SCHEDULED MAINTENANCE
When the Change Engine Oil Soon Message Displays
Change engine oil and filter. An Emission Control Service.
When the Change Engine Oil Soon message displays, service is required for the vehicle as soon as possible, within the next 1 000 km/600 miles. If driving under the best conditions, the engine oil life system might not indicate the need for vehicle service for more than a year. The engine oil and filter must be changed at least once a year and the oil life system must be reset. If the engine oil life system is reset accidentally, service the vehicle within 5 000 km/3,000 miles since the last service. Reset the oil life system whenever the oil is changed. Refer to Service Reminder Indicators.
When the Change Engine Oil Soon message displays, certain services, checks, and inspections are required. The services described for Maintenance I should be performed at every engine oil change. The services described for Maintenance II should be performed when:
• Maintenance I was performed the last time the engine oil was changed.
• It has been 10 months or more since the Change Engine Oil Soon message has displayed or since the last service.
Maintenance I
Change engine oil and filter. An Emission Control Service.
Engine coolant level check.
Windshield washer fluid level check.
Tire inflation check.
Tire wear inspection.
Rotate tires.
Fluids visual leak check (or every 12 months, whichever occurs first). A leak in any system must be repaired and the fluid level checked.
Engine air cleaner filter inspection (vehicles driven in dusty conditions only).
Brake system inspection (or every 12 months, whichever occurs first).
For vehicles with Allison Transmission� only: At the first engine oil change only, replace external transmission filter.
Maintenance II
Perform all services described in Maintenance I.
Steering and suspension inspection. Visually inspect front and rear suspension and steering system for damaged, loose, or missing parts, signs of wear or lack of lubrication. Inspect power steering lines and hoses for proper hook-up, binding, leaks, cracks, chafing, etc.
Lubricate the front suspension, steering linkage, rear driveline center splines, and parking brake cable guides. Vehicles used under severe commercial operating conditions require lubrication on a regular basis every 5 000 km/3,000 miles.
Engine cooling system inspection. Visual inspection of hoses, pipes, fittings, and clamps and replacement, if needed.
Windshield wiper blade inspection for wear, cracking, or contamination and windshield and wiper blade cleaning, if contaminated.
Body components lubrication. Lubricate all key lock cylinders, body door hinges, hood latch assembly, secondary latch, pivots, spring anchor, release pawl, fuel door hinge, locks, latches, and any folding or moving seat hardware. Lubricate hood hinges and rear compartment hinges. More frequent lubrication may be required when vehicle is exposed to a corrosive environment. Applying silicone grease on weatherstrips with a clean cloth makes them last longer, seal better, and not stick or squeak.
Restraint system component check. Check that the safety belt reminder light, safety belts, buckles, latch plates, retractors and anchorages are working properly. Look for any other loose or damaged safety belt system parts that might keep a safety belt system from doing its job. Torn or frayed safety belts may not protect you in a crash. They can rip apart under impact forces. If a belt is torn or frayed, get a new one right away. Make sure the safety belt reminder light is working. Keep safety belts clean and dry. The airbag system does not need regularly scheduled maintenance or replacement. Make sure the airbag readiness light is working.
Notice: If an airbag covering is damaged, opened, or broken, the airbag may not work properly. Do not open or break the airbag coverings. If there are any opened or broken airbag covers, have the airbag covering and/or airbag module replaced.
Automatic transmission fluid level check and adding fluid, if needed.
Engine air cleaner filter inspection.
Vehicles with GVWR above 4 536 kg (10,000 lbs): Shields inspection for damage or looseness. Adjust or replace as required. This is a Noise Emission Control Service. Applicable to vehicles sold in the United States and recommended for vehicles sold in Canada.
Air intake system check. Check the air intake system installation to assure that gaskets are properly sealed and that all hose connections, fasteners, and other components are tight. Also check to be sure that the air cleaner housing is properly seated and the cover fits tightly. Tighten connections and fasteners or replace damaged parts as necessary. This is a Noise Emission Control Service. Applicable to vehicles sold in the United States and recommended for vehicles sold in Canada.
Fuel filter service. An Emission Control Service. If the two chassis mounted fuel filters have not been replaced, or if the vehicle has been driven 32 000 km (20,000 miles) or more since the fuel filters were last replaced, replace both fuel filters.
Additional Required Services
At Each Fuel Stop
Engine oil level check.
Engine coolant level check.
Windshield washer fluid level check.
Once a Month
Tire inflation check.
Tire wear inspection.
Once a Year
Starter switch check. Owners Checks and Services
Parking brake and automatic transmission P (Park) mechanism check. Owners Checks and Services
Automatic transmission shiftlock control system check. Owners Checks and Services

Throttle system inspection for interference, binding or for damaged or missing parts. Replace parts as needed. Replace any components that have high effort or excessive wear. Do not lubricate accelerator or cruise control cables.
Exhaust system, including DPF pressure lines, inspection. Check to be sure that mud or dirt is not caked on the exhaust system, especially in the area of the diesel particulate filter and tailpipe. Clean the area as needed. At high mileages, the DPF becomes loaded with ash. This is normal. When the amount of ash loading is high, perform DPF cleaning or replacement.
