flow into the tank and the "Service
Engine Soon" lamp may come on.<
Press on the rear edge of the fuel filler
door to open and close it.
To unlock the fuel filler door if the
central locking system malfunctions,
refer to page 172.
When handling fuels, comply with
all of the applicable safety precau-
tions and regulations pertaining to fuels.
Never carry spare fuel containers in
your vehicle. Whether empty or full,
these containers can leak, cause an
explosion, or lead to fire in the event of
a collision.<

Simple and environmentally
friendly
Open the filler cap carefully to
prevent fuel from spraying out.
Fuel spray may cause injury.<
Keep the filler cap in the bracket
attached to the fuel filler door.
When refueling, insert the filler nozzle
completely into the filler pipe. Pulling
the nozzle out of the pipe during refu-
eling
>results in premature pump shutoff
>and will reduce the effect of the vapor
recovery system on the pump.
The fuel tank is full, whenever the fuel
nozzle shuts off the first time, as is
specified for proper service.
Tank capacity: refer to page 195.

Starting the engine Switching off the engine Do not press the accelerator pedal
while starting the engine.
Do not actuate the starter for too
short a time, but do not turn it for
more than approx. 20 seconds. Release
the ignition key immediately when the
engine starts.
Do not allow the engine to warm up by
leaving it running while the vehicle
remains stationary. Instead, begin
driving immediately at a moderate
engine speed.<
If the engine does not start on the first
attempt (if it is very hot or cold, for
instance):
>Press the accelerator pedal halfway
down while engaging the starter.
Cold start at extremely low tempera-
tures, from approx. +5 7 (-15 6)
and at elevations above 3,300 feet
(above 1,000 meters):
>On the first start attempt, engage the
starter for a longer period (approx.
10 seconds).
>Press the accelerator pedal halfway
down while engaging the starter.
Engine idle speed is controlled by the
engine computer system. Increased
speeds at startup are normal and
should decrease as the engine warms
up. If engine speed does not decrease,
service is required.
To prevent the battery from
discharging, always deactivate elec-
trical devices that are not in use. Switch
the ignition off when the vehicle is not
being driven.Turn the ignition key to position 1 or 0.
Do not remove the ignition key
while the vehicle is still moving.
If you did so, the steering lock would
engage when the steering wheel is
turned.
When you leave the vehicle, always
remove the ignition key and engage the
steering lock.
Vehicles with manual transmission:
Always engage the parking brake when
parking on slopes and inclined
surfaces. 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."<

Fuel gauge Temperature gauge Service Interval Display When you switch on the ignition, the
indicator lamp comes on briefly to
confirm that the system is stationary.
Once the indicator lamp begins to light
up continuously, there are still approx.
2 gallons (8 liters) of fuel in the fuel
tank.
Tank capacity: refer to page 195.
If the tilt of the vehicle varies (extended
driving in mountainous areas, for
example), there may be slight fluctua-
tions of the needle.
Fill the fuel tank well before it is
empty. Driving to the last drop of
fuel can result in damage to the engine
and/or the catalytic converter.<460us081
BlueThe engine is still cold. Drive at
moderate engine and vehicle speeds.RedWhen you switch on the ignition, the
indicator lamp comes on briefly to
confirm that the system is operational.
If the lamp comes on while operating
the vehicle: the engine is overheated.
Stop and switch the engine off immedi-
ately and allow it to cool down.Between the blue and red zonesNormal operating range. It is not
unusual for the needle to rise as far as
the edge of the red zone in response to
high outside temperatures or severe
operating conditions. Checking coolant
level: refer to page 142.460de082
Remaining distance for serviceThe displays shown in the illustration
appear for a few seconds from ignition
key position 1 or after the engine is
started.
The next service due appears with the
message OILSERVICE or INSPECTION,
together with the remaining distance
before the service is due.
The computer bases its calculations of
the remaining distance on the previous
driving style.
A flashing message and a "Ð" in front of
the number mean that the service
interval has already been exceeded by
the distance shown on the display.
Please contact your BMW center for an
appointment.460us112

DSC Ð BMW 325xi, 330xiReactivating the DSCPress the button again; the indicator
lamp goes out.
The laws of physics cannot be
repealed, even with DSC. It will
always be the driver's responsibility to
drive in a manner that matches road
conditions. This is why you should not
use the additional safety margin the
system provides as an excuse to take
risks.
Whenever the DSC has been switched
off, it will not perform any stabilizing
intervention.
Do not make any changes to the DSC.
Allow only authorized technicians to
perform service procedures on the
DSC.<
For additional details concerning DSC,
please refer to the chapter "Advanced
technology" on page 179.

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.

Antilock Brake System (ABS)consequences of brake applications
with inadequate clearances for safety
between vehicles, when exceeding the
speed limit, or the risks involved when
aquaplaning occurs. Responsibility for
these types of situations remains in the
hands (and at the feet) of the driver. You
should never allow the added safety of
ABS to mislead you into taking
increased risks.
Do not make any modifications to
the ABS system. Service proce-
dures on ABS are to be performed by
authorized technicians only. Cornering Brake Control (CBC) CBC is an advanced engineering devel-
opment of ABS. When braking during
cornering with high lateral accelera-
tion, or when braking during a lane
change, vehicle stability is improved
and the steering response is enhanced.In the event of a fault
If the ABS in the instrument
cluster lights up, refer to
page 22. The brake system then
reverts to conventional operation as on
vehicles without ABS. However, have
the brake system checked by your
BMW center as soon as possible. To
prevent undetected defects and cumu-
lative faults from adversely affecting the
brake system, refer any problems to
your BMW center at the earliest oppor-
tunity.
ABS warning lamp for Canadian
models.
If the brake warning lamp
comes on together with the indi-
cator lamps for ABS and
ASC+T/DSC, refer to page 21,
the entire ABS, CBC and
ASC+T/DSC control system has
failed. Continue driving
cautiously and defensively.
Avoid full brake applications. This could
cause the vehicle to lose stability and
you might no longer be able to control
it.
Have the system checked as soon as
possible by your BMW center.
CBC, ABS and ASC+T/DSC
and
ADB/ADB-X/DBC indicator and
warning lamps for Canadian
models.
Dynamic Brake Control (DBC)*DBC is included in the DSC, refer to
information beginning on page 84.
If you step on the brake rapidly, this
system automatically produces
maximum braking force boost and thus
helps to achieve the shortest possible
braking distance during "panic stops."
All of the benefits of the ABS system
are exploited under these circum-
stances.
Do not reduce the pressure on the
brake pedal for the duration of the
brake application. When the brake
pedal is released, the DBC is deacti-
vated.
In the event of a malfunction,
the yellow brake warning lamp
comes on. Normal braking effi-
ciency and ABS are still fully available.
Have the system checked and repaired
at your BMW center as soon as
possible.
Please observe the section "Infor-
mation for your safety" concerning
the ABS system, which also applies to
the DSC system.<
