Push-Button Ignition and Smart Key Fob

Depending on the body builder and dealer, the push-button ignition may be programmed with a 'Welcome Feature'. This allows the push-button ignition to illuminate—even in the OFF position—when the smart key fob is within approximately 4 to 5 ft (1 to 2 m).

The push-button ignition switch has four positions. See Fig..

Blue illumination notifies the driver that the engine is running.

Starting the Engine

To start the engine, depress the brake pedal and press the START/STOP ENGINE button with the transmission shifter in neutral (N). If the wait to start lamp is active, a second button press is required to start the engine.

If the START/STOP ENGINE button is pressed without depressing the brake pedal, the engine will not start and the button will change as follows: OFF → ACC → ON → OFF

Alternate Starting Method

The primary starting sequence will not operate as previously described when any of the following conditions are true:

• The smart key fob battery is dead.

• The smart key fob is not working correctly.

• The primary brake air tank is empty.

During these conditions, an alternate starting method is required. Use the lock button end of the smart key fob to contact the START/STOP ENGINE button directly. See Fig..

Note: Place the lock button end of the smart key fob directly on the START/STOP ENGINE button.

Fig. 2, Alternate Starting Method

One press of the START/STOP ENGINE button with the smart key fob will change as follows: OFF → ACC → ON → OFF

The engine will start when the smart key fob is pressed and held directly on the START/STOP ENGINE button for longer than 1 second.

Accessory (ACC)

To activate the accessory position, press the START/STOP ENGINE button while the ignition is in the OFF position without depressing the brake pedal. The ACC indicator remains illuminated until the ignition switch moves to the next position.

The headlights (low beams), brake lights, fog lights, dome lights, clearance lights, turn signals, hazard warning lights, and parking lights operate in the ACC position.

ON

To activate the ON position do one of the following:

• Press and hold the START/STOP ENGINE button for more than 1 second while the ignition is in the OFF position without depressing the brake pedal.

• Press the START/STOP ENGINE button while the ignition is in the ACC position without depressing the brake pedal.

The ON indicator remains illuminated until the ignition switch moves to the next position. All electrical systems are operable in the ON position. The warning lights and the buzzer for low air pressure and low oil pressure operate until minimum pressures are built up.

OFF

To turn off the engine or the vehicle power, press the START/STOP ENGINE button when the vehicle is not in motion. The OFF indicator illuminates for 5 seconds, then deactivates.

All of the components (headlights [low beams], brake lights, fog lights, etc.) that are operable in the ACC position are operable in the OFF position.

Smart Key Fob Control Buttons

The following is a description of the smart key fob control buttons. For an example of the control buttons, see Fig..

• One press of the front entry door lock button commands the system to lock the front entry door.

• One press of the front entry door unlock button commands the system to unlock the front entry door.

• One press of the cargo doors lock button commands the system to lock the cargo doors.

• One press of the cargo doors unlock button commands the system to unlock the cargo doors.

Note: The function of the smart key fob control buttons can be different for each bodybuilder. The description of the smart key fob control buttons is for a typical fob.

Smart Key Fob Range

The operational range of the smart key fob is affected by the location of the key fob and any metal structure that may prohibit the signal. The smart key fob operates up to the distances shown below, when measured from the center of a given location outward without any object between the smart key fob and the vehicle.

• in front of the vehicle–125 ft (38 m)

• either side of the vehicle–75 ft (23 m)

• behind the vehicle–10 ft (3 m)

Smart Key Fob Interference

Operational interference of the smart key fob can occur when used near radio transmitting devices such as a radio station, airport, mobile two-way radio system, cell phone or smart phone, or when another vehicle's smart key fob is being operated. Extreme temperatures, either low or high, can also cause operational interference.

If the smart key fob is in close proximity to a cell phone or smart phone, such as a pants or jacket pocket, the signal from the smart key fob could be blocked. This is especially important when the phone is active—making or receiving calls, text messaging, and sending or receiving email. Keep the two devices in separate locations to avoid any interference.
