2013 JEEP WRANGLER UNLIMITED snow chains

When in  Partial Off  mode, the TCS portion of ESC has
been disabled and the “ESC Activation/Malfunction
Indicator Light” will be illuminated. All other stability features of ESC 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 ESC would normally allow is required to gain
traction. To turn ESC on again, momentarily press 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 “Partial Off”
mode by pressing the ESC OFF switch. Once the situation
requiring ESC to be switched to the “Partial Off” mode is
overcome, turn ESC back on by momentarily pressing the
ESC OFF switch. This may be done while the vehicle is in
motion.
When in ESC Off mode, ESC and TCS, except for the
“limited slip” feature described in the TCS section, are
turned off. To turn ESC on again, momentarily press theESC OFF Switch

WARNING!With the ESC switched off, the enhanced vehicle
stability offered by ESC and ERM are unavailable.
In an emergency evasive maneuver, the ESC and
ERM systems will not engage to assist in maintaining
stability. The “Full Off” mode is intended for off-
road use only.
2H Range (4WD Models) Or 2WD Models
On
This is the normal operating mode for ESC in 2H range
and on 2WD vehicles.

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 press the
ESC OFF switch. This will restore the normal “ESC On”
mode of operation.

snow chains, or starting off in deep snow, sand, or gravel, it
may be desirable to switch to the “Partial Off” mode by
pressing the ESC OFF switch. Once the situation requiring
ESC to be switched to the “Partial Off” mode is overcome,
turn ESC back on by momentarily pressing the ESC OFF
switch. This may be done while the vehicle is in motion.

3. Lots 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.
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). 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 Monitor-
ing Telltale Light” will flash on and off for 75 seconds
and then remain on solid. For each subsequent ignition
key cycle, a chime will sound and the “Tire Pressure
Monitoring Telltale Light” will flash on and off for
75 seconds and then remain on solid. Once you repair
or replace the original road tire, and reinstall it on the
vehicle in place of the spare tire, the TPMS will update
automatically and the “Tire Pressure Monitoring Tell-
tale Light” will turn OFF, as long as no tire pressure is500 STARTING AND OPERATING

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:
1. Jamming due to electronic devices or driving next to
facilities emitting the same Radio Frequencies as the
TPM sensors.
2. Installing some form of aftermarket window tinting
that affects radio wave signals.
3. Lots 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. The EVIC will also display a  SERVICE TPM SYSTEM 
message for a minimum of five seconds when a system
fault is detected possibly related to an incorrect sensor
location fault. In this case, the  SERVICE TPM SYSTEM 
message is then followed by a graphic display, with
pressure values still shown. This indicates the pressure
values are still being received from the TPM Sensors but
they may not be located in the correct vehicle position.
However, the system still needs to be serviced as long as
the  SERVICE TPM SYSTEM  message exists.
