200 SAFETY
6. Push the "ESC Off" button located in the lower switch
bank below the climate control four times within 20
seconds. The "ESC Off Indicator Light" should turn on
and turn off two times.
7. Rotate the steering wheel back to center and then an addi-
tional slightly more than one-half turn to the right.
8. Turn the ignition to the OFF mode and then back to ON.
If the sequence was completed properly, the "ESC Off
Indicator Light" will blink several times to confirm HSA
is disabled.
9. Repeat these steps if you want to return this feature to its
previous setting.
Traction Control System (TCS)
This system monitors the amount of wheel spin of each of the
driven wheels. If wheel spin is detected, the TCS may apply
brake pressure to the spinning wheel(s) and/or reduce
engine power to provide enhanced acceleration and stability.
A feature of the TCS, Brake Limited Differential (BLD), func-
tions similar to a limited slip differential and controls the
wheel spin across a driven axle. If one wheel on a driven axle
is spinning faster than the other, the system will apply the
brake of the spinning wheel. This will allow more engine
power to be applied to the wheel that is not spinning. BLD
may remain enabled even if TCS and ESC are in a reduced
mode.
Electronic Stability Control (ESC)
This system enhances directional control and stability of the
vehicle under various driving conditions. ESC corrects for
oversteering or understeering of the vehicle by applying the
brake of the appropriate wheel(s) to assist in counteracting
the oversteer or understeer condition. Engine power may
also be reduced to help the vehicle maintain the desired path.
ESC uses sensors in the vehicle to determine the vehicle path
intended by the driver and compares it to the actual path of
the vehicle. When the actual path does not match the
intended path, ESC applies the brake of the appropriate
wheel to assist in counteracting the oversteer or understeer
condition.
• Oversteer — when the vehicle is turning more than appro-
priate for the steering wheel position.
• Understeer — when the vehicle is turning less than appro-
priate for the steering wheel position.
