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. Cornering Brake Control (CBC) CBC is an advanced engineering devel-
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.

model.
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.

Winter operationBrakingWinter 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 braking distances while helping
you maintain steering control.
You can then attempt to steer around
hazards after you have reduced pres-
sure on the brake pedal.Do not shift down on slick road
surfaces Ð if you want to decel-
erate. 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
provide only poor or uneven traction.<
Skid control Depress the clutch and release the
accelerator pedal, or place the selector
lever of the automatic transmission into
the "Neutral" position. Countersteer
carefully and attempt to regain control
of the vehicle.
ParkingEngage 1st 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.<

Power steering Cellular phone
*
Radio reception
Changes in steering response, e. g. high
steering effort:
Consult a BMW center to have the
system checked.
If the power steering fails,
increased effort will be required to
steer the vehicle.<
Only mobile communications systems
(cellular phone, radio, etc.) with an
output up to 10 watts are permitted.
Mobile communications devices not
specifically designed for use in your
vehicle may trigger malfunctions while
operating your vehicle. BMW can
neither test nor assume responsibility
for every individual product being
offered on the market. We recommend
that you consult your BMW center
before purchasing 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 vary
according to a variety of factors,
including the broadcast range of the
transmitter and the directional orienta-
tion of the antenna. Interference factors
such as high-tension power lines,
structural or natural obstructions can all
lead to unavoidable reception interfer-
ence, regardless 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.
Cellular or portable phones not recom-
mended by BMW can also generate
interference in the radio when making
telephone calls. This phenomenon
assumes the form of a low-pitched hum
emanating from the speaker system.
Please refer to the Owner's Manual
provided with your sound system for
detailed information on its use.

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.<

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.

Engine oilChecking 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
dipstick 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.462de244
The oil volume between the two marks
on the dipstick corresponds to approx.
1.1 US quarts (1 liter). Do not fill beyond
the upper mark on the dipstick. Excess
oil will damage the engine.460de189
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
operate without oil additives; the
use of additives could lead to damage
in some cases. This also applies to the
manual transmission, automatic trans-
mission, differential and power steering
system.<462de245

Modifications may not be made on
either the wiring or the individual
components in the airbag system.
These include the padded steering
wheel hub, the instrument panel, the
side trim panels of the front or rear
doors and the roof pillars or the sides
of the headliner. Do not apply adhesive
materials to these components, cover
or modify them in any way. Do not
attempt to remove or dismantle the
steering wheel.
To ensure compliance with official
safety regulations, entrust disposal of
airbag generators to a BMW center.
Unprofessional attempts to service
the system could lead to failure in an
emergency or undesired airbag activa-
tion, either of which could result in
personal injury. special procedures if you intend

Changing a wheel
Take these precautionary mea-
sures if you have either a flat tire or
are changing a wheel.
Stop the vehicle as far as possible from
passing traffic. Park on a firm, flat
surface. Switch on the hazard warning
flashers. Turn the steering wheel to the
straight-ahead position, remove the key
and engage the steering lock. Shift into
1st gear or reverse (selector lever in
"Park" with automatic transmission)
and engage the parking brake.
All passengers should be outside the
vehicle and well away from your imme-
diate working area (behind a guardrail,
for instance).
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 regulations.
Change the wheel only on a level, firm
surface that is not slippery. Avoid jack-
ing the vehicle on a soft or slippery
support surface (snow, ice, loose gravel,
etc.), as it could slide sideways.
Position the jack on a firm support
surface.
Do not place wooden blocks or similar
objects under the jack, otherwise, the
jack might not be able to reach its full
support capacity because of the limited
height.
Do not lie under the vehicle or start the
engine when the vehicle is supported by
the jack. Failure to comply with this
creates a risk of fatal injury.<
Your BMW has either a spare tire or
space-saver tire for temporary use to
ensure your mobility.
To remove the spare wheel, lift out
the floor panel in the luggage
compartment completely (refer to
page 109.<
What you will needIn order to avoid rattling noises later,
note the position of the tools when you
remove them and return them to their
original position when you are through
using them.
>Jack (1)
Raise both the floor panel and spare
tire panel and loosen the red wing nut
(arrow).
When you have completed your work,
screw the jack all the way back
down. Fold the handle back and
insert it into its holder
