been locked separately, you can open it
with this button in the footwell on the
driver's side when the vehicle is
stationary.
To closeThe handle recesses in the interior trim
panel of the luggage compartment lid
(arrows) make it easier to pull the lid
down.
To avoid injuries, be sure that the
travel path of the luggage
compartment lid is clear when it is
closed, as with all closing procedures.<
Operate the vehicle only when the
luggage compartment lid is
completely closed. Otherwise, exhaust
fumes could penetrate the interior of
the vehicle. Should it be absolutely
necessary to operate the vehicle with
the luggage compartment lid open:

AirbagsSitting correctly with airbags
Comply with the following instruc-
tions for the airbags. If you do not,
the airbags may not be able to provide
their maximum protection, with
resulting risks to personal safety. The
following information pertains to all
occupants:
Even though there is an airbag, wear a
safety belt every time you get in the
vehicle, because airbags supplement
the safety belts as an additional
restraint device.
Assume a sitting posture that is
comfortable and allows the greatest
possible distance between you and the
airbags.
Always hold the steering wheel by the
rim to keep any chance of injury to
hands or arms to an absolute minimum,
should the airbag deploy. Keep the
instructions regarding sitting properly in
your seat on page 45 in mind as well.
No one and nothing is to come between
the airbag and the seat occupant.
Do not use the cover panel above the
front passenger-side airbag as a
storage area.
Do not apply adhesive materials to the
cover panels of the airbags, cover them
or modify them in any other way.
Do not use any child restraint systems
on the passenger side. Children under
12 years of age, who are smaller than
5 feet (150 cm), may ride in the back
only.
If your vehicle is equipped with side
airbags in the rear passenger area, be
sure that child restraints are mounted
correctly and provided with the
greatest-possible distance between the
airbags in the side trim panels. Do not
allow children to lean out of the child's
seat in the direction of the side trim
panels. If they do so, serious injuries
can occur if the airbag is triggered. upright and be properly restrained
(infants and small children in appro-
priate child restraint systems; larger
children and adults using the safety
belts). Never let an occupant's head
rest near or on a side airbag because
the inflating airbag could cause a
serious or fatal injury. Please note that
the word "Airbag" imprinted on the door
trim panel indicates the airbag's loca-
tion.
Accident research shows that the
safest place for children in an automo-
bile is in the rear seat. However, a child
sitting in the rear seat and not properly
restrained may place his or her head on
or near the airbag, if so equipped. For
example, a child Ñ even though belted
Ñ may fall asleep with his or her head
against the side airbag. It may be diffi-
cult for a driver to ensure that children
in the rear seat will remain properly
positioned at all times and not place
their heads on or near the side airbag.
Therefore, we recommend that the rear
seat side airbags, if so equipped, be
deactivated if children will travel in the
rear seat.
The rear seat side airbags may already
have been deactivated, either at the
time of manufacture or by a BMW

Antilock Brake System (ABS)The concept ABS keeps the wheels from locking
while braking, thereby enhancing active
driving safety. The reason: locked
wheels are dangerous. When the front
wheels slide, the driver loses steering
control over the vehicle. Traction loss at
the rear wheels can cause the rear end
to break into an uncontrolled skid.
Based on current road conditions, ABS
can brake the vehicle within the
shortest possible distance and with the
greatest possible driving stability (on
straight-aways and curves, asphalt, ice,
wet road surfaces, etc.).
ABS is designed to meet two essential
requirements during every brake appli-
cation:
>To help provide vehicle stability
>To help maintain steering control and
maneuverability Ð on all types of road
surfaces (asphalt, concrete, mud,
wet, snow, ice). Braking with ABSThe system becomes operative once
the vehicle exceeds a speed of approx.
6 mph (10 km/h). Whenever the
vehicle's speed drops below approx.
4 mph (6 km/h), the ABS is deactivated.
This means that the wheels can lock in the final phase of a panic stop Ð a factor
of no significance in actual use.
The ABS system works best in situa-
tions requiring maximum pressure on
the pedal ("panic stop"). Do not let up
on the brake pedal even after it starts
pulsating. Since the vehicle maintains
steering responsiveness, you can
nevertheless avoid possible obstacles
with a minimum of steering effort.
The ABS closed-loop control circuit
cycles in fractions of a second. Pulsa-
tion at the brake pedal shows you that
ABS is active, that you are braking
within the ABS' braking range and that
you are thus pushing the limit of the
system. In addition, a pulsation Ð a
result of the control function cycles Ð
indicates to the driver that the vehicle
speed should be reduced to adapt to
road surface conditions when there is
reduced traction and grip between tires
and road surface (slippery road
surface).
On road surfaces with a loose surface
layer over a firm base, e.g. on gravel or
snow, as well as when driving with
snow chains on, braking distances may
be longer for a locked-wheel condition.
However, ABS continues to provide
enhanced vehicle stability and steering
response under these conditions.
Information for your safetyNot even ABS can suspend the laws of
physics. The consequences of hitting
the brakes when there is inadequate
distance between vehicles, when the
vehicle is driven at excessive speeds
through curves, or during aquaplaning,
remain the driver's responsibility. You
should never allow the added safety of
ABS to lull you into a false sense of
security, or mislead you into taking risks
that could affect your own safety and
that of others.
Do not make any modifications to
the ABS system.
Service procedures on ABS are to be
performed by authorized technicians
only.< Antilock Brake System (ABS)/
Cornering Brake Control (CBC) CBC is an advanced engineering
design of the ABS. When braking while
cornering at high speed or braking
during high lateral acceleration, or
when braking during a lane change,
vehicle stability is improved and
steering response is enhanced.

