Transporting children safely
The right place for children
Do not leave children unattended in the vehicle, otherwise they could endanger
themselves and other persons, e.g. by opening the doors.<
Children always in the rear Accident research shows that the safest place for children is on the back seat.
Children younger than 13 years of age or with a height under 5 ft/150 cm may only be transported in the rear in child restraint sys- tems which correspond to the age, weight and height of the child. Otherwise there is an increased danger of injury in an accident.< Children 13 years of age or older must wear a safety belt as soon as a suitable child restraint system can no longer be used due to their age, size and weight. With the exception of the driver's seat, all seats in your BMW comply with the recommenda- tions of the standard SAE J1819 for the safe securing of child restraint systems in motor vehicles.
Exception for front passenger seat Should it be necessary to use a child restraint system on the front passenger
seat, the front and side airbag on the passenger side must be deactivated. Otherwise, there is an increased risk of injury for the child if the air- bags are triggered, even with a child restraint system. Your BMW center will be glad to advise you.< For more information on automatic deactivation of the front passenger airbags, refer to page 95.

Installing child restraint systems
Observe the child restraint system manu- facturer's instructions for selection,
installation and use of the child restraint sys- tems. Otherwise the degree of protection may be reduced.<
Backrest width* on front passenger seat
Before mounting a child restraint system on the front passenger seat, the backrest
width adjustment must be open completely. After mounting the child's seat, no memory position may be called up and the active back- rest width adjustment must be deactivated, otherwise the stability of the child's seat on the front passenger seat is limited.< 1. After unlocking the vehicle, place on the
front passenger seat and close the door to call up the memory position.
2. Completely open the backrest width adjust-
ment, refer to page 46.
3. Deactivate active backrest width adjust-
ment, refer to page 47. Install child's seat.

Child seat security
All rear safety belts and the safety belt for the front passenger can be locked against pulling out to secure child restraint systems.
Locking safety belt 1. Secure the child restraint system with the
belt.
2. Pull out the belt webbing completely. 3. Allow the belt webbing to be pulled in and pull taut against the child restraint system. The safety belt is locked.
Unlocking safety belt 1. Open the belt buckle. 2. Remove the child restraint system. 3. Allow the belt webbing to be pulled in com-
pletely.

Starting engine
Do not run the engine in closed rooms, 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. Before leaving the vehicle with the engine run- ning, set the selector lever to the idling or the P position and set the handbrake, otherwise the vehicle can begin to roll.< 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.
Do not press either the brake or the clutch pedal as long as you do not want to start
the engine. The engine starts immediately when you briefly press the Start/Stop button and press the brake pedal with an automatic transmission* or the clutch pedal with a manual transmission.<
Manual transmission 1. Apply the handbrake. 2. Depress the clutch pedal and select the
idling position.
3. Briefly press Start/Stop button. The system responds by automatically engag- ing the starter for a certain period and automat- ically disengaging it as soon as the engine starts.
Automatic transmission* 1. Depress brake pedal. 2. Place selector lever in position P or N. 3. Briefly press Start/Stop button. The system responds by automatically engag- ing the starter for a certain period and automat- ically disengaging it as soon as the engine starts.
SMG Sequential Manual Transmission* 1. Depress brake pedal. 2. Engage selector lever position N and make
sure that this position is also indicated in instrument cluster.
3. Briefly press Start/Stop button. The system responds by automatically engag- ing the starter for a certain period and automat- ically disengaging it as soon as the engine starts.
If the engine fails to start, depress the brake pedal and press the selector lever to the right then engage the position N. Watch the display in the instrument cluster while doing so.<
Special starting conditions Depress the accelerator pedal half way when starting the engine in the following situations: > The engine fails to start on the first attempt,
e.g. 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 starting 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 catalytic converter.<

