4.2.6.￿Service￿information
For￿work￿required￿on￿the￿oil￿circuit￿of￿the￿automatic￿transmission,￿for￿example￿after￿an￿accident,￿or￿if
the￿oil￿circuit￿has￿to￿be￿opened￿owing￿to￿a￿repair,￿there￿must￿be￿maximum￿cleanliness.￿They￿include:
• Optimal￿cleaning￿of￿the￿outer￿oil￿circuit￿areas￿before￿disassembly￿of￿the￿components￿or
opening￿the￿oil￿circuit.
• Immediate￿closure￿of￿openings￿and￿lines￿after￿disassembly￿without￿delay￿and￿using￿clean
original￿plugs.￿Do￿not￿use￿unsealed￿components￿or￿replacement￿parts￿of￿the￿oil￿circuit￿without
checking￿for￿cleanliness￿and￿where￿possible￿competent￿repair.
• The￿work￿bay￿in￿which￿an￿automatic￿transmission￿is￿opened￿up￿must￿be￿absolutely￿clean￿and
protected￿from￿dirt￿contamination,￿including￿during￿work￿interruptions,￿e.g.￿by￿means￿of￿an
adequate,￿clean￿and￿lint-free￿cover.
Lifetime￿oil￿filling
At￿present,￿as￿is￿the￿case￿with￿the￿F85/F86￿and￿F90￿with￿automatic￿transmission,￿a￿transmission￿oil
change￿at￿2000 km￿(1200￿mile￿running-in￿check)￿and￿at￿every￿3rd￿engine￿oil￿change￿is￿not￿required￿for
the￿F96/F97￿with￿M￿automatic￿transmission.
4.3.￿M￿xDrive
"High-performance￿dynamic￿handling￿on￿the￿one￿hand￿and￿the￿everyday￿usability￿of￿an￿SUV/SAV
on￿the￿other"￿is￿how￿we￿could￿summarize￿the￿typical￿M￿concept￿approach￿in￿which￿the￿individual
drivetrain￿components￿are￿perfectly￿matched￿with￿the￿M￿xDrive￿system.￿That￿enables￿the￿new￿BMW
X3￿M￿and￿BMW￿X4￿M￿to￿have￿the￿same￿familiar￿precise￿sports￿handling￿whether￿being￿driven￿on￿the
race￿track￿or￿the￿public￿road.￿In￿addition,￿they￿are￿also￿a￿delight￿to￿drive￿even￿in￿unpleasant￿weather
conditions￿such￿as￿rain￿and￿snow￿or￿off￿road￿thanks￿to￿noticeable￿extra￿traction￿and￿controllability
right￿up￿to￿the￿limits￿of￿handling￿stability.￿The￿agile￿rear-oriented￿design￿is￿achieved￿by￿allowing￿the￿M
xDrive￿to￿bring￿the￿front￿axle￿to￿bear￿only￿when￿the￿rear￿wheels￿have￿reached￿their￿limits￿and￿additional
traction￿force￿is￿required.￿Even￿when￿adopting￿a￿very￿vigorous￿driving￿style￿using￿a￿lot￿of￿power,￿the
new￿BMW￿X3￿M￿and￿BMW￿X4￿M￿with￿M￿xDrive￿show￿themselves￿to￿be￿predictable￿and￿effortless￿to
control￿for￿the￿driver,￿so￿that￿the￿outstanding￿performance￿of￿the￿vehicles￿can￿be￿experienced￿even
more￿intensely.

With￿your￿free￿hand,￿press￿the￿selector￿lever￿into￿selector￿lever￿position￿N￿and
keep￿it￿there￿until￿selector￿lever￿position￿N￿appears￿in￿the￿instrument￿cluster.
A￿CC￿message￿is￿displayed￿in￿the￿KOMBI￿and￿in￿the￿CID.
Release￿the￿start/stop￿button￿and￿the￿selector￿lever.
Release￿the￿brake￿as￿soon￿as￿the￿starter￿motor￿stops.
