Stowing cargo
>Load heavy cargo as far forward and as
low as possible, placing it directly
behind the bulkhead behind the rear
seats
>Cover sharp edges and corners
>For very heavy cargo when the rear seat
is not occupied, secure each safety belt
in the opposite buckle.
Securing the load
>Use the luggage net* or securing straps
to hold down small and lightweight lug-
gage and cargo
>Heavy-duty cargo straps
* for securing
larger and heavier objects are available
at your BMW center. Lashing eyes
mounted in the corners of the luggage
compartment are used to secure this
load securing equipment, refer to illus-
tration
>Please observe the special instructions
supplied with the heavy-duty cargo
straps.
Always position and secure the load
correctly. If you do not, it can even
endanger the passengers during braking or
evasive maneuvers.
Never exceed either the approved gross vehicle weight or either of the approved
axle loads, refer to page 200, 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
even pose a safety hazard to the vehicle's
occupants 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 page 200.
Make sure that the load is not too heavy,
and that it does not extend outward to
beyond the limits of the loading surface.
Always load the heaviest pieces first Ð at
the bottom. Be sure that adequate clear-
ance is maintained for raising the glass

Things to remember when driving
110 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
Hood
Unlocking
Pull the lever located under the left side of
the instrument panel.
Never attempt to perform any service
or repair operations on your vehicle
without the required, professional technical
training. When you are unfamiliar with the
service procedures and precautions,
always have any required work carried out
at your BMW center. Unprofessional
attempts at service and repair, and the
incorrect handling of parts and materials
that can occur during such attempts, con-
stitute a potential safety hazard, both for
the vehicle's occupants and for other road
users.<
Opening
Press the release handle and open the
engine 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 driving your vehi-
cle, you should stop at once and close it
securely.<

Changing a wheel
Safety measures in the event of a
breakdown or wheel change:
Park the vehicle as far away as possible
from moving traffic and on firm ground.
Switch on the hazard warning flashers.
Lock the steering wheel in straight-ahead
setting of the wheels. Apply the handbrake
and engage first gear, reverse gear or
selector lever to position P.
Have all vehicle occupants get out of the
vehicle and ensure that they remain outside
the immediate area in a safe place, such as
behind a guardrail.
If a warning triangle or portable hazard
warning lamp is required, set it up on the
roadside at an appropriate distance from
the rear of the vehicle.
Comply with all safety guidelines and regu-
lations.
Change the wheel only on a level, firm sur-
face which is not slippery.
The vehicle or the jack could slip to the side
if you attempt to raise the vehicle on a soft
or slippery surface such as snow, ice, tiles,
etc.
Position the jack on a firm support surface.
Do not use a wooden block or similar
object as a support base for the jack, as
this would prevent it from extending to its
full support height and reduce its load-car-
rying capacity.
To avoid serious or fatal injury: never lie
under the vehicle, and never start the
engine while it is supported by the jack.<
What you will need
To avoid rattling noises later on, note the
positions of the tools before removing
them, then return them to their initial posi-
tions after completing work.1Chock
2Vehicle jack
3Lug wrench
are located in the tool space in the rim of
the compact wheel. Raise the floor mat and
the cover beneath it. Take out the required
tool(s). After using the tools, return them to
the storage space.
Compact wheel*
1.Unscrew the wing nut 1
2.Remove the disk 2 to the side
3.Take out the tool brackets 3
4.Remove the compact wheel.
Procedure
1.Read carefully and comply with the
safety precautions on left-hand column
2.To secure the vehicle against move-
ment:
Place the wheel chock behind the front
wheel on the side opposite the side
being raised. If the vehicle is parked on
a downward slope, place the chock in
front of the wheel. If the wheel must be
changed on a surface with a more
severe slope, take additional precau-
tions to secure the vehicle from rolling

Replacing components
188 3.Loosen the lug bolts 1/2 a turn
4.Set up the jack beneath the jacking
point closest to the flat tire. Ensure that
the entire surface of the jack's base is in
firm contact with the ground and that
the jack itself is standing completely
vertical, not tilted, and that the fitting on
the top of the jack will align with the
rectangular recess on the vehicle when
you raise it, refer to illustration
5.Jack the vehicle up until the wheel you
are changing is raised from the ground
6.Unscrew the lug bolts and remove the
wheel
7.Remove accumulations of mud or dirt
from the mounting surfaces of the
wheel and hub. Clean the lug bolts
8.Position the new wheel or compact
wheel. Secure the wheel by turning at
least two lug bolts into opposite bolt
holes
9.Screw in the remaining lug bolts.
Tighten all the bolts securely in a diag-
onal pattern
10.Lower the jack and remove it from
beneath the vehicle
11.Tighten the lug bolts in a diagonal pat-
tern
12.Check and correct the tire inflation
pressure at the earliest opportunity.
Protect valve stems and valve stem
seal caps against dirt and contamina-
tion. Dirt in valve stems is a frequent source
of gradual air loss.<
After mounting the wheel or correcting the
inflation pressure, reinitialize the Flat Tire
Monitor, refer to page 81.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 safety, always have the lug bolts
checked with a calibrated torque wrench
as soon as possible to ensure that they are
tightened to the specified torque.
The tightening torque is 120 Nm.<
Reverse the removal sequence to store the
wheel and tools in the vehicle.
When you mount wheels other than Genu-
ine BMW light-alloy wheels, different lug
bolts may also be required.
Always have damaged tires replaced and
the wheel and tire assembly rebalanced at
the earliest possible opportunity.
Driving with the compact wheel
Drive reservedly and do not exceed a
speed of 50 mph/80 km/h.
The driving characteristics change, for
example reduced track stability on braking,
extended braking distance, and altered
self-steering characteristics in the limit
range. In conjunction with winter tires,
these characteristics are more pro-
nounced.
Only one compact wheel may be
mounted. You should fit wheels and
tires of the original size as quickly as possi-
ble.<
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.
For all questions that regard the bat-
tery, please consult your BMW cen-
ter.<
