The key set
1Every master key with remote control con-
tains an extended-life battery as a power
supply, which is charged automatically in
the ignition lock as you drive. You should
use each master key at least twice a year in
order to maintain the 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 below.
2Spare key for storage in a safe place, such
as in your wallet.
This key does not fit in the locks of the lug-
gage compartment lid and the glove com-
partment. This is an advantage when valet
parking, for example. The key is not
intended for regular use.
New key
Additional or replacement keys are available at
your BMW center.

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 selectable 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 settings
adjusted for four different persons for the spe-
cific keys. The only requirement is that each
person uses his or her own master 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.

2.At the next opportunity, check the air pres-
sure in all four tires.
If the tire inflation pressure in all four
tires is correct, the Flat Tire Monitor
has not been initialized. The system must
then be initialized.<
3.In the event of complete tire pressure loss,
0 psi/0 kPa, or obvious tire damage, you can
estimate the possible distance for contin-
ued driving on the basis of the following
guide values:
>With a light load:
1 to 2 persons without luggage:
approx. 155 miles/250 km
>With a medium load:
2 persons, luggage compartment full, or
4 persons without luggage:
approx. 94 miles/150 km
>With a full load:
4 or more persons, luggage compart-
ment full:
approx. 30 miles/50 km
Drive reservedly and do not exceed a
speed of 50 mph/80 km/h. In the event of
pressure loss, vehicle handling changes. This
includes reduced tracking stability in braking,
extended braking distance and altered natural
steering characteristics.
If unusual vibrations occur while the vehicle is
being driven, this can indicate final failure of the
damaged tire. Reduce speed and stop as soon
as possible. Do not continue driving. Contact
your BMW center.<
Malfunction
The warning lamp lights up yellow and
a message appears on the Control Dis-
play. The Flat Tire Monitor has a mal-
function or has failed. Have the system checked
as soon as possible.
Active steering*
The concept
The active steering is a system that actively var-
ies the steering angle of the front wheels in rela-
tion to the steering wheel movements.
When you are driving in the low road speed
range, e. g. in a town or when parking, the steer-
ing angle increases, i.e. the steering becomes
very direct. In the higher speed range, on the
other hand, the steering angle is reduced more
and more. This improves the handling capability
of your BMW over the entire speed range.
In critical situations, the system can make tar-
geted corrections to the steering angle pro-
vided by the driver and thus stabilize the vehicle
before the driver intervenes. This stabilizing
intervention is simultaneously deactivated
when DSC is switched off, refer to page78.
Malfunction
The warning lamp lights up. The active
steering is no longer operational. At low
speeds, greater steering wheel move-
ments are required, whereas at higher speeds,
the vehicle reacts more sensitively to steering
wheel movements. Have the system checked.
If the warning lamp lights up during the first
engine starting following a power supply inter-
ruption, the system must be activated by being
initialized.
Initializing system
1.Start the engine.
2.With the vehicle stationary, turn the steer-
ing wheel from the straight-ahead position
t o t h e le f t a s f a r a s i t w i ll g o a n d t h e n b a c k t o
the straight-ahead position.
3.Switch off the engine.
When you start the engine again, all the func-
tions of the active steering are available once
again.

Things to remember when driving
108
Hills
To prevent overheating and the resulting
reduced efficiency of the brake system,
drive long or steep downhill gradients in the
gear in which the least braking is required. Even
light but consistent pedal pressure can lead to
high temperatures, brake wear and possibly
even brake failure.<
You can further enhance the engine's braking
action by selecting a lower gear in the automatic
transmission's manual mode, downshifting as
far as first gear on extremely steep stretches,
refer to page56. This strategy helps you avoid
placing excessive loads on the brake system.
Never drive with the clutch pressed or
allow the vehicle to coast with the trans-
mission in Neutral – or with the engine switched
off – there is no engine braking when the trans-
mission is in Neutral, and no power-assist for
brakes and steering when the engine is not run-
ning.
Never allow floor mats, carpets or any other
objects to protrude into the area around the
accelerator and brake pedals and obstruct their
movement.<
Corrosion on brake rotors
When the vehicle is driven only occasionally,
during extended periods when the vehicle is not
used at all, and in operating conditions where
brake applications are less frequent, there is an
increased tendency for corrosion to form on
rotors, while contaminants accumulate on the
brake pads. This occurs because the minimum
pressure which must be exerted by the pads
during brake applications to clean the rotors is
not reached.
Should corrosion form on the brake rotors, the
brakes will tend to respond with a pulsating
effect that even extended application will fail to
cure.
When the vehicle is parked
Condensation forms in the air conditioner sys-
tem during operation, and then exits under the
vehicle.
Traces of condensed water under the
vehicle are therefore normal
.
Before driving into a car wash
To prevent the exterior mirrors on this vehicle
from being damaged, always fold them in by
hand before entering an automatic car wash.
Cargo loading
To avoid loading the tires beyond their
approved carrying capacity, never over-
load the vehicle. Overloading can lead to over-
heating and increases the rate at which damage
develops inside the tires. The ultimate result
can assume the form of a sudden blow-out.<
Determining loading limit
1.Locate the following statement on your
vehicle's placard
*:
The combined weight of occupants
and cargo should never exceed
XXX lbs. or YYY kg. Otherwise, this could
damage the vehicle and produce unstable
vehicle operating conditions.<
2.Determine the combined weight of the
driver and passengers that will be riding in
your vehicle.
3.Subtract the combined weight of the driver
and passengers from XXX lbs. or YYY kg.
4.The resulting figure equals the available
amount of cargo and luggage load capacity.
For example, if the XXX amount equals
1,400 lbs. and there will be five 150 lb. pas-
sengers in your vehicle, the amount of avail-
able cargo and luggage load capacity is
650 lbs.:
1,400 lbs. minus 750 lbs. = 650 lbs.

