Master keys with remote control
Each master key contains a battery that is auto-
matically charged in the ignition lock during
driving. Use the master key at least twice a year
in order to maintain its charge condition.
Depending on which master key is detected by
the vehicle during unlocking, different settings
in the vehicle are requested and executed, refer
to Key Memory.
Spare key
For storage in a safe place, such as in your wal-
let.
This key does not fit in the lock of the glove
compartment. This is an advantage, e.g. when
valet parking. The key is not intended for con-
stant use.
New keys
You can get replacement keys or spare keys
from your BMW Sports Activity Vehicle Center.

How the system functions
You have probably frequently wished that you
could configure individual functions of your
vehicle to reflect your own personal require-
ments. In developing your vehicle, BMW has
incorporated a number of options for personal
adjustment. You can have these programmed
at your BMW Sports Activity Vehicle Center.
There are vehicle-related and person-related
adjustments: Vehicle Memory and Key Mem-
ory. You can configure up to four different basic
adjustments for four different persons. The only
requirement is that each person use his or her
own master key with remote control.
When your vehicle is unlocked with the remote
control, the vehicle recognizes the individual
user by means of a data exchange with the key,
and makes adjustments accordingly.
In order for you to distinguish between the mas-
ter keys with remote control, color-coded
decals are supplied together with the keys.
What the system can do
Ask your BMW Sports Activity Vehicle Center
about the possibilities of Vehicle Memory and
Key Memory.
You will see this symbol throughout the
Owner's Manual. It is to remind you at
appropriate places of the settings that are avail-
able to you.<
Following configuration of memory func-
tions, vehicle operation may differ from
the description in the Owner's Manual. Should
you wish to sell your BMW some day, please
remember to have the memory functions reset
to the factory default settings.<

Protect valve stems with valve stem
seal caps from dirt and contamina-
tion. Dirt in valve stems is a frequent source
of gradual air loss.<
4.Reinitialize the Flat Tire Monitor
* or reset
the Tire Pressure Monitor
*, refer to
pages53, 54.
Do not initialize the Flat Tire Monitor
when driving with a compact wheel.<
5.Replace the defective tire as soon as possi-
ble and have the new wheel/tire balanced.
Driving with compact wheel
Drive reservedly and do not exceed a speed of
50 mph/80 km/h.
Mounting the compact wheel can change the
driving characteristics. For example, it can
reduce tracking stability during braking, extend
braking distances, and alter self-steering char-
acteristics in the limit range. With winter tires,
these characteristics are more pronounced.
Only one compact wheel may be
mounted. You should re-equip with
wheels and tires of the original size as soon as
possible.<
Vehicle battery
Maintenance
The battery is 100 % maintenance-free, i.e., the
electrolyte will last for the life of the battery
when the vehicle is operated in a temperate cli-
mate. Your BMW Sports Activity Vehicle Center
will be happy to advise you on all questions con-
cerning the battery.
Warning lamp
The warning lamp lights up. The battery
is no longer being charged. The alterna-
tor V-belt is defective or there is a mal-
function in the charge current circuit of the
alternator. Have the system checked immedi-
ately.Do not continue driving if the V-belt is
defective. The engine could be damaged
due to overheating.
Moreover, an increased amount of force is
required for steering if there is a sharp drop in
the onboard supply voltage.<
Charging battery
Charge the battery in the vehicle only when the
engine has been switched off. For connections,
refer to Jump starting on page114.
Disposal
Have old batteries disposed of following
replacement at your BMW Sports Activity
Vehicle Center or bring them to a collection
point. Maintain the battery in an upright position
for transport and storage. Always secure the
battery to prevent it from tipping over during
transport.<
Power failure
After a temporary power supply interruption,
some equipment is subject to limited use and
must be reinitialized. Individual settings are also
lost and must be updated again:
>Panorama glass sunroof
It may be only possible to raise the sunroof.
The system must be initialized, refer to
page24.
>Power windows
The pinch protection system must be reini-
tialized, refer to page23.
>Seat and mirror memory
The positions must be stored again, refer to
page30.
