MAINTAINING YOUR VEHICLE

MAINTENANCE PROCEDURES

For information on the maintenance procedures for your vehicle, please refer to
"Maintenance Procedures" in "Maintaining Your Vehicle" in your Owner's Manual or
applicable supplement on the DVD for further details.
MAINTENANCE SCHEDULE — GASOLINE ENGINE
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. Severe Operating Conditions can cause the change oil message to
illuminate as early as 3,500 miles (5,600 km) since last reset. Have your vehicle
serviced as soon as possible, within the next 500 miles (805 km).
Your authorized dealer will reset the oil change indicator message after completing
the scheduled oil change.
NOTE:
Under no circumstances should oil change intervals exceed 10,000 miles
(16,000 km) or twelve months, whichever comes first.
Severe Duty All Models
• Change Engine Oil at 4000 miles (6,500 km) if the vehicle is operated in a dusty
and off road environment. This type of vehicle use is considered Severe Duty.
• Rear Air Spring Cleaning (if equipped with Quadra Lift air suspension system): If
operating the vehicle in/on severe cold, gravel roads, muddy environments, dusty
environments, and/or off road conditions, the rear air suspension components
should be cleaned every 10,000 miles (16,093 km) to prevent damage to the
system. This type of vehicle use is considered Severe Duty. Because this cleaning
procedure requires special tools it is recommended that you take your vehicle to an
authorized dealer for service to prevent system damage.
Once A Month Or Before A Long Trip:
• Check engine oil level
• Check windshield washer fluid level
• Check the tire inflation pressures and look for unusual wear or damage
• Check the fluid levels of the coolant reservoir, brake master cylinder and power
steering, and fill as needed.
