Never install a rearward-facing child- restraint system in the front passenger seat of this vehicle if the passenger's airbag is not deactivated. If you do so, the child could be severely injured when the airbag is trig- gered.Your vehicle is equipped with an airbag supplemental restraint system for the front pas- senger. Because the backrest on any rearward- facing child-restraint system – of the kind designed for infants under 1 year and 20 Ibs./ 9 kg – would be within the airbag's deployment range, you should never mount such a system in the front passenger seat, since the impact of the airbag against the child restraint's backrest could lead to serious or fatal injuries.< More information on automatic deactivation of the front passenger airbags, refer to page 83.
Backrest width adjustment
The backrest width adjustment of the passenger seat must be opened com-
pletely. After the child's seat is installed, mem- ory positions must not be requested and the active backrest width adjustment must be deactivated, otherwise there is the risk of injury.<

senger seat and close the door.
Information regarding this is located near the buckle latch of each safety belt.
2. Open the backrest width adjustment com-
pletely, refer to page 39.
3. Deactivate active backrest width adjust-
ment, refer to page 40. Install child's seat.

Installing child-restraint systems Before installing any child-restraint system or child seat, read the following:
Observe the child-restraint system man- ufacturer's instructions for installation and use. Otherwise the degree of protection may be reduced. After an accident, have all parts of the child-restraint system and of the relevant vehicle safety belt system checked and replaced if necessary. Have this work done only at your BMW center or at a workshop that works according to BMW repair procedures with cor- respondingly trained personnel. < Commercially-available child-restraint systems are designed to be secured with a lap belt or with the lap belt portion of a combination lap/ shoulder belt. Improperly or inadequately installed restraint systems can increase the risk of injury to children. Always read and follow the instructions that come with the system.
Child seat security
To lock safety belt Pull the entire length of the belt from the belt retractor. Allow the reel to retract the belt somewhat and engage the buckle, then tighten the belt against the child-restraint system. The retraction mechanism is now locked.
To unlock the safety belt Release the buckle, remove the child-restraint system and allow the belt retractor to reel the belt completely in.
Child-restraint system with tether strap
If you use a child-restraint system with a tether strap, three additional tether anchorage points have been provided, refer to the arrows in the illustration. Depending on the location selected for sitting in the rear passenger area, attach the tether strap to the corresponding anchorage point to secure the child-restraint system, as shown in the illustration below.
All of the rear belt retractors and the front pas- senger safety belt can be locked for mounting and securing child-restraint systems.
48
Placement of the tether strap Outer sitting positions: Lift the head restraint and pass the tether strap
between the head restraint and the seat back. It is recommended to readjust the head restraint into the lowest possible position. Center sitting position: Pull the center armrest forward somewhat to guide the tether strap through the opening. Then reengage the center armrest.
The anchorage points for the LATCH child- restraint fixing system are located underneath the identifying symbols. Before attaching the LATCH child-restraint fix- ing system, pull the belt out of the region of the child-restraint fixing system.
Access to anchorage points on rear seat with through-loading system
Adjust the tether strap according to the child-restraint manufacturer's instruc-
tions.<
LATCH child-restraint fixing system LATCH: Lower Anchor and Tethers for CHil- dren. The rear outer sitting positions are provided with anchors for a LATCH child-restraint fixing system.
To attach the LATCH child-restraint fix- ing system, follow the operating and
safety instructions of the manufacturer.<
Access to anchorage points on rear seat with through-loading system
The illustration shows the right rear seat as an example. The anchorage points for the LATCH child- restraint fixing system are located behind the indicated protective caps. Before attaching the child-restraint fixing sys- tem, remove the LATCH protective caps and pull the belt away from the region of the child- restraint fixing system.
On journeys
If the rear is equipped with side airbags, make sure that children do not lean out of the child's seat towards the door panels. Other- wise severe injuries can be caused if the side airbags are triggered.<

