STARTING AND OPERATING 355 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. All 4WD vehicles in Auto and 4HI Modes can also choose the following ESP operating mode. This is the only ESP operating mode in 4LO: ESP Off This mode is intended for off-road use when ESP stability features could inhibit vehicle maneuverability due to trail conditions. This mode is entered by depressing and holding the "ESP Control Switch" for 5 seconds when the vehicle is stopped and the engine is running. After 5 seconds, the "ESP/TCS Indicator Light" will illuminate and the "ESP Off" message will appear in the odometer. Press and release the trip odometer button located on the instrument cluster to clear this message. In this mode, ESP and TCS, except for the "limited Slip" feature described in the TCS section, are turned off until the vehicle reaches a speed of 40 mph (64 km/h). At 40 mph (64 km/h) the system returns to "Partial Off" mode, described above. When the vehicle speed drops below 35 WARNING! In the Partial Off mode, the engine torque reduction and stability features are desensitized. Therefore, the enhanced vehicle stability offered by ESP is unavailable. 5
