SAFETY FEATURES
Anti-Lock Brake System (ABS)
The Anti-Lock Brake System (ABS) provides increased
vehicle stability and brake performance under most braking
conditions. The system automatically prevents wheel lock,
and enhances vehicle control during braking.
The ABS performs a self-check cycle to ensure that the ABS
is working properly each time the vehicle is started and
driven. During this self-check, you may hear a slight clicking
sound as well as some related motor noises.
ABS is activated during braking when the system detects one
or more wheels begin to lock. Road conditions such as ice,
snow, gravel, bumps, railroad tracks, loose debris, or panic
stops may increase the likelihood of ABS activation(s).You also may experience the following when ABS activates:
• The ABS motor noise (it may continue to run for a short
time after the stop).
• The clicking sound of solenoid valves.
• Brake pedal pulsations.
• A slight drop of the brake pedal at the end of the stop.
These are all normal characteristics of ABS.
WARNING!
• The ABS contains sophisticated electronic equipment that may be susceptible to interference caused by
improperly installed or high output radio transmitting
equipment. This interference can cause possible loss of
anti-lock braking capability. Installation of such equip -
ment should be performed by qualified professionals.
• Pumping of the Anti-Lock Brakes will diminish their effectiveness and may lead to a collision. Pumping
makes the stopping distance longer. Just press firmly
on your brake pedal when you need to slow down or
stop.

164 SAFETY
Hill Start Assist (HSA)
The HSA system is designed to mitigate roll back from a
complete stop while on an incline. If the driver releases the
brake while stopped on an incline, HSA will continue to hold
the brake pressure for a short period. If the driver does not
apply the throttle before this time expires, the system will
release brake pressure and the vehicle will roll down the hill
as normal.
The following conditions must be met in order for HSA to
activate:
• The feature must be enabled.
• The vehicle must be stopped.
• Park brake must be off.
• Driver door must be closed.
• The vehicle must be on a sufficient grade.
• The gear selection must match vehicle uphill direction (i.e.,vehicle facing uphill is in forward gear; vehicle backing
uphill is in REVERSE gear). • HSA will work in REVERSE gear and all forward gears.
The system will not activate if the transmission is in PARK
or NEUTRAL. For vehicles equipped with a manual trans -
mission, if the clutch is pressed, HSA will remain active.
WARNING!
There may be situations where the Hill Start Assist
(HSA) will not activate and slight rolling may occur,
such as on minor hills or with a loaded vehicle, or while
pulling a trailer. HSA is not a substitute for active
driving involvement. It is always the driver’s
responsibility to be attentive to distance to other
vehicles, people, and objects, and most importantly
brake operation to ensure safe operation of the vehicle
under all road conditions. Your complete attention is
always required while driving to maintain safe control of
your vehicle. Failure to follow these warnings can result
in a collision or serious personal injury.

SAFETY 169
ESC Activation/Malfunction Indicator Light And ESC
OFF Indicator Light The “ESC Activation/Malfunction Indicator Light”
in the instrument cluster will come on when the igni -
tion is turned to the ON mode. It should go out with
the engine running. If the “ESC Activation/Malfunction
Indicator Light” comes on continuously with the engine
running, a malfunction has been detected in the ESC system. If this light remains on after several ignition cycles, and the
vehicle has been driven several miles (kilometers) at speeds
greater than 30 mph (48 km/h), see an authorized dealer as
soon as possible to have the problem diagnosed and
corrected.
The “ESC Activation/Malfunction Indicator Light” (located
in the instrument cluster) starts to flash as soon as the tires
lose traction and the ESC system becomes active. The “ESC
Activation/Malfunction Indicator Light” also flashes when
TCS is active. If the “ESC Activation/Malfunction Indicator
Light” begins to flash during acceleration, ease up on the
accelerator and apply as little throttle as possible. Be sure to
adapt your speed and driving to the prevailing road condi
-
tions.
NOTE:
• The “ESC Activation/Malfunction Indicator Light” and the “ESC OFF Indicator Light” come on momentarily each
time the ignition is turned ON.
• Each time the ignition is turned ON, the ESC system will be on even if it was turned off previously.
• The ESC system will make buzzing or clicking sounds when it is active. This is normal; the sounds will stop when
ESC becomes inactive following the maneuver that caused
the ESC activation.
WARNING!
• In the ESC “Full Off” mode, the engine torque reduc -
tion and stability features are disabled. Therefore,
enhanced vehicle stability offered by the ESC system is
unavailable. In an emergency evasive maneuver, the
ESC system will not engage to assist in maintaining
stability. ESC “Full Off” mode is intended for
off-highway or off-road use only.
• The Electronic Stability Control (ESC) cannot prevent the natural laws of physics from acting on the vehicle,
nor can it increase the traction afforded by prevailing
road conditions. ESC cannot prevent all accidents,
including those resulting from excessive speed in
turns, driving on very slippery surfaces, or hydro -
planing. ESC also cannot prevent collisions.

