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.
Securing cargo
>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. Four lashing eyes
fitted in the luggage compartment are
used to secure these heavy-duty cargo
straps, refer to arrows
>Please observe the special instructions
supplied with the heavy-duty cargo
straps.
Always position and secure the load
as described above. 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 190, 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
maneuver.<
Pad on base of luggage
compartment
If required, you can use the pad e.g. to
transport dirty or soiled objects. The rub-
berized side is washable and has an anti-
slip effect.

Under the hood
170
Under the hood
Never attempt to perform any service
or repair operations on your vehicle
without the required, professional technical
training. If you are unfamiliar with the ser-
vice procedures and precautions, always
have any required work on your vehicle
carried out at your BMW center. If this work
is performed inexpertly, there is a danger of
damage and associated safety risks.<
Hood
Releasing
Pull the lever located under the left side of
the instrument panel.
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.
Make sure that the closing path of the
engine hood is clear, as otherwise
injuries may result.
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.<

>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.<

converter with the engine cold. It is better
to jump-start the engine, refer to page 184.
