4. Start the engine.
5. Rotate the steering wheel slightly more than one-half

turn to the left.

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

additional 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), functions 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 torque 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. The ESC

corrects for over/under steering of the vehicle by applying

the brake of the appropriate wheel to assist in counteract-

ing the over/under steer 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

appropriate for the steering wheel position.

Understeer - when the vehicle is turning less than

appropriate for the steering wheel position.
