service reset VOLVO S40 2008 Owners Manual

If the vehicle has been involved in a collision, the text CRASH MODE SEE MANUAL may appear in the information
display. This indicates that the vehicle's functionality has been reduced.
NOTE
This text can only be shown if the display is undamaged and the vehicle's electrical system is intact.
CRASH MODE is a feature that is triggered if one or more of the safety systems (for example, front or side airbags,
an inflatable curtain, or one or more of the seat belt pretensioners) has deployed. The collision may have damaged an
important function in the vehicle, such as the fuel lines, sensors for one of the safety systems, the brake system, etc.
WARNING
Never attempt to repair the vehicle yourself or to reset the electrical system after the vehicle has displayed
CRASH MODE SEE MANUAL. This could result in injury or improper system function.
Restoring the vehicle to normal operating mode should only be done by a trained and qualified Volvo service
technician.
After CRASH MODE SEE MANUAL has been displayed, if you detect the odor of fuel vapor, or see any signs of
fuel leakage, do not attempt to start the vehicle. Leave the vehicle immediately.
Attempting to start the vehicle
If damage to the vehicle is minor and there is no fuel leakage, you may attempt to start the vehicle. To do so:
1. Remove the ignition key or optional keyless drive start control (see page 138
).
2. Reinsert the key or start control in the ignition switch. The vehicle will then attempt to reset CRASH MODE to
normal mode.
3. Try to start the vehicle.
Moving the vehicle
If the electrical system is able to reset system status to normal (CRASH MODE SEE MANUAL will no longer be
displayed), the vehicle may be moved carefully from its present position, if for example, it is blocking traffic. It
should, however, not be moved farther than is absolutely necessary.
WARNING
Even if the vehicle appears to be drivable after CRASH MODE has been set, it should not be driven or towed
(pulled by another vehicle). There may be concealed damage that could make it difficult or impossible to control.
The vehicle should be transported on a flatbed tow truck to a trained and qualified Volvo service technician for
