If a customer arrives to the dealer with no appointment scheduled, it is recommended for the dealer to
offer alternative transportation to the customer.
If customer schedules an appointment in advance, ensure the appropriate tools and equipment are onhand to perform any related repairs.
Always inquire if the customer will have time for an additional service to be performed if they were
originally scheduled for a different service.
Offer SRC assistance for customers who may be pressed on time.
Be honest with customers on wait times.
If the service is taking longer than expected, update the customer.
If you are unsure of certain processes, don’t guess. Take time to familiarize yourself with the proper
procedures or ask for help/clarity from your teammates or leadership.
If you see a team member having trouble addressing the concern, ask if you can provide some help.

Recommended Alternative Transportation

addition, a SRC may be required based on the repair procedure duration and any other additional work on the
vehicle that may need to be addressed during customer’s visit. If a SRC is not available, other options such as a
