LoadingVehicles with through-loading system:
1. Fold the center armrest outward.
Loosen the trim from the upper
Velcro® fastener and place it on the
armrest
2. Press the button downward – see
arrow 1 – and swing the cover for-
ward
3. Extend the ski bag between the front
seats. The zipper provides conve-
nient access to stored items. It may
be opened to allow the ski bag to dry
4. Press the button – see arrow 2: the
cover in the luggage compartment is
unlocked.
To store the ski bag, perform the above
steps in reverse sequence.
Securing cargo
Secure skis and any other objects
stored in the bag by tightening the
retaining strap at the buckle.<
Be sure that your skis are clean
before loading them into the bag.
Avoid damage from sharp edges during
loading.<
Cargo loading
Avoid overloading the vehicle so
that the permitted load on the tires
is not exceeded. Overloading can lead
to overheating and internal tire damage.
The ultimate result can assume the
form of a sudden air loss.<

>For transporting very heavy loads
when the rear seat is not occupied,
secure the outer safety belts in the
opposite buckles, refer to the illustra-
tion.
Securing cargo>For small, light items, use the rubber-
lined, non-skid side of the floor mat
or secure using a luggage compart-
ment net* or elastic straps, refer to
page 40
>For large, heavy pieces, see your
BMW center for load-securing
devices*. Anchorages located in the
luggage compartment can be used
for fastening the load-securing
devices.
Read and comply with the instructions
enclosed with the load-securing
devices.
Always position and secure loads
correctly. If you do not, the load
can endanger the passengers during
braking or evasive maneuvers.
Do not exceed the approved gross
vehicle weight or the approved axle
loads, refer to page 162. Otherwise the
vehicle's operating safety is no longer
assured and the vehicle will not be in
compliance with the certification regu-
lations.
Do not stow heavy or hard objects in
the passenger compartment without
securing them. Otherwise they would
be thrown around during braking and
evasive maneuvers and could endanger
the passengers.<

Roof-mounted luggage rack*A special roof-rack system is available
as an optional extra for your BMW.
Please observe the precautions
included with the installation instruc-
tions.AnchoragesAccess to the anchorages:
To fold up the covers, please use the
tool provided with the roof-rack system.Loading and driving notesRoof-mounted luggage racks raise the
center of gravity of the vehicle when
they are loaded. For this reason, they
exercise a major effect on the vehicle's
handling and steering response.
You should therefore always remember
not to exceed the approved roof load
capacity, the approved gross vehicle
weight or the axle loads when loading
the rack. These weights are listed under
Technical data on page 162.
Make sure that the load is not too
heavy, and attempt to distribute it
evenly. Always load the heaviest pieces
first so that they are at the bottom. Be
sure that adequate clearance is main-
tained for raising the glass sunroof, and
that objects do not project into the
opening path of the luggage compart-
ment lid.
Secure the roof-mounted luggage cor-
rectly and securely to prevent it from
shifting or being lost during driving.
Drive smoothly and avoid sudden
acceleration and braking. Do not corner
at high speeds.
The roof-mounted luggage rack and the
roof load increase the aerodynamic
resistance: increased fuel consumption
and additional stress on the vehicle's
body are the result.

HoodTo releasePull the lever located under the left-
hand side of the instrument panel.
Do not attempt to service your
vehicle if you do not have the
required technical background. Failure
to work in an informed, professional
manner when servicing components
and materials constitutes a safety haz-
ard for vehicle occupants and other
road users. If you are not familiar with
the guidelines, BMW recommends that
you have the operations performed by
your BMW center.<
To openPull the release handle and open the
hood.
To closeAllow the hood to fall from a height of
about 1 ft/30 cm so that it audibly
engages.
To avoid injuries, be sure that the
travel path of the hood is clear
when it is closed, following the same
safety precautions used in all closing
procedures.
If you notice while driving that the hood
is not completely closed, stop immedi-
ately and close it securely.<

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

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.<
