What does ESP stand for? I know what it does but I bought this car used and there was no owners manual. {not that that's any excuse} I read somewhere on here that someone said he got his esp disabled and the car pulled harder. Can't you just shut it off with the switch, or do you need to go into the computer to dissable it properly? And the obvious question, does it actually pull harder?

ESP stands for Electronic Stability Program. Per the owners manual...

"The system enhances directional control and stability of the vehicle under various driving conditions. The ESP 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 ESP 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 ESP applies the brake of the appropriate wheel to assist in counteracting the condition of oversteer or understeer.

The ESP/TCS indicator light, located in the instrument cluster, starts to flash as soon as the tires lose traction and the ESP system becomes active. The indicator light also flashes when the TCS (Traction Control System) is active. If the indicator light begins to flash during acceleration, ease up on the accelerator and apply as little throttle as possible. Be sure to adapt your speed and driving to the prevailing conditions.

The ESP OFF button is located in the center of the instrument panel. To turn OFF the ESP, momentarily press the ESP OFF button and the ESP/TCS indicator light will illuminate. To turn the system ON again, momentarily press the ESP OFF button and the indicator light will turn OFF.

When ESP is switched off, the engine torque reduction feature is cancelled. Therefore, the enhanced vehicle stability offered by ESP is unavailable. However, a feature of the system remains active. This feature controls wheel spin across an axle quite similarly to a limited slip differential. If one wheel on an axle is spinning faster than the other, the system will apply the brake of the spinning wheel and allow more engine torque to be applied to the wheel that is not spinning. This wheel slip control is active at vehicle speeds between approximately 24 mph and 50 mph.
