Load
The permitted load is the total of the weight of
occupants and cargo/luggage. The greater the
weight of occupants, the less cargo/luggage
can be transported.
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 luggage
and cargo.
>Heavy-duty cargo straps
* for securing
larger and heavier objects are available at
your BMW center. Four lashing eyes
mounted 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, otherwise it may
present a danger to passengers during braking
or evasive maneuvers.
Never exceed either the approved gross vehicle
weight or either of the approved axle loads, refer
to page192, as excessive loads can pose a
safety hazard, and may also place you in viola-
tion of freeway safety laws.
You should never transport heavy or hard
objects unsecured in the passenger compart-
ment, as they could fly around and pose a safety
hazard to the vehicle's occupants during abrupt
braking or evasive maneuver.<

Run-flat tires
If you switch from summer to winter tires, or
vice versa, use run-flat tires, refer to page172,
as in the event of a flat tire there is no spare tire
available. Your BMW center will be glad to
advise you.
Watch speed
Observe the permissible maximum speed
for the respective winter tires, as other-
wise tire damage and occur and cause acci-
dents.<
Storage
Always store wheels and tires in a cool, dry
place with as little exposure to light as possible.
Always protect tires against all contact with oil,
grease and fuels. Do not exceed the maximum
tire inflation pressure indicated on the side wall
of the tire.
Snow chains*
BMW only tests certain fine-link snow chains,
classifies them as road-safe and approves
them. Consult your BMW center for more infor-
mation. BMW recommends using these
approved snow chains. These snow chains are
approved exclusively for use in pairs on the rear
wheels with the tire size:
>245/50 R 17 Y
>245/45 R 18 Y
Observe the chain manufacturer's instructions
when mounting snow chains. Do not exceed a
vehicle speed of 30 mph/50 km/h with the
chains mounted.
Do not initialize the Flat Tire Monitor after
mounting snow chains.
When you are driving with snow chains, it can
be beneficial to switch off DTC briefly, refer to
page82.<

Brake system
Malfunction
Brake fluid
The warning lamp lights up in red
in spite of the handbrake being
released; a message appears on the
Control Display.
Stop the vehicle immediately.
The brake fluid in the reservoir has fallen to
below the minimum level. At the same time, a
significantly longer brake pedal path may be
noticeable. Have the system checked immedi-
ately by a BMW center.
Warning lamp for Canadian models.
When you continue driving, an increased
brake pedal path can be necessary, and
significantly longer braking distances might be
required. Please adapt your driving style
accordingly.<
Brake pads
The warning lamp lights up in red
in spite of the handbrake being
released; a message appears on the
Control Display. The brake pads have reached
their minimum pad thickness. Have the brake
pads replaced as soon as possible.Warning lamp for Canadian models.
For your own safety: use only brake pads
that BMW has approved for your particu-
lar vehicle model. As BMW cannot assess the
suitability of other brake pads for use on your
vehicle, BMW is unable to assume continued
responsibility for the vehicle's operating safety
if non-approved pads are installed.<

OBD Socket
The Onboard Diagnostics OBD interface
socket is located on the left of the driver's side
under the instrument panel and under a cover.
The cover has the letters OBD on it.
The purpose of the OBD system is to ensure
proper operation of the emission control sys-
tem for the vehicle's lifetime. The system mon-
itors emission-related components and sys-
tems for deterioration and malfunction.
An illuminated indicator lamp informs
you of the need for service, not of the
need to stop the vehicle. However, the
systems should be checked by your BMW cen-
ter at the earliest possible opportunity.
Display of the previously described
malfunction on Canadian models.
Under certain conditions, the indicator
lamp will blink or flash. This indicates a rather
severe level of engine misfire. When this
occurs, you should reduce speed and consult
the nearest BMW center as soon as possible.
Severe engine misfire over only a short period
of time can seriously damage emissions control
components, especially the catalytic converter.
When the fuel filler cap is not properly
tightened, the OBD system can detect
the vapor leak and the indicator lamp will light
up. If the filler cap is subsequently tightened,
the indicator lamp should go out within a few
days.<
Event Data Recorders
Your vehicle may be equipped with one or more
sensing and diagnostic modules or a recording
device capable of recording or transmitting cer-
tain vehicle data or information. In addition, if
you have a Subscription Service Agreement for
the BMW Assist system, certain vehicle infor-
mation may be transmitted or recorded in order
to provide such services.
Care
Important information on care and maintenance
of your BMW is contained in the Caring for your
vehicle brochure.

compartment under the floor mat.
Wiper blade replacement
1.Fold the wiper arm out and grasp it firmly.
2.Press the locking tabs together while slid-
ing the wiper blade toward the front to dis-
engage it.
Lamps and bulbs
Lamps and bulbs make an essential contribu-
tion to driving safety. Therefore, exercise suffi-
cient care when handling them. If you are not
familiar with the specified procedures, have the
corresponding work carried out at your BMW
center.Never touch the glass on new bulbs
with your bare fingers, as even minute
amounts of contamination will burn into the
bulb's surface and reduce its service life. Use a
clean cloth, napkin etc., or hold the bulb by its
metal socket.<
You can obtain a selection of replacement bulbs
at your BMW center.
When working on the lighting system
you should always switch off the lights
affected to prevent short circuits.
To avoid possible injury or equipment damage
when replacing bulbs, observe any instructions
provided by the bulb manufacturer.<
When performing maintenance on the head-
lamps, comply with the instructions in the sep-
arate Caring for your vehicle brochure.
In the case of bulbs where the replace-
ment is not described, please consult
your BMW center.<
Xenon lamps
The service life of these lamps is very long and
the probability of a failure is very low, provided
that they are not switched on and off an unusual
number of times. In the unlikely event that one
of these lamps should fail, you can continue
driving under poor visibility conditions by
switching on your fog lamps and proceeding
carefully, where allowed by law.
To avoid the risk of potentially fatal inju-
ries: owing to the extremely high voltages
at which these units operate, service work on
the xenon lighting system should only be car-
ried out by a BMW center.<
