BMW Z4 sDrive35is 2011 - Manual (Page 58)

7-gear sport automatic
transmission with dual
clutch*
The concept
This transmission is an automated manual
transmission with two clutches and two gearbox
components in which the gears are changed
without loss of torque.
The transmission is operated using the selector
lever and two shift paddles on the steering
wheel.
Functions:
▷ Choice of manual or automatic operation:
manual mode or drive mode.
▷ Automatic downshifting and protection
against selecting the wrong gear, even in
manual mode.
▷ Acceleration assistant, Launch Control, re‐
fer to page 60 .
▷ Automatic throttle blip.
System limits
This transmission is equipped with an overheat‐
ing protection system that protects the clutches
against extremely high loads.
The indicator lamp lights up yellow if
the transmission becomes too warm.
Avoid high engine loads and driving off
frequently.
If the transmission overheats, the indicator lamp
lights up red and power flow to the engine is in‐
terrupted. You can only continue driving after
the transmission has cooled down.
Avoid driving off frequently with high accelera‐
tion and do not hold the vehicle on inclines by
depressing the accelerator lightly; otherwise,
the transmission may overheat.
