Drive at varying engine and road speeds, but do not exceed 4,500 rpm or 100 mph (160 km/h) during this time. Obey your local and state maximum speed limits. Refrain from using full throttle and avoid pressing the accelerator beyond the "kickdown" point. After you have driven 1,200 miles (2,000 km), you can gradually increase the engine and road speed. You should also comply with these break-in procedures if the engine or differential is replaced at a later point.
Tires Due to technical factors associated with their manufacture, tires do not achieve their full traction potential until an initial break-in period has elapsed. Thus, drive with extra care during the initial 200 miles (300 km). Obey your local and state maximum speed limits.
When the vehicle is operated on wet or slushy roads, a wedge of water may form between the tire and the road surface. This phenomenon is referred to as aquaplaning, or hydro- planing, and can lead to partial or com- plete loss of traction, vehicle control and braking effectiveness. Reduce your speed on wet roads.<
Brake system Brake pads and rotors do not achieve their optimum wear and surface-con- tact patterns until you have driven approx. 300 miles (500 km). To break in the separate parking brake drums, apply the parking brake lightly when coasting to a standstill (at a traffic signal, for instance), provided that traf- fic conditions allow you to do so. To avoid corrosion, repeat this proce- dure from time to time.
Driving notes
Catalytic converter
113n
Be sure to observe the instruc- tions above to prevent unburned
fuel from reaching the catalytic con- verter, otherwise, the catalytic con- verter could overheat and be damaged. High temperatures occur in every vehi- cle equipped with a catalytic converter. Heat shields are installed adjacent to some sections of the exhaust system. Never remove these shields; do not apply undercoating to their surfaces. When driving, standing at idle, and parking the vehicle, take extra care to avoid contact between the exhaust sys- tem and flammable materials (grass, hay, leaves, etc.). Such contact could lead to a fire, resulting in serious per- sonal injury and property damage.<
Brakes: Do not drive with your foot resting on the brake pedal. Even light but con- sistent pedal pressure can lead to high temperatures, brake wear, and possibly to brake failure. Aquaplaning: When driving on wet or slushy roads, reduce vehicle speed. If you do not, a wedge of water may form between the tires and the road surface. This phe- nomenon is referred to as aquaplaning or hydroplaning. It is characterized by a partial or complete loss of contact be- tween the tires and the road surface. The ultimate results are loss of steering and braking control. Driving through water: Do not drive through water over the road if it is deeper than 1 ft (30 cm), and then only at walking speed, otherwise the engine, electrical system and trans- mission could be damaged. Clothes hooks (when hardtop* is mounted): When suspending clothing from the hooks, ensure that they will not obstruct the driver's vision. Do not hang heavy objects on the hooks. If you do, they could cause personal injury during braking or evasive maneuvers.<
The catalytic converter reduces harmful exhaust emissions. It is designed for use with unleaded fuel only. Even minute quantities of lead would be enough to permanently damage both the catalytic converter and the system oxygen sensor. To ensure efficient, trouble-free engine operation and to avoid potential damage: > Be sure to comply with the scheduled
maintenance requirements
> Fill the fuel tank well before it is
empty
> Tow-start only when the engine is
cold. If you attempt to tow-start with a warm engine, unburned residual fuel in the catalytic converter could ignite and cause damage. It is better to jump-start the vehicle with outside assistance
> Avoid other situations in which the fuel is not burned, or burns incom- pletely, such as engaging the starter frequently or for extended periods, or repeated start attempts in which the engine does not start (stopping and restarting an engine which is running properly does not present a problem). Never allow the engine to run with any of the spark plug cables disconnected.
114nAntilock Brake System (ABS)
The concept ABS enhances active driving safety by helping to prevent the wheels from locking while braking. This is because locked wheels are dangerous. When the front wheels slide, the driver loses steering control over the vehicle. Traction loss at the rear wheels can cause the rear end to break into an uncontrolled skid. ABS is designed to meet two essential requirements during every brake appli- cation: > To help provide vehicle stability > To help maintain steering control and maneuverability – on all types of road surfaces (asphalt, concrete, mud, wet road surfaces, snow, ice).