Switching off engine
Do not remove the remote control from the ignition lock while the vehicle is roll- ing, otherwise the steering wheel lock would engage while steering. When leaving the vehicle, always take the remote control with you. When parking on a downhill incline, apply the handbrake, as otherwise the vehicle could roll away.<
Manual transmission 1. Briefly press the Start/Stop button with the
vehicle stopped.
2. Shift into first gear or reverse. 3. Apply the handbrake.
SMG Sequential Manual Transmission* 1. Apply the handbrake. 2. Engage a driving position. 3. Briefly press the Start/Stop button.
If the position N is engaged when the engine is switched off, this is pointed out visually and acoustically.
Automatic transmission* 1. Select the selector lever position P with the
vehicle stopped.
2. Briefly press the Start/Stop button.
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 a sig- nal also sounds when starting off. The handbrake is applied. Indicator lamp for Canadian models.
60
Applying The lever locks in position automatically.
Releasing
Pull slightly upwards, press the button and lower the lever.
If exceptional circumstances should make it necessary to engage the hand-
brake while the vehicle is in motion, do not pull it too strongly. In doing so, continuously press the button of the handbrake lever. Otherwise excessive pressure can lead to the rear wheels locking up and loss of traction – fishtailing – at the rear axle.<
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. The brake lamps do not light up when the hand- brake is applied.<
Manual transmission
While shifting in the 5th/6th gear lane, press the gearshift lever toward the right, otherwise accidental shifting into the 3rd or 4th gear could result in engine damage.<
Reverse gear Select only when the vehicle is stationary. When pressing the gearshift lever to the left, overcome some resistance.
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. The SMG is operated with the selector lever 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 62
> Automatic downshifting and prevention of incorrect shifting even in Sequential opera- tion
> Acceleration assistant, refer to page 63.
Selector lever positions
> R: Reverse gear > N: Neutral > One-touch functions for Sequential mode:
+: manual upshifting –: manual downshifting
> D: activate/deactivate the 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 oper- ated. This is signaled by an acoustic signal and the flashing display N in the instrument cluster; a message appears on the Control Display.<
Gear display
R N 1 to 6
The currently engaged gear is displayed, pre- ceded by a D in Drive mode.It is only possible to recognize whether the desired selector lever position is
engaged with this display.<
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.
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.
61
g
In the following situations, SMG thinks for 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.
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 accel- eration. 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.
Using shift paddles on steering wheel
> To upshift, pull one of the shift paddles. > To downshift, press.
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.

Washer fluid
Washer fluid antifreeze is flammable. Always keep it well away from sparks and open flames, and store it in tightly closed con- tainers well out of the reach of children. Always observe the instructions for use provided on the containers.<
Washer fluid reservoir
All washer jets are supplied from one reservoir. 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.<
Capacity Sedan: approx. 3.2 US quarts/3 liters, with headlamp washer system* approx. 5.3 US quarts/5 liters. Sports Wagon: approx. 5.3 US quarts/5 liters.
Cruise control*
The concept The cruise control is available for use at speeds of approx. 20 mph/30 km/h and higher. The vehicle stores and maintains the speed that you set using the lever mounted on the steering col- umn.
Do not use the cruise control under driv- ing conditions that do not permit a con-
stant speed, e.g. when driving on winding roads, in heavy traffic or in poor road conditions such as snow, rain, ice, and loose road surface.
Otherwise you could loose control of the vehi- cle and cause an accident.<

Maintaining speed, storing speed, and accelerating Press lever to resistance point, arrow 1: The speed currently being driven is maintained and stored. The display 1 in the speedometer, see below, 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. If, on a downhill grade, the engine's braking effect is not sufficient, the controlled speed can be exceeded. Speed can drop on uphill grades if the engine output is insufficient.

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.
67
g
Especially 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. You can vary the distance, which is additionally speed-dependent. Based on your selected distance setting, the system automatically decreases the throttle setting and lightly applies the brakes if necessary. The vehi- cle brake lamps will automatically illuminate to signal a following driver to take action. In addi- tion, 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 vehicle will acceler- ate to the speed you have selected by increas- ing the throttle setting and shifting gears auto- matically or by the driver as needed. Your selected speed will be held when driving down- hill, too.
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 begin- ning on page 71.<
68
Professional navigation system* If a navigation DVD is in the drive, refer to page 132, the system adjusts the accelerating and braking behavior of the vehicle to the road you are driving on.
To ensure that the system is informed of the current course of the road, always use
the latest navigation DVD if possible.< When the vehicle position is unknown, e.g. when you leave the map area, this influence of the navigation system is not available.
Brake pedal feel > When the system brakes and you also
depress the brake pedal, a somewhat differ- ent braking feeling results.
> Any noises produced during automatic
braking are normal.
Manual transmission You can shift with the cruise control activated. Shifting information is provided or the system deactivates itself if you drive at very high or very low engine speeds for a longer period.
SMG In the Sequential mode, shifting information is provided or the system deactivates itself if you drive at very high engine speeds for a longer period. In the Drive mode the SMG acts similarly to an automatic transmission in the D position.

The display 2 flashes yellow. Automatic intervention by ABS or DSC. The active cruise control intervenes by braking until you take over actively.
Heavy rain, dirt, snow or ice can restrict the detection of vehicles driving ahead. If neces- sary, clean the front radar sensor under the bumper. Exercise particular care when remov- ing snow and ice. If the sensor is not aligned properly, the active cruise control cannot be activated.
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.<
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
71

system will neither automatically brake, nor pro- vide 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.

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.
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
