Electronic Stability Control (ESC)
This system enhances directional control and stability of the vehicle under various driving conditions. The ESC corrects for oversteering and understeering the vehicle by applying the brake of the appropriate wheel. Engine power may also be reduced to assist in counteracting the condition of oversteer or understeer and help the vehicle maintain the desired path.
The ESC uses sensors in the vehicle to determine the path that the driver intends to steer the vehicle and compares it to the actual path of the vehicle. When the actual path does not match the intended path, the ESC applies the brake of the appropriate wheel to assist in counteracting the condition of oversteer or understeer.
• Oversteer - when the vehicle is turning more than appropriate for the steering wheel position.
• Understeer - when the vehicle is turning less than appropriate for the steering wheel position.
ESC Operating Modes
The ESC system has two available operating modes:
ESC On
This is the normal operating mode for the ESC. Whenever the vehicle is started, the ESC system will be in this mode. This mode should be used for most driving conditions. The ESC should only be turned OFF for specific reasons as noted in the following paragraphs.
Partial Off
The “Partial Off” mode is intended for times when a more spirited driving experience is desired. It is also intended for driving in deep snow, sand, or gravel. This mode disables the TCS portion of the ESC and raises the threshold for ESC activation, which allows for more wheel spin than what ESC normally allows.
The “ESC Off” switch is located on the switch bank in the center of the instrument panel. To enter the “Partial Off” mode, momentarily press the “ESC Off” switch and the “ESC Activation/Malfunction Indicator Light” will illuminate.
To turn the ESC on again, momentarily press the “ESC Off” switch and the “ESC Activation/Malfunction Indicator Light” will turn off.
NOTE:
To improve the vehicle’s traction when driving
with snow chains, or when starting off in deep snow,
sand, or gravel, it may be desirable to switch to the
“Partial Off” mode by momentarily pressing the “ESC
Off” switch. Once the situation requiring “Partial Off”
mode is overcome, turn the ESC on again by momentarily
pressing the “ESC Off” switch. This may be done
while the vehicle is in motion.
WARNING!
The Electronic Stability Control (ESC) cannot prevent
the natural laws of physics from acting on the
vehicle, nor can it increase the traction afforded by
prevailing road conditions. ESC cannot prevent accidents,
including those resulting from excessive speed
in turns, driving on very slippery surfaces, or hydroplaning.
Only a safe, attentive, and skillful driver can prevent accidents. The capabilities of an ESC equipped vehicle must never be exploited in a reckless or dangerous manner which could jeopardize the user’s safety or the safety of others.
