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.

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 
high temperatures, brake wear and possibly 
even brake failure.

<

You can increase the engine's braking effect by 
shifting down, all the way to first gear if neces-
sary. This strategy helps you avoid placing 
excessive loads on the brake system. Down-
shifting in manual mode of the automatic trans-
mission, refer to page

Never drive with the clutch held down, 
with the transmission in idle or with the 

engine switched off; otherwise, engine braking 
action will not be present or there will be no 
power assistance to the brakes or steering.
Never allow floor mats, carpets or any other 
objects to protrude into the area around the 
pedals, otherwise pedal function could be 
impaired.

<

Limited vehicle use, extended periods with the 
vehicle parked or in storage, and operating con-
ditions in which braking is restricted to gentle, 
low-pressure applications will all increase the 
tendency for corrosion to form on the rotors and 
contamination to accumulate on the brake 
pads. This occurs because the minimal pres-