The system can achieve the shortest braking distances possible under most conditions (on straight aways and in curves, on asphalt, ice, wet road sur- faces, etc.).
However, ABS continues to provide enhanced vehicle stability and steering response under these conditions.
Information for your safety Not even ABS can suspend the laws of physics. ABS cannot prevent the conse- quences of brake applications with inad- equate clearances for safety between vehicles, when exceeding the speed limit in curves, or the risks involved when aquaplaning occurs. Responsibil- ity for these types of situations remains in the hands (and at the feet) of the driver. You should never allow the added safety of ABS to lull you into a false sense of security, or mislead you into taking increased risks that could affect your own safety and that of others.
Do not make any modifications to the ABS system.
Service procedures on ABS are to be performed by authorized technicians only.<
Braking with ABS The system is operative once the vehi- cle exceeds a speed of approx. 6 mph (10 km/h). It is deactivated once again below approx. 4 mph (6 km/h). This means that the wheels can lock in the final phase of a panic stop – a factor of no significance in actual use. If you are in a situation that requires full braking, you will exploit the full benefits of the ABS system if you apply maxi- mum brake pressure ("panic stop"). Since the vehicle maintains steering responsiveness, you can nevertheless avoid possible obstacles with a mini- mum of steering effort. The ABS closed-loop control circuit cycles in fractions of a second. A pulsa- tion at the brake pedal, together with the sounds associated with the hydrau- lic controls, tells you that the brake sys- tem is within its maximum limit range, and reminds you that you should adapt road speed to the road conditions. On road surfaces that have a loose surface layer on a firm base with good traction (on gravel or snow, for exam- ple), or when snow chains are mounted, braking distances may be longer than with locked wheels.
Antilock Brake System (ABS)
Antilock Brake System (ABS)/ Cornering Brake Control (CBC) CBC is an advanced engineering de- sign of the ABS. When braking while cornering at high speed or braking dur- ing high lateral acceleration, or when braking during a lane change, vehicle stability is improved and steering re- sponse is enhanced.
In the event of a malfunction
If the ABS warning lamp in the instrument cluster lights up, refer to page 22. The brake system then reverts to conventional operation as on vehicles without ABS. However, have the brake system checked by your BMW center as soon as possible, to prevent undetected defects and cumulative faults from adversely affecting the brake system.
ABS warning lamp for Canadian models.
If the brake warning lamp comes on together with the indi- cator lamps for ABS and DSC – refer to page 21 – the entire ABS, CBC and DSC control sys- tem has failed. Continue driving cautiously and defensively. Avoid full brake applications. This could cause the vehicle to lose stability and you might no longer be able to control it. Have the system checked as soon as possible by your BMW center.

116nDisc brakes
Disc brakes furnish optimum decelera- tion and braking control and greater fade resistance under heavy use. When the vehicle is driven only occa- sionally, during extended periods when the vehicle is not used at all, and in operating conditions where brake appli- cations are less frequent, there is an increased tendency for corrosion of the rotors and accumulation of contamina- tion on the brake pads. This occurs because the minimal pressure that must be exerted by the pads to clean the rotors by brake applications is not reached. If the brake rotors are corroded, they will tend to respond to braking with a pulsating effect that even extended brake applications will fail to cure.
For your own safety: use only brake pads that BMW has ap-
proved for your particular vehicle model. BMW cannot evaluate non-ap- proved brake pads to determine if they are suited for use, and therefore cannot ensure the operating safety of the vehi- cle if they are installed.<
Driving notes When driving in wet conditions and in heavy rain, it is advisable to apply light pressure to the brake pedal every few miles or kilometers. Watch traffic condi- tions to ensure that this maneuver does not endanger other drivers. The heat which is generated by the brake appli- cations helps to dry the brake pads and rotors. Maximum braking force is obtained while the wheels continue to rotate, but rather when they are still barely turning immediately prior to locking. ABS main- tains this state automatically. If the ABS fails, you should revert to the staggered braking technique described on page 119. Extended or steep mountain descents do not necessarily lead to reduced braking efficiency if you drive downhill with the transmission in a gear that allows minimal brake applications (or, with automatic transmission*, in an appropriate lower gear). You can further increase the engine's braking effect by selecting a lower gear, downshifting as far as first gear or plac- ing the selector lever in position 1.
