2015 BMW 3 SERIES ACTIVE HYBRID ECU

LoadingVehicle features and options
This chapter describes all standard, country-
specific and optional features offered with the
series. It also describes features that are not
necessarily available in your car, e. g., due to
the selected options or country versions. This
also applies to safety-related functions and
systems. The respectively applicable country
provisions must be observed when using the
respective features and systems.
Hints Overloading the vehicle
To avoid exceeding the approved ca‐
pacity of the tires, never overload the vehicle.
Overloading can lead to overheating and in‐
creases the rate at which damage develops in‐
side the tires. This could result in a sudden
loss of tire inflation pressure.◀
No fluids in the cargo area
Make sure that fluids do not leak into the
cargo area; otherwise, the vehicle may be dam‐
aged.◀
Heavy and hard objects
Do not stow any heavy and hard objects
in the car's interior without securing them; oth‐
erwise, they may present a danger to occu‐
pants, e.g., during braking and evasive maneu‐
vers.◀
Determining the load limit1.Locate the following statement on your ve‐
hicle’s placard:▷The combined weight of occupants
and cargo should never exceed XXX kg
or YYY lbs. Otherwise, damage to thevehicle and unstable driving situations
may result.2.Determine the combined weight of the
driver and passengers that will be riding in
your vehicle.3.Subtract the combined weight of the driver
and passengers from XXX kilograms or
YYY pounds.4.The resulting figure equals the available
amount of cargo and luggage load ca‐
pacity.
For example, if the YYY amount equals
1,000 lbs and there will be four 150 lbs
passengers in your vehicle, the amount of
available cargo and luggage load capacity
is 400 lbs: 1,000 lbs minus 600 lbs =
400 lbs.5.Determine the combined weight of lug‐
gage and cargo being loaded on the vehi‐
cle. That weight may not safely exceed the
available cargo and luggage load capacity
calculated in Step 4.Seite 177LoadingDriving tips177

Load
The maximum load is the sum of the weight of
the occupants and the cargo.
The greater the weight of the occupants, the
less cargo that can be transported.
Stowing cargo
▷The cover of the high-voltage battery is lo‐
cated in the trunk. Do not remove the cover
to stow luggage.▷Cover sharp edges and corners on the
cargo.▷Heavy cargo: stow as far forward as possi‐
ble, directly behind and at the bottom of
the rear passenger seat backrests.▷Very heavy cargo: when the rear seat is not
occupied, secure each of the outer safety
belts in the opposite buckle.▷If necessary, fold down the rear backrests
to stow cargo.▷Do not stack cargo above the top edge of
the backrests.Securing cargo
Lashing eyes in the trunk
To secure the cargo there are four lashing
eyes in the cargo area.
Floor net
The floor net can also be used to secure cargo
and store small parts.
Hook the floor net into the fittings in the trunk
floor.
Securing cargo Securing cargo
Stow and secure the cargo as described;
otherwise it may present a danger to the occu‐
pants, e.g., during braking and evasive maneu‐
vers.◀
▷Smaller and lighter items: secure with re‐
taining straps or draw straps.▷Larger and heavy objects: secure with
cargo straps.
Attach the cargo straps, retaining straps or
draw straps to the lashing eyes in the trunk.

Roof-mounted luggage rackNoteRoof racks are available as special accessories.
Securing Follow the installation instructions of the roof
rack.
Roof drip rail with flaps
The anchorage points are located in the roof
drip rail above the doors.
Fold the cover outward.
Loading Be sure that adequate clearance is maintained
for tilting and opening the glass sunroof.
Because roof racks raise the vehicle's center
of gravity when loaded, they have a major ef‐
fect on vehicle handling and steering re‐
sponse.
Therefore, note the following when loading
and driving:
▷Do not exceed the approved roof/axle
loads and the approved gross vehicle
weight.▷Distribute the roof load uniformly.▷The roof load should not extend past the
loading area.▷Always place the heaviest pieces on the
bottom.▷Secure the roof luggage firmly, e.g., tie
with ratchet straps.▷Do not let objects project into the opening
path of the trunk lid.▷Drive cautiously and avoid sudden acceler‐
ation and braking maneuvers. Take corners
gently.Seite 179LoadingDriving tips179