Antilock Brake System (ABS)In the event of a malfunction
If the ABS warning lamp does
come on, refer to page 21. The
brake system will then function
the same as on vehicles without ABS.
However, have the brake system
checked by your BMW center as soon
as possible. To prevent undetected
defects and cumulative faults from
adversely affecting the brake system,
refer any problems to your BMW center
at the earliest opportunity.
ABS warning lamp for Canadian
models.
If the brake warning lamp
comes on together with the
indicator lamps for ABS and
DSC, refer to page 21, the entire
ABS, CBC and DSC control
system has failed. Continue
driving cautiously and defen-
sively. Avoid full brake applica-
tions. This could cause the vehicle to
lose stability and you might no longer
be able to control it.
Have the system checked by your BMW
center as soon as possible.

Disk brakesDisk 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
operating conditions where brake appli-
cations are less frequent, there is an
increased tendency for corrosion of the
disks and accumulation of contamina-
tion on the brake pads. This occurs
because the minimal pressure that must
be exerted by the pads to clean the
disks by brake applications is not
reached.
If the brake disks are corroded, they will
tend to respond to braking with a
pulsating effect which even extended
application will fail to cure.
For your own safety: use only
brake pads which BMW has
approved for your specific vehicle
model. BMW cannot evaluate non-
approved brake pads to determine if
they are suited for use, and therefore
cannot ensure the operating safety of
the vehicle if they are installed.<
Driving notes While driving on wet roads or in heavy
rain, it is a good idea to apply light
pressure to the brake pedal every few
miles or kilometers. Watch traffic condi-
tions to ensure that this maneuver does
not endanger other road users. The
heat which is generated by the brake
applications helps to dry the brake
pads and disks.
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 should ever fail, pump
the brakes if possible (refer to
page 109).
Extended or steep mountain descents
should be driven in the gear in which
only minimal periodic brake application
is required. This avoids excessive strain
on the brakes and possible
impairment of the braking effect. Stay
within the allowable engine speed
range. For further information, refer to
page 69.
The braking effect of the engine can be
further increased by downshifting, into
first gear, if necessary. 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). Pause before
repeating the brake 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
depressed, with the shift lever in
neutral or with the engine shut off. The
engine does not provide any braking
effect with the transmission in neutral or
with the engine shut off.
Do not allow floor mats, carpets or any
other objects to protrude into the area
around the brake pedal, the clutch or
the accelerator which could obstruct
their freedom of movement.<

Winter operationBrakingWinter road conditions substantially
reduce the amount of traction available
between the tires and the road surface;
the resulting increase in braking
distance is considerable and should
always be kept in mind.
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
increase the pressure, reduce the pres-
sure when the wheels lock, reapply
pressure etc.
This staggered braking procedure will
reduce stopping distances while
helping you maintain steering control.
You can then attempt to steer around
hazards after you have reduced pres-
sure on the brake pedal. Do not shift down on slick road
surfaces. Doing so could cause
the rear wheels to lose traction and
skid, which could result in the loss of
vehicle control.<
Depress the clutch during hard
braking on road surfaces which
provide only poor or uneven traction.<
Skid control Depress the clutch and let up on the
gas. Countersteer carefully and attempt
to regain control of the vehicle.
ParkingEngage first or reverse gear. Depending
on the steepness of the incline, you can
apply the parking brake as well. In order
to prevent the parking brake pads from
locking due to frost or corrosion, dry
them by gently applying the parking
brake as the vehicle is coming to a
stop. Make sure that following traffic
is not endangered.
The brake lamps do not light up
when the parking brake is
applied.<
