If you need to shorten the belt, pull on the loose end of the webbing until the belt fits snugly. To unfasten the belt, push the release button on the buckle. This allows the tongue to unlatch from the buckle. Safety Belt Extension Assembly Unfastening the center rear lap safety belt NOTE: Be sure to read and understand Important Safety Belt Information in this chapter. Pull the belt across your hips and insert the tongue into the correct buckle on your seat until you hear a snap and feel it lock. Make sure the buckle is securely fastened. If you need to lengthen the belt, unfasten it and tip the belt tongue at a right angle to the belt. Pull the belt tongue over your lap until it reaches the buckle. For some people, the safety belt may be too short even when it is fully extended. You can add about eight inches (20 cm) to the belt length with a safety belt extension assembly (part number 611C22). Safety belt extensions are available at no cost from your dealer. Use only extensions manufactured by the same supplier as the safety belt. Manufacturer identification is located at the end of the webbing on the label. Also, use the safety belt extension only if the safety belt is too short for you when fully extended. Do not use extension to change the fit of the shoulder belt across the torso. 144
