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 can be transported.
Stowing cargo
>Load heavy cargo as far forward as possi-
ble, directly behind the luggage compart-
ment partition, and as low as possible
>Cover sharp edges and corners.
To avoid damaging the rear of the back-
rest or the rear interior trim panel, do not
stow heavy cargo or cargo with sharp edges
and corners behind the seats.
In addition, large and bulky cargo stowed
behind the seats may prevent the backrest from
engaging properly. Therefore, ensure that the
backrest is securely locked and if necessary,
move the seat forward, refer to page28.
Always position and secure the load as
described above; otherwise, it can endanger
the passengers, for example during braking or
evasive maneuvers.
Do not exceed the approved gross vehicle
weight or the specified maximum axle loads.
Refer to page103. Otherwise the vehicle's
operating safety is no longer assured and you are in violation of the law.
Do not stow heavy or hard objects in the pas-
senger compartment without first securing
them. Otherwise they would be thrown around
during braking and evasive maneuvers and
would endanger the occupants.<
Convertible top compartment
With the convertible top closed, you can
enlarge the luggage compartment, refer
to page19.
It is advisable to always fold down the covertible
top compartment panel as soon as you have
removed your cargo from the luggage compart-
ment. This way, you can be sure that you can
always operate the convertible top at any time.
Conversely, when the convertible top is closed,
raise the convertible top compartment panel
before stowing your cargo in the luggage com-
partment to avoid any damage to the convert-
ible top compartment or your load.
Do not stow any items on the convertible top
compartment panel since the convertible top
could be damaged while it is opening.<
If you stow cargo behind the seats of your
BMW:
>Only stow light objects such as clothing,
etc.
>Do not pile objects higher than the top edge
of the backrests.

2.Open the cap of the expansion tank by turn-
ing it slightly counterclockwise to allow
accumulated pressure to escape, then
open completely
3.The coolant level is correct when the upper
end of the red float is at least even with the
upper edge of the filler neck but no more
than 3/4 in/2 cm above it, that is up to the
second mark on the float. Refer also to the
schematic diagram next to the filler neck
4.Slowly add coolant, if necessary, until the
correct level is reached; do not overfill
5.Turn the cap clockwise until it is tightly
closed

the parking brake is not engaged:
Stop the vehicle immediately.
The brake fluid level in the reservoir is too low.
At the same time, you may notice that brake

pads have worn down to the minimum
safe limit. Have the brake pads
replaced as soon as possible.
For your own safety: use only brake pads
which BMW has approved for your spe-
cific vehicle model. BMW cannot evaluate non-
approved brake pads to determine if they are
suitable for use, and therefore cannot guaran-
tee the operating safety of the vehicle in the
event of their use.<

Charge the battery in the vehicle only when the
engine has been switched off. Terminals, refer
to Jump starting, page97.
Battery disposal
After changing a battery, have the used
battery disposed of by your BMW center
or bring it to a recycling point. Maintain the bat-
tery in an upright position for transport and stor-
age. Secure the battery against tilting when
transporting.<
Power loss
After a temporary power loss, e.g. due to a dis-
charged battery, some equipment will be lim-
ited in its use and must be reinitialized. Individ-
ual settings are also lost and must be reset:
>Seat memory

cause a fire in the vehicle as a result of circuit
overload.<

Giving and receiving assistance
98 positive terminal of the battery or to an aux-
iliary jump-starting terminal of the vehicle to
be jump-started.
Your BMW is equipped with a special nut,
refer also to the engine compartment over-
view on page85
3.With the– jumper cable, connect the nega-
tive terminals of both vehicles.
To do this:
Attach one cable clamp to the negative bat-
tery terminal or to a suitable ground on the
engine or body work of the support vehicle.
Attach the second cable clamp to the nega-
tive battery terminal or to a suitable ground
on the engine or body work of the vehicle to
be jump-started.
Starting the engine
1.Start the engine of the support vehicle and
let it run for several minutes at a slightly ele-
vated engine idle speed
2.Start the engine of the other vehicle as
usual.
If the first start attempt is not successful,
wait a few minutes before another attempt
in order to allow the discharged battery to
recharge
3.Allow the engines to run for several minutes
4.Then disconnect the jumper cables in
reverse sequence
5.Depending on the cause of the fault, have
the battery checked and recharged.

Towing and tow-starting the
vehicle
Using the towing eyelet
The screw-in towing eyelet is stored in the
onboard tool kit; be sure that it remains in the
vehicle at all times. It can be attached at the
front or rear of your BMW.
Observe the following instructions in
order to avoid damaging the towing eye-
let or the vehicle: use only the towing eyelet
supplied with the vehicle, and screw it in firmly
until it stops. Use the towing eyelet for towing
on paved roads only. Avoid subjecting the tow-
ing eyelet to lateral loads, e.g. do not lift the
vehicle using the towing eyelet.<
Access to the threaded socket
Press out the cover with a screwdriver inserted
in the recess at the top.
Being towed
Make sure that the ignition key is in posi-
tion 1, because the steering lock could
otherwise engage and the vehicle could no
longer be steered. There is no power assist
while the engine is off. Therefore, you will need
to exert more force to brake and steer the vehi-
cle.<
Turn on the hazard warning flashers, if required
by national regulations. If the electrical system
has failed, clearly identify the vehicle being
towed, e.g. by placing a sign or a warning trian-
gle in the rear window.
