Refueling
Switch off the engine before refueling, otherwise no fuel can be filled into the
tank and a message is displayed.<
When handling fuel, always observe all applicable precautionary measures and regulations. Never transport reserve fuel con- tainers in the vehicle. These could become leaky and cause an explosion or a fire in an acci- dent.<
Fuel filler door
Sports Wagon 1. Unhook the retaining strap*, refer to
page 130.
2. Open the right-hand side panel in the cargo
bay.
3. Pull the knob with the gas pump symbol.
To open and close: press the rear edge of the fuel filler door.
Manual release If an electrical malfunction should occur, you can unlock the fuel filler door manually.
Sedan 1.
In the cargo bay, raise the floor mat and the cover located beneath it.
2. Open the snap fasteners of the right side
panel and take off the side panel.
3. Pull the knob with the gas pump symbol.
Observe the following when refueling When handling fuels, follow the safety precautions posted at the filling station. Otherwise, there is a danger of personal injury or property damage.<
Place the fuel filler cap in the bracket attached to the fuel filler door.
218
When refueling, insert the filler nozzle com- pletely into the filler pipe. Avoid raising the filler nozzle during refueling, otherwise this leads to > premature pump shutoff > a reduced efficiency of the fuel-vapor
recovery system.
The fuel tank is full when the filler nozzle clicks off the first time.
Fuel tank capacity Approx. 18.5 US gal/70 liters, including the reserve capacity of approx. 2.1 US gal/8 liters. 550i: approx. 2.6 US gal/10 liters reserve capacity.
Refuel as soon as possible once your cruising range falls below 30 miles/
50 km, otherwise engine functions are not ensured and damage can occur.<
Fuel filler cap
Closing Fit the cap and turn it clockwise until you clearly hear a click.
Do not crush the band attached to the cap; otherwise, the cap may not properly
seal and fuel vapors can escape.< A message* is displayed if the cap is loose or missing.
Fuel specifications
Do not use leaded gasoline, otherwise permanent damage to the catalytic con-
verter will result. Do not use E85, i.e. fuel that consists of 85% ethanol, or Flex Fuel. Otherwise permanent damage to the engine and the fuel supply sys- tem will result.<
Required fuel
Super Premium Gasoline/AKI 91
This gasoline is highly recommended. However, you may also use gasoline with less AKI. The minimum AKI Rating is 87. If you use gasoline with this minimum AKI Rat- ing, the engine may produce knocking sounds when starting at high outside temperatures. This has no affect on the engine life.Do not use gasoline below the specified minimum quality, otherwise engine dam-
age can result.<
Use high-quality brands Field experience has indicated significant dif- ferences in fuel quality: volatility, composition, additives, etc., among gasolines offered for sale in the United States and Canada. Fuels contain- ing up to and including 10% ethanol or other oxygenates with up to 2.8% oxygen by weight, that is, 15% MTBE or 3% methanol plus an equivalent amount of co-solvent, will not void the applicable warranties with respect to defects in materials or workmanship.
The use of poor-quality fuels may result in drivability, starting and stalling problems especially under certain environmental condi- tions such as high ambient temperature and high altitude. Should you encounter drivability problems which you suspect could be related to the fuel you are using, we recommend that you respond by switching to a recognized high-quality brand such as gasoline that is advertised as Top Tier Detergent Gasoline. Failure to comply with these recommendations may also result in unscheduled maintenance.<

Wheels and tires
Tire inflation pressure
Information for your safety The condition of the tires and the maintenance of the specified tire pressure are crucial not only to the tire's service life, but also to driving com- fort and most importantly, driving safety.
Checking pressure Only check tire inflation pressure when the tires are cold. This means after a maximum of 1.25 miles/2 km driving or when the vehicle has been parked for at least 2 hours. When tires are warm, the tire inflation pressure increases.
Check the tire inflation pressure regularly and correct it as needed, even on the
compact tire*: at least twice a month and before starting long trips. Otherwise driving instability or tire damage, and therefore accidents, can result from incorrect tire inflation pressures. Do not drive with depressurized, i.e. flat tires, except run-flat tires. A flat tire will seriously impair your vehicle's handling and braking response. Attempts to drive on a flat tire can lead to a loss of control over the vehicle.<
After correcting the tire inflation pressure, reinitialize the Flat Tire Monitor, refer to
page 95, or reset the Tire Pressure Monitor, refer to page 97.<
Pressure specifications The tables below provide all the correct inflation pressures for the specified tire sizes at ambient temperature.
The inflation pressures apply to the tire sizes and tire brands respectively
approved and recommended by BMW; a list of these is available from your BMW center.<
220
For correct identification of the right tire infla- tion pressure for your tires, observe the follow- ing: > Tire sizes of your vehicle > Load conditions > Maximum allowable driving speed
Tire inflation pressures for speeds up to 100 mph/160 km/h For normal driving up to 100 mph/160 km/h, adjust pressures to the respective tire inflation pressures listed on the following pages in the column Traveling speeds up to max. 100 mph/ 160 km/h to achieve optimum driving comfort. These pressure specifications can be found on the door post when you open the driver's door.
The permissible top speed for these tire inflation pressures is 100 mph/160 km/h. Do not exceed this speed, otherwise tire dam- age and accidents may result.<
Tire inflation pressures for speeds above 100 mph/160 km/h
In order to drive at maximum speeds in excess of 100 mph/160 km/h, please
observe, and, if necessary, adjust tire pressures for speeds exceeding 100 mph/160 km/h from the relevant table on the following pages. Otherwise tire damage and accidents could occur.< Observe all national and local maximum speed limits, otherwise violations of the law could occur.

