Portable phone in the vehicle
BMW discourages the use of mobile
communications devices, e. g. portable
phones, inside the vehicle without a direct con-
nection to an outside antenna. Otherwise, the
vehicle electronics and mobile communication
device can influence one another. In addition,
there is no assurance that the radiation which
results from transmission will be dissipated
from the vehicle interior.<
Interior and exterior mirrors, automatic
dimming feature*
This feature is controlled by two photocells in
the inside rearview mirror. One is integrated into
the glass of the mirror, while the other is located
at an offset position on the rear of the mirror
housing.
For trouble-free operation, keep the photocells
clean and do not cover the area between the
interior rearview mirror and the windshield. Do
not attach stickers of any kind to the windshield
in front of the mirror, either.
Hydroplaning
When driving on wet or slushy roads,
reduce road speed. If you do not, a wedge
of water can form between tires and road sur-
face. This phenomenon is referred to as hydro-
planing, and is characterized by a partial or
complete loss of contact between the tires and
the road surface, ultimately undermining your
ability to steer and brake the vehicle.<
The risk of hydroplaning increases as the tread
depth of the tires decreases, refer also to Mini-
mum tire tread on page173.
Driving through water
Do not drive through water on the road if it
is deeper than 1 ft/30 cm, and then only at
walking speed at the most. Otherwise, the vehi-
cle's engine, the electrical systems and the
transmission may be damaged.<
Using handbrake on inclines
On inclines, do not hold the vehicle with
the clutch; use the handbrake. Otherwise
greater clutch wear will result.<
SMG Sequential manual transmission
Start off quickly on slopes. Do not hold
the vehicle on a hill by pressing the accel-
erator, but apply the handbrake instead. Other-
wise overheating can occur in the transmission
region.<
Braking safely
Your BMW is equipped with ABS as a standard
feature. In situations that require it, it is best to
brake with full force. Since the vehicle maintains
steering responsiveness, you can still avoid
possible obstacles with a minimum of steering
effort.
Pulsation of the brake pedal, combined with
sounds from the hydraulic circuits, indicate that
ABS is in its active mode.
Do not drive with your foot resting on the
brake pedal. Even light but consistent
pedal pressure can lead to high temperatures,
brake wear and possibly even brake failure.<
Driving in wet conditions
When roads are wet or there is heavy rain,
briefly exert gentle pressure on the brake pedal
every few miles. Monitor traffic conditions to
ensure that this maneuver does not endanger
other road users. The heat generated in this
process helps dry the pads and rotors to ensure
that full braking efficiency will then be available
when you need it.

Things to remember when driving
108
Hills
To prevent overheating and the resulting
reduced efficiency of the brake system,
drive long or steep downhill gradients in the
gear in which the least braking is required. Even
light but consistent pedal pressure can lead to
high temperatures, brake wear and possibly
even brake failure.<
You can further enhance the engine's braking
action by selecting a lower gear in the automatic
transmission's manual mode, downshifting as
far as first gear on extremely steep stretches,
refer to page56. This strategy helps you avoid
placing excessive loads on the brake system.
Never drive with the clutch pressed or
allow the vehicle to coast with the trans-
mission in Neutral – or with the engine switched
off – there is no engine braking when the trans-
mission is in Neutral, and no power-assist for
brakes and steering when the engine is not run-
ning.
Never allow floor mats, carpets or any other
objects to protrude into the area around the
accelerator and brake pedals and obstruct their
movement.<
Corrosion on brake rotors
When the vehicle is driven only occasionally,
during extended periods when the vehicle is not
used at all, and in operating conditions where
brake applications are less frequent, there is an
increased tendency for corrosion to form on
rotors, while contaminants accumulate on the
brake pads. This occurs because the minimum
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 in the air conditioner sys-
tem during operation, and then exits under the
vehicle.
Traces of condensed water under the
vehicle are therefore normal
.
Before driving into a car wash
To prevent the exterior mirrors on this vehicle
from being damaged, always fold them in by
hand before entering an automatic car wash.
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. The ultimate result
can assume the form of a sudden blow-out.<
Determining loading limit
1.Locate the following statement on your
vehicle's placard
*:
The combined weight of occupants
and cargo should never exceed
XXX lbs. or YYY kg. Otherwise, this could
damage the vehicle and produce unstable
vehicle operating 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 lbs. or YYY kg.
4.The resulting figure equals the available
amount of cargo and luggage load capacity.
For example, if the XXX amount equals
1,400 lbs. and there will be five 150 lb. pas-
sengers in your vehicle, the amount of avail-
able 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 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.
>For very heavy cargo when the rear seat is
not occupied, secure each safety belt in the
opposite buckle.
Securing cargo
>Use the luggage net*, luggage straps, 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 this lashing equipment, refer
to illustration.
>Please observe the special instructions
supplied with the heavy-duty cargo straps.
Always position and secure the load as
described above. If you do not, it can
endanger the passengers during braking or
evasive maneuvers.
Never exceed either the approved gross vehicle
weight or either of the approved axle loads, refer
to page198, as excessive loads can pose a
safety hazard, and may also place you in viola-
tion of traffic 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 maneuvers.<

