etc. Such contact could lead to a fire, and with it
the risk of serious property damage as well as
personal injury. Do not touch hot exhaust tail
pipes. Otherwise there is a risk of burns.<
ensure that this maneuver does not endanger
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.
Hydroplaning
Hills
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.<
To prevent overheating and the resulting
reduced efficiency of the brake system,
drive long or steep downhill gradients in the
gear in which the least braking is required. Even
light but consistent pressure on the brake can
lead to high temperatures, brake wear and pos-
sibly even brake failure.<
The risk of hydroplaning increases as the tread
depth of the tires decreases, refer also to Mini-
mum tire tread on page 206.
Sequential Manual Transmission: do not
drive in idle or with the engine switched
off, otherwise there will be no engine braking
action or support of the braking force and steer-
ing.
Driving through water
Manual transmission: do not drive with the
clutch depressed, in idle or with the engine
switched off, otherwise there will be no engine
braking action or support of the braking force
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.<
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.<
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.
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 minimum
pressure which must be exerted by the pads
during brake applications to clean the rotors is
not reached.
The pulsing of he brake pedal indicates that the
ABS is controlling braking.
In certain braking situations the perforated
brake rotors can cause operating noises which,
however, have not effect on the performance
and operating safety of the brake system.
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.<
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.
Driving in wet conditions
When vehicle is parked
When roads are wet or there is heavy rain,
briefly exert gentle pressure on the brake pedal
every few miles. Monitor traffic conditions to
Condensation forms in the air conditioner sys-
tem during operation, and then exits under the
