a flat tire If continuing to drive 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 inflation
pressure in all four tires. If the tire inflation pressure in all four tires is correct, the Flat Tire Monitor may not have been initialized. In this case, initialize the system.
Possible driving distance with complete loss of tire inflation pressure: ▷ With a light load:
1 to 2 people without luggage: Approx. 155 miles/200 km.
▷ With a medium load:
2 persons, cargo area full, or 4 persons with‐ out luggage: Approx. 94 miles/150 km.

Approx. 30 miles/50 km.
The possible driving distance after a loss of tire inflation pressure depends on the cargo load and the driving style and conditions. When the vehicle is driven with a damaged tire, its handling characteristics change, e.g., re‐ duced lane stability during braking, a longer braking distance, and altered self-steering properties. Adjust your driving style accord‐ ingly. Avoid abrupt steering maneuvers or driv‐ ing over obstacles, e. g., curbs, potholes, etc. Because the possible driving distance depends on how the vehicle is used during the trip, the actual distance may be smaller or greater de‐ pending on the driving speed, road conditions, external temperature, cargo load, etc. Continued driving with a flat tire Drive moderately and do not exceed a
speed of 50 mph/80 km/h. A loss of tire inflation pressure results in a change in the handling characteristics, e.g., re‐ duced lane stability during braking, a longer braking distance and altered self-steering prop‐ erties.◀
Final tire failure Vibrations or loud noises while driving can indicate the final failure of the tire. Reduce speed and stop; otherwise, pieces of the tire could come loose and cause an accident. Do not con‐ tinue driving, and contact your service center.◀
Tire Pressure Monitor TPM* The concept The tire inflation pressure is measured in the four mounted tires. The system notifies you if there is a significant loss of pressure in one or more tires. Functional requirements The system must have been reset while the in‐ flation pressure was correct; otherwise, reliable signaling of a flat tire is not ensured.
Always use wheels with TPM electronics to en‐ sure that the system will operate properly. Reset the system after each correction of the tire inflation pressure and after every tire or wheel change. System limits

Declaration according to NHTSA/ FMVSS 138 Tire Pressure Monitoring Systems Each tire, including the spare (if provided) should be checked monthly when cold and in‐ flated to the inflation pressure recommended 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 inflation pressure la‐ bel, you should determine the proper tire infla‐ tion 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 under-inflated. Accordingly, when the low tire pressure telltale illuminates, you
92
Online Edition for Part no. 01 40 2 606 735 - 03 11 500
should stop and check your tires as soon as possible, and inflate them to the proper pres‐ sure. Driving on a significantly under-inflated tire causes the tire to overheat and can lead to tire failure. Under-inflation also reduces fuel effi‐ ciency and tire tread life, and may affect the ve‐ hicle's handling and stopping ability. Please note that the TPMS is not a substitute for proper tire maintenance, and it is the driver's re‐ sponsibility to maintain correct tire pressure, even if under-inflation has not reached the level to trigger illumination of the TPMS low tire pres‐ sure 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 approxi‐ mately one minute and then remain continu‐ ously illuminated. This sequence will continue upon subsequent vehicle startups as long as the malfunction exists. When the malfunction indi‐ cator 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 replace‐ ment or alternate tires or wheels on the vehicle that prevent the TPMS from functioning prop‐ erly. Always check the TPMS malfunction tell‐ tale 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.
Lane departure warning* The concept This system issues a warning at speeds above approx. 40 mph/65 km/h if the vehicle is about to leave the lane on roads with lane markings. The steering wheel begins vibrating lightly. The system does not issue a warning if the turn signal is set before leaving the lane.
Switching on/off
Press button 1 on the steering wheel. ▷ On: lane markings 2 are lit. ▷ Off: lane markings 2 go out. The system can issue warnings at speeds above approx. 40 mph/65 km/h. The state is stored for the remote control cur‐ rently in use. Display
1 The system is activated. 2 Arrows: at least one lane marking was de‐
tected and warnings can be issued.
Issuing a warning If the vehicle begins leaving the lane and a lane marking has been detected, the steering wheel begins vibrating. If the turn signal is set before the lane is changed, a warning is not issued. Canceling a warning The warning is canceled: ▷ Automatically after approx. 3 seconds. ▷ After the vehicle returns to its lane.

