i think error in pinyin scipt

hi, i think theres an error in the pinyin script in 2.4. isn't 'to fasten' 系好 spelled xihao instead of jihao. i just wanted to point it out and tell you guys

According to the Oxford Chinese Dictionary "fasten seatbelt" is "jihao anquandai".

“系” 是一个多音字. 这个情况下该说 jì hǎo "Xi" is a multiple sound character. In this case, jì hǎo is correct
