Tire Pressure Monitor (RDC)
*
In the event of a 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 is sounded.
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 case of a tire failure. It does not
have RDC electronics and is not moni-
tored. The spare tire
that has the same
dimensions as the tires already
mounted on the vehicle is equipped
with the necessary RDC electronics
and will be also 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 the information
needed for working with RDC and is
equipped with the necessary special
tools.<
System interferenceLocal 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.

Flat Tire Monitor
*
The conceptAs you drive, the Flat Tire Monitor
keeps track of pressure levels in all four
tires in order to detect and warn of any
substantial pressure loss.
The system actually detects pressure
loss by monitoring differences in the
relative speeds of the four wheels. It
interprets variations outside specified
limits as severe pressure loss, and then
responds by generating a warning.
Initializing the systemInitializing is necessary to familiarize the
system with the correct inflation pres-
sure.
Repeat this process after any changes
in tire inflation pressure, tire rotation or
replacement. Do not carry out further
system initialization after adjusting the
inflation pressure and letting the system
"learn" the correct pressures.
1. Check the tire inflation pressures in
all the tires, comparing them with the
inflation pressure chart on page 25
and adjusting their pressure if neces-
sary
2. Turn the ignition key to position 2
3. Press the button as long as you need
to until the indicator lamp on the
instrument cluster lights up. After a
little while, the indicator lamp will go
out by itself
4. After a few minutes driving time, the
Flat Tire Monitor adopts the current
pressure levels as the reference, and
from that point on, can detect and
report a flat tire.

Winter tiresChoosing the right tireBMW recommends winter tires (M+S
radial tires) for operation under
inclement winter driving conditions.
While all-season tires (M+S designa-
tion) provide better winter traction than
summer tires with the load ratings H, V,
W, Y and ZR, they generally do not
achieve the performance of 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.Never exceed the maximum
speed for which the winter tires
are rated.
Unprofessional attempts by laymen to
service tires can lead to damage and
accidents.
Have this work performed by trained
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
*
BMW narrow-link snow chains are
intended for mounting on summer or
winter tires in pairs at the rear wheels
only. Comply with all manufacturer's
safety precautions when mounting the
chains.
You cannot mount snow chains on the
following tires:
225/50 R 16 92
225/45 R 17 91
245/40 ZR 17

Changing a wheel
Safety precautions in the event of
a flat tire or wheel change:
Stop the vehicle as far as possible from
passing traffic. Park on a firm support
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 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 example).
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 local 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 either the vehicle or the
jack could slip sideways.
Position the jack on a firm support
surface.
Do not place wooden blocks or similar
objects under the jack. They could
prevent the jack from extending to its
full height and reduce its support
capacity.
Do not lie under the vehicle or start the
engine when the vehicle is supported
by the jack Ð risk of fatal injury.<
Your BMW is equipped with a spare tire
or a space-saver tire designed for
temporary use in maintaining the
vehicle's mobility in an emergency.
To remove the spare tire, lift the
floor panel in the luggage
compartment completely out, refer to
page 35.<
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 done
using them.
>Jack 1
Lift the floor panel within the luggage
compartment, refer to page 35 and
undo the red wingnut (arrow).
When you have completed work,
screw the jack all the way back
down. Fold the handle back and
insert it in its holder
>Chock 2
Located behind the jack on the wall
in the luggage compartment. Loosen
the wing nut to remove it

Changing a wheel>Spare tire
or space-saver spare tire
Located next to the jack.
Loosen the wing nut (arrow) by hand,
remove the storage shelf and take the
wheel out
>Lug wrench Ð in the onboard tool kit
on the underside of the luggage
compartment lid, refer to page 118.
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 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 from
rolling
3. Wheels with full wheel covers
*:
Reach into the ventilation openings
and pull the cover off4. Loosen the lug bolts by rotating half
a turn
5. Position the jack at the jacking point
closest to the flat tire (arrows) with
the jack base vertically below the
jacking point and the entire surface
of the head of the jack will move into
the square recess of the jacking
point (refer to the detail in the next
illustration) 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

Changing a wheelAlways use BMW-approved balance
weights on black-finished aluminum-
alloy wheels. Never allow anyone to
attempt to balance these wheels using
conventional rim-clip balance weights.Driving with the space-saver
spare tireDrive cautiously. Do not exceed a
speed of 50 mph (80 km/h).
You can anticipate changes in vehicle
handling such as delayed braking
response, longer braking distances and
sacrifices in roadholding.
The changes in handling characteristics
will be even more pronounced if winter
tires are mounted.
Only one space-saver spare tire
may be mounted at a time. Rein-
stall wheels and tires of the same size
and specification as soon as possible.
Maintain correct tire pressures. Refer to
page 25.<
Safety tires
*
Safety tires consists of self-contained
tires and special rims. The tire rein-
forcement ensures that the tire retains
some residual safety in the event of
pressure drop and driving remains
possible to a restricted degree. The
vehicle is equipped with Tire Pressure
Monitor (RDC) or Flat Tire Monitor,
which indicate a flat tire.Flat tireIf there is a tire failure, the red warning
lamp symbol lights up. A supplemen-
tary gong is also heard.
For additional information on Tire Pres-
sure Monitor (RDC) or Flat Tire Monitor
refer to pages 73 bzw. 75.
Reduce vehicle speed carefully to
under 50 mph (80 km/h), avoiding hard
brake applications and steering maneu-
vers.
With the safety tires, you can drive
another approx. 155 miles (250 km) to
reach a safe parking location, a service
station or the nearest BMW center.
With a low vehicle load, this can also be
considerably more than 155 miles
(250 km).Safety tires are only possible in
conjunction with Tire Pressure
Monitor (RDC) or Flat Tire Monitor.<
If the defective wheel can not be seen
as such immediately from the outside,
check the tire inflation pressure at all
four wheels.
Have the tires changed by your
BMW center. For safety reasons,
do not have a safety tire repaired. Your
BMW center has the information
needed for working with safety tires
and is equipped with the necessary
special tools.<
If appropriate, please consult your
BMW center to reequip your
vehicle from summer to winter tires Ð or
vice versa.<
