Service and Warranty Information Booklet (US models)/Warranty and Service Guide Booklet (Canadian models) For detailed information on required maintenance items and the work involved, please refer to the Service and Warranty Information Booklet (US models) or to the Warranty and Service Guide Booklet (Canadian models). Depending upon operating conditions, it may be advisable to have the body checked for damage from rocks or gravel at the same time as a precaution against rust.
Have your BMW center do the maintenance and repair.
Your BMW center is always informed on the latest maintenance work and repair techniques and is equipped with the required special tools. In addition, checking parts known from experience to be subject to wear is a permanent part of the maintenance specifications. Be sure that all maintenance work is confirmed in the Service and Warranty Information Booklet (US models) or the Warranty and Service Guide Booklet (Canadian models). These entries will constitute your proof that the vehicle has received regular maintenance. They are also required for warranty claims.<
Washing your vehicle You can wash your BMW by hand or in an automatic car wash – even when it is new. Car wash systems that do not employ brushes are preferable. Loosen and remove tough dirt and dead insects before washing the vehicle. To prevent spots, avoid washing when the hood is still warm, or immediately after and during exposure to strong sunlight. If a brushless car wash is unavailable and a brush car wash must be used, modern systems with soft brushes are preferable. In order to protect the convertible top, special waxing programs may not be selected for the M roadster. The small amount of beading wax always used in automatic car washes will not harm your vehicle's finish.
After washing the vehicle, apply the brakes briefly to dry them.
Braking efficiency might otherwise be reduced by the moisture and the brake discs could also be corroded.<
116nCaring for your vehicle
When using an automatic car wash, be sure that: > The car wash system is suited for the
dimensions of your vehicle.
> No damage will occur on vehicles
with attached body accessories (such as spoilers or antennas). Consult the car wash operator if necessary.
> The wheels and tires of your vehicle cannot be damaged by the convey- ance devices of the car wash system. > The vehicle is cleaned with minimum
brush pressure, and ample water is available for washing and rinsing.
Parts of the vehicle which are inacces- sible to the automatic washer – such as door sills, door and hood edges, etc. – should be cleaned by hand. In the winter months, it is especially important to ensure that the vehicle is washed on a regular basis. Large quan- tities of dirt and road salt are difficult to remove, and they also cause damage to the vehicle.
If spray wands or high-pressure washers are used, be sure to
maintain an adequate distance between the spray source and the vehicle's surface. Inadequate distance and excessive pressure can damage or weaken the finish, making it more susceptible to subsequent attack. In addition, moisture could penetrate to vehicle components, leading to long- term damage.<
When cleaning the headlamps, please observe the following:
> Do not rub dry (this causes scratches)
and never use abrasives or strong solvents to clean the covers.
> Remove dirt and contamination (such as insects) by soaking with BMW Car Shampoo and then rinsing with plenty of water.
> Always use a deicer spray to remove
accumulated ice and snow – never use a scraper.<
Caring for your vehicle
Cleaning and care of the convertible top – M roadster The appearance and life of the convert- ible top are highly dependent on its proper care and operation. You should pay particular attention to the following instructions if your vehicle has a light- colored top. Protect the vehicle from exposure to intense sunlight whenever possible by parking it in the shade. This will prevent the paint, rubber and fabric-covered parts from being attacked. Never fold up the convertible top and store it in the convertible top compart- ment when wet, dirty or frozen, since mildew stains and rub spots may result. To prevent the formation of creases in the rear window and mildew stains in the fabric, do not leave the top folded in the convertible top compartment for extended periods. If the vehicle will be parked for lengthy periods in an enclosed space, be sure that the convertible top is dry and that there is adequate ventilation.
Clean off bird droppings immediately, since they attack the convertible top and cause the rubber seals to swell due to their caustic characteristics. Besides water, treat rubber seals only with talcum powder, rubber care prod- ucts or silicone spray, particularly when they feel dry or tend to stick. Eliminate noises such as squeaks with lubricant spray. Never use sharp-edged objects to clean snow or ice from the rear window. The use of deicing spray is not approved. Due to the danger of damage and discoloration, do not apply adhesive tape, stickers, etc., to the window or cover it with plastic film. Depressions and discoloration may occur in the convertible top as a result of improper maintenance and cleaning or as the result of stresses from exces- sive use. The convertible top and its seams may also develop leaks. These occurrences are not covered by the warranty. For repairs, please consult your BMW center.
117n
Special wash for the top In the case of more extensive dirt, which is especially visible on light- colored top materials, clean the top with the BMW Convertible Cleaning Set. Please proceed as follows: Spray the convertible top with the cleaning agent and then rub with a well- dampened sponge using circular motions until a foam develops. Then you can finish washing the vehicle in an automatic car wash. After three to five washings the convertible top should be treated with a special impregnating spray. Please follow the instructions on the spray can.