If engine braking should prove to be inadequate, you should still avoid ex- tended, continuous braking. Instead of maintaining low to moderate pressure over an extended period of time, you should decelerate by applying more substantial pressure to the brake pedal (watch for following traffic), releasing the pedal, and then repeating the appli- cation (staggered braking). The cooling phases between active braking inter- vals prevent the brakes from overheat- ing, thus ensuring that full braking capacity remains available at all times.
Do not coast with the clutch de- pressed or with the shift lever or
selector lever in "Neutral". Do not drive with the engine shut off. The engine provides no braking effect when the clutch is depressed or the transmission is in "Neutral", and there is no power assist for braking or steering when the engine is not running. Do not allow floor mats, carpets or any other objects to protrude into the area around the brake pedal, the clutch or the accelerator, which could obstruct their freedom of movement.<
Brake system
Brake fluid level
If the warning lamp for the brake system comes on with the park- ing brake released:
The brake fluid level is too low in the reservoir (refer to page 136). If the brake fluid level is too low and brake pedal travel has become notice- ably longer, there may be a defect in one of the hydraulic circuits of the brake system.
Warning lamps or the brake system for Canadian models.
Proceed to the nearest BMW center. Increased brake applica- tion pressure may be necessary under these conditions, and brake pedal travel may be significantly longer. Please remember to adapt your driving style accordingly.<
Brake linings
If the warning lamp for the brake pads lights up: The brake pads have reached
their minimum pad thickness. Proceed to the nearest BMW center as soon as possible to have the pads replaced.
For your own safety: use only BMW approved brake pads for your particular vehicle model. BMW cannot evaluate non-approved brake pads to determine if they are suited for use, and therefore cannot ensure the operating safety of the vehicle if they are installed.<
117n
118nWinter operation
Winter is often accompanied by rapid changes in weather, requiring not only a different driving style, but also certain preparations to the vehicle itself to en- sure that your vehicle operates safely and trouble free throughout the winter months.
Coolant Be sure that the coolant mixture con- tains the year-round ratio of 50:50 water and antifreeze/corrosion protec- tion. This mixture provides protection against freezing down to approx. –34 7 (–37 6). Replace the coolant every four years.
Locks BMW door lock deicer can be used to free them if frozen. This deicer also contains lubricant. After its use, treatment with BMW lock barrel grease is recommended.
Rubber seals and components To prevent the weather stripping from freezing, apply a spray-on rubber treat- ment or silicone spray to the door, hood and luggage compartment lid seals.
A full range of car care products is available from your BMW center.<
Snow chains BMW snow chains can be mounted on both summer and winter tires. Mount them in pairs on the rear wheels only and comply with the manufacturer's safety precautions. Do not exceed a maximum speed of 30 mph (50 km/h). In this type of exceptional situation where the snow chains are mounted, deactivate the DSC. Refer to page 88.
Starting off When starting off from a full stop in deep snow or when "rocking" the vehi- cle to free it, it may be effective to deactivate the DSC system for a short period. Refer to page 88.
Driving on low-traction road surfaces Use smooth, gentle pressure to control the accelerator pedal. Avoid excessive engine speeds and shift to the next higher gear at an early point. On down- hill grades or slopes, shift down to the next lower gear at an early point. Main- tain an adequate distance between yourself and the vehicle ahead.
