Starting the engine
If the engine does not start on the first attempt – if it is very hot or cold, for instance: > Press the accelerator pedal halfway
down while engaging the starter.
Cold starts at extremely low tempera- tures below approx. +57/–156 and at altitudes over 3,300 ft/1,000 m: > On the first start attempt, it may be
necessary to engage the starter for a longer period, but no longer than 20 seconds
> Press the accelerator pedal halfway
down while engaging the starter.
Extended starting attempts, char- acterized by excessively frequent
or long periods with the starter engaged, can damage the catalytic converter.<
Engine idle speed is controlled by the engine computer system. Increased speeds at start-up are normal and should decrease as the engine warms up. If engine speed does not decrease, service is required.
To prevent the battery from discharg- ing, always deactivate electrical devices that are not in use. Switch the ignition off when the vehicle is not being driven.

Parking brake
Manual transmission
Do not hold the vehicle in place on slopes by slipping or 'riding' the clutch. Use the parking brake instead. Riding the clutch leads to severe and premature clutch wear.<
If exceptional circumstances make it necessary to engage the
parking brake while the vehicle is in motion, do not pull it with excessive pressure. Keep your thumb pressed against the release button while care- fully pulling the lever up. Excessive pressure can lead to over- braking and loss of traction – fishtailing – at the rear axle. The brake lamps do not come on when the parking brake is engaged. Vehicles with manual or SMG gearbox: Engage the parking brake when parking on downhill roads, since engaging a gear may not provide adequate resis- tance to rolling, not even in first or reverse gear. Vehicles with automatic transmission: place the selector lever in P.<
To avoid corrosion and one-sided braking, apply the parking brake lightly from time to time when coasting to a standstill – at a traffic signal, for example – provided that it is safe to do so.<
6-speed transmission* When changing gear in the 5th/6th gear plane, be sure to press the gearshift lever to the right to prevent inadvert- ently shifting to a gear of the 3rd/4th gear plane.
Reverse Select only when the vehicle is station- ary. Press the shift lever to the left to overcome the resistance. As you do this, the backup lamps will light up automatically when the ignition key is in position 2.
Sequential manual gearbox SMG*
The concept The sequential manual gearbox SMG is an automated manual gearbox with which clutching and shifting is assumed by an electro-hydraulic system. The SMG is operated via the selector lever in the center console and two shift paddles on the steering wheel. It offers the following functions: > Sequential mode: manual mode > Drive mode: automatic operation > Ability to choose between two differ-
ent driving programs: Standard, Sport
> Operating safety through protection
against misshifting
> Automatic upshifts and downshifts in
the drive mode
> Automatic downshifts at minimum
engine rpm
> Kickdown function in the drive mode. > Acceleration assistant, refer to
page 72.
Selector lever positions The current selector lever position is indicated by a light-emitting diode in the center console. R: Reverse N: Neutral Position for forward driving with one- touch functions: Sequential mode +: manual upshifts —: manual downshifts D: drive mode. The SMG is ready for operation in igni- tion key position 2.
69
The gearbox is automatically placed in neutral gear if the
driver's door is opened while the engine is running and the driver does not actu- ate the pedals, the shift paddles or the selector lever. This is accompanied by an acoustic signal and the flashing gear indicator. The gear display N appears in the instrument cluster. A driving position can only be engaged when the driver's door is closed. When the vehicle is unlocked, a buzzer in the area of the transmission indicates that the system is ready for operation.<
Shiftlock When the car is at a standstill, a safety function requires you to depress the brake pedal if you want to move the selector lever from the neutral position N to a driving position.
Driving precautions
Use enough acceleration to pull away speedily when moving off on an uphill gradient. Never try to prevent the car from rolling back on an uphill gradient by depressing the accelerator pedal; always apply the handbrake. Otherwise you could overheat the SMG gearbox.<

Sequential manual gearbox SMG*
R Reverse Select only when the vehicle is station- ary.
To switch back to sequential mode: tap the selector lever again to the right toward D or change the current gear via the shift paddles or the selector lever.
Kickdown You can achieve maximum acceleration using kickdown. Depress the accelerator pedal past the increased resistance point at the full- throttle position.