118nCaring for your vehicle
Rear window cleaning While the roadster's rear window has the advantage of being extremely flex- ible, there is the disadvantage that it has a relatively soft surface. For this reason, clean the rear window only with a soft, antistatic cloth or with BMW Convertible Rear Window Cleaner. If you wash the vehicle frequently in brush car washes, and in particular in those with hard brushes, faint scratches in the rear window may result. With the window replacement system you can replace a heavily scratched window at a relatively low price. Please contact your BMW center for additional information.
Do not use spot removers, paint thinners, solvents, gasoline or
similar substances for removing spots from the convertible top or from the rear window. These materials destroy the rubber seals, which will lead to leaks. Use only BMW-approved cleaners.<
Exterior finish To provide effective corrosion protec- tion, multilayer paintwork is applied at the factory. Cataphoretic immersion priming techniques are supplemented using special body-cavity protectants, with the application of specially-devel- oped and extensively tested materials. A layer of flexible PVC is first applied to the undercarriage. Following this, a comprehensive undercoating treat- ment with a wax-based protectant is applied. Regular care makes an important contribution to maintaining the safety and value of your vehicle. Increasing awareness of the effects of harmful environmental factors on vehicle finishes have led paint and vehicle manufacturers to initiate programs designed to further improve the durability of their finishes. Despite this, environmental factors which occur locally or regionally can have negative effects on the finish of your vehicle. These should guide you in determining the frequency and extent of your efforts to maintain the vehicle finish. Depending upon material and type of impact (perforation of paint layer), physical stresses from sand, road salt,
gravel, etc., can cause corrosion to start extending beneath the finish, starting at the point of impact. Road dirt, tar spots, dead insects, animal droppings (strong alkali concen- tration) and tree excretions (resins and pollen) all contain substances capable of causing damage when allowed to remain on the finish of your vehicle for any period of time (spots, etching, flaking, separation in the top coat). In industrial areas, deposits of flue dust, lime, oily soot, precipitation containing sulfur-dioxide (acid rain) and other envi- ronmental pollutants will damage the vehicle's finish unless adequate care is provided – even though this is generally limited to the outside horizontal surfaces. In coastal regions, high levels of atmo- spheric salt and humidity promote corrosion. In the tropics, in addition to ultra-violet radiation and high humidity, tempera- tures over +105 7 (+40 6) in the shade are common. Under those condi- tions, light paints can reach tempera- tures up to +175 7 (+80 6) and dark paints up to +250 7 (+120 6).
Waxing your vehicle Protect the finish using carnauba or synthetic-based waxes only. The best way to determine when the finish needs to be waxed is by noting when water stops beading on the surface. You can use a glass cleaner to remove any wax or silicone that may have been left on the windows during waxing.

your BMW center.<
Caring for your vehicle
Caring for the vehicle finish Regular washing is a preventive measure against long-term effects from substances which are harmful to the vehicle's finish, especially if you drive your vehicle in areas with high levels of air pollution or aggressive natural substances (tree resins, pollen). Nevertheless, you should immediately remove especially aggressive substances. Failure to do so can lead to changes in the paint's chemical struc- ture or to discoloration. Gasoline spilled during refueling, oil, grease and brake fluid should always be cleaned away immediately, as should bird droppings (finish damage). Any contamination remaining on the surface of the vehicle will be especially conspicuous after washing. Use cleaning fluid or alcohol with a clean cloth or cotton pad to remove. Remove tar spots with tar remover. After cleaning, the affected areas should be waxed to ensure continued protection.

