Introduction [for SULEV (PZEV) only]

Certain 2014 428i models are certified to California’s stringent Super Ultra Low Emission Vehicle (SULEV) standards and also qualify as a Partial Zero Emission Vehicle (PZEV) under the California Air Resources Board Zero Emission Vehicle program. In addition to very low tailpipe and zero-evaporative emissions, this PZEV certification includes a unique warranty when the vehicle is registered in California and certain other states, as indicated in the SULEV (PZEV) section beginning on page 35. SULEV (PZEV) models registered in Delaware, Oregon, Pennsylvania and Washington are covered by the California Emission Warranty beginning on page 26.

The emission certification standard can be verified on the Vehicle Emission Control Information label located in the engine compartment. A representative label is shown below; the SULEV (PZEV) certification is stated after the word “California.”

BMW Ultimate Service™

BMW Ultimate Service leads the industry in providing owners with incredible value and peace of mind. This service includes:

䉯 The BMW Maintenance Program: No cost

factory-recommended maintenance for 4 years/50,000 miles from the original in-service date, whichever comes first.

䉯 BMW Roadside Assistance: No-cost 24/7

on-the-road assistance for 4 years/unlimited miles from the original in-service date. Also includes trip-interruption benefits as well as trip routing services.

䉯 New Vehicle Limited Warranty: Limited

coverage for defects in materials and workmanship for 4 years/50,000 miles from the original in-service date, whichever comes first. Repairs will only be made at authorized BMW centers using Original BMW Parts.

The BMW Maintenance Program

The BMW Maintenance Program is a benefit designed to help reduce the cost of ownership. This program has been devised with the following objectives: to maximize vehicle safety, reliability, and resale value by minimizing breakdowns resulting from wear, and minimizing cost and inconvenience by computing maintenance intervals based upon the specific manner in which each individual vehicle is driven.

A 2014 2, 4, 6 Series and Z4 vehicle purchased from an authorized BMW center in the United States (including Puerto Rico) is covered by the BMW Maintenance Program for 48 months or 50,000 miles, whichever occurs first. Coverage begins on the date of first retail sale or the date the vehicle is first placed into service as a sales demonstrator, Aftersales Mobility Program (AMP) Vehicle or BMW Group company vehicle, whichever is earlier.

Any authorized BMW center in the United States (including Puerto Rico) will perform the scheduled and/or additional maintenance services on your vehicle at no expense to you so long as your vehicle qualifies for coverage under the BMW Maintenance Program.

Coverage

The BMW Maintenance Program covers all factory recommended maintenance, as determined by the Condition Based Service (CBS) system. Additional specific items that need replacement due to normal wear and tear, and that are not covered by the original New Vehicle Limited Warranty - such as brake pads, brake rotors, and wiper blade inserts - are included, provided wear and tear exceeds BMW wear limits. Any applicable adjustments required due to normal operating conditions are also included. See pages 8-10 of this booklet for additional information.

Exclusions from coverage include the following: 䉯 Items reimbursable under your New Vehicle

Limited Warranty

䉯 Gasoline and gasoline additive 䉯 Windshield washer additive (except when in

conjunction with scheduled maintenance)

䉯 Tires, wheel alignment, tire balance and

rotation

䉯 Parking brake shoes/linings 䉯 Reset Tire Pressure Monitor 䉯 Wear and tear of soft trim items, such as:

seats, carpets, moldings, headliner, door panels and all chrome trim

䉯 Damage, including consequential, which

results from negligence, improper operation of the vehicle, wear and tear or deterioration due to driving habits or conditions, improper repair, environmental influences, flood, accident or fire damage, road salt corrosion, alteration, installation of non-genuine BMW accessories, or use of improper, poor quality or contaminated fuel

䉯 Altered or unreadable Vehicle Identification

Number (VIN) or odometer irregularities or vehicles where the true mileage cannot be determined

䉯 Maintenance or repair after the vehicle is

deemed a total loss

䉯 Maintenance or repairs performed by other

than an authorized BMW center within the United States (including Puerto Rico)

䉯 “Topping off” low fluids (e.g., engine oil,

antifreeze, washer fluid, etc.) except when done in conjunction with a scheduled maintenance or other required maintenance work (as outlined in the customized maintenance checklist printout) that is performed during an applicable Maintenance Program period

䉯 Vehicles used in competitive events 䉯 Oil changes performed outside the

recommended maintenance intervals as indicated by the Condition Based Service

Maintenance Upgrade Option

Please contact your authorized BMW center for information regarding the purchase of optional Maintenance Program Upgrades. Eligibility and coverage exclusions may apply.

