Alarm system
*
The conceptThe vehicle's alarm system responds:
>When a door, the hood or the lug-
gage compartment lid is opened
>To motion within the passenger com-
partment (interior motion sensor)
>To a change in the inclination of the
vehicle, e. g. during an attempted
wheel theft of unauthorized towing
>To interruption of battery voltage.
The alarm system signals unauthorized
access to the vehicle or an attempted
theft in different ways:
>Sounding an acoustical alarm for
30 seconds
>Activating the hazard warning flash-
ers for approx. five minutes
*.
To activate and deactivate the
alarm systemWhen the vehicle is locked or unlocked
by using a key or with the remote con-
trol, the alarm system is also simulta-
neously armed or disarmed.
The interior motion sensor is activated
approx. 30 seconds after you have fin-
ished locking the car.
If the alarm system has been armed
correctly, the hazard warning flashers
cycle once. An acoustic warning signal
sounds at the same time.
You can have various confirmation
messages set to inform you that
the alarm system has been armed or
disarmed.<
You can also open the luggage com-
partment lid when the system is armed
by pressing button 3 of the remote con-
trol (refer to page 37). When it is closed,
the lid is once again secured.
Indicator lamp displaysThe indicator lamp is located under the
inside rearview mirror.
>When the indicator lamp flashes
continuously: The system is armed
>The indicator lamp flashes when it is
armed: The door(s), the hood or lug-
gage compartment lid are not com-
pletely closed. Even if you do not
close the alerted area, the system be-
gins to monitor the remaining areas,
and the indicator lamp flashes contin-
uously after 10 seconds. However,
the interior motion sensor is not
activated
>If the indicator lamp goes out when
the system is disarmed: No manipula-
tion or attempted intrusions have
been detected in the period since the
system was armed460de105

Flat tireIf there is a tire failure with loss of pres-
sure, the indicator lamp comes on with
a red lamp. In addition, there is an
acoustical warning signal.
If this occurs, reduce vehicle speed im-
mediately and stop the vehicle in a save
location. Avoid hard brake applications.
Do not oversteer. Replace the wheel
and flat tire.
The space-saver spare tire
* is
provided for temporary use only in
the case 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 sys-
tem activated.<
The RDC cannot alert you to
severe and sudden tire damage
caused by external factors.<
Have the tires changed by your
authorized BMW center.
Your authorized BMW center has been
trained to work with the RDC system
and is equipped with the necessary
special tools.<
System interferenceThe RDC can be subjected to interfer-
ence locally by outside equipment or
devices which use the same radio fre-
quency.
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
appropriate electronics
>if, in addition to the spare tire
*, addi-
tional wheels with RDC electronics
are on board.
Please contact your authorized BMW
center for additional information.

Winter operationThe onset of winter is often accompa-
nied by rapid changes in weather. Adap-
tations in driving style should be accom-
panied by preparations on the vehicle
itself to ensure that your progress
through the winter remains safe and
trouble-free.CoolantBe sure that the coolant mixture is kept
at the year-round ratio of 50:50 of water
and antifreeze/corrosion protection.
This mixture provides protection against
freezing down to approx. – 347
(– 376). 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 deicer, 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 situation (snow chains mounted),
deactivate the DSC. Refer to page 81.
Starting offWe recommend that you use the man-
ual control switch to deactivate DSC
when starting off in deep snow or when
rocking the car to free it (refer to
page 81).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. Adapt
your speed and driving style when ap-
proaching grades or slopes. Maintain
an adequate distance between yourself
and the car ahead.
BrakesWinter road conditions substantially
reduce the traction available between
the tires and the road surface.
Remember that braking distances will
be significantly longer as a result.
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 in-
crease the pressure, reduce the pres-
sure 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.

Winter tiresChoosing the right tireBMW recommends winter tires (M+S
radial tires) for driving in adverse winter
road conditions. Although all-season
M+S tires provide better winter traction
than standard summer tires with H, V,
W, Y and ZR speed ratings, they gener-
ally fail to provide the same levels of
performance as standard snow tires in
winter driving.
For of safe tracking and steering re-
sponse, install winter tires made by the
same manufacturer having the same
tread configuration on all four wheels.
Mount only winter tires approved by
BMW. Any BMW center will be glad to
provide you with information on the
best winter tires for your particular driv-
ing conditions.Never exceed the maximum speed
for that 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. Your BMW center
will be glad to assist you with both their
expertise and the proper equipment for
your vehicle.<
Tire condition, tire pressureWinter tires display a perceptible loss in
their ability to cope with winter driving
conditions once the tread wears to be-
low 0.16 in (4 mm), and should thus be
replaced.
Comply with the specified tire inflation
pressures – and be sure to have the
wheel and tire assemblies balanced
every time you change the tires.
StorageStore tires in a cool, dry place, away
from light whenever possible. Protect
the tires against contact with oil, grease
and fuel.Snow chains
*
Use narrow-link BMW snow chains on
summer or winter tires only in pairs and
only on the rear wheels. Comply with all
manufacturer's safety precautions when
mounting the chains.