Paint damage You can touch up minor paint flaws with BMW spray paint or a BMW touchup stick. The color code for your vehicle is provided on a tag located near the vehicle data plate and on the first page of the Service and Warranty Information Booklet (US models) or the Warranty and Service Guide Booklet (Canadian models). Damage caused by flying stones, scratches, etc., must be touched up without delay to prevent rust from forming. If corrosion has started to form in an area with paint damage, remove all rust and clean the area. Finally, apply the finish coat. Wait a few days, then polish the repaired area. Finish by applying a wax preservative. More extensive paint damage should be repaired professionally in accor- dance with the manufacturer's instruc- tions. Your BMW center uses original BMW finish materials in accordance with approved repair procedures.
Use the cleaning and car-care products that you can obtain at
your BMW center.<
120nCaring for your vehicle
Window care You can use window and glass cleaner to clean inside window surfaces and mirrors without smearing and streaking. Never use polishing pastes or abrasive (quartz) cleansers on mirror lenses! Clean the wiper blades with soapy water. The wiper blades should be replaced twice a year, before and after the cold season.
Use only wiper blades which have been approved by BMW.<
The safety belts should be cleaned with a mild soap and water solution without being removed from the vehicle. Never attempt chemical or dry cleaning, since this could cause damage to the belt fabric. After cleaning, never allow the inertia reels to retract the belts until they are completely dry. Dirty safety belts prevent the inertia reel mechanism from retracting the strap properly, and thus constitute a safety hazard. Heavily soiled floor carpets and mats* can be cleaned with an interior cleaner. The floor mats can be removed from the vehicle for cleaning. Please use only a damp cloth to clean wooden fascia panels and components. Follow up by drying with a soft cloth.
Use the cleaning and car-care products that you can obtain at
your BMW center.<
Caring for other vehicle components and materials Light-alloy wheels should be treated with alloy wheel cleaner, particularly during the winter months. Do not use aggressive products containing acids, strong alkalis or abrasives. Alloy wheels should not be cleaned with a steam jet operating at temperatures in excess of +140 7 (+60 6). Follow the manufac- turer's instructions. If your vehicle is equipped with chromed parts* such as window frames, door handles, etc., clean these parts thor- oughly with plenty of water and, if they are exposed to the effects of salt, also with a shampoo additive. Use chrome polish for additional treatment. Plastic components, vinyl upholstery, the headliners, lamp lenses, the clear cover of the instrument cluster and components with a sprayed dull black surface can be cleaned with water (add plastic shampoo as required). Do not allow moisture to soak through the seats or headliner. Never use solvents such as lacquer thinner, heavy-duty grease remover, fuels, etc. Rubber components should be cleaned with water only; a rubber treatment or silicone spray may also be applied.
The buildup of an electrostatic charge on the seat covers, particularly if atmo- spheric humidity is low, can give the occupants an unpleasant electric shock if they touch metal body parts after leaving the vehicle. Although this is not dangerous in any way, it can be avoided by touching a bare or polished metal part of the vehicle while getting out.
Caring for your vehicle
Care of upholstery materials Depressions formed in the upholstered materials in the course of everyday use can be brushed up working with a lightly dampened brush "against the nap." The tendency of the pile to lie in a particular direction on velour upholstery is not a quality defect, and, just as on home textiles or clothing, cannot be avoided. Fuzz on upholstery materials, rubbed-in fabric or suede residues can be removed with a fuzz or Velcro® brush. A cleaning glove is available for particu- larly "stubborn" lint. Remove spots and larger soiled areas immediately with luke-warm water, an interior cleaner, a spot remover or appropriate cleaning fluid. Brush the fabric afterwards to restore its appearance. If the vehicle will be stored for an extended period or if it is exposed to intense sunlight, cover all the seats or the windows to prevent fading (road- ster: convertible top closed).

Leather care The leather* upholstery used by BMW is a natural product of the highest quality, processed using state-of-the- art methods to ensure that it will main- tain its high quality for years to come, provided that it is properly cared for. As this product is manufactured using natural materials, you must make allow- ances for special characteristics and possible surface irregularities. You should also bear in mind that this kind of material requires special care and attention. Regular cleaning and care are essen- tial, since dust and road dirt act as abrasives in the pores and creases of the material. This leads to wear spots and premature brittleness on the surface of the leather. We therefore suggest that you clean the leather with a vacuum cleaner or dust cloth at frequent intervals. For cleaning, use BMW leather cleaning foam. Since dirt and grease gradually attack the protective layer of the leather, the cleaned surfaces should be treated with BMW leather care agent. This also acts as an antistatic agent.
122nCaring for your vehicle
Airbags
To protect the leather from dampness or moisture, you can treat it with a BMW impregnating agent. We recommend that you perform this procedure twice a year on leather exposed to normal use. Spilled liquids should be wiped up immediately, and greasy and oily stains dabbed with a stain remover. If the upholstery is to be exposed to intense sunlight or if the vehicle is to be stored for an extended period, cover all leather surfaces (or, better yet, the windows) to prevent fading.
Use the cleaning and car-care products that you can obtain at
your BMW center.<
Cleaning agents can contain substances which are dangerous or which pose health risks. Therefore, always comply with the warnings and danger notices on the package. Open the doors or windows on your vehicle when cleaning the interior (when the roadster's convertible top is closed). Never clean your vehicle with solvents or other materials not specifi- cally intended for this application.<

