Onboard computer
*
Mode selectionFrom ignition key position 1 and up, you
can call up information from the on-
board computer shown in the display of
the instrument cluster using the button
in the turn signal lever. By pressing the
button briefly in the direction of the
steering column, you can call up a new
function for display.
The displays appear in the following
order:
Time, outside temperature, average fuel
consumption, cruising range, average
vehicle speed.
Starting with ignition key position 1, the
last active setting is displayed.46cde096
Outside temperature You can change the units of measure-
ment (6/7) for the outside tempera-
ture display by pressing the right-hand
reset button in the instrument cluster
when the temperature display is active. 46cus008
Ice warning If the outside temperature drops to
approx. 37.5 7 (+3 6), the onboard
computer automatically switches to the
outside temperature display. In addi-
tion, a signal sounds as a warning and
the display flashes for a brief period.
The warning is repeated whenever the
temperature climbs to at least 43 7
(+6 6) following the last warning and
then drops back to 37.5 7 (+3 6).
The ice warning does not alter the
fact that surface ice can form at
temperatures above +37.5 7 (+3 6),
on bridges or shaded road surfaces, for
instance.<

Tire Pressure Control (RDC)
*
The conceptRDC monitors the tire pressure at all
four wheels – even while you are driv-
ing. The system provides an alert when-
ever the inflation pressure drops signifi-
cantly below the specified pressure in
one or more tires.
In order for the system to "learn" cor-
rect tire inflation pressure, check the
pressure in all the tires, compare your
pressures with those in the tire inflation
tables (page 28), and make corrections
as necessary. Then activate the system.
This indicator lamp in the
instrument cluster informs you
whenever the tire pressure is
not normal.
Activate the system 1 Turn the ignition key to position 2
(do not start the engine)
2 Press the button long enough for
the indicator lamp in the instrument
cluster to light up yellow for a few
seconds
3 After you have driven a few minutes,
RDC imports the current tire inflation
pressures as the nominal values to be
monitored.
You will only have to repeat this proce-
dure following a correction of the tire
inflation pressure. Otherwise, the RDC
functions automatically when the igni-
tion key is in position 2, and thus oper-
ates whenever the vehicle is driven.46cus013
Loss of tire pressureIf the inflation pressure has dropped
significantly over a long period of time
(which is normal for any tire), the
indicator lamp will come on with a
yellow lamp.
This alerts you that you should have the
tires inflated to the specified pressures
as soon as possible.
If you are prompted to check the
tire pressure shortly after a cor-
rection has been made, this indicates
that the corrected values were not ac-
curate. Please check the inflation pres-
sure again and make corrections ac-
cording to the inflation pressure table.
Then activate the system once again.<

Antilock Brake System (ABS)Antilock Brake System (ABS)/
Cornering Brake Control (CBC) CBC is an advanced engineering de-
sign of the ABS. When braking while
cornering at high speed or braking dur-
ing high lateral acceleration, or when
braking during a lane change, vehicle
stability is improved and steering re-
sponse is enhanced.
In the event of a malfunction
If the ABS warning lamp in the
instrument cluster lights up,
refer to page 22. The brake
system then reverts to conventional
operation as on vehicles without ABS.
However, have the brake system
checked by your BMW center as soon
as possible, to prevent undetected
defects and cumulative faults from
adversely affecting the brake system.
ABS warning lamp for Canadian
models.
If the brake warning lamp
comes on together with the indi-
cator lamps for ABS and DSC –
refer to page 21 – the entire
ABS, CBC and DSC control sys-
tem has failed. Continue driving
cautiously and defensively.
Avoid full brake applications.
This could cause the vehicle to lose
stability and you might no longer be
able to control it.
Have the system checked as soon as
possible by your BMW center.

Coolant Brake fluidAdding coolant Wait until the engine cools before re-
moving the cap from the expansion
tank. The coolant gauge needle in the
instrument cluster must be located in
the blue zone. If it is not, there is a
danger of scalding.
1 Turn the cap slightly counterclock-
wise in order to allow accumulated
pressure to escape. Then open
the cap
2 If the coolant is low, slowly add
coolant until the correct level is
reached – do not overfill.
The coolant is a mixture of water and
extended-duty antifreeze with corrosion
inhibitor. Always maintain the pre-
scribed all-season 50:50 mixture ratio
for year-round protection against inter-
nal corrosion. No other additives are
required.
Replace the coolant every four years.If the warning lamp for the brake sys-
tem comes on and the parking brake
has been released:
Check the brake fluid level. Fill it to the
top mark ("MAX") if necessary.
For adding brake fluid or for determin-
ing and correcting the cause of brake
fluid loss, consult your BMW center.
Your BMW center is familiar with the
specifications for factory-approved
brake fluids (DOT 4).
Brake fluid loss can result in extended
pedal travel. Comply with the informa-
tion provided on page 117.
460de128
Brake fluid is hygroscopic, that is,
it absorbs moisture from the air
over time.
In order to ensure the safety and reli-
ability of the brake system, have the
brake fluid changed every two years by
a BMW center. Refer also to the Service
and Warranty Information Booklet (US
models) or the Warranty and Service
Guide Booklet (Canadian models).
Brake fluid is toxic and damages the
vehicle's paint. You should always store
it in its original container and in a loca-
tion 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 envi-
ronmental laws regulating the dis-
posal of brake fluid.<
