Switching off AdvanceTrac  with RSC 
If the vehicle is stuck in snow, mud or sand, and seems to lose engine
power, switching off certain features of the AdvanceTrac  with RSC 
system may be beneficial because the wheels are allowed to spin. This
will restore full engine power and will enhance momentum through the
obstacle. To switch off the AdvanceTrac  with RSC  system, press the
stability control button located on the instrument panel to the right of
the climate control system. Full features of the AdvanceTrac  with RSC 
system can be restored by pressing the button again or by turning off
and restarting the engine.
If you switch off the AdvanceTrac  with RSC  system, the stability
control off light will illuminate steadily. Pressing the stability control
button again will turn off the stability control off light and reactivate the
system.
In R (Reverse), ABS and the engine traction control and brake traction
control features will continue to function; however, ESC and RSC  are
disabled.

Readiness for Inspection/Maintenance (I/M) testing
Some state/provincial and local governments may have
Inspection/Maintenance (I/M) programs to inspect the emission control
equipment on your vehicle. Failure to pass this inspection could prevent
you from getting a vehicle registration. Your vehicle may not pass the I/M
test if the service engine soon indicator is on or not working
properly (bulb is burned out), or if the OBD-II system has determined
that some of the emission control systems have not been properly
checked. In this case, the vehicle is considered not ready for I/M testing.
If the service engine soon indicator is on or the bulb does not
work, the vehicle may need to be serviced. Refer to On-board
diagnostics (OBD-II) in this chapter.
If the vehicle’s engine or transmission has just been serviced, or the
battery has recently run down or been replaced, the OBD-II system may
indicate that the vehicle is not ready for I/M testing. To determine if the
vehicle is ready for I/M testing, turn the ignition key to the on position
for 15 seconds without cranking the engine. If the service engine
soon indicator blinks eight times, it means that the vehicle is not
ready for I/M testing; if the service engine soon indicator stays on
solid, it means that the vehicle is ready for I/M testing.
The OBD-II system is designed to check the emission control system
during normal driving. A complete check may take several days. If the
vehicle is not ready for I/M testing, the following driving cycle consisting
of mixed city and highway driving may be performed:
15 minutes of steady driving on an expressway/highway followed by
20 minutes of stop-and-go driving with at least four 30-second 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. If
the vehicle is still not ready for I/M testing, the above driving cycle will
have to be repeated.Maintenance and Specifications
