Things to remember when driving

Things to remember when driving
Breaking-in
Moving parts need time to adjust to one
another. To ensure that your vehicle continues
to furnish optimized economy of operation
throughout an extended service life, we request
that you devote careful attention to the follow-
ing information.
Engine and differential
Always obey all official speed limits.
Up to 1,200 miles/2,000 km
Drive with changing engine and vehicle speeds,
but do not exceed:
4500 rpm or 100 mph/160 km/h
Avoid full-throttle operation and use of the
transmission's kick-down mode during these
initial miles.
After 1,200 miles/2,000 km
The engine and vehicle speed can gradually be
increased.
Tires
Due to technical factors associated with their
manufacture, tires do not achieve their full trac-
tion potential until after an initial break-in
period. Therefore, drive reservedly during the
first 200 miles/300 km.
Brake system
Brakes require an initial break-in period of
approx. 300 miles/500 km to achieve optimized
contact and wear patterns between brake pads
and rotors.
Following component replacements
Follow the break-in sequence again if compo-
nents addressed above must be replaced again
during subsequent driving.
General driving notes
Closing luggage compartment lid
Operate the vehicle only when the lug-
gage compartment lid is completely
closed. Otherwise, exhaust fumes could pene-
trate into the passenger compartment.<
If special circumstances should make it abso-
lutely necessary to operate the vehicle with the
luggage compartment lid open:
1.Close all windows and the glass sunroof.
2.Adjust the automatic climate control's
blower to supply a high rate of airflow, refer
to page106.
Hot exhaust system
As in all vehicles, extremely high temper-
atures are generated in the exhaust sys-
tem. Do not remove the heat shields installed
adjacent to it, and never apply undercoating to
them. When driving, standing at idle, and park-
ing, take care to avoid possible contact
between the hot exhaust system and any highly
flammable materials such as hay, leaves, grass,
etc. Such contact could lead to a fire, accompa-
nied by the risk of serious property damage and
personal injury.<
Mobile communications devices in
vehicle
BMW does not recommend using mobile
communications devices, e.g. mobile
phones, inside the vehicle without a direct con-
nection to an outside antenna. Otherwise, the
vehicle electronics and mobile communications
device can interfere with each other. In addition,
there is no assurance that the radiation which
results during transmission will be discharged
from the vehicle interior.<

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 tires and
road surface, ultimately undermining your abil-
ity to steer and brake the vehicle.<
Driving through water
Only drive through water with a maximum
depth of 1 ft/30 cm and then, at no more
than walking speed. Otherwise, you run the risk
of damaging the vehicle's engine, electrical sys-
tems, and transmission.<
Safe braking
Your BMW is equipped with ABS as standard
equipment. In situations that require it, it is best
to apply the brakes fully. Since the vehicle
maintains steering responsiveness, you can
nevertheless avoid possible obstacles with a
minimum of steering effort.
Pulsation at the brake pedal combines with
sounds from the hydraulic circuits to indicate to
the driver that ABS is in its active mode.
Driving in wet conditions
When driving in wet conditions and in heavy
rain, it is a good idea to apply light pressure to
the brake pedal every few miles. Monitor traffic
conditions to ensure that this maneuver does
not endanger other road users. The heat gener-
ated helps dry the pads and rotors to ensure
that full braking efficiency will then be available
when you need it.
Hills
To prevent overheating and reduced effi-
ciency of the brake system, drive long or
steep downhill grades in the gear that requires
the least amount of braking. Otherwise, even
light but consistent pedal pressure can lead to
high temperatures, brake wear, and possibly
even failure of the brake system. 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 page63. This strategy helps you avoid
placing excessive loads on the brake system.
Do not drive in idle or with the engine
switched off; otherwise, there will be no
engine braking action or power-assist for the
brakes and steering.
Never allow floor mats, carpets or any other
objects to protrude into the area of movement
of the pedals and impair their operation.<
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 minimal
pressure that must be exerted by the pads dur-
ing 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 vehicle is parked
Condensation forms in the automatic climate
control during operation, and then exits under
the vehicle. Traces of condensed water under
the vehicle are therefore normal.
Before driving into a car wash
1.Fold in the exterior mirrors, refer to page50;
otherwise, they could be damaged due to
the width of the vehicle.
To permit the vehicle to roll, follow the
instructions on page58.
2.Release the parking brake, especially when
you have activated Automatic Hold. Refer to
page59.

Securing cargo
>Use the luggage net* or securing straps to
secure small and lightweight luggage and
cargo.
>Heavy-duty straps
* for securing larger and
heavier objects are available at your BMW
center. Four lashing eyes for attaching
these heavy-duty straps are provided in the
luggage compartment, refer to illustration.
>Please follow the special instructions sup-
plied with the heavy-duty straps.
Always position and secure the load as
described above. If you do not, it can
endanger the passengers, for example during
braking or evasive maneuvers.
Attach heavy-duty straps only to the lashing
eyes, refer to illustration, otherwise, the heavy-
duty straps could come loose or the vehicle
could be damaged.
Never exceed either the approved gross vehicle
weight or either of the approved axle loads, refer
to page228, as excessive loads can impair the
operational safety of the vehicle and may also
put you in violation of highway safety laws.
You should never transport unsecured heavy or
hard objects in the passenger compartment, as
they could fly around and pose a safety hazard
to the vehicle's occupants during abrupt brak-
ing or evasive maneuvers .<
Roof-mounted luggage rack*
A special rack system is available as an option
for your BMW. Please comply with the precau-
tions included with the installation instructions.
Anchorage points
The anchorage points are located inside the
door openings.
Loading roof rack
Because roof racks raise the vehicle's center of
gravity when loaded, they have a major effect on
its 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 this information under Weights on
page228.
The roof load must be uniformly distributed and
should not be too large in area. Always load the
heaviest pieces on the bottom. Be sure that
adequate clearance is maintained for raising the
glass sunroof, and that objects do not project
into the opening path of the luggage compart-
ment lid.
Secure roof-mounted cargo correctly and
securely to prevent it from shifting or falling off
as you drive.
Drive smoothly. Avoid sudden acceleration and
braking maneuvers. Take corners gently.