3.Check and correct the tire inflation pressure
at the earliest opportunity.
Protect valve stems and valve stem
seal caps against dirt and contamina-
tion. Dirt in valve stems is a frequent source
of gradual air loss.<
4.Reinitialize the Flat Tire Monitor, refer to
page80.
5.Replace the damaged tire with a new one as
soon as possible and have the new wheel
balanced.
Driving with compact wheel
Drive reservedly and do not exceed a speed of
50 mph/80 km/h.
The driving characteristics change, for example
reduced track stability on braking, extended
braking distance, and altered self-steering
characteristics in the limit range. In conjunction
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 quickly as
possible.<
Vehicle battery
Battery care
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 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 off. Connections, refer to Jump starting
on page190.
Disposal
Have old batteries disposed of by your
BMW center or hand them in to a recy-
cling 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 failure
After a temporary power loss, the functioning of
some equipment may be limited and require
reinitialization. Individual settings are also lost
and must be updated again:
>Active steering
The system is deactivated and must be ini-
tialized, refer to page81. Until then, the
steering will react differently than usual.
>Seat, mirror and steering wheel memory
The positions must be stored again, refer to
page40.
>Time and Date
The settings must be updated, refer to
page74.
>Radio
Stations must be stored again, refer to
page140.
>Navigation system
You must wait until it becomes operational
again, refer to page128.
Fuses
Never attempt to repair a blown fuse and
do not replace a defective fuse with a sub-
stitute of another color or amperage rating, as
this could lead to a circuit overload, ultimately
resulting in a fire in the vehicle.<
Spare fuses, plastic tweezers and fuse alloca-
tion diagram are located in the compartment for
the onboard tool kit, refer to page182.

an engine or body ground of the assisting
vehicle.
5.Attach the second end of the cable to the
negative terminal of the battery or to the
engine or body ground of the vehicle to be
started.
Starting engine
1.Start the engine on the assisting vehicle
and allow it to run for several minutes at
increased speed.
2.Start the engine on the other vehicle in the
usual way. If the first start attempt is not
successful, wait a few minutes before
another attempt in order to allow the dis-
charged battery to recharge.
3.Let the engines run for a few minutes.
4.Disconnect the jumper cables by reversing
the connection sequence.
Check the battery and recharge if necessary.
Never use spray fluids to start the
engine.<
Towing and tow-starting
Always observe all applicable towing laws
and regulations.<
Never allow passengers to ride in a towed
vehicle for any reason.<
Using tow fitting
The threaded tow fitting is stored in the
onboard tool kit and must always remain in the
vehicle. It can be screwed in at the front or rear
of the BMW.In order to avoid damaging the tow fitting
and the vehicle, please follow these
instructions: use only the tow fitting provided
with the vehicle and screw it all the way in. Use
the tow fitting for towing only on roads. Avoid
lateral loading of the tow fitting, e.g. do not lift
the vehicle by the tow fitting.<
Access to screw thread
Rectangular cover panel in bumper: press on
the arrow symbol on the cover panel.

Rear
Being towed
Make sure that the ignition key is in posi-
tion 1, as otherwise the steering lock will
engage, making it impossible to steer the vehi-
cle. There is no power assist with the engine
stopped. This then requires increased effort for
braking and steering. Active steering is deacti-
vated and larger steering wheel movements are
required.<
Switch on the hazard warning flashers depend-
ing on the local regulations. If the electrical sys-
tem fails, mark the vehicle to be towed, e.g. with
a sign or warning triangle in the rear window.
