Maintenance and Specifications
Readiness for Inspection/Maintenance (I/M) testing
In some localities, it may be a legal requirement to pass an I/M test of
the on-board diagnostics system. If the indicator is on, refer to the
description in the Warning lights and chimes section of the
Instrument Cluster chapter. Your vehicle may not pass the I/M test with
the indicator on.
If the vehicle's powertrain system or its battery has just been serviced,
the on-board diagnostics system is reset to a "not ready for I/M test"
condition. To ready the on-board diagnostics system for I/M testing, a
minimum of 30 minutes of city and highway driving is necessary as
described below:
• First, at least 10 minutes of driving on an expressway or highway.
• Next, at least 20 minutes driving in stop-and-go, city-type traffic with
at least four idle periods.
Allow the vehicle to sit for at least eight hours without starting the
engine. Then, start the engine and complete the above driving cycle. The
engine must warm up to its normal operating temperature. Once started,
do not turn off the engine until the above driving cycle is complete.
POWER STEERING FLUID
Check the power steering fluid.
Refer to the scheduled
maintenance information for the
service interval schedules. If adding
fluid is necessary, use only
MERCON ATF.
1. Start the engine and let it run
until it reaches normal operating
temperature (the engine coolant
temperature gauge indicator will be near the center of the normal area
between H and C).
2. While the engine idles, turn the steering wheel left and right several
times.
3. Turn the engine off.
