NOTE:
Vehicles equipped with Quadra-Lift must be placed in Transport Mode before tying
them down (from the body) on a trailer or flatbed truck. If the vehicle cannot be
placed in Transport mode (for example, engine will not run), tie-downs must be
fastened to the axles (not to the body). Failure to follow these instructions may cause
fault codes to be set and/or cause loss of proper tie-down tension.
Two-Wheel Drive Models
DO NOT flat tow this vehicle. Damage to the drivetrain will result.
Recreational towing (for two-wheel drive models) is allowed ONLY if the rear wheels
are OFF the ground. This may be accomplished using a tow dolly or vehicle trailer. If
using a tow dolly, follow this procedure:
1. Properly secure the dolly to the tow vehicle, following the dolly manufacturer's
instructions.
2. Drive the rear wheels onto the tow dolly.
3. Firmly apply the parking brake. Shift the transmission into PARK.
4. Turn the ignition switch to the OFF position.

Shifting Into NEUTRAL (N)
WARNING!
You or others could be injured or killed if you leave the vehicle unattended with the
transfer case in the NEUTRAL (N) position without first fully engaging the parking
brake. The transfer case NEUTRAL (N) position disengages both the front and rear
driveshafts from the powertrain and will allow the vehicle to move, even if the
transmission is in PARK. The parking brake should always be applied when the
driver is not in the vehicle.
CAUTION!
It is necessary to follow these steps to be certain that the transfer case is fully in
NEUTRAL (N) before recreational towing to prevent damage to internal parts.
Use the following procedure to prepare your vehicle for recreational towing:
1. Bring the vehicle to a complete stop, with the engine running.
2. Press and hold the brake pedal.
3. Shift the transmission into NEUTRAL.
4. If vehicle is equipped with Quadra-Lift air suspension, ensure the vehicle is set to Normal Ride Height.
5. Using a ballpoint pen or similar object, press and hold the recessed transfer case NEUTRAL (N) button (located by the selector switch) for four seconds. The light
behind the N symbol will blink, indicating shift in progress. The light will stop
blinking (stay on solid) when the shift to NEUTRAL (N) is complete. A “FOUR
WHEEL DRIVE SYSTEM IN NEUTRAL” message will display on the Driver
Information Display (DID).
6. After the shift is completed and the NEUTRAL (N) light stays on, release the NEUTRAL (N) button.
7. Shift the transmission into REVERSE.
8. Release the brake pedal for five seconds and ensure that there is no vehicle movement.
9. Press and hold the brake pedal. Shift the transmission back into NEUTRAL
10. Firmly apply the parking brake.
11. With the transmission and transfer case in NEUTRAL, push and hold the ENGINE START/STOP button until the engine turns off.
12. Move the transmission gear selector to PARK. Release the brake pedal.

13. Push the ENGINE STOP/START button twice (without pressing the brake pedal)to turn the ignition switch to the OFF position.
14. Attach the vehicle to the tow vehicle using a suitable tow bar.
15. Release the parking brake.
NOTE:
• Steps 1 through 4 are requirements that must be met before pressing the NEUTRAL (N) button, and must continue to be met until the shift has been
completed. If any of these requirements are not met before pushing the NEUTRAL
(N) button or are no longer met during the shift, then the NEUTRAL (N) indicator
light will flash continuously until all requirements are met or until the NEUTRAL
(N) button is released.
• The ignition switch must be in the ON/RUN position for a shift to take place and for the position indicator lights to be operable. If the ignition switch is not in the
ON/RUN position, the shift will not take place and no position indicator lights will
be on or flashing.
• A flashing NEUTRAL (N) position indicator light indicates that shift requirements have not been met.
• If the vehicle is equipped with Quadra-Lift air suspension, the engine should be started and left running for a minimum of 60 seconds (with all the doors closed)
at least once every 24 hours. This process allows the air suspension to adjust the
vehicle’s ride height to compensate for temperature effects.
Shifting Out Of NEUTRAL (N)
Use the following procedure to prepare your vehicle for normal usage:
1. Bring the vehicle to a complete stop, leaving it connected to the tow vehicle.
2. Firmly apply the parking brake.
3. Start the engine.
4. Press and hold the brake pedal.
5. Shift the transmission into NEUTRAL.
6. Using a ballpoint pen or similar object, push and hold the recessed transfer case
NEUTRAL (N) button (located by the selector switch) for one second.
7. When the NEUTRAL (N) indicator light turns off, release the NEUTRAL (N) button. After the NEUTRAL (N) button has been released, the transfer case will
shift to the position indicated by the selector switch.
8. Shift the transmission into PARK. Turn the engine OFF.