119n
Do not shift down on slick road surfaces. Doing so could cause
the rear wheels to lose traction and skid, which could result in the loss of vehicle control.<
Depress the clutch during hard braking on road surfaces that pro-
vide only poor or uneven traction.<
Skid control Depress the clutch and release the ac- celerator pedal, or place the selector lever of the automatic transmission into the "Neutral" position. Countersteer carefully and attempt to regain control of the vehicle.
Parking Engage first or reverse gear. If your vehicle is equipped with an automatic transmission, place the selector lever in Park. On vehicles with manual trans- mission, also apply the parking brake when parking on inclined surfaces. In order to prevent the parking brake pads from locking due to frost or corrosion, dry them by gently applying the parking brake as the vehicle is coming to a stop. Make sure that following traffic is not endangered.
The brake lamps do not come on when the parking brake
is applied.<
Winter operation
Brakes Winter road conditions substantially reduce the amount of traction available between the tires and the road surface. Keep this in mind, because the braking distance increases substantially. ABS is intended to prevent the wheels from locking during brake applications, thus helping to maintain vehicle stability and steering response. If the ABS does not respond in a critical braking situation and the wheels lock, reduce the pressure on the brake pedal until the wheels just start to roll again while still maintaining enough force to continue braking. Then increase the pressure, reduce the pressure when the wheels lock, reapply pressure, etc. This staggered braking procedure will reduce stopping distances while help- ing you maintain steering control. You can then attempt to steer around hazards after you have reduced pres- sure on the brake pedal.
120nPower steering
Cellular phone*
Radio reception
Changes in steering response, e.g. high steering effort: Consult a BMW center to have the sys- tem checked.
If the power steering fails, in- creased effort will be required to
steer the vehicle.<
Only mobile communications systems (cellular phone, two-way radios, etc.) with an output up to 10 watts are per- mitted. Mobile communications devices not specifically designed for use in your vehicle may trigger malfunctions while operating your vehicle. BMW can nei- ther test nor assume responsibility for every individual product being offered on the market. We recommend that you consult your BMW center before pur- chasing any device of this kind. To ensure that your BMW continues to provide reliable and trouble-free opera- tion, do not use a cellular phone or other radio device with an antenna located inside the passenger compart- ment. The antenna should always be mounted on the outside of the vehicle.
Before loading the vehicle on a car-carrier train or driving it
through a car-wash, remove the antenna.<
The reception and sound quality obtained from mobile radios varies according to a variety of factors, includ- ing the broadcast range of the transmit- ter and the directional orientation of the antenna. Interference factors such as high-tension power lines, structural or natural obstructions can all lead to un- avoidable reception interference, re- gardless of how well the vehicle sound system is operating. Climatic factors such as intense solar radiation, fog, rain and snow can also interfere with reception. Car telephones or cellular phones not approved by BMW can also cause in- terference in the radio during a tele- phone call. This phenomenon assumes the form of a low-pitched hum emanat- ing from the speaker system. Please refer to the supplementary Owner's Manual provided with your car radio* for detailed information on its use.
Hardtop*
It is not necessary to remove the fabric top even in the winter, when the hard- top is generally in constant use. But you can take it off at any time with no prob- lem. Before the fabric top is stored in the convertible top compartment, it must be absolutely dry in order to keep water and mildew from forming. The hardtop offers reading lamps as well as clothes hooks in the rear, which can be used simply by pressing on them. In addition, a luggage rack sys- tem can also be mounted on the hard- top. If you have a problem in this re- gard, please contact your BMW center.
When suspending clothing from the hooks, ensure that they will
not obstruct the driver's vision. Do not hang heavy objects on the hooks. If you do so, they could cause personal injury during braking or evasive maneuvers.<
Two persons are required for installing or removing the hardtop. Work with extreme caution in order to avoid paint damage and damage to the body or hardtop. To facilitate the installation or removal of the hardtop, you can purchase either a specially designed hardtop lift* or hard- top roller carrier* at your BMW center.
