Certain adverse driving maneuvers may activate the ESC system, which
include but are not limited to:
• Taking a turn too fast
• Maneuvering quickly to avoid an accident, pedestrian or obstacle
• Driving over a patch of ice or other slippery surfaces
• Changing lanes on a snow-rutted road
• Entering a snow-free road from a snow-covered side street, or vice
versa
• Entering a paved road from a gravel road, or vice versa
• Cornering while towing a heavily loaded trailer (refer to Trailer
towing in the Tires, Wheels and Loading chapter).
Switching Off AdvanceTrac
If the vehicle is stuck in snow, mud or sand, and seems to lose engine
power, switching off certain features of the AdvanceTrac system may be
beneficial because the wheels are allowed to spin. This will restore full
engine power and will enhance momentum through the obstacle.
To switch off the AdvanceTrac
system press the AdvanceTrac
control switch. Full features of the
AdvanceTrac system can be
restored by pressing the
AdvanceTrac control switch again
or by turning off and restarting the engine.
If you switch off the AdvanceTrac
system, the "sliding car off"
icon will illuminate steadily.
Pressing the AdvanceTrac control
switch again will turn off the "sliding
car off" icon.
In R (Reverse), ABS and the engine traction control and brake traction
control features will continue to function; however, ESC is disabled.