N Neutral Always engage before starting the engine, refer to Starting the engine on page 66.
Sequential mode Each time the engine is started, the sequential mode is activated as soon as you move the selector lever into the for- ward driving position while the brake is depressed. The gears are shifted via the shift pad- dles or the selector lever. It is also possible to drive off in second gear, e.g. on snow-covered roads.
D Drive mode In the drive mode all forward gears are shifted automatically. To switch from sequential to drive mode: tap the selector lever to the right toward D. For rapid acceleration, e.g. during passing, depress the accelerator pedal completely: kickdown.
Shifting gears With selector lever: > To upshift, tap the selector lever
toward +
> To downshift, tap the lever toward —. With shift paddles on steering wheel: > To upshift, pull one of the shift pad-
dles
> To downshift, push the paddle. You accelerate from higher gears, e.g. during passing, by manually downshift- ing. In the following situations, the SMG in the sequential mode assists you: > The transmission will only execute
upshifts and downshifts that will result in an appropriate combination of vehicle speed and engine rpm. For
Sequential manual gearbox SMG*
instance, downshifts that would result in excessive engine speed can- not be executed
> When you brake the car to a stop, the
transmission automatically shifts down to first gear
> As speed diminishes the transmission will shift down automatically, without any action on your part, just before the vehicle slows to below each gear's minimum speed.
71
For information on jump-starting and towing the vehicle, refer to page 153.
Warning tone An acoustic signal sounds if the SMG gearbox overheats; if possible you should either stop or increase your pull- away speed so that the system can cool down.

3. Quickly press the accelerator pedal down fully: kickdown. The optimum rpm for driving off will be adjusted.
To maintain vehicle stability, always drive with the DSC acti-
vated whenever possible.<
Sport program You can choose between two driving programs: smoothly dynamic or Sport. With the Sport program, gearshifts are faster in sequential mode and the shift points are adapted in drive mode. To activate the Sport program: press the SPORT button. The LED in the but- ton lights up.
Acceleration assistant The acceleration assistant permits opti- mum racing-style acceleration on roads with good grip.
Do not use the acceleration assis- tant frequently as this could other- wise cause premature wear of the com- ponents.<
Automatic transmission with Steptronic*
73
You can drive as with a normal auto- matic transmission. In addition, you can also shift manually. When you move the selector lever from the D position to the left into the M/S range, the performance-oriented shift programs of the automatic transmission are engaged. Steptronic enters the manual selection mode and executes the desired shift whenever you tap the selector lever in the direction indicated by + or –. Whenever you want to use automatic again, just move the selector lever toward the right to position D. Under normal operating conditions, fuel consumption is lowest when driving in position D.
Selector lever positions P R N D M/S + –
Starting the engine The engine can only be started in selec- tor lever positions P – for Park – or N – for Neutral.
Range selection A catch prevents inadvertent movement of the selector lever to positions R and P. To deactivate the catch, press the button on the front of the selector lever knob, see arrow.
While the vehicle is stationary and before shifting out of Park or Neu-
tral, depress the footbrake in order to disengage the selector lever's lock mechanism – Shiftlock.<
Hold the footbrake down until starting off. The vehicle will other-
wise 'creep' when a drive position is engaged. To prevent the vehicle from starting off on its own, always move the selector lever to position P and engage the parking brake before leaving your vehicle with the engine running. Do not leave the vehicle unattended with the engine running. An unattended vehicle with a running engine repre- sents a safety hazard.<
P Park Select only when the vehicle is station- ary. Transmission locks to prevent rear wheels from turning.
R Reverse Select only when the vehicle is station- ary.
N Neutral Select only when stopping for an extended period.
D Drive – automatic shift program This position is designed for driving under all normal operating conditions. All forward gears are available.
74
Automatic transmission with Steptronic*
Kickdown In the kickdown mode, you achieve maximum acceleration and top speed in position D. Depress the accelerator pedal past the increased resistance point at the full- throttle position.
M/S manual operation and Sport program Move the selector lever from D to M/S to activate the Sport program; SD appears in the display panel. The M/S mode is recommended for perfor- mance-oriented driving. Once in the M/S mode, you can tap the selector lever to switch the automatic transmission from the Sport program to its manual mode. This mode allows you to execute upshifts manually by tapping the lever toward +, while downshifts are selected by tapping in the – direction. The dis- plays M1 through M5 appear in the dis- play panel to indicate your current gear selection.
