Mobile communications devices in
vehicle

BMW advises against using mobile com-
munications devices, e.g. mobile phones,

inside the vehicle without a direct connection
to an external antenna. Otherwise, the vehicle
electronics and mobile communications device
can interfere with one another. In addition, there
is no assurance that the radiation emitted dur-
ing transmission will be conveyed out of 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 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, also refer to Mini-
mum tire tread on page

.

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
vehicle's engine, electrical systems and trans-
mission 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.

Start off quickly on slopes. Do not hold
the vehicle on a hill by applying the throt-

tle, but engage the handbrake instead. Other-
wise overheating can occur in the transmission
region.

<

Starting assistant

The starting assistant enables you to start off
conveniently on slopes. The parking brake is
not required for this purpose.

1.

Hold the vehicle with the footbrake.

2.

Release the footbrake and immediately
drive off quickly.

The starting assistant holds the vehicle
for approx. 2 seconds after releasing the

footbrake. Depending on the load, the vehicle
may also roll back slightly during this time.
After releasing the footbrake, immediately start
quickly; otherwise, the starting assistant no
longer holds the vehicle after approx. 2 seconds
and it begins to roll back.

<

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 at the brake pedal combines with
sounds from the hydraulic circuits to indicate to
the driver 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 driving on wet roads or 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 endan-
ger 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.

Hills

To prevent overheating and thus reduced
efficiency of the brake system, downshift

to a gear in which only minimal brake applica-
tions are needed when descending long or
