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 – see arrow –
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 154.
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 sliding/tilt sunroof, and that
objects do not project into the opening
path of the tailgate.
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, please have the opera-
tions 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 determine while driving that the
hood is not completely closed, stop
immediately and close it securely.<

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 cargo area com-
pletely out, refer to page 109.<
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
Fold up the floor panel, lift away the
spare tire cover, and screw off the
red wingnut – see arrow.
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
Behind the vehicle jack. Loosen the
wingnut to remove it
>Lug wrench 3
>Spare tire or space-saver spare tire –
Located next to the jack.
Loosen the wingnut – see arrow – by
hand, remove the storage shelf and
take the wheel out.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. 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.<

BatteryMaintenanceThe battery is absolutely maintenance-
free, that is, the original electrolyte will
normally last for the service life of the
battery under moderate climatic condi-
tions.
Please consult your BMW center
whenever you have any questions
concerning the battery. Since the bat-
tery is absolutely maintenance-free, the
following is for your information only.<
Never disconnect the battery
when the engine is running; the
ensuing voltage surge would seriously
damage the vehicle's onboard elec-
tronic systems. 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.
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.<
