2023 Volvo XC60 / XC60 Recharge Plug-in Hybrid Start/stop function
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 needed. The start/stop function reduces fuel consumption, which in turn can contribute to an environmentally conscious driving style and reduced emissions.
Points to remember when using the start/stop function
For the start/stop function to work requires that a number of conditions are met.
The start/stop function is not activated
One or more criteria may mean that the engine is not switched off/the function is not activated.
- the driver has not fastened the seatbelt
- the car has not been able to reach a speed of approx. 10 km/h (6 mph) after starting or the function has been activated a number of times successively
- the engine has not reached normal operating temperature
- the windscreen’s electric heating is activated
- the environment in the passenger compartment deviates from the set values
- the driver is making large steering wheel movements
- the road is very steep
- the bonnet is opened
- the ABS system has been activated
- in the event of heavy braking (even without the ABS system having been activated)
- the capacity of the starter battery has fallen below the minimum permissible level
- many starts during a short period of time have activated the starter motor’s thermal protection
- the exhaust system’s particulate filter is full
- a trailer is connected to the car’s electrical system.
High current take-off may lead to battery capacity falling below the lowest permitted level, which temporarily limits the start/stop function. The engine then starts automatically without the driver lifting his/her foot from the brake pedal.
The start/stop function is not deactivated
One or more criteria may mean that the engine is not started/the function is not deactivated.
- the driver has not fastened the seatbelt
- gear position P is engaged and the driver door is open.
The start/stop function is deactivated without the brake pedal being released
In the following cases, the function may be deactivated and the engine started without the driver releasing the brake pedal:
- high humidity in the passenger compartment forms misting on the windows
- the environment in the passenger compartment deviates from the set values
- repeated pumping of the brake pedal
- the bonnet is opened
- the capacity of the starter battery has fallen below the minimum permissible level
- the driver’s seatbelt is unbuckled and the gear selector is in position D or N
- the gear selector is moved from position D to position R or M
- the driver door is opened with the gear selector in position D.
Do not open the bonnet when the start/stop function is active. Switch off the engine normally before raising the bonnet.
Activating and deactivating the start/stop function
Activating the start/stop function
Depress and hold the brake pedal depressed. The start/stop function is activated and the engine is switched off.
Note
- In some cases, the start/stop function is activated before the car is completely stationary.
- When adaptive cruise control or Pilot Assist is activated, the start/stop function is activated for a few seconds after the car is completely stationary.
All of the car’s normal systems, such as lighting and radio, work normally even when the start/stop function is activated. However, some equipment may have temporarily reduced function, such as the climate control’s fan speed or loudspeaker volume.
Deactivating the start/stop function
Release the brake pedal or gently depress the accelerator pedal.The start/stop function is deactivated and the engine starts.
When the start/stop function is deactivated and:
- the function for automatic braking when stationary (Auto hold) is activated, start of the engine is delayed until the accelerator pedal is depressed
- adaptive cruise control or Pilot Assist is activated, the engine starts when the accelerator pedal is depressed or by pressing the
button on the left-hand steering wheel keypad - the car is facing uphill, hill start assist (HSA (Hill Start Assist)) engages to prevent the car from rolling backwards
- the car is facing downhill, release the brake pedal slightly. A small increase in speed starts the engine.