3 Start engine
Starting engine
Do not run the engine in closed rooms, as otherwise the inhaling of toxic exhaust
gases can cause unconsciousness and death. The exhaust gases contain carbon monoxide, an odorless and colorless, but highly toxic gas. Never leave an unattended vehicle with the
engine running, as such a vehicle represents a potential safety hazard. To prevent the vehicle from rolling, always select neutral position or position N and apply the handbrake before leaving the vehicle with the engine running.< When starting the engine, do not press the accelerator pedal. Do not allow the engine to warm up by leaving it running while the vehicle remains stationary. Instead, begin to drive immediately at a moder- ate engine speed.
Special starting conditions Press the accelerator pedal halfway down when starting if > the engine fails to start on the first attempt,
for instance, if it is very hot or cold
> the engine is started at very low tempera- tures, below approx. 57/–156, at high altitudes, over approx. 3,300 ft/1,000 m.
Avoid frequent starting in quick succes- sion or repeated start attempts in which the engine does not start. Otherwise, the fuel is not burned or inadequately burned and there is a danger of overheating and damaging the cat- alytic converter.<
Manual transmission 1. Apply the handbrake. 2. Gearshift lever in neutral position. 3. Press the clutch pedal.
If the clutch pedal is not depressed, the engine will not start.<
4. Start the engine.
Do not end the starting procedure too early, however after approx. 20 seconds at the lat- est. Release the ignition key immediately as soon as the engine starts.

SMG Sequential manual transmission and automatic transmission Your BMW is equipped with the convenience starting feature. It is sufficient to turn the igni- tion key into position 3 for only a short time and then release it again. The system responds by automatically engaging the starter for a certain period and allowing it to run until the engine starts, after which it then disengages automati- cally.
SMG Sequential manual transmission 1. Press the brake pedal. 2. Place selector lever in position N. 3. Start the engine.
If the engine does not start, shift back to the last gear selected, refer to Instrument cluster display, and then shift into position N.<
Automatic transmission 1. Press the brake pedal. 2. Place selector lever in position P or N. 3. Start the engine.
Switching off engine
Do not remove the ignition key while the vehicle is rolling, as otherwise the steer-
ing wheel lock will immobilize the steering. When leaving the vehicle, remove the ignition key and lock the steering. When parking on a downhill incline, apply the handbrake, as other- wise the vehicle could roll away.<
Manual transmission 1. Turn the ignition key to position 1 or 0. 2. Shift into first gear or reverse.
SMG Sequential manual transmission 1. Engage a driving position. 2. Turn the ignition key to position 1 or 0. A signal sounds if the transmission is in Neutral when the engine is switched off.
52
Automatic transmission 1. Engage selector lever position P. 2. Turn the ignition key to position 1 or 0.
Handbrake The handbrake is primarily intended to prevent the vehicle from rolling while parked; it brakes the rear wheels.
Indicator lamp
The indicator lamp lights up, and an acoustic signal also sounds when start- ing off. The handbrake is applied. Indicator lamp for Canadian models.
Applying The lever locks in position automatically.
Releasing
Pull slightly upwards, press the button and lower the lever.
If it becomes necessary under special cir- cumstances to use the handbrake while
driving, it must not be pulled too sharply. In doing so, continuously press the button of the handbrake lever. Strong application of the handbrake can lead to overbraking of the rear axle and associated 'fishtailing' of the vehicle rear end. The brake lamps do not light up when the hand- brake is applied.<
To prevent corrosion and one-sided brak- ing action, occasionally apply the hand-
brake lightly when the vehicle is slowly coming to a stop if the traffic conditions are suitable.<
Manual transmission
> Automatic downshifting and prevention of incorrect shifting even in sequential opera- tion
> Acceleration assistant, refer to page 55. The SMG is operational when the ignition key is in position 2.
Selector lever positions
When shifting into 5th/6th gear, press the selector lever toward the right, otherwise
an inadvertent shift into 3rd or 4th gear could damage the engine.<
Reverse gear Select only when the vehicle is stationary. When pressing the gearshift lever to the left, overcome some resistance. The backup lamps switch on automatically when the ignition key is in position 2.
SMG Sequential manual transmission*
The concept The SMG Sequential manual transmission is an automated manual transmission in which an electrohydraulic system handles the clutching and gear changes. You operate the SMG using the selector lever in the center console and two shift paddles on the steering wheel. It offers you the following functions: > Optional manual or automatic operation:
Sequential mode or Drive mode
> You have a choice of two driving programs:
Normal or Sport, refer to Dynamic Driving Control page 54
The current selector lever position is displayed on the center console. > R: Reverse > N: Neutral > One-touch functions for Sequential mode:
+: manual upshifting –: manual downshifting
> D: Drive mode
The transmission automatically shifts into N if the driver's door is opened with the
engine running and neither the pedals, the shift paddles nor the selector lever are operated. This is indicated by an acoustic signal and the flashing display N in the instrument cluster.<
Gear display
R N 1 to 6
The currently engaged gear is displayed, pre- ceded by a D in Drive mode.53
g
Shiftlock Press the brake pedal before shifting out of N; the shift command will not be executed unless the brake is applied.
R Reverse Select only when the vehicle is stationary.
Using shift paddles on steering wheel
Sequential mode After every engine start, as soon as the selector lever is pushed to the right and the brake pedal is pressed, the Sequential mode is activated. You can shift up and down using the shifting paddles or the selector lever. You do not need to remove your foot from the accelerator to do so. It is also possible to start off in second gear, e.g. in slippery conditions.
D Drive mode In the Drive mode, all forward gears are shifted automatically. Shifting from Sequential mode to Drive mode: press selector lever to the right toward D. Kick-down: For rapid acceleration, e.g. when passing, press the accelerator pedal as far down as it will go. You achieve maximum acceleration. To switch back into the Sequential mode: press selector lever to the right again toward D or shift using the shifting paddles or the selector lever.
Start off quickly on slopes. Do not hold the vehicle on a hill by pressing the accel- erator, but apply the handbrake instead. Other- wise overheating can occur in the transmission region.<
Gear changes
Using selector lever > To upshift, pull the selector lever back. > To downshift, push the selector lever for-
ward.
54
> To upshift, pull one of the shift paddles. > To downshift, press. In the following situations, the SMG in Sequen- tial mode assists you: > Upshifts and downshifts are executed only when they will result in a plausible combina- tion of engine and vehicle speed; thus, for example, a downshift that would cause the engine to overrev will not be executed by the system.
> When the vehicle is stationary, the trans-
mission automatically downshifts into first gear.
> Shortly before dropping below a gear-
dependent minimum speed, the transmis- sion downshifts automatically even without your intervention.
Dynamic Driving Control The Dynamic Driving Control makes it possible for your BMW to react in an even more perfor- mance-oriented manner at the push of a button: > The engine responds more spontaneously
to accelerator pedal movements.
> Gearshifts are faster. > The engine speed range is used optimally in
the Drive mode. > Cruise control*:
The stored speed is reached more quickly when it is requested.

