Heating and ventilation/Air conditioner
*
Air distribution
You can direct the flow of air
onto the windows , toward
the upper body and into the
footwell . All intermediate settings
are possible. In position , a small
volume of air is directed onto the
windows in order to keep them free of
condensation.
A "6 o'clock" position is recommended
as the normal operating setting.
Temperature
In order to increase the temper-
ature of the passenger compart-
ment, turn to the right (red). For
rapid heating, turn completely to the
right. Then select an interior tempera-
ture which is pleasant for you.
Air supply
You can select blower speeds
from 1 to 4. Both heating and
ventilation become more effec-
tive as the air supply rate is increased.
In position 0, the blower and the heater
are switched off.
Air conditioner
The air is cooled and dehumidi-
fied and Ð depending on the
temperature setting Ð warmed
again when the air conditioner system
is switched on. Depending on the
weather, the windshield may fog over
briefly when the engine is started.
Use the button to switch the air condi-
tioner off at outside temperatures
below approx. 41 7(+5 6). This will
help to prevent condensation from
forming on the windows.
If the windows fog over after switching
the air conditioner off, switch it back
on.
Condensation forms in the air
conditioner system during opera-
tion, which then exits under the vehicle.
Traces of condensed water of this kind
are thus normal.<
Recirculated-air mode
If there are unpleasant odors in
the outside air, you can tempo-
rarily block the supply of the
incoming air. The system then recircu-
lates the air currently within the vehicle.
If the windows fog over in the
recirculated-air mode, switch this
mode off and increase the air supply as
required.<

Draft-free ventilationYou can adjust the air outlets for the
upper body area completely for your
personal comfort:
Use the rotary dial 2 to open and close
the vent throughout an infinitely-vari-
able range. With the levers 1 you can
direct the airflow to the side, and up or
down by rotating the vent grill.
Set the outlets so that the air flows past
you and is not directed straight at you.367de224

Seat heating
*
The seat cushion and backrest can be
heated at ignition key position 2.
Press the buttons with the heating
symbols:
Rapid heating as long as the
button comes on brightly. Auto-
matic changeover to regular
heating.
Heating as long as the button
comes on brightly. Heating
switches off automatically.
To switch over while heating: press the
section of the button that is dimly lit.
To switch off early: press the section of
the button that is brightly lit.367de732

Catalytic converterThe catalytic converter reduces harmful
exhaust emissions.
It is designed for use with unleaded fuel
only.
Even minute quantities of lead would be
enough to permanently damage both
the catalytic converter and the system's
oxygen sensor.
To ensure efficient, trouble-free engine
operation and avoid potential damage:
>Be sure to comply with the scheduled
maintenance requirements
>Fill the fuel tank well before it is
empty
>If the engine runs roughly, shut it off
as soon as possible
>Tow-start the vehicle only when the
engine is cold. Tow-starting when the
engine is warm could cause unburned
fuel to ignite on the way to the cata-
lytic converter, resulting in significant
damage. It is better to start the vehicle
with an outside starting aid>Avoid any other situations in which
the fuel would not be (completely)
burned, for instance:
Frequent or consecutive extended
starting attempts or repeated starting
attempts when the engine fails to
start. (Shutting down and restarting
an engine which is running properly
does not present a problem.) Never
allow the engine to run with any of
the spark plug cables disconnected.Be sure to comply with the
instructions above to prevent
unburned fuel from reaching the cata-
lytic converter. Otherwise, the catalytic
converter could respond by over-
heating, leading to serious damage.
Extreme temperatures occur at the
catalytic converter on this and every
catalyst-equipped vehicle. Heat shields
are installed adjacent to some sections
of the exhaust system. Never remove
these shields; do not apply under-
coating to their surfaces.
When driving, standing while the engine
is idling, or when parking, be careful to
avoid contact between the hot exhaust
system and easily-flammable materials
(hay, dry grass, leaves, etc.). Such
contact could cause a fire, resulting in
personal injuries and property
damage.<

Disc brakes Brake system Should engine braking prove inade-
quate, you should still avoid extended,
continuous braking. Instead, decelerate
the vehicle with increased pressure on
the brake pedal (watch for following
traffic), release the pedal and then
repeat the brake application (staggered
braking). This staggered braking tech-
nique allows the brakes to cool in the
intervals between active braking
phases, preventing overheating and
ensuring that full braking capacity
remains available at all times.
Do not coast with the clutch
depressed or with the transmis-
sion or selector lever in Neutral. Do not
coast with the engine switched off. The
engine provides no braking effect when
the clutch is depressed and there is no
power-assist for braking or steering
when the engine is not running.
Never allow floor mats, carpets or any
other objects to protrude into the area
around the accelerator, clutch and
brake pedals and obstruct their move-
ment.<
Brake fluid level
The warning lamp for the
hydraulic brake system comes
on:
The brake fluid level is too low in
the reservoir (refer to page 126).
If the brake fluid level is too low
and brake pedal travel has become
noticeably longer, there may be a
defect in one of the two brake system's
hydraulic circuits.
Proceed to the nearest BMW
center. Higher brake application
pressure may be necessary under these
conditions, and braking distances may
be significantly longer. Please
remember to adapt your driving style
accordingly.<
Brake pads
The warning lamp for the brake
pads comes on:
The brake pads have reached
their minimum pad thickness. Proceed
to the nearest BMW center as soon as
possible to have the pads replaced.
For your own safety: use only
brake pads that BMW has
approved for your specific vehicle
model. BMW cannot evaluate non-
approved brake pads to determine if
they are suited for use, and therefore
cannot ensure the operating safety of
the vehicle in the event of their use.<

Tire condition Tire replacementmoderate speeds and with only small
amounts of water on the road.
Never continue driving on a
deflated (flat) tire. A flat tire greatly
impairs steering and braking response,
and can lead to complete loss of
control over the vehicle.
Avoid overloading the vehicle so that
the permitted load on the tires is not
exceeded. Overloading causes over-
heating and damage inside the tires.
The ultimate result can assume the
form of a sudden air loss.
Unusual vibrations encountered during
normal vehicle operation can indicate a
flat tire or some other vehicle malfunc-
tion. The type of problem can be
caused by contact with curbs, etc. This
is also true for irregularities in the
vehicle's handling characteristics, such
as a pronounced tendency to pull to the
left or right. Should this occur, respond
by immediately reducing your speed.
Proceed carefully to the nearest BMW
center or professional tire center, or
have the vehicle towed in to have it, its
wheels and tires inspected.
Tire damage (up to and including
sudden and complete air loss) can pose
an extreme hazard for both vehicle
occupants and other road users.< To maintain good handling and vehicle
response, use only tires of a single tread
configuration from a single manufac-
turer. BMW tests and approves wheel
and tire combinations, refer to page 116.
DOT Quality GradesTread wear
Traction AA A B C
Temperature A B C
All passenger vehicle tires must
conform to Federal Safety
Requirements in addition to these
grades. rating based on the wear rate of the tire
when tested under controlled condi-
tions on a specified government test
course.
For example, a tire graded 150 would
wear one and one-half (1g) times as
well on the government course as a tire
graded 100. The relative performance
of tires depends upon the actual condi-
tions of their use, however, and may
depart significantly from the norm due
to variations in driving habits, service
practices and differences in road char-
acteristics and climate.
