We investigate the 2-3µm ISO-SWS spectrum of the luminous protostellar object S 140:IRS1. Two narrow absorption features are detected at 2.70 and 2.77µm, which are well fitted with laboratory spectra of the ν₁+ν₃ and the 2ν₂+ν₃ combination modes of solid cotwo. The ice in this line of sight must have been subjected to significant heating, in agreement with previously studied CO₂ bands. A combined laboratory fit to all CO₂ bands detected toward S 140:IRS1 shows, among others, the need for particle shape calculations for the CO₂ stretch mode. Finally, we discuss the absence of features of isolated H₂O and dangling OH groups in the spectrum of S 140:IRS1
