looking for info on the + - buttons on shifter no book with car anybody know what they do? :screwy:

You can get a PDF version of your owners manual on the GM website

Electronic Range Select Mode
This feature allows you to select lower driving
gears when the shift lever is in LOW (L). The button
for this mode is located on the left side of the shift
lever knob.
When the shift lever is first moved into the LOW (L)
position, the display in the instrument panel shows L3.
Press the (−) end of the button on the shift lever
once for L2 and once more for L1. Press the (+) end of
the button once each to return to L2, L3 and L4. The
shift lever must be moved back to DRIVE (D) to turn off
the electronic range select mode.

Or you can go to www.helminc.com to order the OM in hard copy.

I have to admit, I've never used the Range Selector on my '04 Maxx (bought new), but now that I live in Charlotte, NC and no longer in West Palm Beach, bet I will. We have hills here....

thanks
