SUBJECT:
Mechanical front seats, adjusting seat slide rail locking position.
DESCRIPTION:
This TNN describes the method for proper front seat slide rail adjustment after replacing or removing a seat from the vehicle. If this is not properly done, front seat movement under acceleration or deceleration might be experienced.
CHECKING PARALLELISM:
Verify that each adjustment mechanism can be locked individually to ensure that there is no problem with the slide rail lock mechanism (due to damage or foreign objects).
Sit on the seat. Lock one side and move the other side of the seat forward and rearward to determine if the seat adjustment mechanism must be moved forward or rearward in relation to the slide rails.
ADJUSTING THE SLIDE RAILS:
Step 1:
Remove the four cover panels for the slide rail bolts.
Unscrew front and rear slide rail bolts a couple of turns but do not remove them.
Step 2
Check if both adjustment mechanisms can lock at the same time in each slide rail now that the slide rail bolts are loosened.
If both slide rails can be locked at the same time, tighten all bolts to 29.50 Lb ft (40 Nm).
Start with the front bolts, then rear bolts and proceed with step 4.
If the slide rails cannot be aligned, proceed with step 3.
Step 3:
Press one slide rail forward/rearward based on the result of step 1. While doing so, tighten the front bolt. Then tighten the rear bolt of the same rail. Make sure that the slide rail is locked when this is done.
Next, check that both sides can lock at the same time by sitting on the seat and adjusting its longitudinal position. With both slide rail mechanisms locked, tighten the two remaining loose bolts (front and rear). Check that the longitudinal position and height of the seat can be adjusted.
If the function is still not OK, start adjusting the other rail according the method described above and work in the opposite direction. Finally, tighten all four bolts to 29.50 Lb ft (40 Nm). Reinstall the cover panels.
Step 4:
Check the longitudinal and height position of the seat. If you can still feel play and hear a clicking sound see Service Bulletin 850036 for reducing the play/clicking sound at the lower mounting points of the front height adjuster.
