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
defective tire, refer to page 141.
The space-saver spare tire is pro-
vided for temporary use only in the
case of a tire failure. It does not have
TPM electronics and is not monitored.
The spare tire that has the same dimen-
sions as the tires already mounted on
the vehicle is equipped with the neces-
sary TPM electronics and will be also
monitored once the tires have been
mounted and the system initialized.<
The TPM 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 TPM and is
equipped with the necessary special
tools. quency can interfere with TPM.
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 TPM electronics
are on board.
Please refer the problem to your BMW
center.
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.

Driving notes
Brakes: do not drive with your foot
resting on the brake pedal. Even
light but consistent pressure on the
brake pedal can lead to high tempera-
tures, accelerated brake wear and pos-
sibly even brake failure.
Hydroplaning: when driving on wet or
slushy roads, reduce your speed. If you
do not, a wedge of water may form
between tires and road surface. This
phenomenon can lead to partial or
complete loss of contact between the
tires and road surface, as well as loss of
vehicle control and braking ability.
Driving through water: do not drive
through water on the road if it is deeper
than 1 ft/30 cm, and then only at walk-
ing speed. Otherwise, the vehicle's
engine, the electrical systems and the
transmission may be damaged.
Cargo area cover: never use it to store
heavy or hard objects, as otherwise
occupants could be injured during
braking maneuvers.
Clothes hooks: when hanging clothing
from the hooks, be sure that they will
not obstruct the driver's vision. Do not
hang heavy objects on the hooks. If you
do so, they could cause personal injury
during braking or evasive maneuvers.<
Antilock Brake System (ABS)The conceptABS keeps the wheels from locking
during braking, thereby enhancing
active driving safety.Braking with ABSIf you are in a situation that requires full
braking, you will exploit the full benefits
of ABS system if you apply maximum
pedal pressure – panic stop. Since the
vehicle maintains steering responsive-
ness, you can avoid possible obstacles
with a minimum of steering effort,
despite the full brake application.
Pulsation at the brake pedal combined
with sounds from the hydraulic circuits
indicates to the driver that ABS is in its
active mode.Dynamic Brake Control (DBC)DBC is included in the DSC, refer to
page 80.
The system responds to sudden, high-
intensity applications of force to the
brake pedal by automatically braking
the vehicle with maximum boost to
achieve the shortest-possible braking
distances during "panic stops". This
system exploits all the benefits of ABS.Do not reduce the pressure exerted
against the brake pedal until the brak-
ing maneuver has been completed.
DBC is deactivated when you release
the brake pedal.
Cornering Brake Control (CBC)CBC is an advanced engineering devel-
opment of ABS. When braking during
cornering with high lateral accelera-
tion, or when braking during a lane
change, vehicle stability is improved
and the steering response is enhanced.

Tire condition, tire pressureAt tread depths below approx. 3/16 in /
4 mm, winter tires display a perceptible
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 — and be sure to have the
wheel and tire assembly balanced
every time you change a tire or wheel.Snow chains*Only certain snow chains have been
tested by BMW and determined and
approved as roadworthy. Consult any
BMW center for details. BMW recom-
mends using only these approved fine-
link snow chains. Use them in pairs on
either summer or winter tires, but only
on both rear wheels.
BMW 325xi: in an extreme emergency –
for instance, with the vehicle stuck on
one side, or when obstructions make it
impossible to reach one tire – a chain
may also be mounted on just one tire
for the limited period needed to resolve
the problem.
Comply with all manufacturer's safety
precautions when mounting the chains.
Do not exceed a speed of 30 mph /
50 km/h when unsing snow chains.You cannot mount snow chains on the
following tires:
225/50 R 16
225/45 R 17
245/40 R 17
225/40 R 18
255/35 R 18Winter tires

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, flat, sur-
face. Switch on the hazard warning
flashers. Turn the steering wheel to the
straight-ahead position and engage the
steering lock. Shift into 1st or Reverse,
or if you have an automatic transmis-
sion, position the selector lever in Park,
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 local safety guidelines and reg-
ulations.
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 sur-
face.
Do not place wooden blocks or similar
objects under the jack. They could pre-
vent 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. There is otherwise a risk of
fatal injury.<

wheel must be changed on a sur-
face with a more severe slope, take
additional precautions to secure
the vehicle from rolling
3. Wheels with full wheel covers*:
reach into the ventilation openings
and pull the cover off
4. Loosen the lug bolts by rotating
half a turn
5. Position the jack at the jacking
point – see arrows – closest to the
flat tire so that the jack base is ver-
tically below the jacking point and
the entire surface of the head of the
jack moves into the square recess
of the jacking point when the jack
is cranked – refer to the detail in the
next illustration
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
8. Remove accumulations of mud or
dirt from the mounting surfaces of
the wheel and hub. Clean the lug
bolts
9. Position the new wheel or the
space-saver spare tire on the hub
and screw at least two lug bolts fin-
ger-tight into opposite bolt holes
10. Screw in the remaining lug bolts.
Screw in all the bolts in a diagonal
pattern
11. Lower the jack and remove it from
beneath the vehicle
12. Tighten the lug bolts securely in a
diagonal pattern

