(subject to availability of cellular and GPS signals).
A voice connection between the Roadside Assistance 
dispatcher and the occupants of the vehicle will be 
established. The nature of the need for assistance can

or towing charges may apply. Refer to the Roadside 
Assistance manual for more information.
