W = up to 167 mph/270 km/h Y = up to 186 mph/300 km/h
Tire Identification Number Tires with DOT codes meet the guidelines of the U.S. Department of Transport. DOT code:
DOT xxxx xxx 3604
e.g. Manufacturer code for tire make Tire size and tire design Tire age
Tire age The manufacturing date of tires is contained in the tire coding: DOT … 3604 means that the tire was produced in the 36th week of 2004. 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. Those grades represent the tire's ability to stop on wet pavement as measured under controlled conditions on specified government test sur- faces of asphalt and concrete. A tire marked C may have poor traction performance.
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 174.
M+S Winter and all-season tires. These have better winter properties than sum- mer tires.
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.
173
s
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 indica- tors are at the level of the tread, the legally per- missible 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 hazard and consequential dam- ages. Unusual vibrations encountered during normal vehicle operation can indicate tire failure or some other vehicle defect. This can, for example, 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.
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. Tire damage can be extremely dangerous for vehicle occupants and other road users.<
You will recognize run-flat tires by a circular symbol containing the letters RSC on the side of the tire. Run-flat tires consist of self-contained tires and special rims. The tire reinforcement ensures that the tire retains some residual safety in the event of pressure drop and driving remains pos- sible to a restricted degree.
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.<
Retreaded tires
BMW does not recommend that you use retreaded tires, since driving safety may
be impaired. The causes for this include the possibly different tire casing structures and the often wide variations in their age, which can result in a limited service life.<
Servicing tires
Unprofessional attempts by laymen to service tires can lead to damage and acci- dents. Have this work performed by skilled pro- fessionals only. The technicians at your BMW center will be glad to assist you with the required professional knowledge and special- ized equipment.<
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
174
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 combination of wheels and tires is another vital factor in ensuring reliable opera- tion of various vehicle systems such as ABS and DSC. To maintain good handling and vehicle response, use only tires of a single tread config- uration from a single manufacturer. After a flat tire, have the original wheel and tire combina- tion remounted on the vehicle as soon as possi- ble.
Recommended tire brands BMW tests certain tire brands for each tire size, classifies them as road-safe and approves them. Consult your BMW center for more infor- mation. Observe any country-specific regulations, e.g. on making a corresponding entry in the vehicle documents. The factory-mounted tires have been specially selected to provide optimized performance when installed on your vehicle; if properly cared for, they will provide a combination of safety and excellent ride comfort.
Run-flat tires When mounting new tires or changing from summer tires to winter tires or vice versa, use run-flat tires because there is no spare tire in case of a flat. 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.<
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.
Pay attention to speed
Do not exceed the maximum permissible speed for the winter tires, otherwise tire
damage may occur, which can result in acci- dents.<
Storage Always 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.
Snow chains* BMW only tests certain fine-link snow chains, classifies them as road-safe and approves them. Consult your BMW center for more infor- mation. BMW recommends using these approved, fine-link snow chains. Use is only permitted in pairs, with winter tires 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 snow chains are mounted, do not initialize the Flat Tire Monitor.
When driving with snow chains, it can be useful to activate the DTC temporarily, refer to page 78.<
175
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 fol- low, 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.<
Hood
Releasing
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, as 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.<
Pull the lever located under the left side of the instrument cluster.

Engine oil The engine oil consumption is dependent on driving style and driving conditions.
Checking oil level 1. With the engine at operating temperature, i.e. after at least 6 miles/10 km of uninter- rupted driving, park the vehicle in a horizon- tal position.
2. Switch off the engine. 3. After approx. 5 minutes, pull out the dip-
stick 4 and wipe it off with a clean lint-free cloth, paper towel, or similar material.
4. Carefully push the dipstick all the way into
the guide tube and pull it out again.
The oil should extend to between the two marks on the dipstick.
The oil quantity between the middle of the two marks on the dipstick is approx. 1.6 US quarts/ 1.5 liters.
177
Do not exceed the upper marking on the dipstick, otherwise an overfilling of oil can
damage the engine.<
Adding engine oil
Do not top off the oil until the oil level has dropped to just above the lower marking on the dipstick. In this area a message also appears on the Control Display.
Refill the oil within the next 125 miles/ 200 km, otherwise engine damage could
result.<
Continuous exposure to used oil has caused cancer in laboratory testing.
For this reason, any skin areas that come into contact with oil should be thoroughly washed with soap and water. Store oil, grease, etc., well out of the reach of children; always observe all warning labels on the containers.<
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.
