Opening and closing
The key set
1Master keys with remote control.
They specify the functions of the Key
Memory. In the process individual func-
tions of your vehicle can behave differ-
ently depending on the key used, see
further below.
To differentiate, you can mark the keys
with remote controls using the color-
coded decals you received on taking
delivery of the vehicle
There is an extended-life battery
in every master key with remote
control which is charged automatically
in the ignition lock as you drive.
If you have any master keys with remote
control that are not used on a regular
basis, you should therefore remember
to recharge these units by using them
to drive the vehicle for an extended
period at least every six months, also
refer to page 28.<
2Spare key for storage in a safe place,
such as in your wallet.
The locks for the luggage compartment
lid and the hotel function, refer to
page 30, cannot be operated with this
key. This is an advantage in a hotel, for
example. The key is not intended for
constant use
Replacement keys
Additional or replacement keys are avail-
able at your BMW center.
Key Memory
How the system functions
Doubtless you have often reflected on how
great it would be if you could configure
your vehicle's various adjustment settings
to meet your own personal requirements.
BMW has designed several freely select-
able options into the vehicle during its
development. You can set these as desired
via the Control Center.
You can have up to four different basic set-
tings adjusted for four different persons for
the specific keys. The only requirement is
that each person uses his or her own mas-
ter key with remote control.
When your vehicle is unlocked with the
remote control, the vehicle recognizes the
individual key by means of a data exchange
and makes adjustments accordingly.
Examples of Key Memory functions
>Automatic adjustment of the driver's
seat
>Locking the vehicle after moving off
>When unlocking with the remote con-
trol, either unlock only the driver's door
or the entire vehicle
>Activating visual warning for PDC Park
Distance Control
>Resetting volume setting.
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
>Compartment in the front center con-
sole

>Luggage compartment lid
>Fuel filler door.
The central locking system can be oper-
ated from the outside
>via the remote control
>via the door lock
and from inside via the button for the cen-
tral locking system.
If operated from the inside, the fuel filler
door and the compartment in the front
center console are not locked, refer to
page 29.
The anti-theft system is automatically acti-
vated whenever you activate the central
locking system from outside the vehicle.
It prevents the doors from being unlocked
using the safety lock buttons or door han-
dles. The alarm system is armed/disarmed
at the same time.
In the event of an accident, the central
locking system unlocks automatically. The
hazard warning flashers and interior lamps
also switch on.
Opening and closing: from
outside
Using the remote control
When you lock/unlock the vehicle, you
simultaneously activate/deactivate the
anti-theft system, arm/disarm the alarm
system, and switch the interior lamps on/
off.
Protect the remote control against
unauthorized use by handing over
only the spare key, for example when using
hotel valet parking.<
You can find more detailed information on
the alarm system on page 32.
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.<
Unlocking

depending on the setting:
Control Center, for principle details, refer to

6.Select a menu item:

Press the button once to unlock
the entire vehicle
>"Driver's door only"
Press the button once to unlock
only the driver's door and the fuel
filler door.
Press the button twice to unlock the
entire vehicle
7.Press the controller.
Depending on which key you have used to
open the vehicle, the last adjustment is
applied.

Recommended tire sizes and makes
BMW tests certain tire brands for each tire
size, classifies them as road-safe and
approves them. You can find out about
these at specialized dealers or at your
BMW center. Observe any country-specific
regulations, e.g. on making a correspond-
ing entry in the vehicle documents.
The factory-mounted tires have been spe-
cially selected to provide optimized perfor-
mance when installed on your vehicle; if
properly cared for, they will provide a com-
bination of safety and excellent ride com-
fort.
Run-flat tires
In the event of replacement, use run-flat
tires, refer to page 168, as there is no spare
wheel available for flats.
For safety reasons, BMW recom-
mends that you do not have damaged
run-flat tires repaired; they should be
replaced.<
Special characteristics of winter
tires
BMW recommends winter tires for use in
cold winter driving conditions. Although all-
season M+S tires provide better winter
traction than summer tires, they generally
fail to provide the same levels of cold-
weather performance as winter tires.
Run-flat tires
If you switch from summer to winter tires,
or vice versa, use run-flat tires, refer to
page 168, as in the event of a flat tire there
is no spare tire available. Your BMW center
will be glad to advise you.
Observing speed ratings
Never exceed the maximum speed for
which the winter tires are rated.
Unprofessional attempts by laymen to ser-
vice tires can lead to damage and acci-
dents. Have this work performed by skilled
professionals only. The technicians at your
BMW center will be glad to assist you with the required professional knowledge and
specialized equipment.<
Storage
Always store wheels and tires in a cool, dry
place with as little exposure to light as pos-
sible. Always protect tires against all con-
tact with oil, grease and fuels. Do not
exceed the maximum tire inflation pressure
indicated on the side wall of the tire.
Snow chains*
BMW only tests certain snow chains, clas-
sifies them as road-safe and approves
them. Consult your BMW center for more
information. BMW recommends using
these approved, narrow-link snow chains.
These snow chains are approved exclu-
sively for use in pairs on the rear wheels
with the tire size 245/45 R 18.
Observe the manufacturer's instructions
when mounting snow chains.
Do not exceed a vehicle speed of 30 mph/
50 km/h with the chains mounted.
Do not initialize the Runflat Indicator
after mounting snow chains.
When you are driving with snow chains, it
can be beneficial to switch off DSC briefly,
refer to page 77.<

Light-emitting diodes LEDs
Light-emitting diodes installed behind
translucent lenses serve as the light source
for many of the controls and displays in
your vehicle. These light-emitting diodes,
which operate using a concept similar to
that applied in conventional lasers, are offi-
cially designated as Class 1 light-emitting
diodes.
Do not remove the covers, and never
stare into the unfiltered light several
hours, as irritation of the retina could
result.<
Changing a wheel
Your BMW is equipped with run-flat tires as
standard. An immediate wheel change in
the event of a flat tire is therefore no longer
required.
You will recognize run-flat tires by a circular
symbol containing the letters RSC on the
side of the tire, refer to Run-flat tires on
page 167.
If you switch from summer to winter tires,
or vice versa, use only run-flat tires, as in
the event of a flat there is no spare tire
available. Your BMW center will be glad to
advise you.
Also refer to New wheels and tires,
page 168.
Car jacking points
The jacking points for the car jack are
located in the positions shown.
You can obtain a suitable car jack as
an accessory at your BMW center.<
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 glad to advise in
all matters concerning the battery.
Charging battery
Only charge the battery in the vehicle via
the terminals in the engine compartment
with the engine switched off. For the con-
nections, refer to Jump-starting on
page 184.
Disposal
Have old batteries disposed of by
your BMW center or hand them in to a
recycling center. Maintain the battery in an
upright position for transport and storage.
Always restrain the battery to prevent it
from tipping over during transport.<
Power cut
After a temporary power cut, e.g. with a
discharged battery, the features of some
equipment are limited and it has to be rein-
itialized. Individual settings are also lost
