ESP Partial Off
This mode is entered by momentarily depressing the
9ESP OFFº switch. When in9Partial Off9mode, the TCS
portion of ESP, except for the ªlimited slipº feature
described in the TCS section, has been disabled and the
9ESP/TCS Indicator Light9will be illuminated. All other
stability features of ESP function normally. This mode is
intended to be used if the vehicle is in deep snow, sand,
or gravel conditions and more wheel spin than ESP
would normally allow is required to gain traction. To
turn ESP on again, momentarily depress the9ESP OFFº
switch. This will restore the normal ªESP Onº mode of
operation.
NOTE:To improve the vehicle's traction when driving
with snow chains, or starting off in deep snow, sand or
gravel, it may be desirable to switch to the ªPartial Offº
mode by pressing the ESP switch. Once the situation
requiring ESP to be switched to the ªPartial Offº mode isovercome, turn ESP back on by momentarily depressing
the ªESP Control Switchº. This may be done while the
vehicle is in motion.
WARNING!
In the Partial Off mode, the engine torque reduction
and stability features are desensitized. Therefore, the
enhanced vehicle stability offered by ESP is
unavailable.
All 4WD vehicles in Auto and 4HI Modes can also
choose the following ESP operating mode. This is
the only ESP operating mode in 4LO:
Full Off
This mode is intended for off-road use when ESP stability
features could inhibit vehicle maneuverability due to trail
conditions. This mode is entered by depressing and

These cautions apply to all chain traction devices, includ-
ing link and cable (radial) chains.
Tire chain use is permitted only on the rear tires of 4X2
model trucks.
NOTE:The use of class ªSº chains is permitted on 1500
model trucks with P245/70R17 tires only.
NOTE:The use of class ªUº chains is permitted on the
front and rear of 4X4, 2500 model trucks with LT245/
70R17E tires.
NOTE:The use of class ªUº chains is permitted on the
front and rear of 4X4, 3500 model trucks with Dual Rear
Wheels and LT235/80R17E tires.
NOTE:On 4X2 2500/3500 model trucks, class ªUº snow
chains are permitted on the rear wheels only of vehicles
equipped with LT245/70R17, LT265/70R17, and LT235/
80R17 size tires.NOTE:On 4x4 2500/3500 SRW (Single Rear Wheel)
model trucks, class ªUº snow chains are permitted on the
rear wheels only of vehicles equipped with LT265/
70R17E.
CAUTION!
Do not use tire chains on 4x4 model trucks equipped
with P265/70R17, LT275/70R17, P275/60R20, tires.
There may not be adequate clearance for the chains
and you are risking structural or body damage to
your vehicle. Do not use tire chains on the 4X2 front
wheels of 2500/3500 SRW (Single Rear Wheels)
equipped with LT245/70R17, LT265/70R17 LT235/
80R17 tires, or 4X4 front wheels of Ram Trucks
equipped with LT265/70R17E. There may not be
adequate clearance for the chains and you are risking
structural or body damage to your vehicle.
358 STARTING AND OPERATING

the ignition key is cycled, this sequence will repeat,
providing the system fault still exists. A system fault can
occur by any of the following scenarios:
1. Signal interference due to electronic devices or driving
next to facilities emitting the same Radio Frequencies as
the TPM sensors.
2. Installing aftermarket window tinting that affects ra-
dio wave signals.
3. Accumulation of snow or ice around the wheels or
wheel housings.
4. Using tire chains on the vehicle.
5. Using wheels/tires not equipped with TPM sensors.
6. Loss of communication with the trigger modules or
tire pressure monitoring sensors.
NOTE: Your vehicle is equipped with a non-matching
full size spare wheel and tire assembly.1. This spare tire does not have a tire pressure monitor-
ing sensor. Therefore, the TPMS will not monitor the tire
pressure in the spare tire.
2. If you install the full size spare tire in place of a road
tire that has a pressure below the low-pressure warning
limit, upon the next ignition key cycle, a chime will
sound and the TPM Telltale Light will still turn ON due
to the low tire.
3. However, after driving the vehicle for up to 10 min-
utes above 15 mph (25 km/h), the TPM Telltale Light will
flash on and off for 75 seconds and then remain on solid.
4. For each subsequent ignition key cycle, a chime will
sound and the TPM 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 full size spare tire,
the TPMS will update automatically and the TPM Telltale
