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 40, and
undo the red wing nut.
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
>Spare tire or space-saver spare tire –
located next to the 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 142.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 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 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 closest to the flat tire with the
jack base vertically below the jack-
ing point and 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
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 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 Flat Tire Monitor:
after mounting the spare tire or
correcting the tire inflation pres-
sure, reinitialize the system, refer to
page 92.
Protect valve stems and valves from dirt
using screw-on valve stem caps. Dirty
valve stems frequently lead to slow
pressure loss.

Driving with a damaged tireDepending on the cargo load, Run Flat
tires allow you to continue driving at a
maximum speed of 50 mph / 80 km/h. If
there is a total loss of tire inflation pres-
sure, 0 psi/0 kPa, or obvious tire dam-
age, you can determine the distance
you may continue driving based on the
following values:
>With a light load:
1 to 2 persons without luggage:
approx. 150 miles/250 km
>With a medium load:
2 persons, luggage compartment full;
or 5 persons without luggage:
approx. 100 miles/150 km
>With a full load:
5 persons, luggage compartment full:
approx. 30 miles/50 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.
For safety reasons, BMW recommends
not having damaged Run Flat tires
repaired. In this case, consult your
BMW center.<
BatteryMaintenanceThe battery is maintenance-free, that is,
the original electrolyte will normally last
for the service life of the battery under
moderate climatic conditions.
Please consult your BMW center
whenever you have any questions
concerning the battery. cle, leave the engine off at all times.
Connect the charge cables to the termi-
nals in the engine compartment. For
terminal locations, refer to Jump-start-
ing on page 153.Disposal
Return used batteries to a recy-
cling point or your BMW center.
Maintain the battery in an upright posi-
tion for transport and storage. Secure
the battery against tilting during trans-
port.<
FusesYou will find the fuses and information
on their respective allocation in the
glove compartment behind a panel with
two snap clips.
Do not attempt to repair a blown
fuse or replace it with a fuse
having a different color or amperage
rating. To do this could cause a fire in
the vehicle resulting from a circuit over-
load.<