Maintaining speed, storing speed, and accelerating Press lever to resistance point 1: The speed currently being driven is maintained and stored. The display 1 in the speedometer, refer to page 59, indicates this regulated speed. Every time you press the lever, the vehicle's speed increases by roughly 1 mph/1 km/h. Press lever to resistance point for a longer time: The vehicle accelerates without pressure on the accelerator pedal. The system maintains and stores your current speed as soon as you release the lever. Press the lever beyond the resistance point: increase speed by 5 mph/10 km/h. The vehicle may accelerate beyond the regu- lated speed on steep downhill stretches where the engine's braking effect alone may not be sufficient to slow the vehicle. Speed can drop on uphill grades if the engine output is insuffi- cient.
Fill with water and – if required – with a washer antifreeze, according to manufacturer's recom- mendations.
In order to maintain the mixture ratio, mix the washer fluid before filling.<

Active cruise control*
The concept With active cruise control, you can select a desired speed which is not only automatically maintained when driving on open roadways, but also varied to maintain a selected distance set- ting as slower traffic is encountered. Active cruise control is 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 free- ways or other high-speed thoroughfares. Espe- cially on longer trips, 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 the scope of given possibilities, adjust your vehicle's speed auto- matically 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 system will reduce your vehicle's speed to the same as that of the vehicle ahead to maintain your selected distance setting between your vehicle and the vehicle ahead. There are four settings for dis- tance, which are additionally speed-dependent. Based on your selected distance setting, the system automatically decreases the throttle setting and lightly applies the brakes if neces- sary. The vehicle brake lamps will automatically illuminate to signal a following driver to take action. In addition, it may be necessary for the vehicle or the driver to downshift, depending on the kind of transmission your vehicle is equipped with, to maintain the distance setting selected. If the vehicle ahead speeds up or when the lane ahead becomes clear, your vehi- cle will accelerate to the speed you have selected by increasing the throttle setting and shifting gears automatically or by the driver as needed.

