How Do I Set the Clock on a 1998 Chevrolet?by Leonardo R. Grabkowski
Chevrolet vehicles manufactured in 1998 came with either an automatic tone control radio or a standard radio. Setting the clock is the same in all 1998 Chevrolet vehicles, including the Cavalier, Suburban, Tahoe, Camaro and Corvette. The vehicle must be turned on while you set the clock. You might need to set the clock if you move to a different time zone, or if you have replaced the Chevrolet's battery, which would cause the clock to reset.
