Alarm system
*
The conceptThe vehicle alarm system responds:
>When a door, the hood or the
luggage compartment lid 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
authorization, for example.
>If there is an interruption in battery
voltage.
The system responds to unauthorized
vehicle entry and attempted theft by
simultaneously activating the following:
>Sounding an alarm for 30 seconds.
>The hazard warning flashers are acti-
vated for approx. five minutes.
>The high beams flash on and off in
sync with the hazard warning flashers.
To activate and deactivate the
alarm systemWhen the vehicle is locked or unlocked
by using a key or with the remote
control, the alarm system is also simul-
taneously armed or disarmed.
The interior motion sensor and the tilt
alarm sensor are activated approx.
30 seconds after you have finished
locking the vehicle.
If the alarm system has been armed
correctly, the hazard warning flashers
flash once.
You can have a signal set as
acknowledgment for both arming
and disarming the alarm system.<
You can also open the luggage
compartment lid when the system is
armed by pressing button 3 of the
remote control (refer to page 37). When
it is closed, the lid is once again
secured.
Indicator lamp displaysThe indicator lamp is located under the
interior rearview mirror.
>When the indicator lamp flashes
continuously: the system is armed.
>If the indicator lamp flashes during
arming of the system: the door(s), the
hood or luggage compartment lid are
not properly closed. Even if you do
not close the indicated area, the
system begins to monitor the
remaining areas, and the indicator
lamp flashes continuously 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 armed.463us010

Tire Pressure Control (RDC)

*
In the event of a flat tire

If there is a tire failure with loss of pres-
sure, the indicator lamp comes on with
a red lamp. In addition, an acoustic
signal is sounded.
If this occurs, reduce vehicle speed
immediately to stop the vehicle in a safe
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 event of tire pressure loss. It does
not have RDC electronics and is not
monitored. A full-size spare tire that has
the same dimensions as the tires
already mounted on the vehicle is
equipped with the necessary RDC elec-
tronics, and will be also monitored once
the tires have been mounted and the
system activated.

<

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 interference

Local devices using the same radio
frequency can interfere with the RDC.
The yellow indicator lamp will come on
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 BMW center for
additional information.

Winter operationThe onset of winter is often accompa-
nied by rapid changes in weather.
Adaptations in driving style should be
accompanied 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
contains the year-round ratio of 50:50
water and extended-duty antifreeze/
corrosion protection. This mixture
provides protection against freezing
down 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, we recommend
you treat the door lock with BMW lock
cylinder lubricant.
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. *
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 rare situation, it may be effective
to deactivate the ASC+T/DSC system
for a brief period of time. Refer to
page 82.
Starting offWhen starting up 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 brief period of time. Refer to page 82.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. On down-
hill grades or slopes, shift down to the
next lower gear at an early point. Main-
tain an adequate distance between
yourself and the vehicle ahead.

Winter tires

Choosing the right tire

BMW 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 that have the H,
V, W, Y and ZR speed ratings, they
generally fail to provide the same levels
of performance as winter tires.
In the interest of safe tracking and
steering response, install winter tires
made by the same manufacturer having
the same tread configuration on all four
wheels.
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 pressure

Winter tires display a perceptible loss in
their ability to cope with winter driving
conditions once the tread wears to
below 0.16 in (4 mm), and therefore in
the interest of safety, should be
replaced.
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.

Storage

Always store tires in a cool, dry place.
Store them away from light whenever
possible. Protect the tires against con-
tact with oil, grease and fuel.

Snow chains

*
Use narrow-link BMW snow chains


on
winter tires only in pairs and only on the
rear wheels. Comply with all manufac-
turer's safety precautions when mount-
ing the chains.

Changing a wheel
Take these precautionary
measures if you have either a flat
tire or are changing the tire:
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 which is not slippery. Avoid
jacking 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. If this is
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. Failure to comply with this
creates a risk of fatal injury.< Your BMW has a spare tire
or a space-
saver spare tire for temporary use to
ensure your mobility.
To remove the spare tire, lift out
the floor panel in the luggage
compartment completely (refer to
page 41).<

Changing a wheelYou will need the followingIn 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 the floor panel in the luggage
compartment (refer to page 41) and
loosen the red wing nut (arrow).
When you have completed work,
screw the jack all the way back
down. Fold the handle back and
insert it in its holder.
>Wedge (2)
Located behind the jack on the wall
in the luggage compartment. Loosen
the wing nut to remove it.460de058
>Spare tire or space-saver spare tire
Next to the jack.
Loosen the wing nut (arrow) by hand,
remove the storage shelf and take the
wheel out.
>Lug wrench
In the onboard tool kit on the under-
side of the luggage compartment lid
(refer to page 152).460de059
Procedure1 Read and comply with the safety
precautions provided on the
previous page.
2 Secure the vehicle from 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
securely in front of the tire. If the
wheel must be changed on a
surface with a more severe slope,
take additional precautions to
secure the vehicle from rolling.
3 If your wheels are equipped with full
wheel covers
*: reach into the venti-
lation openings and pull off the
cover.

Changing a wheel
The vehicle jack is designed for
changing wheels only. Do not
attempt to raise another vehicle model
with it or to raise any load of any kind.
To do so could cause accidents and
personal injury.
To ensure continued safety, have the
tightness of the lug bolts checked with
a calibrated lug wrench [torque specifi-
cation: 72 lb.ft (100Nm)] at the earliest
opportunity.<
When storing the wheel, be sure that
you do not damage the retaining pin in
the spare tire recess.
If light-alloy wheels other than original
BMW light-alloy wheels have been
mounted, it may be necessary to use
different lug bolts for those wheels.
Replace the defective tire as soon as
possible and have the new wheel/tire
balanced.
For black-painted aluminum wheels
*,
use only those balancing weights
approved by BMW for use with light-
alloy wheels. Never attempt to balance
these wheels using standard balance
weights.
Driving with the space-saver
spare tireDrive cautiously and do not exceed a
speed of 50 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 anti-
cipated when approaching limit condi-
tions.
The changes in handling characteristics
will be even more pronounced in
conjunction with winter tires.
Only one space-saver spare tire

may be mounted at a time. Mount
a wheel and tire with the same size
and specifications as the others at the
earliest possible opportunity. Maintain
correct tire pressures. Refer to
page 28.<

Tire Pressure Control (RDC)*This system regularly checks tire pres-
sure and monitors all four tires even
while driving, so you do not have to.
Behind the valve stem in every wheel,
there is an extended-life electronic chip
that contains a pressure sensor, a
transmitter and a battery. The pressure
is measured in extremely short time
intervals and then transmitted by a
radio signal. If an irregularity is
detected, the transmission rate is
increased. 462de257
Located near each wheel and
embedded in the vehicle body is an
antenna that receives signals from the
wheel. A central electronics system
evaluates the quadruple signals and
forwards any changes.
The RDC provides an important contri-
bution to driving safety.
