Driving notes
Parking the vehicle
Condensation forms in the air conditioner
system during operation, which then exits
under the vehicle. Traces of condensed
water on the ground underneath the vehi-
cle are thus normal.
Brakes
Do not drive with your foot resting on
the brake pedal. Even light but con-
sistent pedal pressure can lead to high
temperatures, brake wear and possibly
even brake failure.
Hydroplaning
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 phenomenon
can lead to partial or complete loss of trac-
tion, vehicle control and braking effective-
ness.<
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. Otherwise,
the vehicle's engine, the electrical systems
and the transmission may be damaged.<
High temperatures
High temperatures occur with every
vehicle equipped with a catalytic con-
verter. Heat shields are installed adjacent
to some sections of the exhaust system.
Never remove these shields; do not apply
undercoating to their surfaces. When driv-
ing, standing at idle and parking the vehi-
cle, take care to avoid contact between the
hot exhaust system and flammable materi-
als, e.g. hay, leaves, grass, etc. Such con-
tact could lead to a fire, resulting in serious
personal injury and property damage.<
Brake system
Indicator lamp
The indicator lamp lights up
although the parking brake is not
engaged:
Check the brake fluid level. It is very impor-
tant that you follow the instructions on
page 85 before driving on.
Disc brakes
Corrosion
Limited vehicle use, extended periods with
the vehicle parked or in storage, and oper-
ating conditions in which braking is
restricted to gentle, low-pressure applica-
tions will all increase the tendency for cor-
rosion to form on the rotors and contamina-
tion to accumulate on the brake pads. This
occurs because the minimal pressure
which must be exerted by the pads to clean
the rotors by brake applications is not
reached.
If the brake rotors are corroded, they will
tend to respond to braking with a pulsating
effect which even extended application will
fail to cure.
Wet roads
When driving in heavy rain and on wet
roads, it is useful to apply light pressure
to the brake pedal every few miles. Watch
traffic conditions to ensure that this maneu-
ver does not endanger other road users.
The resulting heat dries the brake rotors
and brake pads. Immediate braking control
is then available if necessary.
Inclines
Extended or steep mountain descents
should be driven in the gear or drive posi-
tion in which only minimal periodic brake
application is required. This helps avoid
placing excessive loads on the brake sys-
tem. Observe the maximum allowable
engine speed when doing so; refer to
page 48.

allow accumulated pressure to escape,
then open completely
2.The coolant level is correct when the
upper end of the red float is at least
even with the upper edge of the filler
neck but no more than 3/4 in/2 cm
above it, that is up to the second mark
on the float. Refer also to the schematic
diagram next to the filler neck
3.If necessary, add coolant. Slowly add
coolant until the correct level is
reached; do not overfill.
Comply with the applicable environ-
mental laws regulating the disposal of
antifreeze with corrosion inhibitor.<
Brake fluid
Indicator lamp
The brake warning lamp lights up
red when the parking brake is not
engaged: the brake fluid level is too
low, refer to page 69.
The brake warning lamp for Cana-
dian models lights up red when the
parking brake is not engaged: the
brake fluid level is too low, refer to page 69.
Brake fluid, refilling
Brake fluid loss may result in extended
brake pedal travel. If this occurs, also refer
to the notes on page 69.
Brake fluid is hygroscopic, that is, it
absorbs moisture from the air over
time.
In order to ensure the brake system's
safety and reliability, have the brake fluid
changed every two years by a BMW center.
Refer also to page 49 and the Service Man-
ual.
Brake fluid is toxic and damages the vehi-
cle's paint. You should always store it in the
closed original container and in a location
inaccessible to children.
Do not spill the fluid and do not fill the brake
fluid reservoir beyond the MAX mark. The
brake fluid could ignite upon contact with
hot engine parts and cause serious
burns.<
Comply with the applicable environ-
mental laws regulating the disposal of
brake fluid.<
Brake fluid level
Low brake fluid level in the reservoir com-
bined with extended pedal travel may indi-
cate a defect in one of the brake system's
hydraulic circuits.
BMW recommends that you proceed
to the nearest BMW center. Higher
brake application pressure may be neces-
sary under these conditions, and braking
distances may be significantly longer.
Please remember to adapt your driving
style accordingly.<
