Cruise control In addition, cruise control is canceled
automatically:
>if the brakes are applied
>if the clutch is depressed or the auto-
matic transmission selector lever is
moved from "Drive" to "Neutral"
>if the cruise speed is either exceeded
or not met for an extended length of
time, e. g., when you step on the
accelerator pedal.
To resume the stored settingPress button 4:
The vehicle accelerates to and main-
tains the last speed stored. When you
turn the ignition key to position 0, the
stored speed is deleted from the sys-
tem's memory and the system is deacti-
vated.To deactivate the system When the cruise control has been can-
celed, press button 1 again. The indica-
tor lamp goes out and the stored speed
is deleted.Do not use cruise control on twist-
ing roads, when high traffic density
prevents driving at a constant speed,
when the road surface is slick (snow,
rain, ice), or when the road surface is
loose (rocks, sand).<

To ensure that your vehicle provides
maximum economy throughout a long
service life, we request that you ob-
serve the following:
Engine and differentialUp to 1,200 miles (2,000 km):
Drive at varying engine speeds and
road speeds, but do not exceed the fol-
lowing engine or road speeds at this
time: 4,500/min or 100 mph (160 km/h).
Refrain from using full throttle and avoid
pressing the accelerator beyond the
kickdown point.
After 1,200 miles (2,000 km), you can
gradually increase the engine speed or
road 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. For this
reason, drive cautiously during the first
200 miles (300 km).Brake systemBrake pads and disks do not attain their
optimal wear patterns until after approx.
300 miles (500 km).
To break-in the separate parking brake
drums, apply the parking brake lightly
when coasting to a standstill (at a traffic
signal, for instance), provided that traf-
fic conditions allow you to do so.
To avoid corrosion, repeat this proce-
dure from time to time.
The brake lamps do not come on
when the parking brake is set.
Vacuum for the brake system servo unit
on your BMW is available only when the
engine is running. When you move the
car with the engine off – when towing,
for example – substantially higher levels
of pedal force will be required to brake
the vehicle.<
Brakes:
Do not drive with your foot resting
on the brake pedal. Even light but con-
sistent pedal pressure can lead to high
temperatures, brake wear, and possibly
to brake failure.
Aquaplaning:
A wedge of water can form between the
tires and the road surface when you op-
erate the vehicle on wet or slushy roads.
This phenomenon is referred to as
aquaplaning or hydroplaning. It is char-
acterized by a partial or complete loss
of contact between the tires and the
road surface. The ultimate results are
loss of steering and braking control.
Driving through water:
Do not drive through water more than
1 ft (30 cm) deep. Drive only at walking
speed, otherwise damage to the engine,
the electrical system and the transmis-
sion can occur.
Rear parcel tray:
Never use the rear parcel tray to store
heavy or bulky objects. They could pose
a danger to the occupants when the car
is braked heavily.
Break-in procedures Driving notes

