Parts and accessories
For your own safety, use genuine parts
and accessories approved by BMW.
When you purchase accessories tested and
approved by BMW and Genuine BMW Parts,
you simultaneously acquire the assurance that
they have been thoroughly tested by BMW to
ensure optimum performance when installed
on your vehicle.
BMW warrants these parts to be free from
defects in material and workmanship.
BMW will not accept any liability for damage
resulting from installation of parts and accesso-
ries not approved by BMW.
BMW cannot test every product made by other
manufacturers to verify if it can be used on a
BMW safely and without risk to either the vehi-
cle, its operation or its occupants.
Genuine BMW Parts, BMW Accessories and
other products approved by BMW, together
with professional advice on using these items,
are available from all BMW Sports Activity Vehi-
cle Centers.
Installation and operation of non-BMW
approved accessories such as alarms, radios,
amplifiers, radar detectors, wheels, suspension
components, brake dust shields, telephones,
including operation of any mobile phone from
within the vehicle without using an externally
mounted antenna, or transceiver equipment
such as CBs, walkie-talkies, ham radios or sim-
ilar accessories, may cause extensive damage
to the vehicle, compromise its safety, interfere
with the vehicle's electrical system or affect the
validity of the BMW Limited Warranty. Refer to
your BMW Sports Activity Vehicle Center for
additional information.<
Maintenance, replacement, or repair of
the emission control devices and sys-
tems may be performed by any automotive
repair establishment or individual using any cer-
tified automotive part.<
California Proposition 65 Warning
California laws require us to issue the following
warning:
Engine exhaust and a wide variety of
automobile components and parts,
including components found in the interior fur-
nishings in a vehicle, contain or emit chemicals
known to the State of California to cause cancer
and birth defects and reproductive harm. In
addition, certain fluids contained in vehicles and
certain products of component wear contain or
emit chemicals known to the State of California
to cause cancer and birth defects or other
reproductive harm.
Battery posts, terminals and related accesso-
ries contain lead and lead compounds. Wash
your hands after handling.
Used engine oil contains chemicals that have
caused cancer in laboratory animals. Always
protect your skin by washing thoroughly with
soap and water.<

3.Check and correct the tire inflation pressure
at the earliest opportunity.
Protect valve stems with valve screw
caps against dirt and contamination.
Dirt in valve stems is a frequent source of
gradual air loss.<
4.Initialize the Flat Tire Monitor, refer to
page92, or reset the Tire Pressure Monitor,
refer to page94.
5.Replace the damaged 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.
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. Restore the wheels and tires to
their original size as quickly as possible. Failure
to do so is a safety risk.<
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 Sports Activity Vehicle 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. Connections, refer to
Jump starting on page256.
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 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:
>Seat, mirror and steering wheel memory
The positions must be stored again, refer to
page44.
>Time and Date
The values must be updated, refer to
pages81, 82.
>Radio
Stations must be stored again if necessary,
refer to page168.
>Navigation system
Wait until the system starts, refer to
page159.
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, a pair of plastic tweezers and infor-
mation on the fuse assignment are located near
the fuses in the cargo bay.