Personal responsibility The system cannot serve as a substitute for the driver's personal judgment of the course of the road and the traffic situation. In the event of a warning, do not jerk the steering wheel; otherwise, you may lose control over the vehicle.◀ The system may not be fully functional in the following situations: ▷ In heavy fog, rain or snowfall. ▷ In the event of worn, poorly visible, merging, diverging, or multiple lane markings such as in construction areas.
▷ When the demarcation lines are covered by
snow, ice, dirt or water.
▷ In tight curves or on narrow lanes. ▷ When the demarcation lines are covered by
objects.
▷ When driving very close to the vehicle in
front of you.
▷ When driving toward bright lights. ▷ When the windshield is fogged over, dirty or covered by a sticker, etc., in front of the in‐ terior rearview mirror.
Malfunctions Steering wheel vibration Frequent activation of the steering wheel vibra‐ tion causes the system to overheat. This causes the lane departure warning to be‐ come deactivated. Let the system cool and reactivate it by pressing the button.

Driving stability control systems Antilock Brake System ABS ABS prevents locking of the wheels during brak‐ ing. The vehicle remains steerable even during full brake applications, thus increasing active safety. ABS is operational every time you start the en‐ gine.
DSC also recognizes unstable vehicle condi‐ tions, such as fishtailing or nose-diving. Subject to physical limits, DSC helps to keep the vehicle on a steady course by reducing engine speed and by applying brakes to the individual wheels.
Adjust your driving style to the situation An appropriate driving style is always the
responsibility of the driver. The laws of physics cannot be repealed, even with DSC. Do not reduce the additional safety margin with a risky driving style, as otherwise there is a risk of an accident.◀
Deactivating DSC: DSC OFF When DSC is deactivated, driving stability is re‐ duced during acceleration and when driving in bends. To increase vehicle stability, activate DSC again as soon as possible. Deactivating DSC

DTC is activated.
xDrive xDrive is the all-wheel-drive system of your ve‐ hicle. 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 sit‐ uation and prevailing road conditions.
Dynamic Performance Control* The concept Dynamic Performance Control optimizes the handling characteristics of your vehicle when starting off, cornering, and during evasive ma‐ neuvers. To achieve this, the system variably distributes the drive torque of the rear axle to the two rear wheels. This further increases the steering pre‐ cision and tracking stability of your vehicle. Display The Control Display shows how xDrive and Dy‐ namic Performance Control are distributing the drive forces. 1. "Vehicle Info"
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 76.
Hill Descent Control HDC The concept HDC is a downhill driving assistant that auto‐ matically controls vehicle speed on steep down‐ hill gradients. The vehicle moves at approxi‐ mately walking speed without braking intervention by the driver. You can activate the Hill Descent Control at speeds below approx. 22 mph/35 km/h. When moving downhill at speeds below approx. 22 mph/35 km/h, the vehicle reduces its speed to approximately walking speed, approx. 5 mph/ 8 km/h and keeps it constant. Only use HDC in transmission positions D or R. Increasing or reducing speed The speed can be changed in the range from approx. 4 mph/6 km/h to approx. 15 mph/25 km/ h by pressing the accelerator or brake pedal lightly.

