Coolant temperature gauge Service Interval DisplayBlueThe engine is still cold. Drive at
moderate engine and vehicle speeds.RedWhen you switch on the ignition, the
warning lamp comes on briefly to
confirm that the system is operational.
Comes on while driving: the engine is
overheated. Switch off the engine
immediately and allow it to cool down.367de007
Between the blue and red zonesNormal operating range. It is not
unusual for the needle to rise as far as
the edge of the red zone in response to
high outside temperatures or severe
operating conditions.
Checking coolant level, refer to
page 125.
Green lamps The number of illuminated lamps
decreases as the time for your next
maintenance visit approaches.Yellow lamp This field appears together with
OILSERVICE or INSPECTION.
This alerts you that maintenance is due.
Please arrange for an appointment with
your BMW center.Red lamp Maintenance is overdue.367us709

To enter the timeEnter the numbers for hours and
minutes by pressing the button.
Enter the hour first. Each time the
button is pressed, the hour display
increases by one. Pressing and holding
the button starts the rapid advance.
Confirm the time set with the
button. Now enter the minutes when
two zeros appear.
Enter the minutes in the same manner
as the hours.
Press the save button : the time is
started exactly on the second. The
colon stops flashing.To reset the timePress and hold the button for
approx. 3 seconds: enter the hour when
the colon begins to flash.
Enter the numbers by pressing the
button in the same manner as when
entering the time.
Setting the 12-hour or 24-hour
modePress and hold the buttons
simultaneously for approx. 1 second.
Then press the button. Now, the
mode changes from 12 to 24 hours
whenever you press the button.
When you select the 12-hour mode,
AM or PM will appear on the right-hand
side of the display panel.
The last mode selected is adopted
when you press or automatically
stored approx. 5 seconds after the last
setting.
Outside temperatureIf the outside temperature drops to
approx. +37.5 7 (+3 6), a warning
signal sounds (ice warning). The
temperature display appears automati-
cally and flashes for 8 seconds.
The warning is repeated whenever the
temperature has reached at least
+43 7 (+6 6) and then drops to
+37.5 7 (+3 6) again.
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.< 367us712

The conceptThis system helps provide additional
dynamic stability, particularly when
starting off, accelerating and cornering.
ASC+T recognizes the danger present
in traction loss and will increase driving
stability and traction by reducing the
engine's output, and if necessary, by
applying the brakes individually to the
rear wheels.
ASC+T is available as soon as the
engine starts up.
Indicator lamp
The indicator lamp in the instru-
ment cluster goes out shortly
after you switch on the ignition,
refer to page 22.
The indicator lamp flashes:
ASC+T controls the drive and braking
forces.
If the indicator lamp fails to go out after
the engine is started, or if it comes on
during normal driving and stays on:
There is a system malfunction or the
system was switched off with the
button. Consequently, interventions to
increase driving stability (as described
in the preceding column) are not avail-
able. You can still drive the vehicle
normally without ASC+T.
In the event of a malfunction, please
consult your BMW center.
Switch off ASC+TPress the button (arrow); the indicator
lamp comes on and stays on.
In the following rare situations, it may
be effective to switch off the ASC+T for
a brief period:
>When rocking the vehicle or starting
off in deep snow or on loose surfaces
>When driving with snow chains.
To maintain vehicle stability, drive
with the ASC+T switched on
whenever possible.<367de701

Dynamic Stability Control (DSC)*Switch off DSC/activate ADBPress the DSC switch (arrow) Ð the indi-
cator lamp comes on and remains on.
DSC has been switched off; ADB is in
ready mode.
In the following exceptional circum-
stances, it may be effective to activate
the ADB for a short period:
>When rocking the vehicle or starting
off in deep snow or on loose surfaces
>When driving on snow-covered
grades, in deep snow, or on a snow-
covered surface that has been
packed down from being driven on
>When driving with snow chains.367de739
Switch off DSC and ADBHold the DSC switch down for at least
3 seconds. The indicator lamp and the
red warning lamp for the brake
hydraulic system remain on.
In this case, no interventions to
increase stability and traction for engine
and brakes are carried out.
To maintain vehicle stability, drive
with the DSC switched on when-
ever possible.<
Reactivate DSC and ADBPress the button again; the indicator
lamp or the indicator lamps will go out.
The laws of physics cannot be
repealed, even with DSC. It will
always be the driver's responsibility to
drive in a manner that matches road
conditions. We therefore urge you to
avoid using the additional safety margin
of the system as an excuse for taking
risks.
The DSC is deactivated and will not
carry out any stabilizing intervention
when the ADB is in ready mode.
Do not make any modifications to the
DSC system. Allow only authorized
technicians to perform service proce-
dures on the DSC.<
You will find additional details
concerning DSC in the chapter
"Advanced technology" on page 165.
