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.
If the service engine soon indicator is on or the bulb does not
work, the vehicle may need to be serviced. SeeOn-board
Diagnostics (OBD-II)in this chapter.
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 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 or 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 the
engine is 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.

AUTOMATIC TRANSMISSION (IF EQUIPPED)
WARNING:Always set the parking brake fully and make sure
the gearshift is latched in position P. Turn the ignition off and
remove the key whenever you leave your vehicle.
Your vehicle has been designed to improve fuel economy by reducing
fuel usage while coasting or decelerating. When you take your foot off
the accelerator pedal and the vehicle begins to slow down, the torque
converter clutch locks up and aggressively shuts off fuel flow to the
engine while decelerating. This fuel economy benefit may be perceived
as a light to medium braking sensation when removing your foot from
the accelerator pedal.
Position P
This position locks the transmission and prevents
the front wheels from turning.
To put your vehicle in gear:
•Press the brake pedal.
•Move the gearshift lever into the desired gear.
To put your vehicle in position P:
•Come to a complete stop.
•Move the gearshift lever and securely latch it in position P.
Position R
With the gearshift lever in position R, the vehicle will move backward.
Always come to a complete stop before shifting into and out of position R.
Position N
With the gearshift lever in position N, the vehicle can be started and is
free to roll. Hold the brake pedal down while in this position.
Position D with overdrive
The normal driving position for the best fuel economy. The transmission
operates in gears one through six. The automatic transmission shift
strategy has the ability to detect hilly terrain or mountainous areas and
will provide a limited amount of grade assist features automatically.

Position S
Moving the gearshift lever to position:
•Provides additional grade (engine) braking and extends lower gear
operation to enhance performance for uphill climbs, hilly terrain or
mountainous areas. This will increase engine RPM during engine
braking.
•Provides additional lower gear operation through the automatic
transmission shift strategy which reacts to vehicle inputs (vehicle
acceleration, accelerator pedal, brake pedal and vehicle speed).
•Gears are selected more quickly and at higher engine speeds.
Note:The system will stay in position S until the gear shift lever is
moved into another gear for example position P or position D.
SelectShift Automatic® Transmission
Your SelectShift automatic transmission gives you the ability to manually
change gears if you would like. To use SelectShift, move the gearshift
lever into position S. Now you can use the thumb toggle on the side of
your gearshift lever to select gears.
•Press (+) on the gearshift lever
to manually upshift the
transmission.
•Press (–) on the gearshift lever
to manually downshift the
transmission.
The information display in the instrument cluster will show the selected
gear you are currently in.
In order to prevent the engine from running at too low an RPM, which
may cause it to stall, SelectShift will automatically make some downshifts
even if it has determined that you have not downshifted in time.
Although the SelectShift will make some downshifts for you, it will still
allow you to downshift at any time as long as the SelectShift determines
that the engine will not be damaged from over-revving.
Note:Engine damage may occur if excessive engine revving is held
without shifting.

Note:Some models have a blink feature (if equipped). If manually
selecting a gear that is out of the current vehicle speed range, the
vehicle will not make the requested shift and will blink the current gear.
Brake-shift interlock
WARNING:Do not drive your vehicle until you verify that the
brakelamps are working.
WARNING:When doing this procedure, you will be taking the
vehicle out of park which means the vehicle can roll freely. To
avoid unwanted vehicle movement, always fully set the parking brake
prior to doing this procedure. Use wheel chocks if appropriate.
WARNING:If the parking brake is fully released, but the brake
warning lamp remains illuminated, the brakes may not be
working properly. Contact your authorized dealer as soon as possible to
have the system serviced immediately.
This vehicle is equipped with a brake-shift interlock feature that prevents
the gearshift lever from being moved fromP(Park) when the ignition is
in the on position unless the brake pedal is pressed.
If you cannot move the gearshift lever out ofP(Park) with the ignition
on and the brake pedal pressed:
1. Apply the parking brake.
2. Using a flat head screwdriver or
similar tool, remove the chrome
bezel at the base of the gearshift
lever.

If it is necessary to use the above procedure to move the gearshift lever,
it is possible that a fuse has blown or the vehicle’s brake lamps are not
operating properly. Refer to theFuseschapter.
If Your Vehicle Gets Stuck in Mud or Snow
Note:Do not rock the vehicle if the engine is not at normal operating
temperature or damage to the transmission may occur.
Note:Do not rock the vehicle for more than a minute or damage to the
transmission and tires may occur, or the engine may overheat.
If your vehicle gets stuck in mud or snow, it may be rocked out by
shifting between forward and reverse gears, stopping between shifts
in a steady pattern. Press lightly on the accelerator in each gear.

MANUAL TRANSMISSION (IF EQUIPPED)
Using the Clutch
Manual transmission vehicles have a starter interlock that prevents
starting the engine unless the clutch pedal is fully pressed.
To start the vehicle:
1. Make sure the parking brake is fully set.
2. Press the clutch pedal to the
floor, then put the gearshift lever in
the neutral position.
3. Start the engine.
4. Press the brake pedal and move
the gearshift lever to the desired
gear; position 1 or position R.
5. Release the parking brake, then
slowly release the clutch pedal
while slowly pressing on the
accelerator.
During each shift, the clutch pedal must be fully pressed to the floor.
Make sure the floor mat is properly positioned so it does not interfere
with the full extension of the clutch pedal.
Note:Failure to fully press the clutch pedal to the floor may cause
increased shift efforts, prematurely wear transmission components or
damage the transmission.
Note:Do not drive with your foot resting on the clutch pedal or use the
clutch pedal to hold your vehicle at a standstill while waiting on a hill.
These actions will reduce the life of the clutch.