108n
Disc brakesDisc brakes furnish optimum decelera-
tion and braking control and greater
fade resistance under heavy use.
When the vehicle is driven only occa-
sionally, during extended periods when
the vehicle is not used at all, and in op-
erating conditions where brakes appli-
cations are less frequent, there is an in-
creased tendency for corrosion of the
rotors and accumulation of contamina-
tion on the brake pads. This occurs be-
cause the minimal pressure that must
be exerted by the pads to clean the
rotors by brake applications is not
reached.
If the brake rotors are corroded, they
will tend to respond to braking with a
pulsating effect that even extended
brake applications will fail to cure.
For your own safety: Only use
brake linings that BMW has re-
leased for your particular vehicle model.
BMW cannot vouch for driving safety or
the suitability of brake linings other than
those they have released.<
Driving notesWhile driving in wet conditions and in
heavy rain, it is effective to apply light
pressure to the brake pedal every few
miles (kilometers). Watch traffic condi-
tions to ensure that this maneuver does
not endanger other road users. The
heat that is generated by the brake ap-
plications helps to dry the brake pads
and rotors.
Maximum braking force is obtained
while the wheels continue to rotate,
peaking when the wheels remain on the
verge of locking without actually doing
so. ABS maintains this state automati-
cally. If the ABS fails, you should revert
to the staggered braking technique
described on page 110.
Long or steep mountain descents do
not necessarily lead to reduced braking
efficiency if you drive downhill with the
transmission in a gear that allows mini-
mal brake applications (or, with an auto-
matic transmission, in an appropriate
lower range).
You can further increase the engine's
braking effect by selecting a lower gear,
downshifting as far as first gear or plac-
ing the selector lever in position (1).Should engine braking prove inade-
quate, you should still avoid extended,
continuous braking. Instead of main-
taining low to moderate pressure over
an extended period of time, you should
decelerate the vehicle by applying more
substantial force on the pedal (watch
for following traffic!) and then pausing
before repeating the application. This
staggered braking technique allows the
brakes to cool in the intervals between
active braking phases, preventing over-
heating and ensuring that full braking
capacity remains available at all times.
Do not coast with the clutch de-
pressed or with the transmission
or selector lever in neutral. Do not drive
with the engine shut off. The engine
provides no braking effect when the
clutch pedal is depressed or the trans-
mission is in neutral, and there is no
power-assist for brakes and steering
when the engine is not running.
Never allow floor mats, carpets or any
other objects to protrude into the area
around the accelerator, clutch and
brake pedals and obstruct their move-
ment.<

110n
Winter operationThe onset of winter is often accompa-
nied by rapid changes in weather. Adap-
tations in driving style should be accom-
panied by preparations on the vehicle
itself to ensure that your progress
through the winter remains safe and
trouble-free.CoolantBe sure that the coolant mixture is kept
at the year-round ratio of 50:50 of water
and antifreeze/corrosion protection.
This mixture provides protection against
freezing down to approx. – 347
(– 376). Replace the coolant every four
years.LocksBMW door lock deicer can be used to
free them if frozen. This deicer also
contains lubricant.
After using deicer, treatment with BMW
lock barrel grease is recommended.Rubber seals and components To prevent the weather-stripping from
freezing, apply a spray-on rubber treat-
ment or silicone spray to the door, hood
and luggage compartment lid seals.
A full range of car-care products is
available from your BMW center.<
Snow chains BMW snow chains
* can be mounted on
both summer and winter tires. Mount
them in pairs on the rear wheels only
and comply with the manufacturer's
safety precautions. Do not exceed a
maximum speed of 30 mph (50 km/h).
In this situation (snow chains mounted),
deactivate the DSC. Refer to page 81.
Starting offWe recommend that you use the man-
ual control switch to deactivate DSC
when starting off in deep snow or when
rocking the car to free it (refer to
page 81).Driving on low-traction road
surfacesUse smooth, gentle pressure to control
the accelerator pedal. Avoid excessive
engine speeds and shift to the next
higher gear at an early point. Adapt
your speed and driving style when ap-
proaching grades or slopes. Maintain
an adequate distance between yourself
and the car ahead.
BrakesWinter road conditions substantially
reduce the traction available between
the tires and the road surface.
Remember that braking distances will
be significantly longer as a result.
ABS is intended to prevent the wheels
from locking during brake applications,
thus helping to maintain vehicle stability
and steering response.
If the ABS does not respond in a critical
braking situation and the wheels lock:
Reduce the pressure on the brake
pedal until the wheels just start to roll
again while still maintaining enough
force to continue braking. Then in-
crease the pressure, reduce the pres-
sure when the wheels lock, reapply
pressure etc.
This staggered braking procedure will
reduce stopping distances while help-
ing you maintain steering control.
You can then attempt to steer around
hazards after you have reduced pres-
sure on the brake pedal.

