Central locking system Opening and closing Ð from the outside The conceptThe central locking system is ready for
operation whenever the driver's door is
closed. The system engages and
releases the locks on the
>doors
>tailgate and rear window
>fuel filler door.
The central locking system can be
operated
>from outside via the door lock and
using the remote control
>from inside by pressing a button.
Activating the central locking system
from inside does not lock the fuel filler
door (see page 38). When it is actuated
from the outside, the anti-theft system
is activated simultaneously. Both the
door locks and release handles remain
locked. The alarm system is also armed
or disarmed.
If locked from the inside, the central
locking system unlocks automatically in
the event of an accident. But the system
only unlocks those doors that were not
locked separately using the safety
buttons, refer to page 38. In addition,
the hazard warning flashers and interior
lamps come on.
Using the keyOne turn of the key in the driver's door
lock unlocks the driver's door only.
Turning the key a second time unlocks
all of the remaining doors, the tailgate
and the fuel filler door.
You can have a signal set as an
acknowledgment message that
the vehicle is closed correctly.<460de006
Convenience operationYou can also operate the power
windows and sliding/tilt sunroof via the
door lock.
>To open: if the door is closed, hold
the key firmly in the "Unlock" posi-
tion.
>To close: if the door is closed, hold
the key firmly in the "Lock" position.
Watch during the closing process
to be sure that nobody is inadvert-
ently injured. Releasing the key stops
the operation.<Manual operation (in the event of an electrical malfunction)
Turn the key to the extreme left or right
to unlock/lock the door.

Opening and closing Ð from the inside Use this button to operate the central
locking system when the front doors
are closed. The doors and tailgate are
unlocked or locked only. The anti-theft
alarm system is not activated.
If only the driver's door was
unlocked from the outside and
you press on the button, then all the
other doors, tailgate and rear window
as well as the fuel filler door will unlock
if the driver's door is open.
If the driver's door is closed it will be
locked.<
The central locking system can be
locked automatically as soon as
you begin to drive if you desire. You
may also have this adjusted so that it is
specific to keys.<460us007
To unlock and open the doors>Either unlock the doors together with
the button for the central locking
system and then pull each of the
release handles above the armrests,
or
>pull the release handle for each door
twice: the first pull unlocks the door,
and the second one opens it.To engage locks>Use the central locking button to lock
all of the doors simultaneously, or
>press the individual safety lock
buttons down. The fuel filler door
then remains unlocked. As an added
design feature to prevent the driver
from being inadvertently locked out
of the vehicle, the driver's door safety
lock button will not engage as long as
the door is open.
Children might be able to lock the
doors from the inside. For this
reason, take the vehicle's keys with you
so that the vehicle can be opened again
from the outside at any time.<

When you switch on the ignition, the
indicator lamp lights up briefly as a
function check.
Once the indicator lamp stays on
continuously, there are still approx.
2 gallons (8 liters) of fuel left in the fuel
tank.
For fuel tank capacity, refer to page 187.
If the tilt of the vehicle varies (extended
driving in mountainous areas, for
example), there may be slight fluctua-
tions of the needle.
Please refuel early, since driving
to the last drop of fuel can result
in damage to the engine and/or cata-
lytic converter.<460us081

Remaining distance for serviceThe displays shown in the illustration
appear for a few seconds when the
ignition key is in position 1 or after the
engine is started.
The next service due appears with the
message OIL SERVICE or INSPECTION,
together with the remaining distance
before scheduled service.
The computer bases its calculations
of the remaining distance on the rate of
fuel consumption in the period immedi-
ately preceding your data request.
A flashing display and a "Ð" in front of
the number indicate that service is past
due by the number of kilometers/miles
displayed. Please contact your BMW
center for an appointment.460us112

Mode selectionIn ignition key positions 1 and 2, you
can call up information from the
computer using the button in the turn
signal lever. By pressing the button
briefly in the direction of the steering
column, you can call up a new function
for display.
The displays appear in the following
order:
Time, outside temperature, average fuel
consumption, cruising range, average
vehicle speed.
Starting with ignition key position 1, the
last active setting is displayed.460de084
Outside temperature You can change the units of measure-
ment (6/7) for the outside tempera-
ture display by pressing the right-hand
reset button in the instrument cluster
when the temperature display is active. 460us146
Ice warning If the outside temperature drops to
approx. +37.5 7 (+3 6), the computer
automatically switches to the outside
temperature display. In addition, a
signal sounds as a warning and the
display flashes for a brief period.
The warning is repeated whenever the
temperature climbs to at least +43 7
(+6 6) following the last warning, and
then drops back to +37.5 7 (+3 6).
The ice warning does not alter the
fact that surface ice can form at
temperatures above +37.5 7 (+3 6),
on bridges or shaded road surfaces, for
instance.<