Drive-off assistant This system supports driving away on gradients. The parking brake is not required. 1. Hold the vehicle in place with the foot brake. 2. Release the foot brake and drive away with‐
out delay.
Depending on the vehicle load, the vehicle may roll back slightly.
Driving off without delay After releasing the foot brake, start driving without delay, since the drive-off assistant will not hold the vehicle in place for more than ap‐ prox. 2 seconds and the vehicle will begin rolling back.◀
Self-leveling suspension* 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, such as due to cargo in the vehicle, this difference is compensated very quickly. In ad‐ dition, spring motions resulting from cornering or irregularities in the road surface are reduced to a minimum. The system works automatically. Malfunctions Malfunctions are displayed via Check Control, refer to page 76.
Active steering* The concept The active steering actively varies the steering angle of the front wheels in relation to the steer‐ ing wheel movements. In addition, it also varies the steering force required for steering depend‐ ing on the vehicle's speed. When you are driving in the low speed range, for instance in a town or when parking, the steering angle increases, i.e., steering becomes very di‐ rect. In the higher speed range, on the other hand, the steering angle is reduced more and more. This improves the handling of your vehicle over the entire speed range. In critical situations, the system can make tar‐ geted corrections to the steering angle provided
100
Online Edition for Part no. 01 40 2 606 735 - 03 11 500
by the driver and thus stabilize the vehicle before the driver intervenes. Malfunction
The warning lamp lights up yellow and a message is shown on the Control Display. The active steering is defec‐ tive or has been temporarily deacti‐ vated. At low speeds, greater steering wheel movements are required, whereas at higher speeds, the vehicle reacts more sensitively to steering wheel movements. The stability-pro‐ moting intervention can also be deactivated. Proceed cautiously and drive defensively.
Deactivation Active steering deactivates in order to carry out an initialization. This deactivation is displayed by means of a message. The initialization can take several minutes. If the message does not disappear during the current trip, have the system checked. Defect In the event of a defect, a corresponding text message is displayed. Have the system checked.

Driving comfort Active cruise control* With active cruise control you can select a de‐ sired speed which is then automatically main‐ tained when driving on open roadways and is varied to maintain a selected distance setting to slower moving vehicles ahead. Active cruise control represents a technological advance over the familiar cruise control and is a welcome relief from the constant adjustment of speed that can accompany driving in traffic on highways or other high-speed thoroughfares. Especially on longer trips and in traffic conges‐ tion, the system can reduce fatigue and tension, while increasing your enjoyment of driving. Please use it safely and responsibly. In addition to holding a steady cruising speed, if you encounter slower vehicles ahead, active cruise control will, within limits, adjust your ve‐ hicle's speed automatically so that you can flow with the traffic without having to make constant adjustments. If, for example, while cruising at the selected speed, you begin to approach a slower vehicle ahead of you in the same lane, the sys‐ tem will reduce your vehicle's speed to the same as that of the vehicle ahead to maintain your se‐ lected distance setting. You can vary the follow‐ ing distance, which will vary with speed. Based on your selected distance setting, the system automatically decreases the throttle setting and lightly applies the brakes if necessary. In addi‐ tion, if the vehicle ahead of you slows to a com‐ plete stop, the system can follow this action within the given scope and can also accelerate from a complete stop if the vehicle ahead of you drives off again shortly thereafter. During brak‐ ing, your vehicle brake lamps will automatically illuminate to alert a following driver to take ac‐ tion. In addition, it may be necessary for your vehicle to downshift the automatic transmission to maintain the distance setting selected. As soon as the road in front of you has no moving vehicles, the system will accelerate to your de‐ sired speed. This set speed is also maintained on downhill grades, however the vehicle speed
102
can drop below the set speed when driving uphill if the engine output is not sufficient.
Personal responsibility Active cruise control cannot detect stop signs, red lights, or any object that is stopped or is blocking the road. Active cruise control is not and must not be used as a collision avoidance/ warning system. Since this active cruise control system is a new technology and operates dif‐ ferently from conventional cruise control sys‐ tems to which you may be accustomed, it is necessary that you read all of the pages relating to this system before use. Carefully read and observe the information on the system limita‐ tions, refer to page 106, to obtain a good com‐ mand of the system and its range of applica‐ tions.◀
Brake pedal feel When the system brakes and you also depress the brake pedal, a somewhat different braking feel results. Professional navigation system* If the vehicle is equipped with a Professional navigation system, the system adapts the ac‐ celeration and deceleration behavior of the ve‐ hicle to the road on which you are currently driv‐ ing. To ensure that the system has the latest infor‐ mation on the course of the road, use the most recent version of the navigation data. If the vehicle position is unknown, e.g., if you have left the region covered by the map, the navigation system ceases to influence vehicle behavior. Applications Please try the system first during sparse traffic and clear road conditions so that you can get used to the system. After you have experience and understand the system, only then use it dur‐ ing normal traffic.

