cannot be ruled out that vehicle electronics and 
the mobile communications device interfere 
with one another. In addition, it is not ensured 
that the radio waves emitted during transmis-
sion are directed outside of the vehicle inte-
rior.

The automatic dimming feature of the interior 
and exterior mirrors

is controlled by two photo 

cells in the interior rearview mirror. In the Road-
ster, one is located in the mirror glass, see 
arrow. In the Coupe, it is located at the bottom 
of the mirror frame. The other photo cell is on 
the back of the mirror.
In order to ensure that the system functions 
correctly, keep the photocells clean, do not 
cover the area between the interior rearview 
mirror and windshield, and do not affix adhesive 
labels or stickers of any kind to the windshield 
directly in front of the mirror.

When driving on wet or slushy roads, 
reduce vehicle speed. If you do not, a 

wedge of water may form between the tires and 
the road surface. This situation, known as 
hydroplaning, means that the tire can com-
pletely lose contact with the road surface, so 
that neither the car can be steered nor the brake 
be properly applied.

<

The risk of hydroplaning increases with declin-
ing tread depth on the tires, refer also to Mini-
mum tread depth on page

.

Drive through water on the road only if it is 
not deeper than 1 ft/30 cm, and then only 

at walking speed at the most. Otherwise, the 
vehicle's engine, the electrical systems and the 
transmission may be damaged.

<

Make sure that the passenger compart-
ment does not become wet and that liq-

uids are transported in closed containers. 
Otherwise, moisture could penetrate and dam-
age electronic components inside the vehicle.

<

On inclines, keep the vehicle from rolling 
by using the parking brake rather than by 

slipping the clutch, which would lead to a high 
degree of clutch wear.

Your BMW is equipped with ABS as a standard 
feature. Applying the brakes fully is the most 
effective way of braking in situations in which 
this is necessary. 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.

When roads are wet or there is heavy rain, 
briefly exert gentle pressure on the brake pedal 
every few miles. Watch traffic conditions to 
ensure that this maneuver does not endanger 
other road users. The resulting heat dries the 
brake rotors and brake pads. Immediate braking 
force is then available if necessary.

To prevent overheating and, as a result, 
diminished braking effectiveness, drive 

down long or steep downhill grades in the gear 
that requires the least braking. Otherwise, even 
light but consistent pedal pressure can lead to
