Securing cargo
>Use the luggage net* or securing straps
to hold down small and lightweight lug-
gage and cargo, refer to page42
>Heavy-duty straps
* for securing larger
and heavier objects are available at
your BMW center. Anchorages for
attaching these heavy-duty straps have
been provided in your vehicle's luggage
compartment, refer to the illustration
>Please observe the special instructions
supplied with the anchorage fittings.
Always position and secure the load
beforehand as described above. If
you do not, it can even endanger the pas-
sengers during braking or evasive maneu-
vers.
Never exceed either the approved gross
vehicle weight or either of the approved
axle loads, refer to page216, as excessive
loads can pose a safety hazard, and may
also place you in violation of freeway safety
laws.
You should never transport heavy or hard
objects unsecured in the passenger com-
partment, as they could fly around and
pose a safety hazard to the vehicle's occu-
pants during abrupt braking or evasive
maneuvers .<
Roof-mounted luggage
rack*
Anchorage points
The anchorage points are located within
the door openings.
A special rack system is available as an
option for your BMW. Please comply with
the precautions included with the installa-
tion instructions.
Because roof racks raise the vehicle's cen-
ter of gravity when loaded, they have a
major effect on its handling and steering
response.
You should therefore always remember not
to exceed the approved roof weight, the
approved gross vehicle weight or the axle
loads when loading the rack.
You can find the specified weights in the
Technical data section on page216.
Make sure that the load is distributed
evenly, and that it does not extend outward
to beyond the limits of the loading surface.
Always load the heaviest pieces first – on
the bottom. Be sure that adequate clear-
ance is maintained for raising the glass
roof, and that objects do not project into
the opening path of the luggage compart-
ment lid.
Secure roof-mounted cargo correctly and
securely to prevent it from shifting or being
lost during the trip.
Drive smoothly. Avoid sudden acceleration
and braking maneuvers. Take corners gen-
tly.

Under the hood

Under the hood
Never attempt to perform any service
or repair operations on your vehicle
without the required, professional technical
training. If you are not familiar with the reg-
u l a t i o n s t o b e o b s e r v e d , o n l y h a v e w o r k o n
your vehicle carried out by a BMW center
or a workshop that uses personnel trained
in accordance with BMW requirements. If
this work is not carried out properly, there
is a danger of subsequent damage and
related safety hazards.<
Hood
Unlocking
Pull the lever located under the left side of
the instrument panel.
Opening
Pull the release handle and open the hood.
Closing
Close the hood from a height of approx.
16 in/40 cm with momentum. It must be
clearly heard to engage.
Observe the same precautions that
apply to all closing operations by
ensuring that the hood's travel range is
clear and unobstructed before allowing the
hood to fall into position.
If you see any signs that the hood is not
completely closed while you are driving
your vehicle, you should stop at once and
close it securely.<

of the tire. On a steep grade, also
secure the vehicle against rolling
3.Loosen the lug bolts 1/2 a turn.
Lifting vehicle
1.Position the jack at the jacking point
closes to the wheel so that the entire
jack base makes contact vertically
under the jacking point
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.<2.Guide the jack head into the rectangular

ent lug bolts may also be required
4.Screw in the remaining lug bolts.
Tighten all the bolts securely in a diag-
onal pattern
5.Lower the vehicle and remove the jack
from beneath the vehicle.
Following installation
1.Tighten the lug bolts in a diagonal pat-
tern
To ensure safety, always have the
lug bolts checked with a cali-
brated torque wrench as soon as possi-
ble to ensure that they are tightened to
the specified torque. The tightening
torque is 140 Nm.<

Battery
Battery care
The battery is 100 % maintenance-free, i.e.,
the electrolyte will last for the life of the bat-
tery when the vehicle is operated in a tem-
perate climate. Your BMW center will be
happy to advise you on all questions con-
cerning the battery.
Charging battery
Only charge the battery in the vehicle via
the terminals in the engine compartment
with the engine off. Connections, refer to
Jump-starting on page210.
Battery switch
Before storing the vehicle for an extended
period of several weeks or more, slide the
battery switch located behind the trim
panel on the right side of the luggage com-
partment to OFF. This reduces the current
flow from the battery for the period during
which the vehicle remains parked. A mes-
sage appears in the Check Control. Please
take note of the supplementary information
provided on the Control Display.
Disposal
Have old batteries disposed of follow-
ing replacement at your BMW center
or bring them to a collection point. Maintain
the battery in an upright position for trans-
port and storage. Always secure the battery
to prevent it from tipping over during trans-
port.<
Power failure
Following a temporary power failure, e.g. in
the case of a flat battery, some equipment
is subject to restricted use and must be
reinitialized. Individual settings are also lost
and must be updated again:
>Seat, mirror and steering wheel memory
The positions must be stored again,
refer to page55
>Time and date
Must be updated again, refer to
page90
>Radio
Stations must be stored again, refer to
page 154
>Navigation system
The operability must be waited for, refer
to page130.
Fuses
Never attempt to repair a blown fuse,
and do not replace a defective fuse
with a substitute of another color or amper-
age rating, as this could lead to a circuit
overload, ultimately resulting in a fire in the
vehicle.<
Spare fuses are located on the fuse strip in
the glove compartment; plastic tweezers
can be found at the fuse holder in the lug-
gage compartment.
In glove compartment
Press the tab on the cover to the front, then
fold up the cover.

release of the transmission lockout,
refer to page70. Do not exceed a towing
speed of 45 mph/70 km/h and a towing dis-
tance of 90 miles/150 km, as otherwise the
automatic transmission may be dam-
aged.<
Towing methods
In some countries, towing with tow bars or
ropes in public traffic is not permitted.
Familiarize yourself with the regulations on
towing in the respective country.
With tow bar
The towing vehicle may not be lighter
than the vehicle to be towed, other-
wise it mill not be possible to control vehi-
cle response.<
The tow fittings used should be on the
same side on both vehicles. Should it prove
impossible to avoid mounting the tow bar
at an offset angle, please observe the fol-
lowing:
>Clearance and maneuvering capability
will be strictly limited in corners
>When mounted at an angle, the tow bar
will exert lateral forces, tending to push
the vehicle sideways.
Secure the tow bar on the tow fitting
only. Otherwise damage could result
on other vehicle parts.<
With tow-rope
When starting off in the towing vehicle,
make sure that the tow-rope is taut.
To avoid jerking and the associated
stresses on vehicle components
when towing, always use nylon ropes or
nylon straps. Secure the tow rope on the
tow fitting only. Otherwise damage could
result on other vehicle parts.<
With tow truck
Have the BMW transported with a tow truck
with a so-called lift bar or on a load bed.
Do not lift vehicle by tow fitting or
body and chassis parts, as otherwise
damage may result.<
