Jeep WRANGLER 2017 Owner's Manual page 225

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 Off switch. 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 Off mode.
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.