Storage
Storing the hardtop on the floor: Push the provided hard foam block toward the front in the center onto the hardtop. The arrow on the foam block has to point upward.<
121n
Installation 1 Lower the side windows completely and fold down the sun visors. If nec- essary, remove the antenna rod to prevent damage
2 For vehicles with manual convertible top operation, unlock the convertible top compartment lid and, if neces- sary, open it somewhat. For vehicles with fully automatic convertible top operation*, start opening the con- vertible top compartment lid by pressing the button for the convert- ible top operation
3 Remove the trim pieces on both sides by pulling them toward the back (arrow) and close the convert- ible top compartment lid again
9 To lock the hardtop in front, keep
closing the front locking levers until you hear them engage.
Raise the hardtop carefully. Be very careful not to displace the
seals. Seals that have been accidentally displaced or pulled out lead to leaks.c
Removing Remove the hardtop in the opposite order of installation.

Tire inflation pressure
Tire condition
123n
Information for your safety The factory approved radial tires are matched to the vehicle and have been selected to provide optimum safety and driving comfort. It is not merely the tire's service life, but also driving comfort and – above all else – driving safety that depend on the con- dition of the tires and the maintenance of the specified tire pressure. Incorrect inflation pressure is a frequent cause of tire damage. It also signifi- cantly influences the roadholding ability of your BMW.
Check tire inflation pressures reg- ularly – including the space-saver spare tire – at least twice a month and before beginning a longer trip (see page 27). If this is not done, incorrect tire pressures can cause driving insta- bility and tire damage, ultimately result- ing in accidents.<
Tire tread – tire damage Inspect your tires frequently for tread wear, signs of damage and for foreign objects lodged in the tread. Check the tread depth. Tread depth should not be allowed to go below 0.12 in (3 mm), even though the legally specified minimum tread depth is only 0.063 in (1.6 mm). At a tread depth of 0.063 in (1.6 mm), tread depth indicators (arrow) in the tread- groove base indicate that the legally- permissible wear limit has been reached. Below 0.12 in (3 mm) tread depth, there is an increased risk of aquaplaning, even at relatively moder- ate speeds and with only small amounts of water on the road.
Do not drive on a deflated (flat) tire. A flat tire greatly impairs
steering and braking response, and can lead to complete loss of control over the vehicle. Avoid overloading the vehicle so that the permitted load on the tires is not ex- ceeded. Overloading can lead to over- heating and increases the rate at which damage develops inside the tires. You could have a blowout as a result. Unusual vibrations encountered during normal vehicle operation can indicate tire failure or some other vehicle defect. This is also true for irregularities in the vehicle's handling characteristics, such as a pronounced tendency to pull to the left or right. Should this occur, respond by immediately reducing your speed. Proceed carefully to the nearest BMW center or professional tire center, or have the vehicle towed in to have it and its tires inspected. Tire damage (up to and including sud- den and complete air loss) can endan- ger the lives of both the vehicle occu- pants and other drivers on the road.<
124n
Tire replacement
To maintain good handling and vehicle response, use only tires of a single tread configuration from a single manu- facturer. BMW tests and approves wheel/tire combinations. Refer to page 128.
