Central locking system
The concept
The central locking system is ready for
operation whenever the driver's door is
closed. This simultaneously engages and
releases the locks on the following:
>Doors
>Luggage compartment lid
>Fuel filler door.
The central locking system can be oper-
ated from the outside
>via the remote control
>via the driver's door lock
>with Comfort Access via the door han-
dle
and from inside via the button for the cen-
tral locking system.
When the system is locked from inside, the
fuel filler door remains unlocked, refer to
page 36.
The anti-theft system is automatically acti-
vated whenever you activate the central
locking system from outside the vehicle.
The alarm system is armed/disarmed at the
same time.
In an accident, the central locking system
automatically unlocks the vehicle. In addi-
tion, the hazard warning flashers and inte-
rior lamps switch on.
Opening and closing:
from outside
Using the remote control
When you engage/release the vehicle's
locks, you simultaneously activate/deacti-
vate the anti-theft system, arm/disarm the
alarm system
and switch the interior lamps
on/off. In addition, the remote control offers you
another function:
>Panic mode
In case of danger, you can trigger an
alarm.
You can have various confirmation
signals programmed into the system
to verify that the vehicle has been locked
securely.<

and alarm system
2To lock and secure, switch off tilt alarm
sensor and interior motion sensor,
switch on interior lamps and door-
mounted proximity lamps
3To open the luggage compartment lid
4To switch on interior lamps, activate
panic mode
Because any persons or animals left
unattended in a parked vehicle could
lock the doors from the inside, you should
always keep the remote control with you;
this precaution ensures that you will remain
able to unlock the vehicle from the outside
at all times.<
When it is no longer possible to lock
the vehicle via the remote control, the
battery is discharged. Use this remote con-
trol during an extended drive; this will
recharge the battery, refer to page 32.
In the event of a system malfunction,
please contact your BMW center, which is
also your source for replacement keys.<

Replacing components
Onboard tool kit
The onboard tool kit is located in the lug-
gage compartment lid.
Loosen the wingnut to open.
The adapter for the spare key can be stored
beneath the open-end wrenches.
Windshield wiper blades

Lamps and bulbs
The lamps and bulbs are essential factors
contributing to the safety of your vehicle.
Therefore, comply fully with the following
instructions during bulb replacement.
If you are not familiar with the specified
procedures, BMW recommends having the
replacements carried out at your BMW
center.
Never touch the glass of new bulbs
with your bare fingers, as even minute
amounts of contamination will burn into the
bulb's surface and reduce its service life.
Use a clean cloth, napkin, etc., or hold the
bulb by its metal socket.<
You can obtain a selection of replacement
bulbs at your BMW center. To prevent short circuits, before
working on any electrical system,
equipment or accessory you should always
switch it off and disconnect the cable from
the battery's negative terminal before start-
ing.
To avoid possible injury or equipment dam-
age when changing bulbs, observe any
instructions provided by the bulb manufac-
turer.<
When maintaining the headlamps,
please comply with the instructions in
the separate Caring for your vehicle bro-
chure.<
Headlamps
For checking and adjusting headlamp
aim, please contact your BMW cen-
ter.<

Giving and receiving assistance
Warning triangle*
The warning triangle is conveniently stored
in the onboard tool kit mounted on the
inside of the luggage compartment lid.
Comply with legal requirements
requiring you to carry a hazard warn-
ing triangle in the vehicle.<
First-aid kit*
You will also find the first-aid kit in the
onboard tool kit's container.
Some of the articles contained in the
first-aid kit have a limited service life.

Always comply with laws requiring a first-
aid kit to be carried in the vehicle.<
Jump-starting
When your battery is discharged you can
use two jumper cables to start your vehicle
with power from the battery in a second
vehicle. You can also use the same method
to help start another vehicle. Use only
jumper cables with fully-insulated clamp
handles.To avoid the risk of potentially fatal
injury, always avoid all contact with
electrical components while the engine is
running. Carefully adhere to the following
sequence, both to prevent damage to one
or both vehicles, and to guard against pos-
sible personal injury.<
Preparing
1.Check whether the battery of the other
vehicle has a voltage of 12 Volts and
approximately the same capacitance
in Ah. This information can be found on
the battery
2.Switch off the engine of the support
vehicle
3.Switch off any electrical systems and
components in both vehicles.
Ensure that no contact exists
between the bodywork on the two
vehicles, otherwise there is a danger of
short circuits.<
Connecting the jumper cables
To avoid personal injury from sparks,
always observe this sequence when
connecting jumper cables.<
Your BMW is equipped with an auxiliary
terminal specifically designed for jump-
starting. It is located within the engine
compartment, refer to arrow 1 in the illus-
tration. The symbol + is embossed on the
cover.