Tire Identification Number Tires with DOT codes meet the guidelines of the U.S. Department of Transportation. DOT code:
DOT xxxx xxx 3307
e.g. Manufacturer code for tire make Tire size and tire design Tire age
225
The traction grade assigned to this tire is based on straight-ahead braking traction
tests, and does not include acceleration, cor- nering, hydroplaning, or peak traction charac- teristics.<
Temperature The temperature grades are A, the highest, B, and C, representing the tire's resistance to the generation of heat and its ability to dissipate heat when tested under controlled conditions on a specified indoor laboratory test wheel. Sustained high temperature can cause the material of the tire to degenerate and reduce tire life, and excessive temperature can lead to sudden tire failure. The grade C corresponds to a level of performance which all passenger car tires must meet under the Federal Motor Vehi- cle Safety Standard No. 109. Grades B and A represent higher levels of performance on the laboratory test wheel than the minimum required by law.
The temperature grade for this tire is established for a tire that is properly
inflated and not overloaded. Excessive speed, underinflation, or excessive loading, either sep- arately or in combination, can cause heat buildup and possible tire failure.<
RSC – run-flat tires You will recognize run-flat tires by a circular symbol containing the letters RSC on the side of the tire, refer to page 227.
M+S Winter and all-season tires. These have better winter properties than sum- mer tires.
XL Indicates specially reinforced tires.
Tire age The manufacturing date of tires is contained in the tire coding: DOT ... 3307 indicates that the tire was manufactured in week 33 of 2007. BMW recommends that you replace all tires after 6 years at most, even if some tires may last for 10 years.
Uniform Tire Quality Grading Quality grades can be found where applicable on the tire sidewall between tread shoulder and maximum section width. For example: Tread wear 200 Traction AA Temperature A
DOT Quality Grades Tread wear Traction AA A B C Temperature A B C
All passenger car tires must conform to Federal Safety Requirements in addition
to these grades.<
Tread wear The tread wear grade is a comparative rating based on the wear rate of the tire when tested under controlled conditions on a specified gov- ernment test course. For example, a tire graded 150 would wear one and one-half (1γ) times as well on the government course as a tire graded 100. The relative performance of tires depends upon the actual conditions of their use, how- ever, and may depart significantly from the norm due to variations in driving habits, service practices and differences in road characteris- tics and climate.
Traction The traction grades, from highest to lowest, are AA, A, B, and C. These grades represent the tire's ability to stop on wet pavement, as measured under con- trolled conditions on specified government test surfaces of asphalt and concrete. A tire marked C may have poor traction performance.
226
Tire condition Inspect your tires frequently for tread wear, signs of damage and for foreign objects lodged in the tread. Check the tread depth.
Minimum tread depth The tread depth should not drop below 0.12 in/ 3 mm, although, for example, European legisla- tion only specifies a minimum tread depth of 0.063 in/1.6 mm. At tread depths below 0.12 in/ 3 mm there is an increased risk of high-speed hydroplaning, even when only small amounts of water are present on the road surface. When winter tires wear down past a tread depth of 0.16 in/4 mm, they become perceptibly less suitable for winter conditions. For the sake of safety, new tires should be installed.
In these cases, reduce speed immedi- ately and have wheels and tires thor-
oughly checked. To do so, drive carefully to the nearest BMW center or tire shop that works according to BMW repair procedures with cor- respondingly trained personnel. If necessary, have the vehicle towed there. Otherwise, tire damage can be extremely dangerous to vehicle occupants and other road users.<
Run-flat tires*
Wear indicators at the tread-groove base, refer to arrow, are distributed over the tire's circum- ference and are marked on the side of the tire with TWI – Tread Wear Indicator. If the tire tread has been driven down to the wear indicators, a tread depth of 0.063 in/1.6 mm has been reached.
Wheel/tire damage Please note that low-profile tires cause wheels, tires and suspension parts to be more suscep- tible to road hazards and consequential dam- ages. Unusual vibrations encountered during normal vehicle operation can indicate tire failure or some other vehicle defect. This can, for exam- ple, be caused by driving over curbs. These kinds of problems may also be signaled by other changes in vehicle response, such as a strong tendency to pull to the left or right.
