Starting the engine
Do not run the engine in closed rooms,
otherwise the inhalation of toxic exhaust
gases can cause unconsciousness and death.
The exhaust gases contain carbon monoxide,
an odorless and colorless, but highly toxic gas.
Never leave an unattended vehicle with the
engine running, otherwise such a vehicle repre-
sents a potential safety hazard.
Before leaving the car with the engine running,
place the transmission in idle or move the
selector lever to position P and forcefully apply
the parking brake to prevent the car from mov-
ing.<
Avoid frequent starting in quick succes-
sion as well as repeated start attempts in
which the engine does not start. Otherwise, the
fuel is not burned or incompletely burned and
there is a danger of overheating and damaging
the catalytic converter.<
Do not wait for the engine to warm up while the
vehicle remains stationary. Start driving right
away, but at moderate engine speeds.

Cruise control*
The concept
Cruise control is available for use at speeds of
approx. 20 mph or 30 km/h. The car then stores
and maintains the speed that you specify using
the lever on the steering column. In order to
maintain the specified speed, the system
brakes the vehicle when the engine braking
effect is insufficient on downhill gradients.
Do not use cruise control when driving at
constant speed is prevented by adverse
conditions, e.g. winding roads, dense traffic or
poor road conditions due to, e.g., snow, rain, ice
or loose surfaces. Otherwise you could lose
control of the vehicle and cause an accident as a
result.<
Manual transmission
You can shift gears while cruise control is acti-
vated. An indicator lamp notifies you that you
should shift gears when you drive for an
extended period at very high or very low engine
speeds, or the system is deactivated.

Maintaining current speed
Tap the lever, arrow 1, or pull it briefly, arrow 2.
The car's current speed is stored and main-tained. It is displayed on the speedometer and
briefly in the instrument cluster.
On uphill gradients, it may prove impossible to
maintain the set speed if current engine power
output is insufficient. If the engine braking
effect is insufficient on downhill slopes, the sys-
tem will brake the vehicle slightly.
Increasing desired speed
Repeatedly press the lever to the resistance
point or beyond, arrow1, until the desired
speed is reached.
>Each time the lever is pressed to the resis-
tance point, the desired speed is increased
by approx. 1 mph or 1 km/h.
>Each time the lever is pressed beyond the
resistance point, the desired speed is
increased by up to 5 mph or 10 km/h.
The system stores and maintains the speed.
Accelerating using the lever
Accelerating slightly:
Press the lever to the resistance point, arrow 1,
until the desired speed is reached.
Accelerating significantly:
Press the lever beyond the resistance point,
arrow 1, until the desired speed is reached.
The vehicle accelerates without pressure on
the accelerator pedal. The system stores and
maintains the speed.
Decreasing speed
Repeatedly pull the lever to the resistance point
or beyond, arrow 2, until the desired speed is
displayed.
>Each time the lever is pulled to the resis-
tance point, the desired speed is decreased
by approx. 1 mph or 1 km/h.
>Each time the lever is pulled beyond the
resistance point, the desired speed is
reduced by up to 5 mph or 10 km/h until the
minimum speed of 20 mph or 30 km/h is
achieved.
The system stores and maintains the speed.

Active cruise control*
The concept
With active cruise control, you can select a
desired speed which is not only automatically
maintained when driving on open roadways, but
also varied to maintain a selected distance set-
ting as slower traffic is encountered.
Active cruise control is 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 high-
ways or other high-speed thoroughfares. Espe-
cially on longer trips, the system can reduce
fatigue and tension, while increasing your
enjoyment of driving. Please use it safely and
responsibly.
Within the limits of its capability, the system
automatically adapts the car's speed to that of a
slower vehicle in front of you. You can specify