130n
Washing your car Right from the start, you can wash your
new BMW in an automatic car wash.
Car wash systems that do not employ
brushes are preferable.
Wipe away tough dirt and loosen and
remove dead insects before washing
the car.
To prevent spots, avoid washing when
the hood is still warm, or immediately
after and during exposure to strong
sunlight.
When using an automatic car wash, be
sure that:
>The car wash system is suited for the
dimensions of your vehicle
>No damage will occur on vehicles
with attached body accessories (such
as spoilers or antennas). Consult the
car wash operator if necessary
>The wheels and tires of your vehicle
cannot be damaged by the convey-
ance devices of the car wash system
>The vehicle is cleaned with minimum
brush pressure, and that ample water
is available for washing and rinsing.Vehicles with rain sensor:
Clean the windshield regularly. Wax
from car washes or the presence of
dead insects can cause rain sensor
malfunctions.
Switch the rain sensor off when
the vehicle passes through the car
wash (refer to page 70). Damage could
occur by an undesired actuation of the
wipers if the system is not deacti-
vated.<
Parts of the car that are inaccessible
to the automatic washer – such as door
sills, door and hood edges, etc. –
should be cleaned by hand.
In the winter months, it is especially im-
portant to ensure that the car is washed
on a regular basis. Large quantities of
dirt and road salt are difficult to remove,
and they also cause damage to the ve-
hicle.
If spray wands or high-pressure
washers are used, be sure to
maintain an adequate distance between
the spray source and the vehicle's sur-
face. Inadequate distance and exces-
sive pressure can damage or weaken
the finish, making it more susceptible to
subsequent attack. In addition, mois-
ture could penetrate to vehicle compo-
nents, leading to long-term damage.<
When cleaning the headlamps,
please observe the following:
>Do not rub dry. Never use abrasives
or strong cleaning agents to clean the
covers
>Remove dirt and contamination
(such as insects) by soaking with
BMW Car Shampoo and then rinsing
with plenty of water
>Always use a deicer spray to remove
accumulated ice and snow – never
use a scraper.<
After washing the car, apply the
brakes briefly to dry them. Braking
efficiency might otherwise be reduced
by the moisture and the brake rotors
could also be corroded.<
Caring for your car

On vehicles with automatic transmis-
sion, the ATC (Adaptive Transmission
Control) uses a number of factors to
calculate the maximally efficient gear. In
this process, it considers your individ-
ual driving style as well as current driv-
ing conditions.
ATC recognizes your personal driving
style from the positions and movements
of the accelerator pedal, deceleration
when braking and lateral acceleration
through curves. Based on different shift
characteristics – from comfort-oriented
to performance-oriented – ATC will se-
lect the appropriate gear.
462uso11
In order to include driving conditions in
its calculations, ATC registers curves
and both uphill and downhill gradients.
For example, if you maintain speed
through a curve, it does not upshift. On
uphill gradients, it shifts up only when
the engine speed increases in order to
make more efficient use of power re-
serves. On downhill gradients, ATC
shifts down when the speed of the vehi-
cle increases and the driver must apply
the brakes.

Deceleration sensors continuously
monitor the physical forces acting upon
the vehicle. If, as the result of a frontal
collision, a deceleration is reached at
which the protection of the safety belts
alone is no longer adequate, the gas
generators of the driver and passenger-
front airbags are ignited. However, the
passenger-side airbag is only triggered
if an additional sensor has recognized
that the passenger seat is occupied.
In the event of a side collision, the Head
Protection and side airbags in the front
or rear
* are triggered if necessary.
390de319
The airbags located under the marked
covers inflate and unfold in a matter of a
few milliseconds. In this process they
tear through the rated breaking points
of the upholstered covers or press them
out.
Because the inflation process must be
virtually instantaneous, it is necessarily
accompanied by a certain amount of
ignition and inflation noise. The gas
required to inflate the airbags is not
dangerous, and the associated smoke
then dissipates.
The entire process is completed within
fractions of a second.Highly sensitive sensors monitor the
number of revolutions of the wheels,
steering angle, lateral acceleration,
brake pressure and the movement of
the vehicle around its vertical axis.
If differences in the wheel speeds oc-
cur, the system counteracts the danger
of wheelspin by reducing engine torque.
If necessary, the system also responds
with additional application of the brakes
at the rear wheels.
If the system detects an instability in the
vehicle's condition, the braking action
can also be directed to the front wheels
by the DSC in order to help stabilize the
vehicle.
You may need some time to become
accustomed to this system's interven-
tion. However, it provides optimum pro-
pulsive force and driving stability.
The braking intervention may be ac-
companied by a certain degree of
noise.