DOT Quality Grades Treadwear Traction AA A B C Temperature A B C
In addition to the tire grades listed above, all passenger car tires must
conform to Federal Safety Require- ments as well.<
Treadwear The treadwear grade is a comparative rating based on the wear rate of the tire when tested under controlled condi- tions on a specified government test course. For example, a tire graded 150 would wear one and one-half (1-1/2) times as well on the government course as a tire graded 100. The relative performance of tires depends upon the actual condi- tions of their use, however, and may depart significantly from the norm due to variations in driving habits, service
practices and differences in road characteristics 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 speci- fied government test surfaces of as- phalt 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, corner- ing, hydroplaning, or peak traction characteristics.<
Temperature The temperature grades are A (the high- est), B, and C, representing the tire's re- sistance to the generation of heat and its ability to dissipate heat when tested under controlled conditions on a speci- fied indoor laboratory test wheel. Sustained high temperature can cause the tire material to degenerate and re- duce tire life, and excessive tempera- ture can lead to sudden tire failure. The
Grade C corresponds to a level of per- formance which all passenger car tires must meet under the Federal Motor Vehicle 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 prop- erly inflated and not overloaded. Exces- sive speed, underinflation, or excessive loading, either separately or in combina- tion, can cause heat buildup and possi- ble tire failure.<
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
Do not use retreaded tires ("caps"). Driving safety may be impaired by their use. This due to the possible varia- tions in casing structures and, in some cases, to their extreme age, factors which can lead to a decrease in their durability.<
Tire replacement
Tire rotation
125n
If different tire sizes are mounted on the front and rear axles (refer to page 128), the wheels may not be rotated from one axle to the other.<
Tire age The date on which the tire was manu- factured is indicated by the code on the sidewall: DOT ... 150 indicates that the tire was manufactured during week 15 of the year 2000. BMW recommends the replacement of all tires when the tires are no more than 6 years old, even if a tire life of 10 years is possible. Spare tires over 6 years old should be used only in case of emergency. A tire in this condition should be replaced by a new tire immediately, and should not be mounted together with new tires.
Between the axles The tread wear patterns at the front end differ from those at the rear – the actual patterns will vary according to individual driving conditions. In the interests of safety and maintaining opti- mal handling characteristics, tire rota- tion is not recommended. If a proposed interaxle rotation of tires is based on economic considerations, one should consider whether the costs for the rotation are likely to be recap- tured by any increase in the service life of the tires that might be realized. Rota- tion should always be carried out at short intervals, with a maximum of 3,000 miles (5,000 km). Consult your BMW center for more information. Should you decide to rotate the tires, it is essential to comply with the following: Rotate tires on the same side only, since braking characteristics and road grip could otherwise be adversely affected. Following rotation, the tire inflation pressure should always be corrected.
126nWheel and tire combinations
The right choice Use only tires approved by BMW. Refer to the information beginning on page 128. Due to the high speeds this vehicle can reach, the use of specific brands, spec- ifications and sizes is mandatory. Con- sult any BMW center for details. Comply with local/national regulations.
The correct wheel-tire combina- tion affects different systems, e.g.
ABS, ATC* and DSC, whose function would otherwise be impaired if im- proper wheel-tire combinations are used. For this reason, use only tires of the same brand and tread pattern. In the event of a flat tire, for example, remount the approved wheel-tire combination as soon as possible.<
225/50 R 16 92 W
Codes on tires and wheels The tire codes will aid you in selecting the correct tire. The codes on radial tires: For example: Nominal width in mm Aspect ratio in X Radial tire code Rim diameter in inches Load rating (not on ZR tires) Speed rating (before R on ZR tires)
The speed rating indicates the ap- proved maximum speed for the tire. Summer tires: S = up to 112 mph (180 km/h) = up to 118 mph (190 km/h) H = up to 130 mph (210 km/h) V = up to 150 mph (240 km/h) W = up to 167 mph (270 km/h) Y = over 167 mph (270 km/h) ZR = over 150 mph (240 km/h)
Winter tires: Q M+S = up to 100 mph (160 km/h) T M+S = up to 118 mph (190 km/h) H M+S = up to 130 mph (210 km/h) Codes stamped on light-alloy wheels: For example: Rim width in inches Code letter for flange type Symbol for full-drop center rim Rim diameter in inches Hump on the 2 rim shoulders
x 16 H 2
Protect tire valves from dirt by using screw-on valve stem caps. Dirt in the valves frequently leads to slow leaks.
127n
Storage Always store tires in a cool, dry place. Store them away from light whenever possible. Protect the tires against con- tact with oil, grease and fuel.
Snow chains* The use of narrow-link BMW snow chains on summer or winter tires is approved only in pairs and only on the rear wheels. Comply with all manufac- turer's safety precautions when mount- ing the chains.
