132 UNDERSTANDING THE FEATURES OF YOUR VEHICLE NOTE: To improve the vehicle's traction when driving with snow chains, or starting off in deep snow, sand or gravel, it may be desirable to switch to the "Partial Off" mode by pressing the ESP switch. Once the situation requiring ESP to be switched to the "Partial Off" mode is overcome, turn ESP back on by momentarily depressing the "ESP Control Switch". This may be done while the vehicle is in motion. 4WD Low Range Partial Off This is the normal operating mode for ESP in 4WD low range. Whenever the vehicle is started in 4WD low range or the transfer case (if equipped) is shifted from 2WD, 4WD high range, or neutral to 4WD low range, the ESP system will be in this mode. In 4WD low range, ESP and TCS, except for the "limited slip" feature described in the TCS section, are turned off until the vehicle reaches a speed of 30 mph (48 km/h). At 30 mph (48 km/h), the normal ESP stability function returns but TCS remains off. When the vehicle speed drops below 25 mph (40 km/h) the ESP system shuts off. ESP is off at low vehicle speeds in 4WD low range so that it will not interfere with off-road driving but ESP function returns to provide the stability feature at speeds above 30 mph (48 km/h). The "ESP/TCS Indicator Light" will always be illuminated in 4WD low range when ESP is off. ESP/BAS Warning Lamp The malfunction indicator lamp for the ESP is combined with BAS. The "ESP/BAS Warning Lamp" and the "ESP/TCS Indicator Light" in the instrument cluster both come on when the ignition switch is turned to the "ON" position. They should go out with the engine running. If the "ESP/BAS Warning Lamp" comes on continuously with the engine running, a malfunction has been detected in either the ESP or the BAS system. If this light remains on after several ignition cycles, and the vehicle has been driven
