Your daughter’s Chevy Cruze may have cruise control, depending on which trim level and model year she has. The Chevy Cruze LT, LTZ, and Premier all have cruise control, but these trims vary from year to year. The only Cruze trims that certainly won’t have cruise control are the L and LS trims.
If you’re still at a loss, just tell your daughter to look at the steering wheel. Cruze models equipped with cruise control will have buttons on the left-hand side of the steering wheel. They should be obvious, even to someone who doesn’t know much about a vehicle or cruise control.
