STARTING AND DRIVING -> Start/stop function for Your Volvo XC40 SUV Second Generation (2022-2026)

STARTING AND DRIVING  
|| engine whose speed is reduced to idling  
the road's downhill gradient is steeper  
than approx. 6%  
Cruise control Eco Cruise  
speed with reduced consumption.  
When using the cruise control in the Eco drive  
mode, the car's acceleration and deceleration  
will be lower compared to other drive modes,  
which enables further fuel savings. This means  
that the car's speed can be slightly above or  
below the set speed.  
Manual gear changing is performed with  
the steering wheel paddles*.  
The function is best used where it is possible  
to freewheel a long way e.g. roads with a  
slight downhill gradient or when there is a pre-  
dictable speed reduction to freewheel into a  
zone with a lower speed limit.  
Deactivating and switching off the  
freewheel function  
In certain situations it may be desirable to  
deactivate or switch off the function in order  
to use engine braking. Examples of such situa-  
tions may be on steep downhill gradients or  
before an imminent overtaking manoeuvre - in  
order to be able to do it in the safest way pos-  
sible.  
On a smooth road, the car's speed can  
deviate from the set speed when the  
cruise control is active and the car free-  
rolls.  
Activating the freewheel function  
The function is activated when the accelerator  
pedal is fully released, in combination with the  
following parameters:  
On a steep uphill slope, the car's speed  
drops until a downshift is made13, then  
reduced acceleration starts in order to  
achieve the set speed.  
Drive mode Eco is activated.  
The gear selector is in D position.  
Deactivate the freewheel function as follows  
Speed within the range of  
actuate the accelerator or brake pedal  
approx. 65-140 km/h (40-87 mph).  
On a downhill slope where the car free-  
rolls, the car's speed can be slightly above  
or below the set speed. The function uses  
normal engine braking to maintain the set  
speed. The foot brake is also used if nec-  
essary.

Even without the freewheel function, it is pos-  
sible to freewheel for short distances. This, in  
turn, reduces consumption. However, for the  
best fuel economy it is better to have the free-  
wheel function activated and be able to free-  
wheel for longer distances.

STARTING AND DRIVING  
Eco gauge in the driver display  
Activating and deactivating drive  
mode Eco with the function button  
There is a function button for Eco drive mode  
in the centre display's function view unless  
the car was equipped with a drive mode but-  
ton in the centre console.  
The Eco mode is deactivated when the engine  
is switched off, and it must therefore be acti-  
vated after each time the engine is started.  
The driver display shows ECO when the func-  
tion is activated.  
NOTE  
When the Eco drive mode is activated,  
several parameters in the climate control  
system's settings are changed, and several  
electricity consumer functions are reduced.  
Certain settings can be reset manually, but  
full functionality is only regained by switch-  
ing off Eco drive mode or adapting  
Individual* drive mode with full climate  
functionality.  
Selecting Eco drive mode in the centre  
display function view  
In the event of difficulties due to misting,  
press the button for max. defroster which has  
normal functionality.  
The ECO gauge indicates how fuel-efficient  
the driving is:  
Press the Driving Mode ECO button to  
activate or deactivate the function.

With fuel-efficient driving, the gauge  
shows a low value with the pointer in the  
green zone.

Start/stop function  
Driving with start/stop function  
With the start/stop function, the engine  
switches off temporarily when the car has  
stopped e.g. at traffic lights or in a traffic  
queue, and then starts again when it is nee-  
ded.  
The start/stop function reduces fuel consump-  
tion, which in turn contributes to reduced  
exhaust emissions.  
The start/stop function temporarily switches  
off the engine when stationary and then  
starts it automatically when required.  
The Start/Stop function is available when the  
car is started and can be activated if certain  
conditions have been met.  
Declutch, set the gear lever in neutral  
position and release the clutch pedal - the  
engine stops automatically.  
In drive mode Comfort or Eco, the engine  
may auto-stop before the car is completely  
stationary.  
The driver display indicates when the function  
is  
With adaptive cruise control or Pilot Assist  
activated, the engine auto-stops approxi-  
mately 3 seconds after the car has stopped.  
The system makes it possible to adopt an  
environmentally-conscious driving style by  
allowing the car to engine auto-stop when  
possible.

engine is auto-stopped. However some equip-  
ment may have its output temporarily reduced  
e.g. the climate control system's fan speed or  
extremely high volume on the audio system.
