give you extra traction. It sends the maximum power
to all four wheels. You might choose 4LO if you
were driving off-road in sand, mud or deep snow and
climbing or descending steep hills.

you are in. The indicator lights will come on brie y when
you turn on the ignition and one will stay on. If the
lights do not come on, you should take your vehicle in
