F97/F98￿Complete￿Vehicle
4.￿Powertrain
Manual￿mode/sequential￿mode
The￿gears￿can￿be￿shifted￿manually￿at￿the￿appropriate￿road￿speed￿and￿engine￿revs￿by￿means￿of￿"+"
and￿"–"￿gearshift￿paddles￿on￿the￿steering￿wheel￿or￿by￿moving￿the￿gear￿selector￿lever￿"forward"￿or
"back".￿The￿selected￿gear￿is￿maintained￿even￿when￿the￿engine￿speed￿limitation￿is￿reached,￿but￿an
automatic￿downshift￿is￿performed￿when￿the￿vehicle￿drops￿below￿the￿gear-specific￿minimum￿driving
speed.
When￿manual￿mode￿is￿selected￿for￿the￿first￿time￿after￿a￿change￿of￿terminal￿status￿(engine￿restart),￿the
last￿Drivelogic￿level￿used￿is￿active.
Three￿driving￿programs￿are￿also￿available￿here￿for￿selection:
1:￿Comfortable,￿smooth￿gearshifts￿in￿all￿driving￿conditions
2:￿Sporty,￿fast￿gearshifts,￿light￿gearshift￿jolts￿permitted￿at￿higher￿engine￿loads￿and￿speeds
3:￿Maximum￿sporty￿shift￿speed￿and￿gearshifts￿are￿the￿requirement￿for￿the￿activation￿of￿Launch￿Control.
Using￿the￿highest￿program,￿i.e.￿3,￿does￿not￿require￿the￿M￿DSC￿to￿be￿deactivated.
4.2.4.￿Launch￿Control
During￿the￿first￿5000￿km￿(3100￿miles)￿run-in￿distance,￿the￿Launch￿Control￿must￿not￿be￿used.
The￿Launch￿Control￿is￿released￿at￿the￿factory.￿Release￿of￿the￿Launch￿Control￿is￿no￿longer￿restricted￿to
the￿2000￿km￿(1200￿miles)running-in￿check.
Premature￿wear￿occurs￿as￿a￿result￿of￿the￿high￿load￿on￿the￿vehicle￿components￿when￿using￿Launch
Control.
Launch￿Control
Function:￿Launch￿Control￿enables￿optimal￿acceleration￿when￿driving￿off￿on￿a￿non-skid￿roadway.

Precondition/Action
The￿vehicle￿must￿be￿stationary,￿the￿engine￿running￿and￿at￿operating
temperature￿(approx.￿10 km￿(6￿mph)￿warm-up￿journey).
The￿M￿Dynamic￿Stability￿Control￿(M￿DSC)￿is￿deactivated.￿(4WD)
The￿manual￿mode￿and￿the￿third￿Drivelogic￿driving￿program￿are￿selected.
The￿brake￿pedal￿is￿gently￿pressed￿with￿the￿left￿foot￿and￿held.
The￿accelerator￿pedal￿is￿depressed￿fully￿and￿held￿in￿this￿position.
In￿the￿M￿instrument￿cluster￿a￿flag￿symbol￿must￿appear￿(if￿not,￿check￿notes￿and
steps￿1-5).
An￿optimum￿engine￿speed￿for￿pulling￿away￿is￿adjusted.
The￿left￿foot￿is￿taken￿off￿the￿brake￿within￿5￿seconds.