Changing tires
Take these precautionary mea-
sures if you have either a flat tire
or are changing the tire:
Park the vehicle as far from the flow of
traffic as possible and on firm ground.
Switch on the hazard flashers. Turn the
steering wheel to the straight-ahead
position, remove the key and engage
the steering lock. Shift into 1st or re-
verse (selector lever in "Park" with auto-
matic) and engage the parking brake.
All passengers should be outside the
car and well away from your immediate
working area (behind the 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 regula-
tions.
Change the wheel only on a level, firm
surface that is not slippery. Avoid jack-
ing the car on a soft or slippery support
surface (snow, ice, loose gravel, etc.),
as it could slide sideways.
Ensure that the jack is positioned on a
solid support surface.
Do not place wooden blocks or similar
objects under the jack. If this done, 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 – risk of fatal injury.<
Your BMW has either a spare
* or
space-saver tire
* for temporary use and
to ensure your mobility.

tions stated 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 down-
ward slope, place the wedge se-
curely in front of the tire. If the
wheel must be changed on a sur-
face with a more severe slope, take
additional precautions to secure the
vehicle from rolling

Reach into the ventilation openings
and pull the cover off462de251
4 Loosen the lug bolts 1/2 turn
5 Place the jack under the jacking
point nearest the wheel you are
changing (refer to the illustration at
the left) in such a way that the base
of the jack is positioned vertically
under the jacking point relative to
the entire surface, and that the jack
head fits securely into the square
recess of the jacking point (refer to
illustration detail) when the jack is
cranked

Changing tires Battery Driving with the space-saver
spare tire
*
Drive cautiously and do not exceed a
speed of 45 mph (80 km/h).
Be aware that vehicle handling will be
altered. Slower brake response time,
longer braking distances and changed
steering characteristics may be antici-
pated when approaching limit condi-
tions.
The changes in handling characteristics
will be even more pronounced in con-
junction with winter tires.
Only one space-saver spare tire
may be mounted. Mount a wheel
and tire with the same size and specifi-
cations as the others at the earliest
possible opportunity. Maintain correct
tire pressures. Refer to page 28.<
Battery location The battery is located at the right-rear
of the luggage compartment. Raise the
luggage compartment floor panel (refer
to page 41), and give a screwdriver or a
coin a 1/4-turn counterclockwise to
release the two fasteners plus an addi-
tional fastener in the upper-center side
trim panel. In order to remove the stor-
age tray, slide the side trim panel
slightly upward.460de176
SymbolsYou will find the following symbols on
your car battery. To avoid injury, please
comply with the corresponding precau-
tions whenever you work with or near
the battery.
Before handling the battery,
please read the following infor-
mation.
Wear eye protection. Do not al-
low particles containing battery
acid or lead to come into con-
tact with your eyes, your skin, or your
clothing.
Battery acid is extremely corro-
sive. Wear eye protection and
protective gloves. Do not tip the
battery. Battery acid can leak from the
ventilation openings.
Ensure that children keep well
away from batteries and battery
acid.
Fire, sparks, an open flame and/
or smoking are not allowed in
the vicinity of the battery. Avoid
sparks from electrical cables or electri-
cal equipment. Turn the key to position

Tire Pressure Control (RDC)
*
This system regularly checks tire pres-
sures and monitors all four tires even
while driving, so you don't have to.
Behind the valve stem in every wheel,
there is an extended-life electronic chip
that has a pressure sensor, a transmit-
ter and a battery. The pressure is mea-
sured in extremely short time intervals
and then transmitted by a radio signal.
If an irregularity is detected, the trans-
mission rate is increased. 462de257
Near every wheel there is an antenna in
the body that receives the signals from
all four wheels. A central electronics
system evaluates the quadruple signals
and forwards any changes. The RDC
plays an important part in driving safety.
