Automatic climate control
Maximum cooling
Comfortable interior climate AUTO program 7 offers the ideal air distribution and air volume for almost all conditions, refer to AUTO program below. All you need to do is select an interior temperature which is comfort- able for you. The following sections inform you in detail about how to adjust the settings. Most settings are stored for the remote control currently in use, refer also to Personal Profile settings on page 26.
Adjusting air distribution manually
The air distribution can be switched on and off manually. The air is directed to the windshield, to the upper body area and to the
footwell. The automatic air distribution can be switched back on by pressing the AUTO button. The cooling function is switched on automatically and the manual air distribution setting is cleared.
Temperature
Turn to set the desired tempera- ture. The automatic climate control achieves this temperature as
quickly as possible regardless of the season, using maximum cooling or heating power if nec- essary, and then maintains it. Avoid rapid switching between different tem- perature settings. The automatic climate con- trol will not have sufficient time to adjust the set temperature. Maximum heating power can be obtained with the highest setting, regardless of the outside temperature. The system cools steadily in the lowest setting, regardless of the outside temperature.

Microfilter/activated-charcoal filter The microfilter traps dust and pollen in the incoming air. The activated-charcoal filter pro- vides additional protection by filtering gaseous pollutants from the outside air. Your BMW cen- ter replaces this combined filter during routine maintenance.
Parked car ventilation
The concept The parked car ventilation provides ventilation to the passenger compartment and lowers its temperature, if necessary. It is ready for use at any outside temperature, as of radio readiness. The parked car ventilation remains switched on for approx. 30 minutes. Two different switch-on times can be preselected. The system can also be switched on and off directly. Due to its high power consumption, it should not be switched on twice in a row without driv- ing in between to allow the battery to recharge. The air emerges from the air vents for the upper body area in the instrument panel. The air vents must therefore be open.
The parked car ventilation system is operated via iDrive.

Practical interior accessories
Integrated universal remote control*
HomeLink is a registered trademark of Johnson Controls, Inc.<
The concept The integrated universal remote control can replace as many as three hand-held transmit- ters for various remote-controlled devices, such as garage doors and gates or lighting sys- tems. The integrated universal remote control registers and stores signals from the original hand-held transmitters. The signal of an original hand-held transmitter can be programmed on one of the three mem- ory buttons 1. After this, the programmed memory button 1 will operate the system in question. The LED 2 flashes to confirm trans- mission of the signal. Should you sell your vehicle one day, be sure to delete the stored programs beforehand for your safety, refer to page 103.
To prevent possible damage or injury, before programming or using the inte-
grated universal remote control, always inspect the immediate area to make certain that no peo- ple, animals or objects are within the pivoting or travel range of the device being operated. Com- ply also with the safety instructions supplied with the original hand-held transmitter.<
Checking compatibility
If this symbol appears on the package or in the instructions supplied with the original hand-held transmitter, you can assume that the radio remote control device will be compatible with the integrated universal remote control. For additional information, please contact your BMW center or call: 1-800-355-3515. You can also obtain information on the Internet at: www.bmwusa.com or www.homelink.com.

Driving tips Driving tips
This section provides you with information useful in dealing with specific driving and operating conditions.

