2001 BMW 325XI parking brake

64n
Parking brake To engageThe parking brake is designed primarily
to prevent the vehicle from rolling when
it is parked. It operates against the rear
wheels.
The lock engages automatically when
you lift the lever. The indicator lamp in
the instrument cluster lights up in igni-
tion key position 2. Refer to page 21.To releasePull up slightly on the lever, press the
button (arrow) and lower the lever.460us024
If, in exceptional circumstances,
it should be necessary to engage
the parking brake while the vehicle is
in motion, do not pull the lever with
excessive pressure. Keep your thumb
pressed against the release button
while carefully pulling the lever up to
apply moderate pressure.
Excessive pressure can lead to over-
braking and loss of traction (fishtailing)
at the rear axle.
The brake lamps do not come on when
the parking brake is engaged.
Vehicles with manual transmission:
Always engage the parking brake
when parking on slopes and inclined
surfaces, since even placing the
lever in 1st gear or reverse may not
provide adequate resistance to rolling.
Vehicles with automatic transmission:
Place the selector lever in "Park."<
To avoid corrosion and one-sided
braking, apply the parking brake lightly
from time to time when coasting to a
standstill (at a traffic signal, for
instance), provided that it is safe to do
so.

Manual transmission Press the clutch pedal all the way down
each time you shift, pressing the
manual-shift gear lever into its proper
end position.
Depress the clutch when starting the
vehicle, too, otherwise, lockout will
prevent the engine from starting if the
clutch is not depressed.
The shift lever's neutral plane (dot in the
illustration) is located between 3rd and
4th gears.
When shifting from each gear into
"Neutral," the shift lever returns auto-
matically to this neutral position
because of its spring loading.360de044
Reverse Select "Reverse" only when the vehicle
is at a complete stop. Press the shift
lever to the left to overcome the resis-
tance.
As you do this, the backup lamps will
turn on automatically when the ignition
key is in position 2.
Do not hold the vehicle in place on
slopes by slipping or "riding" the
clutch. Use the parking brake instead.
Otherwise, riding the clutch will cause
tremendous wear and tear to the
clutch.<

Automatic transmission with Steptronic
*
You have the option of driving with a
normal automatic transmission or
switching to manual.
When you move the selector lever from
the "D" position to the left into the M/S
range, the performance-oriented shift
programs of the automatic transmission
are engaged. As soon as you briefly
touch the selector lever in the "+" or "Ð"
direction, Steptronic changes the gear.
The manual mode is engaged. When-
ever you want to use automatic again,
just shift the selector lever toward the
right to position D.
The automatic transmission with Step-
tronic is equipped with ATC (Adaptive
Transmission Control). ATC reacts with
precision to your individual driving style
and the current driving conditions. It is
for this reason that various shift
programs are used.
For additional details concerning the
ATC, please refer to the chapter
"Advanced technology" on page 178.
Selector lever positions
P R N D M/S + Ð
Starting the engineThe engine can only be started in
selector lever positions P ("Park") or N
("Neutral").Range selectionA detent prevents inadvertent shifts into
certain selector lever positions. To
disengage the detent, press the button
on the front of the shift knob (arrow).463de061
While the vehicle is stationary and
before shifting out of "Park" or
"Neutral," depress the footbrake in
order to disengage the selector lever's
lock mechanism (Shiftlock).
Hold the footbrake down until starting
off. Otherwise the vehicle will "creep"
when a drive position is engaged.<
If you leave the vehicle with the
engine running, move the selector
lever to the "Park" or "Neutral" position
and apply the parking brake. If you fail
to do this, the vehicle could move.
Do not leave the vehicle unattended
with the engine running. An unattended
vehicle with a running engine repre-
sents a major potential safety hazard.<

stationary. The transmission locks to
prevent the rear wheels from turning.R ReverseSelect only when the vehicle is
stationary.N NeutralSelect only if your journey is interrupted
for a long period.

Automatic transmission with Steptronic
*
In the following situations, the Step-
tronic "thinks" for you in the manual
mode:
>In order to prevent the engine from
overrevving, the transmission shifts
automatically to the next higher gear
just before the engine speed cutoff
point.
>If you do not do anything to inter-
vene, it will automatically downshift
at lower speeds.
>In kickdown, it will downshift into
the lowest gear possible, depending
on the engine speed.
>According to the situation, for
instance in wintry conditions, the
vehicle can be started in 2nd or
3rd gear.

Electronic transmission control
module
If the indicator lamp comes on,
there is a malfunction in the
transmission system.
Bring the vehicle to a stop, select trans-
mission position "P," set the parking
brake and turn the engine off (ignition
key to position 0).
Wait a few seconds, then start the
engine.
If the indicator lamp goes out after a
few seconds, normal transmission
performance has been restored. You
may continue to drive as usual.
If the indicator lamp does not go out,
all selector lever positions can still be
selected, however in the forward
positions the vehicle has limited
performance as it drives only in 3rd
and 4th gear.
If this happens, avoid extreme engine
loads and consult the nearest BMW
center.
Do not work in the engine
compartment when a drive gear
(forward or reverse) is engaged. If you
do this, the vehicle could move.<
For towing or jump-starting, refer to the
information beginning on page 173.