The transmission will only execute upshifts and downshifts that will result in an appropriate combination of vehi- cle speed and engine rpm. For instance, downshifts that would result in excessive engine speed are not exe- cuted. The desired, then the actual gear, briefly appear in the instrument cluster.
To accelerate quickly in the man- ual mode for maneuvers such as
passing another vehicle, shift down manually or employ the kickdown mode.<
Shifting from M/S to the selector lever positions P, R and N is possible only by going through D.

Technology for safety and driving convenience Park Distance Control (PDC)*
86
The concept PDC assists you when you back into a parking space. Acoustic signals alert you to the momentary distance to an object behind your vehicle. The system features four ultrasonic sensors mounted in your rear bumper. The mon- itoring range for the two corner sensors extends outward roughly 2 ft/60 cm behind the bumpers, while two centrally located sensors detect objects at dis- tances of up to approx. 5 ft/1.50 m.
PDC is a parking aid that can identify objects if they are
approached slowly, as is generally the case when parking. Avoid driving towards objects rapidly; due to underly- ing physical principles, the system may otherwise alert you too late for you to take evasive steps.<
The system starts to operate automati- cally approx. one second after you shift into Reverse or move the selector lever into the R position with the ignition key in position 2.
Let this short period elapse before driving backwards.<
PDC is deactivated when you shift back out of Reverse.
You can have a signal set to con- firm that the PDC has been acti- vated. The signal then sounds when you shift into Reverse or move the selector lever into the R position.<
Acoustic signals The distance to the nearest object is indicated by a tone sounding at various intervals. As the distance between vehi- cle and object decreases, the intervals between the tones become shorter. A continuous tone indicates the pres- ence of an object less than 1 ft/30 cm away. The warning signal is canceled after approx. three seconds if the distance to the object remains constant during this time – if you are moving parallel to a wall, for instance. System malfunctions will be indicated by a continuous high-pitched tone when the system is activated the first time. Please have the problem fixed by your BMW center.
PDC does not remove the driver's personal responsibility for evaluat-
ing the distance between the vehicle and any objects. Even when sensors are involved, there is a blind spot in which objects cannot be detected. This applies especially in those cases where the system approaches the physical limits of ultrasonic measurement, as occurs with tow bars and trailer cou- plings, and in the vicinity of thin or wedge-shaped objects. Moreover, low objects that have already been detected – such as a curb edge – can disappear out of the detection range of the sensors before a continuous tone sounds. Loud sources of sound from outside or inside the vehicle could drown out the PDC signal tone.<
Keep the sensors clean and free of ice or snow in order to ensure that they will continue to operate effec- tively. Do not apply high pressure spray to the sensors for a prolonged period of time. Always maintain a distance of more than 4 in/10 cm.<
Dynamic Stability Control (DSC)
87
The vehicle will remain completely operational, however, without DSC. In the event of a fault, please consult your BMW center.
Indicator and warning lamps for Canadian models.
The concept DSC maintains vehicle stability, even in critical driving situations. The DSC is operational every time you start the engine. DSC incorporates the Dynamic Traction Control (DTC) and Cornering Brake Control (CBC) functions. For information on vehicles with all- wheel drive, refer to page 89 ff.
Indicator lamps
The indicator lamp in the instru- ment cluster goes out shortly after the ignition has been
switched on; refer to page 19. > The indicator lamp flashes: DSC is
actively controlling drive torque and braking intervention
> The indicator lamp stays lit: DSC has
been switched off with the button; DTC and DBC are operational. DTC control intervention is not indicated.
The indicator lamp and the brake warning lamp continu- ously light up in yellow: The DSC, DTC and DBC have been switched off manually or
there is a system malfunction.
Deactivating the DSC/activating the DTC Press the DSC button briefly; the indi- cator lamp comes on and stays on. DSC is deactivated; DTC is operational. In the following rare situations, it may prove useful to activate the DTC for a brief period: > When rocking the vehicle or starting off in deep snow or on loose surfaces
> When driving on snow-covered
grades, in deep snow, or on a snow- covered surface that has been packed down from being driven on
> When driving with snow chains.
