Driving
72 Active cruise control represents a technological
advance over the familiar cruise control and is a
welcome relief from the constant adjustment of
speed that can accompany driving in traffic on
freeways or other high-speed thoroughfares.
Especially on longer trips and in traffic conges-
tion, the system can reduce fatigue and tension,
while increasing your enjoyment of driving.
Please use it safely and responsibly.
In addition to holding a steady cruising speed, if
you encounter slower vehicles ahead, active
cruise control will, within limits, adjust your
vehicle's speed automatically so that you can
flow with the traffic without having to make con-
stant adjustments. If, for example, while cruis-
ing at the selected speed, you begin to
approach a slower vehicle ahead of you in the
same lane, the system will reduce your vehicle's
speed to the same as that of the vehicle ahead
to maintain your selected distance setting. You
can vary the following distance, which will vary
with speed. Based on your selected distance
setting, the system automatically decreases the
throttle setting and lightly applies the brakes if
necessary. In addition, if the vehicle ahead of
you slows to a complete stop, the system can
follow this action within the given scope and
can also accelerate from a complete stop if the
vehicle ahead of you drives off again shortly
thereafter. During braking, your vehicle brake
lamps will automatically illuminate to alert a fol-
lowing driver to take action. In addition, it may
be necessary for your vehicle to downshift the
automatic transmission to maintain the dis-
tance setting selected. As soon as the road in
front of you has no moving vehicles, the system
will accelerate to your desired speed. This set
speed is also maintained on downhill grades,
however the vehicle speed can drop below the
set speed when driving uphill if the engine out-
put is not sufficient.
Active cruise control cannot detect stop
signs, red lights, or any object that is
stopped or is blocking the road.
Active cruise control is not and must not be
used as a collision avoidance/warning system.
Since this active cruise control system is a new
technology and operates differently from con-ventional cruise control systems which you may
be accustomed to, it is necessary that you read
all of the pages relating to this system before
use. Carefully read and observe the information
on the system limitations beginning on page76
to obtain a good command of the system and its
range of applications.<
Brake pedal feel
When the system brakes and you also depress
the brake pedal, a somewhat different braking
feel results.
Professional* navigation system
If a navigation DVD is in the drive, refer to
page142, within limits the system adjusts the
accelerating and braking behavior of the vehicle
to the road you are driving on.
To ensure that the system is informed of
the current course of the road, always use
the latest navigation DVD if possible.<
When the vehicle position is unknown, e. g.
when you leave the map area, this influence of
the navigation system is not available.
Applications
Please try the system first during sparse traffic
and clear road conditions so that you can get
used to the system. After you have experience
and understand the system, only then use it
during normal traffic.
As with conventional cruise control systems,
active cruise control in no way reduces or sub-
stitutes for the driver's own personal experi-
ence, responsibility, alertness and awareness in
adjusting speed, braking or otherwise control-
ling the vehicle. The driver should decide when
to use the system on the basis of road, traffic,
visibility, and weather conditions. Active cruise
control is intended for use on highway-type
roadways where traffic is moving relatively
smoothly as well as in slow-moving traffic. Do
not use the system in city driving; in complex
driving situations; heavy traffic such as during
rush hour; on curvy, winding roads, slippery
roads or roads with sharp curves such as high-
way off-ramps; during inclement weather such

76 Do not apply adhesive labels etc. in the area of
the short-range sensors.If the sensor is not aligned properly, e. g. due to
damage, the active cruise control cannot be
activated.
System limitations
As with conventional cruise control sys-
tems, active cruise control in no way
diminishes or substitutes for the driver's own
personal responsibility, alertness and aware-
ness in adjusting speed, braking or otherwise
controlling the vehicle. The driver should
decide when to use the system on the basis of
road, traffic, visibility, and weather conditions.
Active cruise control is intended for use on
highway-type roadways where traffic is moving
relatively smoothly. Do not use this system in
city driving; in complex driving situations; on
curvy, winding roads, slippery roads or roads
with sharp curves such as highway off-ramps;
during inclement weather such as snow, strong
rain or fog; or when entering interchanges, ser-
vice/parking areas or toll booths. It is also
important to regulate your vehicle's speed and
distance setting within applicable legal limits.
