When towing, gear must be shift to "N' by releasing gear shift lock, else must use baby wheel on the front wheel for fwd car. Now car with electronic parking brake even more trickier on how to release the car from 'P' when electric off. Nowadays proton normally won't do towing, they ask u to call your insurance.
Normally the tow truck guy will know how, add baby wheel need to add $$.