Intervals

Time intervals should be followed using the maintenance intervals as indicated by the BMW Condition Based Service.

Maintenance intervals on motor vehicles have conventionally been specified based upon accumulated mileage. However, driving conditions have a major influence on routine maintenance requirements; distance traveled is only one of the significant factors. A vehicle driven for 50,000 miles of short trips in the city with numerous cold starts, prolonged periods of idling, stop-and-go driving, and high engine speeds during acceleration requires more frequent maintenance intervals than a vehicle driven for 50,000 miles for long distances at low engine speeds primarily at operating temperature.

The advanced technologies at BMW have led to the development of the unique BMW Condition Based Service (CBS) system which computes the actual optimum maintenance requirements based not only upon the accumulated mileage, but taking into account important factors such as high or low engine speeds, short or long trip driving.

Condition Based Service (CBS)

CBS is a further development of the Service Interval Indicator System.

The remaining times for selected maintenance tasks as well as any legally prescribed dates are displayed to you individually:

䉯 Engine oil 䉯 Brakes - front and rear separately 䉯 Brake fluid 䉯 Vehicle check 䉯 Required State Inspection(s)

CBS thus determines the current and future maintenance requirements. This data can also be read from the vehicle key by your BMW Service Advisor and used to propose the optimum scope of maintenance.

Disconnecting the battery during periods of

long-term storage will interrupt the calculation of time-based services. BMW recommends that you have all items requiring time-based maintenance, such as brake fluid and possibly also the engine oil and microfilter, brought up to date by your authorized BMW center. Also see the section on battery care on page 11 of this Booklet.

Special Note – Maintenance Intervals

The maintenance requirements for your vehicle are determined dynamically by the Condition Based Service (CBS) system. The maintenance items stated herein reflect the latest information available at the time of the printing of this Booklet, and are subject to change.

2014 6 Series and Z4 vehicles built prior to July 2013 utilized a different CBS “connected service item” interval as detailed on page 10.

The completion of certain subsequent maintenance items or services, as required to properly maintain your vehicle, will be specified at intervals computed by the BMW Condition Based Service system as follows:

䉯 Oil Service: Engine oil should be changed with

the engine at operating temperature.

All 2014 model year 2, 4, 6 Series and Z4 vehicles are factory-filled with BMW High Performance Synthetic oils. We recommend BMW High Performance 5W-30 Synthetic Oil (BMW part number 07 51 0 017 866) for regular scheduled engine oil changes.

BMW recommends that you check your engine oil level whenever you add fuel to your vehicle. For information on checking your engine oil level, refer to your vehicle’s Owner’s Manual.

If you need to add oil between oil changes and BMW High Performance Synthetic Oil is unavailable, for the purpose of topping up the engine oil level only, BMW recommends use of one of the below-listed synthetic oils:

The synthetic oils listed below meet BMW’s Long-life rating LL01 (API rating SL):

䉯 Castrol Syntec European Formula SAE 0W-30 䉯 Castrol Edge with SPT SAE 5W-40 䉯 Mobil 1 SAE 0W-40 䉯 Pennzoil Platinum European Formula Ultra

SAE 5W-30

䉯 Valvoline SynPower SAE 5W-30

The choice of the right SAE grade is based on the climatic conditions in the region in which you normally drive your BMW. To best determine which SAE grade is best suited for your vehicle, contact an authorized BMW center.

If you are unable to obtain a recommended synthetic oil from the list above, for the purpose of topping up the engine oil level only, use only a synthetic oil with an API rating of SM or higher.

The following maintenance services: – Brake Fluid Service;

– Intake Air Cleaner Service; – Oxygen Sensor Service; – Spark Plug Service; – Ventilation Microfilter Service,

must be performed when required as indicated by the following as applicable:

䉯 The specified CBS engine oil service counter

interval

䉯 The time interval (the first occurrence based

on the vehicle’s production date)

䉯 The stated mileage for a “non-connected”

maintenance service

Refer to pages8-10foradditional information. Additionally,

– The engine coolant has a long-term rating and

does not need to be changed except for system repairs.

– The automatic and manual transmissions, and

the all-wheel drive transfer cases installed in BMW vehicles are factory filled with long-term rated fluids. The transmission long-term rated fluid does not need to be changed except when necessary during repairs to the transmission. The transfer case long-term rated fluid does not need to be changed except when indicated by the vehicle or when necessary during repairs to the transfer case.