Tollroads are avoided where possible
>"Avoid ferries"
Ferries are avoided where possible
To exit from the menu:
Select the arrow and press the controller.
The route is planned according to fixed rules.
The type of road is taken into account, e.g.
whether it is a highway or a winding road. The
road types are stored on the navigation DVD.
As a result, the routes recommended by the
navigation system may not always be the same
ones that you would choose based on personal
experience.
You can change the choice of route as often as
you like while entering the destination and
whenever the destination guidance is active.Word matching principle
The system supports the word matching princi-
ple to make it easier for you to enter the names
of streets or towns. The system runs ongoing
checks, comparing your destination entries
with the data stored on the navigation DVD as
the basis for instant response. The user bene-
fits include:
>Names of specific locations can also vary
from the official versions if you are using a
spelling that is customary in another coun-
try.
Example:
Instead of "München", you can also enter
the English spelling "Munich" or the Italian
spelling "Monaco".
>When you are entering the names of towns
and streets the system will complete them
automatically as soon as enough letters are
available to ensure unambiguous identifica-
tion.
>The system only accepts name entries
beginning with letters that are stored on the
navigation DVD. The system will not accept
nonexistent names and addresses.

approved units – these differences could lead to
body contact, and with it the risk of severe acci-
dents. If non-approved wheels and tires are
used, BMW cannot evaluate their suitability,
and therefore cannot be held liable for driving
safety.<
You can inquire about the right wheel/tire com-
bination at your BMW center.
The correct combination of wheels and tires is
another vital factor in ensuring reliable opera-
tion of various vehicle systems such as ABS
and DSC.
To maintain good handling and vehicle
response, use only tires of a single tread config-
uration from a single manufacturer. After a flat
tire, have the original wheel and tire combina-
tion remounted on the vehicle as soon as possi-
ble.
Recommended tire brands
BMW tests certain tire brands for each tire size,
classifies them as road-safe and approves
them. Consult your BMW center for more infor-
mation.
Observe any country-specific regulations, e.g.
on making a corresponding entry in the vehicle
documents.
The factory-mounted tires have been specially
selected to provide optimized performance
when installed on yo ur vehicle; if pro perly cared
for, they will provide a combination of safety and
excellent ride comfort.
Run-flat tires
When mounting new tires or changing from
summer tires to winter tires or vice versa, use
run-flat tires because there is no spare tire in
case of a flat. Your BMW center will be glad to
advise you.
For safety reasons, BMW recommends
that you do not have damaged run-flat
tires repaired; they should be replaced.<
Special characteristics of winter tires
BMW recommends winter tires for use in cold
winter driving conditions. Although all-season
M+S tires provide better winter traction than
summer tires, they generally fail to provide the
same levels of cold-weather performance as
winter tires.
Pay attention to speed
Do not exceed the maximum permissible
speed for the winter tires, otherwise tire
damage may occur, which can result in 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, fine-link snow chains.
Use is only permitted in pairs, with winter tires
on the rear wheels.
Observe the manufacturer's instructions when
mounting snow chains. Do not exceed a speed
of 30 mph/50 km/h with the chains mounted.
After snow chains are mounted, do not
initialize the Flat Tire Monitor.
When driving with snow chains, it can be useful
to activate the DTC temporarily, refer to
page78.<

3.The coolant level is correct when the cool-
ant level is between the MIN and MAX
marks, refer to the diagram adjacent to the
filler neck.
4.If the coolant is low, slowly add coolant up to
the specified level – do not overfill.
5.Turn the cap until there is an audible click.
6.Have the reason for the coolant loss elimi-
nated as soon as possible.

For your own safety: use only brake pads
that BMW has approved for the corre-
sponding vehicle model. As BMW cannot
assess the suitability of other brake pads for
use on your vehicle, we are unable to assume
continued responsibility for the vehicle's oper-
ating safety if non-approved pads are
installed.<
