To ensure maximum economy and a 
long service life, we request that you 
observe the following suggestions.
Engine and differentialUp to 1,200 miles (2,000 km):
Drive at varying engine speeds and road 
speeds, but do not exceed the following 
engine or road speeds during this time: 
4,500 rpm or 100 mph (160 km/h).
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 speeds.
You should also comply with these 
break-in procedures if the engine or 
differential is replaced at a later point.
TiresDue 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 hydropla-
ning, and can lead to partial or 
complete loss of traction, vehicle 
control and braking effectiveness. 
Reduce your speed on wet roads.<
Brake systemAfter approximately 300 miles (500 km), 
the brake pads and discs achieve the 
optimal pad surface and wear patterns 
required for trouble-free operation and 
long service life.
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 
traffic conditions allow you to do so.
To avoid corrosion, repeat this proce-
dure from time to time.
The brake lamps do not come on 
when the parking brake is applied.
Vacuum for the brake system servo unit 
on your BMW is available only when the 
engine is running. When you move the 
vehicle with the engine off Ð when 
towing, for example Ð substantially 
higher levels of pedal force will be 
required to brake the vehicle.
(500 km). Engage the gears carefully 
during the break-in period.

Antilock Brake System (ABS)Nevertheless, ABS possesses the 
advantage of vehicle stability and 
steering response.Information for your safetyNot even ABS can suspend the laws 
of physics. The consequences of brake 
applications with inadequate clea-
rances for safety between vehicles, 
excessive speed or if aquaplaning 
occurs are always the responsibility 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 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.
opment of ABS. When braking while 
cornering at high speed or braking 
during high lateral acceleration, or 
when braking during a lane change, 
vehicle stability is improved and 
steering response 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, 
refer any problems to your authorized 
BMW center at the earliest opportunity.
ABS warning lamp for Canadian

If the brake warning lamps light 
up together with the indicator 
lamps for ABS and ASC+T/DSC 
Ð refer to page 19 Ð then the 
entire regulating system, the  
ABS, CBC and ASC+T/DSC
 and 
ADB/ ADB-X/DBC have failed. 
Continue driving cautiously and 
defensively. Avoid full brake applica-
tions. This could cause the vehicle to 
lose stability and you might no longer 
be able to control it.
Have the system checked by your BMW 
center as soon as possible.

Information for your safetyThe factory-approved radial tires are 
matched to the vehicle and have been 
selected to provide optimum safety and 
driving comfort on your vehicle. 
It is not merely the tire's service life, but 
also driving comfort and Ð above all 
else Ð driving safety that depend on the 
condition of the tires and the mainte-
nance 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 the tire inflation pressure Ð 
for the space-saver spare tire or 
spare tire Ð on a regular basis (refer to 
page 28), at least twice a month, and 
before starting out on any extended 
trip. If this is not done, incorrect tire 
pressures can cause driving instability 
and tire damage, ultimately resulting in 
an accident.<
Tire tread Ð tire damageInspect 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 wear 
limit Ð applicable by law throughout 
Europe Ð has been reached. Below 
0.12 in (3 mm) tread depth, there is an 
increased risk of aquaplaning, even at 
relatively moderate speeds and with 
only small amounts of water on the 
road.390de331
Never continue driving 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 
exceeded. Overloading can lead to 
overheating 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. 
The same applies to irregularities 
related to your usual driving style, such 
as pulling hard to the left or right. 
Should this occur, respond by immedi-
ately 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 
sudden and complete air loss) can 
endanger the lives of both the vehicle 
occupants and other road users.<

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 129.DOT Quality GradesTreadwear 
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 wearThe tread wear 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 (1g) 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 char-
acteristics and climate.
TractionThe 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 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, cornering, 
hydroplaning, or peak traction charac-
teristics.< TemperatureThe 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 condi-
tions 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 Vehicle Safety Stan-
dard No. 109. Grades B and A repre-
sent 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, under-inflation, or 
excessive loading, either separately or 
in combination, can cause heat buildup 
and possible 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. Driving 
safety may be impaired by their 
use. This is due to the possible varia-
tions in casing structures and, in some 
cases, to their extreme age, which can 
lead to a decrease in their durability.<
Tire replacement 

