the risk of serious property damage as well as
personal injury.
<
Mobile communications devices in
vehicle
BMW discourages the use of 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 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 page
178 .
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.
<
Starting off
On slopes
The starting assistant enables starting off on
slopes virtually without rolling back.
1. Hold the vehicle with the footbrake.
2. Make sure that the handbrake is released.
3. Release the footbrake and immediately
drive off quickly.
The starting assistant holds the vehicle
for approx. 1 second 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. 1 second
and it begins to roll back.
<
Start off quickly on slopes. Do not hold
the vehicle on a hill by pressing the accel-
erator, but apply the footbrake or handbrake
instead. Otherwise overheating and heavy wear
can result in the area of the Sequential Manual
Transmission.
<
To protect the clutch of the Sequential Manual
Transmission from overheating, the starting-off
behavior is changed under heavy loading, e.g. a
rapid succession of starts on slopes. This can
be noticed from shaking during starting off.
On a slippery surface
1. Select program "P 400" of M Engine
Dynamic Control, refer to page
58 .
2. Gently press accelerator pedal to prevent
wheels from spinning when starting off.
