Automatic transmission
If a sporty driving program is selected on a Vectra with an automatic transmission, the corresponding control lamp lights up in the instrument panel. Contact with the mass of the bulb is provided by the automatic transmission control unit. If the light does not come on during the sport driving program, replace it.
On the contrary, if the control lamp in the indicator display lights up while driving, then there is a defect in the system. Go to the workshop and check there.
