pressure which must be exerted by the pads
during brake applications to clean the rotors is
not reached.
Should corrosion form on the brake rotors, the
brakes will tend to respond with a pulsating
effect that even extended application will fail to
cure.
When the vehicle is parked
Condensation forms while the automatic cli-
mate control is in operation, and then exits
under the vehicle. Traces of condensed water
under the vehicle are therefore normal.
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. In some situations,
this can result in sudden loss of tire pressure.<
Avoid fluid spills in the cargo area as they
could damage the vehicle.<
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, damage to
the vehicle and unstable driving conditions
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 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.
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.

Things to remember when driving
120
Stowing cargo
Coupe
Convertible
>Position heavy objects as low and as far for-
ward as possible, ideally directly behind the
respective seat backrests.
>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 cargo
>Secure smaller and lighter items using draw
straps
*.
>Heavy-duty cargo straps
* for securing
larger and heavier objects are available at
your BMW center. To attach the cargo
straps, there are two lashing eyes on the
inside wall of the cargo area.
Comply with the information enclosed with
the load-securing devices.
Always position and secure the cargo as
described above, so that it cannot endan-
ger 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 page245, 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.
Only attach the cargo straps using the lashing
eyes shown in the illustration. Do not secure
cargo with the anchors for tether straps, refer to
page55, otherwise, these could be damaged.<
Coupe: roof-mounted
luggage rack*
A special rack system is available as an option
for your BMW. Comply with the directions given
in the installation instructions.
Mounting points
Fold open the cover.
Loading roof-mounted luggage rack
Because roof racks raise the vehicle's center of
gravity when loaded, they have a major effect on
vehicle handling and steering response.
You should therefore always remember not to
exceed the approved roof load capacity, the
approved gross vehicle weight or the axle loads
when loading the rack.
You can find the applicable data under Weights
on page245.
The roof load must be distributed uniformly and
should not be too large in area. Heavy items
should always be placed at the bottom. Be sure
