SERVICING AND MAINTENANCE

SCHEDULED SERVICING

Your vehicle is equipped with an automatic oil change indicator system. The oil change indicator system will remind you that it is time to take your vehicle in for scheduled maintenance. Based on engine operation conditions, the oil change indicator message will illuminate. This means that service is required for your vehicle. Operating conditions such as frequent short trips, trailer tow, extremely hot or cold ambient temperatures, and E85 fuel usage will influence when the “Oil Change Required” message is displayed. Have your vehicle serviced as soon as possible, within the next 500 miles (805 km).

MAINTENANCE PLAN

Refer to the Maintenance Plan for the required maintenance intervals.

At Every Oil Change Interval As Indicated By Oil Change Indicator System

Change oil and filter.

Rotate the tires at the first sign of irregular wear, even if it occurs before the oil indicator system turns on.

Inspect the battery and clean and tighten terminals as required.

Inspect the CV/Universal joints.

Inspect brake pads, shoes, rotors, drums, hoses, and parking brakes.

Inspect engine cooling system protection and hoses.

NOTE:

Under no circumstances should oil change intervals exceed 10,000 miles (16,000 km), 12 months, or 350 hours of engine run time, whichever comes first. The 350 hours of engine run or idle time is generally only a concern for fleet customers.

Once A Month Or Before A Long Trip:

• Check engine oil level.
• Check the windshield washer fluid level.
• Check the tire inflation pressures and look for unusual wear or damage.
• Check the fluid levels of the coolant reservoir, and brake master cylinder, and fill as needed.
• Check the function of all interior and exterior lights.

1. The spark plug change interval is mileage-based only, yearly intervals do not apply.

WARNING!

• You can be badly injured working on or around a motor vehicle. Do only service work for which you have the knowledge and the right equipment. If you have any doubt about your ability to perform a service job, take your vehicle to a competent mechanic.
• Failure to properly inspect and maintain your vehicle could result in a component malfunction and affect vehicle handling and performance. This could cause an accident.

CHECKING OIL LEVEL

To ensure proper engine lubrication, the engine oil must be maintained at the correct level. Check the oil level at regular intervals, such as at every fuel stop. The best time to check the engine oil level is about five minutes after a fully warmed-up engine is shut off.
Checking the oil while the vehicle is on level ground will improve the accuracy of the oil level readings.
There are four possible dipstick types:

• Crosshatched zone.
• Crosshatched zone marked SAFE.
• Crosshatched zone marked with MIN at the low end of the range and MAX at the high end of the range.
• Crosshatched zone marked with dimples at the MIN and the MAX ends of the range.

NOTE:

Always maintain the oil level within the crosshatch markings on the dipstick. Adding 1 qt (1.0 L) of oil when the reading is at the low end of the dipstick range will raise the oil level to the high end of the range marking.

NOTE:
Always maintain the oil level within the crosshatch markings on the dipstick.

NOTE:
Use care when filling under hood fluids such as engine oil, washer fluid, antifreeze, etc., to minimize spillage onto the top of the engine. Any excess fluid that is spilled onto the top of the engine should be removed using compressed air or an absorbent cloth.

ADDING WASHER FLUID

The instrument cluster display will indicate when the washer fluid level is low. When the sensor detects a low fluid level, the Low Washer Fluid Warning Light will illuminate and the “Washer Fluid Low” message will display. The fluid reservoir for the windshield washers and the rear window washer is shared. The fluid reservoir is located in the engine compartment, be sure to check the fluid level at regular intervals. Fill the reservoir with windshield washer solvent only (not radiator antifreeze). When refilling the washer fluid reservoir, take some washer fluid and apply it to a cloth or towel and wipe clean the wiper blades, this will help blade performance. To prevent freeze-up of your windshield washer system in cold weather, select a solution or mixture that meets or exceeds the temperature range of your climate. This rating information can be found on most washer fluid containers.

NOTE:

Use care when filling under hood fluids such as engine oil, washer fluid, antifreeze, etc., to minimize spillage onto the top of the engine. Any excess fluid that is spilled onto the top of the engine should be removed using compressed air or an absorbent cloth.

WARNING!

Commercially available windshield washer solvents are flammable. They could ignite and burn you. Care must be exercised when filling or working around the washer solution.

CAUTION!

Do not travel with the windshield washer fluid reservoir empty: the windshield washers are essential for improving visibility.

MAINTENANCE-FREE BATTERY

Your vehicle is equipped with a maintenance-free battery. Water will never have to be added, and periodic maintenance is not required.

WARNING!

• Battery fluid is a corrosive acid solution and can burn or even blind you. Do not allow battery fluid to contact your eyes, skin, or clothing. Do not lean over a battery when attaching clamps. If acid splashes in the eyes or on the skin, flush the area immediately with large amounts of water. Refer to Jump Starting Procedure Ú page 278.
• Battery gas is flammable and explosive. Keep flame or sparks away from the battery. Do not use a booster battery or any other booster source with an output greater than 12 Volts. Do not allow cable clamps to touch each other.
• Battery posts, terminals, and related accessories contain lead and lead compounds. Wash hands after handling.

CAUTION!

• It is essential when replacing the cables on the battery that the positive cable is attached to the positive post and the negative cable is attached to the negative post. Battery posts are marked positive (+) and negative (-) and are identified on the battery case. Cable clamps should be tight on the terminal posts and free of corrosion.
• If a “fast charger” is used while the battery is in the vehicle, disconnect both vehicle battery cables before connecting the charger to the battery. Do not use a “fast charger” to provide a starting voltage.

PRESSURE WASHING

Cleaning the engine compartment with a high-pressure washer is not recommended.

CAUTION!

Precautions have been taken to safeguard all parts and connections however, the pressures generated by these machines are such that complete protection against water ingress cannot be guaranteed.

VEHICLE MAINTENANCE

An authorized dealer has the qualified service personnel, special tools, and equipment to perform all service operations in an expert manner. Service Manuals are available which include detailed service information for your vehicle. Refer to these Service Manuals before attempting any procedure yourself.

NOTE:

Intentional tampering with emissions control systems may void your warranty and could result in civil penalties being assessed against you.

WARNING!

You can be badly injured working on or around a motor vehicle. Only do service work for which you have the knowledge and the proper equipment. If you have any doubt about your ability to perform a service job, take your vehicle to a competent mechanic.