You will recognize run-flat tires by the circular symbol containing the letters RSC on the side of the tire. Run-flat tires consist of partially self-contained tires and special rims. The sidewall reinforce- ment ensures that the tire retains some residual safety in the event of pressure drop and driving remains possible to a restricted degree. To continue driving with a damaged tire: > With Flat Tire Monitor, refer to Indication of
a flat tire, page 96
> With Tire Pressure Monitor, refer to Mes-
sage with low tire inflation pressure, page 98
New wheels and tires
Have new wheels and tires installed only by your BMW center or tire shop that works according to BMW repair procedures with correspondingly trained personnel. If this work is not carried out properly, there is a dan- ger of subsequent damage and related safety hazards. Make sure that the new wheels are bal- anced.<
227
s
Retreaded tires
Recommended tire brands
BMW does not recommend that you use retreaded tires, as driving safety may be impaired. The causes for this include the possi- bly different tire casing structures and the often wide variations in their age, which can result in a limited service life.<
The right wheels and tires
BMW recommends that you use only wheel and tire combinations that BMW
has tested and approved for your particular vehicle. Variations in factors such as manufac- turing tolerances mean that even wheels and tires with identical official size ratings could actually have different dimensions than the approved units – these differences could lead to body contact, and with it the risk of severe acci- dents. If non-approved wheels and tires are used, BMW cannot evaluate their suitability, and therefore cannot be held liable for driving safety.< You can inquire about the right wheel/tire com- bination at your BMW center. The correct wheel/tire combination also affects various systems whose function would other- wise be impaired, e.g. ABS, DSC or xDrive. To maintain good handling and vehicle response, use only tires of a single tread config- uration from a single manufacturer. Following tire damage, have the original wheel and tire combination remounted on the vehicle as soon as possible.
Wheels with electronics for TPM Tire Pressure Monitor When mounting new tires or converting from summer to winter tires or vice versa, only use wheels with TPM electronics, otherwise the Tire Pressure Monitor cannot detect a flat tire, refer to page 97. Your BMW center will be happy to advise you on this subject.
228
Certain tire makes are recommended by BMW depending on the tire size. You can recognize these from the clearly visible BMW marking on the tire sidewall. When used properly, these tires comply with the most demanding standards for safety and vehicle response.
Run-flat tires When mounting new tires, or changing from summer to winter tires or vice versa, use run-flat tires for your own safety. In addition, no spare tire is available in case of a flat tire. Your BMW center will be glad to advise you.
For safety reasons, BMW recommends that you do not have damaged run-flat
tires repaired; they should be replaced. Other- wise it is not possible to rule out occurrences of consequential damage.<
Special characteristics of winter tires BMW recommends winter tires for use in cold winter driving conditions. Although all-season M+S tires provide better winter traction than summer tires, they generally fail to provide the same levels of cold-weather performance as winter tires.
Paying attention to speed
Always observe the maximum permissi- ble speed for the winter tires, otherwise tire damage may occur, which can result in acci- dents.<
Storage Store wheels and tires in a cool, dry place with as little exposure to light as possible. Always protect tires against all contact with oil, grease and fuels. Do not exceed the maximum tire inflation pressure indicated on the side wall of the tire.
Rotating wheels between axles BMW does not recommend moving the front wheels to the rear or vice versa, as otherwise the handling characteristics may be impaired. With tires of different makes and types* such a change is not permissible.
Snow chains* BMW only tests certain fine-link snow chains, classifies them as road-safe and recommends them. Consult your BMW center for more infor- mation. Use is only permissible in pairs on the rear wheels. Observe the manufacturer's instructions when mounting snow chains. Do not exceed a speed of 30 mph/50 km/h with the chains mounted. After mounting snow chains, do not ini- tialize the Flat Tire Monitor, otherwise
incorrect displays can occur. When driving with snow chains, it may be prac- tical to briefly activate DTC, refer to page 92.<

