without the brake pedal depressed. To avoid unwanted vehicle
movement, always set the parking brake.

If it is necessary to use the above procedure to move the gearshift lever,
it is possible that a fuse has blown or the vehicle’s brakelamps are not
operating properly. Refer toFuses and relaysin theRoadside
