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.
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 situa-
tion 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.
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 switch is turned to the ON
position. It should turn off 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 autho-
rized 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.