Roof-mounted luggage rack
*
Mounting pointsAccess to the mounting points:
To fold up the cover (arrow), please use
the tool which is provided with the
luggage system.
A special luggage system is available
as an option for your BMW. Please
observe the precautions included with
the installation instructions.
Because roof racks raise the center of
gravity of the vehicle when loaded, they
exercise a major effect on its handling
and steering response.
You should therefore always remember
not to exceed the approved roof weight,
the approved gross vehicle weight or
the axle weights when loading the rack.
You will find the specifications under
"Technical Data" on page 186.463de045
Make sure that the load is not too heavy,
and attempt to distribute it evenly.
Always load the heaviest pieces first
(on the bottom). Be sure that adequate
clearance is maintained for raising the
sliding/tilt sunroof, and that objects do
not project into the opening path of the
tailgate.
Secure the roof luggage correctly and
tightly to prevent it from shifting or
being lost during driving (danger to
following traffic).
Drive smoothly and avoid sudden
acceleration or braking. Do not corner
at high speeds.
The roof load increases aerodynamic
resistance, resulting in increased fuel
consumption and additional stresses
on the vehicle's body.

Brakes:
Do not drive with your foot resting
on the brake pedal. Even light but
consistent pedal pressure can lead to
high temperatures, brake wear, and
possibly to brake failure.
Aquaplaning:
When driving on wet or slushy roads,
reduce vehicle speed. If you do not, a
wedge of water may form between the
tires and the road surface. This
phenomenon is referred to as aqua-
planing or hydroplaning. It is character-
ized 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:
When there is water on the roads, do
not drive in it if it is deeper than 1 ft
(30 cm), and then only at walking speed
at the most, otherwise the vehicle can
sustain damage to the engine, the elec-
trical systems and the transmission.
Roll-up cover:
Never use the rear window shelf to
store heavy or bulky objects. If you do
so, such objects could injure vehicle
occupants during braking or evasive
maneuvers or in a crash.
Clothes hooks:
When suspending clothing from the
hooks, ensure that they will not obstruct
the driver's vision. Do not hang heavy
objects on the hooks. If you do, such
objects could pose the risk of personal
injury during braking or evasive maneu-
vers.<The catalytic converter reduces harmful
exhaust emissions, and is designed for
use with unleaded fuel only.
Even minute quantities of lead would be
enough to permanently damage both
the catalytic converter and the system
oxygen sensor.
To ensure efficient, trouble-free engine
operation and to avoid potential
damage:
>Be sure to comply with the scheduled
maintenance requirements.
>Fill the fuel tank well before it is
empty.
>Tow-start only when the engine is
cold. If you attempt to tow-start with
a warm engine, unburned residual
fuel in the catalytic converter could
ignite and cause damage. It is better
to start the vehicle with an outside
starting aid.
>Avoid other situations in which the
fuel is not burned, or burns incom-
pletely, such as engaging the starter
frequently or for extended periods, or
repeated start attempts in which the
engine does not start (stopping and
restarting an engine which is running
properly does not present a problem).
Never allow the engine to run with
any of the spark plug cables
disconnected.

Catalytic converter Antilock Brake System (ABS)
Be sure to observe the instruc-
tions above to prevent unburned
fuel from reaching the catalytic
converter, otherwise, the catalytic
converter could overheat and be
damaged.
High temperatures occur in any vehicle
equipped with a catalytic converter.
Heat shields are installed adjacent to
some sections of the exhaust system.
Never remove these shields; do not
apply undercoating to their surfaces.
When driving, standing at idle, and
parking the vehicle, take care to avoid
contact between the exhaust system
and flammable materials (grass, hay,
leaves etc.). Such contact could lead to
a fire, resulting in personal injury and
property damage.<
The concept ABS enhances active driving safety by
helping to prevent the wheels from
locking under braking. The reason:
locked wheels are dangerous. When the
front wheels slide, the driver loses
steering control over the vehicle. Trac-
tion loss at the rear wheels can cause
the rear end to break into an uncon-
trolled 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.
>Assured ability to steer and
maneuver Ð on the various road
surfaces (asphalt, concrete, dirt,
wet conditions, snow, ice).
The system can achieve the shortest
braking distances possible under most
conditions (on straight-away and in
curves, on asphalt, ice, wet road
surfaces, etc.).
Braking with ABSThe system is operative once the
vehicle exceeds a speed of approx.
6 mph (10 km/h). It is deactivated once
again below approx. 4 mph (6 km/h).
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
nevertheless avoid possible obstacles
with a minimum of steering effort.
The ABS closed-loop control circuit
cycles in fractions of a second. A pulsa-
tion 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.