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 differ-
ently from conventional cruise control systems which you may be accustomed to, you are strongly urged to read all of the pages relating to this system before use. Pay special attention to the information contained in the Things to know about active cruise control section in this manual beginning on page 62.<
Vehicles with manual transmission You can use the system in the 2nd to 6th gear within a normal engine speed range and also change gears. Continuous operation at very high or very low engine speeds is not possible. In this case the driver is asked to shift or the system deactivates itself.
Vehicles with SMG Continuous operation at very high engine speeds is not possible in the Sequential mode. In this case the driver is asked to shift or the system deactivates itself. In the Drive mode, the SMG acts similarly to the automatic transmission in the D position.

Press the lever forward 1 at a driving speed of more than approx. 20 mph/30 km/h: The system applies and stores your current speed as a desired speed. This speed is indi- cated on the speedometer and displayed briefly in the instrument cluster. Subsequently pressing forward increases the desired speed to the next multiple of 5 mph/ 10 km/h. Each time the lever is pressed forward again, the desired speed is increased by another 5 mph/10 km/h until a maximum of 110 mph/180 km/h is reached. The speed then displayed is stored and achieved, provided that the road is clear.
If the display ACC --- mph/km/h briefly appears in the instrument cluster, it might be that conditions necessary for operation are not currently being met. To call up Check Control messages, refer to page 67.<
Desired speed, store and decrease Pull back the lever 2: The current driving speed is rounded off to the next multiple of 5 mph/10 km/h, displayed and stored. Each time the lever is pulled back again, the desired speed is decreased by another 5 mph/ 10 km/h until the minimum speed of 20 mph/ 30 km/h is reached. The speed then displayed is stored and achieved, provided that the road is clear.
Deactivate system Press the lever up or down while the system is active 3. The displays in the instrument cluster disappear. You can use the system again as required.

