You can store and automatically main-
tain any desired vehicle speed above
approx. 25 mph (40 km/h).
The stored speed is deleted when the
motor is switched off.
1 Accelerate Tap the lever briefly:
The system records and maintains the
current vehicle speed. Every time you
tap the button the speed increases by
approx. 0.6 mph (1 km/h).
Hold the lever in this position:
The vehicle accelerates without pres-
sure on the accelerator pedal. As soon
as you release the lever, the system
records and maintains the current
speed.
2 DecelerateHold the lever in this position:
With the cruise control active, the system
automatically reduces the throttle open-
ing to slow the vehicle. As soon as you
release the lever, the system records and
maintains the current speed.
Tap the lever briefly:
Each time you tap it you decelerate
approx. 0.6 mph (1 km/h) if you are
cruising at a controlled speed.3 ResumeTap the lever briefly:
The vehicle accelerates to and main-
tains the last speed stored.4 OffTap the lever briefly:
Immediately deactivates the cruise con-
trol.
In addition, the system is also automati-
cally disabled in response to the follow-
ing conditions:
dWhen you apply pressure to the
brake or clutch pedal, and when you
move the automatic transmission
selector lever from Drive to Neutral,
dif you exceed the programmed speed
by more than 10 mph (16 km/h) for a
period of more than 30 seconds.The system is switched off and the
stored speed deleted from its memory
when you turn the ignition key to posi-
tion 0.
a
Refrain from using the cruise con-
trol on twisting roads, when high traffic
density prevents driving at a constant
speed and when driving on slippery
(snow, rain, ice) or loose (stones, sand)
road surfaces.c
b
If, on a downhill gradient, the
engine braking effect is not sufficient,
the controlled speed can be exceed-ed.
Speed can drop on uphill grades if the
engine output is insufficient.c

Automatic Stability Control plus
Traction (ASC+T)This system is designed to enhance
operating stability, especially while
accelerating and during cornering.
ASC+T automatically assumes opera-
tion each time you start the engine.
The indicator lamp in the instrument
cluster goes out shortly after you switch
on the ignition.
To deactivate the systemPress the button; the indicator lamp
comes on.To reactivate the systemPress the button again; the indicator
lamp goes out.Indicator lamp flashesThe system is actively regulating drive
torque in response to monitored vehicle
operating conditions.Indicator lamp fails to go out after
the engine is started, or comes on
in the course of normal vehicle
operationThe system has a defect. The vehicle
normally remains operational even with-
out ASC+T. Consult your authorized
BMW Retailer for repair.When ASC+T is switched off, you drive
with a conventional drive system. We
recommend that you deactivate the
system for increased traction
dwhen rocking the vehicle or starting
off in deep snow or on loose surfaces
(refer to "Starting off", page 10 5)
dor when driving with snow chains.
b
But even with ASC+T the laws of
physics can not be suspended. Any
consequences arising from traction loss
due to excessive vehicle speed remain
the responsibility of the driver. We
therefore urge you to avoid using the
additional safety margin of the system
as an excuse for taking risks.c
For more details, please refer to section
"Advanced Technology" on page 156.

Temperature
This program is designed for
rapid removal of ice and con-
densation from the windshield and side
windows.
The air conditioner cools and
dehumidifies incoming air
before reheating it to the selected tem-
perature.
Depending on the weather, the wind-
shield may fog over briefly when the
engine is started.
Switching off the air conditioner at out-
side temperatures below approx. 41 5F
(56) will prevent the windows from
fogging up.
Frequently switching the air condi-
tioner on and off may also promote the
formation of condensation on the win-
dow surfaces.
b
Condensation forms in the air
conditioner system during operation,
which then exits under the vehicle. It is
not unusual for a small puddle to form
there.c
You can respond to unpleas-
ant odors in the outside air
by temporarily excluding the outside air.
The system then recirculates the air
currently within the vehicle.
A
The indicator lamp comes
on to confirm that the rear
defroster is operating.
The defroster switches off automatically
after approx. 15 minutes.
On both the driver's and the
passenger's side you can
adjust the specific temperature. The fig-
ures in the display provide a general
indication of interior temperature. We
recommend 70 5F (226) as a standard
setting for comfortable travel, both with
and without the air conditioner. When
you start the vehicle, the system
ensures that the selected temperature
is achieved as quickly as possible and
maintained at a constant level by the
control.

To ensure that your vehicle provides
maximum economy throughout a long
service life, we request that you
observe the following.
Engine and differentialUp to 1,250 miles (2,000 km):
Drive at different engine speeds and
vehicle speeds, but be careful not to
exceed the following engine speed:
4,500 rpm
Refrain from using full throttle and avoid
pressing the accelerator beyond the
kickdown point.
After 1,250 miles (2,000 km) you can
gradually increase the number of revo-
lutions or the speed.
You should also observe these break-in
procedures if the engine or differential
is replaced later in the course of the
vehicle service life.
TiresDue to technical factors associated with
their manufacture, tires do not achieve
their full traction potential until an initial
break-in period has elapsed. This
means that you should drive with addi-
tional caution for the first 200 miles
(300 km).Brake systemBrake pads and disks attain their opti-
mal wear patterns only after approx.
300 miles (500 km).
EngineDo not allow the engine to warm to its
normal operating temperature by leav-
ing it idling with the vehicle parked.
However, when starting in extremely
cold weather it is a good idea to allow
the engine to run at fast idle for about
30 seconds before getting underway;
this precaution ensures adequate lubri-
cation.
Avoid high engine speeds while the
engine is still cold; this helps avoid pre-
mature wear and reduced service life.
When driving under high engine loads
(acceleration, steep hills), try to keep
the engine running above 1,500 rpm.
We recommend downshifting into a
more suitable range, especially when
driving up extended inclines.
It is a good idea to follow extended
periods of low-speed operation (dense
urban traffic, stop-and-go driving) by
maintaining an engine speed consis-
tently above 3,000 rpm for several
miles. This procedure helps prevent
deposits from accumulating in the
engine.
