Driving

Upshifts and downshifts are executed only
when they will result in a plausible combination
of engine and vehicle speed; thus, for example,
a downshift that would cause the engine to
overrev will not be executed by the system.
The gear selected is briefly displayed in the
instrument cluster, followed again by the gear
actually in use.

on, the brake is depressed and the button on
the selector lever is pressed, the selector lever
lock can be overridden:

7-gear Sport automatic

transmission with double

clutch

The concept

The 7-gear Sport automatic transmission with
double clutch is an automated manual trans-
mission with two clutches and secondary gear

sets in which the clutching and shifting is han-
dled by an electrohydraulic system.
With the 7-gear Sport automatic transmission
with double clutch, the gears are shifted without
an interruption in driving power.
You operate the 7-gear Sport automatic trans-
mission with double clutch using the selector
lever and two shift paddles on the steering
wheel.
It offers you the following functions:

Either manual or automatic mode: sequen-
tial mode or drive mode

Automatic downshifting and protection
against incorrect gear selection, even in
sequential mode

Acceleration assistant, Launch Control,
refer to page

Automatic intermediate throttle application

System limitations

The 7-gear Sport automatic transmission with
double clutch has an overheating protection
that protects the clutch from extreme loads.

The indicator lamp lights up in yellow if
the transmission becomes too warm.
Avoid high engine loads and frequent

accelerations from zero. If the transmission is
overheated, the indicator lamp lights up in red
and the power flow to the motor is interrupted. It
is only possible to continue driving once the
transmission has cooled down.
Avoid frequent powerful accelerations from
zero and do not hold the vehicle on inclines by
pressing lightly on the accelerator while letting
the clutch slip, as this may cause the transmis-
sion to overheat.