For your convenience, you may also wish to have your authorized BMW center perform any necessary operations to fulfill any state inspection requirements in your area, concurrent with the maintenance services specified above during other repairs. Should you request more

frequent maintenance service, the cost of these services will not be covered by the Maintenance Program.

BMW has applied the most modern technological advances not only to the design and production of your vehicle, but also to computing of the optimum maintenance interval for your type of operations and driving style. Your authorized BMW center has made a substantial investment in unique BMW special service tools to enable BMW factory trained service technicians to perform quality repairs on your BMW in minimal time, to help maximize your satisfaction with your BMW, its longevity, and resale value.

Quality Certification I

For a detailed list of items inspected, refer to the Quality Certification I form provided to the Owner at time of delivery. A copy of the form is on file at the selling authorized BMW center.

and, when applicable, adjusting the engine idle. We suggest having this work performed by your authorized BMW center, perhaps while regular maintenance is performed. Your authorized BMW center can also recommend a gasoline additive that will provide sufficient detergency.This recommended unscheduled maintenance which may be necessitated by use of inappropriate fuels is not required in order to maintain the emission warranty. It also is not covered by your vehicle’s warranty because no defect in material or workmanship or component failure is involved.

Maintenance Service Summary

The Condition Based Service (CBS) system will determine the requirement for performing the maintenance services described in this section, ending on page 10. These services may be required either individually or in conjunction with other maintenance services.

Maintenance services are performed as outlined in this section, based on intervals of either time, mileage or after performing a specified number of previous services. These intervals correspond to the latest information available when this Booklet was printed. Maintenance intervals are subject to change with newer vehicles or may also apply retroactively. Your authorized BMW center will be able to advise and perform maintenance services as required by the most recent information that applies to your vehicle.

The maintenance services “connected to a specific CBS engine oil service,” as outlined below, apply to vehicles built as of July 2013.

6 Series and Z4 vehicles built prior to July 2013 utilized a different CBS “connected service item” interval as detailed on page 10.

Fuel Quality – Gasoline (gasoline engines only)

Only use fuels advertised to have adequate detergency and low alcohol (such as ethanol) content. Please refer to your owner’s manual for important information on the fuel recommended for use in your vehicle.

12 Volt Battery Care

If your car is driven only for short distances of less than 10 miles over a prolonged period of time, without an occasional drive at highway speeds, the engine’s charging system will not maintain the battery. Insufficient use of the vehicle could result in short term starting problems and, in the long term, could damage the battery.

In case the car is not operated for several weeks, it is advisable to:

䉯 consider using a proper trickle charger,

following the charger manufacturer’s instructions, to maintain the battery’s state of charge; or

䉯 consult your authorized BMW center regarding

battery removal. Once removed, the battery must be charged and stored in a cool, dry place where it can be protected from freezing. If the battery will be stored for over 3 months, it must be recharged every 3 months, or else it will become damaged and useless.

Please consult with your authorized BMW center for further guidance and information.

During manufacture, metal exterior body parts receive an additional corrosion protection coat. Hood, trunk, doors and other body parts are coated with PVC and sealed from the outside.

All floor panels receive a resilient coating of PVC for maximum protection against damage due to stones, etc.

Corrosion protection materials tested over many years are applied to the surfaces of cavities and to the entire underside of the vehicle during and after assembly.

For additional information on the 12-year unlimited mileage anti-corrosion warranty see the Warranty Section of this Booklet (page 22).

Restoring corrosion protection

Please take care that anti-corrosion material is replaced when your car is repaired after body or chassis damage.

BMW will not accept any liability for repair of, or damage caused by, any parts and accessories not approved by BMW.

Underbody maintenance

Corrosion Protection

Extensive corrosion protection measures implemented by BMW now make it possible to offer a 12-year unlimited mileage anti-corrosion warranty against rust perforation on your vehicle provided that the vehicle is properly maintained. Information on proper maintenance is available in this Booklet and your vehicle’s Owner’s Manual.

The major degree of corrosion protection is due to the electrophoretic dip painting process which cathodically deposits paint particles on all body parts, attracting paint particles into the minutest cavities or seams. Body parts are designed to provide optimum corrosion protection.

The underbody has to be cleaned at least once a year, in Spring, with plain water in order to remove mud, chemical sediments and other deposits. If those materials are not removed, corrosion (rust) will occur on metal components.

Your authorized BMW center can do this anti-corrosion service for you.

Do not apply additional undercoating or

rust-proofing on or near the exhaust manifold, exhaust pipes, catalytic converter or heat shields. During driving, the substance used for undercoating could overheat and cause a fire.
