Question: Light on dash came on, it is arrow pointing up and it is under the milage and RPM gages.

I was at stop, waiting maybe 3-4 mins with car in park, I shifted into drive and that light came on and stayed on the 5-6 miles home. I turned car off and restarted and it didn't come on again.......... but what is that light for? Thanks so much.

Somehow I engaged the steep, mtn gear. The above happened late at night after waiting for a train. - It is found in drive 2. Would this also be "overdrive"? Meaning extra boost to drive up Mtns for skiing?


PS I bought car used and it never had a users manual.
Do you know of one on-line?
Or which (cheapest) book would you recommend?