13. Wheels with full wheel covers*:
place the wheel cover with the
valve opening – see arrow – over
the valve. Use both hands to press
the cover securely onto the rim
14. Check and correct the tire inflation
pressure at the earliest opportunity.
Vehicles with Tire Pressure Monitor
(TPM)/Flat Tire Monitor: after
mounting the spare tire or correct-
ing the inflation pressure, reinitial-
ize the system, refer to page 85
or 86.
Protect valve stems and valves from dirt
using screw-on valve stem caps. Dirty
valve stems frequently lead to slow
pressure loss.
Do not attempt to install the full
wheel cover on the space-saver
spare tire, since this could damage the
cover.<
The vehicle jack is designed for
changing wheels only. Do not
attempt to raise another vehicle model
with it or to raise any other type of load.
To do so could cause accidents and
personal injury.
To ensure continued safety, have the
tightness of the torque bolts checked
with a calibrated lug wrench – torque
specification: 88.5 lb ft/120 Nm – at the
earliest opportunity.<
When storing a wheel in the spare tire
recess, take care to avoid bending the
threaded rod.
If the original BMW light-alloy wheels
have been replaced with other light-
alloy wheels, different lug bolts may be
required.
Replace the defective tire as soon as
possible and have the new wheel/tire
balanced.
Driving with the space-saver
spare tireDrive cautiously. Do not exceed a
speed of 50 mph / 80 km/h.
Be aware that vehicle handling may be
altered. Anticipate, e.g., reduced track-
ing during braking, longer braking dis-
tances, and changed steering charac-
teristics when approaching limit
conditions. These handling characteris-
tics will be even more pronounced if
winter tires are mounted.
Only one space-saver spare tire
may be mounted at one time.
Mount a wheel and tire of the original
size at the earliest possible opportu-
nity. For certain wheel/tire combina-
tions, the size of the spare tire will
differ from that of the remaining tires.
The spare tire is fully functional at all
loads and speeds. However, the spare
tire should be replaced at the earliest
possible opportunity in order to achieve
the original operating conditions.<

Run Flat tires*Run Flat tires are labeled on the side-
wall with a circular symbol containing
the letters RSC. Run Flat tires consist of
self-supporting tires and special rims.
The tire reinforcement 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 a Tire
Pressure Monitor (TPM) or Flat Tire
Monitor, which indicate a flat tire.
Because the sides of Run Flat
tires are reinforced, a drop in infla-
tion pressure usually cannot be
detected from the outside.<
Flat tireIf there is a tire failure, the red warning
lamp symbol lights up. This visual alert
is accompanied by an acoustic warning
signal.
Additional information on the Tire Pres-
sure Monitor (TPM) or Flat Tire Monitor
is found beginning on page 85.
Reduce vehicle speed carefully to
under 50 mph / 80 km/h, avoiding hard
brake applications and steering maneu-
vers.
If the defective wheel is not immedi-
ately recognizable on the outside,
check the tire pressure at all four
wheels.
Have Run Flat tires replaced by
your BMW center. In the interest
of safety, Run Flat tires should not be
repaired. Your BMW center has the
information needed for working with
Run Flat tires and is equipped with the
necessary special tools.<
If appropriate, please consult your
BMW center to reequip your vehi-
cle from summer to winter tires – or vice
versa.<
Driving with a damaged tireRun Flat tires allow you to continue
driving to a restricted degree at a maxi-
mum speed of 50 mph / 80 km/h
depending on the cargo load and the
extent of tire damage. You can deter-
mine the distance you may continue
driving on the basis of the following val-
ues:
>Tire inflation pressure of
0 psi/0 kilopascal (kPa):
approx. 100 miles/150 km
>Tire inflation pressure of approx.
7-15 psi/50-100 kPa:
approx. 300 miles/500 km
>Tire inflation pressure greater than
15 psi/100 kPa:
approx. 600 miles/1,000 km.
Drive cautiously. Do not exceed a
speed of 50 mph / 80 km/h. Be
aware that vehicle handling will be
altered when there is a loss in inflation
pressure. Anticipate, e.g., reduced
tracking during braking, longer braking
distances and changed steering char-
acteristics.<