As with conventional cruise control systems, ac‐ tive cruise control in no way reduces or substi‐ tutes for the driver's own personal experience, responsibility, alertness and awareness in ad‐ justing speed, braking or otherwise controlling the vehicle. The driver should decide when to use the system on the basis of road, traffic, vis‐ ibility, and weather conditions. Active cruise control is intended for use on highway-type roadways where traffic is moving relatively smoothly as well as in slow-moving traffic con‐ gestion. Do not use the system in city driving; in complex driving situations; heavy traffic such as during rush hour; on curvy, winding roads, slip‐ pery roads or roads with sharp curves such as highway off-ramps; during inclement weather such as snow, strong rain or fog; or when enter‐ ing interchanges, service/parking areas or toll booths. It is also important to regulate your ve‐ hicle's speed and distance setting within appli‐ cable legal limits. Always be ready to take action or apply the brakes if necessary, especially when the system is actively following a vehicle in front of you. Otherwise, driving conditions can result which lead to a violation of the law or elevated risk of an accident. The minimum initial activation speed is 20 mph/ 30 km/h, and the maximum speed is 110 mph/ 180 km/h. The system can also be ac‐ tivated while the vehicle is stationary, refer to page 105.

Storing the current speed Push the lever, arrow 1, or pull it briefly, arrow 2.
The system stores the current vehicle speed. It is indicated on the speedometer and briefly in the instrument panel.
Increasing desired speed Press or briefly push the lever up to or beyond the resistance point, arrow 1, until the desired speed is displayed. The displayed speed is stored and the vehicle reaches the stored speed if the road is clear. ▷ With each activation to the resistance point,
the desired speed increases by approx. 1 mph/1 km/h.
▷ With each activation beyond the resistance point, the desired speed increases by a max‐ imum of 5 mph/10 km/h.
Reducing the desired speed Pull the lever, arrow 2, until the desired speed is displayed. The functions are the same as those when in‐ creasing the desired speed.

Decrease the distance.
The selected distance is displayed in the instru‐ ment panel. Distance display
Distance 1, closest
Distance 2
Distance 3
Distance 4, furthest This distance is set when you ac‐ tivate the system.
Selecting an appropriate distance Use good judgement to select the appro‐ priate following distance given road conditions, traffic, applicable laws and State driving recom‐ mendations for safe following distance. Other‐ wise, a violation of the law or risk of an accident could result.◀
Press the lever up or down and additionally de‐ press the brake if the vehicle is stationary. The mark in the speedometer changes color and the distance indicator goes out. In addition, the system is interrupted: ▷ When the brakes are applied. ▷ When the transmission position D is disen‐
gaged.
▷ When DTC is activated or DSC is deacti‐
vated.
▷ When DSC is activated ▷ When the safety belt and the driver's door are opened while the vehicle is stationary. ▷ When the system has not detected objects for an extended period, e.g., on a road with very little traffic without road edge line mark‐ ings.
▷ The radar sensor is dirty.
Active intervention if the system is inter‐ rupted
If the system is interrupted, actively intervene by braking and, if necessary, with evasive maneu‐ vers; otherwise, there is the danger of an acci‐ dent occurring.◀
Calling up the stored desired speed and distance While driving Press button 4, refer to page 103. All of the dis‐ plays in the instrument panel lights up.