Specified 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. Use only approved BMW High Performance Synthetic Oil. If you are unable to obtain BMW High Perfor- mance Synthetic Oil, you can add small
178
amounts of another synthetic oil between oil changes. Use only oils with the API SH specifi- cation or higher.
Ask your BMW center for details concern- ing the specific BMW High Performance Synthetic Oil or synthetic oils which have been approved.< You can also call BMW of North America at 1-800-831-1117 or visit this website: www.bmwusa.com to obtain this information.
Viscosity ratings Viscosity is the oil flow rating as defined in SAE classes. The selection of the correct SAE class depends on the climatic conditions in the area where you typically drive your BMW.
Approved oils are in SAE classes 5W-40 and 5W-30.<
These oils may be used for driving in all ambient temperatures.
Coolant
Do not add coolant to the cooling system when the engine is hot. Escaping coolant
can cause burns.< Coolant consists of water and the addition of antifreeze and anticorrosion agent. Not all com- mercially available additives are suitable for your BMW. Ask your BMW center for suitable additives.
Only use suitable additives, as 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. The engine must be at ambient tempera-
ture.
2. Turn the cap of the expansion tank counter-
clockwise to allow any accumulated pres-
Brake pads
The warning lamp lights up in spite of the handbrake being released; a mes- sage appears on the Control Display: The brake pads have reached their minimum pad thickness. Have brake pads replaced immediately.
Display of the previously described malfunction on Canadian models.
For your own safety: use only brake pads that BMW has approved for the corre-
sponding vehicle model. As BMW cannot assess the suitability of other brake pads for use on your vehicle, we are unable to assume continued responsibility for the vehicle's oper- ating safety if non-approved pads are installed.<
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
The BMW maintenance system
The BMW maintenance system supports the preservation of the traffic and operating safety of your BMW. The service schedule also includes operations related to the vehicle's comfort and convenience features, such as replacement of the filters for the inside air. 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, you will find that a complete dealer service history is 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 times or distances of selected main- tenance intervals and legally mandated dead- lines, refer to page 66: > Engine oil > Brakes, front and rear separately > Microfilter/activated-charcoal filter > Brake fluid
180
> Spark plugs > Vehicle check > Legally mandated inspections depending
on local regulations
Your vehicle stores this information continu- ously in the master key while the vehicle is being driven. After accessing the data stored in the master key, your BMW Service Advisor can suggest precisely the right array of service pro- cedures for your own individual vehicle. You should therefore hand over to the BMW Service Advisor the key you last used to drive when you take your vehicle in for service.
Make sure the date in the Control Center is always set correctly, refer to page 74, as otherwise the effectiveness of CBS Condi- tion Based Service is not ensured.<
Service and Warranty Information Booklet for US models and Warranty and Service Guide Booklet for Canadian models Please consult your Service and Warranty Infor- mation Booklet for US models and Warranty and Service Guide Booklet for Canadian models for additional information on service require- ments.
BMW recommends that you have service and repair operations performed at your
BMW center. Take the time to ensure that these service pro- cedures are confirmed by entries in your vehi- cle's Service and Warranty Information Booklet for US models and Warranty and Service Guide Booklet for Canadian models. These entries verify that your vehicle has received the speci- fied regular maintenance.<
Event Data Recorders Your vehicle may be equipped with one or more sensing and diagnostic modules or a recording device capable of recording or transmitting cer- tain vehicle data or information. In addition, if you have a Subscription Service Agreement for the BMW Assist system, certain vehicle infor- mation may be transmitted or recorded in order to provide such services.
Care Important information on the care and mainte- nance of your BMW is contained in the Caring for your vehicle brochure.
OBD Socket
The Onboard Diagnostics OBD interface socket is located on the left of the driver's side under the instrument panel and under a cover. The cover has the letters OBD on it. The purpose of the OBD system is to ensure proper operation of the emission control sys- tem for the vehicle's lifetime. The system mon- itors emission-related components and sys- tems for deterioration and malfunction.
An illuminated lamp informs you of the need for service, not of the need to stop the vehicle. However, the systems
should be checked by your BMW center at the earliest possible opportunity.
Display of the previously described malfunction on Canadian models.
Under certain conditions, the indicator will blink or flash. This indicates a rather severe level of engine misfire. When this occurs, you should reduce speed and consult the nearest BMW center as soon as possible. Severe engine mis- fire over only a short period of time can seri- ously damage emissions control components, especially the catalytic converter.