Winter tires
Choosing the right tire BMW recommends winter tires (M+S radial tires) for driving in adverse winter road conditions. Although all-season tires with the M+S identification provide better winter traction than summer tires with H, V, W Y and ZR speed ratings, they generally fail to provide the same levels of performance as standard winter tires. In the interests of safe tracking and steering response, install winter tires made by the same manufacturer having the same tread configuration on all four wheels. Mount only winter tires which have been approved by BMW. Any BMW center will be glad to provide you with information on the best winter tires for your particular driving conditions.
Do not exceed specified maximum speeds
Never exceed the maximum speed for which winter tires are rated.
Unprofessional attempts by laymen to service tires can lead to damage and accidents. Have this work performed by skilled professionals only. Any BMW center has the required technical knowledge and the proper equipment and will be happy to assist you.<
Tire condition, tire pressure Once the tire wears to a tread depth below 0.16 in (4 mm), winter tires dis- play a perceptible decrease in their ability to cope with winter driving condi- tions, and should be replaced in the interest of safety. Comply with the specified tire inflation pressures – and be sure to have the wheel and tire assemblies balanced every time you change the tires.

Headlamp* and windshield washer system Capacity: approx. 5.6 US quarts (5.3 liters). Fill with water and – if required – with a washer antifreeze (according to manu- facturer's recommendations).
We recommend that you mix the washer fluid before adding it to
the reservoir.<
Engine oil
133n
Checking the oil level 1 Park the vehicle on a level surface 2 Shut the engine off after it has
reached normal operating tempera- ture
3 After approx. 5 minutes, pull the dip- stick out 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
5 The oil level should be between the
two marks on the dipstick.
As with fuel economy, oil consumption is directly influenced by your driving style and vehicle operating conditions.
When the oil is between the two marks on the dipstick, there is approx. 1.1 US quarts (1 liter). Do not fill be- yond the upper mark on the dipstick. Excess oil will damage the engine.
To add oil Wait until the level has dropped to just above the lower mark before adding oil. However, never let the oil drop below the lower mark.
BMW engines are designed to op- erate without oil additives; the use
of additives could lead to damage in some cases. This also applies to the manual transmission, the automatic transmission*, the differential, and power steering system.<
Viscosity ratings Viscosity is the oil flow rating as estab- lished in SAE classes. The selection of the correct SAE class depends on the climatic conditions in the area where you drive your BMW.
Approved oils are in SAE classes 5W-40 and 5W-30.<
These kinds of oil may be used for driving in all outdoor temperatures.
134nEngine oil
Specified engine oils The quality of the engine oil is extremely important for the function and life of an engine. Based on extensive testing, BMW has approved only certain types of engine oils. Use only approved "BMW High Perfor- mance Synthetic Oil". If you are unable to obtain "BMW High Performance Synthetic Oil", you may use small volumes of other approved synthetic oils for topping off between oil changes. Use only oils with the specifi- cation API SH or higher.
Ask your BMW center for details concerning the specific "BMW
High Performance Synthetic Oil" or syn- thetic oils that have been approved.<

Engine oil
Coolant
135n
Always comply with all environ- mental protection guidelines and
regulations when disposing of used oil.<
Recommendation: have the oil changed by your BMW center only.
Continuous exposure to used oil has caused cancer in laboratory
testing. For this reason, thoroughly wash any areas of skin that come into contact with oil using soap and water. Always store oils, grease and similar materials so that they are inaccessible to children. Comply with warning labels and information on containers.<
Do not add coolant to the cooling system when the engine is hot. If
you do, escaping coolant can cause burns. To avoid the possibility of damage later on, never use anything other than fac- tory approved nitrite and amino-free extended-duty antifreeze with corrosion inhibitor. Your BMW center is familiar with the factory specifications. Antifreeze and anticorrosion agents are hazardous to health. You should always store them in their original container and in a location that is inaccessible to children. Extended duty antifreeze with corrosion inhibitor contains ethylene glycol, a flammable substance. There- fore, do not spill antifreeze with corro- sion inhibitor on hot engine parts. It could ignite and cause serious burns.<
Comply with the applicable envi- ronmental laws regulating the dis- posal of extended-duty antifreeze with corrosion inhibitor.<
Checking coolant level Correct coolant level when the engine is cold (approx. 68 7 or +20 6): Unscrew the cap from the expansion tank. The coolant level is correct when the upper end of the red float is at least even with the upper edge of the filler neck (refer to the arrow in the illustra- tion), but no more than 0.8 inches (2 cm) above it – that is, up to the second mark on the float (refer also to the schematic diagram next to the filler neck).
