Seat belt adjustment
The seat-belt adjustment function adjusts the driver's and front-passenger seat belt to the upper body of the occupants.
The belt strap is tightened slightly when:
• you engage the belt tongue in the belt buckle and you then turn the SmartKey to position 2 in the ignition lock.
• the SmartKey is in position 2 in the ignition lock and you then engage the belt tongue in the buckle.
The seat-belt adjustment will apply a retraction force if any slack is detected between the occupant and the seat belt. Do not hold on to the seat belt tightly while it is adjusting. You can switch the seat-belt adjustment on and off in the on-board computer.
The seat-belt adjustment is an integral part of the PRE-SAFE® convenience function. More information about PRE-SAFE® can be found in the "PRE-SAFE® (preventative occupant protection)" section.
