If the warning light stays on, or comes on when you're driving, there may be a problem with your ETS and your vehicle may need service. When this warning light is on, the system will not limit wheel spin. Adjust your driving accordingly. If the ETS warning light comes on and stays on for an extended period of time when the transmission shift lever is in any position other than LOW (L), your vehicle needs service. To limit wheel spin, especially in slippery road conditions, you should always leave the ETS on. But you can turn the system off if you prefer. To turn the system off, shift to LOW (L) or REVERSE (R). When you turn the system off, the ETS warning light will come on and stay on when the gear shift is in LOW (L). The warning light will not come on when the gear shift is in REVERSE (R). If the ETS is limiting wheel spin when you shift to LOW (L) or REVERSE (R) to turn the system off, the warning light will come on in LOW (L). But the system won't turn off right away. It will wait until there's no longer a current need to limit wheel spin. You can turn the system back on at any time by shifting to AUTOMATIC OVERDRIVE (D) or INTERMEDIATE (I). The ETS warning light should go off. Adding non-dealer/non-retailer accessories can affect your vehicle's performance. See Accessories and Modifications on page 5-3 for more information. 4-10 Limited-Slip Differential Your vehicle may have this feature. A limited-slip transmission can give you additional traction on snow, mud, ice, sand or gravel. It works like a standard transmission most of the time, but when one of the front wheels loses traction, this feature will allow the wheel with traction to move the vehicle. The limited slip design has minimal impact to the steering feel, but boosts the traction performance under all conditions. Electronic Stability Control (ESC) Your vehicle may have an Electronic Stability Control (ESC) system which combines antilock brake, and traction and stability control systems that help the driver maintain directional control of the vehicle in most driving conditions. When the vehicle is started and begins to move, the system performs several diagnostic checks to ensure there are no problems. You may hear or feel the system working. This is normal and does not mean there is a problem with your vehicle. The system should initialize before the vehicle reaches 20 mph (32 km/h). If the system fails to turn on or activate, the ESC/TCS light comes on, and the ESC OFF and/or SERVICE ESC message displays.
