How to Set the Clock on a 2001 Chevy Impalaby Justin Cupler
The 2002 Chevrolet Impala came in a pair of trim levels -- Base and LS -- and both models came with an audio system as standard equipment. The Base model came with an AM-FM audio system with four speakers, and the LS model added a cassette player and two more speakers. Both radios featured a clock, and resetting the clock on these radios is fairly simple.
Setting the Clock on a Standard Radio
With the ignition on or off, press and hold the "HR" or "MIN" arrow on the bottom, right of the radio for two seconds to enter the set mode. Press and release the "HR" arrow until the correct hour displays on the screen, then press and release the "MIN" arrow until the correct minute displays on the screen.
Setting the Clock With Radio Data System
With the ignition on or off, press and hold the "HR" or "MN" button just under the tuner knob on the radio for two seconds until a clock emblem shows on the tuner display. Hold the "HR" button until the hour that you desire shows on the screen -- a.m. and p.m. will cycle automatically each time the clock reaches 12:00 -- then hold down the "MN" button until the minute that you desire shows on the screen.
Setting the Clock to an FM Station's Time
Tune to a station that broadcasts Radio Data System, then press and hold the "HR" and "MN" buttons until "UPDATED" appears on the screen. If the station is not broadcasting the time, "NO UPDAT" will show on the screen and you will need to tune to another station to obtain the time.
