tion options, refer to page 102. Parked-car ventilation
system

System operation is controlled using the
Control Display. You can set two different
times for the system to start.
The parked-car ventilation blows air into
the passenger compartment to lower inte-
rior temperatures.
The system remains on for 30 minutes. You
can also switch the system on and off
manually. Since the system uses a
substantial amount of electrical current,
you should refrain from activating it twice in
succession without allowing the battery to
be recharged in normal operation between
use.
The parked-car ventilation system is avail-
able for preprogrammed operation at
outside temperatures above approx. 50 7
(10 6) and for direct activation at any
temperature, but is not operational when
the vehicle is underway.
The air enters the passenger compartment
through the vent outlets in the instrument
panel, which can be adjusted for both
direction and airflow. These outlets must
be open for the system to operate.

Brake system Braking with ABS The best way to achieve optimal response
from the ABS is to apply maximum pres-
sure to the brake pedal during emergencyÐ
panic stops. Since the vehicle maintains
steering responsiveness, you can never-
theless avoid possible obstacles with a
minimum of steering effort.
Pulsation at the brake pedal combines with
sounds from the hydraulic circuits to indi-
cate 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.< Disc brakes
Driving in wet conditions While driving in wet conditions and 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 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. Hills You can retain full and unimpaired braking
efficiency by downshifting to a gear in
which only minimal brake applications are
needed when descending long or steep
downhill stretches.
You can further enhance the engine's
braking effect by selecting a lower gear in
the automatic transmission's manual
mode, downshifting as far as first gear on
extremely steep stretches, refer to
page 68. This strategy helps you avoid
placing excessive loads on the brake
system.
Corrosion When the vehicle is driven only occasion-
ally, 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
minimal pressure which must be exerted by
the pads during brake applications to clean
the rotors is not reached.
Should corrosion form on the brake rotors,
the brakes will tend to respond with a
pulsating effect that even extended appli-
cation will fail to cure.
Never allow the vehicle to coast with
the transmission in neutral Ð or with
the engine switched off; there is no engine
braking when the transmission is in neutral,
and no power-assist for brakes and
steering when the engine is not running.
Never allow floor mats, carpets or any other
objects to protrude into the area around the
accelerator and brake pedals and obstruct
their movement.< Brake pads
If the brake pad wear indicator lamp
appears in the Check Control,
accompanied by a text: please take
careful note of the additional information in
the Control Display panel.
Warning lamp for Canadian models.
The brake pads have reached their
minimum pad thickness. Have them
replaced at your BMW center as soon as
possible.
For your own safety: use only brake
pads that BMW has released for your
particular vehicle model. Because BMW
cannot assess the suitability of other brake
pads for use on your vehicle, we are unable
to assume continued responsibility for the
vehicle's operating safety if non-approved
pads are installed.<