9. Release the brake pedal.
10. Disconnect vehicle from the tow vehicle.
11. Start the engine.
12. Press and hold the brake pedal.
13. Release the parking brake.
14. Shift the transmission into DRIVE, release the brake pedal, and check that thevehicle operates normally.
NOTE:
• Steps 1 through 5 are requirements that must be met prior to pressing the NEUTRAL (N) button, and must continue to be met until the shift has been
completed. If any of these requirements are not met prior to prushing the
NEUTRAL (N) button or are no longer met during the shift, the NEUTRAL (N)
indicator light will flash continuously until all requirements are met or until the
NEUTRAL (N) button is released.
• The ignition switch must be in the ON/RUN position for a shift to take place and for the position indicator lights to be operable. If the ignition switch is not in the
ON/RUN position, the shift will not take place and no position indicator lights will
be on or flashing.
• A flashing NEUTRAL (N) position indicator light indicates that shift requirements have not been met.

FUEL ECONOMY (ECO) MODE
The Fuel Economy (ECO) mode can improve the vehicle's overall fuel economy during
normal driving conditions. Press the “ECO” switch in the center stack of the
instrument panel to activate or disable ECO mode. An amber light indicates when
ECO mode is disengaged.
When the Fuel Economy (ECO) Mode is
engaged, the vehicle control systems will
change the following:
• The transmission will upshift soonerand downshift later.
• The transmission will launch (from a stop) in second gear.
• The torque converter clutch may en- gage at lower engine speeds and re-
main on longer.
• The engine idle speed will be lower.
• The overall driving performance will be more conservative.
• Some ECO mode functions may be temporarily inhibited based on temperature and other factors.
NOTE:
ECO mode is only available in AUTO mode.
Active Noise Cancellation
Your vehicle is equipped with an Active Noise Cancellation System, this system is
designed to address the change in exhaust noise whenever the vehicle is operating in
Fuel Economy Mode (ECO) or 4 cylinder mode.
This system relies on four microphones embedded in the headliner to detect the
exhaust drone and prompt an onboard frequency generator to create counteracting
sound waves through the audio system's speakers and sub-woofer. This helps keep
the vehicle quiet at highway speeds.

Launch Mode — If Equipped
This system maximizes acceleration traction for straight line racing. To use Launch
Mode please follow the steps below:
1. Bring vehicle to complete stop on a level track surface with the engine running.
2. Set the steering wheel for straight ahead driving.
3. Fully press the brake pedal.
4. Press and release the “LAUNCH” Button.
5. Press the accelerator pedal to the floor.
NOTE:
If the cluster launch DID message indicates all conditions are correct for launch and
the throttle is pressed to the floor quickly (within approximately 1/2 second) the
system will hold the engine speed to a preset speed (below the engine rev limiter
speed).
6. Release the brake pedal.
Pressing the launch control button when launch control is active will deactivate
launch control.
NOTE:
• Launch Mode brings the engine to optimum RPM and waits for the driver torelease the brake. Launch Mode then uses engine throttle only to achieve
controlled wheelslip for maximum acceleration through 62 mph (100 km/h).
• Launch Mode can be initiated in any of the Select Trac Modes.
• Launch Mode is not available until the 500 mile (805 km) break-in has been achieved.
