Start/Stop Function - Volvo XC40 Owner's Manual

Start/Stop function

With the Start/Stop function, the engine
switches off temporarily when the car has stop-
ped e.g. at traffic lights or in a traffic queue, and
then starts again automatically when the journey
is resumed.
The start/stop function reduces fuel consump-
tion, which in turn contributes to reduced exhaust
emissions.
The system makes it possible to adopt an envi-
ronmentally-conscious driving style by allowing
the car to engine auto-stop when possible.

Driving with start/stop function
The Start/Stop function temporarily switches off
the engine when stationary and then restarts it
automatically when the journey is resumed.
The Start/Stop function is available when the
engine is started and can be activated if certain
conditions have been met. The driver display indi-
cates whether the function is available, active or
not available.
All of the car's normal systems such as lighting,
radio, etc. work normally, even when the engine is
auto-stopped. However, some equipment may
have its output temporarily reduced, e.g. the cli-
mate control system's fan speed or extremely
high volume on the audio system.
Auto-stop
The following is required for the engine to auto-
stop:
•
Stop the car with the foot brake and then
keep your foot on the brake pedal - the
engine stops automatically.
4
In drive mode Eco or Comfort , the engine may
auto-stop before the car is completely stationary.
With adaptive cruise control or Pilot Assist acti-
vated, the engine will auto-stop after approxi-
mately three seconds.
STARTING AND DRIVING
Autostart
The following is required for the engine to auto-
start:
•
Release the brake pedal - the engine will
autostart and you can continue driving. On an
uphill gradient hill start assist (HSA)
engages, which prevents the car from rolling
backwards.
•
When the Auto Hold function is activated,
auto-start is delayed until the accelerator
pedal is depressed.
•
When adaptive cruise control or Pilot Assist
is activated, the engine will auto-start when
the accelerator pedal is depressed, or by
pressing the button on the left keypad
of the steering wheel.
•
Maintain foot pressure on the brake pedal
and depress the accelerator pedal - the
engine auto-starts.
•
On a downhill gradient: Release pressure on
the brake pedal slightly so that the car
begins to roll - the engine will auto-start after
a slight speed increase.
