System limitations
The Flat Tire Monitor cannot pro-
vide you with advance warning of
sudden and severe tire damage caused
by external factors and does not detect
the balanced and very gradual pressure
loss that takes place in all four tires
over an extended period of time.<
On the other hand, the following situa-
tions can lead to a delayed detection of
pressure loss and even to the system
not functioning:
>Driving on snow-covered or slippery
roads
>Performance-oriented driving: slip at
the drive wheels, high levels of lateral
acceleration
>When driving with snow chains, false
warnings and undetected pressure
losses may occur
>When driving with a space-saver
spare tire, the Flat Tire Monitor can-
not function.
Initializing the system
Each time you correct the pres-
sure in a tire, or change a wheel or
tire, reinitialize the system immediately
afterwards. This requires a bit of driv-
ing.<
1. Before driving off, start the engine
but do not start driving
2. Press the button as long as you need
to, but no more than 10 seconds,
until the indicator lamp in the instru-
ment cluster lights up in yellow for a
few seconds
3. Drive off.
It takes a few minutes before the Flat
Tire Monitor can detect a flat tire and
issue a warning.
When driving with snow chains or
a space-saver spare tire, do not
initialize the system.<
Flat tire
The indicator lamp in the instru-
ment cluster lights up red. This
visual alert is accompanied by
an acoustic warning signal.
1. Carefully reduce speed and come to
a stop. Avoid sudden braking and
steering maneuvers
2. Determine which wheel is damaged
If this cannot be determined, con-
tact your BMW center.<
3. Replace the damaged wheel, refer to
Changing a wheel on page 157.
After replacing the damaged tire, initial-
ize the system.
Vehicles with Run Flat tires:
1. Carefully reduce your speed to under
50 mph / 80 km/h. Avoid sudden
braking and steering maneuvers. Do
not exceed a speed of 50 mph /
80 km/h

tire center, preferably your BMW cen-
ter. Observe any country-specific regu-
lations, e.g. on making a corresponding
entry in the vehicle documents.
The factory-approved radial belt tires
are matched to your vehicle and pro-
vide optimum safety and driving com-
fort when used properly.Run Flat tiresIf your vehicle is equipped with Run Flat
tires, refer to Run Flat tires, use only
these tires since no spare wheel is
available in the event of a flat.Special characteristics of winter
tiresBMW recommends the use of winter
tires for operation under winter road
conditions. While all-season tires with
M+S designation provide better winter
traction than summer tires, they gener-
ally do not achieve the full performance
of winter tires.
Run Flat tires:
If your vehicle is equipped with Run Flat
tires, refer to Run Flat tires, please note
the following: when mounting new tires
or replacing summer tires with winter tires, or vice versa, use only Run Flat
tires since no spare wheel is available
in the event of a flat. Your BMW center
wil be glad to advise you.
Observing speed ratings:
Never exceed the maximum
speed for which the winter tires
are rated. Unprofessional attempts by
laymen to service tires can lead to dam-
age and accidents. Have this work per-
formed by skilled professionals only.
The technicians at your BMW center
will be glad to assist you with the
required professional knowledge and
specialized equipment.<
StorageAlways 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. Do not
exceed the maximum tire inflation pres-
sures specified on the tire sidewall.
Snow chains*Only certain snow chains have been
tested by BMW and determined and
approved as roadworthy. Consult your
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.
Comply with all manufacturer's safety
precautions when mounting the chains.
Do not exceed a speed of 30 mph /
50 km/h when using snow chains.
You cannot mount snow chains with the
following tires:
>225/50 R 16
>225/45 R 17
>245/40 R 17
>225/40 R 18
>255/35 R 18.
Do not initialize the Flat Tire Moni-
tor after mounting snow chains to
the tires.
When driving with snow chains, it may
be useful to turn off the DSC for a short
time, refer to page 92.<

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.<
Your BMW is equipped with a space-
saver spare tire designed for temporary
use in maintaining the vehicle's mobility
in an emergency.
To remove the space-saver spare
tire, lift the floor panel in the lug-
gage 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 through
using them.
>Jack 1
Raise the floor panel in the luggage
compartment, refer to page 35, and
undo the jack.
When you have completed work, 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 wingnut to remove it
>Space-saver spare tire – next to jack
Loosen the wing nut by hand, remove
the storage shelf and take the wheel
out
>Lug wrench – in the onboard tool kit
on the underside of the luggage com-
partment lid, refer to page 152.Procedure1. Read and comply with the safety
precautions provided on the previ-
ous page
2. Secure the vehicle to prevent it
from rolling:
Place the chock 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 chock
securely 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
3. Wheels with full wheel covers*:
reach into the ventilation openings
and pull the cover off
4. If your vehicle is equipped with
Individual light-alloy wheels*: insert
the wheel puller supplied with the
vehicle into the designated recess
of the cover, and pull the cover off
5. Loosen the lug bolts by rotating
half a turn6. Position the jack at the jacking
point closest to the flat tire with the
jack base vertically below the jack-
ing point. The entire surface of the
head of the jack moves into the
square recess of the jacking point –
refer to the detail in the next illus-
tration – when the jack is cranked
7. Continue raising the vehicle up
until the wheel you are changing is
raised from the ground
8. Unscrew the lug bolts and remove
the wheel
9. Remove accumulations of mud and
dirt from the mounting surfaces of
the wheel and hub. Clean the lug
bolts
10. 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
11. Screw in the remaining lug bolts.
Screw in all the bolts in a diagonal
pattern
12. Lower the jack and remove it from
beneath the vehicle
13. Tighten the lug bolts securely in a
diagonal pattern

14. Wheels with full wheel covers*:
place the wheel cover with the
valve opening over the valve. Use
both hands to press the cover
securely onto the rim
15. Check and correct the tire inflation
pressure at the earliest opportunity.
Vehicles with Flat Tire Monitor:
After mounting the spare tire or
correcting the tire inflation pres-
sure, reinitialize the system, refer to
page 93.
Protect valve stems and valves from dirt
using screw-on valve stem caps. Dirty
valve stems frequently lead to slow
pressure loss.
Do not place 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 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.
Driving with the space-saver
spare tireDrive cautiously. Do not exceed a
speed of 45 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.<