136nCoolant
Brake fluid
Adding coolant Wait until the engine cools before re- moving the cap from the expansion tank. The coolant gauge needle in the instrument cluster must be located in the blue zone. If it is not, there is a danger of scalding. 1 Turn the cap slightly counterclock- wise in order to allow accumulated pressure to escape. Then open the cap
2 If the coolant is low, slowly add coolant until the correct level is reached – do not overfill.
The coolant is a mixture of water and extended-duty antifreeze with corrosion inhibitor. Always maintain the pre- scribed all-season 50:50 mixture ratio for year-round protection against inter- nal corrosion. No other additives are required. Replace the coolant every four years.
If the warning lamp for the brake sys- tem comes on and the parking brake has been released: Check the brake fluid level. Fill it to the top mark ("MAX") if necessary. For adding brake fluid or for determin- ing and correcting the cause of brake fluid loss, consult your BMW center. Your BMW center is familiar with the specifications for factory-approved brake fluids (DOT 4). Brake fluid loss can result in extended pedal travel. Comply with the informa- tion provided on page 117.
Brake fluid is hygroscopic, that is, it absorbs moisture from the air
over time. In order to ensure the safety and reli- ability of the brake system, have the brake fluid changed every two years by a BMW center. Refer also to the Service and Warranty Information Booklet (US models) or the Warranty and Service Guide Booklet (Canadian models). Brake fluid is toxic and damages the vehicle's paint. You should always store it in its original container and in a loca- tion inaccessible to children. Do not spill the fluid and do not fill the brake fluid reservoir beyond the "MAX" mark. The brake fluid could ignite upon contact with hot engine parts and cause serious burns.<
Comply with the applicable envi- ronmental laws regulating the dis-
posal of brake fluid.<

The BMW Maintenance System
Service Interval Display. While conven- tional systems rely on distance traveled alone to determine when service is due, the BMW Maintenance System has for years considered the actual conditions under which the vehicle operates, be- cause miles can be traveled in many different ways: From a maintenance point of view, 62,000 miles (100,000 km) of short-dis- tance urban driving are not the same as 62,000 miles (100,000 km) of long-dis- tance highway driving. In response to this fact, the BMW Main- tenance System monitors operating conditions as the basis for determining the optimum service intervals for your individual vehicle. The BMW Mainte- nance System includes the Engine Oil Service and Inspections I and II. Determining maintenance intervals ac- cording to the actual use of the vehicle covers every kind of operating situation. Even those who drive very little – signif- icantly less than 6,000 miles (10,000 km) annually – should still have the engine oil changed at least every 2 years because engine oil deteriorates over time, re- gardless of the amount of wear and tear to which it has been subjected.
Service and Warranty Information Booklet (US models)/Warranty and Service Guide (Canadian models) For additional information on mainte- nance intervals and procedures, please refer to the Service and Warranty Infor- mation Booklet (US models) or to the Warranty and Service Guide (Canadian models). As a precaution against rust, it is advis- able to have the body checked for dam- age from rocks or gravel at the same time, depending upon operating condi- tions.
Have your BMW center perform maintenance and repair.
Your BMW center is always up-to-date on the latest maintenance work and re- pair techniques and 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 (Canadian models). These entries will constitute your proof that the vehicle has received regular maintenance. They are also required for warranty claims.<