Always be ready to take action or apply the
brakes if necessary, especially when the sys-
tem is actively following a vehicle in front of
you.<
Always remember that the range and abil-
ity of the system do have physical limita-
tions. For example, the system may not detect
vehicles driving ahead if they suddenly brake
heavily in stop-and-go traffic during accelera-
tion. The system will not apply the brakes or
slow your vehicle when a very slow-moving
vehicle, stopped vehicle or stationary object is
in the lane ahead of you, for example when
approaching a traffic light or parked vehicle or
when a vehicle is stalled in your lane. Also, the system does not react to oncoming traffic,
pedestrians or other types of potential traffic
s u c h a s a r i d e r o n a h o r s e b a c k . I t i s a l s o p o s s i b l e
that the system may not detect smaller moving
objects such as motorcycles or bicycles. Be
especially alert when encountering any of these
situations as the system will neither automati-
cally brake, nor provide a warning to you. Also,
be aware that every decrease in the distance
setting allows your vehicle to come closer to a
vehicle in front of you and requires a heightened
amount of alertness.<
The system cannot allow the vehicle to drive off
automatically in situations that make driving off
considerably more difficult, e.g. on steep uphill
grades, with a heavy trailer or before raised
areas in the road.
Near radio astronomy stations, the system
radar is deactivated at speeds under 20 mph/
30 km/h due to legal regulations.
Be certain to interrupt the system when
you pull into an exit lane for a highway
offramp.<
Also, vehicles traveling in a staggered manner
on a highway may cause a delay in the system's
reaction to a vehicle in front of you or may cause
the system to react to a vehicle that is actually in
the lane next to yours. Always be ready to take
action or apply the brakes if necessary.
In addition, the system is interrupted
whenever the driver applies the vehicle
brakes, shifts the transmission from drive/D to

Thinking ahead when driving
Avoid unnecessary acceleration and braking.
To do so, maintain the appropriate distance
from the vehicle in front of you. An anticipatory
and smooth driving style reduces fuel con-
sumption.
Avoiding high engine speeds
Use 1st gear only for starting off. Accelerate
rapidly in 2nd gear and above. Avoid high
engine speeds in doing so and shift into the
next gear early.
When you have reached the desired speed,
shift into the highest possible gear and drive
with the lowest possible engine speed while
maintaining a constant a vehicle speed.
In general: driving at a low engine speed
reduces fuel consumption and minimizes wear.
Taking advantage of coasting
When approaching a red light, let off the gas
and allow the vehicle to coast to a stop in the
highest possible gear.
On steep roadways, let off the gas and allow the
vehicle to roll in the appropriate gear.
The flow of fuel is interrupted when coasting.
Switching off the engine during longer
stops
Switch off the engine at longer stops such as
traffic signals, railroad crossings, or in traffic
jams. Even having the engine switched off for
approx. 4 seconds results in fuel savings.
Switching off functions currently not
required
Functions such as the cooling function of the
automatic climate control, seat heating or rear
window defroster draw large amounts of power
and consume additional fuel. Their influence is
particularly pronounced in city traffic and stop &
go operation. For this reason, it is a good idea to
switch these functions off when they are not
really needed.
Having maintenance carried out
Have the vehicle serviced regularly in order to
achieve the optimum economy and service life
of your vehicle. BMW recommends having the
maintenance performed by a BMW center. Also
please pay attention to the BMW maintenance
system, refer to page237.
General driving notes
Closing luggage compartment lid/
tailgate
Operate the vehicle only when the lug-
gage compartment lid/tailgate is com-
pletely closed. Otherwise, exhaust fumes could
enter the interior of the vehicle.<
If it is absolutely necessary to drive with the lug-
gage compartment lid open:
1.Close all windows and the glass sunroof or
panorama glass sunroof.
2.Increase the air volume of the automatic cli-
mate control to a high level, refer to
page116.
Hot exhaust system
As in all vehicles, extremely high temper-
atures are generated on the exhaust sys-
tem. Do not remove the heat shields installed
adjacent to it, and never apply undercoating to
them. When driving, standing at idle and while
parking take care to avoid possible contact
between the hot exhaust system and any highly
flammable materials such as hay, leaves, grass,
etc. Such contact could lead to a fire, and with it
the risk of serious property damage as well as
personal injury. Do not touch hot exhaust tail
pipes. Otherwise there is a risk of burns.<
Hydroplaning
When driving on wet or slushy roads,
reduce road speed. If you do not, a wedge
of water can form between tires and road sur-
face. This phenomenon is referred to as hydro-
planing, and is characterized by a partial or
complete loss of contact between the tires and
