Removing the storage compartment
The storage compartment can be removed
completely to be able to use other inserts, for
example.
In the cargo area: Press the handle up and fold
the storage compartment completely down.
For more information on the various
inserts available, contact your BMW
center.<
Lateral storage shelf behind the seats
This space can be used to store briefcases, for
example.
When loading the lateral storage shelf, do
not move both seats all the way forward
while moving them to their uppermost position
and leaning the backrests forward. Otherwise,
the seats could hit and damage the seal on the
windshield and the sun visor.
Only transport light and small objects on the lat-
eral storage shelf; otherwise, braking maneu-
vers and swerving may lead to a safety hazard
due to objects flying about the passenger com-
partment. Only transport heavy luggage in the
cargo area if it has been appropriately
secured.<
Cupholders*
Use lightweight and shatterproof contain-
ers and do not transport hot beverages;
otherwise, there is an increased risk of injury in
the event of the accident. Do not force contain-
ers that are too large into the cupholders; other-
wise, damage could result.<
In the center armrest
The cupholders are located in the center
console.
Attachable cupholder*
Attaching to the center console
Mount the cupholder onto the center console
so that it snaps into place.
Storing in the glove compartment
Insert the cupholder into the holder in the glove
compartment.

Sockets
In your BMW, when the engine is running or the
ignition is switched on, you can use electrical
devices such as a flashlight, car vacuum
cleaner, etc., up to approx. 200 watts at
12 volts, as long as one of the following sockets
is available. Avoid damaging the sockets by
attempting to insert plugs of unsuitable shape
or size.
Cigarette lighter socket*
To access the socket: take the cigarette lighter
out of the socket.
Under the center armrest
External audio device, refer to page104.
In the passenger footwell*

and fold the cover up.
Enlarging the cargo area
When the hardtop is closed you can enlarge the
cargo area:
To do so, press the cargo area partition 1
upward.
Before opening the hardtop, pull the cargo area
partition 1 down until it engages in both
guides2.
Before moving the hardtop, ensure that
there are no objects on or next to the
cargo area partition; otherwise, parts of the
hardtop may be damaged. Do not exceed the
maximum loading height; refer to the sticker in
the cargo area showing a line indicating the
maximum height. Do not use force to push
down the cargo area partition.<
The retractable hardtop can only be
opened if the cargo area partition is in its
lowermost position and engaged on both
sides.<
Through-loading opening
with integrated
transport bag*
Always secure transported skis or similar
objects with the ski support
*; otherwise,
they could endanger occupants during braking
maneuvers and swerving.<
The transport bag lets you transport up to two
pairs of standard skis safely and cleanly.
The transport bag can hold skis up to a length of
5.4 ft/1.70 m. When transporting skis that are
5.4 ft/1.70 m in length, the overall capacity of
the ski bag is reduced as the bag narrows.

Before driving into a car wash
General information on caring for your BMW
can be found on page208.
With Comfort Access and automatic
transmission
Insert the remote control into the ignition
switch.
The engine can be switched off when the selec-
tor lever is in position N. Refer also to page208.
With Comfort Access and 7-gear sport
automatic transmission with dual
clutch
Insert the remote control into the ignition
switch.
The engine can be switched off when the trans-
mission is in position N. Refer also to page209.
Cargo loading
To avoid loading the tires beyond their
approved carrying capacity, never over-
load the vehicle. Overloading can lead to over-
heating and increases the rate at which damage
develops inside the tires. This can ultimately
result in a sudden blowout.<
Make sure that no liquids are spilled or
leak from their containers in the cargo
area, as this could result in damage to the
vehicle.<
Always position and secure the cargo as
described so that it cannot endanger the
car's occupants, for example if sudden braking
or swerving is necessary.
Never exceed either the approved gross vehicle
weight or either of the approved axle loads, refer
to page228, as excessive loads can pose a
safety hazard, and may also place you in viola-
tion of traffic safety laws.
Heavy or hard objects should not be carried
loose inside the car, since they could be thrown
around, for example as a result of heavy braking,
sudden swerves, etc., and endanger the occu-
pants.<
Determining loading limit
1.Locate the following statement on your
vehicle's placard
*:
The combined weight of occupants
and cargo should never exceed
XXX kg or YYY lbs. Otherwise, overloading
can result in damage to the vehicle and
unstable driving conditions.<
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 capacity.
For example, if the YYY amount equals
1,400 lbs and there will be five 150 lbs
passengers in your vehicle, the amount of
available cargo and luggage load capacity
is 650 lbs:
1,400 lbs minus 750 lbs = 650 lbs
5.Determine the combined weight of luggage
and cargo being loaded on the vehicle. That
weight may not safely exceed the available
cargo and luggage load capacity calculated
in step 4.
6.If your vehicle will be towing a trailer, part of
the load from your trailer will be transferred
to your vehicle. Consult the manual for
transporting a trailer to determine how this
may reduce the available cargo and luggage
load capacity of your vehicle.

Things to remember when driving
116
Load
The permissible load is the sum of the occu-
pants' weights and the weight of the cargo. The
greater the weight of the occupants, the less
cargo/luggage can be transported.
Stowing cargo
Cargo area
>Load heavier cargo as far forward as possi-
ble, directly behind the cargo area partition,
and as low as possible.
>Cover sharp edges and corners.
Before opening the hardtop, fold down
the cargo area partition. Make sure the
cargo area is loaded correctly; otherwise,
parts of the hardtop can be damaged, refer
to page38.<
Lateral storage shelf
When storing objects on the lateral stor-
age shelf, do not move both seats all the
way forward while moving them to their upper-
most position and leaning the backrests for-
ward. Otherwise, the seats could hit and dam-
age the seal on the windshield, the sun visor
and the headliner.<
Light and small objects can be stored on the lat-
eral storage shelf.
Securing cargo
Cargo area
Secure smaller and lighter items using retaining
straps, a cargo area net
* or draw straps*.
Lateral storage shelf
You can obtain cargo straps* from your BMW
center. Four lashing eyes are provided behind
the seats for attaching the cargo straps.
Adhere to the information included with the
