I've lost my pit crew...How to switch them back on???

[Jack Stand]

Somehow I've switched off my pit crew...No stop sign is dropped and no crew is visible??
Can some one help me ???
thanks

settings -> CSP -> track adjustments -> crew

Thank you Hoksu....
I have that switched on and the crew changes tires etc...
I used to have a crew member who waved the red "stop" sign upon entering pits....can't seem to get that back working.
It is not a big deal but was just wondering what I did to loose that.
thanks again. (csp ver 1.60)
