the transmission must be in neutral with the vehicle
parking brakes set and the engine in idle or fast-idle
mode.
California Engine Idle Limiting
In order to meet the California Air Resourses Board
(CARB) engine idle limiting standard, an engine idle
shutdown feature has been included in engine con-
trol strategy. When the CARB engine idle limiting fea-
ture is enabled, the engine will generally shut down
after five minutes of continuous idling when the
transmission is in neutral or park, and the parking
brake is set, or after fifteen minutes when the trans-
mission is in neutral or park, and the parking brake is
not set.
Activating or momentarily changing the position of
the service-brake pedal, the clutch pedal, stop-
engine override switch, the accelerator pedal, or
parking brake, during the final 30 seconds before a
shutdown would otherwise occur, will prevent the en-
gine from shutting down, and will reset the shutdown
timer. After an automatic shutdown, the engine may
be restarted and operated normally.
The automatic shutdown feature is generally disabled
on engines certified by the U.S. EPA for use outside
California, but is required to be enabled for all
California-certified engines (with the exception of en-
gines used in specific vehicle types that the state of
California has determined to be exempt from the idle
shutdown requirement). Owners that wish to have
the shutdown feature disabled should consult with
California authorities to determine if their vehicle
qualifies for the exemption.
Cruise Control
IMPORTANT: For vehicles with Eaton VORAD
Collision Warning System (CWS) with Smart-
Cruise, see the "Collision Warning System" in
Chapter 4 of this manual, before operating
cruise control.
The cruise control is activated by the SPD CNTL (on/
off) and RSM/ACC–SET/CST switches on the dash
(
Fig. 10.3), or by optional PAUSE, RESUME, and
SET buttons on the transmission shift knob
(
Fig. 10.4). The minimum speed at which cruise con-
trol can be used is 30 mph (48 km/h). The minimum
and maximum speed cruise control set limits can be
programmed, by authorized personnel, into the en-
gine electronics.
WARNING
Do not use the cruise control system when driv-
ing conditions do not permit maintaining a con-
stant speed, such as in heavy traffic or on roads
that are winding, icy, snow-covered, slippery, or
roads with a loose driving surface. Failure to fol-
low this precaution could cause a collision or
loss of vehicle control, possibly resulting in per-
sonal injury or property damage.
NOTICE
Do not attempt to shift gears without using the
clutch pedal when the cruise control is engaged.
Failure to follow this precaution will result in a
temporarily uncontrolled increase in engine
