OdometerYou can activate the displays shown in
the illustration with the ignition key in
position 0 by pressing the button in the
instrument cluster (arrow).Trip odometerTo reset the trip odometer to zero,
press the button (arrow) with the igni-
tion key in position 1 or higher.
Variable pre-warning zoneThe yellow pre-warning zone displays
current permissible engine speed,
depending on the engine temperature.
As the engine temperature climbs,
some of the sectors for this pre-warning
zone will go out one after the other.
Avoid engine speeds in the pre-warning
zone if possible.
Absolutely avoid engine speeds in the
red warning zone.
To protect the engine, the fuel supply is
interrupted when you approach this
sector.
The general operating temperature is
between 175 7 (80 6) and 250 7
(120 6). During performance-oriented
driving, do not exceed the maximum
temperature of 300 7 (150 6).

ComputerAdjustments From ignition key position 1 the time of
day appears in the display.
To set ahead: turn the knob to the right.
To set back: turn the knob to the left.
The adjustment speed will increase the
longer you continue to hold the knob.
To change the display mode: press the
knob briefly. Every time you press the
knob, the clock display alternates
between the 12-hour or 24-hour mode.
In ignition key position 0: the time is
displayed for a few seconds after you
press the left knob (refer to "Odom-
eter", page 70).
Outside temperature You can change the units of measure
(6/7) for the outside temperature
display by pressing the right-hand reset
knob in the instrument cluster while the
temperature display is active.
Ice warning If the outside temperature drops to
about 37.5 7 (+3 6), then the
computer will automatically switch to
show the outside temperature. In addi-
tion, a signal sounds as a warning and
the display flashes for a brief period.
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.<

Flat Tire Monitor
M Engine dynamics control
In the event of a flat tire
The indicator lamp in the instru-
ment cluster will light up red in
the event of a flat tire with
ensuing loss in pressure. In addition, an
acoustic signal is sounded. To come to
an immediate stop, reduce speed, while
avoiding any sudden, jerky braking or
steering maneuvers.
Fix the flat tire using the M Mobility
system, refer to page 126.
Reset the indicator lamp: the red indi-
cator lamp has to be switched off
manually after putting on a new wheel.
At this point, hold the Flat Tire Monitor
button down until the indicator lamp
goes out. Reinitialize the system after-
ward.
The Flat Tire Monitor cannot alert
you to severe and sudden tire
damage caused by external factors.
Another factor which the Flat Tire
Monitor does not recognize is the
balanced and very gradual pressure
loss that takes place in all tires over an
extended period of time.<
Check the tire inflation pressure
on a regular basis and correct if
necessary, refer to page 24.
Under certain circumstances, there
may be false warnings or a delayed
detection of losses in pressure when
driving on snow-covered or slippery
road surfaces.
Performance-oriented driving (slip at
the drive wheels, high levels of lateral
acceleration) can also delay the
appearance of status reports in the Flat
Tire Monitor's display.<
System malfunctionAs long as there is still a malfunction,
the indicator lamp in the instrument
cluster will stay lit up yellow.
Please contact your BMW center for
additional information.
The system (sport-mode identification)
will cause the engine to respond spon-
taneously to the motion of the acceler-
ator pedal. Activating/deactivating
sport-mode identificationActivating: with the key in ignition key
position 2, press the sport button. The
indicator lamp will light up.
The vehicle may gain speed
without any additional pressure on
the accelerator pedal when the system
is activated.<
Deactivating: press the sport button
again; the indicator lamp will go out.
The sporty-comfortable mode is deacti-
vated every time the engine is started.

Repairing a flat tire Inflating tire to correct pressure1. Take the hose with the manometer
out and screw it onto the valve.
Take the plug out and plug it into the
cigarette lighter socket in the
passenger compartment
2. Reset the air pressure to 29 psi
(200 kilopascal), and:
>Increase tire pressure: turn on the
M Mobility system (Position I). Turn
the unit off while you check the
current setting for the tire pressure
>Decrease tire pressure: turn the
screw on the back of the mano-
meter, a valve located there will
open
Even if the tire fails to hold the
pressure, you should still carry out
Step 3 before proceeding to drive the
vehicle again, refer to "Distributing
sealant" for more information. Then
repeat Steps 1 through 3.
The use of the M Mobility system may
be ineffective if the damaged area in
the tire is larger than approx. 0.16 in
(4 mm). Please consult the nearest
BMW center if the tire cannot be
temporarily repaired with the M Mobility
system.<
3. Unscrew the hose from the valve
and stow the M Mobility system in
the luggage compartment. Screw
the dust cap onto the valve again.
Do not exceed the maximum
speed limit described below,
otherwise it could lead to accidents.<
After the flat tire has been fixed and you
start driving again, do not exceed a
maximum speed of 45 mph (80 km/h).
You will find corresponding
instructions for using the
M Mobility system on the device.
Replace the defective tire as soon as
possible and have the new wheel
balanced. Reinitialize the Flat Tire
Monitor, and refer to page 78 for further
information. Have the M Mobility
system refilled. Contact your BMW
center for this.<
Protect valve stems against dirt using
screw-on dust caps. Dirty valve stems
frequently lead to slow pressure loss.