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.

Only
AutoPark is a supplemental feature to assist in placing the
vehicle in PARK should the situations on the following
pages occur. It is a back up system and should not be relied
upon as the primary method by which the driver shifts the
vehicle into PARK.
The conditions under which AutoPark will engage are
outlined on the following pages.
WARNING!
• Driver inattention could lead to failure to place the vehicle in PARK. ALWAYS DO A VISUAL CHECK
that your vehicle is in PARK by verifying that a solid
(not blinking) “P” is indicated in the Instrument
Cluster Display and near the gear selector. If the "P"
indicator is blinking, your vehicle is not in PARK. As
an added precaution, always apply the parking brake
when exiting the vehicle.
• AutoPark is a supplemental feature. It is not designed to replace the need to shift your vehicle into PARK. It is
a back up system and should not be relied upon as the
primary method by which the driver shifts the vehicle
into PARK.

AUTOMATIC TRANSMISSION
WARNING!
• It is dangerous to shift out of PARK or NEUTRAL if the engine speed is higher than idle speed. If your foot is
not firmly pressing the brake pedal, the vehicle could
accelerate quickly forward or in reverse. You could lose
control of the vehicle and hit someone or something.
Only shift into gear when the engine is idling normally
and your foot is firmly pressing the brake pedal.
• The transmission may not engage PARK if the vehicle is moving. Always bring the vehicle to a complete stop
before shifting to PARK, and verify that the transmis -
sion gear position indicator solidly indicates PARK (P)
without blinking. Ensure that the vehicle is completely
stopped, and the PARK position is properly indicated,
before exiting the vehicle.• Unintended movement of a vehicle could injure those in or near the vehicle. As with all vehicles, you should
never exit a vehicle while the engine is running. Before
exiting a vehicle, always come to a complete stop, then
apply the parking brake, shift the transmission into
PARK, turn the engine OFF, and remove the key fob.
When the ignition is in the LOCK/OFF (key removal)
position, (or, with Keyless Enter-N-Go, when the igni -
tion is in the OFF mode) the transmission is locked in
PARK, securing the vehicle against unwanted move -
ment.
• When leaving the vehicle, always make sure the igni -
tion is in the OFF mode, remove the key fob from the
vehicle, and lock the vehicle.
• Never use the PARK position as a substitute for the parking brake. Always apply the parking brake fully
when exiting the vehicle to guard against vehicle move -
ment and possible injury or damage.
• Your vehicle could move and injure you and others if it is not in PARK. Check by trying to move the gear
selector out of PARK with the brake pedal released.
Make sure the transmission is in PARK before exiting
the vehicle.
WARNING! (Continued)

STARTING AND OPERATING 255
NOTE:
You must press and hold the brake pedal while shifting out
of PARK.
Ignition Park Interlock
Vehicles With Pushbutton Start:
This vehicle is equipped with an Ignition Park Interlock
which requires the transmission to be in PARK before the
ignition can be turned to the OFF mode. This helps the driver
avoid inadvertently leaving the vehicle without placing the
transmission in PARK. This system also locks the transmis-
sion in PARK whenever the ignition is in the OFF mode.
NOTE:
The transmission is NOT locked in PARK when the ignition
is in the ACC mode (even though the engine will be off).
Ensure that the transmission is in PARK, and the ignition is
OFF (not in ACC mode) before exiting the vehicle.
• Never leave children alone in a vehicle, or with access
to an unlocked vehicle. Allowing children to be in a
vehicle unattended is dangerous for a number of
reasons. A child or others could be seriously or fatally
injured. Children should be warned not to touch the
parking brake, brake pedal or the transmission gear
selector.
• Do not leave the key fob in or near the vehicle (or in a location accessible to children), and do not leave the
ignition (in a vehicle equipped with Keyless
Enter-N-Go) in the ACC or ON/RUN mode. A child
could operate power windows, other controls, or move
the vehicle.
CAUTION!
• Shift into or out of PARK or REVERSE only after the vehicle has come to a complete stop.
• Do not shift between PARK, REVERSE, NEUTRAL, or DRIVE when the engine is above idle speed.
• Before shifting into any gear, make sure your foot is firmly pressing the brake pedal.
WARNING! (Continued)

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).
