First, check that no fuel is leaking from the car. There must be no smell of fuel either.
If everything seems normal and you have checked for indications of fuel leakage, you may attempt to start the car.
Remove the remote control key and open the driver's door. If a message is now shown to the effect that the ignition is on, press the start button. Then close the door and reinsert the remote control key. The car's electronics will now try to reset themselves to normal mode. Then try to start the car.
If the message Safety mode See manual is still shown on the display then the car must not be driven or towed but a vehicle recovery service used instead. Even if the car appears to be driveable, hidden damage may make the car impossible to control once moving.
Never, under any circumstances, attempt to restart the car if it smells of fuel when the Safety mode See manual message is displayed. Leave the car at once.
If the car is in safety mode it must not be towed. It must be transported from its location. Volvo recommends that it is transported to an authorised Volvo workshop.
