snow chains JEEP WRANGLER 2017 JK / 3.G Owners Manual

The ESC system has three available operating modes in 4H
range. The system has one operating mode in 4L range.
Two-wheel drive vehicles and four-wheel drive vehicles in
2H range have two operating modes.
4H Range (4WD Models)
ESC On
This is the normal operating mode for ESC in 4H range.
ESC Partial Off
This mode is entered by momentarily pushing the ESC
OFF switch. When inESC Partial Offmode, the TCS
portion 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.
This mode is intended to be used if the vehicle is in deep
snow, sand, or gravel conditions and more wheel spin than
ESC would normally allow is required to gain traction. To
turn ESC on again, momentarily push the ESC OFF switch.
This will restore the normal “ESC On” 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 ESC Partial Off
mode by pushing the ESC OFF switch. Once the situation
requiring ESC to be switched to the ESC Partial Offmode
is overcome, turn ESC back on by momentarily pushing the
ESC OFF switch. This may be done while the vehicle is in
motion.
WARNING!
• When in ESC Partial Off mode, the TCS function-
ality 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 ESC Partial Off mode, the engine power
reduction feature of TCS is disabled, and the en-
hanced vehicle stability offered by the ESC system is
reduced.
• Trailer Sway control (TSC) is disabled when the ESC
system is in the ESC Partial Off mode.
220 SAFETY

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 ESC Partial Off
mode by pushing the ESC Full Offswitch. Once the
situation requiring ESC to be switched to the ESC Partial
Off mode is overcome, turn ESC back on by momentarily
pushing the ESC Full Off switch. This may be done while
the vehicle is in motion.
The ESC will restore to normal ESC On mode after each
key on.
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 Offmode. 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
ignition 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 your authorized
dealer as soon as possible to have the problem diagnosed and
corrected.
The “ESC Activation/Malfunction Indicator Light” (lo-
cated 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 conditions.

2. Installing some form of aftermarket window tinting thataffects radio wave signals.
3. Lots of snow or ice around the wheels or wheel hous- ings.
4. Using tire chains on the vehicle.
5. Using wheels/tires not equipped with TPM sensors.
Vehicles not equipped with instrument cluster display will
inform the driver which tire(s) are low but not provide
actual tire pressure. The low tire ISO telltale will illuminate
along with “LoTIrE” message displayed in the ODO and
then it will scroll to which tire location is lower than the
Placard Value.
Tire location will be displayed as follows:
LF = LeftFront
rF = right Front
Lr = Leftrear
rr = right rear NOTE:
•
If your vehicle is equipped with a matching full-size
spare wheel and tire assembly, it has a tire pressure
monitoring sensor, and can be monitored by the Tire
Pressure Monitoring System (TPMS) when swapped
with a low pressure road tire. In the event that the
matching full-size spare tire is swapped with a low
pressure road tire, the next ignition key cycle will still
show the “Tire Pressure Monitoring Telltale Light” to be
ON, and a chime to sound. Driving the vehicle for up to
20 minutes above 15 mph (24 km/h) will turn OFF the
“Tire Pressure Monitoring Telltale Light” as long as none
of the road tires are below the low pressure warning
threshold.
• If your vehicle is not equipped with a matching full-size
spare wheel and tire assembly, it does not have a tire
pressure monitoring sensor in the spare tire. The TPMS
will not be able to monitor the tire pressure. If you install
the 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 “Tire
Pressure Monitoring Telltale Light” will turn ON. After
driving the vehicle for up to 20 minutes above 15 mph
(24 km/h), the “Tire Pressure Monitoring Telltale Light”
230 SAFETY

Should a low tire condition occur on any of the four active
road tire(s), you should stop as soon as possible, and inflate
the low tire(s) that is highlighted or shown in a different
color on the graphic display to the vehicle’s recommended
cold tire pressure inflation value shown in the “Inflate to
XX” message. The system will automatically update, the
graphic display of the pressure value(s) will no longer be
highlighted or shown in a different color and the Tire
Pressure Monitoring Telltale Light will extinguish once the
updated tire pressure(s) have been received.
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 mph (24 km/h) to receive this information.
Service TPM System Warning
The “Tire Pressure Monitoring Telltale Light” will flash on
and off for 75 seconds, and remain on solid when a system
fault is detected. The system fault will also sound a chime.
The instrument cluster will display a “SERVICE TPM
SYSTEM” message for a minimum of five seconds. This
message is then followed by a graphic display, with “- -“ in place of the pressure value(s), indicating which Tire Pres-
sure Monitoring Sensor(s) 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, the
SERVICE TPM SYSTEM message
will not be present, and a pressure value will be displayed
instead of dashes. A system fault can occur by any of the
following:
• Jamming due to electronic devices or driving next to
facilities emitting the same Radio Frequencies as the
TPM 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 TPM sensors.