88
Dynamic Stability Control (DSC)
The laws of physics cannot be repealed, even with DSC. An
appropriate driving style always remains the responsibility of the driver. We therefore urge you to avoid using the additional safety margin of the sys- tem as an excuse for taking risks. Whenever the DTC is activated, the DSC is switched off and DTC performs minor stabilizing intervention. Do not make any modifications to the DSC system. Allow only authorized technicians to perform service proce- dures on the DSC.<
Under these special circumstances traction is increased by deactivating the control systems that enhance traction under normal conditions.
Deactivating the DSC and the DTC Press the DSC button down for at least 3 seconds; the indicator lamp and the yellow brake warning lamp will remain on continuously. The systems for enhancing stability and traction are deactivated, and there is no active braking intervention or torque control.
To maintain vehicle stability, always drive with the DSC acti-
vated whenever possible.<
Reactivating the DSC Press the button again briefly; the indi- cator lamp or the indicator lamps will go out. DTC is deactivated.

If the indicator lamp fails to go out when you press the DSC button, this indicates a malfunction in the DSC and ADB-X systems; the system is deactivated, and the stability enhance- ment functions are no longer avail- able.<
To deactivate DSC Press the DSC button; the indicator lamp comes on and stays on. DSC is now off, and ADB-X reverts to its maximum torque-transfer mode. In the following exceptional circum- stances, it may be effective to deacti- vate the DSC for a short period: > When rocking the vehicle or starting off in deep snow or on loose surfaces
> When driving with snow chains.
To maintain vehicle stability, always drive with the DSC acti-
vated whenever possible.<

Allow only authorized technicians to perform service proce- dures on the DSC.<
Hill Descent Control (HDC)*
The concept By reducing the vehicle's speed on steep downhill stretches, HDC main- tains predictable vehicle handling response to provide you with control of your BMW during extreme descents. The vehicle slows to a pace just slightly faster than walking speed. HDC is available for activation at vehi- cle speeds below approx. 22 mph / 35 km/h. When driving down steep hills, the vehicle reduces speed auto- matically down to about double walking speed – approx. 7.5 mph / 12 km/h – and then maintains this speed at a con- stant. You can use the accelerator or brakes to vary this speed within a range from approx. 3 mph / 5 km/h to approx. 15 mph / 25 km/h. In conjunction with the multifunction steering wheel, you can use the +/– button to set the cruise control to a tar- get speed in the range from approx. 3 mph / 5 km/h to approx. 15 mph / 25 km/h. HDC is automatically deactivated once vehicle speed again exceeds approx. 37 mph / 60 km/h.
To activate the system Press the HDC button; the green indi- cator lamp integrated within the button comes on. The indicator lamp flashes whenever the system is actively intervening to control your speed with automatic brake applications.
To deactivate the system Press the button again, the indicator lamp goes out. HDC is automatically deactivated once the vehicle accelerates to more than 37 mph / 60 km/h, as well as whenever you switch off the ignition.
91
To use HDC Vehicles with manual transmission: You should always ensure that either reverse or first gear is engaged before using HDC, as the engine's braking effect is most pronounced in these gears, and only reduced engine braking is available in higher gears. Vehicles with automatic transmission: HDC is available for use in all ranges.
System malfunctions Are signaled by the indicator lamp, which responds to problems by going out while HDC is in operation or by fail- ing to come on when you activate the system: HDC has been temporarily deactivated as a result of high brake temperatures.
If the DSC indicator lamp comes on at the same time: Malfunction in HDC and DSC
system. Refer the problem to your BMW center.
92 Flat Tire Monitor*
The concept As you drive, the Flat Tire Monitor keeps track of pressure levels in all four tires. The system alerts you whenever the inflation pressure of a tire falls sig- nificantly below the pressure of another tire. The system actually detects pressure loss by monitoring differences in the relative speeds of the four wheels. It interprets variations outside specified limits as severe pressure loss, and then responds by generating a warning.
