How do you turn on the driving lights a 2002 jeep grand Cherokee?

The 2002 Jeep Grand Cherokee's driving lights (also sometimes called fog lights) are usually controlled by a separate switch. You won't turn them on with the headlights.

Look for a switch on the dashboard, often near the headlight switch. It might be a small button or a rocker switch, and it may be labeled "FOG" or have a symbol depicting fog lights (two small circles).

If you can't find a dedicated switch, consult your owner's manual. The location and operation of the fog lights will be clearly described there.
