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

Automatic transmission with Steptronic
*
You have the option of driving with a
normal automatic transmission or
switching to manual.
When you move the selector lever from
the "D" position to the left into the M/S
range, the performance-oriented shift
programs of the automatic transmission
are engaged. As soon as you tap the
selector lever in the "+" or "Ð" direction,
Steptronic changes the gear. The
manual mode is engaged. Whenever
you want to use the automatic mode
again, move the selector lever to the
right into position "D."
The automatic transmission with Step-
tronic is equipped with Adaptive Trans-
mission Control (ATC). ATC reacts with
precision to your individual driving style
and the current driving conditions. It is
for this reason that various shift
programs are used.
For additional information concerning
the ATC, please refer to the chapter
describing "Advanced technology" on
page 173.
Selector lever positions
P R N D M/S + Ð
Starting the engineThe engine can only be started in
selector lever positions P ("Park") or N
("Neutral").Range selectionA detent prevents inadvertent shifts into
some selector lever positions. To
release the shift-lock mechanism, press
the button on the front side of the
selector handle (arrow).463de061
While the vehicle is stationary
and before shifting out of "Park" or
"Neutral," depress the footbrake, other-
wise the selector lever will be blocked
(shiftlock).
Hold the footbrake down until starting
off. Otherwise the vehicle will "creep"
when a drive position is engaged.<
Before leaving the vehicle with the
engine running, move the selector
lever to the "Park" or "Neutral" position
and apply the parking brake. The
vehicle will move if this is not done. Do
not leave the vehicle unattended with
the engine running. An unattended
vehicle with a running engine repre-
sents a potential safety hazard.<
P ParkSelect "Park" only when the vehicle is
stationary. The transmission locks to
prevent the rear wheels from turning.R ReverseSelect "Reverse" only when the vehicle
is stationary.N Neutral Select "Neutral" only if your journey is
interrupted for a longer period.

Tire Pressure Control (RDC)
*
Flat tireIf there is a tire failure with loss of pres-
sure, the indicator lamp comes on with
a red lamp. In addition, an acoustic
signal goes off.
If this occurs, reduce vehicle speed
immediately and stop the vehicle in a
safe location. Avoid hard brake applica-
tions. Do not oversteer. Replace the
wheel and flat tire.
The space-saver spare tire is
provided for temporary use only
in the event of a tire failure. It does not
have RDC electronics and is not moni-
tored. A full-size spare tire
that has the
same dimensions as the tires already
mounted on the vehicle is equipped
with the necessary RDC electronics,
and will also be monitored once the
tires have been mounted and the
system activated.<
The RDC cannot alert you to
severe and sudden tire damage
caused by external factors.<
Have the tires changed by your
BMW center.
Your BMW center has been trained to
work with the RDC system and is
equipped with the necessary special
tools.<
System interferenceThe RDC may encounter interference
from outside equipment or devices
which use the same radio frequency.
The indicator lamp will come on with
a yellow lamp during the malfunction.
The indicator lamp also comes on
>in the event of a system fault
>if a wheel is mounted without the
RDC electronics
>if, in addition to the spare tire, addi-
tional wheels with RDC electronics
are on board.
Please contact your BMW center for
additional information.

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.

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

Procedure1 Read and comply with the safety
precautions provided on the
previous page.
2 Secure the vehicle against rolling:
Place the wedge against the rear
surface of the front tire on the side
opposite the side being raised. If the
vehicle is parked on a downward
slope, place the wedge securely in
front of the tire. If the wheel must
be changed on a surface with a more
severe slope, take additional precau-
tions to secure the vehicle against
rolling.
3 If your wheels are equipped with full
wheel covers
*: reach into the ventila-
tion openings and pull the cover off.
460de124
4 Loosen the lug bolts g turn.
5 Position the jack under the jacking
point nearest the wheel you are
changing (refer to the illustration at
the left) so that the base of the jack is
positioned vertically under the jack-
ing point relative to the entire surface,
and that the jack head fits securely
into the square recess for the jacking
point (refer to illustration detail) when
the jack is cranked.
6 Jack the vehicle up until the wheel
you are changing is raised from the
ground.
7 Unscrew the lug bolts and remove
the wheel. 460de190

Changing a wheel Battery Driving with the space-saver tireDrive cautiously. Do not exceed a speed
of 50 mph (80 km/h).
You can anticipate changes in vehicle
handling such as delayed braking re-
sponse, longer braking distances and
changes in self-steering properties in
marginal stability limits.
The changes in handling characteristics
will be even more pronounced in
conjunction with winter tires.
Only one space-saver tire may be
mounted at one time. Reinstall
wheels and tires of the same size and
specification as soon as possible.
Maintain correct tire pressures. Refer to
page 29.<
Installation locationThe battery is in the right rear of the
luggage compartment. Release side
trim panel and remove. Fold back the
cover panel.
Battery posts, terminals, and
related accessories contain lead
and lead compounds. Wash hands after
handling.<
Charge conditionYou can read the charge condition
of the battery with the "Magic Eye
*"
(= a hydrometer):
>Green: adequate charge.
>Black: not charged adequately.
The battery must be recharged.
Please contact your BMW center
for additional information.
>Yellow: replace the battery.
The service life specified for the
battery can be achieved only if it is
always kept adequately charged. If the
vehicle is primarily used for stop-and-
go traffic, be sure to check the charge
status often.<
