What does the warning light "power" mean?

there is a power switchon the shifter console that gives you extra power for going up hills etc..the "power" light on dash is just indicating the power switch is on

How do u turn it off

were is power switch located inside tracker?

Its a switch to the left of the shift knob. Says N A/T P on it

When I push that button it says overdrive on overdrive off it does not turn the power word off on the dash

Mine is 2002 Chevy Tracker, with Power light on, won't go off. any help would be appreciated
