Cadillac Maintenance Schedule Guide

Tire Rotation and Required Services Every 12 000 km (7,500 mi)
Tires are rotated to achieve a more uniform wear for all tires. The first rotation is the most important.

Anytime unusual wear is noticed, rotate the tires as soon as possible, check for proper tire inflation pressure, and check for damaged tires or wheels. If the unusual wear continues after the rotation, check the wheel alignment.

• Perform Multi-Point Vehicle Inspection.
• Lubricate body components.

Additional Required Services — Normal Service Every 12 000 km (7,500 mi)

• Check the engine oil level and oil life percentage. If needed, change engine the oil and filter, and reset oil the life system. Or when the CHANGE ENGINE OIL SOON message displays, have the engine oil and filter changed within the next 1000 km/600 mi. If driven under the best conditions, the engine oil life system may
  not indicate the need for vehicle service for up to a year. The engine oil and filter must be changed at least once a year and
  the oil life system must be reset. Your trained dealer technician can perform this work. If the engine oil life system is reset accidentally, service the vehicle within 5000 km/3,000 mi since the last service.

Reset the oil life system when the oil is changed.

• When the REPLACE AT NEXT OIL CHANGE message displays, the engine air filter should be replaced at the next engine oil change. When the REPLACE ENGINE AIR FILTER SOON message displays, the engine air filter should be replaced at the earliest convenience. Reset the engine air filter life system after the engine air filter is replaced.

Every 36 000 km (22,500 mi)

• Replace the passenger compartment air filter. Or every 24 months, whichever comes first. More frequent passenger compartment air filter replacement may be needed if driving in areas with heavy traffic, poor air quality, high dust levels, or environmental allergens. Passenger compartment air filter replacement may be needed if there is reduced airflow, window fogging, or odors. Your GM dealer can help determine when to replace the filter.

Every 96 000 km (60,000 mi)

• Replace spark plugs. (2.0L L4 Engine Only.)
• Inspect spark plug wires and/or boots.

Every 156 000 km (97,500 mi)

• Replace spark plugs. (3.6L V6 Engine Only.) Inspect spark plug wires and/or boots.

Every 161 000 km (100,000 mi)

• Replace hood and/or body lift support gas struts. Or every 10 years, whichever comes first.

Every 240 000 km (150,000 mi)

• Change rear axle fluid, if equipped with AWD. Do not directly power wash the transfer case and/or front/rear axle output seals. High pressure water can overcome the seals and contaminate the transfer case fluid. Contaminated fluid will decrease the life of the transfer case and/or axles and should be replaced.
• Drain and fill engine cooling system. Or every six years, whichever comes first.

Severe Conditions Requiring More Frequent Maintenance*

• Public service, military, or commercial use vehicles to include the following:
• Ambulances, police cars, and emergency rescue vehicles.
• Civilian vehicles such as light duty pick-up trucks, SUVs, and passenger cars that are used in military applications.
• Recovery vehicles such as tow trucks and flatbed single vehicle carriers or any vehicle that is consistently used in towing trailers or other loads.
• High use commercial vehicles such as courier delivery vehicles, private security patrol vehicles, or any vehicles that operate on a 24–hour basis.
• Any vehicle consistently operated in am high sand or dust environment such as used on oil pipelines and similar applications.
• Vehicles that are regularly used for short trips of 6 km (4 mi) or less.

The oil life indicator will show you when to change the oil and filter. Under severe conditions the indicator may come on before 12 000 km (7,500 mi).

Footnote: Under extreme driving conditions listed above, it may be
necessary to replace your spark plugs at more frequent intervals. For further assistance in determining the most suitable service maintenance intervals for your vehicle, please contact your authorized GM Dealer.

Extreme service is for vehicles mainly driven off-road in four-wheel drive or used in farming, mining, forestry, or snow plowing.

Additional Required Services — Severe Service Every 72 000 km (45,000 mi)

• Change automatic transmission fluid.

Every 120 000 km (75,000 mi)

• Change rear axle fluid, if equipped with AWD. Do not directly power wash the transfer case and/or front/rear axle output seals. High pressure water can overcome the seals and contaminate the  transfer case fluid. Contaminated fluid will decrease the life of the transfer case and/or axles and should be replaced.

Owner Checks and Services Every Five Years

• Replace brake fluid every five years.

Every Seven Years

• Replace Air Conditioning Desiccant and perform air conditioning system maintenance every seven years. This service requires replacement of the desiccant to help the longevity and efficient operation of the air conditioning system. This service can be complex.

Multi-Point Vehicle Inspection (MPVI)
