Partial Off – Two Wheel Drive Vehicles And Four Wheel
Drive Vehicles In 2WD And 4WD High Range
The “Partial Off” mode is intended for driving in deep
snow, sand, or gravel. This mode raises the threshold for
TCS and ESC activation, which allows for more wheel spin
than what ESC normally allows.
To enter the “Partial Off” mode, momentarily push the
“ESC Off” button and the ESC Off indicator light will
illuminate. To turn the ESC on again, momentarily pushthe ESC OFF button and the ESC Off indicator light will
turn off. This will restore the normal “ESC On” mode of
operation.
NOTE:
To improve the vehicle’s traction when driving
with snow chains, or when starting off in deep snow, sand,
or gravel, it may be desirable to switch to the “Partial Off”
mode by momentarily pushing the “ESC Off” button. Once
the situation requiring “Partial Off” mode is overcome,
turn ESC back on by momentarily pushing the “ESC Off”
button. This may be done while the vehicle is in motion.
WARNING!
• 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.

174 SAFETY
•Jamming due to electronic devices or driving next to
facilities emitting the same radio frequencies as the
TPMS sensors.
• Installing some form of aftermarket window tinting that
affects radio wave signals.
• Lots of snow or ice around the wheels or wheel hous-
ings.
• Using tire chains on the vehicle.
• Using wheels/tires not equipped with TPMS sensors.
Vehicles With Compact Spare or non-Matching Full Size
Spare
1. The compact spare tire or non-matching full size spare tire does not have a tire pressure monitoring sensor.
Therefore, the TPMS will not monitor the pressure in the
spare tire.
2. If you install the compact or non-matching full size spare tire in place of a road tire that has a pressure below
the low-pressure warning limit, a chime will sound and
the “TPMS Telltale Light” and “LOW TIRE PRESSURE”
and Inflate to XX messages will turn on upon the next
ignition cycle. 3. After driving the vehicle for up to 20 minutes above
15.5 mph (25 km/h), the “TPMS Telltale Light” will flash
on and off for 75 seconds and then remain on solid.
4. For each subsequent ignition cycle, a chime will sound and the “TPMS Telltale Light” will flash on and off for
75 seconds and then remain on solid.
5. Once you repair or replace the original road tire and reinstall it on the vehicle in place of the compact spare or
non-matching full size spare, the TPMS will update
automatically and the “TPMS Telltale Light” will turn
off, as long as no tire pressure is below the low-pressure
warning limit in any of the four active road tires. The
vehicle may need to be driven for up to 20 minutes
above 15.5 mph (25 km/h) in order for the TPMS to
receive this information.
Tire Pressure Monitor System Operation
The Tire Pressure Monitor System (TPMS) uses wireless
technology with wheel rim mounted electronic sensors to
monitor tire pressure levels. Sensors, mounted to each
wheel as part of the valve stem, transmit tire pressure
readings to the receiver module.

SAFETY 199
NOTE:When filling warm tires, the tire pressure may need
to be increased up to an additional 4 psi (30 kPa) above the
recommended cold placard pressure in order to turn the
Tire Pressure Monitoring Telltale Light off.
The vehicle may need to be driven for up to 20 minutes
above 15.5 mph (25 km/h) in order for the TPMS to receive
this information.
Service TPMS Warning
When a system fault is detected, the “Tire Pressure Moni-
toring 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 a
SERVICE 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 key 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 SYSTEM”
message 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: •
Jamming due to electronic devices or driving next to
facilities emitting the same radio frequencies as the
TPMS sensors.
• Installing some form of aftermarket window tinting that
affects radio wave signals.
• Lots of snow or ice around the wheels or wheel hous-
ings.
• Using tire chains on the vehicle.
• Using wheels/tires not equipped with TPMS sensors.
Vehicles With Matching Full-Size Spare
1. The matching full size spare wheel and tire assembly has a tire pressure monitoring sensor that can be moni-
tored by the TPMS.
2. If you install the full size spare in place of a road tire that has a pressure below the low-pressure warning limit, a
chime will sound and the “TPMS Telltale Light” will
turn on upon the next ignition key cycle. In addition, the
instrument cluster will display a Tire Low message, an
Inflate to XX message and a graphic showing the low
tire pressure value in a different color.

SAFETY 201
Dark Vapor Or Black Satin Chrome Wheels
CAUTION!
If your vehicle is equipped with Dark Vapor or Black
Satin Chrome wheels DO NOT USE wheel cleaners,
abrasives or polishing compounds. They will perma-
nently damage this finish and such damage is not
covered by the New Vehicle Limited Warranty. USE
ONLY MILD SOAP AND WATER WITH A SOFT
CLOTH. Used on a regular basis; this is all that is
required to maintain this finish.
Tire Chains (Traction Devices)
Use of traction devices require sufficient tire-to-body clear-
ance. Follow these recommendations to guard against
damage.
•Traction device must be of proper size for the tire, as
recommended by the traction device manufacturer.
• Install on front tires only.
• Due to limited clearance, the following traction devices
are recommended: All Models:
•
The use of 7mm tire chains is permitted with the use of
215/65R16 and 215/60R17 tires only. Front tires ONLY.
• Original equipment 215/65R17 (trailhawk tires), 225/
55R18 tire sizes are NOT chainable.
CAUTION!
• Use on front tires ONLY.
• Damage may result if tire chains or traction devices
are used with original equipment size tires.
WARNING!
Using tires of different size and type (M+S, Snow)
between front and rear axles can cause unpredictable
handling. You could lose control and have a collision.
