Dynamic Stability Control (DSC)
Dynamic Stability Control (DSC)
The DSC automatically controls braking and engine power output in conjunction with systems such as the ABS and TCS to help control side slip when driving on slippery surfaces, or during sudden or evasive steering, which enhances vehicle stability.
Also refer to Antilock Brake System (ABS) (Search), Traction Control System (TCS) (Search), and Kinematic Posture Control (KPC) (Search).
Warning and Cautions for Using the Dynamic Stability Control (DSC)
Do not rely on the Dynamic Stability Control as a substitute for safe driving.
The Dynamic Stability Control (DSC) cannot compensate for unsafe and reckless driving, excessive speed, tailgating (following another vehicle too closely), and hydroplaning (reduced tire friction and road contact because of water on the road surface). You can still have an accident.
-
Heed the following cautions so that the DSC can operate normally.
-
Use the specified tire size and the same type of tire on all 4 wheels.
-
Do not use tires with significantly different wear patterns on the same vehicle.
-
-
When using tires where the tire diameter is changed due to the installation of tire chains, or when installing an emergency spare tire, the DSC may not operate normally.
How to Use the Dynamic Stability Control (DSC)
Enabling Operation of the DSC
Drive the vehicle at a speed of about 20 km/h (13 mph) or faster.
The DSC is operable.
When the DSC operates, the TCS/DSC operation indicator light 
flashes.
Stopping Operation of the Traction Control System (TCS)/DSC/Kinematic Posture Control (KPC)
-
Switch the vehicle power ON.
-
Continue pressing the DSC OFF switch while the vehicle is stopped until a sound is activated.
Press the DSC OFF switch again to enable the TCS/DSC/KPC operation.

If the engine is stopped while the TCS/DSC/KPC operation is canceled, the TCS/DSC/KPC becomes operational when the engine is started the next time.
-
When the TCS/DSC/KPC is on and you attempt to free the vehicle from being stuck, the TCS/DSC/KPC will activate. Depressing the accelerator will not increase engine power and freeing the vehicle from being stuck might be difficult. When this happens, turn off the TCS/DSC/KPC.
-
If the TCS/DSC/KPC is canceled and the following systems are operated, the TCS/DSC/KPC becomes operational.

If the DSC OFF switch is pressed and held for 10 seconds or longer, the TCS/DSC/KPC operation can no longer be turned off even if the DSC OFF switch or DSC-TRACK switch is pressed. In this case, the DSC OFF switch or DSC-TRACK switch will operate normally when the vehicle power is switched ON again after being switched OFF.