Things to remember when driving
Break-in period Moving parts need breaking-in time to adjust to each other. Please follow the instructions below in order to achieve the optimal service life and economy of operation for your vehicle.
Following part replacement The same break-in procedures should be observed if any of the components mentioned above have to be renewed in the course of the vehicle's operating life.
Engine and differential Always obey all official speed limits.
Up to 1,200 miles/2,000 km Drive at varying engine and road speeds but do not exceed: > Gasoline engine
4,500 rpm or 100 mph/160 km/h
> Diesel engine
3,500 rpm or 93 mph/150 km/h
Avoid full-throttle operation and use of the transmission's kickdown mode.
After driving 1,200 miles/2,000 km Engine and vehicle speeds can be gradually increased.
Tires Due to technical factors associated with their manufacture, tires do not achieve their full trac- tion potential until after an initial break-in period. Therefore, drive cautiously during the first 200 miles/300 km.
Brake system Brakes require an initial break-in period of approx. 300 miles/500 km to achieve optimized contact and wear patterns between brake pads and rotors. Drive cautiously during this break-in period.
Clutch The function of the clutch reaches its optimal level only after a distance driven of approx. 300 miles/500 km. During this break-in period, engage the clutch gently.
116
Saving fuel The fuel consumption of your vehicle depends on several factors. You can lower fuel consump- tion and the environmental impact by taking certain measures, adjusting your driving style and having the vehicle serviced regularly.
Remove any unneeded cargo Additional weight increases fuel consumption.
Remove any mounted parts after you have finished using them Remove unneeded additional mirrors, the roof rack and the rear luggage rack after use. Mounted parts affect the vehicle's aerodynam- ics and increase fuel consumption.
Close the windows and glass roof An open glass roof or window causes higher air resistance and thus increases fuel consump- tion.
Check tire inflation pressure regularly Check the tire inflation pressure at least twice a month and before embarking on a long journey, and correct it if necessary. Low tire inflation pressure causes higher rolling resistance and thus increases fuel consumption and tire wear.
Set off immediately Do not let the engine warm up while the car is still standing, but set off immediately at moder- ate engine speed. This is the fastest way for the cold engine to reach its operating temperature.
Drive defensively Avoid unnecessary acceleration and braking maneuvers. To do so, keep an adequate dis- tance between you and the vehicle in front of you. A defensive and smooth driving style keeps fuel consumption down.
Have the vehicle serviced Have the vehicle serviced regularly to achieve good economy and a long vehicle life. BMW recommends having the vehicle serviced at a BMW center. Also note the BMW service sys- tem, refer to page 223.
Avoid high engine speeds Only use first gear when setting off. In second and higher gears, accelerate without hesitation or pauses. When accelerating, shift up before reaching high engine speeds. When you reach the desired speed, shift into the highest applicable gear and drive with the engine speed as low as possible and at a con- stant speed. As a rule: driving at low engine speeds lowers fuel consumption and reduces wear.
Coasting When approaching a red light, take your foot off the accelerator and coast to a stop in the high- est applicable gear. On a downhill slope, take your foot off the accel- erator and coast in a suitable gear. The fuel supply is interrupted when coasting.
Switch off the engine during lengthy stops Switch off the engine when stopping for lengthy periods, e.g. at traffic lights, railroad crossings or in traffic congestions. You achieve fuel sav- ings even if standing time is as short as approx. 4 seconds.
Switch off functions you do not need at the moment Functions such as the air conditioner, seat heating or rear window defroster draw large amounts of power and consume additional fuel. Especially in city traffic and in stop and go driv- ing they have a considerable impact. Therefore, switch these functions off when they are not really needed.
General driving notes
Close the trunk lid/tailgate
Operate the vehicle only when the trunk lid/tailgate and rear window are closed.
Otherwise, exhaust fumes could enter the inte- rior of the vehicle.< If the vehicle must be driven with the trunk lid/ tailgate open: 1. Close all windows and the glass roof. 2. Greatly increase the air volume of the auto-
matic climate control system, refer to page 98.
Hot exhaust system
In all vehicles, extremely high tempera- tures are generated in the exhaust sys- tem. Do not remove the heat shields installed adjacent to various sections of the exhaust sys- tem, and never apply undercoating to them. When driving, standing at idle and while park- ing, take care to avoid possible contact between the hot exhaust system and any highly flammable materials such as hay, leaves, grass, etc. Such contact could lead to a fire, with the risk of serious personal injuries and property damage. Do not touch hot exhaust tail pipes. Otherwise, there is a risk of burns.<
Diesel particulate filter* The diesel particulate filter collects soot parti- cles and burns them periodically at high tem- peratures. This cleaning process takes several minutes. During cleaning, you may notice that the engine temporarily runs less smoothly and that a somewhat higher engine speed is neces- sary to achieve the accustomed performance. Also, noises may be heard and a slight amount of smoke may emerge from the exhaust, even