Functional requirements In order for the Flat Tire Monitor to learn the correct tire inflation pressure, please do the following: 1. Check the tire inflation pressures in
all tires
2. Compare them with the tire inflation pressure table on page 26 and cor- rect them, if necessary
3. Initialize the system.
System limitations
The Flat Tire Monitor cannot pro- vide you with advance warning of sudden and severe tire damage caused by external factors and does not detect the balanced and very gradual pressure loss that takes place in all four tires over an extended period of time.<
On the other hand, the following situa- tions can lead to a delayed detection of pressure loss and even to the system not functioning: > Driving on snow-covered or slippery
roads
> Performance-oriented driving: slip at the drive wheels, high levels of lateral acceleration
> When driving with snow chains, false
warnings and undetected pressure losses may occur
> When driving with a space-saver
spare tire, the Flat Tire Monitor can- not function.
Initializing the system
Each time you correct the pres- sure in a tire, or change a wheel or tire, reinitialize the system immediately afterwards. This requires a bit of driv- ing.<
1. Before driving off, start the engine
but do not start driving
2. Press the button as long as you need
to until the yellow indicator lamp in the instrument cluster lights up for a few seconds
3. Drive off. It takes a few minutes before the Flat Tire Monitor can detect a flat tire and issue a warning.
Flat Tire Monitor*
When driving with snow chains or a space-saver spare tire, do not
initialize the system.<
Flat tire
The indicator lamp in the instru- ment cluster lights up red. This visual alert is accompanied by
an acoustic warning signal. 1. Carefully reduce speed and come to
a stop. Avoid sudden braking and steering maneuvers
2. Determine which wheel is damaged
If this cannot be determined, con- tact your BMW center.<
Because the sides of Run Flat tires are reinforced, a drop in infla-
tion pressure usually cannot be detected from the outside, refer to Run Flat tires, page 150.<
2. To continue driving, follow the
instructions under Driving with a damaged tire on page 151.
System malfunction
The indicator lamp in the instru- ment cluster lights up yellow. The Flat Tire Monitor is malfunc- tioning or out of order. Please refer the problem to your BMW center.
Brake force display
93
The brake force display indicates to the driver of the vehicle behind you how hard you are braking your vehicle. The display has two levels: > Normal braking: the brake lamps
among the rear lamps and the center brake lamp light up
> Hard braking or use of ABS: the tail lamps light up with the same bright- ness as the brake lamps and thereby intensify the visual effect of the brake lamps.
3. Replace the damaged wheel, refer to
Changing a wheel on page 147.
After replacing the damaged tire, initial- ize the system. Vehicles with Run Flat tires: 1. Carefully reduce your speed to under
50 mph / 80 km/h. Avoid strong braking and steering maneuvers. Do not exceed a speed of 50 mph / 80 km/h.
Lamps Parking lamps/Low beams
94
Follow me home lamps When you activate the headlamp flasher after parking the vehicle with the lamps turned off, the low-beam head- lamps will come on for a short time.
You can also have this function deactivated.<
LIGHTS ON warning When you open the driver's door after having turned the ignition key to posi- tion 0, you will hear an acoustic signal for a few seconds to remind you that the lamps have not been switched off.
Daytime driving lamps* If you desire, the light switch can be left in the second position: when the igni- tion is switched off, the external lighting is also switched off.
You can have the activation set- tings for the daytime driving lamps
programmed on your vehicle.<
Automatic headlamp control*
When the switch is set to this position, the system automati- cally activates and cancels the low beams in response to changes in ambient light – in tunnels, at dusk, etc. – and in the event of rain and snow.
The vehicle's external lights remain on constantly when you
switch on the front fog lamps after the headlamps have come on automati- cally.<
Automatic headlamp control can- not serve as a substitute for the
driver's judgement in determining when the vehicle lights should be switched on. For example, the sensors are not able to detect fog. To avoid safety risks, you should respond to these kinds of low-visibility situations by switching the headlamps on manually.<
You can have the sensitivity of your vehicle's automatic head-
lamp control adjusted.<
Parking lamps
The front, rear and side vehicle lighting is switched on. You can use the parking lamps to signal
the position of the vehicle when it is parked. For lighting on one side for parking as an additional feature, refer to page 95.
Low beams
When the ignition is switched off while the low beams are on, the headlamps go out and only the
parking lamps remain on.
