GETTING TO KNOW YOUR VEHICLE 27
To Enter Remote Start Mode
Push and release the Remote Start button on the key
fob twice within five seconds. The parking lights
will flash, vehicle doors will lock, and the horn will
chirp twice (if programmed). Once the vehicle has started,
the engine will run for 15 minutes.
NOTE:
• If your power door locks were unlocked, Remote Start will automatically lock the doors.
• If an engine fault is present or fuel level is low, the vehicle will start and then shut down in 10 seconds.
• The park lamps will turn on and remain on during Remote Start mode.
• For security, power window and power sunroof operation (if equipped) are disabled when the vehicle is in the
Remote Start mode.
• The engine can be started two consecutive times (two 15-minute cycles) with the key fob. However, the ignition
must be placed in the ON/RUN position before you can
repeat the start sequence for a third cycle.
To Exit Remote Start Mode Without Driving The
Vehicle
Push and release the remote start button one time or allow
the engine to run for the entire 15-minute cycle.
NOTE:
To avoid unintentional shutdowns, the system will disable
with a one time push of the remote start button for two
seconds after receiving a valid remote start request.
To Exit Remote Start Mode And Drive The Vehicle
Before the end of the 15-minute cycle, push and release the
unlock button on the key fob to unlock the doors and disarm
the vehicle security alarm system (if equipped). Then, prior
to the end of the 15-minute cycle, cycle the ignition to the
ON/RUN position.
Remote Start Comfort Systems — If Equipped
When Remote Start is activated, the heated steering wheel
and driver heated seat features will automatically turn on in
cold weather. In warm weather, the driver vented seat
feature will automatically turn on when the remote start is
activated. These features will stay on through the duration of
Remote Start or until the ignition switch is placed in the ON/
RUN mode.

166 SAFETY
6. Push the “ESC Off” button located in the lower switchbank below the climate control four times within 20
seconds. The “ESC Off Indicator Light” should turn on
and turn off two times.
7. Rotate the steering wheel back to center and then an addi -
tional slightly more than one-half turn to the right.

8. Turn the ignition to the OFF mode and then back to ON. If the sequence was completed properly, the “ESC Off Indicator
Light” will blink several times to confirm HSA is disabled.

9. Repeat these steps if you want to return this feature to its previous setting.
Traction Control System (TCS)

This system monitors the amount of wheel spin of each of the
driven wheels. If wheel spin is detected, the TCS may apply
brake pressure to the spinning wheel(s) and/or reduce engine
power to provide enhanced acceleration and stability. A
feature of the TCS, Brake Limited Differential (BLD), functions
similar to a limited slip differential and controls the wheel spin
across a driven axle. If one wheel on a driven axle is spinning
faster than the other, the system will apply the brake of the
spinning wheel. This will allow more engine power to be
applied to the wheel that is not spinning. BLD may remain
enabled even if TCS and ESC are in a reduced mode.
Electronic Stability Control (ESC)
This system enhances directional control and stability of the
vehicle under various driving conditions. ESC corrects for
oversteering or understeering of the vehicle by applying the
brake of the appropriate wheel(s) to assist in counteracting
the oversteer or understeer condition. Engine power may
also be reduced to help the vehicle maintain the desired path.
ESC uses sensors in the vehicle to determine the vehicle path
intended by the driver and compares it to the actual path of
the vehicle. When the actual path does not match the
intended path, ESC applies the brake of the appropriate
wheel to assist in counteracting the oversteer or understeer
condition.
• Oversteer — when the vehicle is turning more than appro
-
priate for the steering wheel position.
• Understeer — when the vehicle is turning less than appro -
priate for the steering wheel position.

170 SAFETY
The “ESC OFF Indicator Light” indicates the
customer has elected to have the Electronic Stability
Control (ESC) in a reduced mode.
Electronic Roll Mitigation (ERM)
This system anticipates the potential for wheel lift by moni -
toring the driver’s steering wheel input and the speed of the
vehicle. When ERM determines that the rate of change of the
steering wheel angle and vehicle’s speed are sufficient to
potentially cause wheel lift, it then applies the appropriate
brake and may also reduce engine power to lessen the chance
that wheel lift will occur. ERM can only reduce the chance of
wheel lift occurring during severe or evasive driving maneu-
vers; it cannot prevent wheel lift due to other factors, such as
road conditions, leaving the roadway, or striking objects or
other vehicles.
NOTE:
ERM is disabled anytime the ESC is in “Full Off” mode (if
equipped). Refer to “Electronic Stability Control (ESC)” in
this section for a complete explanation of the available ESC
modes. Trailer Sway Control (TSC)
TSC uses sensors in the vehicle to recognize an excessively
swaying trailer and will take the appropriate actions to
attempt to stop the sway. TSC will become active automati
-
cally once an excessively swaying trailer is recognized.
NOTE:
TSC cannot stop all trailers from swaying. Always use
caution when towing a trailer and follow the trailer tongue
weight recommendations. Refer to “Trailer Towing” in
“Starting And Operating” for further information.WARNING!
Many factors, such as vehicle loading, road conditions
and driving conditions, influence the chance that wheel
lift or rollover may occur. ERM cannot prevent all wheel
lift or roll overs, especially those that involve leaving the
roadway or striking objects or other vehicles. The
capabilities of an ERM-equipped vehicle must never be
exploited in a reckless or dangerous manner which could
jeopardize the user's safety or the safety of others.

