GENERAL MAINTENANCE
1. GENERAL NOTES
Maintenance items may vary from country to country. Check the owner's manual supplement in which
the maintenance schedule is shown.
Every service item in the periodic maintenance schedule must be performed.
Periodic maintenance service must be performed according to whichever interval in the periodic main-
tenance schedule occurs first, the odometer reading (miles) or the time interval (months).
Maintenance service after the last period should be performed at the same interval as before unless
otherwise noted.
Failure to do even one item an cause the engine to run poorly and increase exhaust emissions.
2. WINDSHIELD WASHER FLUID
Check that there is sufficient fluid in the tank.
3. ENGINE COOLANT LEVEL
Check that the coolant level is between the ºFULLº and ºLOWº lines on the see±through reservoir.
4. RADIATOR AND HOSES
(a) Check that the front of the radiator is clean and not blocked with leaves, dirt or bugs.
(b) Check the hoses for cracks, kinks, rot or loose connections.
5. BATTERY ELECTROLYTE LEVEL
Check that the electrolyte level of all battery cells is between the upper and lower level lines on the case.
6. BRAKE AND CLUTCH FLUID LEVELS
(a) Check that the brake and clutch fluid levels are near the upper level line on the see±through reservoirs.
(b) Check that the clutch fluid level is with is ± 5 mm (0.20 in.). of the reservoir hem.
7. ENGINE DRIVE BELTS
Check drive belt for fraying, cracks, wear or oiliness.
8. ENGINE OIL LEVEL
Check the level on the dipstick with the engine turned off.
9. POWER STEERING FLUID LEVEL
Check the level.
The level should be in the ºHOTº or ºCOLDº range depending on the fluid temperature.
10. AUTOMATIC TRANSMISSION FLUID LEVEL
(a) Park the vehicle on a level surface.
(b) With the engine idling and the parking brake applied, shift the selector into all positions from ºPº to ºLº,
and then shift into ºPº position.
(c) Pull out the dipstick and wipe off the fluid with a clean rag. Re±insert the dipstick and check that the
fluid level is in the HOT range.
(d) Do this check with the fluid at normal driving temperature (70 ± 80°C, 158 ± 176°F).
HINT:
Wait until the engine cools down (approx. 30 min.) before checking the fluid level after extended driving at
high speeds, in hot weather, in heavy traffic or pulling a trailer.
11. EXHAUST SYSTEM
If any change in the sound of the exhaust or smell of the exhaust fumes is noticed, have the cause located
and corrected.

Cold Soak Preconditions
The monitor will not run unless:
MIL is OFF.
Fuel level is between 1/2 to 3/4 full (for faster completion)
.
Altitude is 7800 feet (2400 m) or less.
IMPORTANT:
A cold soak must be performed prior to conducting the drive pattern to complete the
Internal Pressure Readiness Monitor.
Cold Soak Procedure
1a. Start the engine and allow ECT (Coolant Temp) to reach 176F (80C) or greater.
(This can be done by letting the engine idle or by driving the vehicle.)
1b. Let the vehicle cold soak for 8 hours or until the difference between IAT (Intake
Air) and ECT (Coolant Temp) is less than 13F (7C).
Example 1
ECT (Coolant Temp) = 75F (24C).
IAT (Intake Air) = 60F (16C).
Difference between ECT (Coolant Temp) and IAT (Intake Air) is 15F (8C).
%The monitor will not run because the difference between ECT (Coolant
Temp) and IAT (Intake Air) is greater than 13F (7C).
Example 2
ECT (Coolant Temp) = 70F (21C).
IAT (Intake Air) = 68F (20C).
Difference between ECT (Coolant Temp) and IAT (Intake Air) is 2F (1C).
%The monitor will run because the difference between ECT (Coolant Temp)
and IAT (Intake Air) is less than 13F (7C).

Drive Pattern Preconditions
The monitor will not run unless:
MIL is OFF.
Fuel level is between 1/2 to 3/4 full (for faster completion)
.
Altitude is 7800 feet (2400 m) or less.
ECT (Coolant Temp) is between 40F and 95F (4.4C ± 35C).
IAT (Intake Air) is between 40F and 95F (4.4C ± 35C).
Cold Soak Procedure has been completed.
NOTE:
Before starting the engine, the difference between ECT (Coolant Temp) and IAT (Intake
Air) must be less than 13F (7C). (Refer to Examples 1 and 2 on previous page.)
Drive Pattern Procedure
Connect the OBDII Scantool to DLC3 to check monitor status and preconditions.
Release the pressure in the fuel tank by removing and then reinstalling the fuel tank
cap.
Start the engine and begin driving as directed.
NOTE:
Do not turn the ignition off until the drive pattern is complete.
Drive on smooth roads to reduce excessive fuel sloshing.
2a. Start the engine and as soon as safely possible begin driving at approximately 45
mph (72km/h) for 5 minutes. (See illustration on previous page.)
2b. Drive the vehicle at approximately 25 mph (40 km/h) for 15 minutes and include a
minimum of two stops for approximately 30 seconds. (See illustration on previous
page.)
The monitor should complete within approximately 20 minutes. If it does not, ensure
preconditions are met and repeat the drive pattern process beginning with the Cold Soak
Procedure.
NOTE:
The readiness status may not switch to ªcompleteº after the first drive pattern trip if a
Pending Code has been set (first trip for a two±trip DTC).
Pending Codes are available from the DTC Info Menu in Enhanced OBDII.
Pending Codes indicate a POTENTIAL problem was detected. A second trip is
needed to confirm the DTC prior to diagnosis.
Once a second trip is completed, a current DTC will be stored. Readiness

Drive Pattern Procedure
Connect the OBDII Scantool to DLC3 to check monitor status and preconditions.
Release the pressure in the fuel tank by removing and then reinstalling the fuel tank
cap.
2a. Start the engine and allow it to idle until ECT (Coolant Temp) is 167F (75C) or
greater. (See illustration on previous page.)
2b. Race the engine at 3,000 rpm for approximately 10 seconds. (See illustration on
previous page.)
2c. Allow the engine to idle with the A/C ON (to create a slight load) for 15 ± 50
minutes. (See illustration on previous page.)
NOTE:
If the vehicle is not equipped with A/C put a slight load on the engine by doing the
following:
Securely set the parking brake.
Block the drive wheels with wheel chocks.
Allow the vehicle to idle in drive for 15 ± 50 minutes.
NOTE:
The readiness status may not switch to ªcompleteº after the first drive pattern trip if a
Pending Code has been set (first trip for a two±trip DTC).
Pending Codes are available from the DTC Info Menu in Enhanced OBDII.
