LoadThe permissible load is the sum of the
occupants' weights and the weight of
the cargo. The greater the weight of the
occupants, the less cargo can be trans-
ported.
Stowing cargo>Load heavy cargo as far forward as
possible – directly behind the back-
rests – and as low as possible
>Cover sharp edges and corners
>Do not pile objects higher than the
top edge of the backrest
>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 35
>For large, heavy pieces, see your
BMW center for load-securing
devices*. Four anchorages located in
the luggage compartment can be
used for fastening these load-secur-
ing devices.
Comply with the information enclosed
with the load-securing devices.
Always position and secure the
load correctly. If you do not, it can
endanger the passengers during brak-
ing or evasive maneuvers.
Do not exceed the approved gross
vehicle weight or the approved axle
loads, refer to page 156, 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 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
have 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 156.
Make sure that the load is not too bulky,
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 maintained for
raising the glass sunroof, and that
objects do not project into the opening
path of the luggage compartment lid.
Secure the roof-mounted luggage cor-
rectly and safely to prevent it from shift-
ing or being lost during driving.
Drive smoothly and avoid sudden
acceleration and braking. Do not corner
at high speeds.
The luggage rack and the roof load
increase aerodynamic resistance:
increased fuel consumption and addi-
tional 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. If you
are not familiar with the regulations to
be observed, have your vehicle ser-
viced only by a BMW center or a shop
that works according to BMW require-
ments with the appropriately trained
personnel. Work that is improperly car-
ried out could result in consequential
damage and pose safety hazards.<
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.<

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 spare tire
or a space-saver spare tire designed for
temporary use in maintaining the vehi-
cle's mobility in an emergency.
To remove the spare tire, lift the
floor panel in the luggage com-
partment 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.
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 136.Procedure1. Read and comply with the safety
precautions provided on the previ-
ous 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 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. 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 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
7. Jack 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 or
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 diagonal
pattern
12. Lower the jack and remove it from
beneath the vehicle

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 82.
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 load of any kind.
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.<

BatteryMaintenanceThe battery is completely maintenance-
free. This means that the original bat-
tery acid will normally last for the ser-
vice life of the battery under moderate
climate conditions. Your BMW center
will be glad to advise you if you have
any questions concerning the battery.Charging the batteryWhen charging the battery in the vehi-
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 147.Disposal
After changing the battery, have
the old battery disposed of by
your BMW center or bring it to a recy-
cling point. Maintain the battery in an
upright position for transport and stor-
age. Secure the battery against falling
over in transit.<
Power lossAfter a temporary power loss, e.g. due
to a discharged battery, some equip-
ment will be limited in its use and will
have to be reinitialized. Individual set-
tings are also lost and must be reset:
>Seat and mirror memory
The position settings must be stored
again, refer to page 47
>Clock
must be reset, refer to page 77
>Radio
Stations must be reset, refer to the