212 SAFETY
Enhanced Accident Response System
In the event of an impact, if the communication network
remains intact, and the power remains intact, depending on
the nature of the event, the ORC will determine whether to
have the Enhanced Accident Response System perform the
following functions:
• Cut off fuel to the engine (If Equipped)
• Cut off battery power to the electric motor (If Equipped)
• Flash hazard lights as long as the battery has power
• Turn on the interior lights, which remain on as long as thebattery has power or for 15 minutes from the intervention
of the Enhanced Accident Response System.
• Unlock the power door locks.
Your vehicle may also be designed to perform any of these
other functions in response to the Enhanced Accident
Response System:
• Turn off the Fuel Filter Heater, Turn off the HVAC Blower Motor, Close the HVAC Circulation Door • Cut off battery power to the:
• Engine
• Electric Motor (if equipped)
• Electric power steering
• Brake booster
• Electric park brake
• Automatic transmission gear selector
• Horn
• Front wiper
• Headlamp washer pump
NOTE:
After an accident, remember to cycle the ignition to the STOP
(OFF/LOCK) position and remove the key from the ignition
switch to avoid draining the battery. Carefully check the
vehicle for fuel leaks in the engine compartment and on the
ground near the engine compartment and fuel tank before
resetting the system and starting the engine. If there are no
fuel leaks or damage to the vehicle electrical devices (e.g.
headlights) after an accident, reset the system by following
the procedure described below. If you have any doubt,
contact an authorized dealer.

256 STARTING AND OPERATING
Vehicles With Mechanical Key:
This vehicle is equipped with a Key Ignition Park Interlock
which requires the transmission to be in PARK before the
ignition can be turned to the OFF (key removal) position. The
key can only be removed from the ignition when the ignition
is in the OFF position, and the transmission is locked in
PARK whenever the ignition is in the OFF position. If the
vehicle's battery becomes discharged, the key will be
trapped in the ignition even when the gear selector is in
PARK. Recharge the battery to allow key removal.
NOTE:
If a malfunction occurs, the system will trap the key fob in
the ignition to warn you that this safety feature is inoperable.
The engine can be started and stopped but the key fob cannot
be removed until you obtain service.
Brake/Transmission Shift Interlock System
This vehicle is equipped with a Brake Transmission Shift
Interlock system (BTSI) that holds the transmission gear
selector in PARK unless the brakes are applied. For vehicles
with 8-speed transmission, to shift the transmission out of
PARK, the engine must be running and the brake pedal must
be pressed. The brake pedal must also be pressed to shift
from NEUTRAL into DRIVE or REVERSE when the vehicleis stopped or moving at low speeds. For vehicles with
6-speed transmission, to shift the transmission out of PARK,
the ignition must be in the ON/RUN mode (engine running
or not) and the brake pedal must be pressed.
Six–Speed Automatic Transmission — If Equipped
Chassis Cab models may use the AS66RC transmission
(which is equipped with a Power Take-Off (PTO) access
cover on the side of the transmission case).
The transmission gear position display (located in the instru-
ment cluster) indicates the transmission gear range. The gear
selector is mounted on the right side of the steering column.
You must press the brake pedal to move the gear selector out
of PARK (refer to “Brake/Transmission Shift Interlock
System” in this section). To drive, move the gear selector
from PARK or NEUTRAL to the DRIVE position. Pull the
gear selector toward you when shifting into REVERSE or
PARK, or when shifting out of PARK.
The electronically-controlled transmission provides a precise
shift schedule. The transmission electronics are self-cali
-
brating; therefore, the first few shifts on a new vehicle may
be somewhat abrupt. This is a normal condition, and preci -
sion shifts will develop within a few hundred miles (kilome -
ters).

STARTING AND OPERATING 283
Mobile Mode
To operate the PTO in this mode the vehicle must meet the
following conditions:
• Mobile mode is activated via the menu on the instrumentcluster display.
• (ON/OFF) switch has been activated.
• Transmission must be in PARK or DRIVE.
• Parking brake must not be applied.
• Brake pedal must not be applied.
• No vehicle or brake faults present.
• Vehicle engine must be running.
• PTO must be correctly installed using the vehicle provided circuits.
The customer may choose to use the PTO while the vehicle is
moving. To do so, the PTO function must be activated prior
to taking the vehicle out of PARK. This is accomplished by
activating the upfitter-provided PTO on/off switch. At this
point, the customer may place the vehicle in a forward or
reverse gear and have PTO operation once the vehicle begins
to move. To disengage PTO operation and return to “stan -
dard vehicle operation” simply toggle the on/off switch to
the OFF position. NOTE:
For application specific information with respect to PTO and
pump requirements and additional vehicle information
(wiring schematics, preset idle values, engine speed limits,
and vehicle hardware and software requirements) please
refer to the Body Builders Guide by accessing
rambody-
builder.com and choosing the appropriate links.
POWER STEERING
Hydraulic Power Steering
The standard power steering system will give you good
vehicle response and increased ease of maneuverability in
tight spaces. The system will provide mechanical steering
capability if power assist is lost.
If for some reason the power assist is interrupted, it will still
be possible to steer your vehicle. Under these conditions, you
will observe a substantial increase in steering effort, espe -
cially at very low vehicle speeds and during parking maneu-
vers.
