- Driving less than 16 Kilometers (10 miles) per trip.
- Driving in temperatures over 32°C (90°F).
- Extensive idling or long periods of stop and go driving.
- Driving roof-top carrier or driving in mountainous conditions.

NORMAL SERVICE

- Use the normal service intervals if the vehicle is primarily operated under conditions other than those listed above.

Notes on "Severe Service"
Some vehicle manufacturers provide separate maintenance procedures for vehicles operated under Severe or Special circumstances. Other manufacturers provide recommendations for service at more frequent intervals for vehicles operated under severe conditions. For any vehicle operated under severe conditions, as defined by the vehicles manufacturer, always check the regular maintenance schedule for procedures that may not appear at the similar interval under severe service.

Example:
Manufacturer recommends tire rotation at 10,000 mile intervals under regular maintenance.
There is no tire rotation recommendation shown in the severe service schedule, which has 3,000 mile intervals.

At a minimum, recommend rotation at 9,000 and 18,000 mile intervals etc., or as close to the regular schedule as possible. Depending on vehicle usage and obvious tire wear, this recommendation should be increased as necessary.
