Partial Off
The “Partial Off” mode is intended for times when a more
spirited driving experience is desired. This mode may
modify TCS and ESC thresholds for activation, which
allows for more wheel spin than normally allowed. This
mode may be useful if the vehicle becomes stuck.
To enter the “Partial Off” mode, momentarily push the
“ESC Off” switch and the “ESC Off Indicator Light” will
illuminate. To turn the ESC on again, momentarily push
the “ESC Off” switch and the “ESC Off Indicator Light”
will turn off.
NOTE:For vehicles with multiple partial ESC modes a
momentary button push will toggle the ESC mode. Mul-
tiple momentary button pushed may be required to return
to ESC On.
NOTE:
• When in “Partial Off” mode, the TCS functionality of
ESC, (except for the limited slip feature described in the
TCS section), has been disabled and the “ESC Off
Indicator Light” will be illuminated. When in “Partial
Off” mode, the engine power reduction feature of TCS is
disabled, and the enhanced vehicle stability offered by
the ESC system is reduced. •
Trailer Sway control (TSC) is disabled when the ESC
system is in the “Partial Off” mode.
Full Off – If Equipped
This mode is intended for off-highway or off-road use only
and should not be used on any public roadways. In this
mode, TCS and ESC features are turned OFF. To enter the
“Full Off” mode, push and hold the “ESC Off” switch for
five seconds while the vehicle is stopped with the engine
running. After five seconds, a chime will sound, the “ESC
Off Indicator Light” will illuminate, and the “ESC OFF”
message will display in the instrument cluster. To turn ESC
on again, momentarily push the “ESC Off” switch.
NOTE: System may switch from ESC “Full Off” to “Partial
Off” mode when vehicle exceeds a predetermined speed.
When the vehicle speed slows below the predetermined
speed the system will return to ESC “Full Off”.
ESC modes may also be affected by drive modes (if
equipped).
502 STARTING AND OPERATING
Dual Rear Wheels — If Equipped
The tires used on dual wheel assemblies should be
matched for wear to prevent overloading one tire in a set.
To check if tires are even, lay a straight edge across all four
tires. The straight edge should touch all the tires.NOTE:
If your vehicle is equipped with a Tire Pressure
Information System (TPIS):
• The Tire Pressure Information System (TPIS) uses
unique sensors in the inner rear wheels to help identify
them from the outer rear wheels, because of this, the
inner and outer wheel locations can’t be switched.
• After a tire rotation is completed, as shown below, the
system can auto learn the locations of each sensor ID.
Auto learning/localization occurs when the vehicle ig-
nition status is changed from Off to On and speeds of
greater than 5 mph (8km/h) are obtained and remain
over 5 mph (8km/h) for at about a 15 minute period.
You may need to drive for 20 minutes to account slower
speeds and stops.
• If the tires are rotated incorrectly, The auto localization
of the TPIS sensors will fail to locate correctly resulting
in incorrect locations for the pressure values displayed
in the instrument cluster.
Tire Rotation
532 STARTING AND OPERATING
NOTE:It is particularly important for you to check the tire
pressure in all of the tires on your vehicle monthly and to
maintain the proper pressure.
The TPMS consists of the following components:
• Receiver module
• Four TPM sensors
• Various TPMS messages, which display in the instru-
ment cluster
• TPM Telltale Light
Tire Pressure Monitoring Low Pressure Warnings
The “Tire Pressure Monitoring Telltale Light” will
illuminate in the instrument cluster and a chime
will sound when tire pressure is low in one or more of the
four active road tires. In addition, the instrument cluster
will display a “LOW TIRE” message and a graphic show-
ing the pressure values of each tire with the low tire
pressure values in a different color. An Inflate to XX
message will also be displayed. Should this occur, you should stop as soon as possible and
inflate the tires with a low pressure condition (those in a
different color in the instrument cluster graphic) to the
vehicle’s recommended cold placard pressure inflation
value as shown in the
Inflate to XXmessage. Once the
system receives the updated tire pressures, the system will
automatically update, the graphic display in the instru-
ment cluster will return to it’s original color, and the “Tire
Pressure Monitoring Telltale Light” will turn off. The
vehicle may need to be driven for up to 20 minutes above
15 mph (24 km/h) in order for the TPMS to receive this
information.
“LOW TIRE PRESSURE” Message

STARTING AND OPERATING 537
Service TPMS Warning
If a system fault is detected, the “Tire Pressure Monitoring
Telltale Light” will flash on and off for 75 seconds and then
remain on solid. The system fault will also sound a chime.
In addition, the instrument cluster will display aSERVICE
TPM SYSTEM message for a minimum of five seconds and
then display dashes (- -) in place of the pressure value to
indicate which sensor is not being received.
If the ignition switch is cycled, this sequence will repeat,
providing the system fault still exists. If the system fault no
longer exists, the “Tire Pressure Monitoring Telltale Light”
will no longer flash, and the SERVICE TPM SYSTEMmessage will no longer display, and a pressure value will
display in place of the dashes. A system fault can occur due
to any of the following:
•
Signal interference due to electronic devices or driving
next to facilities emitting the same radio frequencies as
the TPM sensors.
• Installing aftermarket window tinting that contains ma-
terials that may block radio wave signals.
• Accumulation of snow or ice around the wheels or
wheel housings.
• Using tire chains on the vehicle.
• Using wheels/tires not equipped with TPM sensors.
Vehicles With Non Matching Full Size Spare Or Compact
Spare
• The non matching full size spare or compact spare tire
does not have a TPM sensor. Therefore, the TPMS will
not monitor the pressure in the non matching full size
spare or compact spare tire.
• If you install the non matching full size spare or compact
spare tire in place of a road tire that has a pressure below
the low-pressure warning limit, upon the next ignition
Tire Pressure Monitor Display
538 STARTING AND OPERATING
switch cycle, the TPM Telltale Light and a “LOW TIRE”
message will remain ON and a chime will sound. In
addition, the graphic in the instrument cluster will still
display a pressure value in a different color.
• For each subsequent ignition switch cycle, a chime will
sound, the TPM Telltale Light will flash on and off for 75
seconds and then remain on solid, and the instrument
cluster will display a SERVICE TPM SYSTEM message
for a minimum of five seconds and then display dashes
(- -) in place of the pressure value.
• Once you repair or replace the original road tire and
reinstall it on the vehicle in place of the non matching
full size spare or compact spare, the TPMS will update
automatically. In addition, the TPM Telltale Light will
turn OFF and the graphic in the instrument cluster will
display a new pressure value instead of dashes (- -). The
vehicle may need to be driven for up to 20 minutes
above 15 mph (24 km/h) in order for the TPMS to
receive this information.
Tire Pressure Information System (TPIS) 3500
Series Trucks
Your vehicle may be equipped with a Tire Pressure Infor-
mation System (TPIS). The Tire Pressure Information System (TPIS) uses wireless
technology with wheel rim mounted electronic sensors to
transmit tire pressure levels. Sensors mounted to each
wheel as part of the valve stem transmit tire pressure
readings to the receiver module.
NOTE:
It is particularly important for you to check the tire
pressure in all of the tires on your vehicle monthly and to
maintain the proper pressure.
The TPIS consists of the following components:
• Receiver module
• Four TPM sensors (Single Rear Wheel (SRW) applica-
tions)
• Six TPM sensors (Dual Rear Wheel (DRW) applications)
• Pressure display in the instrument cluster
The TPIS system will display all four (Single Rear Wheel
(SRW) applications) or six (Dual Rear Wheel (DRW) appli-
cations) tire pressure values in the instrument cluster
display.
