Normal Service Defined

Follow the NORMAL schedule only if none of the conditions from the SEVERE schedule apply.

NOTE: Some vehicle manufacturers provide only a single schedule (Normal) for all driving conditions. Some of the components listed in the schedule may have notes describing alternate service intervals for that component depending on driving conditions, see Example.

Example:
Many vehicles have an "Engine Oil Life Monitor" lamp which can illuminate anytime between intervals depending on driving conditions. The oil should then be replaced at that time, regardless of mileage, and the "Engine Oil Life Monitor" reset.