Important safety notices
Do not attempt to remove the gas generators of the airbag restraint
system from the vehicle or to disas- semble them. Have inspection and service proce- dures performed by specially-trained personnel only. If the airbag restraint system malfunc- tions, is deactivated or triggered as a response to an accident, have the system repaired or disassembled by a BMW center only.
Do not make modifications of any kind to the individual components or system wiring. These include the upholstered covers on the steering wheel hub, in the instrument panel and in the side trim panels of the doors. Never apply adhe- sive materials to these components or cover or modify them in any way. Do not attempt to disassemble the steering wheel itself. To ensure compliance with applicable safety regulations, have the airbag generators disposed of by an BMW center only. Unprofessional attempts to service the system could lead to failure in an emer- gency or undesired airbag activation, either of which could result in personal injury.<

During storage Recharge the battery every six months. If it is not recharged, it will not be serviceable. Every time the battery is discharged, especially over extended periods, its service life is reduced.
Removing the vehicle from storage Recharge the battery if the "Magic Eye" turns black. Refer to page 141. Then have Inspection I performed by your BMW center, including a brake fluid replacement if necessary. Refer to the Service Manual.
Storing your vehicle
If you intend to store the vehicle for longer than three months, have the maintenance operations described on this page performed.<
5 Fill the fuel tank completely to
prevent the formation of condensa- tion.
6 Increase the tire inflation pressure to
51 psi (350 kPa).
Before parking the vehicle for storage 1 Dry the parking brake and footbrake by brake applications to prevent the brake discs and drums from corroding.
2 Park the vehicle in a covered, dry,
and well-ventilated room. Place the transmission in 1st gear. Chock the wheels to prevent the vehicle from rolling if necessary. Do not apply the parking brake.
3 Remove the battery, charge it
completely and store it in a cool (but frost-free) room.
M roadster: 4 Remove the hardtop* and store it
separately. Refer to page 97.
5 Close the convertible top.
Preparation for storage Have the following operations performed by your BMW center: 1 Clean and apply a rustproofing agent
or other treatment to the engine, engine compartment, undercarriage, axles and major components in accordance with approved repair procedures. Wash the vehicle, clean the interior and treat painted and chromed parts. Clean the rubber seals around the hood, luggage compartment and doors.
2 Change the engine oil and oil filter
with the engine at operating tempera- ture. As an additional corrosion protection measure, a corrosion inhibitor can be added to the engine in accordance with the manufac- turer's instructions.
3 Check the coolant level and concen-
tration and top up if necessary.
4 Check the fluid level of the wind-
shield washer fluid reservoir; top up if necessary.

California Proposition 65 Warning
California laws require us to state the following warning:
Engine exhaust, some of its constituents, and certain vehicle components contain or emit chemicals known to the State of California to cause cancer and birth defects or other reproductive harm.<
Any BMW center will be happy to advise you concerning the advisability, legal implications and factory recom- mendations for technical modifications to the vehicle. For this purpose, the BMW center will require the Vehicle Identification Number. The engine number is also required in some instances.
Light-Emitting Diodes (LEDs) Light-emitting diodes installed behind translucent lenses serve as the light source for many of the controls and displays in your vehicle. These LEDs are similar to laser technology.
Do not remove the protective lens and avoid staring directly at the unfiltered beam for extended periods (several hours), since inflammation of the iris could result.<

When the 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 subse- quently tightened, the indicator should go out within a few days.<
OBD connector
The connector for the Onboard Diag- nostic system (OBD) is located in the center console under a cover on the passenger's side (arrow). The purpose of the OBD system is to ensure proper operation of the emis- sion control system throughout the vehicle's lifetime by monitoring emis- sion-related components and systems for deterioration and malfunction.
An illuminated indicator informs you of the need for service, but not of the need to stop the vehicle. However, the systems should be checked by your BMW center at the earliest possible opportunity. 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 misfire over only a short period of time can seriously damage emission control components, especially the catalytic converter.

Changing a wheel
Repairing a flat tire
135n
The M roadster and M coupe are deliv- ered from the factory without a jack and lug wrench. Please have your BMW center switch the tires on your vehicle from summer to winter tires, or the reverse. To repair a flat tire, refer to the following pages.
M Mobility System You will find an M Mobility system in the M roadster and M coupe, for repairing flat tires. With the aid of this system, you can apply a liquid sealant to the inside of the tire, thereby sealing off the damaged area, and then continue driving. The M Mobility system makes trans- porting a spare wheel superfluous, thereby reducing the amount of weight you have to carry around.
Safety measures in the event of a flat tire:
Stop the vehicle as far as possible from the flow of traffic. Turn on the hazard warning flashers. Turn the steering wheel to the straight- ahead position and engage the steering lock, engage the parking brake and shift into 1st or reverse gear. All passengers should be outside the vehicle and well away from your imme- diate working area (for instance, behind the guardrail). If a warning triangle or portable hazard warning lamp is available, set it up on the roadside at an appropriate distance from the rear of the vehicle. Comply with all safety guidelines and regula- tions.<