Closing
Close the hood from a height of approx. 16 in/ 40 cm with momentum. It must be clearly heard to engage.
Make sure that the closing path of the hood is clear, otherwise injuries may
result. If you see any signs that the hood is not com- pletely closed while driving your vehicle, you should stop at once and close it securely.<
Under the hood
Never attempt to perform any service or repair operations on your vehicle without
the required professional technical training. If you do not know what repair procedures to follow, have work on your vehicle done only by your BMW center or a workshop that works according to BMW repair procedures with cor- respondingly trained personnel. If this work is not carried out properly, there is a danger of subsequent damage and related safety haz- ards.<

If the engine oil has been topped off, the measurement of the oil level can take up to 30 minutes.
> "Oil level at the minimum! Refill with 1 quart
of engine oil.": Add a maximum of 1 US quart/1 liter of engine oil at the next opportunity, refer to Adding engine oil below. Add at least 0.5 US quart/0.5 liter. Otherwise the oil level control may not display the new value correctly. If the oil level displayed is below minimum, add engine oil immediately. Failure to do so may lead to engine damage. > "Engine oil level too high"*:
Have the vehicle checked immedi- ately, otherwise engine damage may
result if too much oil has been added.<
> "Please observe recalculated service inter-
val for engine oil": Do not add engine oil. Before continuing to drive, note the recalculated remaining mile- age until the next oil change service, refer to Service requirements on page 81. Have the system checked as soon as possible.

Viscosity grades Viscosity is a measure of an oil's flow rating and is specified in SAE grades. The choice of the right SAE grade is based on the climatic conditions in the region in which you normally drive your BMW.
Approved oils belong to the SAE grades 5W-40 and 5W-30.<
Continuous exposure to used oil has caused cancer in laboratory testing.
These oils can be used for driving at all outside temperatures.
For this reason, any skin areas that come into contact with oil should be thoroughly washed with soap and water. Keep oil, grease etc. out of reach of children and observe the warnings on the containers to pre- vent health risks.<
Oil change Have oil changed only at your BMW center or at a workshop that works according to BMW repair procedures with correspondingly trained personnel.
Approved engine oils The quality of the engine oil selected has critical significance for the operation and service life of an engine. BMW continuously approves spe- cific oils after confirming their suitability for use in its vehicles with extensive testing.
Do not use oil additives, as these may result in engine damage.<
Only use approved BMW High Performance Synthetic Oil. If BMW High Performance Synthetic Oil is unavailable, you can add small quantities of other synthetic oils between oil changes. Only use oils of the specification API SM or higher.
Coolant
Do not add coolant to the cooling system when the engine is hot. Escaping coolant
can cause burns.< Coolant is composed of equal parts water and a coolant additive. Not all commercially available additives are suitable for your BMW. Ask your BMW center for suitable additives.
Only use suitable additives, otherwise engine damage may result. The additives
present a health hazard; observe the instruc- tions on the containers.<
Comply with the appropriate environ- mental protection regulations when dis-
posing of coolant additives.<
Checking coolant level 1. Do not open the hood until the engine has
cooled down.
2. Turn the cap of the expansion tank counter-
clockwise to allow any accumulated pres- sure to escape, then continue turning to open.

3. The coolant level is correct when the cool-
ant level is between the MIN and MAX marks, refer to the diagram adjacent to the filler neck.
4.
If the coolant is low, slowly add coolant up to the specified level – do not overfill.
5. Turn the cap until there is an audible click. 6. Have the reason for the coolant loss elimi-
nated as soon as possible.

Maintenance
BMW maintenance system
The BMW maintenance system supports the preservation of the traffic and operating safety of your BMW. The ultimate objective is to ensure economical maintenance by providing the ideal service for your vehicle. Should the day come when you decide to sell your BMW, a complete dealer service history will prove to be an asset of inestimable value.
CBS Condition Based Service Sensors and special algorithms take the differ- ent driving conditions of your BMW into account. Condition Based Service uses this to determine the current and future service requirements. By letting you define a service and maintenance regimen that reflects your own individual requirements, the system builds the basis for trouble-free driving. You can set the Control Display to show remaining distances and times of selected maintenance intervals and legally mandated deadlines, refer to page 81: > Engine oil > Brake pads, front and rear separately > Brake fluid > Vehicle check > Legally mandated inspections depending
on local regulations
Service data in remote control Your vehicle stores the information required maintenance continuously in the remote con- trol during driving. After accessing the data stored in the remote control, your BMW Service Advisor can suggest precisely the right array of service procedures for your own individual vehi- cle. You should therefore hand over the remote control you last used to drive to the BMW Ser- vice Advisor when you take your vehicle in for service.
Make sure the date is set correctly, refer to page 87, otherwise the effectiveness
of CBS Condition Based Service is not ensured.<
