I have a 2001 gls that I took in get aligned when I got new tires. The mechanic doing the alignment showed me the options on his specifying program that had different groups with different load possibilities in each group. Each of these offered different specs to align to. I had no idea what this was (neither did the mechanic or the dealer we called) - so no alignment was done. I think it is listed on the paper on the underside of the dash - the group number being listed after an L or K.
I have searched here and other places but have found nothing. I would rather not give the dealer the $200 they want to align it, but without knowing more I may have to.
Anyone have any info?