126n
Tire replacement Tire rotationTire ageThe date on which the tire was manu-
factured is indicated by the code on the 
sidewall:
DOT ... 4100 indicates that the tire was 
manufactured during week 41 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 
of this age should be replaced by a new 
tire immediately, and should not be 
mounted together with new tires.
Between the axlesThe tread wear patterns at the front end 
differ from those at the rear Ð the actual 
patterns will vary according to indi-
vidual driving conditions. In the inter-
ests of safety and maintaining optimal 
handling characteristics, tire rotation 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. In 
principle, interaxle rotation must be 
performed in 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.If different tire sizes are mounted 
on the front and rear axles (refer to 
page 12 9), the wheels may not be 
rotated from one axle to the other.< 

128n
Winter tiresChoosing the right tireBMW recommends winter tires (M+S 
radial tires) for driving in adverse winter 
road conditions. So-called all-season 
tires with the M+S-identification mark 
do indeed possess better winter trac-
tion than summer tires with the load 
rating H, V, W, Y und ZR, but usually do 
not achieve the same level of perfor-
mance as winter tires. 
In the interests of safe tracking and 
steering response, install radial tires 
made by the same manufacturer and 
with the same tread configuration on all 
four wheels if you elect to mount winter 
tires.
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 the 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 pressureOnce the tire wears to below 0.16 in 
(4 mm), winter tires display a percep-
tible decrease in their ability to cope 
with winter driving conditions, and 
should be replaced in the interest of 
safety.
Comply with the specified tire inflation 
pressures Ð and be sure to have the 
wheel and tire assemblies balanced 
every time you change the tires.
StorageAlways store tires in a cool, dry place. 
Store them away from light whenever 
possible. Protect the tires against 
contact 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 
mounting the chains.
BMW 325xi: in a worst-case scenario, 
i.e. if your vehicle is stuck on one side 
or you cannot access one tire, then only 
one chain may be attached to a rear 
wheel for a short period of time.
Comply with all manufacturer's safety 
precautions when mounting the chains.

Coolant Brake fluidAdding coolant Wait until the engine cools before 
removing the cap from the expansion 
tank. The needle of the coolant gauge 
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. 
2 If the coolant is low, slowly add 
coolant until the correct level is 
reached Ð do not overfill.
The coolant is a mixture of water and 
extended-duty antifreeze with corrosion 
inhibitor. Always maintain the 
prescribed all-season 50:50 mixture 
ratio for year-round protection against 
internal corrosion. No other additives 
are required.
Replace the coolant every four years.If the brake warning lamp 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 deter-
mining 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 120.
460de128
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 
disposal of brake fluid.<

The BMW Maintenance System has 
been designed as a reliable means for 
providing maximum driving and operat-
ing safety Ð and as cost effectively as 
possible for you. 
Please keep in mind that regular main-
tenance is not only necessary for the 
safety of your vehicle, but also plays a 
significant role in maintaining the resale 
value of the vehicle. 
Service Interval DisplayAdvanced technology is employed 
to calculate the optimal maintenance 
intervals. These are then indicated in 
the Service Interval Display. While 
conventional systems rely on distance 
traveled alone to determine when 
service is due, the BMW Maintenance 
System has for years considered the 460us112
actual conditions under which the 
vehicle operates, because miles can be 
traveled in many different ways:
From a maintenance perspective, 
62,000 miles (100,000 km) of short-
distance urban driving are not equiva-
lent to 62,000 miles (100,000 km) 
covered at moderate speeds in long-
distance highway travel.
The BMW Maintenance System 
includes the Engine Oil Service and 
Inspections I and II.
Determining the maintenance intervals 
according to the actual use of the vehi-
cle covers every kind of operating situa-
tion. However, even those who drive 
only short distances Ð significantly less 
than 6,000 miles (10,000 km) annually Ð 
should have the engine oil changed at 
least every 2 years since oil deterio-
rates over time, regardless of use.

Service Guide (Canada 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 
advisable to have the body checked for 
damage from rocks or gravel at the 
same time, depending upon operating 
conditions.
Have your BMW center perform 
maintenance and repair.
Your BMW center is always "up to date" 
on the latest maintenance work and 
repair 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.<
