Lubrication & Maintenance: Maintenance Jeep Commander I

FLUID TYPES

When service is required, DaimlerChrysler Corporation recommends that only Mopar® brand parts, lubricants and chemicals be used. Mopar® provides the best engineered products for servicing DaimlerChrysler Corporation vehicles.

Only lubricants bearing designations defined by the following organization should be used to service a DaimlerChrysler Corporation vehicle

1. Society of Automotive Engineers (SAE)
2. American Petroleum Institute (API). (Scheme 2)
3. National Lubricating Grease Institute (NLGI)
4. European Automobile Manufacturers Association (ACEA)

Scheme 2

This symbol on the front of an oil container means that the oil has been certified by the American Petroleum Institute (API) to meet all the lubrication requirements specified by DaimlerChrysler Corporation.

BRAKE FLUID - BUX

The brake fluid used in this vehicle must conform to DOT 3 specifications and SAE J1703 standards. If DOT 3 brake fluid is not available, brake fluid conforming to DOT 4 specifications may be used in its place. The fluids are compatible, but DOT 4 usage may require additional fluid maintenance. No other type of brake fluid is recommended or approved for usage in the vehicle brake system. Use only Mopar® Brake Fluid DOT 3 Motor Vehicle or equivalent from a tightly sealed container.

AUTOMATIC TRANSMISSION FLUID

Note. Refer to Service Procedures in this service information for fluid level checking procedures.

Mopar® ATF +4, Automatic Transmission Fluid is the recommended fluid for DaimlerChrysler automatic transmissions.

Dexron II fluid IS NOT recommended. Clutch chatter can result from the use of improper fluid.

Mopar® ATF +4, Automatic Transmission Fluid when new is red in color. The ATF is dyed red so it can be identified from other fluids used in the vehicle such as engine oil or antifreeze. The red color is not permanent and is not an indicator of fluid condition. As the vehicle is driven, the ATF will begin to look darker in color and may eventually become brown. This is normal. ATF+4 also has a unique odor that may change with age. Consequently, odor and color cannot be used to indicate the fluid condition or the need for a fluid change.

FLUID ADDITIVES

DaimlerChrysler strongly recommends against the addition of any fluids to the transmission, other than those automatic transmission fluids listed above. Exceptions to this policy are the use of special dyes to aid in detecting fluid leaks.

Various "special" additives and supplements exist that claim to improve shift feel and/or quality. These additives and others also claim to improve converter clutch operation and inhibit overheating, oxidation, varnish, and sludge. These claims have not been supported to the satisfaction of DaimlerChrysler and these additives must not be used. The use of transmission "sealers" should also be avoided, since they may adversely affect the integrity of transmission seals.

POWER STEERING FLUID

This system requires the use of hydraulic system/power steering fluid which meets DaimlerChrysler specification MS-10838, or equivalent. DO NOT MIX POWER STEERING FLUID TYPES. Damage may result to the power steering pump and system if any other fluid is used, and DO NOT OVERFILL.

BRAKE FLUID

The brake fluid used in this vehicle must conform to DOT 3 specifications and SAE J1703 standards. No other type of brake fluid is recommended or approved for usage in the vehicle brake system. Use only Mopar brake fluid or an equivalent from a tightly sealed container.

The automatic transmission fluid is selected based upon several qualities. The fluid must provide a high level of protection for the internal components by providing a lubricating film between adjacent metal components. The fluid must also be thermally stable so that it can maintain a consistent viscosity through a large temperature range. If the viscosity stays constant through the temperature range of operation, transmission operation and shift feel will remain consistent. Transmission fluid must also be a good conductor of heat. The fluid must absorb heat from the internal transmission components and transfer that heat to the transmission case.

FLUID FILL/CHECK LOCATIONS

The fluid fill/check locations and lubrication points are located in each applicable group.

MAINTENANCE SCHEDULES - EXPORT - DIESEL

There are two maintenance schedules that show the required service for your vehicle.

First is Schedule "A" . It is for vehicles that are not operated under any of the conditions listed under Schedule "B" .

Second is Schedule "B" . It is for vehicles that are operated under the conditions that are listed below and at the beginning of the schedule.

1. Day or night temperatures are below 0°C (32°F).
2. Stop and go driving.
3. Extensive engine idling.
4. Driving in dusty conditions.
5. Short trips of less than 16.2 km (10 miles).
6. More than 50% of your driving is at sustained high speeds during hot weather, above 32°C (90°F).
7. Trailer towing.
8. Taxi, police, or delivery service (commercial service).
9. Off-road or desert driving.

Note. Most vehicles are operated under the conditions listed for Schedule "B" .

Use the schedule that best describes your driving conditions. Where time and mileage are listed, follow the interval that occurs first.

At Each Stop for Fuel

1. Check the engine oil level about 5 minutes after a fully warmed engine is shut off. Checking the oil level while the vehicle is on level ground will improve the accuracy of the oil level reading. Add oil only when the level is at or below the ADD or MIN mark.
2. Check the windshield washer solvent, add as required.

Once a Month

1. Check the tire pressure and look for unusual wear or damage.
2. Inspect the battery, clean and tighten the terminals as required.
3. Check the fluid levels of engine coolant/anti-freeze deaeration bottle, brake master cylinder, and transmission, and add as needed.
4. Check all lights and all other electrical items for correct operation.

At Each Oil Change

1. Change the engine oil filter.
2. Inspect the exhaust system.
3. Inspect brake hoses.
4. Check the engine coolant/anti-freeze level, hoses, and clamps.
5. Inspect engine accessory drive belts. Replace as necessary.
6. Inspect for the presence of water in the fuel filter/water separator unit.