Things to know about active cruise control
As with conventional cruise control sys- tems, active cruise control in no way
diminishes or substitutes for the driver's own personal responsibility, alertness and aware- ness in adjusting speed, braking or otherwise controlling the vehicle. The driver should decide when to use the system on the basis of road, traffic, visibility, and weather conditions. Active cruise control is intended for use on highway-type roadways where traffic is moving relatively smoothly. Do not use this system in city driving; heavy traffic such as during rush
hour; on curvy, winding roads, slippery roads or roads with sharp curves such as highway off- ramps; during inclement weather such as snow, strong rain or fog; or when entering inter- changes, service/parking areas or toll booths. It is also important to regulate your vehicle's speed and distance setting within applicable 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.<
62
Always remember that the range and abil- ity of the system does have physical limi- tations. It will not apply the brakes or decelerate your vehicle when there is a slow-moving vehi- cle, stopped vehicle or stationary object ahead of you, as for example, at a traffic light or a parked vehicle. Also, the system does not react to oncoming traffic, pedestrians or other types of potential traffic such as a rider on horseback. It is also possible that the system may not detect smaller moving objects such as motor- cycles or bicycles. Be especially alert when encountering any of these situations as the sys- tem will neither automatically brake, nor provide a warning to you. Also, be aware that every decrease in the distance setting allows your vehicle to come closer to a vehicle in front of you and requires a heightened amount of alert- ness.< If while your vehicle is actively following a vehi- cle in front of you and the vehicle ahead speeds up or the lane ahead becomes clear, then your vehicle will accelerate to the speed you have selected. Be aware that changing to a clear, unobstructed lane will also result in your vehicle accelerating.
Be certain to deactivate the system when you pull into an exit lane for a highway off-
ramp.< Also, vehicles traveling in a staggered manner on a highway may cause a delay in the system's reaction to a vehicle in front of you or may cause the system to react to a vehicle actually in the lane next to you. Always be ready to take action or apply the brakes if necessary. Active cruise control can only decelerate the vehicle to approx. 20 mph/30 km/h. If the sys- tem reduces vehicle speed below 20 mph/ 30 km/h or if DSC/ABS is engaged while driving, the system will automatically deactivate.
Remember, the system cannot stop your vehicle. In addition, the system is deacti- vated whenever the driver applies the vehicle brakes, shifts the transmission to neutral/N, or deactivates DSC. After any deactivation, the system will no longer automatically activate the vehicle brakes, which means the driver must
intervene and resume manual braking. You should then reactivate the system only when you are fully aware of the prior speed and dis- tance settings.< Active cruise control may brake when you reduce the stored desired speed; however, the driver must constantly monitor traffic and inter- vene if necessary. When you switch off the engine or ignition, active cruise control is fully switched off, too, and any settings you have selected are can- celed.
Behavior in curves
Because of the limited range of the system, it is possible that in curves or on the peaks and val- leys of hilly roads, a vehicle ahead may be rec- ognized late, or not at all. Therefore, it is up to the driver to select a speed that is prudent in view of the curves and terrain of the roadway.
In approaching a curve, it is possible that active cruise control would react briefly to a vehicle in the adjacent lane. In addition, the system can sense if your vehicle is in a curve and may not accelerate. If your vehicle decelerates in either case, you can choose to overcome the deceler- ation by briefly pressing the accelerator pedal.
63
g
Driver interventions
Swerving vehicles
When a vehicle moves from an adjacent lane into your lane, active cruise control will not rec- ognize this vehicle until it is fully in your lane ahead of your vehicle.
Malfunction
The indicator lamp lights up and a mes- sage appears on the Control Display. The build-up of foreign matter, e.g., snow, ice, dirt, road debris etc., can lead to reduced detection performance of active cruise control. You should check the sensor under the front bumper and clean it as necessary prior to driving your vehicle. If the sensor becomes cov- ered by foreign matter or has a malfunction, it is possible that the sensor will no longer be able to detect vehicles in front of you. After the system recognizes that the sensor is no longer func- tional, a message is displayed on the Control Display and an acoustic signal is emitted. When the system does not recognize any objects, e.g. on infrequently traveled roads without a shoulder or guard rails, the system can automatically deactivate temporarily.
Anytime the driver presses down on the accelerator pedal, any automatic braking
action by the system is interrupted until the pedal is fully released. After doing this, release the accelerator and the system again controls your cruising speed and distance setting. While driving with activated system, resting your foot on the accelerator pedal will cause the system not to brake even if necessary. Be certain that floormats or other objects on the vehicle floor do not interfere with movement of the accelera- tor pedal.<
While active cruise control is capable of braking your vehicle automatically when
you approach a slower vehicle ahead, it is important to be aware that the ability of the sys- tem to apply the brakes is also limited, particu- larly if you are driving down a steep grade or when you reduce your desired speed sharply. The system cannot stop your vehicle. It uses only a portion of braking system capacity and does not utilize the full capacity of the vehicle braking system. Therefore, the system cannot decrease your speed for large differences in speed between your vehicle and the vehicle ahead. Examples: during emergency braking, when you approach a vehicle traveling at a much lower speed than your own speed such as approaching a toll booth or when a much slower vehicle cuts in front of you at close range.< Whenever active cruise control recognizes a situation that requires driver braking because the system capacity has been reached or has been exceeded, the system alerts the driver by flashing this symbol in the instru- ment cluster and sounding a signal.

Everything under control
Odometer, outside temperature display, clock
Tachometer
When the ignition is off you can briefly activate the time, outside temperature and odometer displays by pressing the knob 3 in the instru- ment cluster.
1 Outside temperature display, time, date The outside temperature and the time are dis- played as of ignition key position 1. Date retrieval: Press CHECK button on turn signal lever, refer to page 69. Time and date setting, refer to page 74. You can set the measurement unit 7 or 6 on the Control Display, refer to Measurement units on page 73.
Ice warning A signal sounds when the outside temperature falls to approx. +37.57/+36; this is accompa- nied by a message.
Please bear in mind that the ice warning does nothing to alter the fact that black ice may be present on roads at temperatures higher than +37.57/+36, e.g. on bridges and shaded roads.<
2 Odometer and trip odometer Resetting trip odometer: press the knob 3 in the instrument cluster.
The white-striped advance warning field, arrow 1, changes depending on the engine temperature. The segments disappear in sequence as the engine warms to its normal operating temperature. Avoid allowing the engine speed to rise as far as the orange warn- ing sector whenever possible. Engine speeds in the red warning field, arrow 2, must absolutely be avoided. In this range, the fuel supply is interrupted to protect the engine.
