Operation Manual

126 Driving and operating
Activation
In automatic mode, press button
s; control indicator s
illuminates in the instrument cluster
3 86.
The settings of certain electronic
systems are adapted to reduce fuel
consumption:
■ The engine reacts less quickly to
the accelerator pedal.
■ Automatic upshift points occur
sooner and downshift points occur
later.
■ The transmission locks itself to the
engine at cruising speeds, to
improve efficiency and increase
power and torque.
■ The fuel supply is automatically cut-
off more quickly during vehicle
deceleration. Overrun cut-off
3 121.
Do not use fuel economy mode whilst
towing, e.g. a trailer.
Deactivation
Fuel economy mode is switched off
by pressing button s again;
control indicator s extinguishes in
the instrument cluster.
Fault
In the event of a fault in the automatic
transmission, control indicator Z
illuminates in the instrument cluster
3 81. Automatic shifting may be much
harsher than normal or, in the case of
a serious fault, cancelled altogether.
Have the cause of the fault remedied
by a workshop.
If control indicator g illuminates in
the instrument cluster when the
engine is running, this may indicate
a fault in the transmission electronics
3 82. The electronics switch to the
emergency running programme, fuel
consumption may increase and the
driveability of the vehicle may be
affected. Seek the assistance of
a workshop.
Interruption of power
supply
The clutch is not disengaged if the
vehicle battery is discharged and
a gear has been selected. The vehicle
cannot move. The selector lever
cannot be moved out of position P or
N.
If the battery is discharged, start the
vehicle using jump leads 3 179.
If the battery is not the cause of the
fault, release the selector lever:
1. Switch off ignition and remove the
key.
2. Depress and hold foot brake.
