Volvo XC90: Starting and driving / Driving with the Start/Stop function

Start/stop is a function that temporarily turns off the engine when the vehicle is stationary and then automatically starts it when needed. The Start/Stop function is available when the ignition is started and can be activated if certain conditions are met.

The instrument panel indicates when the function is

• Available
• active
• not available.

All of the vehicle's ordinary systems, such as lighting, radio, etc. function normally when the engine has been auto-stopped. Certain functions may be temporarily reduced however such as the climate system's blower speed or extremely high audio system volume.

Auto-stop

To auto-stop the engine:

• Stop the vehicle by applying the brakes and keep the brake pedal depressed. The engine will auto-stop.

In Comfort or Eco drive mode, the engine may auto-stop before the vehicle has com- pletely stopped.

With Adaptive Cruise Control or Pilot Assist activated, the engine will auto-stop about three seconds after the vehicle has stopped.

Auto-start

The following conditions must be met for the engine to auto-start.

• Release the brake pedal. The engine will auto-start and the vehicle can be driven. On an uphill gradient, Hill Start Assist (HSA¹ ) will activate to help prevent the vehicle from rolling backward.
• When the Auto-hold function is activated, auto-start will be delayed until the accelerator is pressed.
• When Adaptive Cruise Control or Pilot Assist are activated, the engine will autostart when the accelerator pedal is depressed or the button on the leftside steering wheel keypad is pressed.
• Maintain pressure on the brake pedal and press the accelerator pedal. The engine will auto-start.
• On a downhill gradient: Release the brake pedal slightly so that the vehicle begins to roll. The engine will auto-start after a slight increase in speed.
