Notes

Maintenance and repair

Advanced technology, e.g. the
use of modern materials and high-
performance electronics, requires spe-
cially adapted maintenance and repair
methods. Therefore, only have corre-
sponding work on your BMW carried
out by a BMW center or a workshop
that works according to BMW repair
procedures with correspondingly
trained personnel. If work is carried out
improperly there is a danger of conse-
quential damage and the related safety
risks.

Parts and accessories

Important safety information!
For your own safety, use genuine
parts and accessories approved by
BMW.
When you purchase accessories tested
and approved by BMW and Original
BMW Parts, you simultaneously acquire
the assurance that they have been thor-
oughly tested by BMW to ensure opti-
mum performance when installed on
your vehicle.
BMW warrants these parts to be free
from defects in material and workman-
ship.
BMW will not accept any liability for
damage resulting from installation of
parts and accessories not approved by
BMW.
BMW cannot test every product on the
market to determine whether it can be
used on a BMW safely and without risk
to either the vehicle, its operation, or its
occupants.
Original BMW Parts, BMW Accessories
and other products approved by BMW,
together with professional advice on
using these items, are available from all
BMW 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 portable cellular phone
from within the vehicle without using an
externally mounted antenna – or trans-
ceiver equipment, such as a CB,
walkie-talkie, ham radio or similar
accessories, may cause extensive dam-
age to the vehicle, compromise its
safety, interfere with the vehicle's elec-
trical system or affect the validity of the
BMW Limited Warranty. Contact your
BMW center for additional information.
Do not use key or remote control to
lock doors or luggage compartment
with anyone inside the vehicle. Refer to
the Owner's Manual for more details.

If the engine does not start on the first
attempt – if it is very hot or cold, for
instance:
>Press the accelerator pedal halfway
down while engaging the starter.
Cold starts at extremely low tempera-
tures below approx. +57/–156 and at
altitudes over 3,300 ft/1,000 m:
>On the first start attempt, it may be
necessary to engage the starter for a
longer period – but no longer than
20 seconds
>Press the accelerator pedal halfway
down while engaging the starter.
Extended starting attempts, char-
acterized by excessively frequent
or long periods with the starter
engaged can damage the catalytic con-
verter.<
Engine idle speed is controlled by the
engine computer system. Increased
speeds at start-up are normal and
should decrease as the engine warms
up. If engine speed does not decrease,
service is required.
To prevent the battery from discharg-
ing, always deactivate electrical
devices that are not in use. Switch the
ignition off when the vehicle is not
