Driver And Front Passenger Backrest Adjustment Motor -V45- / -V46-, Removing And Installing, Standard Seat, China Version: Installing

WARNING:

Repairing pyrotechnic components (for example the airbag and seat belt tensioner) incorrectly increases the risk of unintentional deployments when the battery is connected.

Equipped on Some Models: 

-- Check the left and right position of the backrest frame and hinge.

-- If necessary, correct the position accordingly.

Continued for all Versions: 

-- Check if the profiles of the adjustment shaft and the mount in the backrest adjustment motor are congruent to each other.

-- If the position varies, connect an external 12-volt power source to the backrest adjustment motor and turn the mount until the profiles of the adjustment shaft and mount are congruent.

-- Push the adjustment shaft -3- through the mount in the backrest adjustment motor -2- and only tighten the bolt -arrow- for the backrest adjustment motor hand-tight.
