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 page34.

please contact your BMW center, which is
also your source for replacement keys.<

Maintenance
The BMW Maintenance
System
The BMW Maintenance System serves to
retain the operating and road safety of your
BMW. The service schedule also includes
operations related to the vehicle's comfort
and convenience features, such as
replacement of the filters for the inside air.
The aim is to optimize maintenance with
regard to reducing the cost of running the
vehicle.
Should the day come when you decide to
sell your BMW, you will find that a complete
dealer service history is an asset of inesti-
mable value.
CBS Condition Based Service
Sensors and special algorithms take the
different driving conditions of your BMW
into account. As a result, Condition Based
Service determines the current and future
maintenance requirements. By letting you
define a service and maintenance regimen
that reflects your own individual require-
ments, the system forms the basis for trou-
ble-free driving.
The service requirement display, refer to
page82, shows you the times or distances
remaining until the deadlines for selected
service and maintenance procedures, as
well as legally-mandated inspections:
>Engine oil
>Brakes, separate for front and rear
>Microfilter/activated-charcoal filter >Brake fluid
>Spark plugs
>Vehicle check
>Coolant
>Legally prescribed inspections depend-
ing on national regulations.
Your vehicle stores this information contin-
uously in the ignition key while the vehicle
is being driven. After accessing the data
stored in the vehicle key, your BMW service
advisor is able to suggest precisely the
right array of service procedures for your
own individual vehicle. You should there-
fore hand over to the BMW service advisor
the key you last used to drive when you
take your vehicle for service.
Storage periods with the battery dis-
connected are not taken into account
by the CBS maintenance system. Have the
time-dependent service and maintenance
operations, such as brake fluid and cool-
ant, and if necessary engine oil and the
micro/activated charcoal filter, updated by
a BMW center.<

Booklet for US models and
Warranty and Service Guide Booklet
for Canadian models
Additional information on required service
and maintenance operations is contained
in the Service and Warranty Information
Booklet for US models and Warranty and
Service Guide Booklet for Canadian mod-
els.
BMW recommends having mainte-
nance and repairs carried out by your
BMW center.
Make sure that the maintenance operations
are confirmed in the Service and Warranty
Information Booklet for US models and
Warranty and Service Guide Booklet for
Canadian models. These entries serve as
proof of the regular maintenance per-
formed on your BMW.<

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-ended spanners.
Windshield wiper blades
To replace the blades, start by folding the
wipers out and away from the windshield,
refer to page73.
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 proce-
dures, BMW recommends having the
replacements carried out at your BMW
center.
Never touch the glass of new bulbs
w i t h y o u r b a r e f i n g e r s , a s e v e n m i n u t e
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.<
Engine compartment, left side:
Turn the quick-release snaps 905 counter-
clockwise and remove the cover.
After replacing the bulb return the cover to
its original position and press the quick-
release clamps down.

Battery
Battery care
The battery is 100 % maintenance-free, i.e.,
the electrolyte will last for the life of the bat-
tery when the vehicle is operated in a tem-
perate climate. Your BMW center will be
happy to advise you on all questions con-
cerning the battery.
Charging battery
Only charge the battery in the vehicle via
the terminals in the engine compartment
with the engine off. Connections, refer to
Jump-starting on page210.
Battery switch
Before storing the vehicle for an extended
period of several weeks or more, slide the
battery switch located behind the trim
panel on the right side of the luggage com-
partment to OFF. This reduces the current
flow from the battery for the period during
which the vehicle remains parked. A mes-
sage appears in the Check Control. Please
take note of the supplementary information
provided on the Control Display.
Disposal
Have old batteries disposed of follow-
ing replacement at your BMW center
or bring them to a collection point. Maintain
the battery in an upright position for trans-
port and storage. Always secure the battery
to prevent it from tipping over during trans-
port.<
Power failure
Following a temporary power failure, e.g. in
the case of a flat battery, some equipment
is subject to restricted use and must be
reinitialized. Individual settings are also lost
and must be updated again:
>Seat, mirror and steering wheel memory
The positions must be stored again,
refer to page55
>Time and date
Must be updated again, refer to
page90
>Radio
Stations must be stored again, refer to
page 154
>Navigation system
The operability must be waited for, refer
to page130.
Fuses
Never attempt to repair a blown fuse,
and do not replace a defective fuse
with a substitute of another color or amper-
age rating, as this could lead to a circuit
overload, ultimately resulting in a fire in the
vehicle.<
Spare fuses are located on the fuse strip in
the glove compartment; plastic tweezers
can be found at the fuse holder in the lug-
gage compartment.
In glove compartment
Press the tab on the cover to the front, then
fold up the cover.

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.
Therefore, check the expiration dates of the
contents regularly and replace the contents
concerned in good time if necessary. You
can find replacements in any pharmacy.
Comply with legal requirements requiring
you to carry a first-aid kit 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 terminal
clamps.
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 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.
1.Remove the cover of the BMW auxiliary
terminal for jump-starting
2.Connect one terminal clamp of the pos-
itive/+ jumper cable to the positive ter-
minal of the battery or an auxiliary termi-
