Overrun Cut-Off; Stop-Start System - Opel Vivaro C 2023 Manual

156 Driving and operating
Starting the vehicle at low
temperatures
Starting the engine without additional
heaters is possible down to -25 °С for
diesel engines and -30 °C for petrol
engines. Required is an engine oil
with the correct viscosity, the correct
fuel, performed services and a
sufficiently charged vehicle battery.
With temperatures below -30 °C the
automatic transmission requires a
warming phase of approx.
five minutes. The selector lever must
be in position P.
Turbo engine warm-up
Upon start-up, engine available
torque may be limited for a short time,
especially when the engine
temperature is cold. The limitation is
to allow the lubrication system to fully
protect the engine.

Overrun cut-off

The fuel supply is automatically cut off
during overrun, i.e. when the vehicle
is driven with a gear engaged but
accelerator pedal is released.
Depending on driving conditions, the
overrun cut-off may be deactivated.

Stop-start system

The stop-start system helps to save
fuel and to reduce the exhaust
emissions. When conditions allow, it
switches off the engine as soon as the
vehicle is at a low speed or at a
standstill, e.g. at a traffic light or in a
traffic jam.
Activation
The stop-start system is available as
soon as the engine is started, the
vehicle starts-off and the conditions
as stated below in this section are
fulfilled.
The system can be activated in the
vehicle personalisation 3 109. If the
stop-start system is temporarily not
available, the control indicator D
flashes for a few seconds.
Deactivation
The stop-start system can be
deactivated in the vehicle
personalisation 3 109.
If the system is deactivated during an
Autostop, the engine restarts
immediately.

An Autostop can be activated at a