Driving
68 the distance to be maintained from the vehicle
in front in four stages. For safety reasons, the
distance is speed-dependent. Based on your
selected distance setting, the system automat-
ically decreases the throttle setting and lightly
applies the brakes if necessary. The vehicle
brake lamps will automatically illuminate to sig-
nal a following driver to take action. In addition,
it may be necessary for the vehicle or the driver
to downshift, depending on the kind of trans-
mission your vehicle is equipped with, to main-
tain the distance setting selected. If the vehicle
ahead speeds up or when the lane ahead
becomes clear, your vehicle will accelerate to
the speed you have selected by increasing the
throttle setting and shifting gears automatically
or by the driver as needed. Your selected speed
will be held when driving downhill, too.
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, you are strongly urged to
read all of the pages relating to this system
before use. Pay special attention to the System
limitations section beginning on page71.
Braking sensation
>If you step on the brake pedal while the sys-
tem is braking, pedal sensation will be
slightly different from the usual.
>Possible noises during automatic braking
are normal.
Manual transmission
You can shift gears while cruise control is acti-
vated. An indicator lamp notifies you that you
should shift gears when you drive for an
extended period at very high or very low engine
speeds, or the system is deactivated.
Range of applications
The minimum desired speed is 20 mph or
30 km/h, the maximum desired speed is
110mph or 180km/h.
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; heavy traffic such as during rush
hour; 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 inter-
changes, service/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 system is actively following a vehicle in front
of you. Otherwise driving situations could result
that pose the risk of accidents.<

speed without the driver needing to intervene.
HDC can be activated as long as you are driving
under approx. 20 mph or 35 km/h. When driving
downhill at a speed of under approx. 20 mph or
35 km/h, the vehicle's speed is automatically
reduced to slightly more than double walking
speed and maintained.
Increasing or decreasing speed
By accelerating or braking you can change this
speed within a range from approx. 3 to 15 mph,
approx. 5 to 25 km/h.
You can specify a target speed within the same
range using the cruise control
* lever on the

assistant will no longer hold the car in place

Things to remember when driving
126 The risk of hydroplaning increases with declin-
ing tread depth on the tires, refer also to Mini-
mum tread depth on page221.
Driving through water
Drive through water on the road only if it is
not deeper than 1 ft/30 cm, and then only
at walking speed at the most. Otherwise, the
vehicle's engine, the electrical systems and the
transmission may be damaged.<
Use the parking brake on inclines
On inclines, do not hold the vehicle for a
lengthy period using the clutch; use the
parking brake instead. Otherwise greater clutch
wear will result.<
For more information about the drive-off assis-
tant, refer to page91.
Braking safely
Your BMW is equipped with ABS as a standard
feature. Applying the brakes fully is the most
effective way of braking in situations in which
this is necessary. Since the vehicle maintains
steering responsiveness, you can still avoid
possible obstacles with a minimum of steering
effort.
Pulsation of the brake pedal, combined with
sounds from the hydraulic circuits, indicate that
ABS is in its active mode.
Driving in wet conditions
When roads are wet or there is heavy rain,
briefly exert gentle pressure on the brake pedal
every few miles. Monitor traffic conditions to
ensure that this maneuver does not endanger
other road users. The heat generated in this
process helps dry the pads and rotors to ensure
that full braking efficiency will then be available
when you need it.
Hills
To prevent overheating and the resulting
reduced efficiency of the brake system,
drive long or steep downhill gradients in the
gear in which the least braking is required. Even
light but consistent brake pressure can lead to high temperatures, brake wear and possibly
even brake failure.<
You can increase the engine's braking effect by
shifting down, all the way to first gear if neces-
sary. This strategy helps you avoid placing
excessive loads on the brake system. Down-
shifting in manual mode of the automatic trans-
mission, refer to page62.
Never drive with the clutch held down,
with the transmission in idle or with the
engine switched off; otherwise, engine braking
action will not be present or there will be no
power assistance to the brakes or steering.
Never allow floor mats, carpets or any other
objects to protrude into the area around the
pedals, otherwise pedal function could be
impaired.<
Corrosion on brake rotors
When the vehicle is driven only occasionally,
during extended periods when the vehicle is not
used at all, and in operating conditions where
brake applications are less frequent, there is an
increased tendency for corrosion to form on
rotors, while contaminants accumulate on the
brake pads. This occurs because the minimum
pressure which must be exerted by the pads
during brake applications to clean the rotors is
not reached.
Should corrosion form on the brake rotors, the
brakes will tend to respond with a pulsating
effect that even extended application will fail to
cure.
When the vehicle is parked
Condensation forms while the automatic cli-
mate control is in operation, and then exits
under the vehicle. Traces of condensed water
under the vehicle are therefore normal.

your BMW, refer to the Caring for your vehicle
brochure.