To ensure that your vehicle provides
maximum economy throughout a long
service life, we request that you comply
with the following recommendations.
Engine and differentialUp to 1,200 miles (2,000 km):
Drive at varying engine speeds and
road speeds, but do not exceed
4,500 RPM or a road speed of 100 mph
(160 km/h) during this initial period.
Obey your local and state maximum
speed limits.
Do not apply 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.
Follow the same break-in procedure if
either the engine or the differential is
replaced in the future.
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).
Obey your local and state maximum
speed limits.
When the vehicle is operated on
wet or slushy roads, a wedge of
water may form between the tire and
the road surface. This phenomenon is
referred to as aquaplaning, or hydro-
planing, and can lead to partial or
complete loss of traction, vehicle
control and braking effectiveness.
Reduce your speed on wet roads.<
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
traffic 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
vehicle with the engine off Ð when
towing, for example Ð substantially
higher levels of pedal force will be
required to brake the vehicle. optimally after about 300 miles
(500 km). Engage the gears carefully
during the break-in period.

Catalytic converter Antilock Brake System (ABS)
Be sure to comply with the
instructions above to prevent
unburned fuel from reaching the cata-
lytic convertor. If you do not, the cata-
lytic converter could respond by
overheating, leading to serious
damage.
Extreme temperatures occur at the
catalytic converter on this and every
catalyst-equipped vehicle. Heat shields
are installed adjacent to some sections
of the exhaust system. Never remove
these shields; do not apply under-
coating to their surfaces. When driving,
standing at idle, and parking the
vehicle, take extra care to avoid contact
between the exhaust system and flam-
mable materials (grass, hay, leaves,
etc.). Such contact could lead to a fire,
resulting in serious personal injury and
property damage.<
The concept ABS enhances active safety by helping
to prevent the wheels from locking
under braking. This is because 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.
The system can achieve the shortest
braking distances possible under most
conditions (on straight-aways and in
curves, on 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
road surfaces, snow, ice).Braking with ABSThe system becomes operative once
the vehicle exceeds a speed of approx.
6 mph (10 km/h). Below approx. 4 mph
(6 km/h), it is once again 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.If you are in a situation that requires full
braking, you will exploit the full benefits
of the ABS system if you apply
maximum brake pressure ("panic
stop"). Since the vehicle maintains
steering responsiveness, you can avoid
possible obstacles with a minimum of
steering effort, despite the full brake
application.
The ABS system closed-loop control
circuit cycles in fractions of a second. A
pulsation at the brake pedal, together
with the sounds associated with the
hydraulic controls, tells you that the
brake system is within its maximum
limit range and reminds you that you
should adapt road speed to the road
conditions.
On road surfaces that have a loose
surface layer on a firm base with good
traction (on gravel or snow, for
example), or when snow chains are
mounted, braking distances may be
longer than with locked wheels.
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. ABS cannot prevent the

Brake systemBrake fluid level
If the brake warning lamp
comes on and the parking brake
has been released:
The brake fluid level is too low in the
reservoir (refer to page 143).
If the brake fluid level is too low and
brake pedal travel has become notice-
ably longer, there may be a defect in
one of the hydraulic circuits of the brake
system.
Brake warning lamp for Cana-
dian models.
Proceed to the nearest BMW
center. Higher brake application
pressure may be necessary under these
conditions, and brake pedal travel may
be significantly longer. Please
remember to adapt your driving style
accordingly.<
Brake pads
If the warning lamp for the brake
pads lights up:
The brake pads have reached
their minimum pad thickness. Proceed
to the nearest BMW center as soon as
possible to have the pads replaced.
For your own safety: use only
brake pads that BMW has
approved for your particular 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.<

Winter operation Power steering
Do not shift down on slick road
surfaces. Doing so could cause
the rear wheels to lose traction and
skid, resulting in a loss of vehicle
control.<
Depress the clutch during hard
braking on road surfaces that
provide only poor or uneven traction.<
Skid control Depress the clutch and release the
accelerator pedal, or place the selector
lever of the automatic transmission into
the "Neutral" position. Countersteer
carefully and attempt to regain control
of the vehicle.
ParkingEngage 1st or reverse gear. If your
vehicle is equipped with an automatic
transmission, place the selector lever in
Park. On vehicles with manual trans-
mission, also apply the parking brake
when parking on inclined surfaces. In
order to prevent the parking brake
linings 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.<
If the steering response changes, e.g.
high steering effort:
Contact a BMW center to have this
system inspected.
If the power steering fails,
increased effort will be required to
steer the vehicle.<
