Alarm system
*
The conceptThe vehicle alarm system responds:
>When a door, the hood or the tailgate
is opened.
>To movement inside the vehicle
(interior motion sensor).
>To a change of the vehicle's tilt Ð if
someone attempts to steal the wheels
or tow the vehicle without authoriza-
tion, for example.
>To interruption of battery voltage.
The system responds to unauthorized
vehicle entry and attempted theft by
simultaneously activating the following:
>Sounding an acoustical alarm for
30 seconds.
>Activating the hazard warning flashers
for approx. five minutes.
>Flashing the high beams flash on and
off in rhythm with the hazard warning
flashers.
To activate and deactivate the
alarm systemWhen the vehicle is locked or unlocked
by using a key or the remote control,
the alarm system is also armed or
disarmed at the same time.
The interior motion sensor and tilt alarm
sensor are activated 30 seconds after
the last locking operation.
If the alarm system has been armed
correctly, the hazard warning flashers
flash once.
You can have one signal set as
acknowledgment when arming
and disarming.<
You can also open the rear window
when the system is armed by pressing
button 3 of the remote control (refer to
page 37). When it is closed, the rear
window is once again secured.
Indicator lamp displaysThe indicator lamp is located under the
inside rearview mirror.
>The indicator lamp flashes
continuously: the system is armed.
>The indicator lamp flashes when it
is armed: doors, the hood, tailgate
or rear window have not been prop-
erly closed. Even if you do not close
the alerted area, the remaining areas
are deadlocked, and the indicator
lamp flashes continuously after
10 seconds. However, the interior
motion sensor is not activated.
>The indicator lamp goes out when the
system is disarmed: no manipulation
or attempted intrusions have been
detected in the period since the
system was armed.463us010

Mirrors Car Memory, Key Memory Interior rearview mirror with
automatic dimming feature
*
By responding to the effects of ambient
light and the glare from following traffic,
this mirror automatically dims through
an infinitely-variable range.
The mirror switches to its clear,
undimmed mode whenever the trans-
mission is placed in reverse gear
(selector lever in "Reverse").
For proper functioning of the mirror, be
sure that the two photocells are unob-
structed and clean. One of the photo-
cells (arrow) is positioned in the mirror's
glass, while the other is slightly offset
on the opposite side of the mirror.
For an explanation of the electro-
chromic technology used in this mirror,
refer to page 176.460de020
How the system functionsYou have probably frequently wished
that you could configure individual
functions of your vehicles to reflect your
own personal requirements. In engi-
neering your vehicle, BMW has
included several user-defined func-
tions in the vehicle's design. Your BMW
center can make these settings for you
in accordance with your wishes.
There are settings related to the vehicle
("Car Memory") and settings related to
individuals ("Key Memory"). You can
have up to four different basic settings
adjusted for four different persons. The
only requirement is that each person
uses his or her own remote control key.
When your vehicle is unlocked with the
remote control, the vehicle recognizes
the individual user by means of a data
exchange with the key, and makes 463de029
adjustments accordingly.
So that you can distinguish among the
different keys, colored decals are
supplied along with the keys.What the system can doYour authorized BMW center can
provide you with details on the capabili-
ties of the Car Memory and Key
Memory systems. A few examples
follow below:
Examples for Car Memory:
>Various signals used as acknowl-
edgement when locking or unlocking
your vehicle.
>Deactivating/activating the Follow-
Me-Home lamps function.
>Activating/deactivating daytime
running lamps
*.
Examples for Key Memory:
>Automatically setting the driver's
power seat.
>Locking your vehicle after starting off.
When unlocking your vehicle, first
unlock the driver's door, then the rest of
the vehicle.
You will see this symbol through-
out the Owner's Manual. It is to
remind you at appropriate places of the
settings that are available to you.<

Winter operationWinter is often accompanied by rapid
changes in weather. Adaptions in
driving style should be accompanied by
preparations on the vehicle itself to
ensure that your vehicle operates safely
and trouble-free throughout the winter
months.CoolantBe sure that the coolant mixture
contains the year-round ratio of 50:50
water and antifreeze/corrosion protec-
tion. This mixture will resist freezing to
approx. Ð34 7 (Ð37 6). Replace the
coolant every four years.LocksBMW door lock deicer can be used to
free them if frozen. This deicer also
contains lubricant.
After using the deicer, treatment with
BMW lock cylinder grease is recom-
mended.
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 tailgate seals.
A full range of car care products is
available from your BMW center.
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 ASC+T/DSC. Refer to
page 79.
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.
Starting offWhen starting off from a full stop in
deep snow or when "rocking" the
vehicle to free it, it may be effective to
deactivate the ASC+T/DSC system for
a short period. Refer to page 79.Driving on low-traction road
surfacesUse smooth, gentle pressure to control
the accelerator pedal. Avoid excessive
engine speeds and shift to the next
higher gear at an early point. Downshift
into the next lower gear on ascents or
descents. Maintain an adequate
distance between yourself and the
vehicle ahead.

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 and Warranty Information
Booklet (US models)/Warranty and
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.<