When the fuel filler cap is not properly tightened, the OBD system can detect the vapor leak and the indicator will light up. If the filler cap is subsequently tightened, the indicator should go out within a few days.<

LEDs light-emitting diodes Light-emitting diodes installed behind translu- cent lenses serve as the light source for many of the controls and displays in your vehicle. These light-emitting diodes, which operate using a concept similar to that applied in conventional lasers, are officially designated as Class 1 light- emitting diodes.
Do not remove the covers, and never stare directly into the unfiltered light for
several hours, as this could result in irritation of the retina.<
Changing wheels
Safety precautions in the event of a flat tire or wheel change: Park the vehicle as far as possible from passing traffic and on solid ground. Switch on the hazard warning flashers. Lock the steering wheel in straight-ahead set- ting of the wheels. Apply the handbrake and engage first gear, reverse gear or selector lever position P. Have all vehicle occupants get out of the vehicle and ensure that they remain outside the imme- diate area in a safe place, such as behind a
guardrail. If a warning triangle or portable hazard warning lamp is required, set it up on the roadside at an appropriate distance from the rear of the vehi- cle. Comply with all safety guidelines and regu- lations. Change the wheel only on a level, firm surface which is not slippery. The vehicle or the jack could slip to the side if you attempt to raise the vehicle on a soft or slippery surface such as snow, ice, tiles, etc. Position the jack on a firm support surface. Do not use a wooden block or similar object as a support base for the jack, as this would prevent it from extending to its full support height and reduce its load-carrying capacity. To avoid serious or fatal injury: never lie under the vehicle, and never start the engine while it is supported by the jack.<
What you will need To avoid rattling noises later on, note the posi- tions of the tools before removing them, then return them to their initial positions after com- pleting work.
1 Chock* 2 Vehicle jack* 3 Lug wrench* The tools are located in the hollow of the com- pact wheel. 1. Lift up floor mat or floor panel flap and cover
located beneath it.
2. Take out the required tools. 3. After using the tools, return then to the stor-
age space.

3. Loosen the lug bolts a half turn.
Jacking up vehicle 1. Position the vehicle jack at the jacking point closest to the wheel so that the entire sur- face of the jack base rests on the ground perpendicularly beneath the jacking point.
The vehicle jack is designed for changing wheels only. Do not attempt to raise another vehicle model with it or to raise any load of any kind. To do so could cause accidents and personal injury.<
3. Jack the vehicle up until the wheel you are
changing is raised from the ground.
Mounting a wheel 1. Unscrew the lug bolts and remove the
wheel.
2. Remove accumulations of mud or dirt from
the mounting surfaces of the wheel and hub. Also clean the lug bolts.
3. Position the new wheel or compact wheel. Secure the wheel by turning at least two lug bolts into opposite bolt holes. When you mount wheels other than Genu- ine BMW light-alloy wheels, different lug bolts may also be required.
4. Screw in the remaining lug bolts. Tighten all
the bolts securely in a diagonal pattern.
5. Lower the vehicle and remove the jack from
beneath the vehicle.
After mounting 1. Tighten the lug bolts in a diagonal pattern.
To ensure safety, always have the lug bolts checked with a calibrated
torque wrench as soon as possible to ensure that they are tightened to the speci- fied torque. The tightening torque is 88.5 lb ft/120 Nm.<
2. When stowing the wheel and tools in the
vehicle, execute these steps in the reverse order.
186
3. Check and correct the tire inflation pressure
at the earliest opportunity.
Protect valve stems and valve stem seal caps against dirt and contamina- tion. Dirt in valve stems is a frequent source of gradual air loss.<
4. Reinitialize the Flat Tire Monitor, refer to
page 80.
5. Replace the damaged tire with a new one as
soon as possible and have the new wheel balanced.
Driving with compact wheel Drive reservedly and do not exceed a speed of 50 mph/80 km/h. The driving characteristics change, for example reduced track stability on braking, extended braking distance, and altered self-steering characteristics in the limit range. In conjunction with winter tires, these characteristics are more pronounced.
Only one compact wheel may be mounted. You should re-equip with
wheels and tires of the original size as quickly as possible.<
Vehicle battery
Battery care The battery is 100% maintenance-free, i.e., the electrolyte will last for the life of the battery when the vehicle is operated in a temperate cli- mate. Your BMW center will be glad to advise in all matters concerning the battery.
Charging battery Only charge the battery in the vehicle via the terminals in the engine compartment with the engine off. Connections, refer to Jump starting on page 190.
Disposal
